Burglarproof lock for an electrical device

Locks for electronic devices

This creation is about a kind of lock, and especially about an anti-theft lock for electronic devices.

In modern life, consumer electronic products play an important role, coupled with the fast-paced lifestyle and people's demand for real-time information, portable electronic products have become one of the necessities of people. However, these products are more likely to be stolen or stolen due to their higher unit price and ease of realization.

In order to prevent others from stealing, a lock structure is designed. For example, a laptop lock can be connected to the anti-theft lock hole of an electronic product with its lock, and then the movement of the lock can be controlled by the mechanism of the key lock. The purpose of opening/closing. In the use of the key-only lock, the key must be inserted into the lock hole to control the movement of the lock member or the opening/closing of the lock, so that the user must accurately align the key with the lock hole and insert it, which increases the inconvenience of operation. Furthermore, after the electronic product is locked, the key must be stored separately, which increases the trouble of storing, and at the same time there is the problem of accidentally losing the key. Therefore, there is room for improvement no matter in operation mode or structural design.

The main purpose of this creation is to provide a lock that can be combined with a combination lock to prevent electronic products from being stolen.

Another purpose of this creation is to provide a lock that is easy to operate and can be quickly connected/disconnected.

This creation provides a combination lock that can be connected to the keyhole of an electronic device, which includes a housing, a lock body, an operating device, and a rotating fastener. The shell is formed with a lock-through part composed of two mutually separated columnar structures, and a through hole communicating with the inside of the shell is formed between the two column-shaped structures of the lock-through part; the extension part of the rotating fastener is formed by the through hole It protrudes and extends along the lock-through part, and a non-return part is formed at the end of the extension part to form a T-shaped structure; the lock is connected with the electronic device through the T-shaped structure and the lock-through part. The lock body includes a rod that can move in the axial direction and a plurality of character wheels on which the rods are sleeved. When the character wheel is turned to make the number correct and the lock is unlocked, the lock body will release the axial displacement of the rod. Wherein, when the operating device is pressed, the displacement generated by the operating device enables the guide surface provided on the operating device to push the rod, which causes the rod to produce axial displacement, and at the same time drives the rotation of the rotary fastener.

Therefore, when the user rotates the character wheel to the correct position corresponding to the code and reaches the unlocked state, the rod of the lock body can be allowed to move axially. At this time, pressing the operating device can make the rotating fastener rotate so that the rotating fastener stops. The extension direction of the back part is parallel to the virtual connection direction of the two columnar structures of the lock-through part. At this time, the part of the lock connected to the keyhole of the electronic device (ie the lock-through part, the extension part, and the non-return part) can be inserted into the lock Or, if the part of the lock connected with the keyhole is already in the keyhole, it can be detached from the keyhole at this time. When you finish pressing the operating device, the operating device will return to the original position, and the rotating fastener will also return to the original position at the same time. At this time, the extension direction of the non-return portion of the rotating fastener is perpendicular to the virtual connection direction of the two columnar structures of the lock-through portion, that is, the non-return portion and the lock-through portion form a cross shape and engage with the keyhole of the electronic device, so that the lock is Do not detach from the electronic device, at this time, you can move the character wheel of the lock body at will to reach the upper The purpose of the lock.

This creation is to provide a lock for electronic devices. In a preferred embodiment, the electronic device may include any electronic device with a keyhole, including but not limited to, for example, a notebook computer. As shown in FIG. 1, the lock 10 includes a housing 100, a lock body 20, an operating device 30, and a rotating fastener 40. The housing 100 forms at least one cavity (not shown in the figure) for at least partially accommodating the lock body 20, the operating device 30, and the rotating fastener 40. The flexible chain 13 can be connected to the housing 100 for fixing the electronic device to a specific object, such as a table. A piercing part 1031 is protrudingly provided on one end of the housing 100; the piercing part 1031 is two mutually separated columnar structures, the columnar structure can be, for example, a cylinder cut into two opposite separated semi-cylinder parts, It is used to limit the lateral displacement in one dimension. A through hole 1032 communicating with the inside of the housing 100 is formed between the two columnar structures of the locking portion 1031, that is, the through hole 1032 communicates with the cavity. The rotating fastener 40 has an extension portion 402 that can extend from the perforation 1032 and extends along the locking portion 1031, and a non-return portion 403 is formed at the end of the extension portion 402, thus forming a T-shaped structure. The T-shaped structure and the piercing portion 1031 can be selectively engaged with the key hole of the electronic device to lock the electronic device to a specific object. The structure, connection and function relationship of the housing 100, the lock body 20, the operating device 30, and the rotary fastener 40 are described in detail later.

Figure 2 shows an exploded view of the embodiment of the creative lock. As shown in FIG. 2, the housing 100 is preferably formed by combining several housing parts. For example, the housing 100 includes a first housing portion 101 and a second housing portion 102, which are engaged with each other by an engaging mechanism to form a cavity for accommodating other components of the lock, as described above. In one embodiment, the first housing part 101 has a plurality of combined columns 112, and the second housing part 102 has a plurality of combined holes 122 corresponding to the plurality of combined columns 112 of the first housing part 101. The above-mentioned combination hole 122 is engaged with the corresponding combination post 112 to assemble the first housing portion 101 and the second housing portion 102 into a housing 100 in which the lock body 20 is accommodated. In a preferred embodiment, the lock body 20 can be a combination lock with a plural number wheel 202. In this situation, the first housing portion 101 and the second housing portion 102 may each have a plurality of exposed holes 111 to correspond to the character wheel 202 of the combination lock. When the lock body 20 of the combination lock is set in the cavity of the housing 100, the character wheel 202 is partially exposed to the exposed hole 111 for the user to operate; that is, the user can rotate the character wheel exposed in the exposed hole 111 202, and achieve the purpose of unlocking or locking. Furthermore, the connecting head 103 is arranged at the end of the cylindrical shell formed by the first housing part 101 and the second housing part 102, and is combined with the first housing part 101 and the second housing part 102; wherein A through-lock portion 1031 is formed on one side of the connector 103 for the lock body 10 to connect with the lock hole of the electronic device. As described above, the locking portion 1031 may be two separate columnar structures, and a through hole 1032 communicating with the cavity is formed between the two columnar structures. Where the first housing part 101, the second housing part 102 and the connector 103 are connected, a shell ring 104 is further provided. For example, the connector 103 is disposed inside one end of the housing 100, and the shell ring 104 covers the end of the housing 100 where the connector 103 is provided, forming the appearance of the shell ring 104 surrounding the connector 103 at the end of the housing 100. As shown in Figure 1. In this embodiment, the shell ring 104 has a protrusion 12 for fixing the flexible chain 13. It should be noted here that the connection mechanism between the protrusion 12 of the shell ring 104 and the flexible chain 13, as well as the connection mechanism between the connector 103, the shell ring 104 and the housing 100 can be achieved by any conventional means, such as locking, Adhesion, locking, etc., will not be repeated here.

Furthermore, in this embodiment, as shown in FIG. 2, the lock body 20 disposed in the cavity of the housing 100 is a combination lock, which includes an axially movable rod 201 and a plurality of characters sleeved on the rod 201 Round 202. When the user rotates the character wheel 202 to the correct position corresponding to the password and reaches the unlocked state, the rod 201 of the lock body 20 can be allowed to move axially. Conversely, when the character wheel 202 is not rotated to the correct position corresponding to the password and is in the locked state, the rod 201 cannot perform axial displacement. The related operations and operating principles of the lever 201 of the lock body 20 and the character wheel 202 for unlocking and locking are well known to those skilled in the art, and will not be repeated here. The connection and action relationship between the rod 201 and other elements of the lock 10 will be described in detail below.

As shown in FIG. 2, one end of the rod 201 is provided with a baffle 2011, and a receiving groove 2012 is formed thereon for the elastic element 303 to be received therein (described later). The baffle 2011 of the rod 201 is used to connect the operating device 30 to perform linkage in response to the operation of the operating device 30. As shown in FIGS. 2 and 3A-3B, the operating device 30 is arranged on one side of the housing 100 and corresponds to the rod 201 of the lock body 20. The operating device 30 has a guiding surface 301 and an actuating portion 302, wherein the guiding surface 301 of the operating device 30 conflicts with the end of the baffle 2011. The guiding surface 301 may be an inclined surface. The operating device 30 is further provided with the aforementioned elastic element 303, which is preferably a spring or other elastic element. The elastic element 303 is located between the operating device 30 and the rod 201 and is accommodated in the accommodating groove 2012 of the baffle 2011. The elastic element 303 selectively provides elastic force in response to the action of the operating device 30. The actuating portion 302 of the operating device 30 and the rotating fastener 40 are interlocked with each other, which will be described in detail later. As shown in FIGS. 2 and 3A-3B, the rotating fastener 40 is disposed on one side of the operating device 30, opposite to the baffle 2011 of the rod 201 of the lock body 20. The rotating fastener 40 includes a latching portion 401, an extending portion 402, and a non-returning portion 403. In the preferred embodiment of the present creation, as shown in FIG. 3A, the connector 103 is sleeved on the rotating fastener 40, so that the extension portion 402 and the non-return portion 403 pass through the perforation 1032 of the connector 103 and run along the center of the connector 103. The locking portion 1031 extends, and the non-return portion 403 protrudes from the end of the locking portion 1031 of the columnar structure. When the rotary fastener 40 rotates, the extension direction of the non-return portion 403 perpendicular to the extension portion 402 is correspondingly changed, so that the extension direction of the non-return portion 403 is selectively aligned with the two columnar structures of the lock-through portion 1031. The virtual connection direction is parallel or vertical to operate the connection and selective engagement between the lock 10 and the keyhole of the electronic device, which will be described in detail later.

The locking portion 401 of the rotating fastener 40 is disposed in the cavity of the housing 100 relative to the extension portion 402 and the non-return portion 403. In addition, the connecting head 103 is separated from the baffle 2011 by a distance D. As shown in FIGS. 3A-3B, the latching portion 401 of the rotating fastener 40 abuts against the actuating portion 302 of the operating device 30, so the rotating fastener 40 can be relatively rotated in response to the operation of the operating device 30 to change the non-return The position of the portion 403 relative to the locking portion 1031 of the connector 103. For example, in the preferred embodiment of the present creation, the structure of the locking portion 401 is a gear-like structure, and the structure of the actuating portion 302 is formed as a rack-like structure in cooperation with the gear structure of the locking portion 401. As shown in FIGS. 3C-3D and FIG. 3D in the AA' direction cross-sectional view 3E, the groove of the rack-shaped actuating portion 302 of the operating device 30 engages with the protruding teeth of the gear-shaped latch portion 401; this 3A and 3F, it can be seen that the non-return portion 403 of the rotating fastener 40 is perpendicular to the lock-through portion 1031 (that is, the extension direction of the non-return portion 403 is perpendicular to the virtual line of the two columnar structures of the lock-through portion 1031 Direction), and the connector 103 is viewed from the outer side of the housing 100, as shown in FIG. 3F, a cross-shaped structure can be seen. With this structure, the non-return portion 403 protrudes from the projection range of the locking portion 1031 to facilitate the engagement with the key hole of the electronic device. That is, when the part of the lock 10 connected with the key hole of the electronic device (ie, the penetration part 1031, the extension part 402, and the non-return part 403) is inserted into the key hole, the actuating part of the operating device 30 and the 302 rotating fastener The interlocking movement of the latching portion 401 of 40 can make the non-return portion 403 protrude from the lock-through portion 1031 into a cross shape, so that the lock 10 cannot be detached from the lock hole without being unlocked, so as to achieve the purpose of protecting the electronic device.

When the zigzag wheel 202 of the lock body 20 rotates to the position corresponding to the code and is in an unlocked state, the rod 201 of the lock body 20 can be allowed to move axially. At this time, as shown in FIG. 4A, because the rod 201 can be displaced in the axial direction, the user can press the operating device 30 to displace the guide surface 301 toward the rod 201 and push the rod 201 along the guide surface 301. (Ie, the inclined surface) axially shifts and compresses the elastic element 303 due to pressing. At this time, the distance D between the connector 103 and the baffle 2011 increases to D. In other words, in the unlocked state, the displacement of the operating device 30 is not restricted by the rod 201. Therefore, while pressing the operating device 30, the actuating portion 302 of the operating device 30 drives the latching portion 401 of the rotating fastener 40 to rotate the rotating fastener 40. In a preferred embodiment, the rotation angle is 90°. At this time, as shown in FIGS. 4B-4E, the operating device 30 will push the gear-shaped latching portion 401 to rotate with the rack-shaped actuating portion 302 after being pressed, and generate a displacement from Bto B. At this time, from the angles shown in Figures 4A and 4F, it can be seen that the pressing of the operating device 30 causes the non-return portion 403 of the rotary fastener 40 to rotate parallel to the lock-through portion 1031 (that is, the extension direction of the non-return portion 403 is parallel to the lock-through portion The virtual connection direction of the two columnar structures of 1031), and the connector 103 is viewed from the outer side of the housing 100, which can be in a line-shaped structure. This structure enables the non-return portion 403 to be in the projection range of the piercing portion 1031 to facilitate separation from the lock hole or self-lock hole into which the electronic device is inserted. That is, when the part of the lock 10 connected to the key hole of the electronic device (ie the piercing part 1031, the extension part 402, and the non-return part 403) is inserted into the key hole, and the non-return part 403 protrudes from the piercing part 1031 into a cross In the locked state, the character wheel 202 of the lock body 20 is unlocked to allow the rod 201 to move axially, and the operating device 30 is actuated (ie pressed) to drive the non-return portion of the rotating fastener 40 The 403 rotates, and the lock 10 can be easily removed from the locking hole. This operation does not require precise alignment or rotation, which increases the convenience of use.

When the lock 10 is connected or disconnected from the keyhole and the pressing on the operating device 30 is released, the compression on the elastic element 303 is also released. At this time, the elastic force provided by the elastic element 303 will restore the operating device 30 to the position before pressing. At the same time, the rotating fastener 40 is also interlocked to rotate, for example, 90° to return to the position shown in FIG. 3F. That is, when the lock body 20 is in the unlocked state, the penetration portion 1031, the extension portion 402, and the non-return portion 403 of the lock 10 can be inserted into the lock hole of the electronic device in a straight line by pressing the operating device 30. After that, as long as the pressing 30 on the operating device is released, the non-return portion 403 and the piercing portion 1031 can be cross-shaped and engage with the keyhole of the electronic device, so that the lock 10 will not be separated from the electronic device. Toggling the character wheel 202 of the lock body 20 can achieve the purpose of locking, which significantly simplifies the operating procedure.

In other different embodiments, the connection relationship between the actuating portion 302 of the operating device 30 and the latching portion 401 of the rotating fastener 40 is not limited to the rack and gear mentioned above, and any rotating fastener can be driven by the actuation of the operating device 30 The mechanism of 40 rotation can be applied to this creation. As shown in Figures 5A-5C, the end of the actuating portion 302 can be designed as a plane and it can interfere with the latching portion 401 of the rotating fastener 40. On the contrary, the latching portion 401 of the rotating fastener 40 is designed to be flat. The shaped actuating part 302 pushes the rotating rotating bar. When the lock body 20 is in the unlocked state, the displacement caused by the pressing of the operating device 30 will cause the plane of the actuating portion 302 to push the locking portion 401 to drive the rotation of the rotary fastener 40 (not shown), thereby changing the non-return portion 403 bearing. Regarding the operation principle and connection relationship of the components in this embodiment, please refer to the foregoing embodiment, which will not be repeated here.

In another embodiment, as shown in FIGS. 6A-6D, the operating device 30 is connected to a tight compression spring 50, which is disposed in the groove 1035 and the other end is in conflict with the latching portion 401; The groove 1035 is provided on the side of the connecting head 103 facing the cavity 11 for accommodating the tight spring 50. Figure 6A shows the position of the operating device 30, the close compression spring 50, and the latching portion 401 when the operating device 30 is not pressed. At this time, as shown in Figure 6B, the non-return portion 403 of the rotary fastener is perpendicular to the through-lockunit1031. As shown in FIG. 6C, the displacement caused by pressing the operating device 30 will drive the rotation of the rotary fastener by pushing the latching portion 401 against the compression spring 50; after rotation, as shown in FIG. 6D, the non-return portion 403 and the through lock The parts 1031 are parallel, so that the lock-through part 1031 can enter the lock hole together with the non-return part 403 or escape from the lock hole.

The above-mentioned embodiments are used to describe the creation, but the creation method and structure can still be modified and changed without departing from the essence of the creation. Therefore, this creation is not limited to the description of the above specific embodiments, and the patent application scope of this creation is intended to include all such modifications and changes, so as to truly conform to the spirit and scope of this creation.
