Rotary shaft device, support frame and photographing device

The present invention relates to a rotary shaft device and a support frame and a photographing device having the rotary shaft device, and more particularly to a rotary shaft device having a positioning function and a support frame and a photographing device having the rotary shaft device.

Currently, the hanging photography (or camera) device on the market mostly adjusts the position and angle of the camera in two parts. The adjustment of the angle can be further divided into an angle adjustment between the cantilever and the camera fixed thereon, and an adjustment of the rotation angle of the cantilever and its fixed bracket. Please refer to Figure 1A. Figure 1A shows a partial top view of a conventional overhead photography device. The photographing device includes a fixed bracket 12 and a cantilever 14. The fixing bracket 12 is fixed to the wall surface 10, and the suspension arm 14 is pivotally connected to the fixing bracket 12. The broken line portion in Fig. 1A indicates the position of the hanging wall 14 when the photographing apparatus is housed. Therefore, when a camera (not shown in FIG. 1A) that is connected to the other end of the suspension wall 14 is to be used, the suspension wall 14 will be displaced from the position at which it is stored, for example, as shown in FIG. Show location. It is also necessary to fix the position of the suspension wall 14 relative to the fixed bracket 12, that is, the relative rotation angle.

At present, there are two types of the above-mentioned cantilever 14 and the fixed bracket 12: one is threaded locking; the other is a quick release positioning method using a cam structure. Please refer to FIG. 1B. FIG. 1B is a schematic view showing the manner of thread locking. The fixing bracket 12' in Fig. 1B has an open C-shaped clamping ring, and a fixing portion 12a and an adjusting portion 12b are formed at the opening. A screw hole is formed in the adjusting portion 12b, and a bolt 12c is locked thereto. One end of the bolt 12c is fixed to the fixing portion 12b, and the other end is locked to the screw portion 12d. By rotating the screwing portion 12d to force the adjusting portion 12b to move toward the fixing portion 12a, the C-shaped clamping ring of the fixing bracket 12' is clamped to the fixed shaft 142 of the hanging wall 14', thereby achieving the purpose of fixing the hanging wall 14'. . However, the fixing force in this manner depends on the degree of tightening of the tightening portion 12d, is difficult to control, and has no positioning function. In addition, the long-term excessive fixed force easily deforms the C-shaped clamping ring and gradually disables the clamping function.

See Figure 1C for another way to fix it. Figure 1C shows a schematic diagram of the quick release positioning mode. Different from the locking mode shown in FIG. 1B, the fixing portion 12a' and the adjusting portion 12b' of FIG. 1C are formed with substantially coaxial through holes, and a cylinder 12c' penetrates the through hole. One end of the cylinder 12c' includes a stopper portion 12c" to prevent the fixing portion 12a' from slipping out of the cylinder 12c'. The other end of the cylinder 12c' is pivotally connected to the wrench 12d'. The wrench 12d' has a cam structure 12d", so The adjusting portion 12b' is pressed to move to the fixing portion 12a', so that the C-shaped clamping ring of the fixing bracket 12' is clamped to the rotating shaft 142 which is fixed to the hanging wall 14', thereby achieving the purpose of fixing the hanging wall 14'. Wherein, the cam structure 12d" uses the rubber washer 12e to produce a positioning effect. However, the cam structure 12d used in this manner may be hardened or cracked due to long-term use or excessive acceptance of the rubber gasket 12e, resulting in insufficient locking force. And there is no positioning function. In addition, since the quick-release wrench 12d' protrudes from the bracket structure, it is easy to loosen due to the touch, which makes the fixing function invalid.

Therefore, the conventional fixed cantilever method, in addition to the fixed structure design, is easy to be disabled due to human operation or long-term use, and has no positioning function, resulting in inconvenience in fixed operation.

One of the scope of this creation is to provide a rotary shaft device having a positioning function.

One of the scope of the present invention is to provide a support frame and a photographing apparatus having the aforementioned rotary shaft device.

The rotary shaft device of the present invention includes a first rotating member, a second rotating shaft member, and a positioning member. The first rotating member includes a first positioning recessed space and a second positioning recessed space. The second rotating member is pivotally coupled to the first rotating member, and the second rotating member includes a hole. The positioning component comprises a body, an elastic body and a positioning portion. The body comprises an accommodating space, and the elastic body is accommodated in the accommodating space and connects the body and the positioning portion. The body is disposed in the hole and connected to the second rotating member, and the positioning portion is received in the first positioning recess space or the second positioning recess space against the first rotating member.

Therefore, the present invention can achieve the positioning function by the positioning portion pressing the first positioning recessed space or the second positioning recessed space without clamping the rotating shaft, and by positioning the position and quantity of the recessed space, multi-segment positioning can be achieved. Operate and increase structural reliability.

The support frame of the present invention comprises the aforementioned rotating shaft device, a first bracket and a second bracket, wherein the first bracket is coupled to the first rotating member and the second bracket is coupled to the second rotating member. Therefore, this creation can provide a support structure with rotational positioning, which is beneficial to the support needs of the positioning function.

The photographic apparatus of the present invention comprises the aforementioned support frame and a camera, wherein the camera is coupled to the second support. Therefore, the present invention can provide a photographic device with rotational positioning, which solves the lack of the fixed structure of the conventional cantilever type photographic device, and increases the positioning function, making the accommodating operation and setting operation easier, and increasing the stability of the structure and the overall device. The service life.

The advantages and spirit of this creation can be further understood by the following detailed description of the creation and the drawings.

Please refer to Figure 2. 2 is a schematic diagram of a photographing apparatus 2 in accordance with a preferred embodiment of the present invention. The photographing device 2 mainly includes a camera 22 to support the support frame 24 of the camera 22; the support frame 24 and is fixed to the wall surface 20. As shown in FIG. 2, through the positioning design of the spindle device 242 of the present invention, the camera 22 has two positioning positions with respect to the wall surface 20 (the dotted line is another positioning position of the solid line), and can be used as the use position and the storage position. use. Of course, this creation is not limited to this, and it can provide more stages of positioning depending on the needs of use.

Please refer to Figure 3. FIG. 3 is an exploded view of the photographing device 2. The support frame 24 includes a first bracket 244, a shaft device 242, and a second bracket 246. The first bracket 244 includes a fixing bracket 2442 and an outer cover formed by combining the upper cover 2444 and the lower cover 2446. The first bracket 244 is coupled to the spindle device 242 via a mounting bracket 2442. The second bracket 246 includes a fixed bracket 2462 and an extension bracket 2464 coupled thereto. The second bracket 246 is coupled to the spindle device 242 via a fixed bracket 2462. The camera 22 includes a lens 222 and a lens holder 224. The lens holder 224 connects the lens 222 and the extension bracket 2464 of the second bracket 246. The lens 222 is pivotally connected to the lens holder 224 to be rotatable relative to the lens holder 224.

Please refer to Figure 4. FIG. 4 is an exploded view of the rotating shaft device 242 of FIG. The spindle device 242 includes a first rotating member composed of a first base 2422a, a second base 2422b and a shaft 2422c, a second rotating member 2424 pivotally coupled to the first rotating member, and two positioning members 2426. The shaft 2422c is located between the first base 2422a and the second base 2422b and is fixed to the second base 2422b. One end of the shaft 2422c is a non-circular end portion 2422g, and the first base 2422a includes a fixing hole 2422f that is engageable with the end portion and does not cause relative movement of the first base 2422a and the second base 2422b. See Figure 5C for the connection method. The second rotating member 2424 is pivotally coupled to the shaft 2422c by a shaft hole 2424c and includes two holes 2424a for receiving the positioning member 2426 such that the positioning member 2426 connects the second rotating member 2424 and abuts the first base 2422a. The first positioning recessed space 2422e or the second positioning recessed space 2422e' formed on the first base 2422a is abutted (see FIGS. 5B and 5C) to achieve the positioning function. In addition, the second rotating member 2424 includes a limiting post 2424b, and the second base 2422b includes a chute 2422d, and the limiting post 2424b is restrictedly slid in the chute 2422d. Thereby, the range of rotation of the second rotating member 2424 relative to the first rotating member can be limited.

In addition, in the preferred embodiment, the fixing bracket 2462 is coupled to the second rotating member 2424 by two cantilevers 2462a. As shown in FIG. 4, the second rotating member 2424 is formed with two screw holes 2424d, and the cantilever 2462a can be locked to the two screw holes 2424d of the second rotating member 2424 by screws (not shown). However, this creation is not limited to this. For example, a hole is formed in the second rotating member 2424, and the fixing bracket 2462 correspondingly includes a cylinder to be inserted into the hole for the purpose of fixed connection. Or lock with a thread.

Please refer to Figure 5A to V.C. Figure 5A shows a top view of the spindle assembly 242. FIG. 5B is a bottom view showing the first pedestal 2422a. Figure 5C is a cross-sectional view of the spindle device 242 taken along section line XX of Figure 5A. As shown in FIG. 5C, the non-circular end portion 2422g of the shaft 2422c is inserted only into the partial fixing hole 2422f of the first base 2422a, and the fixing hole 2422f is locked into the shaft 2422c by screws (not shown). The second base 2422a is fixedly coupled to the shaft 2422c in the screw hole of the end. Of course, a washer is placed between the screw and the end of the shaft 2422c. In addition, the present invention also needs to realize the connection between the first pedestal 2422a and the second pedestal 2422b by simply fitting the hole axis, and the section of the fixing hole 2422f is not necessary to be the same as the end of the shaft 2422c, only the phase is required. Just can.

As shown in Figure 5C, the positioning element 2426 includes a positioning portion, a body 2426b, and an elastomer. The positioning portion can be a metal sphere, such as steel ball 2426a. The elastomer can be spring 2426c. The body 2426b includes an accommodating space for accommodating the spring 2426c and a portion of the steel ball 2426a. The steel ball 2426a is bound by the opening of the accommodating space formed by the body 2426b, and compresses the spring 2426c. The engagement of the positioning member 2426 with the hole 2424a of the second rotating member 2424 can be a tight fit or a cooperation of male and female threads. For example, the hole 2424a of the second rotating member 2424 includes a female thread, and the body 2426b of the positioning member 2426 includes the female Male thread with thread matching. Or when the hole 2424a of the second rotating member 2424 is a blind hole or a structure of the retainable body 2426b, for example, a through hole having a stepped inner diameter, the body 2426b of the positioning member 2426 can be simply disposed in the hole 2424a. You can achieve the purpose of the connection.

Referring to FIG. 5B, the steel ball 2426a abuts against the first positioning recessed space 2422e of the first base 2422a. Therefore, when the second rotating member 2424 is rotated relative to the first rotating member, since the body 2426b of the positioning member 2426 does not move in the vertical direction relative to the second rotating member 2424, the steel ball 2426a will move downward and compress the spring 2426c, such as Figure 5D shows. When the second rotating member 2424 is rotated by 90 degrees, the steel ball 2426a will release a portion of the pressure against the spring and into the second positioning recessed space 2422e' to achieve the positioning function. In addition, when the positioning member 2426 is engaged with the hole 2424a of the second rotating member 2424 by a thread, the bottom of the body 2426b of the positioning member 2426 can form a flat or cross-shaped groove, and the user can adjust the positioning member 2426 and the first base. The relative distance of 2422a, that is, the force of the adjustment ball 2426a against the first base 2422a. For example, lowering the positioning element 2426 in Figure 5C reduces the force applied to the first base 2422a. It should be noted that the contours of the positioning recessed spaces 2422e and 2422e' are not necessarily the same as the steel balls 2426a, and only need to be accommodated. In other words, the positioning recessed spaces 2422e, 2422e' may also be blind holes or through holes or the like.

Please refer to Figure 5B. Figure 5B shows that the spindle assembly 242 has two positioning positions and is at an angle of 90 degrees. And see the perspective view of Figure 2. The steel ball 2426a of the positioning component 2426 of the photographic device 2 of Fig. 2 is located in the first positioning recessed space 2422e, that is, the second bracket 246 is located in the first direction D1, and the storage position (shown by the broken line in Fig. 2) Located in the second direction D2, the angle θ between the two directions D1 and D2 is 90 degrees. However, this creation is not limited to this. In addition to the angle θ can be other desired angles, such as 30 degrees, 45 degrees or 60 degrees, the positioning angle θ is not limited to a single one, but also multiple sets of positioning angle, depending on the product design. And in the same positioning angle, the number of positioning connection structures is not limited to a single one, depending on the product design, for example, a large positioning force is required, or a structurally stable positioning is required.

Please refer to Figure 6A. FIG. 6A is a schematic view showing the fixing frame 2442 of the first bracket 244 of FIG. The fixing frame 2442 includes a fixing plate 2442a for fixing the first base 2422a and the second base 2422b of the rotating shaft device 242. Please also refer to Figure 6B. FIG. 6B is a schematic view showing the upper cover 244 of the first bracket 244 of FIG. The fixing frame 2442 includes four guiding plates 2442b. The upper cover 2444 includes two sliding slots 2444a (the clamping cover 2446 also includes two sliding slots), and the guiding plate 2442b slides into the sliding slot 2444a, so that the upper cover 2444 and the fixing bracket 2442 are correct. Connected to the ground. In addition, the fixing frame 2442 includes four bumps 2442c, and the upper cover 2444 includes two holding holes 2444b (or recesses), and the bumps 2442c are held in the holding holes 2444b to assist in clamping the upper cover 2444 on the fixing frame 2442. .

It should be noted that, in the preferred embodiment, the fixing plate 2442a is locked to the first base 2422a and the second base 2422b of the rotating shaft device 242 by two screws (not shown). . For example, the fixing plate 2442a is directly bonded or welded to the first base 2422a and the second base 2422b, or the first base 2422a and the second base 2422b are directly formed integrally with the fixing plate 2442a. That is, in a specific embodiment, the fixing plate 2442a directly serves as the first base 2422a and the second base 2422b.

Please refer to Figure 6C. Figure 6C is a schematic view of a portion of the support frame 24 of Figure 2. The view angle of Figure 6C is different from the view angle of Figure 2, and the dashed line is used to express the approximate position of the relevant component within the cover. The figure shows that the outer cover is engaged with the fixing frame 2442 and forms a line accommodating space S for accommodating the required line. The lower cover 2446 includes a hole 2446a that connects the line accommodation space S with the outside. An external line can pass through the hole 2446a to be disposed in the line accommodation space. At the same time, the lines disposed in the line accommodating space may be disposed on the wire harness loops on the plurality of holes 2442d of the fixing frame 2442.

In summary, the present invention is different from the prior art in that the positioning portion can be pressed against the first positioning recessed space or the second positioning recessed space to achieve the positioning function without clamping the rotating shaft, and by positioning the position and quantity of the recessed space. With settings, multi-segment positioning is achieved, easy to operate, and increased structural reliability.
