By the way, our lives are now entering an information era in which the electronics industry is developing vigorously. Various multimedia electronic products are rapidly introducing new ones, which has indeed brought more options to the development of human entertainment and leisure. With the continuous R&D and advancement of technology, whether the practicality and convenience of related electronic products meet the needs of users, or whether they are more in line with the purpose of creating benefits and saving costs, are topics of great concern to consumers.

At present, as consumers understanding and acceptance of liquid crystal displays are gradually increasing, the price of liquid crystal displays is becoming more and more popular. Compared with traditional computer monitors (CRT), liquid crystal displays take up less space and their appearance. More exquisite, making LCDs widely used by consumers, so LCDs will become the first choice for display interfaces such as computers and TVs in the future, and it is said that from the future mainstream home appliance manufacturers in the world have turned their main focus to LCD TV, it may become another popular product in the world after DVD.

However, consumers still have inconveniences when viewing and using liquid crystal displays. For example, when viewing liquid crystal displays, due to personal viewing habits and height dimensions, or the users background light source reflects light, the LCD screen often Need to adjust its pitch angle.

Regarding the conventional liquid crystal display, please refer to Figure 1. A screen 1 is provided. The back of the screen 1 is provided with a pivoting part 3 which is pivotally connected to a supporting frame 2 so that The screen 1 can be rotated up and down, and the support frame 2 includes a base 4 that is placed on a flat surface (such as a desktop). In order to make the positioning of the tilt angle of the screen 1 more stable and not easy to move, the pivoting portion 3 is usually performed in a relatively tight manner when pivoting the screen 1 and the support frame 2. Therefore, the liquid crystal display is When adjusting screen 1, it is often necessary to hold the screen 1 with both hands and use one hand to adjust the tilt angle, and hold the base 4 with one hand so that it does not shake during the angle adjustment process to complete the adjustment of the screen 1. If the user When performing other actions that cannot free their hands (such as answering a phone or eating), the user must free both hands before adjusting the screen 1, which will cause inconvenience for the user. Therefore, how to develop a flat-panel display telescopic angle adjustment frame that can be adjusted with one hand to solve the above-mentioned problems has become an important issue to be solved urgently.

In view of this, in order to improve the shortcomings of conventional use, the inventor finally developed and designed a telescopic angle adjustment frame of the flat display device that can be adjusted by one hand after a long period of hard research and experimentation.

One purpose of this creation is to provide a telescopic angle adjustment frame of a flat display device that can be adjusted with one hand. The frame is composed of a fixed frame, a sliding frame and a supporting leg. The fixed frame is combined with a body to make The fixing frame can drive the body to move together. The supporting foot is arranged at the bottom end of the sliding frame. An elastic element is provided between the fixing frame and the sliding frame to connect the fixing frame and the sliding frame. The supporting foot protrudes out of the body, or when the supporting foot receives an external force, the supporting foot can be moved into the body, and after the external force is released, the adjustment frame and the body will quickly form a force balance The state maintains an included angle between the supporting foot and the main body.

In order to facilitate your reviewer to have a further understanding and understanding of the purpose, shape, features and effects of the structure and device of this creation, the examples and diagrams are described in detail as follows:

This creation is a telescopic angle adjustment frame of a flat display device that can be adjusted with one hand. Please refer to Figures 2, 4, and 5. The adjustment frame 10 includes a fixing frame 100, a sliding frame 200, and a supporting leg 400. One end of the supporting leg 400 is arranged at one end of the sliding frame 200, and the other end of the supporting leg 400 can be placed on a flat surface 500 (such as a desktop). One surface of the fixing frame 100 is combined with a body 600 to make the fixing frame 100 can drive the main body 600 to move together. A part of the sliding frame 200 can be assembled on the fixing frame 100 and the moving range is restricted by the fixing frame 100. The fixing frame 100 and the sliding frame 200 are connected to each other. It is connected by an elastic element 300 that can be elastically stretched. When the main body 600 receives an external force as shown in Figure 5, the supporting foot 400 will retract into the main body 600 due to the reaction force of the plane 500, and drive the sliding frame 200 to elastically contract the elastic element 300 , And pause after reaching a specific position. At this time, between the adjusting frame 10 and the main body 600, a force balance state of elastic force and gravity balance will be quickly formed, so that the supporting foot 400 and the main body 600 are maintained at a specific Tilt angle. When the adjusting frame 10 or the main body 600 is subjected to an external force as shown in Figure 4 and the force balance is broken, the supporting foot 400 will extend downward due to gravity and drive the elastic element 300 to stretch And gradually increase the inclination angle of the main body 600 until the sliding frame 200 is restricted by the fixed frame 100 to move, or the adjustment frame 10 and the main body 600 are restored to a force balance state, the sliding frame 200 stops moving.

In this embodiment, please refer to Figure 2, where the sliding frame 200 faces the fixing frame 100 and has a placement groove 210, so that one end of the elastic element 300 can be connected to the placement groove 210. The two ends of the sliding frame 200 are respectively provided with a guard plate 220 protruding toward the fixing frame 100, so that the guard plate 220 forms a sliding groove 222 on the inner surface of the two ends of the sliding frame 200, and the lower part of the sliding frame 200 is close to A plurality of first perforations 111 are provided at the two edges. A plurality of second perforations 401 matching the first perforations 111 are provided on one side of the supporting leg 400. The bolt 113 is fixed so that the supporting leg 400 is locked on a surface of the sliding frame 200, so that the supporting leg 400 and the sliding frame 200 are integrated and move in the same direction.

In one of the best embodiments of this creation, please refer to Figures 2 and 4 again. The fixing frame 100 includes a frame 110 with a central portion recessed, and two ends of the frame 110 are respectively provided with outwardly extending A plate body 221. The two plate bodies 221 are connected with one surface of the body 600 to drive the body 600 to move in the same direction with the fixing frame 100. The frame 110 is provided with a plurality of third through holes 223, which can pass through the The third through hole 223 uses a plurality of second fixing bolts 225 on the side of the frame 110 facing the sliding frame 200 to respectively lock the two buffer portions 114 in sequence, so that the buffer portion 114 is inserted into the sliding groove 222 and the The sliding groove 222 can move along the buffer portion 114. In this way, between the fixed frame 100 and the sliding frame 200, the buffer portion 114 can provide dynamic friction and static friction. When there is displacement between the sliding frame 200, the restoring force of the elastic element 300 is relaxed to reduce the moving speed of the supporting foot 400, and the static friction force is related to the elastic force of the elastic element 300 of the adjusting frame 10 and the main body 600 When a force balance state is formed between the gravity, a force is provided that the fixed frame 100 and the sliding frame 200 no longer move.

In this embodiment, please refer to Figures 2 and 3 again. The buffer portion 114 is composed of a U-shaped block 115 and a clamping block 120. The concave portion of the U-shaped block 115 forms a container. The accommodating space can accommodate the clamping block 120, so that the U-shaped block 115 can be fixed between the clamping blocks 120 and the fixing frame 100, and the U-shaped block 115 is embedded in the sliding groove 222 , Because the U-shaped block 115 can be a material with a relatively high friction coefficient (such as plastic or rubber), one side of the U-shaped block 115 abuts the surface of the sliding groove 222, causing friction to ease the U-shaped block 115 in the The chute 222 moves too fast and causes the inconvenience of angle adjustment; when the chute 222 moves along the U-shaped block 115, the chute 222 must first overcome the maximum static friction with the U-shaped block 115, and the friction of different materials The frictional force produced by the coefficient is different. The friction coefficient ranges from 0 to 1. The larger the value, the greater the frictional force, and vice versa, the smaller the frictional force. After the adjustment frame 10 and the main body 600 (see Figure 4) are in a force balance state, they will not be damaged due to a very small external force.

In another embodiment of the present creation, please refer to Figure 2 again. The elastic element 300 is a curled reed and has a restoring elastic force that can return to the original curled shape after being straightened outwards. When the reed is forced to straighten After the external force disappears, the resilient force of the elastic element 300 will drive itself back to its original shape (curled shape). One end of the elastic element 300 is locked on the fixing frame 100, and the other end is hollow in the roll, and the elastic element 300 300 are respectively installed with two bushes 310 on the two sides of the other end, and a shaft 320 is penetrated between the two bushes 310, so that both ends of the shaft 320 can be restored to the original curled elastic force by the elastic element 300. A groove 211 is fixed at both ends of the placing groove 210, so that the elastic element 300 can be elastically rolled at the position of the placing groove 210 to connect and drive the fixing frame 100 and the sliding frame 200. In this way, when the supporting foot 400 or the main body 600 receives an external force as shown in Figure 5, the supporting foot 400 will retract upward into the main body 600 due to the reaction force of the plane 500 and simultaneously drive the The sliding frame 200 makes the elastic element 300 curl back to its original shape, and if it stops after reaching a specific position, the adjustment frame 10 and the main body 600 will quickly form a state of elastic force and gravity balance and maintain a specific tilt angle .

Please refer to Figure 2, in order to prevent the elastic element 300 from recovering excessively, a movable block 130 can be provided on both sides of the fixing frame 100, so that the sliding groove 222 can be blocked along the U-shaped block. 115 moves down excessively, deviating from the original path.

In this creation, the main body 600 can be a screen. Please refer to Figures 4 and 5. If the user wants to adjust the tilt angle of the screen, he presses the screen vertically down as shown in Figure 5. At this time, the static friction force between the sliding groove 222 and the buffer portion 114 (see Figure 2) disappears, and the force balance is broken. The supporting foot 400 receives the reaction force of the plane 500 and retracts into the body 600, and Drive the elastic element 300 to elastically contract and stop after reaching the required inclination angle. At this time, the elastic force (elastic contraction force) of the elastic element 300 and the gravity of the body 600 will quickly reach a force balance without displacement; or The upper end of the main body 600 is pushed by force as shown in Fig. 4. At this time, the supporting foot 400 will move down toward the plane 500 due to gravity and drive the elastic element 300 to elastically stretch and reach the required inclination angle After a pause, at this time, the elastic force (elastic stretching force) of the elastic element 300 and the gravity of the body 600 will quickly reach a force balance and no longer displacement. With the above-mentioned operation method, the operation method is quite easy. It does not require too much effort to operate the adjustment frame 10 with one hand; until the user is satisfied with the angle, immediately stop the adjustment of the screen to make When the aforementioned force balance state is reached, the operation of adjusting the angle of the screen is completed.

According to, the above are only the preferred specific examples of this creation, but the structural features of this creation are not limited to this.
