Application scenarios cover home offices, commercial displays, and other fields.

[0003] The display device bracket is a standard fixed display screen bracket, which typically consists of a base, a column, and a display screen connecting arm. The base provides support, the column adjusts the height, and the connecting arm adjusts the tilt and rotation angle of the display screen via a pivot or slide rail structure. The adjusted position is secured by fasteners such as bolts or clips, providing stable support for the display screen and enabling angle adjustment.

[0004] In current traditional display device bracket designs, the connection structure between the display device and the bracket is quite complex. When it is necessary to disassemble or install the display device, tools such as screwdrivers are often needed to complete the operation by tightening multiple screws, which is tedious and time-consuming. At the same time, the support base is mostly a fixed structure that cannot be folded and stored, and it occupies a lot of space when not in use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a foldable display screen bracket, which aims to improve the problems of cumbersome disassembly and assembly, the need for tools and base fixation, difficulty in storage, and large footprint in the prior art.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4The present invention provides an embodiment of a foldable display screen bracket, including a folding arm 1, a quick-release base 2 rotatably connected to the top of the folding arm 1, quick-release housings 3 fixedly connected to the left and right sides of the quick-release base 2, the quick-release base 2 and the quick-release housings 3 providing a connection carrier for the quick assembly and disassembly of the display device 5, a quick-release connecting seat 4 slidably connected to the inner wall of the quick-release housing 3, the display device 5 being threadedly connected to the front side of the quick-release connecting seat 4, and a rotatable base 6 rotatably connected to the bottom of the folding arm 1, with a folding support component provided at the bottom of the rotatable base 6;

[0035] The folding support assembly includes an X-shaped connecting frame 7, the top of which is rotatably connected to the bottom of the steering base 6. Multiple sliding protrusions 18 are fixedly connected to the inner side of the top of the X-shaped connecting frame 7, and multiple limiting sliders 19 are fixedly connected to the outer side of the bottom of the X-shaped connecting frame 7. A sliding groove 20 is provided at the bottom of the steering base 6. The top of the X-shaped connecting frame 7, through rotatable connection with the sliding protrusions 18 and the sliding groove 20, achieves rotation and sliding relative to the steering base 6. The sliding protrusions 18 are slidably connected inside the sliding groove 20. Limiting grooves 21 are provided on both the left and right sides of the top of the support frame 8, and the limiting sliders 19 are slidably connected inside the limiting grooves 21. Support frames 8 are slidably connected to both the left and right sides of the X-shaped connecting frame 7. Adjustable anti-slip pads 9 are threadedly connected to both the front and rear sides of the support frame 8. The support frame 8 provides a sliding track for the X-shaped connecting frame 7, and the stability of the support is enhanced by adjusting the anti-slip pads 9.

[0036] Reference Figure 1 , Figure 2 and Figure 5 A ball bearing 10 is slidably connected to the inner wall of the bottom of the quick-release housing 3. A fixing groove 14 is provided on the outer side of the quick-release connecting seat 4, and the outer side of the ball bearing 10 abuts against the inside of the fixing groove 14. A quick-release locking ring 11 is slidably connected to the outer wall of the quick-release housing 3. The quick-release locking ring 11 moves the fixing protrusion 16 by sliding, which, together with the ball bearing 10, realizes the locking and unlocking of the quick-release connecting seat 4. A locking ring spring 15 is fixedly connected to the quick-release locking ring 11 and the quick-release housing 3 on the opposite side. The locking ring spring 15 provides a return elastic force for the quick-release locking ring 11, so that the quick-release locking ring 11 can return to push the fixing protrusion 16 after being released. A fixing protrusion 16 is fixedly connected to the inner wall of the quick-release locking ring 11. The bottom abuts against the outside of the ball bearing 10. The fixed protrusion 16 is used to push the ball bearing 10 into the fixed groove 14, so as to lock the quick-release locking ring 11 against the quick-release connecting seat 4. The bottom of the quick-release housing 3 is provided with a sliding hole 17. The ball bearing 10 is slidably connected inside the sliding hole 17. The sliding hole 17 provides a sliding channel for the ball bearing 10 to slide. The quick-release housing 3 is slidably connected with a resistance slider 12. The inner wall of the resistance slider 12 is fitted with a resistance spring 13. The front end of the resistance slider 12 abuts against the rear side of the quick-release connecting seat 4. The resistance spring 13 applies elastic force to the quick-release connecting seat 4 through the resistance slider 12, so that the quick-release connecting seat 4 generates damping when sliding, which facilitates stable positioning.

[0037] Working principle: When the display device 5 is disassembled or assembled, pushing the quick-release locking ring 11 compresses the locking ring spring 15, causing the inner wall fixing protrusion 16 to disengage from the ball 10. The ball 10 then slides from the fixing groove 14 of the quick-release connecting seat 4 into the sliding hole 17 of the quick-release housing 3, releasing the lock. The quick-release connecting seat 4 slides smoothly under the damping action of the resistance slider 12 and the resistance spring 13, facilitating the disassembly and assembly of the display device 5. When the quick-release locking ring 11 is released, the locking ring spring 15 returns to its original position and pushes it to slide. The fixing protrusion 16 presses against the ball 10, causing it to engage in the fixing groove 14 to complete the lock and ensure the stable positioning of the display device 5.

[0038] When the bracket is folded or unfolded, the top of the X-shaped connecting frame 7 rotates around the steering base 6, and its top sliding protrusion 18 moves along the sliding groove 20 of the steering base 6. The bottom limiting slider 19 slides in the limiting groove 21 of the support frame 8, realizing the folding and extension of the X-shaped connecting frame 7. When folded, the support frame 8 moves closer to reduce space occupation. When unfolded, the X-shaped structure and the support frame 8 form a stable support. With the adjustment of the anti-slip pad 9, the friction is enhanced. The folding arm 1 can rotate, further improving the flexibility and space adaptability of the bracket.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
