[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a liquid crystal display screen anti-collision buffer frame structure includes a frame 2, an elastic plate 14 and a snap-fit ​​assembly; a liquid crystal display 1 is fixedly installed on the inner wall of the frame 2, and an expansion groove 3 is provided at the arc corner of the frame 2, with both ends of the expansion groove 3 extending to the two sides of the frame 2 respectively.

[0031] The elastic plate 14 is installed in the telescopic groove 3, and movable blocks 15 are fixedly connected to both ends of the elastic plate 14. By pushing the movable blocks 15 towards the corner of the frame 2, the movable blocks 15 squeeze the two ends of the elastic plate 14, causing the elastic plate 14 to bulge outward at the corner of the frame 2. Through the elastic force of the elastic plate 14, the corner of the LCD display 1 can be protected against impact. Under the action of the elastic force of the elastic plate 14, the elastic plate 14 can seal the telescopic groove 3, thereby ensuring the overall aesthetics of the frame 2.

[0032] The snap-fit ​​assembly is installed on the frame 2 and is used to fix the two ends of the elastic plate 14.

[0033] In this embodiment, as Figure 3 and Figure 6 As shown, a mounting groove 4 is provided on the corner side wall of the frame 2, and a sealing cover 5 can be detachably installed in the mounting groove 4;

[0034] The detachable design of the sealing cover 5 and the mounting groove 4 facilitates the replacement and maintenance of the structure inside the mounting groove 4, and also facilitates the assembly of the internal structure during the production process.

[0035] In this embodiment, as Figures 3-6 As shown, multiple card plates 9 are fixedly connected to the inner wall of the mounting groove 4. The outer wall of the card plate 9 protrudes to form a protrusion 10. The inner wall of the sealing cover 5 is fixedly connected to a connecting frame 11. The outer wall of the connecting frame 11 has a first card hole 12. The end of the connecting frame 11 has a slot 13. The card plate 9 is inserted into the inner wall of the slot 13, and the protrusion 10 is engaged with the first card hole 12.

[0036] The cooperation between the card plate 9 and the protrusion 10 enables quick assembly and disassembly as well as effective fixation.

[0037] In some embodiments, the mounting groove 4 can also be embedded with a permanent magnet array, and the sealing cover 5 adopts a composite structure of a magnetically conductive metal frame and a flexible sealing ring, which is fixed by magnetic attraction. The edge of the sealing cover 5 is provided with a magnetically conductive sheet that matches the polarity of the permanent magnet. When closed, it automatically attracts and aligns, so that the sealing cover 5 can be disassembled and assembled relatively easily.

[0038] In this embodiment, as Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, a first sliding hole 6 is provided on the opposite side of the frame 2 and the sealing cover 5. A sliding rod 16 is fixedly connected to the outer wall of the movable block 15. The end of the sliding rod 16 is slidably connected to the inner wall of the first sliding hole 6. The end of the sliding rod 16 passes through the first sliding hole 6 and extends into the mounting groove 4. A second locking hole 17 is provided on the outer wall of the end of the sliding rod 16 located in the mounting groove 4. A sliding groove 7 is provided on the opposite side of the frame 2 and the sealing cover 5. The sliding groove 7 is connected to the first sliding hole 6. A second sliding hole 8 is provided on the inner wall of the sliding groove 7 located on the sealing cover 5. A locking rod 19 is slidably connected to the inner wall of the sliding groove 7. The end of the locking rod 19 extends into the first sliding hole 6. A lever 21 is fixedly connected to the outer wall of the locking rod 19. When the lever 21 passes through the second sliding hole 8 and is slidably connected to it, a spring 22 is sleeved inside the sliding groove 7. One end of the spring 22 abuts against the inner wall of the sliding groove 7, and the other end of the spring 22 abuts against the end of the locking rod 19.

[0039] In this embodiment, as Figure 7 As shown, a rotatable ball 20 is embedded at one end of the lever 19 located in the first sliding hole 6, and the end of the lever 16 rolls into contact with the ball 20 when the lever 16 moves.

[0040] The ball bearing 20 and the end of the slide bar 16 use rolling friction, which can effectively reduce friction.

[0041] In this embodiment, as Figure 6 As shown, a limiting block 18 is fixedly connected to the inner wall of the expansion groove 3. The limiting block 18 is used to limit the movement of the movable block 15.

[0042] Working principle: When protection is needed, by pushing the movable block 15 to the corner of the frame 2, the movable block 15 squeezes the two ends of the elastic plate 14, causing the elastic plate 14 to bulge outward at the corner of the frame 2. Through the elasticity of the elastic plate 14, the corner of the LCD display 1 can be cushioned against impact.

[0043] The movable block 15 slides along the telescopic groove 3. The movable block 15 is limited by the limiting block 18. The movable block 15 drives the slide rod 16 to slide along the inner wall of the first sliding hole 6. The slide rod 16 squeezes the ball 20 at the end of the locking rod 19. At this time, under the elastic force of the spring 22, the locking rod 19 is inserted into the second locking hole 17 on the slide rod 16, thereby fixing the position of the movable block 15.

[0044] When storing, by pushing the lever 21 to slide along the inner wall of the second sliding hole 8, the lever 21 drives the locking rod 19 to slide along the inner wall of the sliding groove 7. The end of the locking rod 19 squeezes the spring 22, causing the locking rod 19 to move out of the second locking hole 17 on the sliding rod 16, thereby releasing the limitation on the movable block 15. At this time, under the elastic force of the elastic plate 14, the elastic plate 14 can seal the telescopic groove 3, thereby ensuring the overall aesthetics of the frame 2.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
