DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1-5, the present utility model provides a technical solution: a narrow border structure of a liquid crystal display screen, including a first border 1, a second border 2, corner pieces 3 and a connecting device 4. The number of the first border 1 and the second border 2 is respectively set to two, the number of the corner pieces 3 is four, the corner pieces 3 are arranged between the first border 1 and the second border 2, the connecting device 4 is arranged on the surface of the corner pieces 3, and a protective device 5 is arranged on the surface of the corner pieces 3.

[0023] Next, specifically describe the specific settings and functions of its connecting device 4 and protective device 5.

[0024] Specifically, the connecting device 4 includes two clamping blocks 46. Two first chutes 43 and second chutes 44 are respectively opened on the surface of the corner piece 3. The two clamping blocks 46 are respectively slidably connected to the inner walls of the second chutes 44. Two pushing blocks 41 are slidably connected to the inner walls of the first chutes 43 on the surface of the corner piece 3. A pulling rope 47 is fixedly connected to the surface of the pushing block 41. The other end of the pulling rope 47 penetrates through the corner piece 3 and is fixedly connected to the surface of the clamping block 46. Slots 45 are opened on the surfaces of the first border 1 and the second border 2. The clamping block 46 is inserted into the inner wall of the slot 45. A positioning spring 48 is sleeved on the surface of the pulling rope 47. The two ends of the positioning spring 48 are respectively fixedly connected to the clamping block 46 and the inner wall of the second chute 44. An auxiliary component 42 is arranged on the surface of the pushing block 41.

[0025] In this implementation: during assembly, when aligning the corner piece 3 with the first border 1 and the second border 2, the positioning spring 48 can control the clamping block 46 to reset. The clamping block 46 drives the pushing block 41 to move together through the pulling rope 47, so that the clamping block 46 is inserted into the slots 45 on the surfaces of the first border 1 and the second border 2 to complete the assembly connection.

[0026] Specifically, the auxiliary component 42 includes a positioning block 421. A sliding groove is opened on the surface of the pushing block 41. The positioning block 421 is slidably connected to the inner wall of the sliding groove. Two positioning holes 423 are opened on the surface of the corner piece 3. The positioning holes 423 are communicated with the first chute 43. The positioning block 421 is inserted into the inner wall of the positioning hole 423. When the pushing block 41 moves the clamping block 46 out of the slot 45 on the surface of the first border 1 or the second border 2 through the pulling rope 47, the positioning block 421 can be inserted into the positioning hole 423 to limit the pushing block 41, facilitating subsequent assembly.

[0027] Specifically, two reset springs 422 are fixedly connected to one side of the positioning block 421 corresponding to the inner wall of the sliding groove on the surface of the pushing block 41.

[0028] In this implementation: the reset spring 422 can control the positioning block 421 to automatically reset and be inserted into the positioning hole 423, thereby improving the stability effect.

[0029] Specifically, the pushing block 41 is arranged in a convex shape.

[0030] Specifically, the protection device 5 includes elastic sleeves 51. There are four elastic sleeves 51, and the four elastic sleeves 51 are respectively arranged on one side of the corner piece 3. The elastic sleeves 51 are sleeved and connected with the corner piece 3. The elastic sleeves 51 can be sleeved on the corner piece 3, so as to realize the protection of the corners.

[0031] Specifically, elastic bands 52 are fixedly connected to the corresponding sides of the four elastic sleeves 51 respectively.

[0032] In this implementation scheme: The elastic bands 52 can play a role in tensioning, and at the same time, they can also protect the outer surfaces of the first frame 1 and the second frame 2.

[0033] Working principle: During assembly, the push block 41 can be pushed first. The push block 41 drives the latch block 46 to move through the pull rope 47, and the positioning spring 48 is stressed. When the push block 41 moves to a certain position, the return spring 422 releases elastic force, which can drive the positioning block 421 to return to its original position, so that the positioning block 421 is inserted into the positioning hole 423 on the surface of the corner piece 3. Then, the corner piece 3 can be aligned with the first frame 1 and the second frame 2. After splicing, the positioning block 421 can be pushed, and the return spring 422 is stressed, so that the positioning block 421 loses the restraint on the positioning hole 423. Then, the positioning spring 48 releases elastic force, pushes the latch block 46 to return to its original position, and the latch block 46 drives the push block 41 to return to its original position through the pull rope 47. Immediately, the two latch blocks 46 are respectively inserted into the card slots 45 on the surfaces of the first frame 1 and the second frame 2, and the assembly can be completed. After assembly, the elastic sleeves 51 can be sleeved on the corner piece 3 for protection. The four elastic bands 52 can be tightened, and at the same time, the elastic bands 52 can protect the outer sides of the first frame 1 and the second frame 2.
