[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a liquid crystal splicing screen that is easy to assemble and disassemble, including a display screen body 1, a frame 2 fixedly installed on the outer wall of the display screen body 1, and a quick-release component 3 and a fixing component 4 provided on the frame 2;

[0029] The quick-release assembly 3 includes a rack 33, a connecting rod 38 fixedly mounted at one end of the rack 33, a push rod 35 fixedly mounted at the other end of the connecting rod 38, a fixing plate 36 fixedly mounted on the outer wall of the push rod 35 and the rack 33, a first spring rod 37 fixedly mounted on the outer wall of the fixing plate 36, a slider 313 fixedly mounted on the side wall of the push rod 35 and the rack 33, a pin 32 fixedly mounted at the other end of the push rod 35 and the rack 33, a frame plate 39 fixedly mounted on the inner wall of the frame 2, a sliding groove 310 provided on the inner wall of the frame plate 39, a gear 34 rotatably mounted on the inner wall of the frame plate 39, a drive rod 311 fixedly mounted on the outer wall of the gear 34, a turntable 312 fixedly mounted at the other end of the drive rod 311, and an insertion hole 31 provided on the outer wall of the frame 2.

[0030] The other end of the first spring rod 37 is fixedly installed on the inner wall of the frame 2. The inner wall of the slide groove 310 is slidably connected to the slider 313. The gear 34 is meshed with the rack 33. The drive rod 311 passes through the through hole provided on the outer wall of the frame 2.

[0031] The specific implementation method is as follows: Rotate the turntable 312, and the turntable 312 drives the gear 34 to rotate through the drive rod 311. The gear 34 is meshed with the rack 33, so that the gear 34 rotates and drives the rack 33 to move horizontally. At the same time, the rack 33 moves and drives the push rod 35 to move through the connecting rod 38, so that the push rod 35 and the rack 33 move synchronously. The push rod 35 and the rack 33 synchronously drive the pin 32 to move out of the insertion hole 31 provided on the frame 2 of the other display screen body 1. The first spring rod 37 is simultaneously squeezed by the push rod 35 and the fixing plate 36 provided on the outer wall of the rack 33, so that it forms a compressed state.

[0032] The fixing component 4 includes a mounting sleeve 42, which is disposed on the outer wall of the frame 2. A rotating plate 47 is rotatably mounted on the inner wall of the mounting sleeve 42. A second spring rod 46 is fixedly mounted on the outer wall of the rotating plate 47. An integrated plate 44 is fixedly mounted on the other end of the second spring rod 46. A fixing block 45 is fixedly mounted on the other end of the integrated plate 44. A pull rod 43 is fixedly mounted on the outer wall of the integrated plate 44. An insertion hole 48 is provided on the outer wall of the frame 2. A fixing hole 41 is provided on the outer wall of the turntable 312.

[0033] The specific implementation method is as follows: First, pull the pull rod 43 horizontally. The pull rod 43 drives the integrated plate 44 to move. At the same time, the integrated plate 44 moves and drives the fixing block 45 to move out of the fixing hole 41 provided on the outer wall of the turntable 312. At the same time, one end of the second spring rod 46 is stretched, so that it is in a stretched state. Then, the integrated plate 44 is rotated 180 degrees by the pull rod 43. The pull rod 43 is released. Through the elastic force of the second spring rod 46, the integrated plate 44 is reset in the horizontal direction, and the fixing block 45 on the integrated plate 44 is aligned with the insertion hole 48, thus releasing the fixation of the turntable 312.

[0034] Working principle: First, pull the lever 43 horizontally. The lever 43 causes the integrated plate 44 to move. As the integrated plate 44 moves, the fixing block 45 moves out of the fixing hole 41 on the outer wall of the turntable 312. At the same time, one end of the second spring rod 46 is stretched, putting it into a stretched state. Then, the integrated plate 44 is rotated 180 degrees by the lever 43. The lever 43 is then released. Through the elastic force of the second spring rod 46, the integrated plate 44 is reset in the horizontal direction, aligning the fixing block 45 on the integrated plate 44 with the insertion hole 48. The turntable 312 is then released from its fixation. The turntable 312 is then rotated again. The turntable 312 drives the gear 34 to rotate through the drive rod 311. The gear 34 meshes with the rack 33. Next, the gear 34 rotates, causing the rack 33 to move horizontally. As the rack 33 moves, it drives the push rod 35 to move through the connecting rod 38, so that the push rod 35 and the rack 33 move synchronously. The push rod 35 and the rack 33 simultaneously drive the pin 32 to move out of the insertion hole 31 on the frame 2 of the other display screen body 1. The first spring rod 37 is simultaneously squeezed by the push rod 35 and the fixing plate 36 on the outer wall of the rack 33, so that it is in a compressed state. Similarly, the fixing block 45 on the integrated plate 44 is inserted into the fixing hole 41 on the outer wall of the turntable 312 again to fix the turntable 312 and prevent the pin 32 from resetting. This allows for quick assembly and disassembly of the LCD splicing screen.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
