The adjustment component 6 is used to control the movement of the four engaging components 3, so as to separate or engage with the engaging components 3 in the adjacent display screens, so as to facilitate the installation of two adjacent display screens; It should be noted that when one device is installed, the four adjacent devices on the upper, lower, left and right sides can be engaged with the installed device through 3, so that the device does not need to be installed by screws, and the use of the mounting frame is also saved; In addition, four retracting components 7 cooperating with the engaging components 3 are movably installed at one end of the mounting plate 4 away from the display screen body 1. The four retracting components 7 are also arranged in a circular array with the center point of the fixing plate 2, and are used to control the retraction of the components in the engaging component 3, so that the device can be quickly disassembled and the device is easy to repair. A gear ring 8 is rotatably connected to the middle part of the end of the mounting plate 4 away from the display screen body 1. The gear ring 8 is used to make the four retracting components 7 operate synchronously. A positioning column 9 compatible with the adjusting component 6 is fixed at one end of the mounting plate 4 away from the display screen body 1, and the positioning column 9 is used to control the rotation angle of the components in the adjusting component 6.

[0017] Further, if Figure 4 As shown, the engaging component 3 includes a rack 30, four racks 30 are distributed in a ring array, the four racks 30 are parallel to the four sides of the fixing plate 2, the rack 30 is fixed to the end of the fixing plate 2 away from the display screen body 1, and an L block 31 is fixed to the clockwise end of the rack 30, as shown in FIG. Figure 4 As shown, one end of the four racks 30 in the clockwise direction is fixed with an L block 31, and one end of the concave part of the L block 31 away from the center of the fixed plate 2 is fixed with a telescopic assembly 32. The ends of the turning parts of the four L blocks 31 away from the center of the fixed plate 2 are all fixed with a telescopic assembly 32, and the four telescopic assemblies 32 are in a vertical state with the racks 30 on the same side; Among them, a slider 34 is slidably connected to the outer surface of the telescopic component 32. The telescopic component 32 includes a connecting rod and a spring. The telescopic component 32 is used to support the slider 34. A slide groove 33 adapted to the slider 34 is opened at one end of the L block 31 close to the rack 30. The slider 34 is located in the inner cavity of the slide groove 33 and can slide in the inner cavity of the slide groove 33. A clamping block 36 is fixed to the end of the slider 34 away from the telescopic component 32. The four clamping blocks 36 cooperate with each other in pairs, and two symmetrical clamping blocks 36 can be engaged with each other, so two adjacent devices can be engaged with each other using the clamping blocks 36. A push block 35 is fixed to the end of the slider 34 away from the fixed plate 2. By controlling the movement of the push block 35, the slider 34 can move with the clamping block 36.

[0018] Further, if Figure 5 and Figure 6 As shown, the adjusting component 6 includes a gear 60, which is rotatably connected to the fixing plate 2, and is located at an end of the fixing plate 2 away from the display screen body 1. The gear 60 is meshed with four racks 30, and the four racks 30 can be moved by rotating the gear 60, and the moving directions of the two symmetrical racks 30 are opposite. A fixing rod 61 is fixed to the end of the gear 60 away from the fixing plate 2, and the fixing rod 61 passes through the mounting plate 4 and is movably connected to the mounting plate 4; Next, a sliding ring 63 is slidably connected to the outer surface of the fixed rod 61. Two symmetrical connecting springs 67 are fixed to one end of the sliding ring 63 close to the fixed plate 2. The sliding ring 63 can slide on the outer surface of the fixed rod 61. The two connecting springs 67 are used to reset the sliding ring 63, and the sliding sliding ring 63 will not rotate on the surface of the sliding ring 63. Among them, a positioning plate 62 adapted to the positioning column 9 is fixed on the outer surface of the fixing rod 61. The positioning plate 62 is located on the outer surface of the fixing rod 61 and can rotate with the rotation of the fixing rod 61. The positioning column 9 is used to block the positioning plate 62, that is, to control the rotation angle of the fixing rod 61, so that the fixing rod 61 with the gear 60 rotates to control the moving distance of the four racks 30, so that the two symmetrical blocks 36 can be moved away from each other, that is, the two mutually engaged blocks 36 can be moved away from each other, which is convenient for installing and removing the device; In addition, two slots 64 are formed at one end of the sliding ring 63 away from the fixed plate 2, and the two slots 64 correspond to the positioning plate 62 and the positioning column 9 respectively. A rotating circular plate 65 is fixed at one end of the fixed rod 61 away from the fixed plate 2, and a positioning column 66 matching the slot 64 is fixed at one end of the rotating circular plate 65 close to the fixed plate 2. The positioning column 66 and the positioning plate 62 are in the same straight line. Rotating the rotating circular plate 65 can make the fixed rod 61 rotate with the gear 60, and the positioning column 66 can be inserted into the inner cavity of the slot 64, thereby preventing the fixed rod 61 from rotating. In the initial state, the locking column 66 and the positioning plate 62 are in the same straight line, and the locking column 66 is inserted into the inner cavity of the slot 64 corresponding to the positioning plate 62. By rotating the rotating circular plate 65, the locking column 66 can be inserted into the inner cavity of the slot 64 corresponding to the positioning column 9; Next, when the locking column 66 and the positioning plate 62 are in a vertical state, the locking block 36 between two adjacent display screens is in a locking state, such as Figure 8 As shown, the rotating circular plate 65 is rotated to make the positioning plate 62 contact the positioning column 9, and the positioning column 66 is inserted into the inner cavity of the card slot 64 corresponding to the positioning column 9. At this time, the card blocks 36 engaged between the two adjacent display screens are separated from each other, as shown in FIG. Fig. 9 shown.

[0019] Embodiment 2 This embodiment further defines the shrinking component 7 on the basis of the first embodiment, so as to facilitate the disassembly of the device.

[0020] Specifically, Figure 7As shown, the contraction component 7 includes a gear 2 70 and a fixing block 73. Four gears 2 70 are rotatably mounted in a ring array on one end of the mounting plate 4 away from the fixing plate 2. A matching plate 71 is fixed to the end of the gear 2 70 away from the mounting plate 4. The matching plate 71 is a shape of a circular plate and an arc plate spliced ​​together. An arc groove 72 is provided at the end of the matching plate 71 away from the gear 2 70. The gear 2 70 is adapted to the gear ring 8. The four gears 2 70 are meshed with the gear ring 8, and the four gears 2 70 can be rotated by the gear ring 8. Further, if Figure 7 As shown, one end of the fixed block 73 away from the same side gear 2 70 is fixed to the support spring 74, and one end of the support spring 74 away from the fixed block 73 is fixed with a sliding plate 75, and the sliding plate 75 is slidably connected with the mounting plate 4, and one end of the sliding plate 75 close to the same side engaging component 3 is fixed with an L-shaped plate 76, and the L-shaped plate 76 is adapted to the push block 35, and the concave part of the L-shaped plate 76 can push the corresponding push block 35, so that the push block 35 moves toward the side of the corresponding gear 2 70 in the inner cavity of the through groove 5, so that the four clamping blocks 36 are retracted between the fixed plate 2 and the mounting plate 4, so that the damaged display screen can be taken out easily; Among them, a matching column 77 that matches the arc groove 72 is fixed on one side of the L-shaped plate 76 that is away from the mounting plate 4 and close to the arc groove 72. Gear 2 70 drives the matching plate 71 to rotate, thereby rotating the arc groove 72. The rotation of the arc groove 72 causes the matching column 77 in its inner cavity to slide, so that the matching column 77 drives the push block 35 to slide with the L-shaped plate 76.

[0021] Specific implementation of the device: The device is a GOB-coated LED display screen. Through the cooperation between the provided snap-fit ​​component 3, the adjustment component 6 and the contraction component 7, the device can be easily installed and positioned, thereby improving the installation efficiency of the device. It is also convenient for the device to be disassembled and repaired, thereby improving the maintenance efficiency of the device. Specifically, the existing large display screen requires multiple display screen modules to be assembled. During assembly, the sliding ring 63 is pushed to compress the connecting spring 67, so that the sliding ring 63 and the rotating circular plate 65 are moved away from each other, and then the rotating circular plate 65 is rotated to make the positioning plate 62 contact the positioning column 9, so that the gear 1 60 moves with the four racks 30, and the racks 30 move with the connected L blocks 31, so that the slider 34 on the outer surface of the telescopic component 32 moves with the connected card blocks 36, so that the card blocks 36 between two adjacent display screen modules are moved away from each other. Figure 8 As shown, multiple display screen modules are assembled; Then, if Fig. 9As shown, after the installation is completed, the rotating circular plate 65 is rotated again to separate the positioning plate 62 from the positioning column 9, and the positioning plate 62 and the positioning column 66 are in the same straight line, and the positioning plate 62 is in a vertical state. Then, the card slot 64 is reset under the action of the connecting spring 67, so that the positioning column 66 can be inserted into the inner cavity of the card slot 64. At this time, the four racks 30 are reset under the action of the gear 1 60, and the card blocks 36 between the two adjacent display screen modules are engaged with each other, so that during installation, there is no need for positioning, and direct installation will not cause tilting. At the same time, there is no need to use too many screws for installation, which improves the installation efficiency of the device; During installation, you only need to connect the edge display screen modules to the steel structure frame, and there is no need to fix all the display screen modules with screws; Next, if the installed large display screen has a damaged display screen module, first, by rotating the rotating circular plate 65, the gear 1 60 rotates with the four racks 30, so that the four blocks 36 move and separate from the blocks 36 of the adjacent display screen module, and then, Fig.10 As shown, by rotating one of the matching plates 71, the gear 2 70 connected to the matching plate 71 rotates with the gear ring 8, so that the remaining gears 2 70 also rotate, thereby rotating the four matching plates 71, and the arc grooves 72 on the surfaces of the four matching plates 71 slide with the matching columns 77 in their inner cavities, so that the four L-shaped plates 76 move toward the center point of the fixed plate 2. At the same time, the push block 35 moves to the concave part of the L-shaped plate 76 under the action of the rack 30, and moves with the L-shaped plate 76 when the L-shaped plate 76 moves, so that the push block 35 moves with the slider 34 and the block 36 fixed by the slider 34 to the center of the fixed plate 2. The four blocks 36 shrink between the fixed plate 2 and the mounting plate 4, so that the device can be easily disassembled, which is convenient for maintenance of the device, and will not affect other display screen modules.
