Detailed Implementation

[0023] 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.

[0024] See Figures 1-5 This utility model provides two technical solutions:

[0025] First embodiment: An assembly device for LCD splicing screens, including a fixing frame 1, a plurality of display screen units 4 are movably mounted on the front side of the fixing frame 1, and further including:

[0026] Adjustment component 2 is set inside the fixed frame 1 for adjusting the position of several display screen units 4. Adjustment component 2 includes a fixed plate 21 fixedly installed inside the fixed frame 1. The front side of the fixed plate 21 has four movable slots 23, and the four movable slots 23 are all installed at an angle. The cross section of the four movable slots 23 is cross-shaped. Movable plates 22 are slidably installed inside the four movable slots 23. The fixed frame 1 is provided with a limit component to fix the position of the movable plates 22.

[0027] The mounting component 3 is located on the rear side of the display unit 4 for easy installation and fixation of the display unit 4. The limiting component includes connecting plates 25 movably installed on the left and right sides of the inner cavity of the fixing frame 1, and the cross-section of the connecting plates 25 is convex. The top and bottom surfaces of the inner cavity of the fixing frame 1 are provided with limiting grooves 27 to limit the movement trajectory of the connecting plates 25. The inside of the fixing frame 1 is movably installed with a positive and negative threaded screw 26 for adjusting the position of the connecting plates 25. The rear side of the movable plate 22 is fixedly installed with a slotted plate 24. The top and bottom surfaces of the connecting plates 25 are slidably installed inside the limiting grooves 27. The left end of the positive and negative threaded screw 26 movably passes through the inside of the fixing frame 1 and extends to the left side of the fixing frame 1. The right end of the positive and negative threaded screw 26 is threaded through the left side of the connecting plate 25 and movably installed on the right side of the inner cavity of the fixing frame 1. The opposite side of the connecting plates 25 is slidably installed on one side of the slotted plate 24. Rotating the positive and negative threaded screw 26 can drive the connecting plates 25 to move to the opposite side and drive the slotted plate 24 to move towards the center point.

[0028] The movable plate 22 and connecting plate 25 allow for convenient simultaneous adjustment of the position of the display unit 4 for splicing. In use, rotating the positive and negative screws 26 moves the connecting plate 25 to the opposite side. Then, the connecting plate 25 moves the slot plate 24 towards the center point of the fixed plate 21. At the same time, the slot plate 24 moves the movable plate 22 through the mounting component 3 to move the display unit 4 synchronously. When the display unit 4 reaches the appropriate position, stopping the rotation of the positive and negative screws 26 will fix the position of the display unit 4 and complete the splicing. This is convenient, quick, and reduces the difficulty of operation.

[0029] The second embodiment differs from the first embodiment in that: the mounting assembly 3 includes an insert plate 33 fixedly mounted on the rear side of several display screen units 4; a mounting plate 31 is fixedly mounted on the front side of the movable plate 22; a slot 32 is provided on the front side of the mounting plate 31; a snap-fit ​​assembly is provided inside the insert plate 33 to fix the position of the insert plate 33; the top surface of the slot 32 penetrates the interior of the mounting plate 31 and extends to the top surface of the mounting plate 31; the rear side of the insert plate 33 is movably mounted inside the slot 32; and the limiting assembly includes a slot 35 formed on the top surface of the insert plate 33, and the slot 35 is movably mounted inside the slot. There is a vertical plate 34 with a convex cross-section. Several springs 36 are fixedly installed on the opposite side of the vertical plate 34. A locking block 37 for fixing the position of the insert plate 33 is fixedly installed on the bottom surface of the vertical plate 34 away from the several springs 36. The slot 32 has slots 38 on both the left and right sides. The top surface of the slot 32 penetrates the interior of the mounting plate 31 and extends to the top surface of the mounting plate 31. One side of the locking block 37 moves through the interior of the slot 35 and extends into the interior of the slot 38. The spring force of the several springs 36 can drive the vertical plate 34 to insert the locking block 37 into the interior of the slot 38 and fix the position of the insert plate 33.

[0030] The installation and fixing of the display unit 4 is convenient through the insertion plate 33 and the locking block 37. When in use, pinch the vertical plate 34 to move it to the center and put the locking block 37 into the slot 35. Then pick up the display unit 4, put the insertion plate 33 into the slot 32, and then release the vertical plate 34. At this time, the elastic force of the spring 36 will drive the vertical plate 34 to insert the locking block 37 into the slot 38 to fix the position of the insertion plate 33, thereby fixing the position of the display unit 4. It is convenient, quick and easy and has good practicality.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user pinches the vertical plate 34 to move it towards the center, allowing the locking block 37 to be inserted into the slot 35. Then, the user picks up the display unit 4 and inserts the insert plate 33 into the slot 32. The user then releases the vertical plate 34. At this point, the spring force of the spring 36 will cause the vertical plate 34 to insert the locking block 37 into the slot 38, fixing the position of the insert plate 33. This fixes the position of the display unit 4. Then, the user rotates the positive and negative screws 26 to move the connecting plate 25 to the opposite side. The connecting plate 25 will then move the slot plate 24 towards the center point of the fixing plate 21. At the same time, the slot plate 24 will move the movable plate 22 through the mounting component 3 to move the display unit 4 synchronously. When the display unit 4 reaches the appropriate position, the user stops rotating the positive and negative screws 26 to fix the position of the display unit 4 and complete the splicing.
