Specific embodiments

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a spliced LED display screen, including a display screen body 1 for use, and a middle clamping rail 2 provided on an external fixing component, and upper and lower fixed sliding rails 3 are installed on both sides of the middle clamping rail 2. The lengths of the upper and lower fixed sliding rails 3 of the middle clamping rail 2 can be set according to the number of display screen bodies 1 to be assembled, so that the display screen body 1 can be assembled and fixed. And moving sliding grooves 4 penetrating both sides are provided inside the middle clamping rail 2 and the upper and lower fixed sliding rails 3. The penetration on both sides facilitates the left - right pushing and disassembly of the display screen body 1, making the disassembly more convenient. Slots 7 are provided outside the moving sliding grooves 4 to facilitate the movement of the upper and lower fixed sliders 9 and the middle slider 10, and to prevent the upper and lower fixed sliders 9 and the middle slider from being pulled outwards. A penetrating bayonet 8 is provided inside the middle clamping rail 2, and the bayonet 8 can be set in a rectangular shape to have a larger stress area and better fixing effect. And a plurality of heightening columns 5 are provided on the inner sides of the middle clamping rail 2 and the upper and lower fixed sliding rails 3. Under the action of the heightening columns 5, there is a gap between the middle clamping rail 2 and the upper and lower fixed sliding rails 3 and the external wall, which is convenient for the staff to reach in and press the clamping block 11 for convenient disassembly. And through - holes 6 are provided in the heightening columns 5 on both sides, and through the fixing holes 6, the middle clamping rail 2 and the upper and lower fixed sliding rails 3 can be fixed on an external wall or the like.

[0028] On the upper and lower ends of the rear end face of the display screen body 1, there are upper and lower fixing sliders 9 which are slidably connected to the moving chute 4 inside the upper and lower fixing slide rails 3 through the slots 7. Through the sliding connection between the upper and lower fixing sliders 9 and the upper and lower fixing slide rails 3, the display screen body 1 can be fixed up and down, so that the display screen body 1 can only move left and right and cannot move up and down. In the middle of the rear end face of the display screen body 1, there is a middle slider 10. Inside the middle slider 10, there is a pressing cavity penetrating one side, and a clamping block 11 is connected to the inside of the pressing cavity through a spring 12. When the clamping block 11 passes through the bayonet 8, under the elastic force of the spring 12, the clamping block 11 is ejected into the bayonet 8 for fixation, so as to realize the left and right fixation of the display screen body 1, and thus assemble the display screen body 1, making the assembly efficiency higher and faster and saving working time.

[0029] Preferably, the distance between two adjacent bayonets 8 is the same as the distance between two adjacent clamping blocks 11 on the outer side of the display screen body 1. In this way, when the display screen body 1 is assembled, the sides are close to each other, avoiding a large gap between the display screen bodies 1 and making the assembly effect better. There is a protruding part around the outer circle of the inner side of the clamping block 11, and the area size of the protruding part is larger than the area size of the bayonet 8, so as to prevent the clamping block 11 from being completely ejected, facilitating the stable effect and the compression work. The outer side edge of the clamping block 11 is set in a chamfer shape, making it convenient for the clamping block 11 to be compressed to both sides and facilitating the disassembly work.

[0030] Working principle: When in use, first, according to the number of all assembled display screen bodies 1, fix the corresponding middle clamping rails 2 and upper and lower fixing slide rails 3 to an external fixing bracket such as a wall. Then, insert the upper and lower fixing sliders 9 and the middle slider 10 on the outer side of the display screen body 1 into the moving chute 4 inside the upper and lower fixing slide rails 3 and the middle clamping rails 2 correspondingly. When the clamping block 11 slides in the moving chute 4 and passes through the bayonet 8, under the elastic force of the spring 12, the clamping block 11 is pushed into the bayonet 8 for fixation. And according to the number to be inserted, the clamping block 11 can be pressed to adjust the position of different inserted bayonets 8, facilitating the assembly of the display screen body 1. And when disassembling, as long as the clamping block 11 is pressed to move the display screen body 1, the disassembly work can be realized, thus completing the work.

[0031] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
