Detailed Implementation

[0019] 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.

[0020] Example: Please see Figure 1 - Figure 5 This embodiment of a fast-aligning full-color LED screen splicing device includes a workbench 1. The top of the workbench 1 is provided with a plurality of sliding grooves 2, which are arranged in a circular array. A slider 3 is slidably connected inside the sliding groove 2. A connecting block 4 is fixedly connected to the top of the slider 3. The workbench 1 is provided with an anti-collision mechanism through the connecting block 4. A connecting rod 16 is fixedly connected to the bottom of the slider 3. A transmission component is provided on the slider 3 through the connecting rod 16. The anti-collision mechanism includes at least two hollow rods 5 arranged on the adjacent sides of the connecting block 4. The hollow rods 5 are equipped with displacement rods 6 inside, and ball heads 7 are provided at the ends of the displacement rods 6. Several limiting holes 8 are opened on the sides of both the hollow rods 5 and the displacement rods 6. The transmission assembly includes a second connecting rod 17 disposed below the first connecting rod 16, and a third connecting rod 18 disposed below the second connecting rod 17; Before splicing the screen body 15, firstly, pull the slider 11 away from the limiting hole 8. Then, pull the displacement rod 6 to slide within the hollow rod 5, making the ball head 7 parallel to the side of the screen body 15 to be spliced. Next, release the slider 11; under the action of the anti-collision mechanism, the slider 11 will enter the limiting hole 8, fixing the position between the displacement rod 6 and the hollow rod 5. Following this method, adjust the position of the ball head 7 on the adjacent side so that it is parallel to the other side of the screen body 15 to be spliced. Finally, activate the electric telescopic rod 20 to move the stop. As plate 19 moves downward, under the action of the transmission component, multiple sliders 3 will drive multiple screen bodies 15 to move closer to each other, so that multiple screen bodies 15 are spliced ​​into a large screen. At this time, when two adjacent screen bodies 15 come into contact, the two ball heads 7 will also come into contact simultaneously. After the two ball heads 7 come into contact, the two screen bodies 15 will not continue to move closer. That is, the two screen bodies 15 will not collide due to excessive force or misjudgment of distance, thus avoiding damage to the screen bodies 15 during the splicing process and improving the service life of the screen bodies 15. At this time, collisions between screen bodies 15 during splicing are avoided, allowing screen bodies 15 to be spliced ​​quickly and smoothly. There is no need to worry about two or more screen bodies 15 colliding due to misjudgment of distance, thus improving the service life of screen bodies 15.

[0021] The anti-collision mechanism also includes a sleeve 9 disposed on the side of the hollow rod 5, a piston 10 disposed inside the sleeve 9, a slide rod 11 disposed on the side of the sleeve 9, a spring 12 disposed inside the sleeve 9, a connecting plate 13 disposed on the top of the connecting block 4, a concave connecting plate 14 disposed above the connecting plate 13, and a screen body 15 disposed above the concave connecting plate 14. One end of the hollow rod 5 is fixedly connected to the side of the connecting block 4. Hollow rods 5 are provided on the side of the two connecting blocks 4 that are close to each other. The displacement rod 6 is slidably connected to the hollow rod 5. One end of the displacement rod 6 passes through the other end of the hollow rod 5. The limiting hole 8 on the displacement rod 6 is adapted to the limiting hole 8 on the hollow rod 5. The ball head 7 is fixedly connected to one end of the displacement rod 6. One end of the sleeve 9 is fixedly connected to the side of the hollow rod 5. The sleeve 9 and the limiting hole 8 on the hollow rod 5 are concentric. The piston 10 is slidably connected to the sleeve 9. One end of the slide rod 11 passes through the sleeve 9. The slide rod 11 is slidably connected to the sleeve 9. One end of the slide rod 11 passes through the piston 10 and is fixedly connected to the piston 10. One end of the slide rod 11 extends into the limiting hole 8 and is slidably connected to the limiting hole 8. The spring 12 is sleeved on the outer wall of the slide rod 11. One end of the spring 12 is fixedly connected to the inner wall of the sleeve 9, and the other end of the spring 12 is fixedly connected to the side of the piston 10. The top of the connecting block 4 is fixedly connected to the bottom of the connecting plate 13. The top of the connecting plate 13 is fastened to the bottom of the concave connecting plate 14. The top of the concave connecting plate 14 is fixedly connected to the bottom of the screen body 15. Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 Before splicing the screen body 15, firstly, align the concave connecting plate 14 at the bottom of the screen body 15 with the connecting plate 13, and then fasten the concave connecting plate 14 to the connecting plate 13 with bolts. The fixing position can be found in [the relevant documentation]. Figure 3Furthermore, this fixing method is a well-known and mature technology in the art, and therefore will not be described in detail in this embodiment. After fixing the concave connecting plate 14 onto the connecting plate 13, that is, fixing the screen body 15 onto the connecting block 4, the slide rod 11 is pulled to move it away from the limiting hole 8 on the hollow rod 5 and the displacement rod 6. At this time, as the slide rod 11 moves, the piston 10 will also slide within the sleeve 9. As the piston 10 moves, the spring 12 will gradually be in a compressed state. After the slide rod 11 leaves the limiting hole 8, the displacement rod 6 can be pulled to slide within the hollow rod 5. When the displacement rod 6 moves, the ball head 7 will also move with it, making the ball head 7 parallel to the side of the screen body 15 that needs to be spliced. Then, the slide rod 11 is released. At this time, the spring 12 loses its tension and will begin to reset. At this time, as the spring 12 returns to its original position, the piston 10 will drive the slide rod 11 to slide until the slide rod 11 is engaged in the limiting hole 8, thus fixing the position of the ball head 7. Then, following this method, adjust the position of the ball head 7 on the adjacent side so that it is parallel to the other side of the screen body 15 that needs to be spliced. When two or more screen bodies 15 approach each other and are spliced, the two ball heads 7 will contact each other simultaneously as the sides of the two screen bodies 15 come into contact. At this time, under the action of the contact of the two ball heads 7, the two screen bodies 15 will not approach each other due to the force, and will only splice without collision. Moreover, the position of the ball heads 7 on the adjacent sides can be adjusted, and even if the lengths of the adjacent sides of the screen body 15 are different, they can be adjusted accordingly, further improving the flexibility of the device. At this time, collisions are prevented from occurring during the splicing process of the screen body 15, improving the stability of the device. In addition, the position of the ball head 7 can be changed according to the length of the screen body 15, so that screen bodies 15 of different sizes can be adapted to the device, improving the flexibility of the device.

[0022] The transmission assembly also includes a baffle 19 at the bottom of the connecting rod 18, an electric telescopic rod 20 inside the worktable 1, the bottom of the slider 3 is fixedly connected to the top of the connecting rod 16, and the bottom of the connecting rod 16 is hinged to the top of the connecting rod 27. The top of connecting rod 3 18 is hinged to the bottom of connecting rod 2 17, the bottom of connecting rod 3 18 is fixedly connected to the top of baffle 19, the bottom of electric telescopic rod 20 is fixedly connected to the inner bottom wall of workbench 1, and the bottom of baffle 19 is fixedly connected to the output end of electric telescopic rod 20. Please refer to Figure 2 and Figure 4When splicing multiple screen bodies 15, firstly, the electric telescopic rod 20 is activated to drive the baffle 19 to move downward. At this time, as the baffle 19 moves downward, the angle between the connecting rod 3 18 and the connecting rod 2 17 will change and become larger and larger. The angle between the connecting rod 2 17 and the connecting rod 1 16 will also change and become larger and larger. At this time, under the limiting effect of the slide groove 2 on the slider 3, multiple sliders 3 will drive multiple screen bodies 15 to move closer to each other until the splicing is completed. At this point, the multiple screen bodies 15 are automatically spliced ​​together without the need for manual splicing, which improves the convenience of the device. In addition, with the anti-collision mechanism, there is no need to worry about collisions between the screen bodies 15.
