[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A quick splicing connection structure for small-pitch screens includes a screen body 1. A U-shaped bracket 2 is fixedly connected to the back of the screen body 1 to support the screen body 1. A rubber pad 3 is fixedly connected to the outer side wall of the bracket 2 to increase the friction between the brackets 2 after splicing and enhance the fastness. A connecting block 5 is fixedly connected to the upper end of the bracket 2 to cooperate with the splicing groove to achieve splicing between screen bodies 1. The end of the connecting block 5 away from the bracket 2 is tapered to facilitate the insertion of the connecting block 5 into the splicing groove. The lower end of the bracket 2 is provided with a splicing groove corresponding to the connecting block 5.

[0022] In this embodiment, a sliding groove is provided on the outer side wall of the connecting block 5, and a wedge-shaped limiting block 9 is slidably inserted on the inner side wall of the sliding groove to prevent the connecting block 5 from loosening. A guide block 8 is fixedly connected to the upper side wall of the limiting block 9 to guide the movement of the limiting block 9 in conjunction with the guide groove. A guide groove corresponding to the guide block 8 is provided at the inner top of the sliding groove. The end of the guide block 8 away from the limiting block 9 slides into the guide groove. An arc-shaped groove is provided on the side of the guide block 8 away from the limiting block 9. A ball is rolled on the inner side wall of the arc-shaped groove to reduce the resistance when the guide block 8 moves. The ball passes through the arc-shaped groove. A groove is provided at the end of the limiting block 9 away from the spring 6. A first magnet 10 is fixedly embedded in the inner bottom of the groove to magnetically attract and prevent loosening of the limiting block 9 in conjunction with the second magnet. A second magnet attracted to the first magnet 10 is fixedly connected to the inner side wall of the splicing groove.

[0023] In this embodiment, one end of the limiting block 9 slides through the slide groove, and the other end of the limiting block 9 is fixedly connected to a spring 6 for providing elastic support to the limiting block 9. The end of the spring 6 away from the limiting block 9 is fixedly connected to the inner wall of the slide groove. A wire ring 7 is fixedly connected to the inner wall of the slide groove away from the limiting block 9 for guiding the movement of the pull rope 11. The inner top of the bracket 2 is provided with a circular connecting groove, and a hollow groove is provided between the inner top of the connecting groove and the inner bottom of the slide groove. The end of the limiting block 9 facing the spring 6 is fixedly connected to the pull rope 11 for driving the limiting block. 9. The pull rope 11 is made of nylon to improve its strength. The end of the pull rope 11 away from the limit block 9 slides through the guide ring 7, the hollow groove and the connecting groove in sequence and is fixedly connected to the pull ring 4 to drive the pull rope 11 to move. A rubber strip 13 is fixedly connected to the inner side wall of the pull ring 4 to improve the comfort of using the pull ring 4. A vertically set connecting cylinder 12 is fixedly connected to the upper end of the pull ring 4 to cooperate with the connecting groove to prevent the pull ring 4 from loosening. An external thread is fixed on the outer side wall of the connecting cylinder 12 and an internal thread that meshes with the external thread is fixed on the inner side wall of the connecting groove.

[0024] In this embodiment, when splicing the screen 1, the connecting block 5 is inserted into the splicing groove, with its insertion end abutting against the wedge-shaped surface of the limiting block 9. At this time, the connecting block 5 pushes the limiting block 9 to slide and retract along the groove. When the connecting block 5 is fully inserted into the splicing groove, the spring 6 drives the limiting block 9 to reset by elastic potential energy, so that it is embedded in the limiting groove, realizing the mechanical locking of the connecting block 5, effectively preventing the screen 1 from loosening after splicing. At the same time, the magnetic attraction between the first magnet 10 and the second magnet further enhances the stability of the limiting block 9. If it is necessary to disassemble the screen, pull the pull ring 4 to drive the pull rope 11 to pull the limiting block 9 away from the limiting groove, releasing the locked state, and the connecting block 5 can be pulled out from the splicing groove. At the same time, through the thread engagement principle, the connecting cylinder 12 can be screwed into the connecting groove to fix the pull ring 4 and prevent loosening. After unscrewing the connecting cylinder 12, the pull ring 4 can resume normal operation.

[0025] 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.
