[0016] 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a dustproof LED display screen, including a display screen body 1. A wiring groove 101 is provided at the bottom of the back of the display screen body 1. Sliding cavities 102 are provided on both inner side walls of the wiring groove 101. Sliding rods 11 are slidably connected to the inner walls of the two sliding cavities 102. Baffle plates 12 are fixedly connected to the outer walls of the two sliding rods 11, and the baffle plates 12 extend through the sliding cavities 102 into the wiring groove 101. A rectangular groove 103 is provided at the top of the wiring groove 101, and the rectangular groove 103 communicates with the two sliding cavities 102. The top of one baffle plate 12 is fixedly connected to a first toothed plate 13 arranged in an L-shape, and the other baffle plate... A second rack plate 14, arranged in an L-shape, is fixedly connected to the top of the 12. Several soft baffles 15 are fixedly connected to the two baffles 12 near the wiring groove 101. A connecting box 2 is fixedly connected to the outer wall of the back of the display body 1 near the upper end of the wiring groove 101. A worm gear 21 is rotatably connected through the connecting box 2, and the worm gear 21 extends from the top of the connecting box 2 to the outer end. A rotating rod 23 is rotatably connected between the inner side wall of the connecting box 2 and the rectangular groove 103. A worm wheel 24 is fixedly connected to the rod wall of the rotating rod 23 near the inside of the connecting box 2, and the worm wheel 24 meshes with the worm gear 21. A transmission gear 25 is fixedly connected to the rod wall of the rotating rod 23 near the inside of the rectangular groove 103.

[0018] Furthermore, both slide rods 11 are engaged within the slide cavity 102, and the baffle plate 12 slides along the inner wall of the slide cavity 102 via the slide rods 11.

[0019] Furthermore, the first rack plate 13 and the second rack plate 14 are respectively meshed with the upper and lower ends of the transmission gear 25. The transmission gear 25 meshes with and drives the first rack plate 13 and the second rack plate 14, thereby driving the baffle plate 12 to move in different directions.

[0020] Furthermore, a handle 22 is fixedly connected to the top of the worm gear 21, and rotating the handle 22 causes the worm gear 21 to rotate.

[0021] Furthermore, the lengths of several soft baffles 15 are adapted to the length of the slide bar 11, and the soft baffles 15 can also be moved into the slide cavity 102.

[0022] Specifically, when using this utility model, if wiring is required, rotating the handle 22 forward will drive the worm 21 to rotate, and the worm 21 will mesh with and drive the worm wheel 24 to rotate. At this time, the worm wheel 24 will drive the transmission gear 25 through the rotating rod 23. The transmission gear 25 will mesh with and drive the first rack plate 13 and the second rack plate 14 respectively. At this time, the first rack plate 13 and the second rack plate 14 will slide along the sliding cavity 102 through the sliding rod 11, thereby driving the baffle plate 12 to move in different directions. At this time, wiring operations can be performed inside the wiring slot 101. After the wiring is completed, rotating the handle 22 in reverse will similarly close the two baffle plates 12 on the wiring slot 101. Then, several soft baffles 15 will abut against several wires, thereby achieving a dustproof effect.
