[0025] Please refer to Figures 1-5 , a dust-proof sheet 2 for a linear guide slider 1 that is convenient for installation, including a slider 1 and a dust-proof sheet 2. The dust-proof sheet 2 is provided with a first groove 3 and two second grooves 6. A first through hole 4 and a second through hole 7 are respectively provided on the first groove 3 and the second groove 6. A first docking shaft 5 and a second docking shaft 8 adapted to the first through hole 4 and the second through hole 7 are respectively arranged on the slider 1. A transmission cavity 9 is provided in the first docking shaft 5. A driving gear 10 is rotatably installed in the transmission cavity 9. Two transmission sliders 15 are slidably arranged in the transmission cavity 9. Tooth grooves 19 meshing with the driving gear 10 are provided on both transmission sliders 15. Locking tongues 16 are respectively convexly provided at the ends of the two transmission sliders 15 away from each other. Through holes 21 are provided on the inner walls of both sides of the transmission cavity 9. Both locking tongues 16 extend to the outside through the through holes 21.

[0026] By providing structures such as the first docking shaft 5, the second docking shaft 8, and the locking tongue 16, when installing the dust-proof sheet 2 on the slider 1, the first through hole 4 and the second through hole 7 on the dust-proof sheet 2 can be docked with the first docking shaft 5 and the second docking shaft 8 on the slider 1, thereby realizing the docking between the dust-proof sheet 2 and the slider 1. After the docking is completed, the driving gear 10 inside the first docking shaft 5 can be rotated, so that the driving gear 10 meshes with the dimensions on the two driving sliders 15, and then the two driving sliders 15 drive the two locking tongues 16 to move away from each other. Then, the two locking tongues 16 pass through the through hole 21 and are clamped at the edge of the first through hole 4, thereby realizing the locking and fixing between the first docking shaft 5 and the dust-proof sheet 2, and then completing the connection and fixing between the slider 1 and the dust-proof sheet 2. Conversely, the removal between the dust-proof sheet 2 and the slider 1 can be realized, simplifying the disassembly and assembly process between the slider 1 and the dust-proof sheet 2 and improving the operation efficiency.

[0027] Specifically, in this embodiment, two mounting plates 13 are provided in the transmission cavity 9. Guide rods 14 are provided on the mounting plates 13. The two driving sliders 15 are respectively arranged to slide on the guide rods 14. Slide holes 22 adapted to the guide rods 14 are provided on the two driving sliders 15. The driving sliders 15 are arranged to slide on the guide rods 14 through the slide holes 22. A return spring 20 is slidably sleeved on the guide rods 14. One end of the return spring 20 is mounted on the mounting plate 13, and the other end of the return spring 20 is mounted on the driving slider 15.

[0028] Through the mutual cooperation of structures such as the mounting plate 13, the guide rod 14, and the return spring 20, the driving slider 15 can slide along the guide rod 14 through the slide hole 22, guiding the moving direction of the driving slider 15 and making the moving process of the driving slider 15 smoother. And through the setting of the return spring 20, the two driving sliders 15 can be kept away from each other under normal conditions, thereby ensuring the connection stability between the dust-proof sheet 2 and the slider 1.

[0029] Specifically, in this embodiment, a limiting hole 11 is opened at the central position of the inner wall of the transmission cavity 9. A limiting rotating shaft 12 is rotatably mounted in the limiting hole 11. The limiting rotating shaft 12 is mounted on the driving gear 10. One end of the driving gear 10 away from the limiting rotating shaft 12 is provided with a convex block 17 extending through the transmission cavity 9 to the outside. An internal hexagonal groove 18 is opened at the central position of the convex block 17.

[0030] Through the setting of the limiting hole 11 and the limiting rotating shaft 12, the rotation process of the driving gear 10 can be made more stable. And through the setting of the convex block 17 and the internal hexagonal groove 18, it is convenient to insert an external hexagonal wrench into the internal hexagonal groove 18 to make the convex block 17 drive the driving gear 10 to rotate.

[0031] Specifically, in this embodiment, the two second docking shafts 8 are symmetrically arranged on both sides of the first docking shaft 5.
