Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a dustproof mechanism for an end, comprising a fixed dustproof cylinder 1, an inner groove 2 formed on the inner wall of the fixed dustproof cylinder 1, a cylinder 3 fixedly connected inside the fixed dustproof cylinder 1, a small gear 4 rotatably connected to the outer wall of the cylinder 3, a large gear 5 meshing with the outer wall of the small gear 4, the outer wall of the large gear 5 rotatably connected to the inner wall of the inner groove 2, a rotating cylinder 6 fixedly connected to the inner wall of the large gear 5, the outer wall of the rotating cylinder 6 rotatably connected to the inner wall of the fixed dustproof cylinder 1, a sliding groove 7 formed on the outer wall of the rotating cylinder 6, a movable dustproof cylinder 8 rotatably connected to the inner wall of the rotating cylinder 6, a limiting post 9 fixedly connected to the outer wall of the movable dustproof cylinder 8, the outer wall of the limiting post 9 slidably connected to the inner wall of the sliding groove 7, and a fixing assembly provided on the outer wall of the fixed dustproof cylinder 1 for fixing the fixed dustproof cylinder 1 to the equipment port; the fixing assembly includes a mounting ring 10, the inner wall of the mounting ring 10 fixedly connected to the outer wall of the fixed dustproof cylinder 1, and a mounting bolt 11 fixedly connected inside the mounting ring 10;

[0024] Specifically, rotating the small gear 4 can rotate the large gear 5. The inner wall of the large gear 5 is fixedly connected to the outer wall of the rotating cylinder 6. When the large gear 5 rotates, it will drive the rotating cylinder 6 to rotate on the inner wall of the fixed dustproof cylinder 1. The inner groove 2 opened on the inner wall of the fixed dustproof cylinder 1 can be used to limit the large gear 5 and also provide space for the rotation of the large gear 5. By rotating the rotating cylinder 6, the limiting post 9 is slid in the inner wall of the sliding groove 7 opened on the outer wall of the rotating cylinder 6. The limiting post 9 can rotate and change position at the same time, thereby driving the movable dustproof cylinder 8 to rotate on the inner wall of the rotating cylinder 6 and move outward to achieve the extension of length.

[0025] Reference Figure 1The outer wall of the movable dustproof cylinder 8 is fixedly connected to a first connecting block 12, the inside of the first connecting block 12 is fixedly connected to a fixed column 13, the outer wall of the fixed column 13 is rotatably connected to a second connecting block 14, and the outer wall of the second connecting block 14 is fixedly connected to a dustproof cap 15.

[0026] Specifically, the dust cap 15 is used to prevent dust from entering the equipment terminal when no wiring is being connected. A first connecting block 12 is fixedly connected to the outer wall of the movable dust cylinder 8. A fixing column 13 is fixedly connected inside the first connecting block 12. A second connecting block 14 is rotatably connected to the outer wall of the fixing column 13. The dust cap 15 is fixedly connected to the outer wall of the second connecting block 14. The dust cap 15 can be connected to the movable dust cylinder 8, and it is not easy to lose during installation or disassembly.

[0027] Reference Figure 1 and Figure 3 A rectangular block 16 is fixedly connected to one end of the dust cap 15. A rectangular groove 21 is formed on the outer wall of the rectangular block 16. A sliding groove 22 is formed inside the rectangular block 16. A sliding column 17 is slidably connected inside the rectangular block 16. A spring 20 is slidably connected to the outer wall of the sliding column 17. A limiting piece 18 is fixedly connected to the outer wall of the sliding column 17. The outer wall of the limiting piece 18 is rotatably connected to the inner wall of the sliding groove 22. A locking block 19 is fixedly connected to one end of the sliding column 17. The outer wall of the locking block 19 is slidably connected to the inner wall of the rectangular groove 21. One end of the spring 20 is fixedly connected to the outer wall of the locking block 19. The other end of the spring 20 is fixedly connected to the inside of the rectangular block 16. A locking groove 23 is formed on the outer wall of the movable dust cylinder 8. The outer wall of the locking block 19 is slidably connected to the inner wall of the locking groove 23. The outer wall of the locking block 19 is slidably connected to the outer wall of the movable dust cylinder 8.

[0028] Specifically, the locking block 19 uses a double-sloping design. When it is fully slid into the inner wall of the slot 23, the locking block 19 can be slid out of the inner wall of the slot 23 by the rectangular block 16 without using a lot of force to rotate the dust cap 15. One end of the spring 20 is fixed to the outer wall of the locking block 19 and the other end is fixed to the inner wall of the rectangular block 16. This can prevent the sliding column 17 from rotating when it slides inside the rectangular block 16. The locking block 19 is used to limit the sliding column 17 and prevent the sliding column 17 from sliding out of the rectangular block 16.

[0029] Working principle: When it is necessary to extend the movable dust cover 8 during the use of the mechanism, simply rotate the small gear 4. The rotation of the small gear 4 will drive the large gear 5, which is meshed with the small gear 4, to rotate within the inner wall of the inner groove 2 opened on the inner wall of the fixed dust cover 1. When the large gear 5 rotates, it will drive the rotating cylinder 6 to rotate within the inner wall of the fixed dust cover 1. When the rotating cylinder 6 rotates, it will cause the limiting post 9, which is fixedly connected to the outer wall of the movable dust cover 8, to slide within the inner wall of the sliding groove 7 opened on the outer wall of the rotating cylinder 6. Thus, the limiting post 9 drives the movable dust cover 8 to rotate within the inner wall of the rotating cylinder 6 and move outward, thereby extending the use of the movable dust cover 8. The telescopic extension ensures that the entire terminal is completely covered inside the movable dustproof sleeve 8, effectively preventing dust, moisture, and other contaminants from entering the terminal, protecting the electrical connection of the terminal, and extending its service life. The fixed dustproof sleeve 1 can be fixed to the terminal outlet using mounting bolts 11 and mounting rings 10. When the dustproof cap 15 needs to be installed, rotating the dustproof cap 15 causes the second connecting block 14 to rotate against the outer wall of the fixed column 13. The rotation of the dustproof cap 15 causes the rectangular block 16 to rotate. When the locking block 19 contacts the outer wall of the movable dustproof sleeve 8 during rotation, it will be forced to move and slide against the rectangular block 16. Within the inner wall of the rectangular groove 21 on the outer wall of the block 16, the locking block 19, during its movement, pushes the sliding column 17 to slide inside the rectangular block 16, causing the spring 20 to slide on the outer wall of the sliding column 17 and retract. Simultaneously, the sliding column 17, as it moves inward, pushes the limiting piece 18 to slide on the inner wall of the sliding groove 22 within the rectangular block 16. When the outer wall of the locking block 19 completely slides into the inner wall of the groove 23 on the outer wall of the movable dustproof cylinder 8, the locking block 19 will no longer be under force. At this point, the spring 20 rebounds, pushing the locking block 19 back to its original position, fully engaging with the inner wall of the groove 23, thus completing the rapid installation of the dustproof cap 15. This significantly saves on installation costs. The dust cap 15 is attached to the movable dust cover 8, making it less likely to be lost during installation or removal, thus improving the efficiency of operation and maintenance. This mechanism not only allows for the extension and retraction of the movable dust cover 8, but also ensures that the entire terminal is completely covered inside the movable dust cover 8, effectively preventing dust, moisture, and other contaminants from entering the terminal, protecting the electrical connection of the terminal, and extending its service life. In addition, it allows for the quick installation of the dust cap 15, which can significantly save installation time. The dust cap 15 is attached to the movable dust cover 8, making it less likely to be lost during installation or removal, thus improving the efficiency of operation and maintenance.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
