[0031] 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.

[0032] Reference Figures 1-2 , Figure 4 One embodiment of this utility model provides: a rubber sleeve with a waterproof rib, including a rubber sleeve body 1, an installation groove 2 on the outer wall of the rubber sleeve body 1, the installation groove 2 for installing an outer waterproof rib 3, the inside of the installation groove 2 is filled with adhesive to fix the outer waterproof rib 3 to the rubber sleeve body 1, the inner wall of the installation groove 2 is fixedly connected to the outer waterproof rib 3, the inner wall of the outer waterproof rib 3 is fixedly connected to a telescopic rod 4, the inner wall of the outer waterproof rib 3 is fixedly connected to a spring 5, the spring 5 is sleeved on the outer wall of the telescopic rod 4, the outer wall of the rubber sleeve body 1 is provided with a threaded groove 6, the inner wall of the threaded groove 6 is threadedly connected to a threaded ring 7, the side of the threaded ring 7 near the outer waterproof rib 3 is higher than the side of the threaded ring 7 away from the outer waterproof rib 3, the inclined setting of the threaded ring 7 facilitates the insertion of the rubber sleeve body 1 into the hole.

[0033] Reference Figures 2-4The outer wall of the threaded ring 7 is provided with a guide assembly, which includes an annular groove 8. The annular groove 8 is a circular opening. Most of the annular groove 8 is located in the inner wall of the threaded ring 7. The annular groove 8 covers the guide ball 9. A small part of the guide ball 9 is outside the threaded ring 7. The guide ball 9 is rotatably connected to the inner wall of the annular groove 8. The guide ball 9 is in a protruding state on the outer wall of the threaded ring 7.

[0034] Reference Figure 5 A retaining ring 12 is fixedly connected to the inner wall of the rubber sleeve body 1. The inner surface of the retaining ring 12 is in contact with the surface of the receiving groove 13. An inner waterproof rib 10 is provided inside the rubber sleeve body 1. A guide ring 11 is fixedly connected to the end of the inner waterproof rib 10. The inner surface of the guide ring 11 is inclined. The inclined guide ring 11 reduces the wall thickness between the rubber sleeve body 1 and the guide ring 11. A receiving groove 13 is provided on the outer wall of the inner waterproof rib 10. The receiving groove 13 is used to coat the inner waterproof rib 10 with adhesive so that the inner waterproof rib 10 adheres to the inner wall of the rubber sleeve body 1. When the rubber sleeve body 1 is fitted over the outside of the cylinder, the inner waterproof rib 10 is in close contact with the surface of the object being wrapped.

[0035] Working principle: When the rubber sleeve body 1 needs to be inserted into the hole for sealing, first put the threaded ring 7 on the outside of the rubber sleeve body 1 and rotate it. The external thread inside the threaded ring 7 is gradually screwed into the threaded groove 6 and fixed on the rubber sleeve body 1. Then, align the threaded ring 7 with the inner wall of the hole to be inserted and rotate it during insertion. Due to the inclined surface of the threaded ring 7, the resistance of the rubber sleeve body 1 entering the hole is reduced. When the rubber sleeve body 1 continues to be screwed into the hole, the guide ball 9 will rotate inside the annular groove 8 to help the rubber sleeve body 1 enter the hole and provide guidance. The telescopic deformation force of the telescopic rod 4 and the spring 5 can ensure the sealing between the rubber sleeve body 1 and the inner wall of the hole under dynamic environment.
