[0016] The following will further describe the present application in detail Figures 1 - 3 with reference to the accompanying drawings.

[0017] An embodiment of the present application discloses a rubber dust-proof sealing ring, which includes a rubber ring 2 and an adjusting mechanism. The adjusting mechanism includes an upper sleeve plate 1 and a lower sleeve plate 3. The upper sleeve plate 1 is connected to the lower sleeve plate 3 by setting fixing bolts 8. The rubber ring 2 is located on the outer surfaces of the upper sleeve plate 1 and the lower sleeve plate 3. The cross-section of the rubber ring 2 is a horizontally arranged V-shaped structure, and the rubber ring 2 is connected to the upper sleeve plate 1 and the lower sleeve plate 3 through an installation mechanism. A spreading mechanism is arranged between the upper sleeve plate 1 and the lower sleeve plate 3, and the spreading mechanism can make the upper sleeve plate 1 and the lower sleeve plate 3 move away from each other in their axial directions.

[0018] Further, a plurality of groups of fixing bolts 8 are provided, and the fixing bolts 8 are all inserted into the upper sleeve plate 1. Threaded holes 7 corresponding to the fixing bolts 8 are formed on the surface of the lower sleeve plate 3, and the fixing bolts 8 can be screwed into or out of the threaded holes 7.

[0019] In this embodiment, by setting up a spreading mechanism, the upper sleeve plate 1 and the lower sleeve plate 3 are moved away from each other. The upper sleeve plate 1 and the lower sleeve plate 3 pull on the rubber ring 2, so that the outer diameter of the rubber ring 2 can be reduced. Since the outer diameter of the rubber ring 2 is smaller than the inner diameter of the equipment to be sealed at this time, the rubber ring 2 can be more easily installed inside the equipment to be sealed. Then, the fixing bolts 8 are tightened, so that the upper sleeve plate 1 and the lower sleeve plate 3 move closer to each other. The upper sleeve plate 1 and the lower sleeve plate 3 no longer pull on the rubber ring 2, and the rubber ring 2 returns to its original state under its own elastic force, that is, the outer diameter of the rubber ring 2 is adapted to the inner diameter of the equipment to be sealed, ensuring the sealing ability of the rubber ring 2.

[0020] Further, the spreading mechanism includes a number of groups of T-shaped rods 10 arranged on the lower surface of the upper sleeve plate 1. The T-shaped rods 10 are arranged upside down. Column-shaped grooves 9 adapted to the T-shaped rods 10 are formed on the inner surface of the lower sleeve plate 3. The upper ends of the T-shaped rods 10 are fixedly connected to the upper sleeve plate 1. The lower ends of the T-shaped rods 10 pass through the surface of the lower sleeve plate 3 and are fitted and installed inside the column-shaped grooves 9. Springs 11 are sleeved on the surfaces of the T-shaped rods 10. The upper ends of the springs 11 are fixedly connected to the upper sleeve plate 1, and the lower ends of the springs 11 are fixedly connected to the lower sleeve plate 3.

[0021] In this embodiment, in the natural state of the spring 11, the two ends of the spring 11 respectively abut against the upper sleeve plate 1 and the lower sleeve plate 3, so that the upper sleeve plate 1 and the lower sleeve plate 3 are moved away from each other. When the fixing bolts 8 are tightened, the upper sleeve plate 1 and the lower sleeve plate 3 move closer to each other, and the T-shaped rods 10 move into the column-shaped grooves 9, and the springs 11 are compressed; when the rubber ring 2 needs to be disassembled and assembled, the fixing bolts 8 are first screwed out from the threaded holes 7, and the compressed springs 11 are restored, driving the T-shaped rods 10 and the upper sleeve plate 1 to move, so that the upper sleeve plate 1 and the lower sleeve plate 3 move away from each other, and the rubber ring 2 is thus pulled, so that the rubber ring 2 can be conveniently taken out.

[0022] Further, the installation mechanism includes inlaid strips 4 installed on the surface of the rubber ring 2. There are two groups of inlaid strips 4 and they are symmetrically arranged based on the rubber ring 2. Embedding grooves adapted to the inlaid strips 4 are formed on the outer surfaces of the upper sleeve plate 1 and the lower sleeve plate 3. The two groups of inlaid strips 4 are respectively embedded inside the embedding grooves on the outer surfaces of the upper sleeve plate 1 and the lower sleeve plate 3.

[0023] In this embodiment, the cross-sections of the inlaid strips 4 and the embedding grooves are both T-shaped structures arranged horizontally. By setting the inlaid strips 4 and the embedding grooves, the rubber ring 2, the upper sleeve plate 1 and the lower sleeve plate 3 can be stably connected.

[0024] Further, a plug plate 5 is fixedly connected to the lower surface of the upper sleeve plate 1. A slot 6 adapted to the plug plate 5 is formed on the surface of the lower sleeve plate 3. The plug plate 5 is fitted and installed inside the slot 6 and forms a moving pair inside it. By setting the plug plate 5 and the slot 6, the mutual movement of the upper sleeve plate 1 and the lower sleeve plate 3 can be guided.
