[0025] When the rubber sealing ring body 1 is sealing, the metal support body 1 3 and the metal support body 2 4 are compressed and close to each other, and at this time, the central rubber column 5 and the rebound spring 6 are compressed synchronously. When the rubber sealing ring body 1 is not sealing, the central rubber column 5 and the rebound spring 6 can drive the rubber sealing ring body 1 to rebound quickly, which will not affect the sealing effect next time;

[0026] Depend on Figures 1 to 6It is shown that the central rubber column 5 is inserted and connected to the metal support body 1 3 and the metal support body 2 4 and is an integrated structure with the rubber sealing ring body 1.

The metal support body 1 3 and the metal support body 2 4 are both composed of an annular support end plate 10, an annular limiting outer ring 11 and an annular limiting inner ring 12. The annular limiting outer ring 11 and the annular limiting inner ring 12 are respectively fixedly connected to the two sides of the annular support end plate 10 close to one end of the central rubber column 5.
