Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, the embodiment discloses a sealing rubber ring, which comprises a rubber ring body 1, wherein an annular cavity 2 is arranged in the rubber ring body 1, an annular opening 3 communicated with the annular cavity 2 is further arranged on the inner side surface of the rubber ring body 1, annular sealing strips 4 are symmetrically arranged on two sides of the annular opening 3, one ends of the two sealing strips 4 are connected with the inner wall of the annular cavity 2 on one side of the annular opening 3, the other ends of the two sealing strips are arranged in the annular cavity 2, a plurality of arc-shaped sealing blocks 5 are arranged between the sealing strips 4 and the annular cavity 2, the sealing blocks 5 form an annular edge for sealing the opening, a guide groove 6 for controlling the displacement of the sealing block 5 is arranged at one end of the sealing block 5 facing the annular opening 3, and a driving block 7 matched with the guide groove 6 is arranged at the outer edge of one end of the sealing strip 4 facing the sealing block 5, when the sealing strip 4 is bent towards two sides, the sealing block 5 is pushed to move towards one side of the annular cavity 2 far away from the annular opening 3; a plurality of pushing blocks 8 are further arranged between the sealing blocks 5 and the annular cavity 2, the pushing blocks 8 are located at the connecting position of two adjacent sealing blocks, and springs 9 are arranged between the pushing blocks 8 and the inner wall of the annular cavity 2;
