[0031] Furthermore, a first nitrile rubber layer 5 and two second nitrile rubber layers 6 are fixedly connected inside the styrene-butadiene rubber layer 1. And the first nitrile rubber layer 5 is located between the two second nitrile rubber layers 6. The inner sides of the first nitrile rubber layer 5 and the two second nitrile rubber layers 6 are fixedly connected to the styrene-butadiene rubber layer 1. Clamping blocks 7 are fixedly sleeved on the outer sides of the first nitrile rubber layer 5 and the two second nitrile rubber layers 6. And all three clamping blocks 7 extend into the styrene-butadiene rubber layer 1. Reinforcing blocks 8 are fixedly connected to both the top and bottom of the first nitrile rubber layer 5. First limiting blocks 9 are fixedly connected to the top and bottom of the two reinforcing blocks 8. And the four first limiting blocks 9 respectively extend into the first nitrile rubber layer 5 and the two second nitrile rubber layers 6. Second limiting blocks 10 are fixedly connected inside the two second nitrile rubber layers 6. A plurality of vertical rods 11 are fixedly connected to the opposite sides of the two second limiting blocks 10. And one ends of the plurality of vertical rods 11 are respectively fixedly connected to the two gaskets 2.
[0032] Among them, the first nitrile rubber layer 5 and the two second nitrile rubber layers 6 have certain anti-pollution performance. The styrene-butadiene rubber layer 1 has good wear resistance and heat resistance. The two reinforcing blocks 8 can improve the overall strength. The four first limiting blocks 9 can improve the stability between the first nitrile rubber layer 5 and the two second nitrile rubber layers 6. The structure is simple and the overall strength is high. The three clamping blocks 7 can improve the stability between the first nitrile rubber layer 5 and the two second nitrile rubber layers 6 and the styrene-butadiene rubber layer 1. The two second limiting blocks 10 can improve the stability between the two gaskets 2 and the two second nitrile rubber layers 6.

[0034] The use process of the embodiment of the present utility model is as follows:
[0035] In use, the staff presses the insertion block 4 and moves it into the ring gasket 2, thereby driving the compression of the spring 14. Then, lubricating oil is added into the ring gasket 2. After adding the lubricating oil, the insertion block 4 is released, and the spring 14 rebounds to drive the insertion block 4 to return to its original position, preventing the lubricating oil in the ring gasket 2 from overflowing.
