[0031] The support mechanism 3 is a ring-shaped structure with a bidirectional convex surface, which provides better support for the first sealing ring 1 and the second sealing ring 2;

[0032] The support mechanism 3 comprises a connection layer 6, a skeleton layer 7 and a filler 8. The connection layer 6 wraps the skeleton layer 7, and the filler 8 is located inside the skeleton layer 7. The outer connection layer 6 facilitates the skeleton layer 7 to better fuse with the first sealing ring 1 and the second sealing ring 2, and the inner filler 8 plays a supporting and buffering role.

[0033] The bottom of the anti-slip pad 4 is provided with a convex edge 9, and the first sealing ring 1 and the second sealing ring 2 are both provided with a clamping groove 10, and the convex edge 9 is clamped into the clamping groove 10, so that the anti-slip pad 4 is not easy to fall off from the first sealing ring 1 and the second sealing ring 2;

[0034] The surfaces of the two groups of anti-slip pads 4 protrude from the surfaces of the first sealing ring 1 and the second sealing ring 2, which helps prevent the sealing rings from sliding relative to each other when in use;

[0035] The skeleton layer 7 is a grid structure, which increases the strength of the sealing ring and prevents the sealing ring from deforming;

[0036] The filler 8 is polyethylene foam, which has certain hardness and softness.

[0038] Working principle: First, the support mechanism 3 is installed between the first sealing ring 1 and the second sealing ring 2. The outermost connecting layer 6 of the support mechanism 3 facilitates the combination of the support mechanism 3 with the first sealing ring 1 and the second sealing ring 2. The skeleton layer 7 wrapped by the connecting layer 6 in the support mechanism 3 is a grid structure, which increases the strength of the sealing ring as a whole and prevents the sealing ring from being deformed during use. The innermost filler 8 of the support mechanism 3 has a certain hardness and flexibility, and plays a supporting and buffering role. Secondly, two groups of anti-skid pads 4 are respectively installed on the surface of the first sealing ring 1 and the second sealing ring 2. By using nylon screws with multiple mounting holes 11 and multiple threaded holes 12, the two groups of anti-skid pads 4 are fixed to the surface of the first sealing ring 1 and the second sealing ring 2, and the surfaces of the two groups of anti-skid pads 4 protrude from the surfaces of the first sealing ring 1 and the second sealing ring 2 to prevent the sealing rings from sliding relative to each other during use. Furthermore, the two groups of wear-resistant layers 5 are wrapped around the sides of the first sealing ring 1 and the second sealing ring 2 to increase the wear resistance of the sealing ring during use. Finally, the rubber sealing ring has high strength and relatively wear-resistant performance.
