[0012] The height of the protrusion of the sealing ring is greater than that of the sealing outer ring, and the height of the protrusion of the inner gasket is greater than that of the sealing ring.

[0013] The height of the inner pad protrusion is 2-5 mm, and the height of the sealing ring protrusion is 1-3 mm.

[0014] The inner gasket includes a first convex ring and a protrusion. The outer side of the first convex ring is correspondingly connected to the sealing ring, and the protrusion is correspondingly arranged below the first convex ring.

[0015] A plurality of reinforcement columns are evenly distributed in the reinforcement layer.

[0016] A plurality of the reinforcement columns are correspondingly inserted into the adhesive layer.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model is a stable rubber sealing ring with a sealing ring and an inner gasket, and the contact area between the main body and the outside is increased by arranging a variety of ways to improve the sealing effect.

[0019] 2. The utility model provides a stable rubber sealing ring with a reinforcement column, which can not only increase the internal structural strength of the main body, but also improve the tensile force of the base layer, so that the main body has strong stability and elasticity.
