Due to long-term use, the rubber sealing ring cannot recover to a high elastic state, which leads to the rubber sealing ring being unable to seal during use, resulting in insufficient sealing and affecting normal use.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high elastic recovery rubber sealing ring, comprising a sealing ring outer ring and a sealing ring inner ring, the sealing ring outer ring is located on the outside of the rubber sealing ring, the sealing ring inner ring is located on the inside of the rubber sealing ring, a cavity is arranged between the sealing ring outer ring and the sealing ring inner ring, a stainless steel strip is arranged inside the sealing ring inner ring, and a convex strip is connected to the inner side of the sealing ring outer ring.

[0005] In order to facilitate recovery, as a preferred embodiment of the high elastic recovery rubber sealing ring of the utility model, thirty stainless steel bars are provided, and the thirty stainless steel bars are distributed at equal intervals about the circular shape of the inner ring of the sealing ring.

[0006] In order to improve the resilience, as a preferred embodiment of the high elastic recovery rubber sealing ring of the utility model, the stainless steel strip is arranged obliquely and the stainless steel strip is plastic stainless steel.

[0007] In order to facilitate rebound, as a preferred embodiment of the high elastic recovery rubber sealing ring of the utility model, the convex strip is made of rubber material, and the cross-section of the convex strip is semicircular.

[0008] In order to ensure stable contact, a high elastic recovery rubber sealing ring is preferably used in the utility model. The outer ring of the sealing ring and the inner ring of the sealing ring are connected to form a bottom cavity on the inner side. An exhaust cavity is provided on the top of the bottom cavity. The bottom cavity and the exhaust cavity are distributed in a circular shape on the bottom surface of the cavity.

[0009] In order to facilitate stable docking, as a preferred embodiment of the utility model, a high elastic recovery rubber sealing ring is connected to the inner wall of the bottom cavity with a rubber suction cup, and the highest end of the suction cup is flush with the highest end of the exhaust cavity.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By sleeve-joining the outer ring of the sealing ring and the inner ring of the sealing ring at the joint, the rubber sealing ring is bent during the process, and the stainless steel strip and the convex strip are deformed. When the rubber sealing ring is well joined, the stainless steel strip and the convex strip are reset, so that the rubber sealing ring can be quickly rebounded and restored, thereby ensuring the safe and normal use of the rubber sealing ring;

[0012] By docking the rubber sealing ring at the docking point, the bottom cavity, the exhaust cavity and the suction cup of the inner wall of the cavity are in adsorption contact with the docking object, thereby ensuring the docking stability of the rubber sealing ring and improving the service life of the rubber sealing ring.
