Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber sealing pieces, in particular to a high-efficiency wear-resistant rubber sealing piece structure. Background Art
[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from invading components inside machinery and equipment.
[0003] The prior art patent document with publication number CN213744884U provides: a wear-resistant rubber seal, comprising an annular body, sealing rings are arranged on the end faces of the two ends of the body along the axial direction, the sealing rings are arranged along the inner edge and the outer edge of the body respectively, and wear-resistant patterns are arranged between the sealing rings, and a support structure is arranged on the radial outer wall of the body. The utility model has stronger wear resistance and can extend its service life.
[0004] However, during the use of the existing high-efficiency wear-resistant rubber seal structure, the seal will generate friction during long-term use. Although the seal can play a wear-resistant role, the rubber seal will be worn out under long-term friction. After the friction occurs, the seal cannot shrink the ring opening, resulting in the rubber seal being unable to form a seal after wear. For this reason, we propose a high-efficiency wear-resistant rubber seal structure. Utility Model Content
