The invention discloses a rubber washer which comprises a washer body which is of a step shape; and the rubber body is provided with a mounting hole. The rubber washer is characterized in that the connecting surface of the step shape is a slope surface which forms an included angle of 30-60 degrees with the axis of the washer. Compared with the prior art, the connecting surface of the rubber washer provided by the invention is a slope surface, and forms an acute angle with the axis, a closed angle is formed at the top, and when in mounting, the closed angle is streesed and is easy to deform, thus the seal property is improved.
Description
Technical field [0001] The invention relates to a gasket, in particular to a rubber gasket for sealing and improving connection reliability. Background technique [0002] The existing rubber gasket is stepped, and the center is a through hole, and the connecting surface of the step is perpendicular to the axis of the gasket. When the rubber gasket is installed and used, the entire connecting surface is in contact with the installed parts, and the force-bearing surface is large and not easily deformed during locking, so the sealing performance is not good. Summary of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art, and to provide a rubber gasket with a large deformation of the connecting surface to improve the sealing performance and connection reliability. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a rubber gasket, incl...
