Sealing piece

Abstract

The invention discloses a sealing piece comprising a support ring frame and an annular sealing ring, wherein an annular groove is arranged along the inner wall surface of the support ring frame, a side rib, which is connected with the annular groove in a clamping way, is arranged in the middle of the outer side surface of the annular sealing ring, the upper end and the lower end of the annular sealing ring respectively extend out of the upper end surface and the lower end surface of the support ring frame, the support ring frame is formed by connecting an upper support ring frame and a lower support ring frame by a connecting mechanism, the upper support ring frame and the lower support ring frame are respectively provided with an upper annular groove unit and a lower annular groove unit forming the annular groove, an inner groove surfaces are arranged at the inner ends of the upper annular groove unit and the lower annular groove unit, and a bulge, corresponding to the inner groove surface, is arranged at the end part of the side rib. The sealing piece has a simple structure, is convenient to process, can be prevented from being damaged by expansion due to overlarge fastening force, and has the advantage of being convenient to install and replace.

Description

technical field [0001] The present invention relates to seals. Background technique [0002] In various products such as gearboxes, pistons, and oil cylinders, the sealing performance between the shells is one of the important conditions to ensure the normal operation of the products. In the existing structure, sealing rings are usually installed between the shells and then the sealing rings are installed for sealing. , its shortcoming is that it is troublesome to turn the sealing ring into the embedded groove, and it is easy to jump out; another common structure is to directly install a flat sealing ring on the joint end face of the shell to achieve sealing, and its shortcoming is that the sealing is easy to be damaged when the connection is too tight. Swelling is also prone to offset, which affects sealing performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sealing member with simple structure and c...
