Description

A kind of high-ductility sealing ring

Technical field

The utility model belongs to sealing device technical field, more particularly to a kind of high-ductility sealing ring.

Background technology

Traditional sealing ring is simple circular ring structure, and docile performance is poor, then after long-time use, and rubber material holds Easily loosen, sealing effect is poor, easy tos produce the leakage of lubricating oil, finally result in inner body lubrication it is not in place, generate abrasion, make At unnecessary loss.

Utility model content

The purpose of this utility model is to provide a kind of high-ductility sealing rings, by adding high elastic rubber in sealing ring Core, and ring is fettered by rubber on pedestal and is confined, solve the phenomenon that existing seal ring seal effect price differential.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions：

The utility model is a kind of high-ductility sealing ring, including pedestal, the upper surface of the pedestal be provided with hollow posts, and The outer surface of hollow posts and inner surface form arc groove through cutting, and high resiliency rubber is both provided in the heavy wall of the hollow posts The inside of glue core, the pedestal and hollow posts is both provided with through-hole, and the lower end of the through-hole of the through-hole upper end and hollow posts of pedestal Between form corner, the surface of the pedestal forms annular groove through cutting, and tabletting and lower sheeting are provided on the pedestal.

Further, the annular surface constraint has rubber to fetter ring.

Further, the upper tabletting and lower sheeting are located at the both sides of annular groove.

Further, the equal vehicle in the upper surface of the hollow posts has fillet.

The utility model has the advantages that：

The utility model is simple in structure, easy to use, is designed for arc groove inside and outside open tubular column, increases sealing The docile area of ring, and high elastic rubber core is provided in the inner wall of hollow posts, increase the constraint ability of hollow posts in The mechanical performance of void column, and form corner between the through-hole upper end of pedestal and the lower end of the through-hole of hollow posts so that sealing Circle can inlay card on device, loosen it is de-, can be chosen whether according to demand on the outer shroud of pedestal using rubber fetter ring, to close The constraint performance of seal further strengthens.

Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
