AI Technical Summary

Technical Problem

In the prior art, in the airtightness test, the sealing effect of threaded holes with curved end surfaces is poor, and problems such as lax sealing, leakage, long drying time and residual glue are prone to occur, which affects the test results and product quality.

Method used

A sealing gasket is designed, including a gasket main body, a first O-shaped sealing ring and a second O-shaped sealing ring. The first end face of the gasket main body is similar to the shape of the sealing rod member, and the second end face is similar to the curved surface of the object to be sealed. The sealing fit is formed in different directions through the O-shaped sealing ring to improve the sealing effect.

Benefits of technology

The sealing gasket is simple in structure and easy to use. It can effectively improve the sealing effect of the hole to be sealed, reduce leakage risk, shorten the airtight test time, and reduce glue residue, improve product quality and testing efficiency.

Abstract

The invention relates to the technical field of sealing gaskets, and discloses a sealing gasket, a sealing assembly part and a device used for an airtight test, the sealing gasket is used for being clamped between a plugging rod piece and a to-be-sealed object when the plugging rod piece plugs a to-be-sealed hole of the to-be-sealed object, and the sealing gasket comprises a gasket body which comprises a first end face, a second end face and a first through hole, the first end face comprises a plane structure similar to the shape of an abutting face of the plugging rod piece, the second end face comprises an inclined curved surface structure similar to the shape of an inclined curved surface of an object to be sealed, the second end face is back to the first end face in the first direction, and the first through hole penetrates through the first end face and the second end face in the first direction; the first O-shaped sealing ring is arranged on the second end face; the second O-shaped sealing ring is arranged on the first end face. The sealing gasket is simple in structure and convenient to use, the sealing effect of the to-be-sealed hole can be improved, and the subsequent air tightness test can be improved.
