AI Technical Summary

Technical Problem

Existing sealing gaskets are prone to misalignment and detachment at water pipe joints, affecting the sealing effect and making it difficult to maintain the connection.

Method used

The gasket structure is a combination of sealing ring, rubber sleeve, expansion cone sleeve and ring. The sealing ring is firmly fixed by embedding the expansion cone sleeve into the rubber sleeve through elastic deformation. The anti-slip texture of the rubber sleeve enhances the insertion strength.

Benefits of technology

It effectively prevents the sealing ring from shifting or falling off at the water pipe joint, ensuring a sealing effect and improving the installation stability and connection reliability of the sealing ring.

Abstract

本实用新型公开了一种密封橡胶垫片，包括组合式垫片；本实用新型通过设置了组合式垫片，通过将橡胶套塞入水管接头内，直至密封圈与接头贴紧，然后将膨胀锥套敲入橡胶套内侧，通过在膨胀锥套底部两侧设置了开口，开口能够为膨胀锥套提供弹性变形能力，允许膨胀锥套变形嵌入橡胶套内部，直至环部与环槽嵌合贴紧，进而完成膨胀锥套的安装，此时膨胀锥套向外挤压橡胶套，迫使其径向扩张，使橡胶套紧密嵌合在水管接头内部，从而将密封圈牢牢固定在水管接头表面，使密封圈能够保持在预定安装位置上，水管接头安装时不易发生偏移，并且不易脱落遗失。
