AI Technical Summary

Technical Problem

Existing flat washers cannot adjust the sealing height, resulting in multiple layers being stacked, which increases material costs and reduces sealing reliability. Furthermore, multiple layers are prone to assembly errors.

Method used

A multifunctional flat washer was designed, comprising a pad, a rotating component, and a positioning component. The rotating component flips the pad to increase its thickness, the positioning component fixes the position of the pad, and the protrusions prevent the bolts from loosening, thus achieving adjustable sealing height and stable fixation.

Benefits of technology

Reducing the amount of gaskets used lowers procurement and management costs, simplifies installation processes, avoids assembly errors, improves sealing reliability, extends service life, reduces the risk of bolt loosening, and ensures stable equipment operation.

Abstract

本实用新型公开了一种多功能平垫圈，涉及平垫圈技术领域，包括垫圈主体、垫块、转动组件和定位组件，垫圈主体的顶端等距开设有凹槽，凹槽内壁的底端开设有转动槽，垫块设置于转动槽的内部，转动组件与垫块连接，定位组件设置于垫块的内部，定位组件用于固定垫块的位置。本实用新型利用垫块、转动组件和定位组件相配合的设置方式，在需要使用多个垫圈时，可利用转动组件将垫块翻转至垫圈主体的上方，从而增大了单个垫圈的厚度，避免装配误差和密封不均问题，同时定位组件可对垫块的位置进行固定，可在不使用时将垫块稳定收纳在转动槽的内部，在使用时将垫块稳定固定在垫圈主体的顶端，便于使用。
