Abstract

本实用新型提供了一种向中心凹陷一定角度的密封圈,密封圈周边向中心凹陷呈150-170度夹角,可更好实现密封作用。

Description

一种密封圈
技术领域
本发明涉及工程器具领域,具体地说是一种向中心凹陷一定角度的密封圈。
背景技术
当前广泛使用的密封圈多为圆形平面结构,仅靠压力来实现密封的作用。
发明内容
为解决上述问题,本发明提供了一种向中心凹陷一定角度的密封圈。
本发明是这样实现的:密封圈周边向中心凹陷呈150-170度夹角,利用受压时产生的预紧力提供良好的密封作用。
发明的有益效果是:利用夹角产生的被动应力,改变以往的面密封为线密封,可更好实现密封作用。
附图说明
下面结合附图作进一步说明。
附图是本发明的纵面结构示意图。
图中:1、夹角。
具体实施方式
密封圈周边向中心凹陷呈150-170度夹角1,周边凸起、中心凹陷的结构可更好地实现密封作用。
