Abstract

本实用新型公开了一种密封圈。这种密封圈,其本体具有平滑的上、下表面,在本体的上表面设有凸台。由于在密封圈的本体的上表面设有凸台,给平面和凸台之间产生径向的阻力,从而使密封圈不再受到大面积的压力,使橡胶材料不会受到挤压而有收缩的空间,也不会出现挤死现象,提高了产品的密封性、可靠性和柔软性,又大大提高了产品的性能和使用寿命。

Description

一种密封圈
技术领域
本实用新型涉及一种密封圈。
背景技术
目前市场上出现的密封圈是根据要密封的产品工件的内外径和高度尺寸来设计,一般横截面为矩形,密封圈在装配中往往受到很大的面积压力,会使橡胶材料的密封圈变形,收缩不自如出现挤死、膨胀后将它的内部组织结构破坏,并在工件之间长期处于疲劳挤压状态,会使密封圈提早老化减少使用寿命,从而使要密封的产品容易从密封处泄露,更换又比较麻烦,给我们的生产带来了损失,并且会存在很大的安全隐患。
发明内容
为克服现有技术的缺陷,本实用新型要解决的技术问题是提供了一种不易变形、使用寿命长的密封圈。
本实用新型的技术方案是:这种密封圈,其本体具有平滑的上、下表面,在本体的上表面设有凸台。
由于在密封圈的本体的上表面设有凸台,在平面和凸台之间产生径向的阻力,从而使密封圈不再受到大面积的压力,使橡胶材料不会受到挤压而有收缩的空间,也不会出现挤死现象,提高了产品的密封性、可靠性和柔软性,又大大提高了产品的性能和使用寿命。
附图说明
图1是本实用新型的结构示意图;
图2是图1的A-A向剖视图。
具体实施方式
下面参照附图,将详细叙述本实用新型的具体实施方式。
图1是本实用新型的结构示意图。这种密封圈,其本体1具有平滑的上、下表面,在本体1的上表面设有凸台2。当然,凸台2的个数可以为一个或多个。
图2是图1的A-A向剖视图。从图2中可以看出,凸台为矩形,当然也可以为半圆形或其它形状。
优选地,在工件上的配合面使用凹槽,当把工件和密封圈组装时,将密封圈的凸台和工件凹槽配合,只需要大面积的轻压就可以,使密封效果更好。

Claims (2)

1、一种密封圈,其本体(1)具有平滑的上、下表面,其特征在于:在本体(1)的上表面设有凸台(2)。
2、按照权利要求1的密封圈,其特征在于:凸台(2)的个数为一个或多个。
