Abstract

本实用新型涉及一种密封圈,包括外圈和内圈,所述外圈的底端中部设有内圈,外圈的横截面呈锯齿状且锯齿的齿尖为弧形;所述内圈的横截面呈长方形;所述外圈和内圈为一体结构。本实用新型的有益效果为:由于在安装时由斜边插入,摩擦力较小,容易安装,在拉出时,由于直角和斜边共同作用,阻力更大,所以密封效果更好。

Description

密封圈
技术领域
本实用新型涉及一种密封圈。
背景技术
密封圈是机械设备中必不可少的器件,其作用在于阻止灰尘、水或者其他杂质进入内部设备中,或者是防止内部的东西泄到外边。而目前市场上常见的多是直角形式和圆形的密封圈,这样的密封圈密封效果不理想。
实用新型内容
本实用新型的目的是提供一种密封圈,以克服现有的密封圈密封效果不理想的不足。
本实用新型的目的是通过以下技术方案来实现:
一种密封圈,包括外圈和内圈,所述外圈的底端中部设有内圈,外圈的横截面呈锯齿状且锯齿的齿尖为弧形;所述内圈的横截面呈长方形;所述外圈和内圈为一体结构。
本实用新型的有益效果为:由于在安装时由斜边插入,摩擦力较小,容易安装,在拉出时,由于直角和斜边共同作用,阻力更大,所以密封效果更好。
附图说明
下面根据附图对本实用新型作进一步详细说明。
图1是本实用新型实施例所述的密封圈的剖面图。
图中:
1、外圈;2、内圈。
具体实施方式
如图1所示,本实用新型实施例所述的密封圈,包括外圈1和内圈2,所述外圈1的底端中部设有内圈2,外圈1的横截面呈锯齿状且锯齿的齿尖为弧形;所述内圈2的横截面呈长方形;所述外圈1和内圈2为一体结构。
外圈1和内圈2垂直,形成两个直角,在使用时,将密封圈通过斜面安置在连接插口中,在拉出时,由于直角和斜边共同作用,阻力更大,所以密封效果更好。
本实用新型不局限于上述最佳实施方式,任何人在本实用新型的启示下都可得出其他各种形式的产品,但不论在其形状或结构上作任何变化,凡是具有与本申请相同或相近似的技术方案,均落在本实用新型的保护范围之内。

Claims (2)
