Abstract

本实用新型涉及一种D形密封圈,该密封圈截面的外轮廓由三条直边和一圆弧线首尾相接形成一D形,且该D形的朝向与安装槽槽口的朝向是一致的。本实用新型的优点在于:可避免密封圈在安装使用过程中出现压损、啃伤及扭曲的现象,且其便于安装定位。

Description

一种D形密封圈 
【技术领域】
本实用新型涉及一种机械辅助配件,尤其涉及一种D形密封圈。 
【背景技术】
现有的密封圈大部分为纯O形的密封圈,虽然其具有结构简单、标准性程度高及通用性强的优点,但其在使用安装过程中容易露于安装槽外而出现压损的情况,且易于产生啃伤的现象,特别是与大尺寸浅安装槽配合安装时,啃伤现象尤为明显,另外,纯O形的密封圈不仅不易定位,而且使用时容易出现扭曲而导致其使用寿命不长的情况。 
【实用新型内容】
本实用新型所要解决的技术问题在于提供一种D形密封圈,可避免密封圈在安装使用过程中出现压损、啃伤及扭曲的现象,且其便于安装定位。 
本实用新型是通过以下技术方案解决上述技术问题的:一种D形密封圈,该密封圈截面的外轮廓由三条直边和一圆弧线首尾相接形成一D形,且该D形的朝向与安装槽槽口的朝向是一致的。 
本实用新型一种D形密封圈的有益效果在于:可避免密封圈在使用安装过程中露于安装槽外而导致压损的情况,且可防止啃伤现象的出现,安装时还易于定位,另外,使用时不易出现扭曲,从而能够延长其使用寿命。 
【附图说明】
下面参照附图结合实施例对本发明作进一步的描述。 
图1是一种D形密封圈的截面示意图。 
【具体实施方式】
请参阅图1,本实用新型一种D形密封圈,该密封圈截面的外轮廓由一圆弧线1和三条直边首尾相接形成一D形,且该D形的朝向与安装槽10槽口的朝向是一致的,三条直边分别为直边2、直边3和直边4。在安装使用时,直边4平面紧密放置于安装槽10内,通过直边2、直边3和直边4的共 同作用,使得密封圈能够在安装槽10内很好的定位,并且可避免密封圈露于安装槽10外而导致压损、啃伤及扭曲的情况,进而延长了密封圈的使用寿命。
