Abstract

一种防爆胎气门芯,涉及一种轮胎气门芯的改进,其特征是:芯帽与芯体之间有锁定卡环,在芯帽与芯体之间的芯杆上套有限压弹簧。在芯帽与芯体之间的芯杆上套有限压弹簧。其优点是:弥补了气门芯只能进气而不能为内胎减压的空白,消除了汽车在长时间、高速行驶时轮胎发生爆胎而造成交通事故。

Description

防爆胎气门芯
技术领域:
本实用新型属于汽车部件技术领域;涉及一种轮胎气门芯的改进。
背景技术:
目前,机动车上的气门芯只有进气和密封作用,而机动车在长途行驶或高速行驶时,经常会发生轮胎与地面摩擦过热,轮胎内气压增大导致轮胎爆裂现象地发生,严重可导致汽车交通事故的发生。
发明内容:
本实用新型所要解决的技术问题是:
提供一种在轮胎气压过高可自动放气减压的防爆胎气门芯。
本实用新型的技术方案是:
芯帽与芯体之间有锁定卡环,在芯帽与芯体之间的芯杆上套有限压弹簧。
本实用新型的有益效果是:
弥补了气门芯只能进气而不能为内胎减压的空白,消除了汽车在长时间、高速行驶时轮胎发生爆胎而造成交通事故。
图1是现有气门芯结构剖视图;
图2是本实用新型结构剖视图;
图3是本实用新型进气状态结构剖视图;
图4是本实用新型减压放气状态结构剖视图;
其中:1是芯杆、2是芯帽、3是胶圈、4是弹簧、5是胶垫、6是芯座、7是芯体、8是气门嘴、9是限压弹簧。
具体实施方式:
将气门芯芯杆加长,起连接芯帽和芯体以及加装限压弹簧的作用,芯帽与芯体之间有锁定卡环,将芯帽与芯体分离或锁定,限压弹簧套在芯杆上。
