Abstract

本实用新型提供了一种改进的充气轮胎气门芯,它采用一个堵圈,一个堵气阀代替传统的乳胶管封闭气体的结构。达到充气轻松,使用寿命长的目的。

Description

本实用新型涉及一种改进的充气轮胎气门芯,特别是一种打气省力又能防漏的气门芯。适合于各种非机动车充气轮胎用。
现有非机动车轮胎气门芯主要是由气门芯和细乳胶管配合,将气门芯插入气门内,并用螺帽压紧。细乳胶管既是进气阀又是防泄漏阀。但是采用乳胶管作进、闭气阀时,易产生因乳胶管老化破裂,导致轮胎漏气现象,给使用者带来诸多麻烦。同时因乳胶管紧紧套在气门芯外,而使打气者需耗费很大精力。如采用高压泵充气,则要增加设备投资。
本实用新型的任务是要提供一种改进的气门芯,它能有效地防止泄漏气,又能很省力地进行充气,并且使用寿命大大超过用乳胶管的气门芯。
本实用新型的任务是以如下方式完成的:在传统气门芯的中段开一环形槽,槽外嵌一只与环形槽紧配的橡胶堵圈,以阻止气体漏出。气门芯内部呈管状,在管状气门芯内有一个可上下移动的堵气阀,当充气时,堵气阀受到气筒内气体的压力向气门芯的一端移动,打开进气口,压缩气体从泄气孔流入轮胎。当气筒内压力低于轮胎内压力时,轮胎内的压缩气体将堵气阀顶向气门芯的另一端,关闭气门芯的进气口,轮胎内的气体便不会泄漏出来。轮胎内的压力越大,堵气阀与进气口的接触就越紧密,气密性也越好。当采用下述实施例结构时,仅需在传统的气门芯上略作修改便可。
以下将结合附图对本实用新型作进一步描述。
图1是本实用新型的外形图。
图2是本实用新型的剖视图。
参照图1、2,一个由铜质材料制成的气门芯〔1〕,在气门芯的中段开一环形槽〔5〕,在环形槽外套入一个耐酸橡胶制成的堵圈〔2〕,作气门与气门芯结合部堵漏用。在管状的气门芯中有一个用耐高温塑料制成的堵气阀〔3〕,当外压力大于轮胎内压力时,堵气阀便打开,压缩气体可通过泄气孔〔4〕流入轮胎内,当轮胎内压力大于外压力时,堵气阀关闭,如此周而复始便可很轻松地向轮胎充气。

Claims (3)

1、一个由铜质材料制成的气门芯[1],其特征是气门芯中段有一堵圈[2]和一个堵气阀[3]。
2、根据权利要求1所述的气门芯,其特征是堵圈〔2〕采用耐酸橡胶。
3、根据权利要求1所述的气门芯,其特征是堵气阀〔3〕采用耐高温塑料。
