Abstract

一种车辆轮胎充气阀,将原来老桩在使用时,增 加一套充气阀体,充气阀体有充气阀芯、充气阀芯通 过手轮在机壳内顶紧装配,阀芯一端具有一阀针及阀 针挡销,阀芯另一端中心在一活动顶心,顶心15与老 桩顶心相触配合,偏心位置上设有活动阀针6,壳体4 一端配以可调螺帽2,壳体另一端侧面上有开口,端 口设有手轮固定轴。该充气阀结构简单,使用方便, 充气效率高。

Description

本实用新型涉及车用轮胎,一种轮胎充气阀。
目前各种车辆充气阀,大致主体为一个老桩,或老桩上有一螺帽,给轮胎充气时,需要用手扶着,很不方便,充气效率不高。
本实用新型的目的是提供一种轮胎充气阀,使之充气方便,小巧玲珑,效率高。
所述充气阀是将原车辆充气的老桩与一充气阀芯5通过手轮9在壳体4内顶紧装配,阀芯5一端具有阀针11及阀针挡销13,阀芯另一端中心有一活动顶心15,顶心15与老桩顶心相触配合,偏心位置上设有活动阀针6,壳体4的一端配以可调螺帽2,内有密封橡胶圈,壳体另一端侧面上有开口,端口处设有手轮固定轴孔8。
充气阀的手轮有一扁平球体9,球体一侧面设计为平面,球面偏心位置有穿轴孔8。
下面结合附图详细说明。
附图是车辆轮胎充气阀结构示意图。
如图中所示:1——老桩,2——可调螺帽,3——橡胶密封圈,4——充气阀壳体,5——充气阀芯,6——阀针,7——密封塞,8——固定销,9——偏心手轮,10——充气阀气管接头,11——充气阀芯上阀针,12——充气橡皮管,13——阀针挡销,14——老桩气门针,15——阀芯顶针。
当通过气泵将气压入气管10内时,气压把充气阀的阀针11打开,瞬间气压将阀针6压紧,使阀针6与阀芯体5呈相互启闭状态,然后搬动手轮9,手轮对阀芯体向前加压,促使阀芯体向老桩1方向紧配合,老桩的气门针14被阀芯体的中间顶心15打开,阀芯的阀针6被老桩的上边缘顶开,使气流进入老桩,同时阀芯体的压紧增加了橡胶密封圈密度,使密封圈、老桩、阀芯壳体密封紧闭配合,司机可以离开,待充气完毕。
在充气过程中,如果进气管12的气管破裂或脱掉,老桩1的气流向阀芯体的进气管接头10方向回流时,气流吹动图11的阀针与进气管相密封。因为充气阀上装有进退气阀门,故气流只能向轮胎内进气;若不向轮胎上压气,则气流自动封闭。
