Abstract

活动内芯式摩托车轮胎充气阀,是一种用于摩托车轮胎进行手工充气的工具,它把现有充气阀的不动顶针改进为活动内芯顶针,解决了充气操作过程中的泄漏气现象。同时增加了内芯扳手、钥匙环新组件并组合为一体,便于携带,使用方便。

Description

活动内芯式摩托车轮胎充气阀
本实用新型是一种改进的用于摩托车充气的工具。
现有的充气阀,由于构造上的原因,在利用打气筒进行充气时,在旋装和旋掉充气阀的操作过程中泄漏气现象特别严重,造成所充气压的不理想情况,同时充气操作也有一定难度,故使许多人不能很好地使用。
本实用新型的任务是:通过对现有气阀进行改进,实现充气操作过程无泄漏气现象,保证轮胎理想充气压,同时增加钥匙环,轮胎气嘴内芯扳手两个新组件,使车手携带使用更加方便。
本实用新型的技术内容:本实用新型是把现有充气阀的固定式内芯顶针,改造为活动式内芯顶针,在旋紧和旋掉充气阀的过程中,轮胎气嘴的内芯阀不再被顶针顶开,只有在气筒夹卡紧充气阀时,活动内芯顶针才内移,顶开轮胎气嘴内芯阀进行充气,充气完毕去掉气筒夹时,充气阀顶针和气嘴内芯阀同时复位,从而避免了轮胎内充入气体的泄漏,这是现有充气阀所不具备的功能。同时本实用新型还把钥匙环、气嘴内芯扳手同充气阀组合在一起,整体功能更齐全。
本实用新型同现有充气阀相比较:功能全、使用简单、携带方便。
以下将结合图纸对本实用新型作进一步详细描述。
图1是充气阀外观图。
图2是气嘴内芯扳手和钥匙环组合外观图。
图3是日常携带时的组合外观图。
图4是图3的剖视图。
使用时旋开图(3)所示两件组合,利用图(1)所示充气阀给轮胎充气,利用图(2)所示内芯扳手拆装轮胎气嘴内芯,参照图(4)所示:⑤是具有直拉丝纹的圆型金属外壳,在旋装充阀时胶圈①起密封作用,当气筒夹卡紧外壳⑤下缘和活动内芯⑧顶口给轮胎充气时,活动内芯⑧的顶针顶开气嘴内芯阀进行充气,同时活动内芯顶针处胶圈②起密封作用,充气完毕,去掉气筒夹时弹簧⑦使活动内芯⑧复位,同时气嘴内芯阀关闭,防止了轮胎内气体外泄,然后把充气阀与内芯扳手③和钥匙环③的组合旋装在一起,可方便携带。

Claims (3)
