Abstract

本实用新型自行车自动充气泵,该气泵由气筒和 偏心轮构成,气筒内活塞推杆与偏心轮带钩连为一 体,自行车转动带动偏心轮运动。使推杆带动气筒内 活塞往复直线运动,自动为车胎充气,它具有结构简 单,造价低,使用方便等特点。

Description

本实用新型涉及一种自行车充气泵,属生活类、工具类产品,目前人们普遍使用手动打气筒给自行车打气,使用时费时费力,同时,由于其体积大笨重,携带和使用都不方便。
本实用新型的目的是提供一种能在骑行中自动为自行车胎充气并自动保压调压的气泵。
本实用新型是通过以下目来达到的,将充气泵用螺钉与夹片固定在自行车幅条上,在车行中车轮的转动带动偏心轮转动,使推杆做反复直线运动,与推杆相连的活塞在推杆的推动下前后运动。将气体通过输气管充到车胎内,达到充气的目的,车胎内气体超压时,气筒上设置的限压阀会自动排气而减压。
下面结合附图对本实用新型结构作具体说明:
附图1、2、3是本实用新型自行车自动充气泵的结构示意图:
图4是使用示意图。
其中(1)气泵体;(2)输气嘴;(3)限压阀;(4)固定螺栓;(5)推杆;(6)、(7)、(8)输气管;(9)挂勾;(10)偏心轮;(11)偏心孔;(12)自行车外胎;(13)幅条;(14)车架。
该气泵由一随园型气泵体(1)和偏心轮(10)两部分构成,气泵体(1)内腔有一活塞。活塞后端有连接有推杆(5);穿过气泵体(1)壁槽可前后移动,使活塞压缩空气。气体通过输气嘴(2)和输气管(6)、(7)、(8)将气体压入车胎。该推杆(5)与偏心轮(10)的挂勾(8)铰链在一起,构成自动充气泵整体。偏心轮(10)的偏心孔(11)安装在自行车的车轴上。车轮的转动带动偏心轮转动使推杆(5)作往复直线运动与推杆(5)相连的活塞将压缩的气体沿输气管(6)、(7)、(8)送给车胎自动充气见图1-3。
该气泵使用方法见图4。
卸下车轮,将车轴向左方调长5mm左右,并通过固定螺栓(4)将偏心轮(10)转盘凹面向右套装在车轴上,再将泵体(1)固定在(13)交叉处,调动偏心轮(10)使最大偏心远离车叉顶端,拧上输气管(6)(7)(8)拧紧车轴螺帽。
为车胎充气,支起自行车、踩动脚蹬使车轮空转或骑行,当气压达到要求时,向右侧按下推杆,即可停止充气,当车胎少时漏气时,向左侧拨起推杆,挂上偏心轮挂勾,即可在骑行中补充胎内气压。当胎内气压饱和时,输气管停止输气,气体由限压阀排出。

Claims (2)

1、一种自行车自动充气泵,其特征在于自行车轮幅条上安装有气筒,在轮轴上安装一带钩的偏心轮,通过车轮转动带动气筒上推杆与偏心轮相连,使活塞沿气筒做前后运动,为车胎充气。
2、由权利要求1所述的自行车自动充气泵,其特征在于气泵上设有限压阀。
