The invention discloses a device capable of automatically inflating tires when a bicycle travels. An inflator pump is installed on a wheel, an inflation piston is connected with an eccentric rotatingshaft, the eccentric rotating shaft and a ferrule are integrated, the ferrule is arranged on an axle in a sleeving mode, and the ferrule rotates around the axle when inflation is not conducted. A switch device, a spring piece and a wedge are installed on the ferrule, when a switch contact is pressed down, the wedge is clamped into a groove in the axle, the ferrule does not rotate around the axle,the inflation piston rotates around an eccentric shaft, inflation is started, the wheel rotates by one circle, and the piston is inflated once. When the contact is lifted, the wedge is pulled out, andinflation is stopped. A control rod is installed on the wheel, and an inclined pressing block and an inclined hook are arranged at the axis end of the control rod and used for pressing down the switch contact and hooking up the contact. The control rod is used for making contact with the contact along with the deflation and inflation of the tire through expansion and contraction to automaticallycontrol the inflation or stop of the inflation.

    一种能够在自行车行进时对轮胎进行自动充气的装置。它是在车轮上安装充气筒,充气活塞和偏心转动轴相连,偏心转动轴和套圈为一体,套圈套在车轴上,不充气时套圈绕车轴转动。套圈上安装有开关装置、弹簧片和楔子,开关触头压下时,楔子卡入到车轴上的凹槽中,套圈不绕车轴转动,充气活塞绕偏心轴转动,开始充气,车轮转动一圈,活塞充一次气。触头提起时,拔出楔子,停止充气。控制杆安装在车轮上,控制杆的轴心端有一个斜压块和一个斜钩,用来压下开关触头和勾起触头。控制杆随着轮胎的气瘪和气足伸缩,用来与触头相接触,自动控制充气或停止充气。
