The invention provides a treading type lifting air bag device, and relates to the field of lifting air bag equipment. The pedal type lifting air bag device comprises a supporting bottom plate, a pedal equipment body is fixedly arranged at the top end of the supporting bottom plate, two piston guide cylinders are arranged in the pedal equipment body, piston pressurization pedals are installed at the tops of the two piston guide cylinders, air compression channels are formed in the bottoms of the two piston guide cylinders, and the air compression channels are communicated with the piston guide cylinders. And piston gas channel inlets are formed in the bottoms of the two compressed air channels. According to the treading type lifting air bag, body weight is converted into pressure, the pressure generated by the body weight is multiple times that generated by hand strength, so that the size of a piston of a treading inflation pump can be adjusted through a large space, the inflation speed is higher than that of hand pinching inflation, and meanwhile the generated pressure is much higher than that of hand pinching inflation.
本发明提供一种脚踩式托举气囊装置,涉及托举气囊设备领域。该脚踩式托举气囊装置,包括支撑底板,所述支撑底板的顶端固定设置有脚踏设备主体,所述脚踏设备主体的内部设置有两个活塞导向缸,两个活塞导向缸的顶部均安装有活塞加压踏板,两个活塞导向缸的底部均设置有压气通道,两个所述压气通道的底部均设置有活塞气体通道入口。本发明的脚踩式托举气囊采用体重转化为压力,体重产生的压力是手劲的好多倍,所以有很大的空间可以调整脚踩充气泵的活塞大小,充气速度要比手捏充气快,同时产生的压力也比手捏充气高很多。
