Abstract
The utility model relates to a pedal air pump, comprising an air cylinder, a piston, an air-out pipe and an air nozzle. The utility model is provided with a support frame which is hinged by two rigid frames. The air-out end of the air cylinder and the outer end of the piston rod are respectively hinged on the two frames. The piston rod is sheathed with a pressure spring which is pressed between the air cylinder and the piston rod. The end of the upper frame is provided with a pedal. The utility model presses the air through pedaling by manpower. The reset of the pressure spring has labor saving and high efficiency. The utility model can provide the high pressure air. The utility model has the advantages of small volume, convenient portability and convenient storage.
Description
The utility model working tool relates to a kind of manpower air pump, particularly a kind of foot-operated air pump.
Common in the market manpower air pump mainly contains manual inflator and foot-operated " bellows " two kinds.The former piston stroke is long, needs two grips when inflating, whole body firmly, effort during use, efficient are low.Though the latter is laborsaving, it clamps air chamber and has limited air pressure, can not inflate to zone of high pressure such as automobile tires.
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of laborsaving, efficient is high, can give the foot-operated air pump of zone of high pressure air feed, volume is little, and is easy to carry.
The utility model is achieved through the following technical solutions: a kind of foot-operated air pump comprises cylinder, piston, steam outlet pipe and valve.It has one by 2 rigid frames support that to be upper frame link with underframe, and 2 rigid frame Plane intersects are rotatable each other.Cylinder and piston rod place in 2 rigid frame intersecting plane angles, and the cylinder outlet side is articulated on the upper frame, and the piston rod outer end is hinged on the underframe.Upper cover of piston rod is equipped with stage clip and withstands between cylinder and the piston rod fixed end.Pedal is equipped with in the upper frame end.
The utility model with foot-operated action, utilizes spring reset fully, and is laborsaving, efficient is high, can get to 7 more than the barometric pressure.The time spent can not turn up, and volume is little, and is easy to carry.
The utility model is described in further detail below in conjunction with accompanying drawing:
