Abstract
A pedal air pump comprises a cylinder, a piston, an air outlet pipe and an air faucet. The air cylinder is hinged with 2 rigid frames, the air outlet end of the air cylinder and the outer end of the piston rod are hinged with the 2 rigid frames respectively, a pressure spring is sleeved on the piston rod and propped between the fixed end of the air cylinder and the fixed end of the piston rod, and a pedal is arranged at the end part of the upper frame. The pressure spring is reset by pressing the pressure spring by manpower, thereby saving labor, having high efficiency and being capable of supplying high-pressure air. Small volume, convenient carrying and 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:
