Problems solved by technology

Although the structure is simple, the leather cup is prone to upward air leakage during compression, which reduces the air pressure, and it often takes time and effort to inflate the air.
In addition, the structure of the traditional pump restricts its material except for the cup and the handle to only use the outer cylinder, base and cup rod made of metal, which wastes metal materials, and is easy to absorb moisture and rust, and the service life is short

Abstract

The present invention relates to a high-pressure quick bicycle pump. It includes pump body, piston and press-handle, said pump body has external tube and internal tube, the upper end of the external tube is connected with press-handle, and its lower end is equipped with a seal cover, said internal tube is placed in the internral cavity of the external tube, its upper end is connected with a piston seat, the periphery of said piston seat is equipped with two elastic sealing rings. The centre of said piston seat has a hollow cavity in which the piston in mounted, and said piston is formed from upper guide column, middle cone surface and lower cylinder which are connected into one body. Said invention can be made by using plastic components and its working efficiency is high.

Description

technical field [0001] The invention relates to an air cylinder for inflating vehicle tires. Background technique [0002] The air pump is used to inflate the tires of the vehicle, and it is a tool that both non-motor vehicles and motor vehicles must be equipped with. Traditional inflators use a leather cup as a piston, and the mouth of the cup is downwards. Using the elastic change of the cup, the cup goes up to inflate, and the cup goes down to compress the air. Although the structure is simple, the leather cup tends to leak upwards when the air is compressed, which reduces the air pressure, and it often takes time and effort to inflate the air. In addition, the structure of the traditional pump restricts its material except for the cup and the handle to only use the outer cylinder, base and cup rod made of metal, which wastes metal materials, is easy to absorb moisture and rust, and has a short service life. Contents of the invention [0003] The purpose of the presen...
