[0002] At present, the air cylinder body of many pumps on the market is only made of plastic or steel, and the outer layer of the piston is made of ordinary rubber, which makes the wear resistance of the air cylinder body and piston very poor, and it will be damaged after a long time. Cause serious wear and tear, resulting in decreased sealing performance, poor pumping effect, and even easy scrapping, resulting in waste

The invention provides an inflator. The inflator comprises a piston part, a push-pull handle, a cover plate, an inflator body, an air outlet hose and a push-pull rod. The piston part comprises a sealing ring, a piston core, a cladding layer and a piston ring. The sealing ring is made of ordinary rubber, a concave opening is formed in the piston core, the push-pull handle is fixedly connected with the top end of the push rod in a welded mode, the cover plate is installed at the upper end of the inflator body, an air inlet is formed in the cover plate, the air outlet hose is arranged at the bottom of the inflator body, and the push-pull rod is connected with the inflator body in a sliding mode. The inflator is good in abrasion resistance, long in service life, ingenious in structural design, good in inflation effect, economical and practical.
Description
technical field [0001] The invention relates to an air pump, in particular to an air pump. Background technique [0002] At present, the air cylinder body of many pumps on the market is only made of plastic or steel, and the outer layer of the piston is made of ordinary rubber, which makes the wear resistance of the air cylinder body and piston very poor, and it will be damaged after a long time. It will cause severe wear and tear, resulting in a decrease in sealing performance, poor inflating effect, and even easy scrapping, resulting in waste. Contents of the invention [0003] The purpose of the invention is to design a pump with long service life and good pumping effect. [0004] In order to realize above-mentioned function, the present invention adopts following technical scheme: [0005] An air pump includes a piston part, an air cylinder body, an air outlet hose, a cover plate, a push-pull rod, and a push-pull handle. The specific structure and connection relation...
