Abstract

The utility model purpose is to design a similar ball inflator to be applicable to basketball, football, volleyball and etc. The solution includes a cylinder (7), a piston(9), a piston rod(5), a safety valve (11) and a needle valve (14). On the front end of the piston rod is equipped with a piston, the piston inside a cylinder chamber (8) is fitted to the inner wall of the cylinder tightly. On the front end of the cylinder is equipped with a safety valve and a needle valve connection hole(13), the needle is equipped on the connection hole. On the tail of the piston rod is equipped with a chamber for storing the discharge needle. On the piston is equipped with a rubber piston ring to improve the hermetical. Inside the safety valve is equipped with a ball acting as a seal. Almost the present material adopts plastic and rubber, only the needle is metal, so the utility model is easy to make. Because of the advantages of lower cost, easy operation and convenient transport, the model has is widely applicable to the sports field and schools.

Description

Ball pump

Technical field

The utility model belongs to a kind of sports equipment, is used for to ball inflations such as basketball, football and vollyballs.
