An angle pipe is arranged on the upper part of the vertical frame, and the rod sleeve is fixed with a handle after passing through a hole on the upper part of the angle pipe. One end of an inflator rubber pipe is fixed on an air outlet pipe on the bottom of the vertical frame. The clamp of the core of the inflator rubber pipe is fixed on the beam ear of the vertical frame through screw nails and screw nuts. A lock is opened by a key in inflating, a lock beam is taken out, a saddle is forward shifted, and the inflator is exposed to inflate. The utility model has the advantages of simple structure, easy fabrication, and convenient use.

Description

Be located at the pump-up device on the upright beam of bicycle

The utility model relates to a kind of pump-up device of being located on the upright beam of bicycle.Also be applicable to manual tricycle.

Existing bicycle does not generally have pump-up device, the damage of tire unsaturated vapor or valve inside can't be inflated after replacing with the neostigma core in the way by bike, real is cyclist's a great problem, for this reason, the producer that has has designed portable inflator, but because of its capacity is too little, the effort of inflating is time-consuming and lose easily; Though used inflator kind is a lot, all inconvenience is carried.

The purpose of this utility model is to overcome above-mentioned weak point, a kind of piston and piston rod is contained in Li Liangli and design, piston rod be fixed on bar cover bonded assembly on the vehicle seat and be located at pump-up device on the upright beam of bicycle; With the vehicle seat reach, can inflate, in the time of by bike, get final product moving behind the vehicle seat, very convenient, can not lose yet

The utility model content, Li Liangli is equipped with the piston rod of band piston, and piston rod is contained in the bar cover, can adjust its axial location and fastening by screw between the two, and Li Liang is equipped with cornue in top, and the bar cover passes the Kong Houyu handle on cornue top and fixes; The freeing pipe of one end of inflator sebific duct and upright beam bottom is fixed, and the valve inside clip of inflator sebific duct can be fixed on the Liang Ershang of upright beam by screw-nut.

The utility model advantage, the piston rod of band piston is loaded in the upright beam of bicycle, and the upright double air cylinder body of doing of beam during use, only needs the vehicle seat reach can be inflated; In the time of by bike, will move behind the vehicle seat, air cylinder piston rod and handle all are under the vehicle seat, can not lose
