Description
The utility model belongs to the bicycle technical field, relates to a kind of improvement to the valve inside mouth.
At present, general adhesive tape valve cock is made up of valve inside and valve cock, uses inconvenience, if valve inside is aging or valve inside cooperates badly with valve cock, will miss very soon after the inflation.A kind of antifreeze valve and limit-type inner spring valve cock are arranged, but structure is complicated, parts are many.
The purpose of this utility model provides a kind of plug formula valve inside mouth of simple in structure, reliable operation.
The technical solution of the utility model is as follows:
In the middle of the core body is hollow, and sealing plug and spring are arranged in hollow, and front end is with seal ring outside core body.
The utility model has the advantages that: this valve inside mouth structure is simple, parts are few, reliable operation, cost of production are low.
Fig. 1 is a plug formula valve inside mouth master sectional view.
Core body 1 is a valve inside mouth main body, and core body 1 is hollow, forms gas channel, in hollow middle portion one cone tank is arranged, sealing plug 2 withstands between cone tank and the spring 3, and spring 3 the other ends withstand on the inward flange of valve inside mouth air outlet, and front end is with seal ring 4 outside core body 1; In use, the air-flow that has air pressure backs down plug and enters tire by the air outlet, and when not needing to inflate to the inner tube of a tyre, plug tightly withstands on plug in the cone tank by tire internal air pressure pressure and spring pressure, and gas can't be overflowed.
