Description
The utility model belongs to the bicycle technical field, relates to a kind of valve inside mouth.
At present, general adhesive tape tire tube valve is made up of valve inside and tire tube valve, uses inconvenience, if valve inside is aging or valve inside cooperates badly with tire tube valve, will miss very soon after the inflation.A kind of antifreezing valve mouth is arranged, and by spring, core print seat is formed, but core print seat often stretches, and will make spring fatigue, and sealing effectiveness will be bad like this.
The purpose of this utility model is that a kind of neostigma core mouth that prevents that spring is aging is provided on the basis of antifreezing valve mouth structure.
The utility model structure is as follows:
This tire tube valve is by core body 1; core bar 2; locating bush 3; spring 4; seal ring 5, packing seal 6, core print seat 7 is formed; core print seat 7 is an one with core bar 2; there is packing seal 6 cooperation place at core body 1 and core print seat 7, is with spring 4 on the core bar 2 in the core body 1, and is with the locating bush 3 of annular; in order to spring 4 is located; also have a garden card inside on core body 1, locating bush 3 can be blocked, the distance of locating bush 3 and garden card is less than the tired length of spring 4; so just can protect spring 4, so that core body 1 always is in good sealing state with core print seat 7.
The utility model advantage is: simple and practical, and good sealing effect.
