Abstract
The utility model relates to an inner tube valve inside for power vehicles, which is composed of a core body, a sealing ring, and a plastic soft piston. The core body, the sealing ring, and the plastic soft piston are assembled together. The utility model has the advantages of simple structure, long service life, and inflation labor saving, which avoids the defects that a latex tube used for the traditional inner tube valve inside is frequently damaged and needs frequent replacement, and labor is consumed when the traditional inner tube valve inside is inflated.
Description
The utility model relates to a kind of cycle tube valve inside.
At present, traditional cycle tube valve inside is that an end that utilizes emulsion tube to be enclosed within the metal air tube reaches seal action with made such as copper, aluminum alloys, but the employing emulsion tube is aging easily being clamminess in summer, yielding again in the winter time, cause gas leakage, need often to change emulsion tube, cumbersome.This traditional valve core structure is simultaneously inflated special effort.
The purpose of this utility model provide a kind of simple in structure, inflate the cycle tube valve inside of laborsaving and long service life.
The technical solution of the utility model is achieved in that this valve inside is to be assembled by core body, seal ring and soft piston, its core body partly is a monolithic construction, there is through hole the centre, one boss and a groove are arranged in the intermediate portion of core body, be provided with seal ring in groove, have two pores in the place ahead of core body, the front end of core body is designed to profile of tooth, promptly protect tooth, soft piston is positioned in the through hole in core body the place ahead.After soft piston is put into through hole, will protect tooth and close up a little, avoid soft piston to deviate from.
The soft piston of this inner tube valve core is made with plastics or rubber.
When the utility model uses, this valve inside is installed on the valve cock, compress by seal ring with big hoop and to make the sealing of core body and valve cock, during qi of chong channel ascending adversely, the through hole of gas by the core body center is pushed into the front end of core body with soft piston, and two pores of gas on core body enter the inner tube of a tyre, after stopping to inflate, because the pressure of inner tube of a tyre gas, soft piston is pushed into the pore place of core body, make its sealing.
Advantage of the present utility model: this inner tube valve cored structure is simple, inflate laborsaving, long service life.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structure cut-away view of the present utility model.Wherein (1) is core body; (2) be seal ring; (3) be the soft pistons of plastics; (4) be boss; (5) be pore; (6) be to protect tooth.
With reference to diagram, valve inside of the present utility model is to be assembled by core body (1), seal ring (2) and the soft piston of plastics (3).Its core body (1) is designed to monolithic construction, there is through hole the centre, in the intermediate portion of core body (1) boss (4) and a groove are arranged, be provided with seal ring (2) in the groove, have two pores (5) in the place ahead of core body (1), the front end of core body (1) is designed to profile of tooth, promptly protect tooth (6), the soft piston of plastics (3) is positioned in the through hole in core body (1) the place ahead, after the soft piston of plastics (3) is packed the through hole of core body (1) into, to protect tooth (6) and close up a little, and avoid the soft piston of plastics (3) to deviate from.
Claims (2)
1, a kind of cycle tube valve inside, comprise core body and seal ring, it is characterized in that this valve inside is to be assembled by core body, seal ring and soft piston, its core body partly is a monolithic construction, and there is through hole the centre, one boss and a groove are arranged in the intermediate portion of core body, be provided with seal ring in groove, have two pores in the place ahead of core body, the front end of core body is designed to profile of tooth, promptly protect tooth, soft piston is positioned in the through hole in core body the place ahead.
2, inner tube valve core according to claim 1 is characterized in that soft piston makes with plastics or rubber.
