Abstract
The utility model relates to an inflating valve for inflating bicycle tubes. The technical scheme is: the utility model comprises a hollow main body, wherein, the outer end of the main body is fitted to an inflator, and a gas outlet is arranged radially on the inner end of the main body; wherein, an air return pore open to the cavity is arranged on the inner end of the main body, a guide shaft is arranged axially in the cavity outward along the air return port, and the guide shaft is fitted to a boss part in middle of the main body in a sealed manner. A seal ring is fitted over the boss part in middle of the main body, a seal ring is fitted over the guide shaft, and a bulge ring is arranged on the main body. Since the utility model employs a novel structure, the valve inside that tends to age can be omitted, and the tire can be kept free of leakage for long time, and the service life of the tire can be improved.
Description
One, technical field: the utility model relates to a kind of valve cock of bicycle inner tube qi of chong channel ascending adversely.
Two, background technique: the main body of existing bicycle valve cock is perforation in the middle of, bottom sealing, and the rubber valve core outside inner end radially is provided with the air outlet and is enclosed within the air outlet cooperates, and comes to inner tube of a tyre injecting gas.Because valve inside is easily aging,, change valve inside so the generation of inner tube of a tyre gas leak phenomenon often occurs.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of bicycle valve cock is provided.
Its technological scheme is: the main body that connects in the middle of comprising, the outer end of main body cooperates with pump, the inner radially is provided with the air outlet, it is characterized in that: the inner end in main body is provided with the return-air hole that runs through with inner chamber, along axial device in the outside cavity of return-air hole the axis of guide is arranged, the internal projection at the axis of guide and main body middle part partly is sealed and matched.The outside of the internal projection in the middle part of main body is with seal ring, is with seal ring on the axis of guide, is provided with bulge loop in the outside of main body.
Effect of the present utility model is: the valve cock outside is by the sealing of the valve hub interference on seal ring and the tire, and is inner by the axis of guide and seal ring and body seal.When inflating in tire, gas pressure is pushed the axis of guide to bottom, and gas enters tire from the air outlet that radially is provided with; Behind the tire top off, return-air hole oppositely promotes the axis of guide and moves, and realizes and the sealing of main body, seals the air outlet simultaneously.Because the utility model has adopted new structure, omitted aging easily valve inside, solved the worry of frequent replacing valve inside, make tire keep air tight for a long time, the working life of improving tire.
Four, description of drawings:
Accompanying drawing is an a kind of embodiment's of the present utility model structure sectional view.
Five, embodiment:
With reference to accompanying drawing, main body 1 is a cylindrical body that the centre is run through, be provided with the bulge loop 2 that cooperates with valve hub outside thread cap in its outer end, the middle part of main body 1 is provided with internal projection, the outside is with seal ring 3, the inner end of main body 1 radially is provided with air outlet 4 and inserts in the valve hub, and the centre is provided with the axis of guide 7 and seal ring 5, and the axis of guide 7 and seal ring 5 can be free to slide between inner return-air hole 6 and internal projection.Main body can be global design, also can be that split connects to form.
Claims (2)
1, a kind of bicycle valve cock, the main body that connects in the middle of comprising one, the outer end of main body cooperates with pump, the inner radially is provided with the air outlet, it is characterized in that: the inner end in main body is provided with the return-air hole that runs through with inner chamber, along axial device in the outside cavity of return-air hole the axis of guide is arranged, the internal projection at the axis of guide and main body middle part partly is sealed and matched.
2, bicycle valve cock according to claim 1 is characterized in that: the outside of the internal projection in the middle part of main body is with seal ring, is with seal ring on the axis of guide, is provided with bulge loop in the outside of main body.
