Abstract
The utility model belongs to the technical field of tires for verticals, in particular to a valve cock which is used on a pneumatic-tire or a tubeless rim. The utility model is characterized in that a one-way valve is arranged in a cavity body of a chassis, wherein the abutted surface of the chassis and the inner end of the one-way valve is a pyramidal face. The utility model has the advantages of avoiding traffic accidents which are caused by suddenly losing pressure because the outer end of the valve cock is broken off, and the utility model has excellent sealing property.
Description
Technical field:
The utility model belongs to the tire for vehicles technical field, is specifically related to a kind of inflation with the valve cock that uses on tire or the tubeless wheel rim.
Background technique:
The valve cock of inflation usefulness on the existing tire or on the tubeless wheel rim, be valve inside and sealing protection cap by Valve tip body one end, the base of the other end constitutes, during use, be installed on tire or the tubeless wheel rim by base, seal by valve inside and sealing protection cap, its shortcoming is because valve inside and sealing protection cap are positioned on the outer end of Valve tip body, the Valve tip body major part is exposed to outside tire or the wheel rim, in the vehicle driving process, very easily be subjected to the collision of external force and fracture, make tire decompression at once, cause traffic accident, even cause car crash.
Summary of the invention:
The purpose of this utility model provides a kind of under situation about not influencing the normal inflation of tire, can avoid because of the Valve tip body outer end fractures the traffic accident that causes the tire rapid decompression to cause, and the valve cock of good airproof performance.
The technical solution of the utility model is: a kind of valve cock, establish valve inside and sealing protection cap at Valve tip body one end, and the other end is established base, it is characterized in that being provided with one-way valve in the cavity of base.Wherein, the inner abutted surface of described base and one-way valve is the conical surface.
Owing to adopt technique scheme, on the base of valve cock, be provided with one-way valve, improved sealability to tire, have and can avoid because of the Valve tip body outer end fractures the traffic accident that causes the tire rapid decompression to cause, and the advantage of good airproof performance.
Description of drawings:
Come the technical solution of the utility model is elaborated below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
Embodiment:
With reference to the accompanying drawings, a kind of valve cock is established valve inside 2 and sealing protection cap 3 at Valve tip body 1 one ends, and the other end is established base 4, is provided with one-way valve 5 in the cavity of base 4, fixes with bung flange.Base 4 is the conical surface with one-way valve 5 inner abutted surfaces.During use, base is fixed on tire and the steel ring, or changes the structure of wheel rim, directly be fixed on the wheel rim and get final product with hexagon nut, packing ring.
