Description

Improvement type tire tube valve

Technical field

The utility model about a kind of tire valve, espespecially a kind of Improvement type tire tube valve.

Background technology

Current countries in the world are because developing the tire valve of its characteristic property separately, therefore the tire valve of prior art has Germany and Britain's formula tire valve, type such as American (containing universal vapour, locomotive) tire valve and French tire valve etc.In aforementioned in various tire valve, its gaseous core assembly of French tire valve is then arrange a locking nut on core bar body, when locking by locking nut, contiguity ring below core bar body can closely at the scalene cone place of core tube body mesopore, to prevent from getting loose, the danger having gas leakage when travelling can be avoided, reach splendid leakage-proof effect, there is the characteristic being applicable to high-pressure tyre and using, American tire valve is then because valve outer tube diameter is larger, there is the thickness of pipe of suitable size, and possess high-intensity performance etc.

Aforementioned French tire valve is because focusing on the characteristic of resistance to high tire pressure, therefore this French tire valve adopts the collocation of elongate valve body directly to lock the composite construction of the gaseous core assembly in valve body end.During only the composition of French tire valve constructs, the thickness of pipe of elongate valve body is partially thin, and have the shortcoming of undercapacity, this French tire valve is once be subject to External Force Acting, the situation of easy generation valve body fracture, and French tire tube valve is not suitable for the use of wide cut wheel rim because valve body is tiny, the valve great majority of the traditional Floor Pump in Europe are French valve, can inflate with French or English tire valve simultaneously, if but run into American cranked tire valve, must valve be changed, cause the inconvenience in use, traditional American (containing universal vapour again, locomotive) though tire valve possesses high-intensity performance because caliber is comparatively large, but gaseous core component internal is provided with spring, spring easily gets rusty and fractures, distortion, elastic fatigue, or easily because of containing foreign material (as dust, french talc when sand grains or making and installation) block the factors such as gaseous core cause losing prevent leak gas effect, and cause tire easily to lose heart and service life short and be not suitable for the shortcomings such as high-pressure tyre.

Utility model content

The utility model main purpose is to provide a kind of Improvement type tire tube valve, solve the French tire valve of existing high pressure resistant tire by this, because valve body tube wall crosses thin and undercapacity, and be not suitable for the shortcoming of wide cut wheel rim, and solve American tire valve gaseous core undercapacity, short, easy gas leakage in service life and without precisely controlling suction quantity and not being suitable for the shortcoming that high pressure resistant tire uses simultaneously.

For reaching aforementioned object, the Improvement type tire tube valve of what the utility model proposed have concurrently high pressure resistant tire pressure and high strength function comprises a valve body and a gaseous core assembly, wherein:

Described valve body has a gaseous core connection terminal portion, valve tubular body has an axis hole axially run through, the section that axis hole is positioned at gaseous core connection terminal portion comprises a screw Duan Yuyi round taper hole section, screw section is positioned at outside round taper hole section, and round taper hole section is decreasing dimensions by gaseous core connection terminal portion towards direction, the other end;

Described gaseous core assembly is French gaseous core assembly, it comprises a gaseous core pipe and a gaseous core bar, gaseous core pipe comprises a core tube body and an airtight ring, core tube body two ends are a first end and a second end, there is a center section part between first end and the second end, first end and center section part outer peripheral face form screw thread, and airtight ring, airtightly outside sheathed the second end, forms a mesopore axially run through in core tube body, described gaseous core bar comprises the core bar body that has spiro rod section and location division, one contiguity ring and a locking nut, the contiguity airtight location division being set in core bar body of ring, gaseous core bar is located in core tube body with its core bar body, locking nut is positioned at the spiro rod section being screwed onto core bar body outside core tube body, and make contiguity ring airtight joint in core tube body end, described gaseous core assembly group is located in the gaseous core connection terminal portion of valve body, gaseous core assembly is arranged in the screw section in the axis hole of valve body with the threaded center section part of its gaseous core pipe, round taper hole section sidewall in the axis hole of the airtight ring airtight abutting valve body of gaseous core pipe the second end, the gaseous core pipe first end of gaseous core assembly stretches out outside the gaseous core connection terminal portion of valve body.

The utility model constructs by the composition of aforementioned Improvement type tire tube valve, it is mainly directly arranged in the composite construction of valve body one end by locking type gaseous core assembly, the tube wall of collocation valve body is suitably increased to the size of American tire tube valve caliber, make this tire valve can maintain outside the function of the high pressure resistant tire of its French tire valve, further promote the intensity of valve body, this tire valve is made to have the function of high pressure resistant tire and high strength concurrently, wide cut wheel rim can be applicable to use simultaneously, and can use by convenient general French Floor Pump, therefore the utility model changes by the innovation of form and structure, and increase the advantage such as using function and safety of tire tube valve.
