Abstract
The utility model discloses a tire charger valve that is characterized in that: a valve body is internally provided with a cavity; the cavity is internally provided with a spring; the valve body is provided with a handle with a through hole; and the lower end of the valve body is provided with a pressing cap. The utility model adopts a sing hole and is characterized in a small size and wide application and has the advantages of wide application for bicycles, autobikes and automobiles, convenient utilization and long service life.
Description
Technical field:
The utility model relates to the inflatable tool of tire, specifically a kind of universal tyre tube valve that is mainly used in bicycle, motorcycle and automobile.
Prior art:
Existing tyre tube valve mostly comprises valve body, is contained in valve seat and spool in the valve body, and this gas charging valve is two, one can be used for the bicycle inflation, the other end can be the motorcycle inflation, because the aperture difference of Bicycles and Motorcycles is used trouble, and in case get the position, hole wrong, this inflatable tool is easily impaired, and the sealing of other two different apertures spools and valve seat mostly is plane, and this gas charging valve is the stack of two kinds of gas charging valves, big, the easily gas leakage of volume, working life is also shorter.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved tyre tube valve, and it can overcome some shortcomings of the prior art.
The technical solution of the utility model is achieved in that tyre tube valve, it mainly comprises valve body, be contained in valve seat and spool in the valve body, it is characterized in that: in valve body, be provided with cavity, spring is housed in cavity, on valve body, be provided with the handle that has through hole, establish a pressure cap in lower end near valve body.
The utility model adopts single hole, has the wide characteristics of the little versatility of volume, can be widely used in bicycle, motorcycle, automobile, and is not only easy to use, and long service life.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises valve body 1, be contained in valve seat 3 and spool 2 in the valve body 1, it is different from prior art and is: be provided with cavity in valve body 1, spring 5 is housed in cavity, on valve body 1, be provided with the handle 7 that has through hole 6, establish a pressure cap 4 in lower end near valve body 1, an end of valve seat 1 is a macropore in force, the other end of valve seat has a circular hole, the approximate conical surface shape that is of the macropore of valve seat 1, one end of pressure cap is established a macropore 8, and the other end of pressure cap is established an aperture 9, and an end of present embodiment spool 2 has a boss 10, put a spring 5 in boss 10 disposal, the lower end of spool boss is approximate to be hemispherical, is a cylindrical body in hemispheric lower end, opens a notch 11 in cylindrical end.The utility model is because the bootable two kinds of different classes of tyre inflation of big aperture of pressure cap, the approximate conical surface shape that is of the macropore of valve seat, the sealing shape that becomes approximate spherical in shape of itself and spool boss lower end, at ordinary times under the double action of spring and gas pressure, can not leak gas, the handle that has through hole during inflation can be used as the connecting head that connects the inflation source sebific duct, the through hole of handle inside is as compressed-air actuated through hole, this moment tyre valve by pressure cap macropore and aperture and back down spool, spool pressure spring and the approximate approximate conical surface shape place that is of the macropore of lifting off a seat at hemispherical place that is that makes spool boss lower end, the gap appears in the joint of valve seat and spool, the joint that is valve seat and spool breaks away from the sealing shape, pressurized air enters the cavity of valve body along the gap of valve seat and valve core chamber, enter tire through the through hole in the handle again, finishes inflation.
Claims (4)
