Abstract
The utility model belongs to the field of bicycle components, in particular to a novel cycle valve which comprises a hollow valve rod. The lower end of the valve rod is provided with an upper pressing plate and a lower pressing plate, and the upper pressing plate and the lower pressing plate are connected with a tire body. The outer surface of the valve rod is provided with threads. The valve rod is further provided with a locating nut which is used for locating the valve rod. The inner portion of the valve rod is provided with a valve core. The top portion of the valve rod is further connected with a valve locking cover. The valve core comprises an outer core body and an inner core body. A through hole which is used for gas flowing is formed in the outer core body. The lower end of the through hole is provided with a cavity body. The inner core body is arranged in a cavity of the outer core body. A blind hole which corresponds to the through hole is formed in the inner core body, and the diameter of the blind hole is larger than the diameter of the through hole. A sealing ball and a spring which plays a resetting role for the sealing ball are arranged in the blind hole. Two sides of the through hole are provided with air passageways which are communicated with the tire cavity body. The cycle valve overcomes the problem of air leakage caused by aging of the valve core and reduces maintenance of the cycle valve by people.
Description
Technical field
The utility model belongs to the bicycle part field, particularly a kind of novel valve cock.
Background technique
In the tire of existing bicycle, all valve cocks have been installed plunger, valve inside and valve gland nut, when inflating, pressurized air is by the aperture of plunger, squeeze in the tire, valve inside plays the effect of a sealing, when using bicycle, valve inside (rubber hose) is squeezed, the variation of the temperature in friction and the tire, the aging speed of valve inside causes tire to leak gas easily, affects user's use, so the utility model for the deficiencies in the prior art, improves valve cock.
Summary of the invention
The utility model has designed a kind of valve cock that does not have rubber valve inside for the defective of existing valve cock, has overcome because the aging gas leakage problem that causes of valve inside has reduced the maintenance of people to valve cock, is conducive to the long-time use of valve cock.
The utility model is achieved through the following technical solutions:
Valve cock, it comprises the valve stem of a hollow, the lower end of valve stem is provided with upper compressing tablet and the lower sheeting that is connected with tire body, the outer surface of valve stem is provided with screw thread, also be provided with the setscrew nut that valve stem is positioned on the valve stem, the inside of valve stem is provided with a valve inside, the top of valve stem also is connected with a valve tightening cover, described valve inside comprises external core and inner core-body, be provided with the through hole that a supplied gas flows on the external core, the external core of through hole lower end is provided with a cavity, inner core-body is arranged in the cavity of external core, the corresponding through hole of inner core-body is provided with diameter greater than the blind hole of through hole, is provided with ball sealer in the blind hole and ball sealer is played the spring of reset response, and the both sides of blind hole are provided with the air flow channel that is communicated with the tire cavity.
Be threaded connection between described external core and the inner core-body.
The top of described external core stretches out to be provided with and presses the hold-down ring that is attached to the valve stem top.
The end of described inner core-body is provided with is convenient to the regulating tank installing and regulate.
The utility model applies to the principle of ball valve on the valve inside, the sealing of through hole end is controlled the inflation/deflation of tire by a ball sealer, when inflation, gas has an end of through hole to enter, because the continuous increase of pressure, overcome the elastic force of spring, the promotion ball sealer moves down, and makes through hole and air flow channel conducting, and tire is inflated, after inflation is finished, pressure in the through hole has not had, and spring promotes to move on the ball sealer through hole is sealed, and the utility model does not need to adopt rubber hose, overcome the problem of the aging gas leakage that brings of rubber hose, reduced the trouble that the user uses.
