Description
Technical field
The utility model is related to a kind of air valve device of bicycle tube, especially it is a kind of have sealing performance reliable and
A kind of new-type air valve device used suitable for all bicycle tubes.
Background technology
The air valve device of current existing bicycle tube has English, American and three kinds of French, wherein for English gas nozzle：
It needs to use valve inside rubber tube, because rubber tube is easier aging, causes air-tightness bad, and need to be replaced frequently, together
When the inner tube of a tyre be easy for being punctured.For American type valve：Its sealing is that the little spring inside valve inside pulls sealed core close
Envelope, the quality and the quality of spring and gasket of sealing have much relations, while being influenced to be produced by factors such as road surfaces again
Raw vibrations influence whether the flexible of spring, just will produce gas leakage naturally, the inner tube of a tyre is easy for being punctured.For French gas nozzle：Its
The small ring of top is twisted tighter, and the sealing ring of the inside just draws tighter, and the leakproofness of natural gas nozzle is also better, but inflates fiber crops
It is tired, first to unscrew small ring and be pressed downward just inflating, be tightened after having beaten, and shape slight of stature, be only applicable to small rim.
Invention content
In order to overcome the shortcomings of present in existing English, American and three kinds of gas nozzles of French, the utility model provides a kind of new
Formula air valve device, the device can not only be suitable for all bicycles the inner tube of a tyre use, will not be influenced by factors such as road surfaces and
Gas leakage occurs.
Technical solution is used by the utility model solves its technical problem, it be by pedestal, nut, spring, steel ancient unit of weight, equal to 1/24 liang,
Gasket, locking nut, leak-proof sealing pad and leakproof nut composition.It is equipped with boss in the bottom end of pedestal, is equipped with spiral shell on the outside
Line fixes the inner tube of a tyre by this screw thread with nut, and the top and bottom on the inside of pedestal are respectively equipped with macropore and aperture, in holes
Between contact position formed step, and the upper end on the inside of macropore be equipped with screw thread, the inside of locking nut be equipped with through-hole, in one
The bottom end of side is equipped with indent semicircle sphere, and thick cylinder is equipped at this end of indent semi-round ball body, and thin cylinder is equipped in the other end,
It is equipped with the hexagon more than thick cylinder in the centre position of two cylinders, this hexagon can be used to tighten and can be used for being clamped
Inflator clip, and it is respectively equipped with screw thread on the outside of thick, thin cylinder, it is equipped at the step of pedestal inner top side macropore bottom
Spring is equipped with steel ancient unit of weight, equal to 1/24 liang in the other side of spring, and matched with steel ancient unit of weight, equal to 1/24 liang is that locking nut bottom end is equipped with indent semicircle sphere, locking
Set screw thread is connected with the screw thread set by pedestal inner top side on thick cylinder on the outside of nut, on the outside of locking nut
Gasket is housed on thick cylinder, so that gasket is deformed by tightening the hexagon on the outside of locking nut, to ensure two
Gas leakage does not occur for the junction of screw thread, moreover it is possible to ensure that steel ancient unit of weight, equal to 1/24 liang under the action of the spring can be set by the bottom end with locking nut side
Indent semicircle sphere is closely in contact, while the screw thread set by the thin cylinder outside of the locking nut other end is connected with leakproof nut
It connects, leak-proof sealing pad is housed in leakproof nut, by tightening leakproof nut to make up due to spring aging or road shock
Caused telescopic spring and the gas leakage generated.
Application method：Leakproof nut is unscrewed first, and the side of inflator clip is clipped in hexagon, the gas outlet of the other side
It is clipped in the outside of the thin cylinder set by the locking nut other end, the gas beaten is equipped with through-hole by the inside of locking nut,
And under the influence of air pressure, open-top steel ancient unit of weight, equal to 1/24 liang is entering the inner tube of a tyre by the endoporus of pedestal.
The utility model has the beneficial effects that due to there is the double action of gasket and leak-proof sealing pad, thrown into
The gas of the inner tube of a tyre is not will produce gas leakage, and simple in structure, and production cost is low.
