Abstract

The utility model relates to the structure of an inflating nozzle used on a tyre. The utility model is characterized in that a valve inside is no longer arranged in an inflating nozzle pipe of the tyre, but a circumscribed inflating connecting nozzle is arranged on the front end of an inflating nozzle pipe of the existing tyre, or the circumscribed inflating connecting nozzle is arranged on a base of the inside inflating nozzle pipe after an outside inflating nozzle pipe is removed, wherein, the circumscribed inflating connecting nozzle is composed of an intake charge nozzle pipe, a big intake charge cavity pipe, a valve plug, a movable central column, a reset spring of the valve plug together, etc. The structure of the existing inflating nozzle is replaced by the structure of the circumscribed inflating connecting nozzle. Because an intake charge cavity of the novel air inflating nozzle is big, the type can be quickly inflated under the condition that the tyre which is provided with the air inflating nozzle needs not add or reduce any accessories.

Description

A kind of New-type tyre is inflated and is chewed

The utility model relates to inflating of using on a kind of tire and chews structure.

The inflation of tire that is just using is at present chewed, general most is to be used in the method for chewing pipe installed inside valve inside of inflating, inflate and stop carcass internal memory gas to leak outside, it is thin but the valve core body is long, and the inside also has complicated structure, utilize the very little space air inlet of central authorities only, thereby make to inflate and chew the interior tire of valve inside that uses when inflating, existence is crossed gas drawback very slowly in from air pump toward tire, so promptly can prolong the time of inflating greatly, when in big vehicle tyre, inflating, also often have to twist and remove valve inside, beaten gas and reinstalled valve inside.Promptly trouble is bothersome, produces environmental pollution again, so chew structure for inflating of valve inside of dress on the tire, just has and carries out improved necessity.

The purpose of this utility model, exactly will propose a kind of easy to usely and or else chew any device on the pipe with removing to inflate when inflating, structure is chewed in newly inflating of just can be fast supplying gas in the tire.

In order to achieve the above object, the utility model chews to existing inflation of tire that to improve be to remove inflation of tire to chew the valve inside that all must install now in the pipe, change into inflating and chew pipe front end etc., installs one and have the external air valve that reaches bigger inner air-inlet cavity than major diameter and connect and chew.

Inflation of tire is chewed after improving according to preceding method, just can reach easy to use naturally and the characteristics of air inlet fast.

Below just in conjunction with the accompanying drawings features more of the present utility model are once described:

In the accompanying drawing of the present utility model, Fig. 1, Fig. 2 are that inflating of two kinds of different profiles chewed structure, and Fig. 3 is that valve plug bottom is loaded onto down inflating of general thick Returnning spring and connect and chew structure, and Fig. 4 then is that valve plug bottom is adorned inflating of up-small and down-big Returnning spring and connect and chew.

In the utility model accompanying drawing, 1 inflate chew pipe 2 big air inlet lumen 3 valve plugs 4 slidably the bar bolt 7 gas-entered passageways 8 connection seal rubber pads 9 of center pillar 5 valve plug Returnning springs 6 band center pillar movable spans normally inflate and chew tube head 10 valve sealing rubber cushions

Valve plug in the utility model can be the structure of full spherical as Fig. 1,2, but it is oval spherical also can to use hemisphere to arrive, and to further develop tangent plane by ellipse again be trapezoidal various valve plugs.

Valve plug and the inboard valve that is generally horn opening thereof in the utility model, can all be that metallic material is made, but generally speaking the two one of preferably with there being certain flexible nonmetallic material to make, as use flexible nonmetallic material to make the valve plug, method is the easiest.But also but image pattern 1 uses flexible material like that, makes the tubaeform valve position adjacent with the valve plug, when near position valve plug and the valve port the two one of when having certain elasticity nonmetallic material to make, the effect of sealing valve may be better when not inflating.

Valve plug bottom in the utility model air inlet lumen, do not use automatic-reset spring within like Fig. 1 like that, just must be advance gas gouging to the processing of the position of inner process is several in air inlet lumen bottom, as by the further passage of air inlet in tire in the air-inlet cavity, in order to avoid since when inflating the valve plug fall, blocking the bottom suction port influences air inlet.

The utility model is inflated to connect to chew with existing inflating and is chewed pipe and wait the position that is connected to answer machining screw, so that interconnect.

Claims

Structure is chewed in inflating of using on a kind of tire, have in it to inflate and chew pipe, air-inlet cavity, valve plug, movable center pillar and valve plug Returnning spring yet can be arranged, it is characterized in that: valve inside no longer is installed in inflation of tire is chewed pipe, but inflate chew pipe middle part than the major diameter air-inlet cavity in, installing one can move with uneven air pressure, chews the unidirectional valve plug of crossing gas thereby control to inflate.
