Abstract
The utility model relates to an effective multifunction air-filled connector, which can be used for inflating the mountain biking of the valve inside tyre for vehicle wheels of stem type and racing bicycles. The utility model comprises a screw joint and an adjusting core shaft; the adjusting core shaft is composed of an adjusting nut and an adjusting screw rod; the core part of the screw joint is provided with a stepped hole; the adjusting screw rod is screwed with the adjusting screw rod by the stepped hole of the screw joint; the utility model has the advantage of simple structure, and can be used for inflating a mountain biking and a racing bicycle; the utility model can also be used for inflating automobiles and motorcycle tyres.
Description
This reality has the novel structural development invention that relates to a kind of gas-charging connection that the bicycle, motor bike, the automobile inflating that adopt stem stem formula valve inside tire are used.
Existing, particularly old fashioned bicycle all adopts the tire of glue pipe type valve inside formula hermetically-sealed construction, and the characteristics of the tire of this structure are simple in structure, but poor air-tightness will inflate every several days, often is out of order again.So present mountain bike and racing car formula bike tyre all adopt similar automobile, the tire of the stem stem formula valve inside that motor bike is used, the advantage of this structure is that air-tightness is good, but must inflate it with special-purpose gas filled device; As with gas cylinder or air-pump inflating, then must cross joint and be used with existing limit shown in Figure 1.This crossover sub result of use is poor, when the tire sufficient gas, take away the geometrical clamp of inflator after, the nut a that must be fixed in time fast screws off, otherwise the high pressure air in the tire can outwards be released, if too shortly during inflation at this moment cause underinflationly, then influence is ridden; Too full as inflation, grasp badly, inner tube is exploded.
The purpose of this utility model provides a kind of high-efficiency multi-function gas-charging connection, and it can also be used for the inflation of tire to motor bike and automobile fast, efficient, safely to mountain bike, the inflation of racing car formula bicycle.
Structure of the present utility model is seen shown in the accompanying drawing 2, it is characterized in that this gas-charging connection comprises a screw connection and an adjusting mandrel; Wherein the top of screw connection is barrel-contoured cylinder, and portion is the holding part of frustum, and the bottom is a trumpet-shaped spiral interface, and screw connection inside is shaped on big-and-middle the little stepped hole in a two; Regulating mandrel is made up of adjusting nut, adjusting screw(rod); Trumpet-shaped spiral interface one end from screw connection of adjusting screw(rod) inserts the back and screws at screw connection tubular column one end with the adjusting nut.
The utility model advantage compared with prior art is easy to manufacture, easy to use, with gas cylinder or air pump to the tire sufficient gas after, can at leisure it be screwed off and can not cause charging into the high pressure gas leakage of tire, thereby can prevent that tire or underinflation influence from riding, or inflate the excessive defective that causes the tire inner tube blast.
Accompanying drawing has been described prior art constructions and embodiment of the present utility model,
Fig. 1 is the cross-sectional schematic of prior art constructions,
Fig. 2 is the structure cross-sectional schematic of the utility model embodiment.
In accompanying drawing 2, forming screw connection 1, the adjusting mandrel 2 usefulness metals of this gas-charging connection makes, wherein cylinder is made on the top of screw connection 1, a frustum holding part is made at the middle part, these two parts grip usefulness for the clip of gas cylinder, a trumpet-shaped spiral interface is made in the bottom, be shaped on negative thread in the interface and be spun on fixing using on the stem stem formula valve inside outer tube wall for screw connection 1, packing seal 3 in the interface is used to strengthen sealing effectiveness, and screw connection inside is shaped on big-and-middle the little stepped hole in a two; After the adjusting screw(rod) 2-2 that form to regulate mandrel 2 inserts in the horn-like spiral interface one end stepped hole in screw connection 1 bottom, screw in the stepped hole of screw connection 1 tubular column one end with adjusting screw(rod) 2-1, and can change the length of the best of regulating mandrel 2, with the result of use that guarantees that this practicality is new.
Principle of work of the present utility model is such: the screw connection 1 of high-efficiency multi-function gas-charging connection is tightened on the stem stem formula valve inside tracheae outer tube wall that needs gas filed tire, geometrical clamp with the high-pressure pump appendix is clamped in the screw connection 1 top tubular column of gas-charging connection and the retaining part of middle part frustum again, at this moment because geometrical clamp is clipped in the air outlet parts at tubular column position, it is descending that mandrel 2 stem stem descending and that promote in the stem stem valve inside on the tire is regulated in compressing, open gas fill port, if gas cylinder has high pressure gas to send into thereupon, just begun inflation to tire; By the time when tire is charged to the expection required pressure, just can take off the geometrical clamp of gas cylinder, stop inflation, because taking off of geometrical clamp clip, stem stem on the tire in the stem stem formula valve inside is subjected to the effect of the interior high-pressure gas pressure that is filled of tire, jack-up is regulated mandrel 2, also just seal the valve inside of tire, thereby blocked the passage that fills high pressure gas leakage in the tire, the cyclist can be taken off geometrical clamp and screw off gas-charging connection in a rush ground quickly, only need to operate calmly, just can reach the aforesaid purpose of the utility model.Close at some special field boundary, by means of the utility model, use gas cylinder, electric air pump puts on the air to automobile or motor cycle tire, and does not need special-purpose gas-charging connection.Just can guarantee charge-air mass, thereby be a kind of desirable instrument of inflating tyres of vehicles.
