Abstract
The utility model discloses an auxiliary device of a tyre of a bicycle, a tricycle and a manpower vehicle, which is an anti-theft valve inside of a tyre. The utility model is characterized in that a standard hexagonal nut is additionally arranged on the base of the original valve inside structure, simultaneously the external form of the original air valve cap nut is modified to a hexagon from a circular straight burr, the nut and the cap nut are mutually caulked, and the anti-theft goal of the valve inside can be reached, so the utility model has the advantages of simple structure, convenient installation and operation, low increased cost and reliable anti-theft performance.
Description
The utility model relates to the auxiliary device of a kind of bicycle, three-wheel vehicle and rickshaw tire, particularly a kind of antitheft valve inside.
In China, along with the raising of living standards of urban and rural residents level, the universal face of bicycle, three-wheel vehicle and rickshaw is very extensive, and spreading speed is very fast, and particularly bicycle has become the indispensable instrument of people family.But in the prior art, the Tire Inflation System of these three kinds of cars is that the antitheft problem of valve inside does not also achieve a solution.Chinese patent is with CN2076507U disclosed " bicycle valve core anti-joyride device ", adopt an oblong sheet metal, the one end is curved annular be enclosed within on the valve nut, the other end is returned curved at the spoke place, uses screw, nut that sheet metal and valve nut and spoke is fastening again.Though this device than Chinese patent with CN87202432
Disclosed " tyre valve core anti-joyride device " is structurally simpler relatively, and cost also will hang down, but has increased sheet metal and screw, nut after all, causes on installing and using still not easily, and cost is still higher.
The purpose of this utility model be to provide a kind of structure very simple, install and use the antitheft valve inside of very convenient, with low cost, antitheft failure-free.
The technical solution that realizes the utility model purpose is: on the valve core print seat, set up a hexagonal nut near valve nut inboard, be that garden shape straight burr makes hexagon into for making the hexagonal nut set up and valve nut tighten mutually by original profile simultaneously with the valve nut, like this, valve inside can not be stolen without instrument.
Hexagonal nut is GB6172-86-M8.
The utility model is described further by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, in valve core print seat 1, insert valve inside 2, a hexagonal nut 4 of setting up is screwed on the valve core print seat 1 for GB6172-86-M8, again valve nut 3 is screwed on the valve core print seat 1, and valve inside 2 blocked, at last hexagonal nut 4 to 3 derotations of valve nut, make it be adjacent to valve nut 3, form interlocking.For the ease of screwing of valve nut 3, thus be that garden shape straight burr makes hexagon into its former profile, like this, after with spanner hexagonal nut 4 and valve nut 3 being wrenched mutually, even the big thief of strength can't steal valve inside without instrument at all.Application result shows, set up a nut after, do not influence inflation to tire.
In sum, it is very simple to the utlity model has structure, only needs to increase a little regular nut and just can realize antitheft, and install and use very convenient really, institute increases cost again seldom, and practicality is very strong, is applicable on bicycle, three-wheel vehicle and the rickshaw to apply.
