So above-mentioned is a kind of each portion's component of American gas-charging connection 100 provided by a preferred embodiment of the present invention
And its introduction of assembling mode, then its handling characteristics is described as follows again:
When being intended to be combined by the present invention with an American type valve 99 (as shown in Figure 4), first by preceding rotating cylinder 20 of the invention
American type valve screw hole 211 contacts (as shown in Figure 5) with the American type valve 99, and the forward of the preceding rotating cylinder 20 is gripped on by user
It is as shown in Figure 6 that the preceding rotating cylinder 20(is rotated on cylinder anti-slip section 23), make the external screw thread 991 and the preceding rotating cylinder in the American type valve 99
20 American type valve screw hole 211 is screw-coupled to until being closely connected to the gas nozzle seal ring 40.
Then, user rotates the rear rotating cylinder 30 again, connects the outer of mouth column 50 by internal screw thread 311 and this of the rear rotating cylinder 30
The effect of being spirally connected of screw thread 57, and this is made to connect the mouth of mouth column 50 52 toward 211 direction of American type valve screw hole close to the preceding rotating cylinder 20
Straight line axial movement, is butted in the American type valve 99 (as shown in Figure 7) until connecing.The limitation circumferential surface of mouth column 50 is connect by this simultaneously
56 with the limiting holes 112 of the limitation cylinder 10 are all in the restriction effect of non-circular section, and are avoided that this and connect mouth column 50 with this rear turn
30 synchronous rotaries of cylinder, can constantly axial advancement to keep this to connect mouth column 50.
In this way, just can be injected a gas into via the appendix 70 and stomata 51 in the American gas by charger
In mouth 99, to complete inflation operation.Due to the external screw thread 991 of the American type valve 99 and the American type valve screw hole of the preceding rotating cylinder 20
211 are spirally connected, it is thus ensured that the situation that the present invention will not be spontaneously decoupled during inflation with the American type valve 99, with
Maintain the smoothness of inflation.
Furthermore rotating cylinder 30 after user rotates this, so that this connects the mouth 52 of mouth column 50 toward close to the preceding rotating cylinder 20
It when 211 direction straight line of American type valve screw hole moves axially, is sheathed on this and connects the gas-tight ring 60 on mouth column 50, this can be located at and connect mouth column
Between 50 outer peripheral surface and 21 inner peripheral surface of functional hole of the preceding rotating cylinder 20, to form airtight conditions, and the smoothness of inflation can ensure that.
After completing to inflate operation, the preceding rotating cylinder 20 can be oppositely rotated, by the American type valve 99 and the present invention point
From the past direction far from the American type valve screw hole 211 of the mouth 52 for reversely rotating the rear rotating cylinder 30 thereafter this to be connect to mouth column 50
Axial movement, with the inflation operation of sharp next time.
So since the present invention is rotated using being located at homoaxial preceding rotating cylinder with American type valve, it is American to fix this
Gas nozzle, therefore operationally comparable intuitive, and mouth column will be connect connect and be butted on the American type valve, it is also to utilize rotation and American gas
Mouth is located at coaxial rear rotating cylinder to reach, all without additional operating space, user can carry out in small space
Operation, to promote operation ease of the invention.Furthermore due to simple structure of the invention, thus manufacturing cost and price energy
It reduces simultaneously, and its light and handy moulding is also easy to carry, is conducive to competitiveness in the market in fact.
It is above to be taken off, preferred embodiment only provided by the present invention, the implementation model being not intended to limit the invention
Enclose, all those skilled in the art according to the present invention carried out by equivalent change, should all belong to the range that is covered of the present invention.
