Abstract

The utility model relates to a pneumatic tire using the air charging nozzle for tire which is used for pumping the tire. A piston and an adjustable rod which are arranged at the inside of the nozzle body are screwed by threads, and the total length of the piston and the adjustable rod can be adjusted. A spring is sheathed on the adjustable rod, and one end of the spring is limited on the inner wall of the nozzle body. The nozzle body can be screwed on the existing air nozzle of a vehicle and pumped by a pump device of the clamping type after sealing. The adjustable rod can automatically push the valve inside opened, and the compressed air flows into the tire from the inner hole of the piston. The valve inside can automatically close when the pumping is finished. The utility model has the advantages of easy inflation, and little resistance for pumping.

Description

Air charging nozzle for tire

The utility model relates to a kind of tire of using to inflation of tire and connects mouth with inflation.

Existing self-propelled vehicle relies on the direct unseat the valve core inflation of air pressure when inflation, pressurized air is when entering tire, and suffered resistance is bigger.

The purpose of this utility model is to provide a kind of tire to connect mouth with inflation, this kind device and adapted folder formula gas filled device again after valve on the existing automobile tyre is connected, can make the valve inside self-opening, gas charge into resistance force diminishes, the inflation back valve inside that finishes is promptly closed voluntarily.

The purpose of this utility model is achieved in that the mouth body that the two ends internal diameter does not wait in chamber of design, an end bigger at internal diameter has negative thread, the corner that borders in two footpaths is provided with a seal ring, at the less end of internal diameter a piston and adjust bar are arranged, piston screws on adjust bar with screw thread, and can regulate the total length of both combinations as required, piston some expose at mouth external, a spring housing is on adjust bar, the one end is placed restrictions on the inwall of mouth body, after relying on screw thread to screw sealing, the valve on this device and the existing self-propelled vehicle adopts folder formula gas filled device again, the Clamping force of clip makes piston promote adjust bar and backs down the porthole core, pressurized air enters tire by piston inner hole, after inflation finished, removal folder formula gas filled device restored to the original state under the tension force of spring, this moment, valve inside was promptly closed voluntarily, thereby reached the purpose of this utility model.

The utility model compared with prior art has inflation easily, the little characteristics of inflation resistance.

Detailed enforcement of the present utility model will provide in conjunction with the accompanying drawings:

Fig. 1 is tire connects mouth with inflation a constructional drawing;

Fig. 2 is the A-A section-drawing of Fig. 1.

If the mouth body (2) that the two ends internal diameter does not wait in chamber of Meter, an end bigger at internal diameter has negative thread, the corner that borders in two footpaths is provided with a seal ring (5), at the less end of internal diameter one piston (1) and adjust bar (3) are arranged, piston (1) screws on adjust bar (3) with screw thread, and can regulate the total length of both combinations as required, some exposes piston (1) outside mouth body (2), a spring (4) is enclosed within on the adjust bar (3), and the one end is placed restrictions on the inwall of mouth body (2).

After relying on screw thread to screw sealing, the valve on this device and the existing self-propelled vehicle adopts folder formula gas filled device again, the Clamping force of clip makes piston (2) promote adjust bar (3) and the unseat the valve core, pressurized air enters tire by piston (1) endoporus, after inflation finishes, removal folder formula gas filled device, restore to the original state under the tension force of spring (4), this moment, valve inside was promptly closed voluntarily.

The utility model also can be shaped on outside thread on the part outer wall of mouth body (2), can screw dust cap, enters piston (1) to prevent dust.

Claims

1, a kind of tire connects mouth with inflation, feature of the present utility model is that the mouth body (2) that the two ends internal diameter does not wait in the chamber is arranged, an end bigger at internal diameter has negative thread, the corner that borders in two footpaths is provided with a seal ring (5), at the less end of internal diameter one piston (1) and adjust bar (3) are arranged, piston (1) screws on adjust bar (3) with screw thread, some exposes piston (1) outside mouth body (2), a spring (4) is enclosed within on the adjust bar (3), and the one end is placed restrictions on the inwall of mouth body (2).

2, tire according to claim 1 connects mouth with inflation, it is characterized in that being shaped on outside thread on the part outer wall of mouth body (2).
