[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-4 As shown, a valve nozzle installation and positioning device comprises a wheel hub 1, a valve nozzle fixture 2, a connecting pipe 3, a conical limiting nut 4, a valve nozzle 5 and a thin nut 6. The valve nozzle 5 is installed on the inner wall of the wheel hub 1 and is locked by the thin nut 6. The valve nozzle 5 is clamped on the valve nozzle 5 so that the semicircular sheath 22 of the valve nozzle fixture 2 fits with the inflation tube of the valve nozzle 5, and the inflation tube opening of the valve nozzle 5 faces the inflation hole direction of the wheel hub 1. The connecting pipe 3 passes through the inflation hole of the wheel hub 1. The two arc-shaped quick plugs of the connecting pipe 3 are quickly connected with the arc-shaped quick plug groove holes on the valve nozzle fixture 2. The conical limiting nut 4 is connected to the connecting pipe 3 through a thread. By adjusting the conical limiting nut 4, the conical surface of the conical limiting nut 4 is fully contacted with the inflation hole of the wheel hub 1. When the thin nut 6 is tightened with a wind plate machine, the conical limiting nut 4 cannot shake, so that the valve nozzle 5 does not rotate, thereby realizing the valve nozzle positioning and installation.

[0018] A groove 21 consistent with the shape of the valve is provided on one side of the valve holder 2 . The groove 21 is designed according to the shape of the valve 5 to limit the rotation of the valve 5 .

[0019] The upper part of the valve holder is provided with a notch corresponding to the start of the valve inflation tube, and a semicircular sheath 22 designed according to the shape of the valve inflation tube is used to limit the swing of the valve inflation tube.

[0020] A limit block 23 designed according to the outer dimensions of the valve inflation tube is arranged on the upper part of the valve nozzle fixture to limit the swing of the valve nozzle inflation tube, and a quick-insert groove is arranged on the top of the limit block 23. The groove is arc-shaped and has a quick lock structure for use with the quick plug of the connecting tube 3.

[0021] An external thread is designed on the outside of the top end of the connecting tube 3, and two arc-shaped quick plugs are designed on the first end of the connecting tube 3. The two arc-shaped quick plugs are provided with a quick locking structure, which is used in conjunction with the valve holder 2 to limit the rotation of the valve holder 2. The connecting tube 3 passes through the wheel hub inflation hole and is used in conjunction with the conical limit nut 4 to limit the swing of the connecting tube 3.

[0022] The conical limiting nut 4 is designed with a cone at the bottom and is installed on the second end of the connecting tube 3 through a thread. The cone is in full contact with the hub inflation hole, limiting the conical limiting nut 4 from shaking, so that the connecting tube 3 is located in the middle position of the hub inflation hole.

[0023] The usage method of the utility model is as follows: when installing the valve 5, the valve clamp 2 clamps the valve 5, the connecting tube 3 is quickly connected with the valve clamp 2 through the wheel hub inflation hole, and interlocked, the conical limiting nut 4 moves up and down through the thread of the connecting tube 3, and the conical limiting nut 4 is rotated to make the conical surface of the conical limiting nut 4 fully contact with the wheel hub inflation hole, and when the thin nut 6 of the valve is tightened, the valve 5 does not rotate, and the position of the valve inflation tube and the wheel hub inflation hole remains fixed, so that the valve 5 is positioned and installed. After the thin nut 6 is tightened, the conical limiting nut 4 is screwed up, the connecting tube 3 is pulled out, and the valve clamp 2 is removed to complete the valve positioning installation.

[0024] The present utility model is not limited to the above-mentioned implementation modes, and anyone should be aware of the structural changes made under the inspiration of the present utility model.
