Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to an anti-lost valve nozzle. Background Art

[0002] A Presta valve is a valve installed on a French bicycle inner tube, used to add or release air to the inner tube. Presta valves are usually thinner and longer than valves on ordinary bicycles, with a smaller inner diameter and a small screw-on nut on the top. Before starting to inflate, you need to unscrew the small nut on the Presta valve. After inflation, you need to tighten the small nut on the Presta valve to prevent gas leakage.

[0003] Chinese patent CN219062548U discloses a valve nozzle, including a valve nozzle and an air intake mechanism, wherein a connecting column is fixedly connected to the upper surface of the valve nozzle, a fixing column is fixedly installed on the upper surface of the connecting column, a protective cover is threadedly connected to the upper surface of the fixing column, an air intake mechanism is arranged on the inner surface of the fixing column, and a mounting mechanism is arranged on the lower surface of the connecting column.

[0004] However, the protective cover of the patent is threadedly connected to the fixing column. When inflating the valve, the protective cover needs to be twisted to completely separate the protective cover from the fixing column before the valve can be inflated. However, the protective cover is small in size and is very easy to lose.

[0005] Based on this, the utility model designs an anti-lost valve nozzle to solve the above problem. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides an anti-lost valve nozzle.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] An anti-lost valve nozzle, comprising a valve nozzle assembly;

[0009] The valve nozzle assembly comprises a valve core seat, an air pressure cover, a valve body, a valve core, a small nut and a limit block. The valve body is fixedly connected to the center of the upper end of the valve core seat. The air pressure cover is sleeved on the valve body and is threadedly connected to the valve body. The valve core is embedded in a circular hole at the upper end of the valve body and is threadedly connected to the valve body. The upper end of the valve core is threadedly connected with a small nut. The upper outer edge of the valve core is fixedly connected to the limit block. The limit block is formed by the top of the valve core being deformed by force.

[0010] A dustproof component is installed on the valve mouth component.

[0011] Furthermore, the dustproof assembly is connected to the valve body.

[0012] Furthermore, the dustproof component includes a cover, a dustproof part, a magnetic component and a first protrusion. The left side of the upper end of the dustproof part is hinged to the left end of the cover by an elastic hinge, the upper side of the right end of the dustproof part and the right end of the cover are fixedly connected with the first protrusion, the inner ends of the first protrusions are fixedly connected with the magnetic components, and the first protrusion on the upper side is magnetically connected to the first protrusion on the lower side through the magnetic component.

[0013] Furthermore, the inner wall of the lower end of the dustproof piece is threadedly connected to the outer wall of the upper end of the valve body.

[0014] Furthermore, a sealing gasket is fixedly connected to the lower end of the cover.

[0015] Furthermore, the dustproof part is a hollow cylindrical shape.

[0016] Furthermore, the diameter of the cover is larger than the outer diameter of the upper end of the dustproof member.

[0017] Furthermore, the magnetic component is a magnet.

[0018] The utility model has the following technical effects:

[0019] When the utility model is used, the dustproof component is first opened, and then the small nut is unscrewed. Under the blocking effect of the limit block, the small nut will not be separated from the valve core, so as to prevent the small nut from being accidentally separated from the valve core when twisting. Moreover, the small nut is small in size and easy to be lost. An air pump or an adapter is connected to the valve mouth, and air is inflated into the tire through the pump or the air cylinder. After the air is inflated, the air mouth nut is tightened to prevent gas leakage, and then the dustproof component is closed to prevent dust from entering the valve core.

[0020] The cover is rotated in the opposite direction under the elastic action of the hinge joint of the elastic hinge to be reset, and the cover drives the first protrusion connected thereto to rotate, and the first protrusion drives the magnetic assembly connected thereto to rotate, until the two magnetic assemblies are sucked together to prevent dust from entering the valve core.
