Description

Technical Field

[0001] This application relates to the field of tire valve technology, and in particular to a novel tire valve. Background Technology

[0002] The tire valve is a key component for inflating and maintaining tire pressure. It is usually made of metal or rubber and is fixed through mounting holes on the tire hub. The valve cap is one of the components and is screwed onto the end of the valve body by threads.

[0003] Valve caps are typically cylindrical in shape, with raised strips on their surface to increase friction. When twisting the valve cap, the user can easily detach it from the valve stem by using the friction of the raised strips. However, the cylindrical structure causes the force on the valve cap to be dispersed and not concentrated, making it more difficult for the operator to operate. When operating smaller valve caps, slippage can easily occur, making it impossible to unscrew the valve cap. Utility Model Content

[0004] This application provides a novel tire valve.

[0005] The novel tire valve provided in this application adopts the following technical solution:

[0006] A novel tire valve includes a valve body and a valve cap. The valve body includes a connecting portion and a fixing seat connected to the connecting portion. The outer periphery of the connecting portion is provided with an external thread. The valve cap has a mounting hole, and the mounting hole is provided with an internal thread that mates with the external thread. The valve cap is threadedly connected to the connecting portion. The outer side of the valve cap is also formed with multiple mounting surfaces facing different directions. Multiple protrusions are provided on the mounting surfaces, and the multiple protrusions are arranged parallel to each other along the width of the mounting surface.

[0007] Preferably, a positioning groove is formed on the fixing seat, and the connecting part is connected in the positioning groove; a positioning protrusion is formed at the lower end of the valve cap, and the positioning protrusion is embedded in the positioning groove.

[0008] Preferably, the upper end of the connecting part is provided with a flexible pad, which passes through the mounting hole and abuts against the valve cap.

[0009] Preferably, a first sealing gasket is provided at the end of the groove wall of the positioning groove, and the first sealing gasket is connected to the valve cap.

[0010] Preferably, a second sealing gasket is provided in the positioning groove, the second sealing gasket is located on the outer periphery of the connecting part and is connected to the positioning protrusion ring.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] 1. This application sets multiple mounting surfaces facing different directions, so that when the valve cap is rotated by the user, the force can be concentrated on the mounting surface in the direction of the user's finger force, and the valve cap can be opened by the friction with the ridge. In use, the user can easily unscrew the valve cap by the combined action of multiple mounting surfaces and ridge.

[0013] 2. By setting the first and second sealing gaskets, the airtightness is enhanced, making it difficult for gas inside the tire to leak out.

[0014] 3. By setting a flexible pad, excessive pressure on the inner end of the valve cap against the end of the connection part is avoided when the valve cap moves relative to the connection part through the engagement of the internal and external threads, thus preventing wear on the end of the connection part.

Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application provides a novel tire valve, such as Figures 1 to 6As shown, the valve includes a valve body 1 and a valve cap 2. The valve body 1 includes a connecting part 11 and a fixing seat 12 connected to the connecting part 11. The outer periphery of the connecting part 11 is provided with an external thread 111. The valve cap 2 forms a mounting hole 21. The mounting hole 21 is provided with an internal thread 211 that mates with the external thread 111. The valve cap 2 is threadedly connected to the connecting part 11. Multiple mounting surfaces 22 facing different directions are also formed on the outer side of the valve cap 2. Multiple protrusions 23 are provided on the mounting surfaces 22. The multiple protrusions 23 are arranged parallel to each other along the width of the mounting surfaces 22. By setting the mounting surfaces 22, the force on the valve cap 2 can be concentrated on the mounting surfaces 22 in the direction of the force applied by the user's fingers during the rotation of the valve cap 2. The valve cap 2 is opened by the friction with the protrusions 23. Compared with the prior art, the novel tire valve of this application allows the user to easily unscrew the valve cap 2 under the dual action of multiple mounting surfaces 22 and protrusions 23.

[0024] like Figure 3 As shown, a flexible pad 3 is provided at the upper end of the connecting part 11. The flexible pad 3 passes through the mounting hole 21 and abuts against the valve cap 2. In this way, the inner end of the valve cap 2 is not excessively pressed against the end of the connecting part 11 when it moves relative to the connecting part 11 through the engagement of the internal thread 211 and the external thread 111, which would cause excessive wear at the end of the connecting part 11.

[0025] like Figure 4 As shown, a positioning groove 121 is formed on the fixed base 12, and the connecting part 11 is connected to the positioning groove 121. A positioning protrusion ring 24 is formed at the lower end of the valve cap 2. The positioning protrusion ring 24 is embedded in the positioning groove 121. A first sealing gasket 4 is provided at the end of the groove wall of the positioning groove 121. The first sealing gasket 4 is connected to the valve cap 2. A second sealing gasket 5 is provided at the bottom of the groove of the positioning groove 121. The second sealing gasket 5 is located on the outer periphery of the connecting part 11 and is connected to the positioning protrusion ring 24. In this way, by setting the positioning groove 121 and the positioning protrusion ring 24 to fit together, the stability of the connection structure between the valve cap 2 and the valve body 1 is strengthened. By setting the first sealing gasket 4 and the second sealing gasket 5, the airtightness is enhanced, making it difficult for gas in the tire to leak out.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
