Description

Technical Field

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

[0002] The valve is a key component mounted on the wheel hub for inflating tires and maintaining tire pressure. When it is open, it allows air to enter the space of a tubeless tire or inner tube. When it is closed, it seals and retains the air to generate pressure, preventing air from escaping from the tire or inner tube.

[0003] After the valve stem is inserted into the mounting hole on the wheel hub, baffles are usually installed on both the inner and outer sides of the wheel hub to fix the valve stem, and the valve stem is closed by a valve cap. The valve caps on the market are usually connected to the end of the valve stem by threads. When the valve stem needs to be opened, the valve cap is screwed on. However, screwing will apply a circumferential force to the valve stem body. After the valve stem is opened and closed by the valve cap many times, the applied force will gradually weaken the stability of the connection structure between the baffle and the wheel hub, causing the valve stem to loosen, which in turn affects the seal between the valve stem and the wheel hub. Utility Model Content

[0004] This application provides a bent valve stem with better stability.

[0005] The bent valve stem provided in this application adopts the following technical solution:

[0006] A bent valve stem includes a main body comprising a first connecting segment, a second connecting segment, a third connecting segment, a fourth connecting segment, and a fifth connecting segment connected sequentially. The first, second, third, fourth, and fifth connecting segments form an air passage, within which a valve core is disposed. A valve cap is threaded onto the first connecting segment. The second connecting segment is inserted into a mounting hole in a wheel hub. The third connecting segment is disposed on the outer side of the wheel hub. The first, second, and third connecting segments are coaxially arranged. The third connecting segment and the fourth connecting segment are distributed at an acute angle, with the fourth connecting segment extending towards the wheel hub. The fifth connecting segment and the fourth connecting segment are distributed at an obtuse angle, with the fifth connecting segment extending away from the wheel hub. The junction of the fourth and fifth connecting segments abuts against the inner side of the wheel hub.

[0007] Preferably, the second connecting section is provided with an outer baffle and an inner baffle. The outer baffle is used to be disposed on the outer side of the wheel hub, and the inner baffle is used to be disposed on the inner side of the wheel hub. The diameter of the third connecting section is larger than the diameter of the mounting hole, and the third connecting section is used to abut the inner baffle against the inner side of the wheel hub.

[0008] Preferably, a fastening sleeve is also provided on the outer side of the first connecting segment, and the fastening sleeve abuts against the outer baffle.

[0009] Preferably, a sealing gasket is also provided on the outer side of the first connecting section, the sealing gasket being located between the fastening sleeve and the valve cap, and the valve cap abutting against the sealing gasket.

[0010] Preferably, the airway includes a first bend and a second bend, and the inner sides of the first bend and the second bend are arc-shaped structures.

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

[0012] 1. This application increases the friction between the main body and the hub by setting the end of the fourth and fifth connecting sections to abut against the inner side of the hub, making the main body less likely to rotate due to the rotation of the valve cap, thereby ensuring the stability of the connection structure between the main body and the hub. Since the fifth connecting section extends away from the hub, the air passage is less likely to be blocked by the hub or tire when delivering gas, thus ensuring the efficiency of gas delivery.

[0013] 2. By setting the inner sides of the first and second bends to be arc-shaped, gas can be transported more efficiently. Attached Figure Description

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] This application provides a bent valve stem, such as Figure 1 and Figure 2 As shown, it includes a main body 1, which includes a first connecting segment 11, a second connecting segment 12, a third connecting segment 13, a fourth connecting segment 14, and a fifth connecting segment 15 connected in sequence.

[0019] The first connecting section 11 is threadedly connected to a valve cap 2. The first connecting section 11 has external threads, and the valve cap 2 has internal threads. The valve cap 2 is fixed to the first connecting section 11 by the engagement of the external and internal threads. The maximum cross-sectional diameter of the external thread and the second connecting section 12 is not greater than the cross-sectional diameter of the mounting hole in the wheel hub. The second connecting section 12 is used to pass through the mounting hole in the wheel hub, and its length is greater than the thickness of the mounting hole. Along the outer side of the second connecting section 12, from the third connecting section 13 to the valve cap 2, an inner baffle 5, an outer baffle 4, a fastening sleeve 6, and a sealing gasket 7 are sequentially and coaxially arranged. The diameters of the outer baffle 4, fastening sleeve 6, and sealing gasket 7 gradually decrease. The fastening sleeve 6 abuts against the outer baffle 4 to press the outer baffle 4 against the outside of the wheel hub. The sealing gasket 7... The diameter is smaller than that of the valve cap 2. The valve cap 2 is pressed onto the sealing gasket 7 through a threaded connection, thereby applying pressure to the fastening sleeve 6 and the outer baffle 4, reinforcing the connection structure between the outer baffle 4 and the wheel hub. The inner baffle 5 is located on the inner side of the wheel hub. The diameter of the third connecting section 13 is larger than that of the mounting hole. The third connecting section 13 is used to abut the inner baffle 5 against the inner side of the wheel hub. The first connecting section 11, the second connecting section 12 and the third connecting section 13 are coaxially arranged. The third connecting section 13 and the fourth connecting section 14 are distributed at an acute angle, and the fourth connecting section 14 extends towards the wheel hub. The fifth connecting section 15 and the fourth connecting section 14 are distributed at an obtuse angle, and the fifth connecting section 15 extends away from the wheel hub. The joint of the fourth connecting section 14 and the fifth connecting section 15 is used to abut against the inner side of the wheel hub.

[0020] The first connecting section 11, the second connecting section 12, the third connecting section 13, the fourth connecting section 14, and the fifth connecting section 15 form an air passage 16 for conveying gas. An air valve core 3 is provided inside the air passage 16. The air passage 16 includes a first bend 161 and a second bend 162. The first bend 161 is the interior of the junction of the third connecting section 13 and the fourth connecting section 14, and the second bend 162 is the junction of the fourth connecting section 14 and the fifth connecting section 15. The inner sides of the first bend 161 and the second bend 162 have an arc-shaped structure to facilitate more efficient gas transmission.

[0021] In the specific installation process of the bent valve of this application, the outer baffle 4 is first coaxially attached to the outer surface of the hub. Then, the first connecting section 11 and the second connecting section 12 are sequentially inserted into the mounting holes of the hub along the direction from the outer surface to the inner surface until the end of the third connecting section 13 abuts against the outer baffle 4. The ends of the joints of the fourth connecting section 14 and the fifth connecting section 15 abut against the inner side of the hub. Then, the inner baffle 5, the fastening sleeve 6, and the sealing gasket 7 are sequentially arranged on the second connecting part along the direction from the outer surface to the inner surface of the hub. Finally, the valve cap 2 is tightened. The outer baffle 4 is fixed to the outside of the wheel hub, thus completing the installation. When it is necessary to open the bent valve, the valve cap 2 is screwed on. At this time, since the ends of the fourth connecting section 14 and the fifth connecting section 15 abut against the inside of the wheel hub, the friction between the main body 1 and the wheel hub is increased, making the main body 1 less likely to rotate due to the rotation of the valve cap 2, thereby ensuring the stability of the connection structure between the main body 1 and the wheel hub. Since the fifth connecting section 15 extends away from the wheel hub, the air passage 16 is less likely to be blocked by the wheel hub or tire when delivering gas, thus ensuring the efficiency of gas delivery.

[0022] 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.
