Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a pressure-type valve stem with an adjustable installation angle. Background Technology

[0002] A valve is a separate valve body device that opens to allow air into the space of a tubeless tire or inner tube, then automatically closes and seals to retain the air pressure and prevent it from escaping. Except for solid tires, all other tires or inner tubes that require inflation need this device. Ordinary valves are not compatible with vehicles equipped with tire pressure sensors, and some valves that are compatible with tire pressure sensors often have a fixed installation angle, which limits installation options. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides an adjustable-angle clamping valve, comprising a valve body, a valve core assembly, a dust cap, a clamping cap, and a sensor fixing screw. The valve body includes a first connecting portion and a second connecting portion that are interconnected. A first angle is formed between the central axis of the first connecting portion and the central axis of the second connecting portion. The valve core assembly is accommodated in the first connecting portion. The upper end of the first connecting portion is threadedly connected to the dust cap. The clamping cap is sleeved on the second connecting portion and threadedly connected to the second connecting portion. The bottom of the second connecting portion is provided with a first threaded hole and a second threaded hole that are interconnected. A second angle is formed between the central axis of the first threaded hole and the central axis of the second threaded hole. The sensor fixing screw is adapted to be threadedly connected to either the first threaded hole or the second threaded hole.

[0004] Optionally, it also includes a sealing element, which is sleeved on the second connecting part. The second connecting part is provided with a limiting groove. The bottom of the sealing element is provided with a flange, which is limited in the limiting groove. The upper end of the sealing element is adapted to abut against the compression cap.

[0005] Optionally, the valve core assembly includes a first connector, a second connector, a valve needle, and a spring. The first connector and the second connector are rotatably connected to form a through-cavity. The valve needle slides through the cavity, and the spring is sleeved on the valve needle and accommodated in the cavity.

[0006] Optionally, a limiting seat is fixedly connected to the bottom of the air nozzle needle, and a first sealing ring is provided on the limiting seat. The first sealing ring is adapted to abut against the bottom of the second connector.

[0007] Optionally, the air nozzle needle is provided with a pressing block, and the upper and lower ends of the spring respectively abut against the pressing block and the inner wall of the second connecting member, and the pressing block is accommodated in the receiving cavity.

[0008] Optionally, the first connector is threaded to the inner wall of the air nozzle body, the inner wall of the air nozzle body is provided with a limiting surface, and the outer wall of the second connector is provided with a rubber ring, the rubber ring abutting against the limiting surface.

[0009] Optionally, the upper end of the first connector is provided with a rotating part, which facilitates the rotational installation of the first connector. The rotating part is provided with a through hole, and the air nozzle needle moves up and down through the through hole.

[0010] Optionally, the first included angle ranges from 110 to 130°, and the second included angle ranges from 35 to 55°.

[0011] Optionally, the bottom of the second connecting part is provided with a third threaded hole, which connects the first threaded hole and the second threaded hole simultaneously.

[0012] Optionally, the range of the third included angle is 35-55°.

[0013] Compared to existing technologies, the adjustable-angle compression valve of this invention features a valve body whose bottom is suitable for connecting a tire pressure sensor. The sensor fixing screw can be connected via either the first or second threaded hole, allowing for more installation angle options and improved compatibility. Simultaneously, the first included angle between the first and second connecting parts adapts to the rim angle during rim assembly, resulting in a better connection. Furthermore, by coordinating the valve core assembly, dust cap, and valve body, when the tire is inflated, the external inflation device presses down on the valve core assembly, opening a channel at the bottom of the assembly to allow air to enter the tire. When the tire pressure reaches a threshold, the valve core assembly resets, closing the channel to prevent further air inflow. This design offers stable and reliable operation, long service life, low cost, and excellent high-pressure resistance. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0023] This utility model embodiment provides a pressure-type valve stem with an adjustable installation angle, combined with Figure 1-4 As shown, the device includes a valve body 1, a valve core assembly, a dust cap 9, a clamping cap 2, and a sensor fixing screw 4. The valve body 1 includes a first connecting part 11 and a second connecting part 12 that are interconnected. A first included angle α is formed between the central axis of the first connecting part 11 and the central axis of the second connecting part 12. The valve core assembly is accommodated in the first connecting part 11. The upper end of the first connecting part 11 is threadedly connected to the dust cap 9. The clamping cap 2 is sleeved on the second connecting part 12 and threadedly connected to the second connecting part 12. The bottom of the second connecting part 12 is provided with a first threaded hole 121 and a second threaded hole 122 that are interconnected. A second included angle β is formed between the central axis of the first threaded hole 121 and the central axis of the second threaded hole 122. The sensor fixing screw 4 is adapted to be threadedly connected to the first threaded hole 121 or the second threaded hole 122.

[0024] like Figure 1 As shown, in this embodiment, the bottom outer end face of the air valve body 1 is an arc structure. The tire pressure sensor is installed in conjunction with the arc structure and can be rotated around the arc structure to be adjusted to the optimal installation position according to the actual assembly state.

[0025] The valve body 1 has a positioning plane on its bottom side wall for engaging a wrench. When the valve is tightened onto the rim by rotating the clamping cap 2, the positioning plane is held in place by a wrench to prevent the valve body from rotating synchronously with the clamping cap 2. This achieves the required assembly torque and allows for precise positioning of the first threaded hole 121 and the second threaded hole 122. The interconnected design of the first connecting part 11 and the second connecting part 12 ensures that the installation of the tire pressure sensor does not affect the valve's inflation / deflation process.

[0026] The adjustable-angle compression valve of this invention features a valve body 1 whose bottom is suitable for connecting a tire pressure sensor. The sensor fixing screw 4 can be connected via either the first threaded hole 121 or the second threaded hole 122, allowing for more installation angle options and improved compatibility. Simultaneously, the first included angle α between the first connecting part 11 and the second connecting part 12 can adapt to the rim angle during rim assembly, resulting in a better connection. Furthermore, by coordinating the valve core assembly, dust cap 9, and valve body 1, when the tire is inflated, the external inflation device presses down on the valve core assembly, opening a channel at the bottom of the assembly to allow gas to enter the tire. When the tire pressure reaches a threshold, the valve core assembly resets, closing the channel to prevent further gas inflow. This design offers stable and reliable structure, long service life, low cost, and excellent high-pressure resistance.

[0027] Optionally, the adjustable installation angle pressure valve further includes a sealing element 3, which is sleeved on the second connecting part 12. The second connecting part 12 is provided with a limiting groove. The bottom of the sealing element 3 is provided with a flange 31, which is limited in the limiting groove. The upper end of the sealing element 3 is adapted to abut against the pressure cap 2.

[0028] like Figure 2 As shown, in this embodiment, the flange 31 is used to limit the axial movement distance of the seal 3. When the pressure cap 2 is rotated, the upper end of the seal 3 abuts against the bottom of the pressure cap 2 to limit the axial movement distance of the pressure cap 2.

[0029] like Figure 3 and 4As shown, optionally, the valve core assembly includes a first connector 5, a second connector 6, a valve needle 7, and a spring 8. The first connector 5 and the second connector 6 are rotatably connected to form a through-cavity. The valve needle 7 is slidably inserted into the cavity, and the spring 8 is sleeved on the valve needle 7 and accommodated in the cavity.

[0030] Optionally, the bottom of the air nozzle needle 7 is fixedly connected to a limiting seat 71, and the limiting seat 71 is provided with a first sealing ring 72, which is adapted to abut against the bottom of the second connecting member 6.

[0031] like Figure 3 and 4 As shown, in this embodiment, when the tire is inflated, the valve needle 7 moves downward under the pressure of the external inflation device, and the valve needle 7 drives the limiting seat 71 to move downward together. At this time, the bottom of the limiting seat 71 and the second connecting member 6 forms a channel for gas to flow. The gas flows downward through the accommodating cavity and the channel until it enters the tire.

[0032] When the air pressure inside the tire reaches the threshold, the valve needle 7 returns to its original position under the action of the spring 8. At this time, the limit seat 71 moves upward along with the valve needle 7 until the bottom of the first sealing ring 72 and the second connecting piece 6 seals and abuts to close the channel, prevent gas from continuing to flow in, and avoid excessive air pressure inside the tire causing a blowout.

[0033] Optionally, the air nozzle needle 7 is provided with a pressing block 73, and the upper and lower ends of the spring 8 respectively abut against the pressing block 73 and the inner wall of the second connecting member 6, and the pressing block 73 is accommodated in the receiving cavity.

[0034] like Figure 3 and 4 As shown, in this embodiment, when the air nozzle needle 7 moves downward, the pressing block 73 presses the spring 8, causing the spring 8 to accumulate a return force. When the air pressure is balanced, the spring 8 drives the pressing block 73 to move upward, so that the air nozzle needle 7 remains in its original position. At the same time, the pressing block 73 abuts against the top wall of the accommodating cavity to limit the rebound distance of the air nozzle needle 7.

[0035] Optionally, the first connector 5 is threadedly connected to the inner wall of the air nozzle body 1, the inner wall of the air nozzle body 1 is provided with a limiting surface, and the outer wall of the second connector 6 is provided with a rubber ring 61, the rubber ring 61 abutting against the limiting surface.

[0036] like Figure 3 and 4 As shown, in this embodiment, the limiting surface is inclined inward from top to bottom, and the rubber ring 61 abuts against the limiting surface. The rubber ring 61 increases the friction between the rubber ring and the air nozzle body 1, so that the position of the second connecting piece 6 is more stable.

[0037] Optionally, the upper end of the first connector 5 is provided with a rotating part 51, which facilitates the rotational installation of the first connector 5. The rotating part 51 is provided with a through hole 511, and the air nozzle needle 7 moves up and down through the through hole 511.

[0038] like Figure 4 As shown, in this embodiment, the user can use a tool to rotate the rotating part 51 to facilitate threading the first connector 5 and the air nozzle body 1 together. Figure 2 As shown, the dust cap 9 is provided with a second sealing ring 91, and the upper end of the air nozzle body 1 abuts against the second sealing ring 91. When the dust cap 9 and the air nozzle body 1 are threadedly connected, the second sealing ring 91 acts as a buffer to prevent hard friction between the upper end of the air nozzle body 1 and the inner top wall of the dust cap 9, thus preventing damage.

[0039] Optionally, the first included angle α ranges from 110 to 130°, and the second included angle β ranges from 35 to 55°.

[0040] like Figure 2 As shown, in this embodiment, the first included angle α is 120° and the second included angle β is 45°.

[0041] Optionally, the bottom of the second connecting part 12 is provided with a third threaded hole 123, which simultaneously connects the first threaded hole 121 and the second threaded hole 122. A third included angle γ is formed between the central axes of the third threaded hole 123 and the second threaded hole 122. The sensor fixing screw 4 is adapted to be threadedly connected to the first threaded hole 121 or the second threaded hole 122.

[0042] like Figure 2 As shown, in this embodiment, the first threaded hole 121 and the third threaded hole 123 are symmetrical with respect to the second threaded hole 122.

[0043] Optionally, the range of the third included angle γ is 35-55°.

[0044] like Figure 2 As shown, in this embodiment, the third included angle γ is 45°.

[0045] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
