Description

Technical Field

[0001] This utility model relates to the field of valve stems, specifically a full copper vacuum tire valve stem for light trucks with a compensation function. Background Technology

[0002] The valve body is the passage for gas to enter the tire and can maintain the seal after the tire is inflated. All-copper valves have the characteristics of good high temperature resistance, good wear resistance and good thermal conductivity.

[0003] Existing valves do not have a compensation function. When over-inflation leads to tire overpressure, the tire cannot release gas in time, thus failing to achieve the pressure relief effect and easily causing the tire to explode. To address this issue, a full copper vacuum tire valve for light trucks with a compensation function is now provided. Utility Model Content

[0004] The purpose of this invention is to provide a full copper vacuum tire valve for light trucks with a compensation function, so as to solve the problems mentioned in the background art.

[0007] The inflation tube is installed at the top of the valve body, the air outlet is located at the bottom of the valve body, and the valve core is installed inside the inflation tube.

[0008] The compensation mechanism is located between the valve core and the inflation tube. The compensation mechanism includes an inner cylinder and a telescopic assembly.

Each movable block is fixed to the surface of the inner cylinder. The strip grooves and the movable blocks are sealed and slidably connected. Each first spring is installed on the top of a movable block. The other end of each first spring is fixedly connected to the inner wall of a strip groove.

[0011] As a further embodiment of this utility model: the sealing assembly includes an arc-shaped sealing gasket, an annular cavity and multiple inflatable components. The annular cavity is opened on the side of the limiting base near the snap-fit ​​groove. The arc-shaped sealing gasket is located on one side of the annular cavity and fixed to the surface of the limiting base. The arc-shaped sealing gasket and the inner cavity of the annular cavity are connected. The multiple inflatable components are fixed at equal intervals on the inner wall of the valve body. Each inflatable component is connected to the annular cavity.

[0012] As a further embodiment of this utility model: each inflation component includes an air inlet pipe, an air inlet, and a sealing block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The present invention relates to a full copper vacuum tire valve for light trucks with a compensation function. By setting a retractable inner cylinder, when the tire is over-inflated, the gas will drive the inner cylinder to move upward inside the inflation tube, increasing the space below the inner cylinder, so that the gas inside the tire can enter the valve body and release a small part of the pressure, which can play a role in pressure relief and buffering.

[0018] 2. The present invention relates to a full copper vacuum tire valve for light trucks with a compensation function. When the tire pressure decreases after the tire has been driven for a period of time, the inner cylinder can move downwards, and the space below the inner cylinder becomes smaller, which forces the gas back into the interior of the tire, thus achieving a compensation effect.

[0019] 3. This utility model discloses a full copper vacuum tire valve for light trucks with a compensation function. By setting an arc-shaped sealing gasket and an inflation component, when inflating the tire, the gas first enters the interior of the valve body, and then enters the tire again through the air outlet to achieve inflation. When the gas enters the interior of the valve body, it can push the sealing block to move away from the air inlet, so that some of the gas inside the valve body can enter the interior of the annular cavity and lift the arc-shaped sealing gasket. This allows the arc-shaped sealing gasket to make tight contact with the surface of the tire hub, improving the sealing effect. Attached Figure Description

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] The present invention provides the following preferred embodiments:

[0029] Example 1, as Figures 1-6 As shown, a full copper vacuum tire valve for light trucks with compensation function includes a valve body 11, an inflation pipe 12, an air outlet 13, a valve core 15, a compensation mechanism, and a sealing mechanism.

[0030] The inflation tube 12 is installed at the top of the valve body 11, the air outlet 13 is opened at the bottom of the valve body 11, and the valve core 15 is installed inside the inflation tube 12. The valve core 15 is the control valve for air intake and exhaust of the valve. The valve core 15 is existing technology and will not be described in detail here. In use, the gas that enters the valve body 11 through the valve core 15 flows out to the inside of the tire through the air outlet 13, thereby inflating the tire.

[0031] The compensation mechanism is located between the valve core 15 and the inflation tube 12. The compensation mechanism includes an inner cylinder 14 and a telescopic component. The inner cylinder 14 is slidably disposed inside the inflation tube 12. Specifically, the inner cylinder 14 and the inflation tube 12 are sealed and slidably connected. The valve core 15 is installed in the middle of the inner cylinder 14. The telescopic component is used to realize the movement of the inner cylinder 14. When over-inflation causes the tire to be over-inflated, the gas will drive the inner cylinder 14 to move upward inside the inflation tube 12, increasing the space below the inner cylinder 14, so that the gas inside the tire can enter the interior of the valve body 11, releasing a small portion of the pressure, which can play a pressure relief and buffering role. When the tire has been driven for a period of time and the tire pressure becomes low, the inner cylinder 14 can move downward, the space below the inner cylinder 14 becomes smaller, and the gas is squeezed back into the interior of the tire, which plays a compensation role.

[0032] The sealing mechanism is located on the surface of the valve body 11. The sealing mechanism includes a limiting base 20 and a clamping component. The limiting base 20 is fixed on the outside of the valve body 11. A snap-fit ​​groove 21 is formed on the side of the limiting base 20 away from the air outlet 13. The clamping component is located on the side of the limiting base 20 close to the snap-fit ​​groove 21.

[0033] When installing the valve stem, the valve stem body 11 is passed through the mounting hole on the wheel hub, and the limiting base 20 is abutted against one side of the wheel hub. The valve stem body 11 is installed using bolts. At the same time, the clamping component can increase the sealing effect between the limiting base 20 and the wheel hub, thereby improving the sealing effect of the valve stem.

[0034] like Figures 1-6 As shown, the telescopic assembly includes multiple strip grooves 16, multiple movable blocks 17, and multiple first springs 18. The multiple strip grooves 16 are equidistantly opened on the surface of the inflation tube 12. Each movable block 17 is slidably disposed inside a strip groove 16. Each movable block 17 is fixed to the surface of the inner cylinder 14. The strip grooves 16 and the movable blocks 17 are sealed and slidably connected. Each first spring 18 is installed on the top of a movable block 17. The other end of each first spring 18 is fixedly connected to the inner wall of a strip groove 16.

[0035] In the initial state, the moving block 17 is located at the bottom of the strip groove 16, and the first spring 18 is in the natural state. When the tire is over-inflated, the inner cylinder 14 drives the moving block 17 to move upward inside the strip groove 16, increasing the space below the inner cylinder 14 and playing a role in relieving pressure. At the same time, the first spring 18 is compressed.

[0036] When the tire pressure decreases after the tire has been driven for a period of time, the first spring 18 will cause the moving block 17 to move downward, thereby causing the inner cylinder 14 to move downward. The space below the inner cylinder 14 will become smaller, and the air will be squeezed back into the interior of the tire, thus compensating for the internal structure of the tire.

[0037] like Figures 1-6 As shown, the sealing assembly includes an arc-shaped sealing gasket 23, an annular cavity 24, and multiple inflatable components. The annular cavity 24 is opened on the side of the limiting base 20 near the snap-fit ​​groove 21. The arc-shaped sealing gasket 23 is located on one side of the annular cavity 24 and fixed to the surface of the limiting base 20. The arc-shaped sealing gasket 23 and the inner cavity of the annular cavity 24 are connected. Multiple inflatable components are fixed at equal intervals on the inner wall of the valve body 11. Each inflatable component is connected to the annular cavity 24.

[0038] The inflation component allows gas to enter the annular cavity 24, lifting the arc-shaped sealing gasket 23 so that it can come into contact with the surface of the wheel hub, thereby ensuring a tight seal between the arc-shaped sealing gasket 23 and the surface of the tire wheel hub and improving the sealing effect.

[0039] like Figures 1-6 As shown, each inflation component includes an air inlet pipe 25, an air inlet 26, and a sealing block 27. The air inlet pipe 25 is installed on the inner wall of the valve body 11. One end of the air inlet pipe 25 is connected to the annular cavity 24. The air inlet 26 is located at the end of the air inlet pipe 25 away from the annular cavity 24. The sealing block 27 slides inside the air inlet pipe 25. The outer diameter of the sealing block 27 is larger than the inner diameter of the air inlet 26.

[0040] like Figures 1-6 As shown, each intake pipe 25 has a vertical plate 28 fixed inside, and each vertical plate 28 has a sliding rod 29 slidably connected to it. One end of each sliding rod 29 is fixedly connected to a sealing block 27. A second spring 30 is sleeved on the sliding rod 29, and both ends of each second spring 30 are connected to the sealing block 27 and the vertical plate 28 respectively.

[0041] In the initial state, the second spring 30 is in the natural state, and the end of the blocking block 27 away from the slide bar 29 abuts against the end of the air intake pipe 25 near the air intake port 26, so that the blocking block 27 can block the air intake port 26.

[0042] When gas enters the valve body 11, it pushes the sealing block 27 to move away from the air inlet 26. The slide bar 29 slides on the vertical plate 28, and the second spring 30 is compressed. This allows some of the gas inside the valve body 11 to enter the annular cavity 24 and lift the arc-shaped sealing gasket 23, so that the arc-shaped sealing gasket 23 can make tight contact with the surface of the tire hub, thus improving the sealing effect.

[0043] like Figures 1-6 As shown, a cap 31 is fitted at the top of the inflation tube 12. The inflation tube 12 and the cap 31 are threaded together. The cap 31 can protect the end of the inflation tube 12 and prevent dust and other particles from entering the interior of the inflation tube 12 and causing blockage.

[0044] like Figures 1-6 As shown, the valve body 11, inflation tube 12, sealing cap 31, and limiting base 20 are all made of copper. The valve body 11, inflation tube 12, and limiting base 20 are integrally formed. Copper has the characteristics of good high temperature resistance, good wear resistance, and good thermal conductivity, which can effectively improve the strength of the valve and increase its service life.

[0045] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
