Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an anti-aging, high-pressure resistant all-copper vacuum tire valve for light trucks. Background Technology

[0002] A valve on a tubeless tire is a device installed on the tire rim for inflation and deflation. It allows gas to pass through and be injected into the tire to maintain proper tire pressure and ensure driving safety. The tubeless tire valve is an important component of the tire and plays a vital role in driving safety.

[0003] During vehicle operation, the valve stem of a tubeless tire is a crucial component, and its function and integrity play an indispensable role in maintaining proper tire pressure and ensuring driving safety. However, since vehicles often travel on various road surfaces, tires inevitably suffer from continuous impacts and vibrations from the road surface. Over time, this constant bumping can adversely affect the valve cap, especially when the tightness between the cap and the valve stem body gradually weakens due to repeated vibrations. Loosening or even detachment of the cap can damage the original sealing performance of the valve stem.

[0004] Therefore, it is necessary to design an anti-aging, high-pressure resistant all-copper vacuum tire valve for light trucks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-aging, high-pressure resistant all-copper vacuum tire valve for light trucks.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An anti-aging, high-pressure resistant all-copper vacuum tire valve for light trucks includes a valve body, a connector at one end of the valve body, a valve cap screwed onto the end of the valve body away from the connector, an annular groove at the end of the valve body away from the connector, a sealing mechanism within the annular groove, a pull rod extending through the side of the valve cap, and a limit mechanism on the pull rod.

[0008] Preferably, the sealing mechanism includes an elastic airbag ring disposed on the inner wall of the annular groove, an annular relief groove is provided on the outer wall of the connection between the valve body and the valve cap, a sealing airbag ring is provided on the inner wall of the annular relief groove, the sealing airbag ring and the elastic airbag ring are connected by a conduit, and an annular sealing groove adapted to the sealing airbag ring is provided on the inner wall of the valve cap.

[0009] Preferably, the inner wall of the annular sealing groove is symmetrically provided with slots, and the outer wall of the sealing airbag ring is symmetrically fixed with a locking block that matches the slot.

[0010] Preferably, both the card block and the card slot have a square cross-sectional shape.

[0011] Preferably, the limiting mechanism includes a pressure plate fixedly installed on one end of the pull rod located inside the mouth cap, a spring is fitted on the pull rod, a guide groove is provided on the inner wall of the mouth cap, and two limiting grooves are provided on the inner wall of the mouth cap, and the two limiting grooves are respectively connected to the two ends of the guide groove.

[0012] Preferably, a limiting block adapted to the guide groove and the limiting groove is fixedly installed on the outer wall of the pressure plate, and a sealing gasket is provided on the side of the pressure plate opposite to the valve body.

[0013] Preferably, a pull plate is fixedly installed at one end of the pull rod located on the outside of the mouth cap.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting an annular groove and sealing mechanism, when the valve cap is tightened onto the valve body, the gas in the elastic airbag ring is squeezed into the sealing airbag ring, causing it to expand and tightly embed into the annular sealing groove on the inner wall of the valve cap. This not only significantly improves the sealing performance between the valve cap and the valve body and effectively prevents gas leakage, but also further enhances the stability and safety of the connection through the cooperation between the locking block on the outer wall of the sealing airbag ring and the locking groove on the inner wall of the annular sealing groove, reducing the risk of the valve cap falling off during driving.

[0016] 2. By setting up a pull rod and a limiting mechanism, rotating the pull plate drives the pull rod and pressure plate to rotate, causing the limiting block on the outer wall of the pressure plate to move from the limiting groove to the guide groove. Then, pulling the pull plate will allow the pressure plate to slide along the guide groove and separate from the valve body. During this process, the elastic airbag ring loses pressure and rebounds, and the gas in the sealing airbag ring flows back to the elastic airbag ring. The sealing airbag ring shrinks and drives the locking block to move into the annular relief groove, thereby releasing the limiting of the valve cap and facilitating the rotation and removal of the valve cap. The operation is convenient and quick. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 An anti-aging, high-pressure resistant, all-copper vacuum tire valve for light trucks includes a valve body 1, a connector 2 at one end of the valve body 1, a valve cap 3 screwed onto the end of the valve body 1 away from the connector 2, an annular groove 4 at the end of the valve body 1 away from the connector 2, a sealing mechanism 5 disposed within the annular groove 4, and a pull rod 6 extending through the side of the valve cap 3, with a limiting mechanism 7 disposed on the pull rod 6. The annular groove 4 at the end of the valve body 1 provides an installation base for the subsequent sealing mechanism 5, increasing the sealing performance between the valve cap 3 and the valve body 1. The pull rod 6 on the side of the valve cap 3, along with the limiting mechanism 7, facilitates the disassembly and installation of the valve cap 3.

[0024] Reference Figure 2 , Figure 3 The sealing mechanism 5 includes an elastic airbag ring 51 disposed on the inner wall of the annular groove 4, an annular relief groove 52 is provided on the outer wall of the connection between the valve body 1 and the valve cap 3, and a sealing airbag ring 53 is provided on the inner wall of the annular relief groove 52. The sealing airbag ring 53 and the elastic airbag ring 51 are connected by a conduit 55. An annular sealing groove 54 adapted to the sealing airbag ring 53 is provided on the inner wall of the valve cap 3. When the valve cap 3 is tightened, the gas in the elastic airbag ring 51 is squeezed into the sealing airbag ring 53, causing it to expand and tightly embed into the annular sealing groove 54 on the inner wall of the valve cap 3, thereby achieving an extremely high sealing effect.

[0025] Reference Figure 3The inner wall of the annular sealing groove 54 is symmetrically provided with slots 56, and the outer wall of the sealing airbag ring 53 is symmetrically fixed with a locking block 57 that matches the slot 56; the use of the slot 56 and the locking block 57 further enhances the stability of the seal, and also provides an additional limiting function for the installation of the nozzle cap 3.

[0026] Reference Figure 3 Both the card block 57 and the card slot 56 have square cross-sectional shapes, which makes the movement of the card block 57 in the card slot 56 more stable.

[0027] Reference Figure 2 , Figure 4 The limiting mechanism 7 includes a pressure plate 71 fixedly installed on one end of the pull rod 6 located inside the nozzle cap 3. A spring 72 is fitted on the pull rod 6. A guide groove 73 is opened on the inner wall of the nozzle cap 3. Two limiting grooves 74 are opened on the inner wall of the nozzle cap 3, and the two limiting grooves 74 are respectively connected to the two ends of the guide groove 73. The limiting mechanism 7 is the key to ensuring that the nozzle cap 3 is stably installed and easy to disassemble, and also ensures the stability of the nozzle cap 3 during use.

[0028] Reference Figure 4 The outer wall of the pressure plate 71 is fixedly installed with a limiting block that is compatible with the guide groove 73 and the limiting groove 74. A sealing gasket is provided on the side of the pressure plate 71 opposite to the valve body 1. A sealing gasket is also provided on the side of the pressure plate 71 opposite to the valve body 1, which further improves the sealing performance.

[0029] Reference Figure 2 A pull plate 8 is fixedly installed at one end of the pull rod 6 located outside the cap 3; the pull plate 8 facilitates the operation of the pull rod 6 and ensures that the pull rod 6 and the pressure plate 71 are more convenient to use.

[0030] The specific working principle of this utility model is as follows:

[0031] In use, the valve body 1 can be installed on the car wheel hub through the connector 2, and the vacuum tire can be inflated or deflated through the valve body 1. After the operation is completed, the valve cap 3 can be screwed onto the valve body 1. During the screwing process, when the pressure plate 71 contacts the elastic airbag ring 51, continue to screw the valve cap 3. The pressure plate 71 can squeeze the elastic airbag ring 51, so that the gas in the elastic airbag ring 51 is guided to the sealing airbag ring 53 through the conduit 55. The sealing airbag ring 53 expands and can enter the annular sealing groove 54 on the inner wall of the valve cap 3. The cooperation between the sealing airbag ring 53 and the annular sealing groove 54 can make the sealing between the valve cap 3 and the valve body 1 better. When the sealing airbag ring 53 enters the annular sealing groove 54, the locking block 57 on its outer wall can be inserted into the locking groove 56 on the inner wall of the annular sealing groove 54 at the same time, further limiting the valve cap 3 and preventing the valve cap 3 from falling off during driving.

[0032] When it is necessary to unscrew the valve cap 3 from the valve body 1, the pull plate 8 can be rotated to drive the pull rod 6 and the pressure plate 71 to rotate, so that the limiting block on the outer wall of the pressure plate 71 rotates from the limiting groove 74 to the guide groove 73. Then, the pull plate 8 is pulled to make the pressure plate 71 slide along the guide groove 73 and separate from the valve body 1. At this time, the elastic airbag ring 51 can rebound after losing pressure. The gas in the sealing airbag ring 53 can be drawn back into the elastic airbag ring 51 through the conduit 55. The shrinking of the sealing airbag ring 53 can drive the locking block 57 to move into the annular relief groove 52, releasing the limiting of the valve cap 3. Then the valve cap 3 can be rotated to remove the valve body 1.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
