Description

Technical Field

[0001] The utility model relates to the technical field of wheel side valves, and more specifically, to a wheel side valve assembly. Background Art

[0002] The central inflation and deflation system of the tires of a small car consists of a compressed air gas source, a control air circuit, a rotary sealing air chamber, a wheel side valve, and corresponding pipelines to form a complete system for adjusting the air pressure of the tires to meet the different requirements of different road surfaces for the air pressure of the vehicle tires. Among them, the wheel side valve is an important component in the central tire deflation system.

[0003] Usually, a wheel side valve is installed on the wheel during the automobile production process to protect the inflation and deflation of the automobile tires. However, during the use of the common wheel side valve, due to the internal sealing structure, it will be resisted by the internal air pressure of the vehicle tire during the inflation process, resulting in difficult inflation, reducing the inflation efficiency. And during the use of the vehicle, the air inside the vehicle tire may leak due to the extrusion of the vehicle tire, reducing the safety of using the wheel side valve. Therefore, we have designed a wheel side valve assembly to solve the above problems. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a wheel side valve assembly. The wheel side valve assembly can quickly fix the check valve at one end of the air passage through the set limit groove and positioning screw, thereby preventing air from flowing back, greatly improving the inflation and intake efficiency of the vehicle tire. And through the set plug and the sealing block arranged at one end of the plug, the communication hole can be blocked by elasticity, avoiding the air leakage in the vehicle tire, and at the same time not affecting the inflation of the vehicle tire, greatly improving the safety of using the wheel side valve.

Embodiment

[0024] Please refer to Figures 1-5 , a wheel-end valve assembly, including a total cost body 1, an air intake head 2, an adjusting rod 3 and an air outlet joint 5 are fixedly installed on the surface of the total cost body 1. There is an air core inside the air intake head 2, and one end of the air core abuts against one end of the adjusting rod 3 to control the sealing and rapid exhaust of the air core, which belongs to the prior art. One end of the air outlet joint 5 is threadedly connected to an air outlet head 4. One end of the air intake head 2 is provided with an air intake hole 21, and one end of the air outlet head 4 is provided with an air outlet hole 41. One end of the air intake hole 21 is communicated with an air passage 11, and one end of the air passage 11 is communicated with a limiting groove 12. A check valve 6 is in contact connection with the inner wall of the limiting groove 12. A positioning screw 61 is in contact and extrusion with the surface of the check valve 6. One end of the limiting groove 12 is communicated with a piston groove 13. A clamping hole is provided on the inner wall of the piston groove 13, and the inner wall of the clamping hole is in contact and extrusion with one end of a spring 72, which can quickly limit one end of the spring 72. A piston 7 is slidably connected in the piston groove 13. One end of the piston 7 is clamped with a spring 72. The connection method and working principle of the piston 7 and the spring 72 belong to the prior art and are well known to those skilled in the art, so no detailed description will be given here. A communication hole 71 is provided at the central position of the piston 7. One end of the piston groove 13 is communicated with a plug groove 14. A plug 8 is threadedly connected to the inner wall of the plug groove 14. One end of the plug 8 is provided with a card slot 83, and an opening 85 is provided on one side of the card slot 83. After the sealing block 84 is deformed, the opening 85 is convenient for the inflation gas to enter the plug groove 14 through the air intake hole 21 and then enter the air outlet hole 41. A sealing block 84 is clamped in the card slot 83. A positioning plate 9 is detachably connected to the surface of the total cost body 1, and the inner surface of the positioning plate 9 is in contact and extrusion with the surface of the air outlet joint 5.

[0025] Threaded holes are provided on the surface of the total cost body 1, and one end of the threaded holes is communicated with the limiting groove 12. The surface of the positioning screw 61 is threadedly connected to the inner wall of the threaded holes. An extrusion plane is provided on the surface of the check valve 6. The check valve 6 can prevent the gas filled into the air intake hole 21 from flowing back, improving the inflation efficiency. A positioning hole 91 is provided on the surface of the positioning plate 9, and threaded holes concentric and coaxial with the positioning hole 91 are provided on the surface of the total cost body 1. A positioning screw 92 is threadedly connected to the inner wall of the threaded holes. The positioning plate 9 is convenient for the quick positioning of the air outlet joint 5 and is also convenient for later disassembly and maintenance.

[0026] The plugging block 84 is made of elastic sealing rubber. A hollow groove 86 is arranged inside the plugging block 84. The center of the hollow groove 86 and the axis of the communication hole 71 are on the same axis. The hollow groove 86 can reduce the support strength at the center position of the plugging block 84 when the communication hole 71 inflates the plugging block 84, which is convenient for improving the inflation efficiency. The side of the plug 8 is detachably connected with a limit plate 81 through a fastening screw 82. Sealing rings are arranged on the surfaces of the limit plate 81 and the positioning screw 61, ensuring the sealing performance of the connection part.

[0027] When the wheel side valve assembly is in use, the inflation gas enters the air passage 11 through the air inlet hole 21, and then enters the piston groove 13 through the check valve 6. The gas in the piston groove 13 cannot flow back into the air inlet hole 21 through the check valve 6. The air entering the piston groove 13 blows on the surface of the plugging block 84 through the communication hole 71. At the same time, the inlet gas squeezes the plugging block 84 to deform it, so that a gap is generated between the gas outlet end of the communication hole 71 and the plugging block 84, allowing the gas to enter the plug groove 14, and then enter the air outlet hole 41. Then the gas enters the vehicle tire through the air outlet hole 41 for inflation. When not inflating, the gas in the vehicle tire enters the plug groove 14 through the air outlet hole 41, and at the same time the gas contacts the surface of the plugging block 84 through the opening 85. At this time, the position where the gas contacts the plugging block 84 is not within the range of the hollow groove 86, so that the gas cannot squeeze the plugging block 84 to deform and generate a gap. By setting the limit groove 12 and the positioning screw 61, the check valve 6 can be quickly fixed at one end of the air passage 11, thus preventing air from flowing back, greatly improving the inflation and air intake efficiency of the vehicle tire. And by setting the plug 8 and the plugging block 84 arranged at one end of the plug 8, the communication hole 71 can be blocked by elasticity, avoiding air leakage in the vehicle tire, and at the same time not affecting the inflation of the vehicle tire, greatly improving the use safety of the wheel side valve.
