Description

Technical Field

[0001] The utility model relates to the technical field of air valves, in particular to a copper alloy air valve. Background Art

[0002] The function of the valve is to inflate and deflate the tire, and to maintain the seal of the tire after inflation. The valve is an indispensable and important part of the engine. The valve is responsible for controlling the air in and out of the cylinder, and has an important impact on the engine's performance and emissions. Reasonable selection and use of relevant valves can effectively improve the engine's output power and torque, reduce energy waste and environmental pollution. Most valves are made of copper alloys. This alloy has high hardness and strength, which enhances its wear resistance and corrosion resistance, thereby ensuring the reliability and durability of the tire valve.

[0003] The specific structure of the existing valve includes a valve base, a valve core, and a valve cap. The valve is installed on the tire through the valve base. The valve core is located in the valve to ensure the sealing of gas or liquid. The valve cap is screwed on the valve to prevent dust and impurities from falling.

[0004] Since the fixing method of the valve cap is simple, the valve cap may fall off during the rolling of the tire, causing the valve core to lose its protection, making it easier for dust and impurities to contact the valve core, thereby reducing the service life of the valve.

[0005] Based on this, the utility model designs a copper alloy valve to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a copper alloy valve to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a limiting block is arranged on the valve cap, a sliding block is arranged on the limiting block, a sliding groove is arranged on the valve cap, the sliding block slides in the sliding groove, an anti-dropping block is fixedly arranged on the valve base, an anti-dropping groove is opened on the anti-dropping block, and when the bottom of the valve cap contacts the anti-dropping block, the limiting block is inserted into the anti-dropping groove.

[0008] By adopting the above technical solution, when the valve cap is screwed on the valve base, the valve cap is pressed against the fixed block and the sliding limit block. When the slider slides to the bottom of the slide groove, the limit block slides into the anti-detachment groove. At this time, the valve cap is limited and cannot rotate. During the rotation of the tire, the valve cap will not easily separate from the valve base due to vibration or other external forces, thereby strengthening the connection between the valve cap and the valve base, and effectively extending the service life of the valve core.

[0009] Preferably, a receiving groove is provided on the limit block, an elastic rope is provided in the receiving groove, a positioning block is fixedly provided on the valve cap, and when the sliding block slides to the top of the sliding groove, the elastic rope is sleeved on the positioning block.

[0010] By adopting the above technical solution, when removing the valve cap, slide the limit block upwards until the slider slides to the top of the slide groove, then pull the elastic rope out of the accommodating groove, rotate the elastic rope to make it tightly wrap around the positioning block, so that the limit block is fixed on the valve cap and no longer slides. At this time, the valve cap can be rotated to remove it from the valve base, which is convenient for the user to rotate the valve cap.

[0011] Preferably, a limiting layer is provided in the anti-slip groove, and when the limiting block is located in the anti-slip groove, the limiting layer is tightly pressed against the limiting block.

[0012] By adopting the above technical solution, when the limiting block is inserted into the anti-detachment groove, the limiting layer can be pressed tightly against the limiting block, thereby further preventing the limiting block from detaching and enhancing the stability of the valve cap.

[0013] Preferably, a sealing strip is provided at the bottom of the valve cap.

[0014] By adopting the above technical solution, after the valve cap is tightened, the sealing strip at the bottom thereof is tightly pressed against the fixing block, thereby preventing dust and impurities from entering the valve cap through the gap, thereby improving the sealing performance of the valve cap.

[0015] Preferably, a toggle block is provided on the limit block.

[0016] By adopting the above technical solution, when the sliding block is slid, the toggle block can better help slide and identify the sliding block, making the sliding of the sliding block easier and smoother.

[0017] To sum up, the present application has the following beneficial technical effects: when the valve cap is screwed on the valve base, the valve cap is pressed against the fixed block and the sliding limit block. When the slider slides to the bottom of the slide groove, the limit block slides into the anti-detachment groove. At this time, the valve cap is limited and cannot rotate. During the rotation of the tire, the valve cap will not easily detach from the valve base due to vibration or other external forces, thereby strengthening the connection between the valve cap and the valve base, effectively extending the service life of the valve core.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figures 1-4 This application is described in further detail.

[0027] A copper alloy air valve comprises an air valve base 1, a valve core arranged in the air valve and a air valve cap 3 screwed on the air valve base 1, the top of the air valve base 1 is provided with an external thread, the inner side of the air valve cap 3 is provided with an internal thread, a limiting block 4 is provided on the air valve cap 3, a sliding block 44 is provided on the limiting block 4, a sliding groove 32 is provided on the air valve cap 3, the sliding block 44 slides in the sliding groove 32, an anti-slip block 2 is fixedly provided on the air valve base 1, an anti-slip block 2 is provided with an anti-slip groove 21, a limiting layer 211 is provided in the anti-slip groove 21, a toggle block 41 is provided on the limiting block 4, and a sealing strip 22 is provided at the bottom of the air valve cap 3.

[0028] When in use, cover the valve cap 3 on the top of the valve base 1, and by rotating, the internal thread and the external thread are meshed, and the valve cap 3 is screwed on the valve base 1, and the valve cap 3 is rotated downward until the sealing strip 22 at the bottom of the valve cap 3 is pressed against the fixing block, and the limit block 4 on the valve is aligned with the anti-slip groove 21 on the fixing block. At this time, press the toggle block 41 to move the limit block 4 downward, and the slider 44 on the limit block 4 moves in the slide groove 32. When the slider 4 When the stopper 4 moves to the bottom of the slide groove 32, the limit block 4 is inserted into the lower anti-slip groove 21, and the limit layer 211 in the anti-slip groove 21 presses the limit block 4 tightly, so that the limit block 4 is limited in the anti-slip groove 21 and no longer moves, and the valve cap 3 cannot rotate. When affected by external force, the valve cap 3 will not easily separate from the valve base 1, thereby strengthening the connection between the valve cap 3 and the valve base 1, preventing other impurities from entering the valve and affecting the use and life of the valve.

[0029] The limit block 4 is provided with a receiving groove 42, and an elastic rope 43 is provided in the receiving groove 42. A positioning block 31 is fixedly provided on the top of the valve cap 3. When the valve cap 3 is disassembled, the toggle block 41 is first pushed upward to make the limit block 4 slide upward, and the slider 44 on the limit block 4 slides upward in the slide groove 32. When the slider 44 slides to the top of the slide groove 32, the limit block 4 is completely separated from the anti-slip groove 21. At this time, the elastic rope 43 can be pulled out of the receiving groove 42, and then the elastic rope 43 is rotated, and the elastic rope 43 is sleeved on the positioning block 31 for fixing. The elastic rope 43 tightens the limit block 4 so that it no longer slides downward. After the limit block 4 is fixed, the valve cap 3 can be rotated to unscrew it from the valve base 1, so as to avoid the inconvenience caused by the valve cap 3 sliding downward during the disassembly process.

[0030] When the limit block 4 on the valve cap 3 is slid, the toggle block 41 can allow the user to identify the specific position of the limit block 4 by touch at the first time, and it can also save more effort, facilitate the connection between the limit block 4 and the anti-slip block 2, and improve the assembly efficiency of the valve cap 3; the limit layer 211 is distributed on the inner wall of the anti-slip groove 21. After the limit block 4 enters the anti-slip groove 21, the limit layer 211 and the limit block 4 are squeezed, further limiting the limit block 4, making it less likely to slide out of the anti-slip groove 21; the sealing strip 22 at the bottom of the valve cap 3 can further increase the sealing of the valve cap 3, prevent dust and impurities from entering the valve through the gap and corroding the valve core, thereby extending the service life of the valve.

[0031] The implementation principle of this embodiment is as follows: when in use, the valve cap 3 is covered on the top of the valve base 1, and the internal thread and the external thread are engaged by rotation, and the valve cap 3 is screwed onto the valve base 1, and the valve cap 3 is rotated downward until the sealing strip 22 at the bottom of the valve cap 3 is pressed against the fixed block, and the limit block 4 on the valve is aligned with the anti-slip groove 21 on the fixed block. At this time, the toggle block 41 is pressed to move the limit block 4 downward, and the slider 44 on the limit block 4 moves in the slide groove 32 When the slider 44 moves to the bottom of the slide groove 32, the limit block 4 is inserted into the anti-slip groove 21, and the limit layer 211 in the anti-slip groove 21 presses the limit block 4 tightly. The limit block 4 is limited in the anti-slip groove 21 and no longer moves. The valve cap 3 cannot rotate. When affected by external force, the valve cap 3 will not easily detach from the valve base 1, which strengthens the connection between the valve cap 3 and the valve base 1 and prevents other impurities from entering the valve and affecting the use and life of the valve.

[0032] When the valve cap 3 is disassembled, the toggle block 41 is first pushed upward to make the limit block 4 slide upward, and the slider 44 on the limit block 4 slides upward in the slide groove 32. When the slider 44 slides to the top of the slide groove 32, the limit block 4 is completely disengaged from the anti-slip groove 21. At this time, the elastic rope 43 can be pulled out of the accommodating groove 42, and then the elastic rope 43 is rotated and the elastic rope 43 is sleeved on the positioning block 31 for fixing. The elastic rope 43 tightens the limit block 4 so that it no longer slides downward. After the limit block 4 is fixed, the valve cap 3 can be rotated to remove it from the valve base 1, thereby avoiding the inconvenience caused by the valve cap 3 sliding downward during the disassembly process.
