Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air valve, especially to an air valve with replaceable valve core. BACKGROUND

[0002] The air valve is a device installed on a tire or an inner tube for inflating, deflating and maintaining the air pressure of the tire. The valve core is the core component of the air valve, which controls the inflow and outflow of air to ensure the stable air pressure of the tire after inflation.

[0003] In the prior art, the connection between the valve core and the air valve is mainly achieved by screwing or clamping. The clamping connection is achieved by matching the clamping piece on the valve core with the corresponding clamping groove or clamping hole of the air valve to fix the two. However, this connection method has obvious defects. In the clamping connection, the clamping piece that plays a connecting role is usually relatively fragile and prone to breakage under the influence of external force impact, frequent opening and closing, or material aging. Since the clamping piece is directly connected with the air valve, once it breaks, the air valve can no longer be installed with the valve core, making the entire air valve lose its function and unable to perform normal inflation and deflation operations, which seriously affects the use of the tire. The user can only replace the new air valve, causing unnecessary economic loss. SUMMARY

[0004] The utility model aims at solving the defects in the prior art and provides an air valve with replaceable valve core.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] An air valve with replaceable valve core, comprising a rod body and a valve core, the rod body is provided with a mounting groove, the valve core is installed in the mounting groove, the valve core is provided with a mounting ring, the mounting ring is provided with a movable slot, the movable slot is provided with a pressing plate through a pressing mechanism, the movable slot is provided with a dismounting plate through a mounting mechanism, and the dismounting plate is connected with the rod body through a positioning mechanism.

[0007] Preferably, the pressing mechanism comprises a pressing spring arranged in the movable slot, and the two ends of the pressing spring are connected with the outer wall of the pressing plate and the inner wall of the movable slot respectively.

[0008] Preferably, the mounting mechanism comprises a mounting block mounted on the dismounting plate, and the mounting ring is provided with a mounting hole corresponding to the mounting block and communicating with the movable slot.

[0009] Preferably, the positioning mechanism comprises a positioning block mounted on the dismounting plate, and the rod body is provided with a positioning hole corresponding to the positioning block and communicating with the mounting groove.

[0010] Preferably, the rod body is provided with a rectangular groove, which corresponds to the positioning hole.

[0011] Preferably, the mounting ring is welded onto the valve core, and both the positioning block and the mounting block are welded onto the disassembly plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. With the help of the compression spring in the compression mechanism, the compression plate can easily compress and loosen the mounting plate. When replacing the valve core, the positioning block can be disengaged from the positioning hole by simply overcoming the elasticity of the compression spring, thereby quickly removing the mounting plate. The whole process does not require complicated tools, is easy to operate, greatly shortens the valve core replacement time, and improves work efficiency.

[0014] 2. When components that serve a fixing function, such as the mounting plate, mounting block, or positioning block, are damaged, their unique installation structure allows for easy removal of the damaged component from the valve stem by simply reversing the squeezing mechanism to disengage the mounting block from the mounting hole. This enables timely replacement of the damaged component and avoids rendering the entire valve stem unusable due to damage to a single component, thus reducing maintenance and time costs.

[0015] 3. Under normal operating conditions, the mounting plate is firmly fixed to the valve stem by the action of the pressing plate and the tight fit between the mounting block and the mounting hole, and the positioning block and the positioning hole. This ensures that the valve stem can operate stably under various operating conditions, effectively preventing problems such as valve core loosening and gas leakage, and improving the reliability and safety of the valve stem.

[0024] The rod body 1 is provided with a mounting groove 2, the valve core 3 is mounted in the mounting groove 2, the valve core 3 is provided with a mounting ring 4, the mounting ring 4 is provided with a movable groove 9, the movable groove 9 is provided with a squeezing plate 10 through a squeezing mechanism, the movable groove 9 is provided with a dismounting plate 7 through a mounting mechanism, and the dismounting plate 7 is connected with the rod body 1 through a positioning mechanism.

[0025] The squeezing mechanism comprises a squeezing spring 11 arranged in the movable groove 9, and the two ends of the squeezing spring 11 are connected with the outer wall of the squeezing plate 10 and the inner wall of the movable groove 9 respectively. The elastic potential energy provided by the squeezing spring 11 realizes the squeezing of the squeezing plate 10, so that the squeezing of the dismounting plate 7 is realized by means of the squeezing plate 10.

[0026] The mounting mechanism comprises a mounting block 13 mounted on the dismounting plate 7, and the mounting ring 4 is provided with a mounting hole 12 corresponding to the mounting block 13 and communicating with the movable groove 9. When the dismounting plate 7 is squeezed, the mounting block 13 can be squeezed into the mounting hole 12, and at this time, the dismounting plate 7 cannot be separated from the movable groove 9.

[0027] The positioning mechanism comprises a positioning block 8 mounted on the dismounting plate 7, and the rod body 1 is provided with a positioning hole 6 corresponding to the positioning block 8 and communicating with the mounting groove 2. When the dismounting plate 7 is squeezed, the positioning block 8 can be squeezed into the positioning hole 6.

[0028] The rod body 1 is provided with a rectangular groove 5 corresponding to the positioning hole 6. The rectangular groove 5 facilitates the user to clamp the rod body 1 with a tool, so as to facilitate the installation of the rod body 1. The positioning hole 6 is arranged at the position of the rectangular groove 5, so that the subsequent dismounting device can enter the positioning hole 6, so that the positioning block 8 is squeezed to be separated from the positioning hole 6.

[0029] The mounting ring 4 is welded and mounted on the valve core 3, and the positioning block 8 and the mounting block 13 are both welded and mounted on the dismounting plate 7. The welding installation guarantees the stability of the installation between the multiple components.

[0031] When the valve core 3 needs to be disassembled, the positioning block 8 in the positioning hole 6 is pressed, the positioning block 8 drives the dismounting plate 7 to move and thus pushes the extrusion plate 10 to move, and then the extrusion spring 11 is compressed, and since the dismounting plate 7 moves, the installation block 13 also separates from the installation hole 12, at this time, the valve core 3 can be conveniently separated from the rod body 1 and disassembled, and the dismounting plate 7 can also be conveniently separated from the valve core 3 and disassembled.

[0032] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme and the utility model concept of the utility model, carries out equivalent replacement or change, and all should be covered in the protection scope of the utility model.
