[0002] A valve cap is a protective device used to protect the valve core from physical damage and chemical corrosion, and it also has the function of preventing gas leakage.

[0003] In the production process of construction machinery, such as mining trucks, tires need to be inflated. Mining truck tires have high air pressure, and the valve caps are generally made of brass with a smooth surface. In addition, the wheel rims of mining trucks are deep, and the valves are located inside the wheel rims. It is not possible to stably clamp and loosen the valve caps using tools such as pliers, and it cannot be guaranteed that the valve caps can be removed every time, which affects production efficiency. Utility Model Content

[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a tire valve cap removal device, which can stably remove the valve caps of mining trucks and other construction machinery, thus ensuring production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a tire valve cap removal device, including a first clamp arm and a second clamp arm that are hinged to each other. The front end of the first clamp arm is provided with a first clamping part, and the front end of the second clamp arm is provided with a second clamping part. The first clamping part and the second clamping part are symmetrically arranged. The first clamping part includes a first clamping plate and a second clamping plate. Both the first clamping plate and the second clamping plate are arc-shaped plates, and the arc of the first clamping plate is greater than the arc of the second clamping plate.

[0006] Furthermore, a first hinge hole is provided in the middle of the first clamp arm, and a second hinge hole is provided in the middle of the second clamp arm. The axes of the first hinge hole and the second hinge hole coincide, and a rotating shaft is riveted into the first hinge hole and the second hinge hole.

[0007] Furthermore, a first handle is provided at the rear end of the first clamp arm, and a second handle is provided at the rear end of the second clamp arm. The first handle and the second handle have the same structure and are arranged symmetrically.

[0008] Furthermore, both the first and second handles are provided with gripping parts, which are formed by bending the clamp arms outward.

[0009] Furthermore, the height of the first clamping plate is the same as the height of the second clamping plate.

[0010] Furthermore, the top of one end face of the first clamping plate is connected to the top of one end face of the second clamping plate.

[0011] Furthermore, the end of the second clamping plate away from the first clamping plate is connected to the end of the first clamping arm.

[0012] Furthermore, reinforcing plates are provided on both sides of the first clamping plate near the end of the second clamping plate.

[0013] Furthermore, one side of the reinforcing plate is fixedly connected to the end face of the first clamping plate, and the other side is fixedly connected to the side wall of the second clamping plate.

[0014] Furthermore, the inner surfaces of the first clamping plate and the second clamping plate are provided with a plurality of protrusions, which are evenly arranged.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a first clamping plate and a second clamping plate at the front end of the first clamping arm and the second clamping arm. Both the first clamping plate and the second clamping plate are arc-shaped plates, which can be adapted to the shape of the valve cap, thereby achieving stable clamping of the valve cap. At the same time, by providing multiple protrusions on the inner side of the first clamping plate and the second clamping plate, the friction between them and the valve cap can be increased, making it easier to loosen the valve cap.

[0016] 2. By setting a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate have different curvatures, this utility model can clamp valve caps of different sizes, thereby improving the applicability of the removal device.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] A typical embodiment of this utility model is as follows: Figure 1As shown, a tire valve removal device includes a first clamping arm 1 and a second clamping arm 2, which are arranged crosswise. The first clamping arm 1 has a first hinge hole in the middle, and the second clamping arm 2 has a second hinge hole in the middle. The axes of the first hinge hole and the second hinge hole coincide. A rotating shaft 3 is riveted into the first hinge hole and the second hinge hole to achieve a rotational connection between the first clamping arm 1 and the second clamping arm 2.

[0020] The first clamp arm 1 has a first handle 4 at its rear end, and the second clamp arm 2 has a second handle 5 at its rear end. The first handle 4 and the second handle 5 have the same structure and are symmetrically arranged. Both the first handle 4 and the second handle 5 are provided with a gripping part, which is formed by bending the clamp arm outward, so that the gripping parts on the first handle 4 and the second handle 5 form a symmetrical arc structure, which is convenient for the operator to hold.

[0021] The first clamp arm 1 has a first clamping part 6 at its front end, and the second clamp arm 2 has a second clamping part 7 at its front end. The first clamping part 6 and the second clamping part 7 are symmetrically arranged. Under the drive of the first handle 4 and the second handle 5, the first clamping part 6 and the second clamping part 7 can open and close relative to each other, thereby clamping the valve cap.

[0022] The first clamping part 6 and the second clamping part 7 have the same structure, so only the first clamping part 6 will be described here.

[0023] like Figure 2 As shown, the first clamping part 6 includes a first clamping plate 61 and a second clamping plate 62. Both the first clamping plate 61 and the second clamping plate 62 are arc-shaped plates. The curvature of the first clamping plate 61 is greater than that of the second clamping plate 62, and the height of the first clamping plate 61 and the height of the second clamping plate 62 are the same. In this embodiment, the end face of the first clamping plate 61 is an arc-shaped structure with a length of 5mm, a height of 5mm, and a radius of 8mm, and the end face of the second clamping plate 62 is an arc-shaped structure with a length of 10mm, a height of 5mm, and a radius of 6mm.

[0024] like Figure 3 As shown, the top of one end face of the first clamping plate 61 is connected to the top of one end face of the second clamping plate 62, and the end of the second clamping plate 62 away from the first clamping plate 61 is connected to the end of the first clamping arm 1, so that the first clamping arm 1 can drive the first clamping plate 61 and the second clamping plate 62 to rotate around the hinge point.

[0025] Reinforcing plates 63 are provided on both sides of the first clamping plate 61 near the end of the second clamping plate 62. One side of the reinforcing plate 63 is fixedly connected to the end face of the first clamping plate 61, and the other side is fixedly connected to the side wall of the second clamping plate 62. By providing reinforcing plates 63 between the first clamping plate 61 and the second clamping plate 62, the connection strength between the first clamping plate 61 and the second clamping plate 62 is improved.

[0026] Multiple protrusions 64 are provided on the inner sides of the first clamping plate 61 and the second clamping plate 62. The multiple protrusions 64 are evenly arranged, thereby increasing the friction between the first clamping plate 61 and the second clamping plate 62 and the valve cap when clamping the valve cap, making it easier to loosen the valve cap.

[0027] In use, the valve cap is clamped by the first clamping plate 61 and the second clamping plate 62 on the first clamping part 6 and the second clamping part 7. Since the first clamping plate 61 and the second clamping plate 62 are both arc-shaped and adapted to the shape of the valve cap, the contact area with the valve cap can be increased, thereby ensuring the stability of clamping the valve cap. By using the different curvatures of the first clamping plate 61 and the second clamping plate 62, valve caps of different sizes can be clamped, improving the applicability of the removal device.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
