Description

Technical Field

[0001] This utility model relates to the field of tire disassembly technology, and in particular to a tire disassembly tool. Background Technology

[0002] Replacing, repairing, and removing tires are common maintenance tasks in our daily work. While pneumatic impact wrenches are now used to remove tire lug nuts, saving considerable effort, removing the tire from the axle still requires manual labor. A tire set weighs approximately 100 kilograms, and removing it by one person is quite difficult; sometimes, two people are needed. Removing the tire also requires certain skills; the tire must be perpendicular to the axle for successful removal. Tire removal is a laborious and costly process. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a tire removal tool.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A tire removal tool includes a main body, a clamping shaft at one end of the main body, an angle between the clamping shaft and the main body, a fastener on one side of the main body, the fastener and the clamping shaft being located at the same end of the main body, a movable shaft connected to the fastener via a pin, the movable shaft rotating around the pin, and a protrusion at the end of the movable shaft.

[0006] By adopting the above technical solution, after removing the outer tire, taking the protrusion engaging the heat dissipation hole below the steel rim as an example, the protrusion (equivalent to a hook) on the movable shaft is used to engage the heat dissipation hole inside the steel rim. The front end of the clamping shaft is used to press against the shaft head, and the operator holds the tire. Then, using the lever principle, the tire is lifted upwards, that is, the main body is lifted towards the end closer to the clamping shaft. The upper end of the tire will loosen, and the tire can be removed under continuous lifting. Once the tire is loose, it can be removed. Similarly, when it is necessary to remove the inner tire, the same method can be used to remove the inner tire. Taking the protrusion engaging the heat dissipation hole above the steel rim as another example, the protrusion is used to engage the heat dissipation hole of the steel rim. A support point is selected on the shaft head, and the main body is pressed down, that is, the main body is pressed down towards the side closer to the clamping shaft. Using the lever principle, the tire can be pulled out, achieving the purpose of easily removing the tire. This tool not only saves the physical strength and repair time of maintenance personnel, but also greatly improves the safety of operation. Compared with the previous method of two people working together to remove tires, it is both labor-saving and effortless.

[0007] Furthermore, the clamping shaft is integrally formed with the main body.

[0008] Furthermore, a clamping block is provided at the end of the clamping shaft away from the main body, and the width of the clamping block is greater than the diameter of the clamping shaft.

[0009] By adopting the above technical solution, the width of the clamping block is greater than the diameter of the clamping shaft. When it presses against the shaft head, the clamping block can increase the contact area between the clamping shaft and the shaft head, thereby improving the stability during clamping.

[0010] Furthermore, the included angle between the clamping shaft and the main body is 90° to 180°.

[0011] Furthermore, the fastener includes a fastening block, the fastening block being U-shaped, the pin passing through the movable shaft and the fastening block, and the pin being rotatably connected to the movable shaft and the fastening block.

[0012] Furthermore, the fastener also includes a fastening shaft and a fixing sleeve, the fixing sleeve being welded to the main body, and the fastening shaft passing through the fixing sleeve and rotating within the fixing sleeve.

[0013] Furthermore, the end of the main body away from the clamping shaft is provided with an anti-slip sleeve, which serves to protect the operator's hands and also provides an anti-slip function.

[0014] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0015] (1) After removing the outer tire, take the protrusion that holds the heat dissipation hole below the steel rim as an example. Hold the protrusion (which is equivalent to a hook) on the movable shaft downwards to hold the heat dissipation hole inside the steel rim. Use the front end of the clamping shaft to press against the shaft head. The operator holds the tire and then uses the lever principle to lift it upwards, that is, lift the main body towards the end closer to the clamping shaft. The upper end of the tire will loosen and the tire will be removed under continuous lifting. Once the tire is loose, it can be removed. Similarly, when it is necessary to remove the inner tire, the same method can be used to remove the inner tire. Take the protrusion that holds the heat dissipation hole above the steel rim as another example. Hold the protrusion to hold the heat dissipation hole of the steel rim. Select a support point on the shaft head and press the main body, that is, press the main body down towards the side closer to the clamping shaft. Using the lever principle, the tire can be pulled out, achieving the purpose of easily removing the tire. This tool not only saves the physical strength and maintenance time of the maintenance personnel, but also greatly improves the safety of operation. Compared with the previous two people working together to remove the tire, it is both labor-saving and effortless.

[0016] (2) The width of the clamping block is greater than the diameter of the clamping shaft. When it presses against the shaft head, the clamping block can increase the contact area between the clamping shaft and the shaft head, and improve the stability during clamping.
