[0002] In the automotive repair industry, tire change hooks (tire change hooks) are key components of tire changers, and their performance directly affects the efficiency of tire removal and installation, as well as the tire's lifespan. Traditional tire change hooks are mostly made of metal. While this material provides sufficient strength, it has certain limitations in practical use. Specifically, during tire removal and installation, metal tire change hooks make rigid contact with the tire bead and rim. This contact method can easily cause mechanical damage to the tire bead and deformation of the rim, thus creating potential problems for subsequent tire assembly.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] This embodiment provides an automatic hook assembly / disassembly structure, such as... Figures 1 to 4 As shown, it includes: a disassembly hook 1 and a disassembly hook driving structure, wherein the disassembly hook driving structure enables the disassembly hook 1 to change its angle; The disassembly hook 1 is made of plastic and is detachably connected to the disassembly hook drive structure. The plastic is preferably nylon PA6 or high molecular weight polyethylene.

[0018] This embodiment provides an automatic tire removal and installation hook structure. The removal and installation hook 1 is driven by a hook drive structure to perform tire removal and installation operations. The removal and installation hook 1 is made of plastic. When it contacts the rim or tire bead, the elasticity of the plastic effectively reduces the impact of rigid contact on the tire, avoiding mechanical damage to the tire bead and deformation of the rim. Furthermore, considering that the plastic removal and installation hook 1 is more easily damaged, it is designed to be detachably connected to the hook drive structure.

[0019] Specifically, such as Figures 1 to 4 As shown, the disassembly hook drive structure includes a disassembly hook mounting block 2, such as... Figure 7 As shown, the mounting block 2 for disassembly and assembly is provided with a slot 21, such as... Figure 5 and Figure 6 As shown, the disassembly hook 1 is provided with an insertion part 11, which can be inserted into the slot 21.

[0020] Specifically, such as Figure 7 As shown, the mounting block 2 for disassembly and assembly is provided with a limiting bolt hole 22, such as... Figure 5 and Figure 6 As shown, the limiting bolt hole 22 is provided with a limiting bolt 9 for preventing the disassembly hook 1 from disengaging from the slot 21; Unscrew the limit bolt 9 to slide the disassembly hook 1 out of the slot 21 for replacement. After replacement, tighten the limit bolt 9 to prevent the disassembly hook 1 from disengaging from the slot 21.

[0021] Specifically, such as Figure 5 and Figure 6 As shown, one end of the insertion part 11 is provided with a positioning part 12, such as... Figure 7 As shown, the mounting block 2 for disassembly and assembly is provided with a positioning surface 23 that can abut against the positioning part 12. The mounting hook 1 inserted from the slot 21 is restricted by the positioning part 12 to the depth of the insertion part 11 into the slot 21, so as to ensure the relative position of the mounting hook 1 and the mounting block 2 for disassembly and assembly.

[0022] Preferably, such as Figure 5 and Figure 6 As shown, the insertion part 11 is provided with a structural hole 13. The structural hole 13 reduces the contact area between the insertion part 11 and the slot 21, making the sliding smoother and easier to disassemble and assemble.

[0023] Specifically, such as Figure 2 and Figure 3 As shown, the disassembly hook drive structure also includes a cylinder 3, a support sleeve 4, a transmission rod 5, and a telescopic rod 6; The cylinder body of the cylinder 3 is fixed to the top of the support sleeve 4 by bolts. The piston rod of the cylinder 3 is placed inside the support sleeve 4 and is hinged to one end of the transmission rod 5 by a hinge shaft. The other end of the transmission rod 5 is hinged to the top of the disassembly hook mounting block 2 by a hinge shaft. One end of the telescopic rod 6 is rotatably connected to the outside of the support sleeve 4 via a rotating shaft, and the other end of the telescopic rod 6 is rotatably connected to the side of the disassembly hook mounting block 2 via a rotating shaft; like Figure 2 and Figure 3 As shown, the piston rod of cylinder 3 extends and retracts, driving the transmission rod 5 to move. The mounting block 2 of the tire removal hook rotates under the drive of the transmission rod 5 and the constraint of the telescopic rod 6, causing the tire removal hook 1 to change angle for tire removal operation (after inserting the tire removal hook 1 between the tire and the rim, the angle is adjusted so that the tire removal hook 1 can hook the tire bead, thus facilitating upward lifting. This is a routine operation and will not be described in detail). In addition to being able to perform tire removal operations, the tire removal hook 1 can also assist in tire installation operations because the plastic material is not easy to damage the tire. Specifically, the bottom of the tire removal hook 1 can be placed on the tire and pressed down, and the tire pressure wheel can be used to press down to install the tire onto the rim. Specifically, such as Figure 4 , Figure 8 and Figure 9 As shown, the transmission rod 5 is provided with a mating surface 51, the support sleeve 4 is provided with an adjusting bolt hole 7, and an adjusting bolt is provided in the adjusting bolt hole 7. The adjusting bolt can abut against the mating surface 51 to prevent the transmission rod 5 from shaking. During the extension and retraction of the piston rod of cylinder 3, which drives the transmission rod 5 to move, there is a state in which the mating surface 51 of the transmission rod 5 slides along the inner wall of the support sleeve 4 (taking the extension of the piston rod of cylinder 3 as an example, during the process of the transmission rod 5 extending out of the support sleeve 4, the mating surface 51 needs to slide along the inner wall of the support sleeve 4 first, and then the disassembly and assembly hook mounting block 2 constrained by the telescopic rod 6 drives the transmission rod 5 to rotate, and the transmission rod 5 avoids the support sleeve 4 through the inclined surface above the mating surface 51 to achieve angle change). However, due to limitations in machining and assembly precision, a large gap can easily form between the mating surface 51 and the support sleeve 4, which can lead to the transmission rod 5 wobbling. By setting an adjusting bolt, the end of the adjusting bolt can replace the inner wall of the support sleeve 4 to support the mating surface 51, thereby preventing wobbling. Specifically, such as Figures 1 to 3 As shown, it also includes a square bar 8, which is vertically welded and fixed to the support sleeve 4, and is slidably mounted on the tire changer via the square bar 8 (existing technology, not described in detail).

[0024] Specifically, such as Figure 8 and Figure 9As shown, the transmission rod 5 is provided with a limiting part 52, which can abut against the disassembly hook mounting block 2 to constrain the rotation angle of the disassembly hook mounting block 2.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
