[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, a wheel hub fixing chuck for tire installation and removal includes a fixing base 1, a connecting rod 2, a fixing part 3, a mounting base plate 31, a suction cup 32, a hook 34, an insertion groove 21, and a limiting groove 22. The bottom of the fixing base 1 is connected to the connecting rod 2. The fixing base 1 is made of metal to prevent breakage during tire removal. The connecting rod 2 and the bottom of the fixing base 1 are welded together or detachably connected by bolts. The fixing part 3, as shown... Figure 2 and Figure 4 As shown, the connecting rod 2 is detachably connected to the fixing part 3, which includes a mounting base plate 31 at the bottom of the connecting rod 2. The mounting base plate 31 has a circular design when viewed from above. It should be noted that the mounting base plate 31 has a through groove with a diameter larger than that of the connecting rod 2. Several suction cups 32 are connected to the bottom of the mounting base plate 31. The suction cups 32 are connected to the bottom of the mounting base plate 31 by heat fusion. The suction cups 32 are made of rubber for adsorption. The rubber material can provide initial positioning during installation, reducing the difficulty of installation. On the other hand, it can separate the bottom of the fixing base 1 from the disassembly device, reducing the noise of the bottom of the connecting rod 2 and the disassembly device when the fixing base 1 is in use.

[0027] The suction cups 32 are arranged in a 360° circular array at the bottom of the mounting base plate 31. The suction cups 32 are equipped with four limiting hooks, which are evenly distributed at the bottom of the connecting rod 2 to reduce the phenomenon of tilting at the bottom of the connecting rod 2. In addition, all the air inside the suction cups 32 will be discharged during use, further reducing the probability of tilting at the bottom of the connecting rod 2. Several hooks 34 are connected to the top of the mounting base plate 31. The hooks 34 and the top of the mounting base plate 31 can be welded or detachably connected. The hooks 34 are designed in an "L" shape to facilitate limiting the position of the mounting base plate 31.

[0028] It should be noted that the connecting rod 2 is provided with a slot 21 for the hook 34 to slide, such as Figure 3 and Figure 4 As shown, the length of the insertion slot 21 is slightly longer than the shorter length of the hook 34. In use, the shorter side of the hook 34 is aligned with the insertion slot 21, and then lowered. The bottom of the insertion slot 21 has a limiting groove 22 for the hook 34 to insert into. Figure 3 and Figure 2 As shown, both the hook 34 and the limiting groove 22 have circular cross-sections. The diameter of the limiting groove 22 is larger than the diameter of the hook 34. When in use, the hook 34 and the limiting groove 22 are inserted after being lowered to limit the connection between the mounting base plate 31 and the connecting rod 2. The mounting base plate 31 is detachably connected to the bottom of the connecting rod 2 through the hook 34 and the limiting groove 22.

[0029] Specifically, during use, first connect the through groove in the mounting base plate 31 and the connecting rod 2, then move the mounting base plate 31 upwards. At this time, align the shorter side of the hook 34 with the insertion groove 21. Then move it downwards, and insert the hook 34 and the limiting groove 22 to limit the connection between the mounting base plate 31 and the connecting rod 2. Then connect the suction cup 32 at the bottom of the mounting base plate 31 and the fixing point of the tire removal device. At this time, the mounting base plate 31 and the connecting rod 2 will be fixed.

[0030] The fixing part 3 also includes a number of threaded grooves 33 connected to the fixing point of the mounting base plate 31 and the tire removal device by means of the threaded grooves 33 and fixing bolts. The threaded grooves 33 are distributed between two adjacent suction cups 32, and the threaded grooves 33 and the hooks 34 are staggered.

[0031] The effect achieved by the entire embodiment is as follows: First, the through groove in the mounting base plate 31 and the connecting rod 2 are fitted together. Then, the mounting base plate 31 is moved upward, and at this time, the shorter side of the hook 34 is aligned with the insertion groove 21. Then, it is moved downward, and at this time, the hook 34 and the limiting groove 22 are inserted to limit the connection between the mounting base plate 31 and the connecting rod 2. Then, the suction cup 32 at the bottom of the mounting base plate 31 is connected to the fixing point of the tire removal device. At this time, the mounting base plate 31 and the connecting rod 2 are fixed together. Then, the fixing point of the mounting base plate 31 and the tire removal device is installed through the threaded groove 33 and the fixing bolt. At this time, the mounting base plate 31 and the connecting rod The connection rod 2 and the connecting rod 32 are fixed together and will not fall off. The suction cup 32 is made of rubber for adsorption. The rubber material will help to initially position the connection rod during installation, reducing the difficulty of installation. It can also separate the bottom of the fixing base 1 from the disassembly device. When the fixing base 1 is in use, it will reduce the noise of the bottom of the connecting rod 2 and the disassembly device. At the same time, the suction cup 32 is equipped with four limit hooks, which are evenly distributed on the bottom of the connecting rod 2 to reduce the possibility of the bottom of the connecting rod 2 tilting. In addition, all the air inside the suction cup 32 will be expelled during use, further reducing the probability of the bottom of the connecting rod 2 tilting.

[0032] Example 2

[0033] like Figure 1-4 As shown, a wheel hub fixing chuck for tire mounting and dismounting has an integrally formed sliding groove 12 on the fixing chassis 1. The sliding groove 12 passes through the top and bottom of the fixing chassis 1 and is connected to the connecting rod 2.

[0034] A retractable cylinder 5 is installed inside the sliding groove 12. During use, the cylinder 5 is connected to an external power source. The working principle of the cylinder 5 is to convert the pressure energy of compressed air into mechanical energy, driving the mechanism to achieve reciprocating linear motion, oscillation, or rotational motion. The cylinder mainly consists of a cylinder body, piston, and sealing ring. Compressed air causes the piston to move, and the direction of piston rod movement is changed by altering the air intake direction. When selecting a model, a model suitable for the equipment should be chosen. The above is existing technology and will not be elaborated further below. The top of the cylinder 5 extends beyond the sliding groove 12.

[0035] The bottom of the sliding groove 12 is detachably connected to a mounting plate 52. Both the mounting plate 52 and the sliding groove 12 are circular. The diameter of the mounting plate 52 is smaller than the diameter of the sliding groove 12. The bottom of the mounting plate 52 and the sliding groove 12 are detachably connected by bolts.

[0036] The output end of cylinder 5 is detachably connected to a connecting block. When not in use, the connecting block is located on the fixed chassis 1. When in use, the tire is placed on the connecting block. Several grooves 51 are provided on the periphery of the connecting block. The grooves 51 and the connecting block are integrally molded.

[0037] A limiting hook 4 is rotatably connected inside the groove 51. When the connecting block is contracted by the cylinder 5, the limiting hook 4 will enter the sliding groove 12. After entering the sliding groove 12, the limiting hook 4 will contract under the diameter limit of the sliding groove 12. The contracted limiting hook 4 will fix the tire, which is convenient for the tire to be removed later. The end of the limiting hook 4 away from the groove 51 is designed as a hook to fix the tire and facilitate the later operation.

[0038] The fixed base 1 has a gap groove 11 for the folding of the limiting hook 4. The gap groove 11 extends through the top and bottom of the fixed base 1 and is used for the expansion and contraction of the limiting hook 4.

[0039] The effect achieved by the entire second embodiment is that when the connecting block is not in use, it is located on the fixed chassis 1. When in use, the tire is placed on the connecting block. When the connecting block is contracted by the cylinder 5, the limiting hook 4 will enter the sliding groove 12. After entering the sliding groove 12, the limiting hook 4 will contract under the diameter limit of the sliding groove 12. The contracted limiting hook 4 will fix the tire, which is convenient for the tire to be removed later. The end of the limiting hook 4 away from the groove 51 is designed as a hook to fix the tire and facilitate the later operation.

[0040] Working principle: When using the wheel hub fixing chuck for tire removal and assembly, an external power supply is connected. First, the through groove in the mounting base plate 31 and the connecting rod 2 are fitted together. Then, the mounting base plate 31 is moved upward, and the shorter side of the hook 34 is aligned with the insertion groove 21. Then, it is moved downward, and the hook 34 is inserted into the limiting groove 22 to limit the connection between the mounting base plate 31 and the connecting rod 2. Then, the suction cup 32 at the bottom of the mounting base plate 31 is connected to the fixing point of the tire removal device. At this time, the mounting base plate 31 and the connecting rod 2 are fixed together. Finally, the mounting base plate 31 and the fixing point of the tire removal device are installed through the threaded groove 33 and the fixing bolt. At this time, the mounting base plate... The connection between 31 and the connecting rod 2 will be fixed and will not fall off. The suction cup 32 is made of rubber for adsorption. The rubber material will provide initial positioning during installation, reducing the difficulty of installation. On the other hand, it can separate the bottom of the fixing base 1 from the disassembly device. When the fixing base 1 is in use, it will reduce the noise of the bottom of the connecting rod 2 and the disassembly device. At the same time, the suction cup 32 is equipped with 4 limit hooks, which are evenly distributed on the bottom of the connecting rod 2 to reduce the tilting of the bottom of the connecting rod 2. In addition, all the air inside the suction cup 32 will be discharged during use, further reducing the probability of the bottom of the connecting rod 2 tilting.

[0041] Secondly, when not in use, the connecting block is located on the fixed chassis 1. When in use, the tire is placed on the connecting block. When the connecting block is contracted by the cylinder 5, the limiting hook 4 will enter the sliding groove 12. After entering the sliding groove 12, the limiting hook 4 will contract under the diameter limit of the sliding groove 12. After contraction, the limiting hook 4 will fix the tire, which is convenient for tire removal later. The end of the limiting hook 4 away from the groove 51 is designed as a hook to fix the tire, which is convenient for later operations. Finally, the work of the wheel hub fixing chuck for tire installation and removal is completed.
