[0016] In order to more easily understand the structure of the present invention and the functional features and advantages that can be achieved, the following will describe the preferred embodiments of the present invention in detail in conjunction with the drawings as follows:
[0017] Embodiment:
[0018] As Figures 1 to 4As shown in the figure, the utility model provides a half - shaft nut disassembly device, which includes a rotating cylinder 1. One end of the cylinder 1 is detachably connected with a disassembly part 2 for fitting with the half - shaft nut, so as to drive the disassembly part 2 to rotate by the rotation of the cylinder 1. Further, the disassembly part 2 is of a cylindrical structure. The other end of the cylinder 1 is provided with a rotating part 3 for manual rotation. The rotating part 3 serves as an extension arm to increase the force arm, thereby reducing the force required to rotate the cylinder 1. A locking hole 21 is provided on the side of the disassembly part 2, and a locking part 4 for inserting into the locking hole 21 is provided on the side of the cylinder 1. In this application, the manually rotatable rotating part 3 is used to increase the force arm, enabling the easy disassembly of half - shaft nuts of different sizes.
[0019] See Figure 1 and Figure 2 , one end of the disassembly part 2 of this application is provided with an external thread 22, and the end of the cylinder 1 is provided with an internal thread 11. The disassembly part 2 is connected to the internal thread 11 through the external thread 22, so that the disassembly part 2 is detachably connected to the cylinder 1.
[0020] See Figure 2 , one end of the disassembly part 2 of this application is provided with a polygonal socket hole 23 for fitting with the half - shaft nut.
[0021] See Figure 2 , there are multiple disassembly parts 2 in this application. Different - sized polygonal socket holes 23 are respectively provided on the multiple disassembly parts 2, so as to facilitate the disassembly and replacement of the disassembly parts 2 with different - sized polygonal socket holes 23; by providing multiple disassembly parts 2 of different sizes, the disassembly of half - shaft nuts of different sizes for different vehicle models can be carried out. Compared with ordinary sleeves, it does not need to be equipped with an air pipe; due to the relatively long force arm of its rotating part 3, the force used to rotate and disassemble the half - shaft nut is relatively small.
[0022] See Figure 2 , the polygonal socket hole 23 of this application is hexagonal or pentagonal to fit pentagonal or hexagonal half - shaft nuts.
[0023] As another embodiment of this application, as Figure 4 shown, the locking part 4 of this application is threadedly connected to the side of the cylinder 1. The end of the locking part 4 is provided with a plug - in part 41. After the disassembly part 2 is connected to the cylinder 1, the locking hole 21 and the plug - in part 41 are horizontally aligned. The locking part 4 rotates to make the plug - in part 41 inserted into the locking hole 21 to lock the rotational freedom of the disassembly part 2.
[0024] See Figure 4 , the side of the cylinder 1 of this application is provided with a groove 12, and a threaded through - hole is provided in the groove 12. The locking part 4 is threadedly connected to the threaded through - hole. The locking part 4 rotates to make the plug - in part 41 inserted into the locking hole 21, so as to place the end of the locking part 4 in the groove 12.
[0025] See Figure 2 and Figure 4 On the locking member 4, there are protrusions or strip grooves provided, so as to rotate the locking member 4 through the protrusions or strip grooves.
[0026] As another embodiment of the present application, as Figure 2 shown, on both sides of one end face of the rotating cylinder 1 of the present application, vertical rods 5 are fixedly provided. The end of the vertical rod 5 is connected with a sleeve 6. The rotating member 3 is a rotating handle, and the rotating handle is inserted into the sleeve 6, and the rotating cylinder 1 is driven to rotate by the rotating handle; further, a limiting portion is provided at one end or both ends of the rotating handle to prevent the rotating handle from sliding and falling off from the sleeve 6 or one side of the sleeve 6.
[0027] The working principle of the present application: When in use, select a disassembly member 2 of different specifications according to the half shaft nuts of different sizes. After connecting the disassembly member 2 to the rotating cylinder 1, make the lock hole 21 on the disassembly member 2 horizontally face the locking member 4 directly, so as to facilitate rotating the locking member 4 to make the plugging portion 41 at the end be plugged into the lock hole 21; insert the rotating handle into the sleeve 6, and then rotate the rotating handle to drive the rotating cylinder 1 to rotate, so that the rotating cylinder 1 drives the disassembly member 2 to disassemble the half shaft nut therein from the brake disc.
[0028] The above is only the preferred embodiment of the present utility model, and does not impose any form of limitation on the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above technical content within the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes.
