DETAILED DESCRIPTION

[0026] See also Figure 1-3 In this embodiment, a hanging cage for sandblasting a gear shaft includes a counterweight block 1, a support rod 2 fixedly connected to the top of the counterweight block 1, a connecting ring 3 fixedly connected to the outside of the support rod 2, a hanging ring 4 fixedly connected to the top of the support rod 2, a limiting mechanism arranged on the connecting ring 3, and a limiting component arranged on the connecting ring 3.

[0027] It should be noted that, by providing the hanging ring 4, it is convenient to place the hanging cage inside the sandblasting machine.

[0028] See also Figure 1 In this embodiment, the limiting mechanism includes a box body 5 fixedly connected to the bottom of the top connecting ring 3, a worm 6 rotatably connected to the inside of the box body 5, a threaded rod 7 rotatably connected to the top wall of the box body 5, a worm wheel 8 fixedly connected to the outside of the threaded rod 7 and meshing with the worm 6, a movable block 9 threadedly connected to the outside of the threaded rod 7, a support block 10 fixedly connected to the left and right sides of the movable block 9, and a first limiting block 11 rotatably connected to the bottom of the movable block 9. A turning handle 16 for convenient rotation is fixedly connected to the worm 6. A threaded groove is provided on the top of the movable block 9. The inside of the threaded groove is threadedly connected to the outside of the threaded rod 7. Support grooves are provided on both sides of the inner wall of the box body 5. The inside of the support groove is slidably connected to the outside of the support block 10, and the bottom of the box body 5 is open.

[0029] It should be noted that in order to achieve the effect of limiting the gear shaft, it is convenient to limit the gear shafts of different sizes. By setting the worm wheel 8 and the worm 6, the limiting mechanism has self-locking properties, thereby increasing the stability when limiting the gear shaft.

[0030] See also Figure 2-3In this embodiment, the limiting assembly includes a sleeve 12 fixedly connected to the top of the bottom connecting ring 3, a limiting spring 13 fixedly connected to the inside of the sleeve 12, a support plate 14 fixedly connected to the top of the limiting spring 13, and a second limiting block 15 rotatably connected to the top of the support plate 14. A sliding through hole is opened at the top of the sleeve 12, and the inside of the sliding through hole is slidably connected to the outer side of the second limiting block 15.

[0031] It should be noted that increasing the limiting effect on the gear shaft further increases the stability when limiting the gear shaft.

[0032] The working principle of the above embodiment is as follows: when in use, the handle 16 is placed on the top of the second limit block 15, and then the handle 16 is turned, the handle 16 drives the worm 6 to rotate, the worm 6 drives the worm wheel 8 to rotate, the worm wheel 8 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the movable block 9 to move downward. By setting the support block 10 and the support groove, the stability of the movable block 9 during movement is increased, so that the movable block 9 drives the first limit block 11 to move downward to limit and fix the top of the gear shaft. The worm 6 and the worm wheel 8 have self-locking properties, which increases the stability of the first limit block 11 when it is limited and fixed. At the same time, the limit spring 13 is extended to squeeze the support plate 14, the support plate 14 squeezes the second limit block 15, and the second limit block 15 squeezes the gear shaft, thereby increasing the stability of the second limit block 15 when limiting the gear shaft. The first limit block 11 and the second limit block 15 are rotatably arranged to facilitate self-rotation when sandblasting the gear shaft, thereby facilitating the improvement of the uniformity of the gear shaft during sandblasting, facilitating the use of the user, and improving the practicality of the hanging cage.
