The gear oil inside the installation box can enter the interior of the filter box through two sets of connecting pipes. The impurities inside the gear oil will be intercepted by the inclined filter screen, and the gear oil will drip onto the inclined surface of the inclined block. At this time, the first sealing plug is pulled out, and the impurities can be removed through the first opening. The second sealing plug is pulled out, and the gear oil can be removed through the second opening. The filter box is set up to prevent the gear structure from being contacted and adsorbed by foreign objects. At the same time, it has a collection structure, which can collect the dripping gear oil, thereby improving the practicality of the rotary switch device.

The air pump can fill the air into the interior of the air storage box through the air guide pipe. This part of the air can push the piston. During the movement of the piston, the four groups of support columns will gradually move out of the interior of the air storage box. When the length of the four groups of support columns moved out of the air storage box reaches an appropriate value, the right group of control valves are closed and the air pump is stopped at the same time. At this time, the four groups of second ball sockets and the four groups of second balls can be used to move and use the installation box.

[0037] In one embodiment, a breathable mesh 34 is fixedly passed through the lower portion of the air storage box 12 .

[0038] Working principle:

[0039] When the rotary switch device is actually used, the control panel is used to make the deceleration self-locking motor 9 work. The output end of the deceleration self-locking motor 9 can drive the gear 10 to rotate. Since the gear 10 and the outer gear ring 7 are meshed with each other, the rotating gear 10 can push the outer gear ring 7 to rotate. The rotating outer gear ring 7 can drive the rotating disk 5 and the guide track plate 6 to rotate through the rotating shaft 4. When the guide track plate 6 rotates to a suitable position, the deceleration self-locking motor 9 is stopped. In this process, the multiple groups of first balls 16 are subjected to the friction of the mounting box 1 and are respectively inside the multiple groups of first ball sockets 15. Since the surfaces of the multiple groups of first balls 16 are smooth, it is possible to prevent the mounting box 1 from obstructing the rotating tube. 14 is used for rotation. During this process, the installation box 1 and the rotating tube 14 can intercept foreign objects to prevent them from contacting the gear 10 and the outer gear ring 7. When gear oil needs to be applied, the gear oil can be dripped into the annular plate 32. The annular bevel 33 can guide the gear oil. The gear oil can pass through the through hole 3. The gear oil along the rotating shaft 4 will contact the outer gear ring 7 and the gear 10. The gear oil inside the installation box 1 can enter the interior of the filter box 11 through the two sets of connecting pipes 23. The impurities inside the gear oil will be intercepted by the inclined filter 17, and the gear oil will drip on the inclined surface of the inclined block 18. At this time, the first sealing plug 20 is pulled out and the impurities can be removed through the first opening 19 , pull out the second sealing plug 22, and the gear oil can be removed through the second opening 21. The filter box 11 is provided to prevent the gear 10 structure from being contacted and adsorbed by foreign objects. At the same time, it has a collection structure to collect the dripping gear oil, thereby improving the practicality of the rotary switch device. At the same time, when it is necessary to move and use the installation box 1, the control panel is used to make the air pump 24 work. The air pump 24 can fill the air into the interior of the air storage box 12 through the air guide pipe 25. This part of the air can push the piston 28. During the movement of the piston 28, the four groups of support columns 29 will gradually move out of the interior of the air storage box 12. When the four groups of support columns 29 move out of the air storage box When the length of the box 12 reaches an appropriate value, close the right set of control valves 27 and stop the air pump 24 at the same time. At this time, the four sets of second ball sockets 30 and the four sets of second balls 31 can be used to move and use the installation box 1. When the installation box 1 is moved to a suitable position, open and close the left set of control valves 27. Under the action of gravity, the four sets of support columns 29 will gradually return to the interior of the air storage box 12. The piston 28 can discharge the air inside the air storage box 12 through the air outlet pipe 26. The breathable net 34 provides protection for the up and down movement of the piston 28. Through the set air storage box 12, the guide track plate 6 can be conveniently moved and used, which brings convenience to the mobile use of the rotary switch device.
