[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 3 A motor rotor with a protective structure includes a motor rotor body 1. In order to facilitate stable protection of the motor rotor body 1, a protective device is provided on the outside of the motor rotor body 1. The protective device includes a protective tube 2, two arc plates 3 and two limiting rings 4. The protective tube 2 wraps the motor rotor body 1 in the middle, the arc plate 3 is installed on the inner side of the protective tube 2, and the two limiting rings 4 clamp the arc plate 3 in the middle.

[0023] In order to facilitate the installation of the protective cylinder 2, the motor rotor body 1 includes a rotating shaft 11 and a steel frame 12. The steel frame 12 is installed on the outer surface of the rotating shaft 11. The two arc plates 3 are slidingly connected to the outer surface of the rotating shaft 11. The two arc plates 3 are horizontally symmetrically distributed with the axis of the rotating shaft 11 as the center of symmetry. The arc plate 3 on the right is rotatably connected to the inside of the arc plate 3. The arc plate 3 slides outside the rotating shaft 11 to facilitate the installation of the protective cylinder 2. The rotating rod 31 can rotate stably inside the arc plate 3.

[0024] In order to facilitate the stable installation of the two arc plates 3 on the outside of the rotating shaft 11, a swing plate 32 is fixedly installed on the outer surface of the rotating rod 31. The internal thread of the swing plate 32 is connected with a mounting screw 33. The mounting screw 33 passes through the inside of the swing plate 32 and is connected with the internal thread of the arc plate 3 on the left. The swing plate 32 can swing automatically. The mounting screw 33 is used to stably fix the swing plate 32 on the outside of the arc plate 3, so that the swing plate 32 stably connects the two arc plates 3, so that the two arc plates 3 are stably installed on the outside of the rotating shaft 11.

[0025] In order to ensure that the position of the arc plate 3 outside the motor rotor body 1 remains unchanged, the two limiting rings 4 are slidably connected to the outer surface of the motor rotor body 1, and the outer surfaces of the two limiting rings 4 are tightly attached to the outer surface of the arc plate 3. The two limiting rings 4 are horizontally symmetrically distributed with the axis of the arc plate 3 as the center of symmetry. A mounting plate 13 is fixedly installed on the outer surface of the motor rotor body 1. The two limiting rings 4 clamp the arc plate 3 in the middle, so that the position of the arc plate 3 outside the motor rotor body 1 remains unchanged.

[0026] In order to maintain the position of the arc plate 3 outside the motor rotor body 1, the internal thread of the mounting plate 13 is connected to the adjusting rod 14, and the front end outer surface of the adjusting rod 14 is fixedly installed with a mounting ring 15. The front end surface of the adjusting rod 14 is connected to the internal rotation of the limiting ring 4, and the outer surface of the mounting ring 15 is connected to the internal rotation of the limiting ring 4. When the adjusting rod 14 is rotated, the adjusting rod 14 will move horizontally inside the mounting plate 13, and the mounting ring 15 will be stuck in the limiting ring 4 and rotated to ensure that the adjusting rod 14 will not fall out of the limiting ring 4.

[0027] In order to facilitate the stable installation of the protective tube 2 on the outside of the motor rotor body 1, the protective tube 2 is slidably connected to the outer surface of the arc plate 3, and the internal thread of the protective tube 2 is connected to the limit screw 21. The limit screw 21 passes through the inside of the protective tube 2 and is connected to the internal thread of the arc plate 3. The two limit screws 21 are distributed in a circular array with the axis of the rotating shaft 11 as the array center. The limit screws 21 stably install the protective tube 2 on the outside of the arc plate 3, allowing the protective tube 2 to be stably installed on the outside of the motor rotor body 1.

[0028] By setting up a protective device, when protecting the motor rotor body 1, the protective tube 2 and the arc plate 3 are installed on the outside of the motor rotor body 1. During installation, the mounting screw 33 is first installed through the swing plate 32 in the arc plate 3 so that the two arc plates 3 fit tightly together, and then the adjusting rod 14 is rotated to control the limit ring 4 to move horizontally outside the rotating shaft 11, so that the two limit rings 4 tightly clamp the arc plate 3 to stabilize the position of the arc plate 3, and then the protective tube 2 is put on the outside of the arc plate 3, and then the protective tube 2 is limited by the limit screw 21, so that the protective tube 2 is stably installed on the outside of the arc plate 3, thereby protecting the inner motor rotor body 1, thereby achieving the effect of preventing the motor rotor protection mechanism from falling off.

[0029] Working principle: When protecting the motor rotor body 1, the protective tube 2 and the arc plate 3 are installed on the outside of the motor rotor body 1. During installation, first pass the mounting screw 33 through the swing plate 32 and install it in the arc plate 3, so that the two arc plates 3 fit tightly together, and then rotate the adjusting rod 14 to control the limit ring 4 to move horizontally outside the rotating shaft 11, so that the two limit rings 4 can tightly clamp the arc plate 3 to stabilize the position of the arc plate 3, and then put the protective tube 2 on the outside of the arc plate 3, and then use the limit screw 21 to limit the protective tube 2, so that the protective tube 2 can be stably installed on the outside of the arc plate 3, thereby protecting the inner motor rotor body 1.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
