Electricity is generated through the rotation of motors and small AC generators that use permanent magnets to generate magnetic fields, and the rotation of rotors and stators to generate electricity.

[0003] For example, in the Chinese patent document with publication number CN213846371U, a rotor shaft is included, the surface of the rotor shaft is sleeved with uniformly distributed magnetic cores, and the outer diameter of the magnetic cores is provided with uniformly distributed positioning grooves, the surface of the rotor shaft is sleeved with a first limit plate and a second limit plate, and the first limit plate and the second limit plate are respectively located on both sides of the magnetic core and are symmetrically distributed. This technical solution has a novel structure, and the device not only improves the stability of the magnetic core during rotation, but also improves the stability of the motor; it also has high stability and safety in use.

[0004] However, after the positioning rod and the locking seat are installed in the above technical solution, the locking spring is operated to push the positioning pin to fix the positioning rod, which results in cumbersome operation steps, complex structure and high cost. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a plastic magnetic rotor structure of a motor, and a limiting ring which is threadedly connected to the fixing column and the limiting cylinder is moved to the outside of the fixing column, so that the fixing column can be limited and fixed with the help of the limiting ring, and because the cross-section of the limiting plate and the cross-section of the limiting groove are both set to be rectangular, the limiting cylinder can limit the connected fixing column, positioning column and limiting plate, and prevent the positioning column from rotating and causing the fixing column and the limiting ring to separate, thereby enhancing the connection stability between the positioning column and the support plate, and the utility model has a simple structure and is easy to operate, so as to solve the problems arising from the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a motor plastic magnetic rotor structure, comprising a rotor shaft, two support plates are sleeved on the outside of the rotor shaft, a plurality of magnetic cores are arranged between the two support plates, and a positioning assembly for fixing the plurality of magnetic cores is arranged between the two support plates;

[0007] The positioning assembly includes a plurality of positioning posts distributed at intervals, and the plurality of positioning posts are arranged between two support plates. Fixed posts are installed at both ends of the positioning post, and a limiting plate is installed at one end of the fixing post away from the positioning post. A limiting cylinder is sleeved on the outside of the limiting plate, and a limiting groove is arranged inside the limiting cylinder. The cross-sections of the limiting plate and the limiting groove are both set to be rectangular. A limiting ring is sleeved on the outside of one end of the limiting plate close to the fixing post, and one end of the limiting ring away from the limiting cylinder is sleeved on the outside of the fixing post, and the inner wall of the limiting ring is threadedly connected to the fixing post and the outside of the limiting cylinder.

[0008] A fixing hole is provided on one side of the support plate close to the fixing column, and the fixing column is arranged inside the fixing hole.

[0009] In a preferred embodiment, a fixing bracket is installed at one end of the limiting cylinder away from the fixing column, and one end of the fixing bracket away from the limiting cylinder is connected to the support plate. Through the connection between the fixing bracket and the support plate, the fixing bracket can support and fix the limiting cylinder to ensure the stability of the limiting cylinder.

[0010] In a preferred embodiment, a positioning groove is provided on one side of the magnetic core close to the positioning column, and the positioning column is arranged inside the positioning groove. Through the cooperation between the positioning groove and the positioning column, the positioning column can limit the magnetic core to ensure the stability of the magnetic core.

[0011] In a preferred embodiment, the diameter of the limiting cylinder is equal to the diameter of the fixing column, and the width of the limiting plate is smaller than the diameter of the fixing column. By setting the diameter of the limiting cylinder equal to the diameter of the fixing column, the limiting ring can move outside the limiting cylinder and the fixing column at the same time, and the width of the limiting plate is set to be smaller than the diameter of the fixing column, so that the limiting plate will not hinder the connection between the fixing column and the limiting cylinder.

[0012] In a preferred embodiment, the inner diameter of the limiting ring is equal to the diameter of the fixing column and the diameter of the limiting cylinder. By setting the inner diameter of the limiting ring equal to the diameter of the fixing column and the limiting cylinder, the limiting ring can be connected to the fixing column and the limiting cylinder at the same time.

[0013] In a preferred embodiment, the diameter of the fixing column is smaller than the diameter of the positioning column. By setting the diameter of the fixing column to be smaller than the diameter of the positioning column, the two support plates can limit the two ends of the positioning column.

[0014] Technical effects and advantages of the utility model:

[0015] By moving the limiting ring threadedly connected to the fixing column and the limiting cylinder to the outside of the fixing column, the fixing column can be limited and fixed with the help of the limiting ring. Because the cross-section of the limiting plate and the cross-section of the limiting groove are both set to be rectangular, the limiting cylinder can limit the connected fixing column, positioning column and limiting plate to prevent the positioning column from rotating and causing the fixing column and the limiting ring to separate. This can enhance the connection stability between the positioning column and the support plate. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Refer to the instruction manual Figure 1-5 The utility model provides a motor plastic magnetic rotor structure, comprising a rotor shaft 1, wherein two support plates 2 are sleeved on the outside of the rotor shaft 1, a plurality of magnetic cores 3 are arranged between the two support plates 2, and a positioning assembly for fixing the plurality of magnetic cores 3 is arranged between the two support plates 2;

[0024] like Figure 1-5As shown, the positioning assembly includes a plurality of positioning columns 4 distributed at intervals, and the plurality of positioning columns 4 are arranged between two support plates 2. Fixed columns 5 are installed at both the front and rear ends of the positioning columns 4. A limiting plate 6 is installed at the end of the fixing column 5 away from the positioning column 4. A limiting tube 7 is sleeved on the outside of the limiting plate 6, and a limiting groove 8 is provided inside the limiting tube 7. The cross-sections of the limiting plate 6 and the limiting groove 8 are both rectangular. A limiting ring 9 is sleeved on the outside of the limiting plate 6 close to the fixing column 5, and the end of the limiting ring 9 away from the limiting tube 7 is sleeved on the outside of the fixing column 5. The inner wall of the limiting ring 9 is threadedly connected to the fixing column 5 and the outside of the limiting tube 7; a fixing hole 10 is provided on the side of the support plate 2 close to the fixing column 5, and the fixing column 5 is arranged inside the fixing hole 10.

[0025] Specifically, by moving the limiting ring 9 threadedly connected to the fixing column 5 and the limiting cylinder 7 to the outside of the fixing column 5, the fixing column 5 can be limited and fixed with the help of the limiting ring 9, and because the cross-section of the limiting plate 6 and the cross-section of the limiting groove 8 are both set to be rectangular, the limiting cylinder 7 can limit the connected fixing column 5, positioning column 4 and limiting plate 6 to prevent the positioning column 4 from rotating and causing the fixing column 5 to separate from the limiting ring 9, thereby enhancing the connection stability between the positioning column 4 and the support plate 2.

[0026] like Figure 1 , 3 As shown in Figures 4 and 5, a fixing bracket 11 is installed at one end of the limiting cylinder 7 away from the fixing column 5, and one end of the fixing bracket 11 away from the limiting cylinder 7 is connected to the support plate 2. Through the connection between the fixing bracket 11 and the support plate 2, the fixing bracket 11 can support and fix the limiting cylinder 7 to ensure the stability of the limiting cylinder 7.

[0027] like Figure 2 As shown, a positioning groove 12 is provided on one side of the magnetic core 3 close to the positioning column 4, and the positioning column 4 is arranged inside the positioning groove 12. Through the cooperation between the positioning groove 12 and the positioning column 4, the positioning column 4 can limit the magnetic core 3 to ensure the stability of the magnetic core 3.

[0028] like Figure 4 and 5As shown, the diameter of the limiting cylinder 7 is equal to the diameter of the fixing column 5, and the width of the limiting plate 6 is smaller than the diameter of the fixing column 5. By setting the diameter of the limiting cylinder 7 to be equal to the diameter of the fixing column 5, the limiting ring 9 can move outside the limiting cylinder 7 and the fixing column 5 at the same time, and the width of the limiting plate 6 is set to be smaller than the diameter of the fixing column 5, so that the limiting plate 6 will not hinder the connection between the fixing column 5 and the limiting cylinder 7. The inner diameter of the limiting ring 9 is equal to the diameter of the fixing column 5 and the diameter of the limiting cylinder 7. By setting the inner diameter of the limiting ring 9 to be equal to the diameter of the fixing column 5 and the limiting cylinder 7, the limiting ring 9 can be connected to the fixing column 5 and the limiting cylinder 7 at the same time. The diameter of the fixing column 5 is smaller than the diameter of the positioning column 4. By setting the diameter of the fixing column 5 to be smaller than the diameter of the positioning column 4, the two support plates 2 can limit the two ends of the positioning column 4.

[0029] First, the fixing columns 5 at both ends of the positioning column 4 are respectively embedded in the fixing holes 10 on the two support plates 2, and the limiting plate 6 is embedded in the limiting groove 8 in the limiting tube 7, and then the limiting ring 9 threadedly connected to the fixing column 5 and the limiting tube 7 is operated to move to the outside of the fixing column 5, so that the fixing column 5 can be limited and fixed with the help of the limiting ring 9, thereby enhancing the connection stability between the positioning column 4 and the support plate 2. Because the cross-section of the limiting plate 6 and the cross-section of the limiting groove 8 are both set to be rectangular, the limiting tube 7 can limit the connected fixing column 5, positioning column 4 and limiting plate 6, to prevent the positioning column 4 from rotating and causing the fixing column 5 to separate from the limiting ring 9, thereby ensuring the connection stability between the limiting ring 9 and the fixing column 5.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
