[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] Reference Figure 1-3The utility model provides an embodiment: a riveted core stability structure, including an iron core body 1, a plurality of connecting plates 4 are evenly fixedly connected to the outside of the iron core body 1, a key tooth 5 is fixedly connected to the end of the connecting plate 4 away from the iron core body 1, an axial hole 7 is opened in the middle of the iron core body 1, a rotating shaft 2 is slidably connected inside the axial hole 7, a fixing plate 3 is fixedly connected to the rear outside of the rotating shaft 2, a limiting hole 10 is opened inside the fixing plate 3, a stabilizing component is arranged on the inner side around the iron core body 1, a limiting component is arranged on the outer side of the rotating shaft 2, the stabilizing component includes a mounting hole 9, an insulating sleeve 11 and a rivet body 12, the mounting hole 9 is opened around the inside of the iron core body 1, the insulating sleeve 11 is fixedly connected inside the mounting hole 9, the rivet body 12 is slidably connected inside the insulating sleeve 11, the rear side of the rivet body 12 is slidably connected in the limiting hole 10, and the mounting hole 9 is located directly in front of the limiting hole 10.

[0024] When the stability of the core body 1 needs to be improved, the rotating shaft 2 is pulled to make the rotating shaft 2 slide inside the shaft hole 7. The sliding of the rotating shaft 2 drives the fixing plate 3 to move, so that the limiting hole 10 moves to the rear side of the mounting hole 9, and then the rivet body 12 is pushed to make the rivet body 12 slide inside the insulating sleeve 11 until the rear end of the rivet body 12 slides into the limiting hole 10. In this way, the riveted core stability structure can improve the stability of the core body 1, ensure that the core remains stable during operation, and prevent loosening or displacement due to vibration or other external factors.

[0025] Reference Figure 1-3 The limit assembly includes a clamping block 6 and a clamping interface 8. The clamping block 6 is fixedly connected to the left and right sides of the upper part of the rotating shaft 2. The clamping interface 8 is opened on the left and right sides of the upper part of the shaft hole 7. The clamping block 6 is slidably connected inside the clamping interface 8.

[0026] The rotation of the rotating shaft 2 drives the clamping block 6 to rotate, and the rotation of the clamping block 6 drives the core body 1 to rotate through the shaft hole 7.

[0027] Working principle: When the stability of the core body 1 needs to be improved, pull the rotating shaft 2 to make the rotating shaft 2 slide inside the shaft hole 7. The sliding of the rotating shaft 2 drives the fixing plate 3 to move, so that the limiting hole 10 moves to the rear side of the mounting hole 9, and then push the rivet body 12 to make the rivet body 12 slide inside the insulating sleeve 11 until the rear end of the rivet body 12 slides to the inside of the limiting hole 10. In this way, the riveted core stability structure can improve the stability of the core body 1, ensure that the core remains stable during operation, and prevent loosening or displacement due to vibration or other external factors.
