[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: a safety anti-touch structure of a power regulator, including an electrical cabinet body 1, a power regulator body 3 is installed inside the electrical cabinet body 1, and an anti-touch component 2 is arranged on the outer wall of the power regulator body 3;

[0025] The anti-touch component 2 includes a protective cover 22 sleeved on the outer wall of the power regulator body 3. A connecting plug rod 21 is fixed on the protective cover 22. A groove is formed at the top of the connecting plug rod 21, and reverse teeth 29 are arranged inside the groove. The reverse teeth 29 are horizontally equidistantly distributed with respect to the groove. One end of a limiting rod 28 is supported on the reverse teeth 29 in this structure. The connecting plug rod 21 and the sleeve 26 are slidably connected, and the sleeve 26 is in a "T" - shaped structure in cross - section. The sleeve 26 in this structure is fixed on the inner wall of the electrical cabinet body 1 by screws. By the sliding connection between the connecting plug rod 21 and the sleeve 26, the installation depth of the protective cover 22 can be adjusted, and at the same time, the quick connection and disassembly of the protective cover 22 and the electrical cabinet body 1 can be realized. One set of connecting plug rods 21 is arranged on each side of the protective cover 22, and the connecting plug rod 21 is fixedly connected to the protective cover 22. In this structure, the protective cover 22 can be connected to the electrical cabinet body 1 by inserting the connecting plug rod 21 into the sleeve 26. A through - hole is formed on the electrical cabinet body 1. One end of the through - hole is fixed with a sleeve 26. A knob 24 is arranged on the outer wall of the sleeve 26. A rotating shaft 27 is rotatably connected to the inner wall of the sleeve 26. A limiting block 23 and a limiting rod 28 are fixedly connected to the outer wall of the rotating shaft 27. One end of the rotating shaft 27 penetrates through the sleeve 26 and is connected to the knob 24. In this structure, by rotating the knob 24 on the outer wall of the sleeve 26, the rotating shaft 27 and the limiting rod 28 can be driven to rotate, so as to realize the adjustment of the angle of the limiting rod 28. One limiting block 23 is arranged on each of the left and right sides of the limiting rod 28, and the limiting rod 28 is in an inclined structure. Torsion springs 25 are sleeved on both sides of the rotating shaft 27. One end of the torsion spring 25 is connected to the limiting block 23, and the other end of the torsion spring 25 is connected to the inner wall of the sleeve 26. In this structure, by arranging the torsion springs 25, the rotating shaft 27 and the limiting rod 28 can be in a fixed angle, so that one end of the limiting rod 28 is in close contact with the reverse teeth 29. At this time, the connecting plug rod 21 can only be pushed into the sleeve 26 and cannot move out of the sleeve 26. When the rotating shaft 27 and the limiting rod 28 are rotated, the limiting rod 28 can be driven to move away from the reverse teeth 29, so as to facilitate pulling out the connecting plug rod 21 from the sleeve 26. One end of the connecting plug rod 21 penetrates through the sleeve 26 and is movably connected to the electrical cabinet body 1, and the protective cover 22 is made of a visible material.

[0026] Working principle: When using the safety anti-touch structure of the power regulator, first fix the sleeve 26 to the through hole on the inner wall of the electrical cabinet body 1 with screws. Then align the connecting plug rod 21 on the protective cover 22 with the sleeve 26. Subsequently, insert one end of the connecting plug rod 21 into the sleeve 26 and push the connecting plug rod 21 to position the protective cover 22 at an appropriate location. During the process of pushing the protective cover 22 and the connecting plug rod 21, the reverse teeth 29 on the connecting plug rod 21 push the limit rod 28 and the rotating shaft 27 to rotate, enabling the connecting plug rod 21 to move smoothly. When the pushing of the connecting plug rod 21 stops, the limit rod 28 and the rotating shaft 27 cause the limit rod 28 to fit tightly with the reverse teeth 29 under the action of the torsion spring 25. During the use of this device, the working state of the power regulator body 3 can be directly viewed through the protective cover 22. If it is necessary to remove the protective cover 22, rotate the knob 24, which drives the limit rod 28 and the rotating shaft 27 to rotate, causing the limit rod 28 to move away from the reverse teeth 29. Subsequently, the connecting plug rod 21 and the protective cover 22 can be pulled backward to separate the connecting plug rod 21 from the sleeve 26.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
