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.

[0022] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a power frequency withstand voltage detector for power equipment with a protection function, including a protective cover 1, a card slot 2, a card block 3, a docking block 4, a protective pad 5, a bolt 6, a linkage block 7, a moving button 8, a connecting column 9, a spring 10, a rotating rod 11, a fixing bolt 12, a body 13, a bottom plate 14, a clamping plate 15, a turntable 16 and a threaded rod 17. A card slot 2 is opened inside the protective cover 1. There are two card slots 2, and the two card slots 2 are symmetric with respect to the horizontal center line of the protective cover 1, and the opening end of the card slot 2 is in a "T" shape. The internal dimensions of the card slot 2 match the dimensions of the card block 3 and the docking block 4. By docking the card block 3 and the docking block 4 with the card slot 2, the protective pad 5 can be installed into the card slot 2 of the protective cover 1 through the docking block 4 and the card block 3. The card slot 2 is internally connected with a card block 3;

[0023] One side of the clamping block 3 is fixedly connected with a docking block 4. There are two docking blocks 4, and the two docking blocks 4 are respectively vertically connected to both sides of the protective pad 5. And the outer layer of the protective pad 5 is made of latex material. One side of the docking block 4 away from the protective pad 5 is vertically connected to the clamping block 3. When the protective pad 5 is installed inside the protective cover 1, when the protective cover 1 is squeezed, it will not directly cause damage to the machine body 13. One side of the docking block 4 is connected with the protective pad 5. One end of the bolt 6 is connected with the protective cover 1. The end of the bolt 6 away from the protective cover 1 is connected with a linkage block 7. The top of the linkage block 7 is connected with a moving knob 8. The outer wall of the moving knob 8 is movably connected with a connecting column 9. There are two groups of connecting columns 9, and each group of connecting columns 9 internally connects a linkage block 7 and a spring 10 respectively. And the bolt 6, the linkage block 7, the moving knob 8, the connecting column 9 and the spring 10 and the protective cover 1 are elastically snap-connected, so that the bolt 6 is snapped into the protective cover 1. In this way, the protective cover 1 can be fixed in the open or closed state through the rotating rod 11, thereby preventing the protective cover 1 from accidentally closing. The spring 10 is connected inside the connecting column 9. One end of the connecting column 9 is fixedly connected with a rotating rod 11;

[0024] The bottom of the rotating rod 11 movably penetrates and is connected with a fixing bolt 12. One end of the fixing bolt 12 is threadedly connected to the machine body 13. The bottom of the machine body 13 is connected with a bottom plate 14. There are two groups of bottom plates 14, and the two groups of bottom plates 14 are located at the same horizontal position at the bottom of the machine body 13. And a recessed rectangular notch is opened at the bottom of each bottom plate 14. A clamping plate 15 is respectively arranged inside the notch of each bottom plate 14. A turntable 16 and a threaded rod 17 are respectively connected to the top of each clamping plate 15. In this way, the corresponding threaded rod 17 can drive the corresponding turntable 16 and the clamping plate 15 to move up and down inside the bottom plate 14 to meet the actual use requirements. The bottom plate 14 is movably fitted with the clamping plate 15 at the bottom. The clamping plate 15 is movably connected with the turntable 16 inside. The surface of the turntable 16 is fixedly connected with a threaded rod 17. The threaded rod 17 vertically penetrates the bottom plate 14 and is connected to the turntable 16. And the connection between the threaded rod 17 and the bottom plate 14 is a threaded connection. And the threaded rod 17, the turntable 16 and the bottom plate 14 form a threaded lifting structure. Rotate the threaded rod 17 downward, so that the threaded rod 17 drives the clamping plate 15 to disengage from the bottom plate 14 through the turntable 16. In this way, there is a certain gap between the clamping plate 15 and the bottom plate 14. At this time, the gap between the clamping plate 15 and the bottom plate 14 is clamped into the edge of the working seat area, and then rotate the threaded rod 17 to make the clamping plate 15 approach the bottom plate 14, so that the machine body 13 can be stably fixed on the placement area.

[0025] Working principle: When using the power frequency withstand voltage detector with protection function for power equipment, first, there are two threaded rods 17 at the bottom of the machine body 13. During use, rotate the threaded rods 17 downward, so that the threaded rods 17 drive the clamping plates 15 to disengage from the bottom plate 14 through the turntables 16. In this way, there is a certain gap between the clamping plates 15 and the bottom plate 14. At this time, the gap between the clamping plates 15 and the bottom plate 14 is clamped into the edge of the working seat area, and then rotate the threaded rods 17 to make the clamping plates 15 approach the bottom plate 14, so that the machine body 13 can be stably fixed on the placement area, thus preventing the risk of the product falling from a high place due to shaking during use. The bolt 6 and the protective cover 1 of the product are snap-connected. In this way, after the protective cover 1 is opened, rotate the rotating rod 11 to make the bolt 6 snap into the inside of the protective cover 1, so that the protective cover 1 can be fixed in the open state through the rotating rod 11, thus preventing the protective cover 1 from accidentally closing and affecting the use of the equipment. In addition, docking blocks 4 are connected to both sides of the protective pad 5, and the docking blocks 4, the clamping blocks 3 and the card slots 2 are snap-connected. The protective pad 5 can be installed into the card slot 2 of the protective cover 1 through the docking blocks 4 and the clamping blocks 3. In this way, when the protective cover 1 is squeezed, it will not directly damage the machine body 13. This is the characteristic of the power frequency withstand voltage detector with protection function for power equipment.
