Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1 and Figure 2The utility model provides an embodiment: a grounding wire hanging structure with an anti-mistaken disassembly function, including a fixed block 1, the outer walls of both sides of the fixed block 1 are fixedly connected to a hollow block 2, the interior of the hollow block 2 is rotatably connected to a worm 3, the left outer wall of the worm 3 is fixedly connected to a handle 4, the tooth end of the worm 3 is meshed with a worm wheel 5, the interior of the worm wheel 5 is fixedly connected to a connecting rod 6, both ends of the connecting rod 6 are rotatably connected to the inner wall of the hollow block 2, the rear outer wall of the connecting rod 6 is fixedly connected to a gear 7, the tooth end of the gear 7 meshes with the inner wall of the hollow block 2, and the outer wall of the rear side of the connecting rod 6 is fixedly connected to the gear 7. The rack 8 is connected to the hollow block 2, and the outer wall of the rack 8 is slidably connected to the inner wall of the hollow block 2. The rear outer wall of the rack 8 is fixedly connected to an L-shaped plate 9. A limiting groove 10 is provided inside the fixed block 1, and the outer wall of the L-shaped plate 9 is slidably connected to the inner wall of the limiting groove 10. A limiting component is provided on the left outer wall of the rack 8, and the limiting component is used to prevent the rack 8 from deflecting when sliding; the limiting component includes a slide rail 11, the right outer wall of the slide rail 11 is fixedly connected to the left outer wall of the rack 8, and the outer wall of the slide rail 11 is slidably connected to the inner wall of the hollow block 2;

[0027] Specifically, the interior of the hollow block 2 supports the rotation of the worm 3, and the handle 4 facilitates the rotation of the worm 3 to transmit the worm wheel 5. The inner wall of the hollow block 2 supports the rotation of the connecting rod 6, and then supports the gear 7. The gear 7 transmits the rack 8 through the connecting rod 6, and then drives the L-shaped plate 9 to move up and down, so as to achieve the effect of installation or disassembly of the fixed block 1. The limiting groove 10 has a range-limiting effect on the L-shaped plate 9. The slide rail 11 not only guides the rack 8, but also limits the rack 8. The fixed block 1 is usually installed tightly with the electrical equipment, which is inconvenient to operate the fixed block 1. Therefore, it is necessary to disassemble the hollow block 2 first.

[0028] Reference Figure 3 and Figure 4 The inner wall of the fixed block 1 is slidably connected to a special-shaped rod 12, and the outer wall of the special-shaped rod 12 is fixedly connected to a diamond plate 13; the outer wall of the diamond plate 13 is slidably connected to a transmission plate 14, and the outer wall of the transmission plate 14 is slidably connected to the inside of the fixed block 1, and the right outer wall of the transmission plate 14 is fixedly connected to a clamping block 16; the outer wall of the clamping block 16 is slidably connected to the inner wall of the fixed block 1, and the left outer wall of the clamping block 16 is fixedly connected to a spring 15, and the left outer wall of the spring 15 is fixedly connected to the inner wall of the fixed block 1;

[0029] Specifically, the diamond plate 13 is set to be inclined to facilitate the transmission of the transmission plate 14. The transmission plate 14 transmits the effect of the clamping block 16 through the movement of the diamond plate 13. The clamping block 16 is set to be arc-shaped to facilitate the effect of clamping or releasing the grounding wire. The inner wall of the fixed block 1 has the effect of limiting the offset of the sliding of the clamping block 16, and the spring 15 has the effect of limiting the range of the sliding of the clamping block 16.

[0030] Reference Figure 3 , the lower surface of the special-shaped rod 12 is fixedly connected to the limit rod 17, and the inner wall of the limit rod 17 is slidably connected to the L-shaped rod 18; the outer wall of the L-shaped rod 18 is slidably connected to the hollow column 19, and the outer wall of the hollow column 19 is fixedly connected to the lower surface of the fixed block 1; the left outer wall of the L-shaped rod 18 is fixedly connected to the disc 20, and the outer wall of the disc 20 is slidably connected to the inner wall of the hollow column 19; the right outer wall of the hollow column 19 is fixedly connected to the spring 21, and the right outer wall of the spring 21 is fixedly connected to the sliding sleeve 22; the outer wall of the sliding sleeve 22 is slidably connected to the inner wall of the hollow column 19, and the inner part of the sliding sleeve 22 is slidably connected to the outer wall of the L-shaped rod 18;

[0031] Specifically, the interior of the hollow column 19 supports and limits the displacement of the L-shaped rod 18, the inner wall of the hollow column 19 limits the displacement of the disc 20, the spring 21 limits the range of the disc 20, and the sleeve 22 prevents the spring 21 from deforming when the disc 20 rotates.

[0032] Working principle: When using this structure, place the fixed block 1 and the hollow block 2 at the installation port of the electrical equipment, and rotate the handle 4 to drive the worm 3 to rotate, thereby driving the worm wheel 5 and the connecting rod 6 to rotate, thereby achieving a transmission effect on the gear 7. The gear 7 drives the rack 8 to move upward through the connecting rod 6, so that the L-shaped plate 9 moves upward on the inner wall of the limiting groove 10. The L-shaped plate 9 moves upward at the installation port, thereby limiting the hollow block 2, achieving the effect of quickly installing the fixed block 1, and the sliding of the rack 8 by the slide rail 11 reaches the offset limit. When removing the ground wire, it is necessary to first push the L-shaped rod 18 to slide to the right inside the hollow column 19, drive the disc 20 to slide to the right to squeeze the spring 21, and rotate the L-shaped rod 18 downward. Under the action of the sliding sleeve 22, the spring 21 is prevented from being deformed and stuck. When the outer wall of the L-shaped rod 18 slides out of the inner wall of the limiting rod 17, the limiting rod 17 and the special-shaped rod 12 can be operated. Pulling the limiting rod 17 drives the special-shaped rod 12 and the diamond plate 13 to move downward. Under the action of the inner wall inclined surface of the transmission plate 14, the diamond plate 1 3 drives the transmission plate 14 to slide to the left, causing the clamping block 16 to slide to the left on the inner wall of the fixed block 1, squeezing the spring 15 to achieve the effect of removing the ground wire. After removal, the limit rod 17 is released, and the elastic force of the spring 15 drives the transmission plate 14 and the clamping block 16 to slide to the right, causing the diamond plate 13, the special-shaped rod 12 and the limit rod 17 to move upward. When the limit rod 17 moves to the appropriate position, the L-shaped rod 18 is pulled, and the L-shaped rod 18 is pushed to slide to the left under the action of the spring 21, and slides into the inner wall of the limit rod 17 to limit it. , achieving the effect of locking the clamping block 16. During use, this structure not only allows for quick installation and removal of the fixing block 1, thereby enhancing the convenience of operation when performing daily maintenance, fault repair or component replacement on electrical equipment, but also has the function of releasing the bottom of the limit rod 17 first before operating the special-shaped rod 12. The cooperation between the limit rod 17 and the special-shaped rod 12 achieves the effect of controlling the clamping block 16 to be closed or opened, thereby avoiding the effect of personnel directly operating the limit rod 17 to remove the grounding wire, thereby ensuring personal safety.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
