[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figure 1 As shown, the electrical grounding structure provided in this embodiment includes a protective box 1 and a positioning box 2. An insulating sleeve 3 is fixedly installed on the surface of the protective box 1. An installation sleeve 4 is fixedly installed on the inner surface of the insulating sleeve 3. A retaining tooth 5 is fixedly installed on the surface of the installation sleeve 4. A fixing bolt 6 is threadedly connected to the surface of the insulating sleeve 3.

[0021] like Figure 2 As shown, the protective box 1 has T-shaped blocks 7 on both sides. The T-shaped block 7 includes a first protrusion 24 whose side is flush with the top of the box and fixed to the side of the box, and a second protrusion 25 disposed on both sides of the first protrusion 24 in the height direction.

[0022] The positioning box 2 is used to fix it on the mounting base surface, and the side of the positioning box 2 opposite to the protective box 1 is provided with a T-shaped groove 16 for nesting and assembly with the T-shaped block 7. The T-shaped groove 16 includes a pair of baffles perpendicular to the mounting base surface. The inner side of the two baffles is provided with a limiting groove that cooperates with the second protrusion 25 for limiting. The side of the positioning box 2 located between the two baffles is provided with a fixing groove 17.

[0023] like Figure 3 As shown, the first protrusion 24 has an assembly gap along the height direction of the box body. The assembly gap is provided with a first locking hole 26 that is perpendicular to the side of the box body and faces inward. Below the first protrusion 24, on the side of the box body, is a second locking hole 27 that is perpendicular to the side of the box body and faces inward. The first locking hole 26 and the second locking hole 27 are not on the same vertical line.

[0024] like Figure 4 , Figure 5 as well as Figure 6As shown, the connecting mechanism includes a push plate 14 and a connecting frame 11 vertically fixed on the push plate 14. The connecting frame 11 includes a connecting rod nested in the assembly gap and a fixing block 9 fixed on the connecting rod. The connecting rod is provided with a first positioning rod 10 passing through the first locking hole 26. The fixing block is provided with a second positioning rod (13) passing through the second locking hole 27. The fixing block 9 is embedded in the fixing groove 17 for positioning.

[0025] like Figure 7 and Figure 8 As shown, the positioning box 2 also includes a fixed cone 19 with its port located inside the positioning box 2, and a fixed screw 18 that enters the positioning box 2 from the top and is threadedly connected to the port of the fixed cone 19. The circumferential surface of the fixed cone 19 is provided with a telescopic cone head 21, which is pushed out by rotating and moving downward through the fixed screw 18.

[0026] More specifically, the protective box 1 has a first positioning rod 10 and a first spring 8 nested in the nested holes on both sides of the box body. The other end of the first positioning rod 10 and the first spring 8 is fixedly installed with a fixing block 9. A connecting frame 11 is fixedly installed on the surface of the fixing block 9. A second spring 12 and a second positioning rod 13 are fixedly installed on the surface of the connecting frame 11. A push plate 14 is fixedly installed on the top of the connecting frame 11. A handle 15 is fixedly installed on the surface of the push plate 14. A T-slot 16 is opened on the surface of the positioning box 2. A fixing groove 17 is opened on the surface of the T-slot 16. The T-block 7 and the T-slot 16 are slidably connected. The fixing block 9 and the fixing groove 17 are slidably connected. Through the precise cooperation between the T-block 7 and the T-slot 16, the stability between the protective box 1 and the positioning box 2 is ensured. Through the tight fit between the fixing block 9 and the fixing groove 17, the overall structural rigidity is enhanced, and it is also convenient to quickly replace damaged parts. The first positioning rod 10 and the second positioning rod 13 are slidably connected to the nesting hole of the outer shell on the side end of the protective box 1. The arrangement of the first positioning rod 10 and the second positioning rod 13 can make the movement of the fixing block 9 smoother when the push plate 14 is pushed, thus extending the service life. The elasticity of the first spring 8 and the second spring 12 can form a stable pressure between the fixing block 9 and the fixing groove 17, ensuring a firm connection and facilitating the disassembly and replacement of parts. The push plate 14 is slidably connected to the protective box 1 and the positioning box 2. The push plate 14 is set above the protective box 1 and the positioning box 2, which can effectively protect the connecting parts between the protective box 1 and the positioning box 2 and prevent the adverse effects of external environmental factors on the internal structure.

[0027] In addition, a fixing screw 18 is threadedly connected to the surface of the positioning box 2, and a fixing cone 19 is fixedly installed inside the positioning box 2. A reserved groove 20 is opened on the surface of the fixing cone 19, and a cone head 21 is slidably connected to the surface of the reserved groove 20. A limit ring 22 is fixedly installed on the surface of the cone head 21, and a hemispherical guide block 23 is fixedly installed on the surface of the limit ring 22. When the fixing screw 18 moves downward inside the fixing cone 19, the front end of the fixing screw 18 will push the hemispherical guide block 23 forward on the surface of the reserved groove 20, thereby pushing the cone head 21 out of the fixing cone and making close contact with the ground, ensuring the stability of the device. The fixing screw 18 and the fixing cone 19 are threadedly connected, and the cone head 21 and the reserved groove 20 are slidably connected. By adjusting the thread between the fixing screw 18 and the fixing cone 19, the cone head 21 can be moved precisely within the reserved groove 20.

[0028] In practical work, the worker can insert the fixing cone 19 into the ground and use a tool to rotate the fixing screw 18. As the fixing screw 18 rotates, it will slowly move downward inside the fixing cone 19. As the fixing screw 18 gradually moves downward, the hemispherical guide block 23 is pushed, causing the cone head 21 to move precisely outward inside the reserved groove 20. The contact area between the cone head 21 and the ground increases, forming a firm anchor and preventing the device from shaking. This firmly fixes the protective box 1 and the positioning box 2 to the ground. Finally, the grounding wire is placed inside the insulating sleeve 3, and then the fixing bolt 6 is rotated with a tool to make the grounding wire and the mounting sleeve 4... The teeth 5 on the upper part are tightly engaged to ensure a stable connection of the grounding wire, prevent loosening, and improve the safety and reliability of the overall device. When it is necessary to replace or disassemble the parts, the handle 15 can be pulled to move the push plate 14 toward the protective box. At the same time, the connecting frame 11 will drive the fixing block 9 to disengage from the fixing groove 17. The first positioning rod 10 and the second positioning rod 13 can provide stable guidance and support for the connecting frame 11 and the fixing block 9 when the push plate 14 is pushed. Finally, the T-shaped block 7 can be moved upward and separated from the T-shaped groove 16, and the protective box 1 can be slid out smoothly. The disassembly process is simple and efficient, ensuring that maintenance work is carried out smoothly.
