DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the utility model and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0025] Embodiment:

[0026] With reference to Figures 1-4, a grounding end of a grounding device includes a grounding rod 1, a pointed tip is provided at the bottom of the grounding rod 1, so that it can more easily penetrate the soil or other grounding media, increase the contact area between the grounding rod 1 and the ground, and thus ensure the grounding effect, a placing plate 2 is fixedly connected to the top of the grounding rod 1, and a twisting block 3 is also installed on the placing plate 2, and the twisting block 3 is installed in the middle position of the grounding rod 1, and a first thread groove 101 is also provided on the outer wall of the grounding rod 1, and then the mounting plate 4 is threadedly connected to the first thread groove 101, and a limiting hole 5 is also provided on the mounting plate 4, and a positioning rod 6 is slidably connected in the limiting hole 5. Six groups of limiting holes 5 arranged in a circle are used in the device, and a positioning rod 6 is provided on each group of limiting holes 5, and a pointed tip is also provided at the bottom of the positioning rod 6 for penetrating the soil or other grounding media.

[0027] In addition, refer to Figure 3 A groove 401 is also provided on the mounting plate 4, and the groove 401 has the same cross-sectional diameter as the placement plate 2, so that the mounting plate 4 can be rotated to make its groove 401 collide with the bottom of the placement plate 2. By extending the placement plate 2 into the groove 401, the placement plate 2 and the groove 401 can be more firmly connected, increasing the contact area of ​​the placement plate 2, reducing the possibility of shaking or loosening of the placement plate 2, and thus improving the stability of the grounding rod 1.

[0028] The principle is as follows: when the grounding rod 1 needs to be fixed, the positioning rod 6 in the limiting hole 5 can be taken out first, and then the mounting plate 4 can be tightened so that the placement plate 2 and the groove 401 are abutted, and then the grounding rod 1 is embedded in the soil or other grounding medium, and then the positioning rod 6 is placed in the limiting hole 5 for embedded installation, and a limiting block 601 is also installed on the top of the positioning rod 6. During installation, the limiting block 601 is fit with the inner wall of the limiting hole 5, so that the limiting hole 5 can fix the positioning rod 6 to achieve a limiting effect. At the same time, the surrounding area of ​​the placement plate 2 can be fixed so that it can form a stable support structure, which increases the stability and anti-tilting ability of the grounding rod 1, reduces the displacement or tilt of the grounding rod 1 due to external forces such as high and low temperature or accidental contact, and improves the grounding effect. At the same time, the use of multiple sets of positioning rods 6 and the grounding rod 1 can also reduce the grounding resistance, thereby improving the performance of the grounding device.

[0029] It needs to be explained that the torsion block 3 installed on the top of the placing plate 2 can be rotated by using a wrench or a twisting device, so that the grounding rod 1 can be more tightly connected with the mounting disc 4 together. A second threaded groove 202 is formed on the outer wall of the placing plate 2, and then the protective cover 7 is threadedly connected on the second threaded groove 202. The protective cover 7 can be made of insulating materials, such as silica gel or rubber. The conductive plate 201 is arranged on the placing plate 2 for connecting the conductive wire. The through hole is formed on the protective cover 7 for mounting the conductive wire. The warning icon 701 is arranged on the protective cover 7 for warning people, reducing the number of touching, and making the maintenance of the grounding rod 1 more convenient, effectively avoiding accidental touching of the grounding rod 1, reducing the risk of electric shock and injury, and improving the safety of the grounding system.

[0030] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
