[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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 work should belong to the scope of protection of the present invention.

[0026] Example

[0027] like Figure 1 As shown, the present invention relates to a grounding cap for a grounding device, comprising a top sleeve 1, a bottom sleeve 2, a positioning screw 3, a positioning portion 4, a lifting eye screw 5 and a fixing screw 6.

[0028] The top sleeve 1 and the bottom sleeve 2 are integrally formed, both are three-dimensional cavity structures, the two are connected, and the size of the top sleeve 1 is larger than the size of the bottom sleeve 2. Specifically, the top sleeve 1 is a rectangular cavity structure or a cylindrical cavity structure, and the bottom sleeve 2 is a cylindrical cavity structure, which is used to connect the grounding rod, and its size matches the outer diameter of the connected grounding rod.

[0029] The top sleeve 1 has a ring screw hole on its wall for overlapping multiple grounding rods by installing a ring screw 5. The ring screw 5 passes through the top sleeve 1 wall through the ring screw hole. The ring screw 5 fixes and tightens the grounding wire terminal to achieve overlapping of multiple grounding rods. Figure 3 As shown, the eye screw 5 includes an eye structure 51 and a screw portion 52 . The eye structure 51 is fixed to one end of the screw portion 52 , and the screw portion 52 is provided with a spiral texture.

[0031] A plurality of positioning screw holes are provided on the other side of the wall of the bottom sleeve 2. The plurality of positioning screw holes are arranged in sequence from top to bottom at equal intervals and are arranged below the eye screw hole. The function is to install the positioning screws 3 and then serve as force-bearing points when the overlapping cap is used to move the grounding rod.

[0032] In this embodiment, as a preferred solution, a total of three positioning screws 3 are provided as force-absorbing points when the grounding rod is moved by using the overlapping cap. The positioning screws 3 are also screw structures with lifting ring structures, and the specific structure is the same as that of the lifting ring screws 5 in this embodiment.

[0033] A positioning portion 4 is provided at the bottom of the wall of the bottom sleeve 2. Specifically, the positioning portion 4 is provided at the central position of the bottom of the bottom sleeve 2 corresponding to the positioning screw 3. The positioning portion 4 is in the form of a positioning mark, such as a scratch, a scale, etc. The positioning portion 4 corresponds to the insertion position of the grounding rod. When installing with the grounding rod, according to the position of the positioning portion 4, guided by the positioning screw 3, the grounding rod is pushed into the bottom sleeve 2 and the top sleeve 1 in turn, and then the entire lap cap is pushed in, and the fixing screw 6 is tightened, so that the lap cap can be fixed on the grounding rod, and the grounding current flows to the grounding rod through the fixing screw 6.
