[0020] Embodiment 1: A fixed base 2 is installed at the bottom of the protective cover 1, a second circuit sealing groove 13 is installed at the top of one side of the protective cover 1, a grounding terminal body 3 is installed inside the protective cover 1, a handle 11 is movably installed on the top of the grounding terminal body 3, a second sealing plate 8 is installed at the bottom of the outer side of the sealing cover 9, a first sealing plate 7 is installed at the top of the outer side of the protective cover 1, a plurality of bolts 10 are installed between the first sealing plate 7 and the second sealing plate 8, a first circuit sealing groove 12 is installed on one side of the sealing cover 9, the first circuit sealing groove 12 and the second circuit sealing groove 13 are respectively semicircular arc-shaped, and the first circuit sealing groove 12 and the second circuit sealing groove 13 are installed in coordination.

[0021] Specifically, Figure 1 and Figure 3 As shown, since a fixing base 2 is installed at the bottom of the protective cover 1, the protective cover 1 can be fixed to the position where the grounding terminal body 3 needs to be installed through the fixing base 2. After the protective cover 1 is installed, the grounding terminal body 3 can be inserted into the protective cover 1 through the top of the protective cover 1 to protect the grounding terminal body 3. Since a second line sealing groove 13 is installed on one side of the protective cover 1, the wire connected to the grounding terminal body 3 can be extended out of the protective cover 1 through the second line sealing groove 13. Then, by connecting the sealing cover 9 to the protective cover 1, the grounding terminal body 3 is completely sealed in the protective cover 1 and the sealing cover 9. When the protective cover 1 and the sealing cover 9 are sealed and connected, due to the sealing A first circuit sealing groove 12 is installed on one side of the cover 9. The bottom of the first circuit sealing groove 12 is aligned with the top of the second circuit sealing groove 13, and then the first sealing plate 7 is aligned with the second sealing plate 8. Then, the first sealing plate 7 and the second sealing plate 8 are fixed by bolts 10. The first circuit sealing groove 12 and the second circuit sealing groove 13 can be used to seal and protect the extension of the wire. Since a handle 11 is installed on the top of the grounding terminal body 3, the handle 11 can be used to facilitate the operator to pull the grounding terminal body 3 out of the inside of the protective cover 1 without causing damage to the grounding terminal body 3. Through this device, the grounding terminal body 3 can be isolated from the outside during use, thereby preventing the grounding terminal body 3 from being corroded during use and improving the service life of the grounding terminal body 3.

[0022] Embodiment 2: A threaded groove 6 is respectively installed on both sides of the protective cover 1, and a threaded rod 5 is movably installed inside the two threaded grooves 6, the threaded rod 5 is connected to the threaded groove 6 by threaded engagement, and a knob 14 is installed at one end of the threaded rod 5, one end of the two threaded rods 5 extends into the protective cover 1, and a rotating connecting seat 17 is respectively installed at one end of the two threaded rods 5, an arc-shaped splint 16 is installed on one side of the rotating connecting seat 17, and a plurality of rubber anti-slip pads 18 are equidistantly installed on one side of the arc-shaped splint 16, a supporting slide rod 15 is installed on the outer side of the arc-shaped splint 16, and the supporting slide rod 15 is slidably installed inside the protective cover 1.

[0023] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since a threaded rod 5 is movably installed inside the two sides of the protective cover 1, and a knob 14 is installed at one end of the threaded rod 5, the threaded rod 5 can be driven to rotate by rotating the knob 14. When the threaded rod 5 rotates, one end of the threaded rod 5 will be extended and retracted inside the protective cover 1. Since one end of the threaded rod 5 is connected to an arc-shaped clamping plate 16 through a rotating connecting seat 17, and one side of the arc-shaped clamping plate 16 is connected to the inside of the protective cover 1 through a supporting sliding rod 15, the rotation of the threaded rod 5 can drive the arc-shaped clamping plate 16 to be extended and retracted in the protective cover 1. By controlling the extension and retraction of the two arc-shaped clamping plates 16, the two sides of the grounding terminal body 3 installed inside the protective cover 1 can be clamped, thereby ensuring the stability of the grounding terminal body 3 installed inside the protective cover 1, and avoiding collision between the grounding terminal body 3 and the inner wall of the protective cover 1, avoiding damage to the grounding terminal body 3, and further improving the service life of the grounding terminal body 3.

[0024] Working principle: When in use, since the bottom of the protective cover 1 is equipped with a fixed base 2, the protective cover 1 can be fixed to the position where the grounding terminal body 3 needs to be installed through the fixed base 2. After the protective cover 1 is installed, the grounding terminal body 3 can be inserted into the protective cover 1 through the top of the protective cover 1 to fix the base 2. Then, the sealing cover 9 is connected to the protective cover 1. When the protective cover 1 and the sealing cover 9 are sealed, since one side of the sealing cover 9 is equipped with a first circuit sealing groove 12, the bottom of the first circuit sealing groove 12 is aligned with the top of the second circuit sealing groove 13, and then the first sealing plate 7 is aligned with the second sealing plate 8. Then The first sealing plate 7 and the second sealing plate 8 can be fixed by bolts 10, and the first line sealing groove 12 and the second line sealing groove 13 can be used to seal and protect the extension of the wires. Then, the rotation of the threaded rod 5 can drive the arc clamping plate 16 to expand and contract in the protective cover 1. By controlling the expansion and contraction of the two arc clamping plates 16, the two sides of the grounding terminal body 3 installed inside the protective cover 1 can be clamped, thereby ensuring the stability of the grounding terminal body 3 installed inside the protective cover 1, and avoiding collision between the grounding terminal body 3 and the inner wall of the protective cover 1, avoiding damage to the grounding terminal body 3, and further improving the service life of the grounding terminal body 3.
