Description

Technical Field

[0001] The utility model relates to the technical field of grounding bodies, in particular to a composite graphite grounding body. Background Art

[0002] At present, the grounding body is a conductor that is in close contact with the earth's soil and provides an electrical connection with the earth, safely dissipating lightning energy and allowing it to be discharged into the earth. Most of the existing grounding bodies are graphite grounding bodies, which include a graphite core and an inorganic or synthetic fiber protective layer wrapped around the graphite core. However, the overall performance of this type of graphite grounding body is poor, mainly in terms of mechanical strength.

[0003] For example, a composite graphite grounding body disclosed in publication number CN220253499U uses a graphene layer and a stainless steel reinforcement layer to sequentially strengthen the protection of the graphite rod from the inside to the outside, making the structure more stable and having good conductive properties. A shock-absorbing buffer layer is then used to reduce shock, reduce impact force, and improve the stability of the internal structure.

[0004] However, the practicality of this protective structure is poor when in use. Although the protective structure reduces shock through the shock-absorbing buffer layer to reduce the impact force, it does not protect the rod core inside the graphite rod body. Therefore, when it is squeezed or collided, the rod core may be damaged. In view of this, we propose a composite graphite grounding body. Utility Model Content

[0026] In one embodiment of the utility model, a protective structure 3 is provided to protect the rod core 6 inside the graphite rod body 1, and a buffer layer 7 is used to protect the inside of the graphite rod body 1, thereby reducing the impact force, improving the stability of the internal structure, and preventing the internal structure from being damaged due to vibration. The protective layer 9 is used to provide good protection for the internal structure. When the graphite rod body 1 is impacted or squeezed, it moves inward through the inner wall of the graphite rod body 1. At this time, the four groups of protective plates 37 always fix and support the rod core 6, and the protective plates 37 squeeze the T-shaped support rod 36 and the buffer spring 35 inward, so that the buffer spring 35 is compressed to generate a rebound force, thereby preventing the inside of the graphite rod body 1 from being damaged, and improving the practicality of the device.

After installation and use, for subsequent disassembly, the moving rod 41 can be pushed again to drive the slider 49 to move to the other side of the limit rod 43, and then the moving rod 41 can be pulled outward to drive the slider 49 to move sideways, so that the limit rod 43 squeezes the slider 49 on the moving rod 41 and slides sideways to finally fit with the limit block 42, and finally the limit rod 43 is moved sideways through the slider 49 to release the limit block 42, and finally the moving rod 41 is released, so that the support frame 33 can be disassembled and used.

[0028] During operation, the user can open the conductive tip 5 by rotating it, and then install the four sets of support frames 33. At this time, the limit block 42 at the lower end of the support frame 33 is connected to the inside of the connecting tube 32, and the limit block 42 is used to squeeze the limit rod 43, so that the limit rod 43 moves to both sides to release the limit block 42, and at this time the limit plate 44 will squeeze the first spring 46, and finally the limit block 42 moves to the other side of the limit rod 43, so that the moving rod 41 is clamped in the inside of the connecting tube 32, thereby completing the limit of the support frame 33, and then the conductive tip 5 is closed for use. At this time, the buffer layer 7 is used To protect the inside of the graphite rod 1, reduce the impact force, improve the stability of the internal structure, avoid damage to the internal structure due to vibration, and use the protective layer 9 to provide good protection for the internal structure.
