[0002] Lightning protection grounding is divided into two concepts: lightning protection, which prevents damage caused by lightning strikes; and static grounding, which prevents harmful static electricity. A grounding wire is a safety device used to temporarily disconnect and ground equipment that has been powered off. Its function is to prevent the harm of induced voltage from sudden power surges and nearby high-voltage live equipment when power is turned off for maintenance or other work. It also discharges residual charge from the powered-off equipment. A grounding wire consists of three main parts: a ground terminal, a conductor, and a wire clamp.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments, not all of the embodiments. Based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.
[0022] Example 1:
[0023] See also Figs. 1-3 A lightning protection grounding wire clamp that is easy to use includes a connecting shaft 1, a first clamping frame 2 is fixedly installed on the upper end of the connecting shaft 1, threaded fasteners 3 are threadedly installed on the two side surfaces of the first clamping frame 2, a second clamping frame 4 is threadedly installed on the upper part of the threaded fastener 3, a connecting plate 5 is fixedly installed on the upper surface of the second clamping frame 4, a threaded cylinder 7 is opened on the surface of the connecting plate 5, a threaded rod 8 is threadedly installed on the inner wall of the threaded cylinder 7, a clamping plate 9 is rotatably installed on the lower end of the threaded rod 8, and limiting plates 10 are fixedly installed on both sides of the upper surface of the clamping plate 9. Gaskets 11 are provided on the lower sides of the first clamping frame 2.
[0024] Preferably, a placement groove 6 is opened inside the second clamping frame 4 , the clamping plate 9 can be set in the placement groove 6 , and the outer side of the limiting plate 10 is slidably connected to the surface of the connecting plate 5 .
[0025] Specifically, the first clamping frame 2 and the second clamping frame 4 can clamp and fix the line through the threaded fastener 3. When the first clamping frame 2 and the second clamping frame 4 are clamped, the gasket 11 increases its stability to avoid gaps. When encountering a relatively small line, the threaded rod 8 is rotated to bring the card plate 9 downward. The card plate 9 will move out of the placement slot 6, and the smaller card plate 9 can fix the smaller line.
[0026] Preferably, the mutually adjacent clamping surfaces of the first clamping frame 2 and the second clamping frame 4 are both provided with anti-slip rubber particles.
[0027] Specifically, by setting the anti-slip rubber particles, the friction of the clamping can be increased, making the fixation more stable, while also protecting the line.
[0028] Working principle: When fixing the wire, place the wire into the first clamping frame 2 and the second clamping frame 4, and then install the threaded fastener 3. The first clamping frame 2 and the second clamping frame 4 fix the wire, and the non-slip rubber particles on the clamping surface can protect the fixed wire. If a smaller wire is encountered and the first clamping frame 2 and the second clamping frame 4 cannot fix it, you can manually rotate the threaded rod 8, the threaded rod 8 will move downward, and the threaded rod 8 will carry the card plate 9 downward. The card plate 9 will move out of the placement slot 6, and the limiting plate 10 will also move downward to limit the movement of the card plate 9. The card plate 9 can fix the smaller wire, so that the clamping range of the wire clamp can be easily adjusted, and it can clamp smaller wires, thereby improving the practicality of the wire clamp.
[0029] Example 2:
[0030] See also Figs. 1-3 The lower end of the connecting shaft 1 is rotatably installed with a connecting shaft 12, and the upper part of the connecting shaft 12 is fixedly installed with a limiting tooth 19. A slide groove 13 is provided on the surface of the connecting shaft 1, and a fixing rod 14 is fixedly installed on the inner wall of the slide groove 13. A connecting block 15 is slidably installed on the outer side of the fixed rod 14, and a movable gear sleeve 17 is fixedly installed on the outer side of the connecting block 15. The movable gear sleeve 17 is engaged with the limiting tooth 19.
[0031] Specifically, the movable gear sleeve 17 is slidably connected to the inner wall of the slide groove 13 through the connecting block 15. The movable gear sleeve 17 can only slide up and down on the surface of the connecting shaft 1. After the movable gear sleeve 17 engages with the limiting tooth 19, the rotation of the connecting shaft 1 can be limited.
[0032] Preferably, the outer side of the connecting block 15 is slidably connected to the inner wall of the slide groove 13, a spring 18 is wound around the outer side of the fixing rod 14, the lower end of the spring 18 is connected to the surface of the connecting block 15, and a handle 16 is fixedly installed on the outer side of the connecting block 15.
[0033] Specifically, pulling the handle 16 upward can move the connecting block 15 upward, and the connecting block 15 will move upward with the movable gear sleeve 17. After the movable gear sleeve 17 leaves the limiting tooth 19, the connecting shaft 1 is free from restriction, and the connecting shaft 1 can be rotated, and the connecting shaft 1 will rotate with the wire clamp.
[0034] Working principle: When adjusting the angle of the wire clamp, pull the handle 16 upwards, the handle 16 will move upwards with the connecting block 15 and the movable gear sleeve 17, and the connecting block 15 will move along the fixed rod 14 and squeeze the spring 18. As the movable gear sleeve 17 disengages from the limiting tooth 19, the connecting shaft 1 can be rotated, and the connecting shaft 1 will rotate with the wire clamp above, so that the angle of the wire clamp can be adjusted. After adjusting the position, loosen the handle 16, and under the elastic force of the spring 18, the movable gear sleeve 17 will be stuck in the limiting tooth 19, which can limit the connecting shaft 1, thereby achieving the purpose of conveniently adjusting the angle of the wire clamp and facilitating construction operations.
[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, the scope of which is defined by the appended claims and their equivalents.
