[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A safety lightning protection grounding clamp includes:

[0026] The main body includes an upper pressure plate 1, a lower pressure plate 11 mounted on the surface of the upper pressure plate 1, and abutments 12 fixedly connected to the surfaces of the upper pressure plate 1 and the lower pressure plate 11. A rod 13 is inserted into the surfaces of the upper pressure plate 1 and the lower pressure plate 11, and a nut 14 is threadedly connected to the surface of the rod 13. When using the lightning protection grounding clamp, the rod 13 is first sleeved on the surface of the grounding rod and inserted into the upper pressure plate 1, so that the upper pressure plate 1 and the rod 13 abut against the grounding rod. Then, the grounding wire is placed inside the rod 13. After that, the lower pressure plate 11 is sleeved on the rod 13 and the two are inserted. Finally, the nut 14 is threadedly connected to the rod 13 and, after tightening, abuts against the surface of the lower pressure plate 11, so that the two sets of abutments 12 abut against the grounding wire, thereby completing the clamping effect of the grounding rod and the grounding wire. The grounding rod and the grounding wire are existing ones that can conduct the current from the electrical equipment to the ground.

[0027] The limiting mechanism includes a connecting plate 2, which is fixedly connected to the surface of the upper pressure plate 1. A fixing rod 21 is fixedly connected to the surface of the lower pressure plate 11. A movable plate 22 is installed on the surface of the lower pressure plate 11. A rotating groove 23 and a slot 26 are provided on the surface of the fixing rod 21. A rotating rod 24 is fixedly connected to the surface of the movable plate 22. A torsion spring 25 is sleeved on the surface of the rotating rod 24. Under the action of the connecting plate 2, the installation of the movable plate 22 can be limited. Under the clamping of the two, the range of motion of the lower pressure plate 11 on the insertion rod 13 can be limited to prevent the operator from being blocked by the movement of the lower pressure plate 11 when tightening the nut 14.

[0028] Furthermore, there are two sets of connecting plates 2 and fixing rods 21. The two sets of connecting plates 2 are installed on both sides of the upper pressure plate 1, and the two sets of fixing rods 21 are installed on both sides of the lower pressure plate 11. Each set of fixing rods 21 consists of two rods. Each set of fixing rods 21 is located on both sides of the movable plate 22. Under the action of the fixing rods 21, the movable plate 22 can be installed and moved on the surface of the lower pressure plate 11.

[0029] Furthermore, one end of the movable plate 22 is movably connected to the surface of the fixed rod 21, and the other end of the movable plate 22 is engaged with the surface of the connecting plate 2. The diameter of the rotating groove 23 is the same as the diameter of the rotating rod 24. Two sets of rotating rods 24 and torsion springs 25 are provided. The two sets of rotating rods 24 and torsion springs 25 are installed on both sides of the movable plate 22. The connection effect between the connecting plate 2 and the fixed rod 21 can be achieved through the movable plate 22, thereby achieving the connection effect between the upper pressure plate 1 and the lower pressure plate 11. With the connection of the rotating groove 23 and the rotating rod 24, the connecting plate 2 can rotate around the rotating rod 24 as the center.

[0030] Furthermore, the rotating rod 24 is rotatably connected to the surface of the rotating groove 23, and the two ends of the torsion spring 25 are engaged with the surface of the slot 26. There are two sets of slots 26, one set of slots 26 is opened on the surface of the fixed rod 21, and the other set of slots 26 is opened on the surface of the movable plate 22. The slots 26 can be used to limit the installation of the torsion spring 25. Under the action of the torsion spring 25, a torsional force can be applied to the surface of the movable plate 22 and make it always tend to rotate towards the downward pressing plate 11.

[0031] Furthermore, the surface of the abutment 12 is provided with a connecting mechanism, which includes a connecting rod 3. The connecting rod 3 is fixedly connected to the surface of the upper pressure plate 1 and the lower pressure plate 11. A connecting groove 31 and a insertion hole 33 are provided on one side of the abutment 12, and a storage groove 34 is provided on the other side of the abutment 12. Threaded grooves 32 are provided on the surface of the upper pressure plate 1 and the lower pressure plate 11. Screws 35 are installed on the surface of the abutment 12. The surfaces of the upper pressure plate 1 and the lower pressure plate 11 are both provided with connecting rods 3 and threaded grooves 32. Through the arrangement of the two, the abutment 12 can be installed on the surface of the upper pressure plate 1 and the lower pressure plate 11 respectively.

[0032] Furthermore, two sets of connecting rods 3 and connecting grooves 31 are provided. The two sets of connecting rods 3 and connecting grooves 31 are located on both sides of the abutment block 12. The connecting rods 3 are inserted into the surface of the connecting grooves 31. The cross-section of the connecting rods 3 and connecting grooves 31 is "L" shaped. The length of the connecting rods 3 is the same as the length of the connecting grooves 31. The lengths of the connecting rods 3, connecting grooves 31 and abutment block 12 are all the same. The two sets of connecting rods 3 and the two sets of connecting grooves 31 are arranged opposite to each other. With the connection of the connecting rods 3 and connecting grooves 31, the abutment block 12 can slide along the direction of the connecting rods 3 and achieve the limitation of the direction perpendicular to the connecting rods 3.

[0033] Furthermore, the diameter of the insertion hole 33 is smaller than the diameter of the storage groove 34. The screw 35 is inserted into the surface of the insertion hole 33. One end of the screw 35 is threaded into the surface of the threaded groove 32, and the other end of the screw 35 is abutted into the surface of the storage groove 34. The screw 35 can be installed by the threaded groove 32, the insertion hole 33, and the storage groove 34. The storage groove 34 ensures that the screw 35 will not protrude from the inside of the abutment block 12 during installation, thereby avoiding the situation where the abutment block 12 is obstructed when clamping the grounding wire.

[0034] Working principle: When the lightning protection grounding clamp is connected to the grounding rod and grounding wire and the nut 14 is installed, the movable plates 22 on both sides of the lower pressure plate 11 are first pried open so that they rotate outward around the rotating rod 24 connected to them, so that the rotating rod 24 rotates on the surface of the rotating groove 23. The torsion spring 25 is in a torsion state. At this time, the lower pressure plate 11 is moved on the surface of the insertion rod 13 and the movable plate 22 is moved away from the fixed rod 21 and closer to the connecting plate 2. Then, the movable plates 22 on both sides are released in sequence, so that the movable plate 22 rotates again under the torsion force applied by the torsion spring 25 and is locked on the surface of the connecting plate 2, so as to complete the movement restriction of the lower pressure plate 11 on the insertion rod 13, thereby reducing the obstruction of the nut 14 on the insertion rod 13.

[0035] When using the lightning protection grounding clamp and replacing the abutment 12, first align the connecting grooves 31 on both sides of the abutment 12 with the connecting rod 3 and insert them into the grooves, so that the two sets of abutments 12 slide on the surfaces of the upper pressure plate 1 and the lower pressure plate 11 respectively. When the insertion hole 33 and the threaded groove 32 are aligned, insert the screw 35 into the insertion hole 33 and turn it with a Phillips screwdriver, so that the screw 35 moves on the surface of the threaded groove 32 through the thread and is pressed against the storage groove 34 after tightening, thus completing the installation and replacement of the abutment 12.
