Description

Technical Field

[0001] The utility model relates to the technical field of electric power appliances, and more specifically to a puncture grounding wire clamp. Background Art

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc.

[0003] Some patent documents with puncture grounding wire clamps are disclosed in the prior art. The Chinese patent with application number CN202321572344.0 discloses a puncture grounding wire clamp, which is used to solve the technical problem mentioned in the background technology that when some puncture grounding wire clamps puncture wires with too large diameters, the grounding ring cannot abut against the connection between the puncture metal sheet on one side of the second upper shell and the puncture metal sheet on one side of the second lower shell, thereby failing to form a conductive closed loop, and the current cannot be led out to the grounding wire through the grounding ring. It includes a first upper shell and a first lower shell, the first upper shell and the first lower shell are both penetrated with a first metal sheet and a second metal sheet, the first metal sheet and the second metal sheet are rotatably connected, the second metal sheet in the first upper shell and the second metal sheet in the first lower shell correspond to each other up and down, and the side walls of the first upper shell and the first lower shell are penetrated with two second bolts connected by threads.

[0004] In the above patent, the upper and lower shells are directly fixed by bolts. After the bolts are exposed to the outside for a long time, the surface of the bolts is prone to rust, which makes it difficult to disassemble and affects the use of the grounding clamp. For this reason, we propose a piercing grounding clamp. Utility Model Content

The movement of the plug block makes the plug block no longer engage with the jack. At this time, the upper shell can be removed from the lower shell, thereby completing the disassembly of the lower shell and the upper shell. By placing the bidirectional screw rod in the installation groove, the problem of weathering and rusting caused by the bidirectional screw rod being exposed to the outside is prevented, and the convenience of using the lower shell and the upper shell in combination is optimized.

[0042] The first spike 10 and the second spike 20 cooperate to clamp the ground wire. The plug plate 12 is provided with a socket 13. The socket 13 is provided to engage with the plug block 17. The lower shell 1 and the upper shell 2 are installed by engaging with the socket 13 and the plug block 17. When the bidirectional screw rod 15 rotates forward, the two nuts 16 move inward at the same time. The movement of the nut 16 drives the plug block 17 to move inward. The movement of the plug block 17 makes the plug block 17 no longer engage with the socket 13. At this time, the upper shell 2 can be removed from the lower shell 1, thereby completing the disassembly of the lower shell 1 and the upper shell 2. By placing the bidirectional screw rod 15 in the mounting groove 3, the problem of the bidirectional screw rod 15 being exposed to the outside and causing weathering and rusting is prevented, thereby optimizing the convenience of the combined use of the lower shell 1 and the upper shell 2.

[0043] Specifically, the mounting mechanism includes a positioning plate 14, a bidirectional screw rod 15, a nut 16, an insert block 17 and a through hole 18. The positioning plate 14, the nut 16, the insert block 17 and the through hole 18 are each provided with two, the two positioning plates 14 are both fixedly connected in the mounting groove 3, the bidirectional screw rod 15 is rotatably connected in the two positioning plates 14, the two nuts 16 are both threadedly connected to the surface of the bidirectional screw rod 15, the two insert blocks 17 are respectively fixedly connected to the two nuts 16, the two through holes 18 are respectively opened at the side ends of the two insert blocks 17, and the bidirectional screw rod 15 movably passes through the two through holes 18.

[0044] In this embodiment, the positioning plate 14 is for facilitating the rotation of the bidirectional screw rod 15. The rotation of the turning handle 19 drives the bidirectional screw rod 15 to rotate. The rotation of the bidirectional screw rod 15 causes the two nuts 16 to move inward or outward on the surface of the bidirectional screw rod 15 at the same time. When the bidirectional screw rod 15 rotates forward, the two nuts 16 move inward at the same time, and the movement of the nuts 16 drives the plug block 17 to move inward. The movement of the plug block 17 makes the plug block 17 no longer engage with the socket 13. At this time, the upper shell 2 can be removed from the lower shell 1, thereby completing the disassembly of the lower shell 1 and the upper shell 2.

[0045] Specifically, a card slot 4 is provided on the upper shell 2 , and a card plate 5 is carded in the card slot 4 .

[0046] In this embodiment, the card slot 4 is provided to facilitate the placement of fingers into the installation slot 3 , and the card plate 5 is provided to facilitate sealing the card slot 4 . The card plate 5 is installed on the card slot 4 by means of a snap connection.

[0047] Specifically, a handle 19 is fixedly connected to the surface of the bidirectional screw rod 15 . The handle 19 is located between the two positioning plates 14 , and the position of the handle 19 corresponds to the position of the card slot 4 .

[0048] In this embodiment, the handle 19 is pushed by fingers to rotate, and the rotation of the handle 19 drives the bidirectional screw rod 15 to rotate.

[0052] In this embodiment, the threaded hole 7 is provided to facilitate the threaded connection of the screw 8. The threaded cooperation between the threaded hole 7 and the screw 8 facilitates the movement of the clamping plate 9, thereby adjusting the position of the clamping plate 9 to facilitate clamping the ground wire.

[0053] Specifically, the two nuts 16 are located outside the two positioning plates 14 .

[0054] In this embodiment, the two nuts 16 are located outside the two positioning plates 14 .

[0055] Working principle: when the lower shell 1 and the upper shell 2 need to be disassembled, hold the handle 6, take the card plate 5 out of the card slot 4, and then push the turning handle 19 with your fingers to rotate. The rotation of the turning handle 19 drives the bidirectional screw rod 15 to rotate. The rotation of the bidirectional screw rod 15 makes the two nuts 16 move inward or outward on the surface of the bidirectional screw rod 15 at the same time. When the bidirectional screw rod 15 rotates forward, the two nuts 16 move inward at the same time, and the movement of the nut 16 drives the plug block 17 to move inward. The movement of the plug block 17 makes the plug block 17 no longer engage with the socket 13. At this time, the upper shell 2 can be taken out from the lower shell 1, thereby completing the disassembly of the lower shell 1 and the upper shell 2.
