Description

Technical Field

[0001] This utility model relates to the field of grounding wire connection technology, specifically a grounding wire connection tool. Background Technology

[0002] A grounding wire is a protective measure used for electrical equipment. Its function is to connect the metal casing of the equipment to the ground so that current can be conducted to the ground in the event of a equipment failure, thereby protecting the safety of personnel and equipment. Grounding wires are usually made of copper or aluminum wire, and their length and diameter are determined according to the size of the equipment and the current required.

[0003] A search of existing technology reveals that publication number CN116759867A discloses a convenient grounding wire mounting tool. It includes a fixed cylinder with two transverse grooves on its left side, and a rotating shaft rotatably mounted inside the fixed cylinder. A crossbar is fixedly connected to the left end of the rotating shaft, and a rotating cylinder is movably sleeved on the outside of the fixed cylinder. An operating clamp has a threaded hole on its right side, with a screw threaded into the hole. A mounting plate is rotatably connected to the left end of the screw, and two clamps are fixedly mounted on the left side of the mounting plate. A crossbar is slidably connected to the right end of the screw, within which the crossbar is slidably connected. An extension cylinder is positioned between the fixed cylinder and the operating clamp, with two connecting rods fixedly connected to its right side. The two connecting rods are slidably connected to corresponding transverse grooves, and a connector is fixedly connected to the left end of the outer side of the extension cylinder. The operating clamp is fixedly connected to the left side of the connector.

[0004] The comparison document shows that the use of a cross bar, screw, fixing clamp, and operating pliers makes it convenient and efficient to fix the grounding wire to the conductor remotely; however, it cannot be extended to adapt to different construction environments. Utility Model Content

[0012] Compared with existing technologies, the advantages of this utility model are: it allows for adjustment of the lifting rod's length to adapt to different construction environments. When the fixing hook cannot reach the desired attachment point, the lifting rod is pulled upwards. The locking teeth on the lifting rod engage with the locking block, causing the block to rotate and pushing the lifting rod upwards. After pushing the block, the block resets, securing the locking teeth and preventing the lifting rod from falling back. To reset the lifting rod, pull the ring; the ring, through the pull rope, rotates the locking block, removing the obstruction to the locking teeth and resetting the lifting rod. Once the grounding wire is engaged in the fixing hook, adjusting the rotating ring pushes the deflection ring upwards, securely connecting the grounding wire to the fixing hook.

[0019] 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.

[0020] Please see Figures 1-5 The embodiment provided by this utility model includes a handheld handle 1, which facilitates the operator's holding of the straw. A lifting rod 2 is movably connected inside the handheld handle 1, and the lifting rod 2 can extend outwards to increase its length. A fixing mechanism 3 is provided on the outer surface of the lifting rod 2, which can fix the length of the lifting rod 2. A rotating ring 4 is rotatably connected to the lower end of the handheld handle 1, and a linkage device 5 is provided at the upper end of the rotating ring 4. The rotating ring can adapt to the extension of the lifting rod 2 through the linkage device 5. A fastening mechanism 6 is provided at the upper end of the linkage device 5, and a fixing hook 7 is provided at the upper end of the fastening mechanism 6. One end of the fixing hook 7 has a hanging interface 8. The fastening mechanism 6 can connect and fix the grounding wire.

[0021] The linkage device 5 includes linkage vertical bars 9, which are evenly distributed on the upper surface of the rotating ring 4. A driven vertical bar 10 is provided between each of the linkage vertical bars 9. The upper end of each driven vertical bar 10 is rotatably connected to the fastening mechanism 6. A rotating groove is provided inside the hand handle 1, and the linkage device 5 is disposed within the rotating groove. When the lifting rod 2 moves upward, the driven vertical bars 10 move upward between the linkage vertical bars 9, maintaining the linkage.

[0022] The fastening mechanism 6 includes a threaded ring 11, with a lifting block 12 internally threadedly connected to the threaded ring 11. The lifting block 12 has a limiting groove 13 internally, and a limiting post 14 is provided within the limiting groove 13. The limiting post 14 is fixedly connected to the upper end of the lifting rod 2. A deflection ring 15 is provided at the upper end of the lifting block 12. When the threaded ring 11 rotates, it drives the lifting block 12 to move, enabling the deflection ring 15 to securely contact the grounding wire with the fixing hook 7.

[0023] The handheld lever 1 has multiple vertical rods 16 inside, and each vertical rod 16 has a rotating shaft inside. A locking block 18 is rotatably connected inside the rotating shaft. A vertical plate 19 is provided on one side of the locking block 18, and a pull rope 20 is provided at the lower end of the locking block 18.

[0024] The outer surface of the lifting rod 2 has a groove, the position of which is adapted to the vertical rod 16. The inside of the groove has multiple locking teeth 17, which are adapted to locking blocks 18. The pull rope 20 can actively pull the locking block 18, causing the locking block 18 to engage with and secure the locking teeth 17.

[0025] The lower end of the handheld lever 1 is provided with a pull ring, which is fixedly connected to the pull rope 20. The pull ring and the handheld lever 1 are connected by a return spring. The return spring can keep the pull ring and the handheld lever 1 tightly connected.

[0026] When the fixed hook 7 cannot reach the desired attachment point, pull the lifting rod 2 upwards. The locking teeth 17 on the lifting rod 2 contact the locking block 18, causing the locking block 18 to rotate. Pushing the locking block 18 moves the lifting rod 2 upwards. After pushing the locking block 18, the locking block 18 resets, securing the locking teeth 17 and preventing the lifting rod 2 from falling back. When the lifting rod 2 needs to be reset, pull the pull ring. The pull ring, through the pull rope 20, drives the locking block 18 to rotate, removing the obstruction to the locking teeth 17 and resetting the lifting rod 2. When the fixed hook 7 engages the grounding wire, adjust the rotating ring to push the deflection ring 15 upwards, securing the grounding wire to the fixed hook 7. When the lifting rod 2 needs to be reset, the rope actively pulls the locking block 18, causing the locking block 18 to engage with the locking teeth 17.
