Description

Technical Field

[0001] This utility model relates to the field of wire clamps, specifically a wire clamp with an easy-to-tighten mechanism. Background Technology

[0002] In the power industry, an easy-tightening / loosening wire clamp is a tool used to fix and tighten conductors during the construction and maintenance of transmission lines. It mainly consists of a clamping body, a tightening / loosening mechanism, and connecting components. The clamping body employs a special structural design to firmly hold the conductor and prevent slippage. The tightening / loosening mechanism is the core innovation of this clamp. It typically uses a simple yet efficient mechanical transmission principle, such as a worm gear or lead screw and nut mechanism, allowing operators to easily tighten and loosen the clamp by rotating or pulling the operating components. This significantly reduces operational difficulty and labor intensity, improves construction and maintenance efficiency, and ensures the reliability and safety of conductor fixation during operation.

[0003] In the existing technology, in the maintenance of power equipment, the existing wire clamps have the problems of cumbersome fixing and loosening operations and low efficiency. When operating, maintenance personnel often need to spend a lot of time and energy to fix the wire clamp to position the conductor. After completing the maintenance task, it is difficult to quickly loosen and move it again. This inconvenience not only reduces work efficiency, but also increases the cost of manual operation and time. In order to solve this technical problem, this utility model proposes a wire clamp with an easy-to-tighten mechanism. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] Example 1: An easy-to-tighten wire clamp includes a wire clamping box 1. A rotating rod 3 is rotatably connected inside the wire clamping box 1. A cam 4 is fixedly connected to the bottom outer wall of the rotating rod 3. A sliding base 5 is slidably connected inside the wire clamping box 1, and the cam 4 corresponds to the sliding base 5. A pair of connecting rods 6 are fixedly connected to the top of both sides of the sliding base 5. A pressure block 7 is provided on both sides of the sliding base 5. Each pressure block 7 has an inclined groove 8 inside, and the connecting rod 6 passes through the pressure block 7 and is slidably connected in the inclined groove 8. A multi-tooth clamp 9 is fixedly connected to the outer wall of the pressure block 7. Wires 10 are provided on both sides of the wire clamping box 1. The wires 10 pass through the wire clamping box 1 and are slidably connected inside the wire clamping box 1. At the same time, the multi-tooth clamp 9 on both sides corresponds to the wires 10 on both sides. A handle 2 is fixedly connected to the top of the rotating rod 3. The cam 4 is rotatably connected inside the wire clamping box 1. At the same time, the sliding base 5 and the pressure block 7 are slidably connected inside the wire clamping box 1. A pair of springs 11 are fixedly connected to the other side of the sliding base 5, and the springs 11 are fixedly connected inside the wire clamping box 1.

[0025] When repairing electrical equipment, for ease of operation, the wire clamp 1 is used to flexibly fix and move the wire 10. The bolt 19 is unscrewed from the mounting hole 18, the wire 10 is placed in the wire hole between the two half-box wire clamps 1, and then fixed and limited with the bolt 19. The wire clamp 1 slides freely on the wire 10. One end of the handle 2 is fixed to the worker's belt. When repairing specific electrical equipment, the wire clamp 1 is fixed in the position of the corresponding wire 10. The handle 2 is pulled down by gravity, and the handle 2 will drive the cam 4 at the bottom of the rotating rod 3 to rotate. When the cam 4 rotates 90°, it will push the sliding base 5 upward. As the sliding base 5 moves upward, the pair of connecting rods 6 on both sides of the top will also move together. Since the connecting rods 6 move along the inclined groove 8, the connecting rods 6 will gradually push the pressure block 7 to move to both sides. When the pressure block 7 moves, it works in conjunction with the multi-tooth clamp 9 to move it to the outer surface of the conductor 10. Ultimately, the multi-tooth clamp 9 firmly presses the conductor 10, thus securing the wire clamp 1 securely to the conductor. When the maintenance work is completed, or when it is necessary to move the wire clamp 1 to another position, simply loosen the rope connected to the handle 2 on the belt, then lift the handle 2 to reset the cam 4. The spring 11 will then rebound, pushing the sliding base 5 back to its reset position. At the same time, the pressure block 7 will also reset, and the multi-tooth clamp 9 will detach from the conductor 10. The wire clamp 1 will then slide on the conductor 10. This method greatly facilitates workers to quickly maintain electrical equipment and effectively improves work efficiency.

[0026] Example 2: The difference between this example and Example 1 is that, in this example, a pair of limiting blocks 15 are fixedly connected to the bottom of the sliding base 5, a pair of inner grooves 16 are opened inside the wire clamping box 1, and the limiting blocks 15 are slidably connected inside the inner grooves 16. The inner grooves 16 effectively limit the movement direction of the sliding base 5. A pair of connecting plates 13 are fixedly connected inside the wire clamping box 1. The connecting plates 13 are located above the sliding base 5. At the same time, a sliding groove 14 is opened inside the connecting plates 13. A slider 12 is fixedly connected to the bottom of the pressure block 7. The slider 12 is slidably connected inside the sliding groove 14. The sliding groove 14 effectively limits the movement direction of the pressure block 7. A limiting ring 17 is fixedly connected to the top of each connecting rod 6. The wire clamping box 1 includes upper and lower halves of the box. At the same time, mounting holes 18 are opened at the four corners of the upper and lower halves of the box. The two halves of the box are connected by bolts 19 passing through the mounting holes 18.

[0027] Working principle: When workers inspect power transmission lines, this device is used for fixed support. First, the bolt 19 is unscrewed from the mounting hole 18. The wire 10 is placed in the through hole between the two half-boxes 1, and fixed with the bolt 19 to limit its movement, allowing the box 1 to slide freely on the wire 10. Then, one end of the handle 2 is fixed to the worker's belt. During maintenance, the box 1 needs to be firmly fixed to the position of the corresponding wire 10 of the power equipment being repaired. By pulling down the handle 2, the handle 2 drives the cam 4 at the bottom of the rotating rod 3 to rotate. When the cam 4 rotates 90°, it pushes the sliding base 5 upward. When the sliding base 5 moves, it is limited in the inner groove 16 by the limit block 15 to ensure consistent direction of movement. When the sliding base 5 moves upward, it drives the pair of connecting rods 6 on both sides of the top to move together. The connecting rod 6 moves along the inclined groove 8. Since the inclined groove 8 is inclined, the connecting rod 6 will gradually push the pressure block 7 to move to both sides when it moves. The limiting ring 17 can prevent the pressure block 7 from slipping off the connecting rod 6. When the pressure block 7 moves to both sides, it is limited by the slider 12 in the sliding groove 14 in the connecting plate 13 to ensure that the movement direction of the pressure block 7 is consistent. It also moves to the outer surface of the wire 10 with the help of the multi-tooth clamp 9. The multi-tooth clamp 9 firmly squeezes the wire 10 so that the wire clamp box 1 cannot move on the wire 10. When it needs to be loosened, the rope connected to the handle 2 on the belt is loosened and the handle 2 is lifted to reset the cam 4. At this time, the spring 11 will push the sliding base 5 back to reset it through the elasticity. The pressure block 7 resets and the multi-tooth clamp 9 is disengaged from the wire 10, so it can slide. This makes it convenient for the staff to quickly maintain the power equipment and improves the work efficiency.
