[0002] The torque locking connection device is a fixture that connects and fixes two or more sections of wires. The torque locking connection device has good conductivity and is generally made of highly conductive aluminum alloy high-pressure die-casting. The torque locking connection device is suitable for overhead power insulated conductor lines with a rated voltage of 10kV and below, and low-voltage lines in distribution and transformation stations. In order to prevent accidents caused by power supply, the device should be pre-installed in advance every 250m or so on 10kV overhead insulated conductor straight poles, T-type support poles and other poles in the early stage of line construction. It is used for electricity testing and grounding during maintenance work. The torque locking connection device is also suitable for the connection between the distribution network and the meter household branch line, the insulated copper and aluminum conductor main line and the meter household branch line. It is a non-bearing power connection hardware.

[0003] Most of the existing torque locking connection devices use screws to fix the cables. The screws squeeze the cables for too long, causing the cables to deform. In order to prevent the cables from sliding, threads are usually provided at the connection points to increase friction. The deformed cables will be embedded in the threads, which makes it more difficult to remove the cables when they are dismantled. Therefore, the present application proposes a torque locking connection device. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-2 As shown, the utility model proposes a torque locking connection device, including a main body 1:

[0025] Among them, a through hole 8 is opened at one end of the main body 1, and a thread is arranged in the through hole 8 for installing cables. A first screw 5 is fixedly installed on the main body 1, and one end of the first screw 5 passes through the top of the through hole 8, and is used to fix the cable in the through hole 8. An auxiliary mechanism for pushing the cable in the through hole 8 to move is arranged in the main body 1, which facilitates workers to take out the cables installed in the through hole 8 and improves work efficiency.

[0026] like Figure 2-3 As shown, the present embodiment also includes an auxiliary mechanism, which includes a push plate 6 slidably installed on one side of the main body 1, and is used to push the cable in the through hole 8 upward so that the cable and the through hole 8 are separated. A long rod 9 is fixedly installed at one end of the push plate 6, and a slide groove 11 is provided in the main body 1. The long rod 9 is located in the slide groove 11, and a guide cavity 23 is provided in the main body 1. One end of the guide cavity 23 is connected with the slide groove 11, and the other end of the guide cavity 23 is connected with the bottom of the through hole 8. A push block 12 is slidably installed in the guide cavity 23, and the bottom of the push block 12 is a section setting. When the push plate 6 is pushed, the push plate 6 drives one end of the long rod 9 to press against the section of the push block 12. As the long rod 9 continues to move, the push block 12 pushes the cable in the through hole 8 to move upward, so as to facilitate the extraction of the cable.

[0027] like Figure 2-4As shown, an extrusion plate 18 is slidably installed at one end of the slide 11, and a liquid storage bag 20 is fixedly installed on one side of the extrusion plate 18. Lubricant is arranged in the liquid storage bag 20, and a guide tube 17 is fixedly installed on the top of the liquid storage bag 20. A guide groove 19 is opened on the slide 11, and the guide groove 19 is connected with the through hole 8. The guide tube 17 is located in the guide groove 19. When the long rod 9 drives the extrusion plate 18 to move, the extrusion plate 18 squeezes the lubricant in the liquid storage bag 20 out of the guide tube 17 to lubricate the cable, making it easier to remove the cable.

[0028] like Figure 1-2 As shown, a mounting cavity 16 is opened in the main body 1, and mounting plates 13 are fixedly installed on both sides of the push block 12, and the mounting plates 13 are located in the mounting cavity 16. A guide column 15 is fixedly installed on one side of the mounting plate 13, and the guide column 15 is slidably connected to the mounting cavity 16. A first spring 14 is sleeved on the guide column 15, and the first spring 14 is fixedly connected to the mounting plate 13. When the long rod 9 cancels the squeezing of the push block 12, the first spring 14 rebounds, driving the push block 12 to reset, which is convenient for the subsequent installation of cables.

[0029] like Figure 2-4 As shown, a short rod 10 is fixedly installed on one side of the push plate 6, and the short rod 10 is slidably connected to the main body 1. A second spring 7 is sleeved on the short rod 10, and the second spring 7 is fixedly connected to the push plate 6. An elastic through hole 21 is opened on the main body 1, and an opening 2 is provided on one side of the elastic through hole 21. A threaded tube 3 is slidably installed in the elastic through hole 21, a second screw 4 is threadedly installed on one side of the main body 1, and stainless steel screws 22 are threadedly installed on both sides of the main body 1.

[0030] Working principle: when the cable needs to be pulled out, turn the first screw 5 to cancel the fixation of the cable and push the push plate 6. The push plate 6 drives one end of the long rod 9 to press against the cross-section of the push block 12. As the long rod 9 continues to move, the push block 12 pushes the cable in the through hole 8 to move upward, so that the cable is separated from the through hole 8. As the long rod 9 continues to move, when the long rod 9 drives the squeezing plate 18 to move, the squeezing plate 18 squeezes the lubricant in the liquid storage bag 20 from the guide tube 17 to lubricate the cable, thereby realizing the rapid removal of the cable, improving the removal efficiency, saving manpower, and being highly practical.

[0031] The above-mentioned specific embodiments are only several optional embodiments of the present invention.
