[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment of a high-voltage power fitting for power lines, comprising two adjusting sleeves 1, which are the external structure of the entire device and can withstand the working environment of high-voltage power lines. The internal threads of the two adjusting sleeves 1 are connected with adjusting columns 2, and the distance between the two adjusting sleeves 1 can be changed by rotation. The left and right sides of the adjusting column 2 are fixedly connected with a tension rope 3 to adjust the tension of the tension rope 3. When the adjusting column 2 rotates, the two adjusting sleeves 1 can move synchronously. An external side of the adjusting sleeve 1 is fixedly connected with an adjusting seat 7, which is an external structure of the device and is used to install and fix cables.

[0032] The tension rope 3 is a high-strength rope used to transmit the rotational torque of the adjustment column 2 to the adjustment seat 7, thereby changing the distance between the two adjustment seats 7. The other side of the tension rope 3 is fixedly connected to the limit plate 1, which is used to limit the sliding range of the tension rope 3. The adjustment sleeve 1 is equipped with an adjustment component inside to assist in the adjustment of the tension rope 3.

[0033] The adjustment component includes a connecting chamber 4, the outside of which is fixedly connected to the inside of the adjusting sleeve 1. It is a cavity inside the adjusting sleeve 1 for accommodating a spring 5 and a limit plate 6. The outside of the connecting chamber 4 is fixedly connected to the inside of the adjusting sleeve 1, so that the entire adjustment component can be stably installed in the adjusting sleeve 1. The outside of the tension rope 3 is slidably connected to the internal through hole of the connecting chamber 4. It is a compression spring located inside the connecting chamber 4. The inside of the connecting chamber 4 is fixedly connected to a spring 5, and the other end of the spring 5 is fixedly connected to the side of the limit plate 6 away from the tension rope 3.

[0034] Limiting plate 1 (6) is a metal plate located inside the connecting chamber 4, with its exterior slidingly connected to the inner wall. Its primary function is to limit the sliding range of the tension cord 3, preventing it from slipping out of the connecting chamber 4. One end of the limiting plate is fixedly connected to the bottom of the connecting chamber 4, and the other end is fixedly connected to the side of the limiting plate 1 (6) facing away from the tension cord 3. When the adjusting column 2 rotates, the spring 1 (5) is compressed, generating a reaction force on the limiting plate 1 (6), thereby providing a buffering and anti-slip effect.

[0035] Reference Figure 4 The adjustment seat 7 has a limit slot 8 defined within it. Two sliders 9 are slidably connected to the inner wall of the limit slot 8. These sliders 9 are a structure within the adjustment seat 7 that guides the sliding direction of the sliders 9. A clamping plate 10 is fixedly attached to the outside of the sliders 9, located within the limit slot 8. The main function of the sliders 9 is to drive the clamping plates 10 to slide along the limit slot 8, thereby securing the cable.

[0036] A limit assembly is provided on the outside of the adjustment seat 7, and the limit assembly can fix the cable. The limit assembly includes a connecting post 11, the outside of which is slidably connected to the inside of the two clamping plates 10. The front and rear sides of the connecting post 11 are fixedly connected to a second limit plate 12, which is located inside the two clamping plates 10 and the outside is slidably connected to the inside of the clamping plates 10. The front and rear sides of the connecting post 11 are fixedly connected to the second limit plate 12, which is used to limit the sliding range of the clamping plates 10. The second limit plate 12 is located on the front and rear sides of the connecting post 11 and is used to limit the sliding range of the clamping plates 10. The second limit plate 12 is fixedly connected to the connecting post 11, so that when the clamping plates 10 slide, the second limit plate 12 can move accordingly, thereby maintaining the limiting effect on the clamping plates 10.

[0037] The outer sleeve of the connecting column 11 is provided with a second spring 13, one end of which is fixedly connected to the outer side of one of the clamping plates 10, and the other end of which is fixedly connected to the outer side of one of the limiting plates 12. The second spring 13 is located on the outer side of the connecting column 11, with one end fixedly connected to the outer side of one of the clamping plates 10, and the other end fixedly connected to the outer side of one of the limiting plates 12. When the clamping plates 10 are forced to slide outward, the second spring 13 will be compressed and generate a reaction force on the clamping plates 10, thereby playing a role in buffering and preventing slipping. The internal threads of the two clamping plates 10 are connected to a fixing bolt 14, and the external threads of the fixing bolt 14 are connected to two nuts. The fixing bolt 14 is located inside the two clamping plates 10 and is used to connect and fix the two clamping plates 10.

[0038] By rotating the fixing bolt 14, the two clamping plates 10 can be moved closer or further away from each other, thereby adjusting the clamping force on the cable. The outer surface of the adjustment column 2 is fixedly connected to the anti-slip sleeve 15. This is a rubber product that is installed on the outer surface of the adjustment column 2 to increase friction when holding. The outer surface of the anti-slip sleeve 15 is fixedly connected to the outer surface of the adjustment column 2 to prevent slipping during use. The outer surface of the anti-slip sleeve 15 is fixedly connected to multiple anti-slip bumps to further improve the anti-slip effect.

[0039] Working principle: First, place the cable in the middle of the splint 10. At this time, the slider 9 slides on the inner wall of the limit groove 8. At the same time, the splint 10 is forced to slide outward on the outside of the connecting column 11. The spring 2 13 is compressed and generates a reaction force on the splint 10. Then, the splint 10 is fixed with the fixing bolt 14 according to the thickness of the cable.

[0040] Then hold the anti-slip sleeve 15 and rotate the adjusting column 2 as needed, so that the adjusting column 2 rotates inside the adjusting sleeve 1. When the adjusting column 2 rotates counterclockwise, the external adjusting sleeve 1 moves to both sides. At this time, the tension rope 3 is stretched and the distance between the two adjustment seats 7 becomes larger. When the adjusting column 2 rotates clockwise, the distance between the two adjustment sleeves 1 decreases. At the same time, the tension rope 3 will push the limit plate 6 to slide inside the connecting compartment 4, so that the spring 5 is compressed and generates a reaction force on the limit plate 6, which can play a buffering and anti-slip role for the tension rope 3. At this time, the distance between the two adjustment seats 7 is reduced.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
