[0002] With the development of the electric power industry, the erection and maintenance of transmission lines have become increasingly important. As an important component in the transmission line, the design of the hanging ring directly affects the stability and safety of the line. Traditional hanging ring designs often have problems such as complex structure, inconvenient installation, and easy wear. Regarding the ball head hanging ring for transmission lines, the Chinese patent with publication number: CN218733101U discloses a ball head hanging ring for transmission lines, including: the hanging ring is provided with a connecting rod, and the connection is provided with a connecting hole; the ball head is provided with a sliding rod, and the sliding rod is provided in the connecting hole; the adjustment structure includes: a pin hole provided on the side wall of the connecting rod, and a positioning pin is slidingly provided in the pin hole; the pin hole is provided with a push spring, and the side wall of the sliding rod is provided with a circular groove, and the push spring pushes the positioning pin to move toward the circular groove; the end of the pin hole away from the connecting hole is provided with a limit hole perpendicular to the pin hole, and a limit rod is provided in the limit hole; wherein, the limit rod is inserted into the limit hole, and the two ends of the positioning pin are respectively in contact with the limit rod and the circular groove. Through the cooperation between the sliding rod and the connecting hole, the sliding rod can slide in the connecting hole, so that the length of the ball head hanging ring for the transmission line can be adjusted very conveniently.

[0032] In this embodiment, the ball head fixing mechanism 5 includes a rotating sleeve 51, a threaded guide column 52 and a fixing clamp 53. The rotating sleeve 51 is rotatably connected to the connecting rod 2. The surface of the connecting rod 2 is provided with a limit groove 24 for the rotating sleeve 51 to rotate. The lower end of the rotating sleeve 51 is provided with an internal thread engaged with the threaded guide column 52. The inner side of the threaded guide column 52 is provided with an inclined surface. The outer side of the fixing clamp 53 is provided with an inclined surface that fits the inner side of the threaded guide column 52. The fixing clamp 53 is stacked and arranged on both sides of the connecting rod 2.

The lower surface of the connecting rod 2 is provided with a translation groove 26 for the translation guide rod 54 to translate.

[0033] In this embodiment, the rotating sleeve 51 rotates, and due to the interaction between the internal and external threads, the threaded guide pin 52 moves along the axial direction of the connecting rod 2 based on the guiding action of the translation guide rod 54. The guide rod 55 effectively ensures that the threaded guide pin 52 remains stable when moving up and down. When the threaded guide pin 52 moves upward, the inclined surface on its inner side pushes the fixing clamp 53 closer to the ball head 3. The cooperation between the translation guide rod 54 and the translation groove 26 enables the fixing clamp 53 to remain stable during the translation process, ensuring the accuracy of the fixing effect. The ball head 3 is fixed by the fixing clamp 53, and the friction with the surface of the ball head 3 is increased based on the anti-slip groove, effectively preventing the ball head 3 from sliding or falling off during the fixing process.

[0034] When the screw thread guide post 52 moves upward, the inclined surface on the inner side pushes the fixing clamp 53 toward the ball head 3, thereby fixing the ball head 3.

[0035] In order to better demonstrate the installation and use of the transmission line ball head hanging ring, the present invention provides a method for using the transmission line ball head hanging ring, comprising the following steps:

[0036] Step 1: Install the ball head 3 at the lower end of the connecting rod 2, ensuring that the ball head 3 can slide freely under the guidance of the connecting rod 2. According to the actual installation needs, rotate the fixing screw 11 to stably fix the hanging ring body 1 on the installation clamp to prevent the hanging ring body 1 from accidentally loosening and causing wear on the inner side of the hanging ring body 1, thereby extending the service life of the transmission line ball head hanging ring;

[0037] Step 2: Pull the adjustment ring 42 to connect the movable groove 21 to the external environment, adjust the length of the ball head 3 to suit the actual installation requirements, and after adjusting the ball head 3 to the appropriate length, loosen the adjustment ring 42 to ensure the vacuum inside the movable groove 21, further improving the stability of the connection between the ball head 3 and the connecting rod 2;

[0038] Step 3: Rotate the rotating sleeve 51, and the threaded guide column 52 moves upward, thereby pushing the fixing clamp 53 to move toward the ball head 3 to fix the ball head 3. It can adapt to ball heads 3 of different sizes. Embed the ball head 3 on one side of the insulating suspension piece to complete the installation, ensuring that the ball head 3 is firmly fixed to prevent loosening or falling off during power transmission.
