Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission line technology, and in particular to a ball head hanger for power transmission lines. Background Technology
[0002] According to different installation methods, electrical fittings are divided into two main categories: special-purpose connecting fittings and general-purpose connecting fittings. Special-purpose connecting fittings refer to ball-head hangers and cup-head hangers for connecting insulators. Among them, the ball-head hanger is a round iron device used to connect insulating suspension plates.
[0003] A search revealed a ball-head hanger for power transmission lines, with publication number CN213425741U, relating to the field of power fittings technology. It includes a cylindrical rod with external threads on its outer wall. A collar is fitted onto the cylindrical rod, and an annular groove is formed on the inner wall of the collar. Internal threads one and two are respectively located on the upper and lower sides of the annular groove on the inner wall of the collar. A fixing ring is fixedly connected to the top of the cylindrical rod. This ball-head hanger for power transmission lines, through the external threads on the cylindrical rod and the internal threads one and two on the collar, allows the collar to descend outside the cylindrical rod when rotated. Simultaneously, through the annular groove and the sliding connection with two sliders, a lifting rod can be driven to slide downwards within a receiving groove, thereby adjusting the height of the ball-head hanger. This allows for adjustment of its length product to accommodate different structural gaps, improving its applicability and making it more convenient to use.
[0004] The above-mentioned limitations in the device's length adjustment range and the single hanging ring will reduce its applicability. Furthermore, when the device is not in use, it is inconvenient to protect its surface, thus reducing its lifespan. Utility Model Content
[0005] The purpose of this utility model is to provide a ball head hanger for power transmission lines to solve the problems mentioned in the background art.
[0006] The technical solution of this utility model is a ball-head hanging ring for power transmission lines, including a cylinder. The inner cavity of the cylinder is provided with a vertical rod. A blind hole is opened at the top of the vertical rod. A spring is fixedly connected in the blind hole. The top of the spring is fixedly connected to the top of the inner cavity of the cylinder. A first circular frame is fixedly connected to the bottom of the vertical rod. A second circular frame is fixedly connected to the bottom of the first circular frame. A U-shaped block is fixedly connected to the top of the cylinder. A T-shaped rod is hinged to the inner cavity of the U-shaped block. A fixing ring is fixedly connected to the end of the T-shaped rod away from the U-shaped block.
[0007] In one embodiment, vertical grooves are provided on both the left and right sides of the cylinder, and horizontal bars are fixedly connected to both sides of the vertical bar near the top. The ends of the horizontal bars away from the vertical bars pass through the adjacent vertical grooves.
[0008] In one embodiment, a disc is fixedly connected to the end of the crossbar away from the vertical bar, and a connecting column is fixedly connected to the side of the disc away from the cylinder. An elastic rod is fixedly connected to the top of the connecting column, and the top of the elastic rod is fixedly connected to the outer edge of the T-shaped bar.
[0009] In one embodiment, a telescopic tube is fixedly connected to the top of the first circular frame, and a connecting ring is fixedly connected to the top of the telescopic tube.
[0010] In one embodiment, the outer edge of the connecting ring is provided with four first threaded holes, and the outer edge of the cylinder is provided with four second threaded holes near the bottom. Each of the first threaded holes is threaded with a threaded rod, and one end of the threaded rod is threaded into an adjacent second threaded hole.
[0011] In one embodiment, a flange is fixedly connected to the outer edge of the second circular frame near the bottom, and the flange has a plurality of third threaded holes in its inner cavity, each of which is threaded with a bolt.
[0012] In one embodiment, a plurality of the bolts are arranged in a circular array with the center of the flange as the center.
[0013] The beneficial effects provided by this utility model are:
[0014] Through the cooperation of structures such as the cylinder, vertical rod, spring, and fixing ring, the bolt can be rotated to the flange to fix the device in place. When the length of the device needs to be adjusted, the cylinder is pulled, which moves the T-shaped rod and the fixing ring. The cylinder also stretches the spring, allowing the cylinder to move on the surface of the horizontal rod. The horizontal rod limits the maximum range of movement of the cylinder. During the movement of the cylinder, the T-shaped rod stretches the elastic rod, and the angle of the fixing ring can be adjusted. The fixing ring causes the T-shaped rod to swing, and the T-shaped rod swings inside the U-shaped block. When the device is not in use, the threaded rod is rotated to remove it from the cylinder and connecting ring. Moving the connecting ring causes the telescopic tube to stretch upward. The telescopic tube and the connecting ring protect the surface of the cylinder, thereby extending the service life of the device. Attached Figure Description

[0023] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a ball-head hanging ring for power transmission lines includes a cylinder 1. The inner cavity of the cylinder 1 is provided with a vertical rod 12. A blind hole is opened at the top of the vertical rod 12. A spring 16 is fixedly connected in the blind hole. The top of the spring 16 is fixedly connected to the top of the inner cavity of the cylinder 1. A first circular frame 8 is fixedly connected to the bottom of the vertical rod 12. A second circular frame 9 is fixedly connected to the bottom of the first circular frame 8. A U-shaped block 2 is fixedly connected to the top of the cylinder 1. A T-shaped rod 3 is hinged in the inner cavity of the U-shaped block 2. A fixing ring 4 is fixedly connected to the end of the T-shaped rod 3 away from the U-shaped block 2. Vertical grooves are opened on both the left and right sides of the cylinder 1. A horizontal rod 17 is fixedly connected to the left and right sides of the vertical rod 12 near the top. The end of the horizontal rod 17 away from the vertical rod 12 passes through the adjacent vertical groove. A disc 7 is fixedly connected to the end of the horizontal rod 17 away from the vertical rod 12. A connecting post 5 is fixedly connected to the side of the disc 7 away from the cylinder 1. An elastic rod 6 is fixedly connected to the top of the connecting post 5. The top of the elastic rod 6 is fixedly connected to the outer edge of the T-shaped rod 3.
[0024] The top of the first circular frame 8 is fixedly connected to a telescopic tube 15, and the top of the telescopic tube 15 is fixedly connected to a connecting ring 13. The outer edge of the connecting ring 13 has four first threaded holes, and the outer edge of the cylinder 1 near the bottom has four second threaded holes. Each of the first threaded holes is threaded with a threaded rod 14, and one end of the threaded rod 14 is threaded into an adjacent second threaded hole.

[0025] Working principle: Rotate bolt 11 to flange 10 to fix the device in place. When the length of the device needs to be adjusted, pull cylinder 1. Cylinder 1 moves T-shaped rod 3 and fixing ring 4, which in turn stretches spring 16. Cylinder 1 moves on the surface of crossbar 17, which limits the maximum range of movement of cylinder 1. When cylinder 1 moves, T-shaped rod 3 stretches elastic rod 6. The angle of fixing ring 4 can be adjusted, and fixing ring 4 swings T-shaped rod 3 within U-shaped block 2. When the device is not in use, rotate threaded rod 14 to remove it from cylinder 1 and connecting ring 13. Move connecting ring 13, which stretches telescopic tube 15 upward. Telescopic tube 15 and connecting ring 13 protect the surface of cylinder 1, thereby extending the service life of the device.
