Description

Technical Field

[0001] The utility model relates to the technical field of ball head suspension rings, in particular to a ball head suspension ring convenient for disassembly and assembly. Background Technique

[0002] The ball head suspension ring is a connecting piece between the transmission line tower and the insulator. It is a connecting fitting composed of a spherical end and a ring end, and is an indispensable part of the transmission line. After retrieval, the patent with the Chinese patent authorization announcement number CN212935473U discloses a ball head suspension ring, which includes a ball head and a pin. An elastic device is arranged on one side of the pin, and the elastic device is arranged between the pin and the suspension ring or between the pin and the bottom of the ball head. After the pin is inserted into the ball head, under the elastic force of the elastic device, the pin is pushed up (or pressed down), so that the pin always fits against the bottom of the suspension ring, and at the same time, a pre-tightening force is provided, so that even after the pin is worn, the pin can still closely adhere to the bottom of the suspension ring. During installation, only the pin needs to be inserted into the ball head without using a hammer to knock, and the installation is convenient and fast. At the same time, because of its elastic device, the bottom of the suspension ring fits to eliminate the gap between the pin and the suspension ring. After long-term use, the pin will not loosen, and the service life of the ball head suspension ring is longer. However, when the ball head suspension ring is connected, the pin enters the inside of the ball head, presses and fits against the bottom of the suspension ring. At the same time, it is easy to cause the block to move downward due to the downward pressure of the suspension ring, resulting in the loosening of the position of the pin and the unstable position of the suspension ring after installation.

Detailed implementation mode

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the embodiment of the present utility model provides a ball head hanging ring that is convenient for disassembly and assembly, including a connecting seat 1 and a ball head 2. Inside the front side wall of the connecting seat 1, there are a spherical opening 15 and an opening 8. The opening 8 is arranged above the spherical opening 15. There is a round hole at the upper end opening of the connecting seat 1, and its diameter is smaller than the diameter of the ball head 2. The diameter of the ball head 2 is smaller than the diameter of the spherical opening 15. A moving cavity 6 is arranged inside the connecting seat 1. The moving cavity 6 is communicated with the spherical opening 15, and a limiting plate 5 is slidably connected inside the moving cavity 6. A tension spring 7 is fixedly installed between the bottom surface of the limiting plate 5 and the bottom surface inside the moving cavity 6. The ball head 2 is arranged inside the connecting seat 1. The upper end of the ball head 2 is fixedly connected with a connecting rod 3. The upper end of the connecting rod 3 is fixedly connected with a hanging ring 4. The diameter of the connecting rod 3 is smaller than the size of the opening 8. The distance between the bottom surface of the spherical opening 15 and the bottom surface inside the moving cavity 6 is equal to the thickness of the limiting plate 5. When installing the ball head 2, the ball head 2 enters the inside of the moving cavity 6 through the spherical opening 15 and is located above the limiting plate 5. Under the action of the tension spring 7, the position of the ball head 2 moved to the upper part can be conveniently reinforced.

[0019] In order to be able to conveniently move the limiting plate 5 up and down, fasten the position of the ball head 2 and facilitate its disassembly work. In this embodiment, as Figures 2-4 shown, a fixed tube 11 is fixedly installed inside the connecting seat 1. The limiting plate 5 is slidably sleeved on the tube wall of the fixed tube 11. When the limiting plate 5 moves inside the moving cavity 6, it will move up and down on the fixed tube 11, which can strengthen the stability of the position of the limiting plate 5. A knob 9 is rotatably connected inside the top surface of the connecting seat 1. A screw rod 14 is rotatably connected inside the fixed tube 11. And a moving groove 13 is arranged inside the left side wall of the fixed tube 11. A moving block 12 is slidably connected inside the moving groove 13 and is threadedly sleeved on the rod wall of the screw rod 14. The moving block 12 is fixedly connected to the part where the limiting plate 5 is slidably connected to the fixed tube 11. The upper end of the screw rod 14 penetrates through the top surface inside the connecting seat 1 and is fixedly connected to the bottom of the knob 9. When moving the limiting plate 5 up and down, rotate the knob 9 to make the screw rod 14 rotate, so that the moving block 12 can conveniently drive the limiting plate 5 to move up and down, and use the limiting plate 5 to press against the placed ball head 2.

[0020] It should be noted that in this embodiment, when using the ball head hanging ring that is convenient to disassemble and assemble, as Figures 1-4 shown, when installing the ball head 2, rotate the knob 9 to rotate the screw rod 14, so that the moving block 12 can conveniently drive the limiting plate 5 to move downward, so that the ball head 2 enters the inside of the moving cavity 6 through the spherical opening 15 and is located above the limiting plate 5. Then rotate the knob 9 to move the limiting plate 5 upward. The tension spring 7 can strengthen the stability of the position of the limiting plate 5. After the limiting plate 5 moves upward, it presses against the placed ball head 2 to strengthen the stability of its position. The connecting rod 3 can move above the connecting seat 1 through the opening 8 by the rotation of the ball head 2, making the installation and disassembly of the ball head hanging ring more convenient.
