Description

Technical Field

[0001] This utility model belongs to the field of insulator technology, specifically a tension-type composite insulator. Background Technology

[0002] Tension-type composite insulators are insulating devices used in power engineering. Primarily made of composite materials, they are a special type of insulator capable of withstanding significant tensile forces while maintaining excellent insulation performance through specialized structural design and material selection. These insulators are commonly used on guy wires at power line terminals, corners, and broken poles to insulate the lower guy wire from the upper guy wire. Currently, the connection of tension-type composite insulators typically requires winding the guy wire multiple times or tightening screws with tools. Both of these connection methods are inconvenient and result in low connection efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a tension-type composite insulator, which solves the problem that existing tension-type composite insulators generally require winding the guy wire many times or using tools to tighten the screws for wiring. Both of these wiring methods are inconvenient to operate, resulting in low wiring efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tension-type composite insulator, comprising a tension-type composite insulator body, with connecting frames at both the top and bottom of the tension-type composite insulator body, a rotating rod rotatably connected to the connecting frame, a telescopic rod inside the connecting frame, a return spring sleeved on the telescopic rod, and two circular connecting plates fixedly connected to both ends of the telescopic rod, one of which is rotatably connected to the rotating rod, and the other is rotatably connected to the connecting frame, with a limit blocking block fixedly connected to the connecting frame.

[0005] As a further embodiment of this utility model: one end of the reset spring is fixedly connected to one of the circular connecting plates, and the other end of the reset spring is fixedly connected to another circular connecting plate.

[0006] As a further embodiment of this utility model: a roller is rotatably connected to the rotating rod, and limit sleeves are fixedly connected to both ends of the tensioned composite insulator body.

[0007] As a further embodiment of this utility model: the limiting connecting sleeve has two fastening screws threaded on it, and the limiting connecting sleeve has a connecting mounting post inside it.

[0008] As a further embodiment of this utility model: a connecting circular plate is fixedly connected to the top of the connecting mounting column, and the connecting circular plate is fixed to the connecting frame.

[0009] As a further embodiment of this utility model: the limiting block is located on one side of the roller, and two fastening screws are symmetrically arranged about the middle of the limiting connecting sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This tension-type composite insulator, by incorporating a rotating rod, a telescopic rod, a return spring, a limiting block, and a connecting frame, operates by pressing the annular structure at one end of the pull wire against the rotating rod, causing it to rotate. Simultaneously, the rotating rod compresses the telescopic rod and the return spring. After a period of time, the annular structure fits onto the connecting frame and no longer presses against the rotating rod. At this point, the return spring resets, pushing the rotating rod to rotate in the opposite direction. The annular structure is now inside the connecting frame, and the limiting block prevents the roller from rotating outwards, thus preventing the annular structure from detaching from the connecting frame. This completes the wiring of the tension-type composite insulator. Wiring is simple and quick, requiring only the annular structure at one end of the pull wire to press against the rotating rod, significantly improving wiring efficiency.

[0012] 2. This tension-type composite insulator, through the setting of a limiting connecting sleeve, fastening screws, and connecting mounting post, allows for easy disassembly of the connecting mounting post. When disassembly is required, the fastening screws are loosened to release the fixed state of the connecting mounting post, allowing it to be removed from the limiting connecting sleeve. When installation is required, the connecting mounting post is placed inside the limiting connecting sleeve, and the fastening screws are tightened to secure it, completing the installation. By disassembling and installing the connecting mounting post, the wiring assembly fixedly connected to it can also be disassembled and installed. The modular wiring assembly allows for easy disassembly and installation on a new tension-type composite insulator body after aging or damage, facilitating reuse and saving on operating costs.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a tension-type composite insulator, including a tension-type composite insulator body 1, with connecting frames 5 at both the top and bottom of the tension-type composite insulator body 1, a rotating rod 8 rotatably connected to the connecting frame 5, and a roller 9 rotatably connected to the rotating rod 8. Because of the roller 9, the sliding friction between the rotating rod 8 and the connecting frame 5 can be changed into rolling friction, thereby effectively reducing friction and improving the smoothness of the rotation of the rotating rod 8. This allows the ring structure at one end of the pull wire to easily push the rotating rod 8, thereby improving the ease of operation. Limiting connecting sleeves 2 are fixedly connected to both ends of the tension-type composite insulator body 1.

[0019] The connecting frame 5 is equipped with a telescopic rod 10. Because of the telescopic rod 10, when the return spring 12 is compressed, the telescopic rod 10 can restrict the return spring 12, preventing the return spring 12 from being deformed due to excessive bending caused by compression, thereby ensuring the normal operation of the return spring 12. The return spring 12 is sleeved on the telescopic rod 10. One end of the return spring 12 is fixedly connected to one of the circular connecting plates 11, and the other end of the return spring 12 is fixedly connected to another circular connecting plate 11. Both ends of the telescopic rod 10 are fixedly connected to the circular connecting plates 11. Because of the circular connecting plates 11, the circular connecting plates 11 provide connection points for the return spring 12. When the rotating rod 8 rotates, the return spring 12 can be squeezed through the circular connecting plates 11, thereby facilitating the normal operation of subsequent work.

[0020] There are two circular connecting plates 11. One circular connecting plate 11 is rotatably connected to the rotating rod 8, and the other circular connecting plate 11 is rotatably connected to the connecting frame 5. The limiting block 7 is located on one side of the roller 9, and two fastening screws 6 are symmetrically arranged about the middle of the limiting connecting sleeve 2.

[0021] A limiting block 7 is fixedly connected to the connecting frame 5. Because of the limiting block 7, when the annular structure at one end of the pull wire is inside the connecting frame 5, the limiting block 7 will block the roller 9, which can prevent the rotating rod 8 from rotating outward and causing the annular structure to detach from the connecting frame 5. This ensures that the annular structure is always inside the connecting frame 5, guaranteeing the normal connection between the annular structure and the connecting frame 5. Two fastening screws 6 are threadedly connected to the limiting connecting sleeve 2. Because of the fastening screws 6, tightening the fastening screws 6 can fix the connecting mounting post 3 and the wiring assembly, thereby greatly improving the stability of the connecting mounting post 3 and the wiring assembly. Loosening the fastening screws 6 can quickly disassemble the connecting mounting post 3 and the wiring assembly, allowing the wiring assembly to be installed on a new tension composite insulator body 1, facilitating the reuse of the wiring assembly and saving usage costs. The limiting connecting sleeve 2 is provided with a connecting mounting post 3, and a connecting round plate 4 is fixedly connected to the top of the connecting mounting post 3. The connecting round plate 4 is fixed to the connecting frame 5.

[0022] The working principle of this utility model is as follows:

[0023] In use, the ring structure at one end of the pull cable is pressed against the rotating rod 8, causing the rotating rod 8 to rotate. Simultaneously, the rotating rod 8 compresses the telescopic rod 10 and the return spring 12. After a period of time, the ring structure is fitted onto the connecting frame 5 and no longer presses against the rotating rod 8. At this point, the return spring 12 resets, pushing the rotating rod 8 to rotate in the opposite direction. The ring structure is now located inside the connecting frame 5, and the limiting block 7 blocks the roller 9, preventing the rotating rod 8 from rotating outwards and causing the ring structure to malfunction. The frame 5 is detached, thus completing the wiring work of the tensioned composite insulator body 1. When it is necessary to disassemble the connecting mounting post 3, loosen the fastening screw 6 to release the fixed state of the connecting mounting post 3. At this time, the connecting mounting post 3 can be taken out from the inside of the limiting connecting sleeve 2, thus completing the disassembly work of the connecting mounting post 3. When it is necessary to install the connecting mounting post 3, place the connecting mounting post 3 inside the limiting connecting sleeve 2 and tighten the fastening screw 6 to fix the connecting mounting post 3, thus completing the installation work of the connecting mounting post 3.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
