Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, and more specifically, to a fixing device for insulators of a low-loss communication tower. Background Art

[0002] The fixing device for insulators of a communication tower is a device specifically designed to fix insulators on a communication tower. Its main purpose is to ensure the stable and safe installation of insulators on the communication tower, while reducing losses caused by improper installation or environmental factors. Insulators are indispensable components in power lines and communication lines, and their main function is to ensure electrical insulation between conductors and towers, as well as between conductors.

[0003] In actual applications, the existing fixing devices for insulators of communication towers often use fixing parts such as bolts for fixing at the joints, with a relatively complex structure and extremely troublesome installation and maintenance; and due to the multi-directional forces of the cable, such as wind force and cable tension, the force is unevenly distributed, which is prone to stress concentration. Over time, it will affect the service life of the joints and insulators, posing certain potential safety hazards. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for insulators of a low-loss communication tower to solve the problems of the complex structure and easy uneven force of the existing insulator fixing devices mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for insulators of a low-loss communication tower, which is used to connect a communication tower, an insulator, and a wire clamp, and a cable is connected to the wire clamp.

[0006] To solve the problems of the complex structure and easy uneven force of the existing insulator fixing devices, it at least includes a fixed installation box, which is fixedly connected to the communication tower, and a second slot is opened at the top of the fixed installation box;

[0007] A transfer installation box, which is arranged adjacent to one side of the fixed installation box, and a first slot is opened at the top of the transfer installation box;

[0008] An installation rod, which is arranged between the fixed installation box and the transfer installation box, and a plurality of insulators are installed on the installation rod. Ball heads are arranged at both ends of the installation rod, and one of the ball heads is detachably and rotatably connected to the second slot, and the other ball head is detachably and rotatably connected to the first slot;

[0009] And, another ball head rotatably connected to the first slot, which is fixedly connected to the wire clamp and is detachably connected to the first slot;

[0010] The ball heads inside the slots 1 and 2 are provided with limit assemblies, which are used to limit the ball heads from leaving the slots. By setting the connection between the insulator, the communication tower and the cable as a ball head and a slot structure, the ball head only needs to be inserted into the slot during installation, which is very convenient. The ball head can move freely left and right and up and down in the slot. The limit function of the limit assembly and the tension of the cable itself ensure that the ball head can only rotate in the slot, which can effectively solve the problem that the existing insulator fixing device is complex in structure and prone to uneven force.

[0011] As a further improvement of the technical solution, the limit assembly includes a limit box, the limit box is slidably sleeved on the wedge block, one end of the wedge block is set as a wedge-shaped structure, the other end of the wedge block is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the inner wall of the limit box, both sides of the wedge block are fixedly connected to the limit block 1, the inner walls on both sides of the limit box are fixedly connected to the limit block 2, and the limit block 2 is located on the side of the limit block 1 away from the spring. By setting the limit assembly, the ball head cannot leave the slot autonomously, and during installation, since the limit assembly exposed in the slot is a wedge-shaped structure, it is only necessary to insert the ball head into the slot to achieve installation. During disassembly, it is only necessary to use a tool to hold the limit assembly and then pull out the ball head.

[0012] As a further improvement of the technical solution, the first card slot is adapted to the size of two ball heads, and the second card slot is adapted to the size of one ball head. By setting the first card slot inside the transfer installation box to be able to accommodate two ball heads at the same time, it is convenient for both ends of the transfer to be engaged at the same time, which is beneficial to the transfer between the wire clamp and the insulator.

[0013] As a further improvement of the technical solution, a spherical structure is provided inside the first and second slots, and a gap is formed between the ball head and the first and second slots. The gap between the ball head and the slot is conducive to the free rotation of the ball head. By setting the interior of the slot as a spherical structure, the ball head can rotate freely in the slot, and at the same time, the insulator connection can cope with the uneven force caused by multiple forces such as wind force and tension.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. This low-loss communication tower insulator fixing device, by setting the connection between the insulator, the communication tower and the cable as a ball head and a slot structure, only needs to insert the ball head into the slot during installation, and the installation is very convenient; and the ball head can move freely left and right and up and down in the slot, coupled with the limiting effect of the limiting component and the tension of the cable itself, the ball head can only rotate in the slot, which can effectively solve the problem that the existing insulator fixing device is complex in structure and prone to uneven force.

[0016] 2. This low-loss communication tower insulator fixing device sets a limit assembly so that the ball head cannot leave the slot on its own. During installation, the limit assembly is exposed in the slot in a wedge-shaped structure, so installation can be achieved by simply inserting the ball head into the slot. During disassembly, it is only necessary to use a tool to hold the limit assembly and then pull out the ball head.

[0017] 3. This low-loss communication tower insulator fixing device, by setting a card slot inside a transfer installation box to accommodate two ball heads at the same time, facilitates the simultaneous engagement of the two ends of the transfer point, and is beneficial to the transfer between the wire clamp and the insulator; at the same time, the inside of the card slot is set to a spherical structure, which facilitates the free rotation of the ball head in the card slot.
