Technical Field
[0001] The utility model relates to the technical field of insulators, in particular to a conductor anti-detachment type insulator. Background Art
[0002] Currently, overhead installation is widely used in medium-voltage distribution networks, especially in mountainous areas. Conventional overhead line installation is fixed through post insulators or suspension insulators. It is easy to install and maintain, with low cost, but it is easily affected by weather and environment (such as strong winds, lightning strikes, dirt, ice and snow, etc.) and causes failures.
[0003] At present, column insulators usually use 4 to 6 square millimeter single-core aluminum wire to bind and fix the conductors. Operators may lack skills or be careless when binding, resulting in poor or non-standard binding effects. In addition, when the conductors are in operation, the binding wires will be exposed to the air for a long time, causing a certain amount of oxidation, which will affect the mechanical strength of the binding wires. In addition, under the action of force, the binding wires are very likely to loosen or break. Summary of the Invention
[0004] The purpose of the utility model is to provide a conductor anti-dropping insulator to solve the above-mentioned defects caused by the prior art.

The bottom end of the metal rod is connected to a U-shaped base. An adjustment mechanism is provided directly above the metal rod. The adjustment mechanism adjusts the angle of the metal rod according to the connection angle of the wire to prevent the wire from falling off due to excessive pulling force. A clamping mechanism is provided directly above the angle adjustment seat. The clamping mechanism clamps the wire and controls the clamping range according to the diameter of the wire, thereby improving the stability of clamping wires of different diameters.
[0006] Preferably, the adjustment mechanism includes an angle adjustment seat, a bolt seat, a fastener, a wire supporting rod and a fastening hole. The wire supporting rod is arranged directly above the angle adjustment seat, and the bolt seat is arranged directly below the angle adjustment seat. A fastener is connected to one side of the bolt seat. The angle adjustment seat is arranged directly above the metal rod, and fastening holes are distributed in a ring shape on the outer side of the wire supporting rod.
[0007] Preferably, the angle adjustment seat is connected to both sides of the metal rod through bolt seats symmetrically arranged at the bottom end.
[0008] Preferably, the clamping mechanism includes a wire supporting rod, a cover plate, a threaded rod, a nut, a contact groove and a clamp. A cover plate is arranged directly above the wire supporting rod, threaded rods are symmetrically arranged on both sides of the cover plate, nuts are connected to the outer side of the threaded rod, a contact groove is opened at the bottom end of the wire supporting rod, and clamps are symmetrically connected on both sides of the cover plate.
[0009] Preferably, the wire supporting rod is connected to the cover plate via threaded rods symmetrically arranged on both sides.
[0010] Preferably, the wire supporting rod contacts the top end of the metal rod through a contact groove provided at the bottom end.
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] 1. During the installation process, the angle of the wire support rod should be adjusted accordingly according to the installation position of the insulator, the environment in which the wires are deployed, and the installation angle of the wires in mountainous areas. The wire support rod and the clamp mechanism should be pulled to tilt them, thereby improving the stability of the parallel docking clamping between the wires and the clamps, and avoiding wear or oxidation of the metal surface of the wires due to excessive clamping force or twisting of the wires.
[0013] 2. During the installation process, clamp the metal wires exposed to the air, adjust the clamping distance between the wire support rod and the cover plate according to the diameter of the wire, and rotate and lock them with the nuts and threaded rods set on both sides.

The angle adjustment seat 4 is arranged directly above the metal rod 1, and the fastening holes 13 are distributed in a ring shape on the outer side of the wire supporting rod 9.
[0023] In this embodiment, the angle adjustment seat 4 is connected to both sides of the metal rod 1 through bolt seats 5 symmetrically arranged at the bottom end. The bottom end of the angle adjustment seat 4 is locked by the bolt seats 5, which facilitates quick disassembly and replacement of the angle adjustment seat 4.
[0024] In this embodiment, the clamping mechanism 8 includes a wire supporting rod 9, a cover plate 10, a threaded rod 11, a nut 12, a contact groove 14 and a clamp 15. The cover plate 10 is arranged directly above the wire supporting rod 9, and the threaded rods 11 are symmetrically arranged on both sides of the cover plate 10. The outer side of the threaded rod 11 is connected to the nut 12.

[0028] Step 1: The operator first positions the U-shaped base 3 provided at the bottom end of the metal rod 1 on the power tower or pole according to the installation requirements, locks the U-shaped base 3 with the expansion bolts, and then completes the locking of the bottom end of the metal rod 1. The bolt seat 5 provided at the bottom end of the angle adjustment seat 4 is connected to the two sides of the metal rod 1, and the bolt seat 5 and the two sides of the metal rod 1 are locked with the fasteners 6.
[0029] Step 2: The operator then pulls the wire supporting rod 9 according to the installation environment or the angle of the deployed wires, so that the wire supporting rod 9 rotates outside the angle adjustment seat 4, and then adjusts the angle of the wire supporting rod 9 to be parallel to the wires, inserts the bolt into the fastening hole 13 opened on the outside of the wire supporting rod 9, and locks the wire supporting rod 9 and the angle adjustment seat 4, so that the contact groove 14 opened at the bottom end of the angle adjustment seat 4 contacts the top end of the metal rod 1;
[0030] Step 3: The operator first places the wires on the surface of a group of clamps 15 set inside the wire supporting rod 9, and then clamps the other side of the wires with another group of clamps 15 set at the bottom end of the cover plate 10. At the same time, the threaded rods 11 set on both sides of the wire supporting rod 9 pass through the two sides of the cover plate 10, and are tightened with the outer side of the threaded rods 11 through the nuts 12.
