Problems solved by technology

There are the following disadvantages in the existing line porcelain bottle binding: 1. The structure design is complicated, the installation is not convenient, and it is not conducive to high-altitude operations; 2. The binding process is not uniform, and the manual binding is loose or tight. The porcelain bottle falls off, and the wire falls on the support (crossarm), causing grounding, causing a trip, causing a power outage on the entire line or blowing the wire, which increases the maintenance workload and brings danger and loss to people's lives and property

Embodiment 1

[0020] The binding-free lock structure used in this embodiment is as follows: Figure 1~4 As shown, it includes an insulator 10, two clamping blocks 20 symmetrically arranged on both sides of the insulator 10, and a pressing block 21. One end of the two clamping blocks 20 is respectively provided with a clamping clamp on both sides of the insulator 10. Sheet 201, screw rods 202 are respectively provided on the two clamping blocks 20, and the screw rods 202 of the two clamping blocks 20 respectively pass through the through holes 212 on the pressing block 21 and are screwed with nuts 23, and the pressing block 21 is provided with The insulating slug 22, the insulating slug 22 is provided with an arc-shaped pressure groove 221, and the insulator 10 is provided with an arc-shaped accommodation groove 101 matching the arc-shaped pressure groove 221, and the insulating slug 22 and the insulator 10 A clamping cavity 100 for clamping the wire is formed therebetween. A cotter pin 24 ...

Embodiment 2

[0024] The wire fixing and binding-free locking structure adopted in this embodiment is as follows: Figure 5 and 6 As shown, the difference between the second embodiment and the first embodiment is that: two clamping blocks 20 are respectively provided with threaded holes 203, two through holes 212 of the pressure block 21 are respectively provided with a bolt 25, two The bolts 25 respectively pass through the two through holes 212 of the pressing block 21 and are respectively connected in the threaded holes 203 of the two clamping blocks 20 . The two clamping blocks 20 and the pressing block 21 are connected by bolts 25, so as to facilitate the assembly of the two clamping blocks 20 and the pressing block 21, and the assembly is more convenient. A bolt 25 is respectively arranged in the two through holes 212 of the pressure block 21, and the two bolts 25 are respectively connected in the threaded holes 203 of the two clamping blocks 20, and the bolts 25 are tightened, and t...

Abstract

The invention relates to a binding-free lock-type wire fixing method. The fixing components used include an insulator, a pressing block and two arc-shaped clamping blocks. groove, the lower surface of the pressing block is installed with an insulating insert, and the insulating insert is snapped into the pressing block in advance. On the wire, clamp and position it on the wire through the limit blocks on both sides of the insulating insert, place two arc-shaped clamping blocks symmetrically on both sides of the trumpet-shaped neck at the upper end of the insulator, and place the two clamping blocks It is connected with the pressing block through a screw or a bolt, and the clamping block and the pressing block are locked to lock the wire. The invention has the advantages of simple structure, stable and reliable performance, low cost and convenient installation.

Description

technical field [0001] The invention relates to the technical field of wire and cable installation and fixation, in particular to a binding-free lock-type wire fixing method. Background technique [0002] At present, in the power system of our country, the porcelain vases (insulators) on the straight rods in the distribution lines are all bound with aluminum wires to fix the wires, that is, the porcelain vases are manually bound to fix them. There are the following disadvantages in the existing line porcelain bottle binding: 1. The structure design is complicated, the installation is not convenient, and it is not conducive to high-altitude operations; 2. The binding process is not uniform, and the manual binding is loose or tight. Porcelain bottle comes off, and lead falls on the support (crossarm), causes grounding, causes tripping, and makes the whole line blackout or lead blown, and this makes maintenance work load increase, brings the danger and loss on people's life and...
