Description

Electric wire fixing device
Technical Field
The invention relates to the technical field of wire installation, in particular to a wire fixing device.
Background
The electric wire is a conducting wire for transmitting electric energy, and consists of one or more flexible conducting wires, and a light and soft protective layer is wrapped outside the conducting wire. The outer wall of the electric wire is clamped by an electric wire clamp in the installation and use processes of the electric wire so as to fix the position of the electric wire. The existing electric wire fixing device can only be used for clamping a single electric wire, and if the number of the electric wires required to be installed and fixed in a certain area is large, the electric wire fixing tool is consumed too much, waste is caused, and the cost is increased; and the excessive use of the wire fixing device may cause serious damage to the installed area, such as the wall surface, the ground surface, etc. However, when one electric wire fixing device is used for clamping a plurality of electric wires, the outer walls of the electric wires are extruded together, so that the single electric wire is inconvenient to maintain independently, and the electric wire becomes thick or thin due to the expansion caused by heat and the contraction caused by cold in hot weather, so that the outer wall of the electric wire is cut by the electric wire fixing device to cause electric leakage, or the electric wire cannot be clamped, and the potential safety hazard of the electric wire in the using process is brought.
Disclosure of Invention
The invention aims to provide an electric wire fixing device to solve the problems that the electric wire fixing device cuts the outer wall of an electric wire and cannot clamp the electric wire due to the action of expansion caused by heat and contraction caused by cold.
The basic scheme provided by the invention is as follows: the electric wire fixing device comprises a fixing sleeve and a spiral steel bar, wherein the fixing sleeve is arranged on an electric wire laying surface, the spiral steel bar penetrates through a power supply line, a clamping device and a tension sensor are arranged on the fixing sleeve, and the tension sensor is connected with a display through a controller; the fixed cover inner wall is equipped with the spiral guide way that supplies spiral billet screw in, is equipped with the joint spare of fixed spiral billet one end in the spiral guide way, but the joint spare manual control or automatic control, the spiral billet other end passes clamping device and stretches out outside fixed cover.
The electric wire laying surface refers to a place where electric wires need to be fixedly installed.
The working principle of the basic scheme is as follows: this scheme can be with this electric wire fixing device ann at the electric wire face of laying, the spiral billet is in advance in the fixed cover through the spiral guide way precession, the one end that the spiral billet got into fixed cover is fixed by the union piece, the other end of spiral billet passes clamping device and stretches out outside fixed cover, then pass the spiral billet with many electric wires, loosen clamping device, the one end that pulling spiral billet stretches out fixed cover, exert pressure to many electric wires, the display receives tensile size of demonstration under the pulling force of spiral billet through force transducer this moment, wherein, detect out the taut required suitable pulling force with many electric wires according to the electric wire radical in advance, then according to demonstration value adjustment pulling force size, thereby press from both sides tight many electric wires, it has avoided damaging the electric wire outer wall because of the pulling force is too big, then tightly close clamping device fixed spiral. This scheme still can be earlier with fixed cover ann at the electric wire face of laying, and many electric wires pass fixed cover, then pass through the fixed cover of spiral guide way screw in with the spiral billet, and the one end that the spiral billet got into fixed cover is fixed by the card union piece, then the pulling spiral billet stretches out the outer one end of fixed cover, presss from both sides tight many electric wires, and rethread clamping device has fixed the spiral billet.
The basic scheme has the beneficial effects that: 1. according to the invention, the steel bars are used for clamping a plurality of electric wires, and the steel bars have good thermal expansion and cold contraction performance, so that the steel bars can deform along with the electric wires when the electric wires become thick or thin due to thermal expansion and cold contraction, thereby clamping the plurality of electric wires all the time, and avoiding the problems of electric leakage caused by the cutting of the outer walls of the electric wires or incapability of clamping the electric wires. Compared with the existing electric wire fixing device, the electric wire fixing device greatly protects the electric wire and reduces excessive consumption of the electric wire fixing device.
