Efficient welding device

Abstract

The invention discloses a high-efficiency welding device, which includes an electric welding machine and a connecting piece. The connecting piece is composed of a vertical pole, a container fixed on the top of the vertical pole, and a shell sleeve arranged outside the top of the container. One cavity, the container on the right side of the first cavity is provided with a second cavity, the container above the left side of the first cavity is provided with a first sliding cavity, and the container below the second cavity is provided with The second sliding chamber, the first chamber is provided with a rotating shaft extending to the left and right sides, the extended section on the right side of the rotating shaft penetrates the inner wall of the container and penetrates into the second chamber and is connected in operation. There are retaining columns on the left and right sides of the rotating shaft, cables are wound around the rotating shaft between the retaining posts, a first wire is arranged inside the left side of the rotating shaft, and the left end of the cable is embedded in the rotating shaft and electrically connected to the first wire. A guide ring is provided around the outer circle of the left retaining column; the invention is simple in structure, easy to operate, can automatically rewind the cable, improves safety at the same time, and prevents accidental electric shock accidents.

Description

Technical field [0001] The invention relates to the technical field of welding, in particular to a high-efficiency welding device. Background technique [0002] At present, electric welding machines are more and more widely used. However, because the power supply line of electric welding machines is relatively short, it often affects the movement of electric welding machines during welding. In the current situation, similar phenomena generally use one or more connections. The board is lengthened and connected to achieve the purpose of plugging and powering the welding machine. However, after multiple wiring boards are connected, the power supply line has a certain length, which is very inconvenient when retracting, and the power supply line is randomly thrown on the ground during the power supply process, so the power supply line It is prone to various accidental damages, such as personnel stepping on, hard objects scratching, etc., resulting in damage to the outer insulation of ...

Problems solved by technology

[0002] At present, electric welding machines are more and more widely used. However, due to the relatively short power supply line of electric welding machines, it often affects the movement of electric welding machines during welding. In the past, when encountering similar phenomena, one or more wires are generally used. The board is lengthened and connected to achieve the purpose of plugging and powering the electric welding machine. However, after multiple terminal boards are connected, the power supply line has a certain length, which is extremely inconvenient when retracting, and the power supply line is thrown on the ground at will during the power supply process, so the power supply line It is easy to be damaged by various accidents, such as people stepping on it, scratching by hard objects, etc., which will cause damage to the outer insulation of the power supply line, resulting in a decrease in the life of the power supply line; Accidental touch may induce electric shock, and there is a great potential safety hazard
