Welding device

Abstract

The invention discloses a welding device which comprises an electric welding machine and a connector, wherein the connector is formed by combining an upright rod, an accommodating tank fixed at the top of the upright rod and a shell sleeve arranged at the outer side of the top of the accommodating tank; a first accommodating cavity is arranged in the accommodating tank; a second accommodating cavity is arranged in the accommodating tank at the right side of the first accommodating cavity; a first slide cavity is arranged in the accommodating tank at the upper part of the left side of the first accommodating cavity; a second slide cavity is arranged in the accommodating tank at the lower part of the second accommodating cavity; a rotating shaft which extends towards the left and right sides is arranged in the first accommodating cavity; an extension segment at the right side of the rotating shaft runs through the inner wall of the accommodating tank, penetrates into the second accommodating cavity and is in running fit connection; bumping posts are equally arranged on the left and right of the rotating shaft in the first accommodating cavity; a cable is wound on an upper coil of the rotating shaft between the bumping posts; a first wire is arranged in the left side of the rotating shaft; the end of the left side of the cable is embedded into the rotating shaft and is electrically connected with the first wire; and a guide ring is wound on an external circle of the bumping post at the left side. The welding device is simple in structure and convenient to operate, the cable can be automatically wound, meanwhile, the security is improved, and an electric shock accident is avoided.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding device. Background technique [0002] At present, electric welding machines are used more and more widely. 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, one or more wires are usually used to encounter similar phenomena. 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 that the power supply line It is easy to be damaged by various accidents, such as trampling by people, scratching by hard objects, etc., which will cause damage to the outer ins...

[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
