Stable welding device

Abstract

The invention discloses a stable welding device which comprises a distribution seat and a tight insertion part. The distribution seat is fixed to the wall through a bolt. A voltage converter is arranged on the part, above the distribution seat, of the front end face of the wall. The voltage converter is electrically connected with the distribution seat through a line. An external threaded part is arranged on the front end face of the distribution seat. A through groove is formed in the external threaded part, and a tight insertion hole is formed in the position, on the rear side of the through hole, in the distribution seat. A second insertion piece is arranged on the inner wall of the rear side of the tight insertion hole. A first containing cavity is formed in the position, behind the tight insertion hole, in the distribution seat. A containing groove is formed in the inner wall of the rear side of the first containing cavity. A push block is arranged at the position, on the front side of the containing groove, in the first containing cavity. A compression spring is arranged between the end face of the rear side of the push block and the containing groove, sliding rods are symmetrically arranged at the positions, on the two sides of the compression spring, in the first containing cavity, and the sliding rods are matched and connected with the push block in a sliding manner. The stable welding device is simple in structure, convenient to operate, stable in power supply connection and capable of preventing the phenomenon that electric arcs are generated during inserting and pulling, and consequently electric shock accidents happen, and power supply safety and stability are improved.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a stable welding device. Background technique [0002] At present, welding machines are used more and more widely, and they rely on the power supply connection to work normally. Therefore, whether the power supply connection of the welding machine is stable and the safety of the power supply connection is the basis for determining whether the welding machine can work normally. The voltage required by the machine is relatively high, and it is easily affected by the voltage when plugging and unplugging, and it is easy to generate an arc. The generation of the arc is likely to cause an electric shock to the user. The power supply mode of the electric welding machine is plug-in, which is easy to be affected by external factors such as dragging and pulling, which will make the plug-in loose, cause poor contact, and bring inconvenience to the welding work.
