Welding device

Abstract

The invention provides a welding device comprising a power distribution seat and a plug arranged in the top of a power distribution box, wherein an insertion rod is fixedly arranged on a lower end of the plug, a conical part and a pointed needle part located on the lower end of the conical part are arranged on the lower end of the insertion rod, a lock hole extending left and right is formed in the middle of the pointed needle part, a sliding cavity is arranged in the power distribution seat, upper chutes are formed in a top wall of the sliding cavity in a left and right corresponding manner, slots connecting with the outer side are formed in the top walls of the upper chutes, a slide block is installed in the sliding cavity in an up and down sliding manner, sliding arms are arranged on the upper end of the slide block in the left and right corresponding manner, conical grooves are formed in the sliding arms, connection grooves for connecting the conical grooves are formed in the slide block in the left and right corresponding manner, an electric contact is arranged on the lower end of the slide block, a lower chute is formed in a position below the electric contact in a bottom wall of the sliding cavity, and a sliding plate is installed in the lower chute in the up and down sliding manner.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding device. Background technique [0002] The welding machine is often used in the field of electric welding. The welding machine needs to be powered and plugged in before it can be used. Due to the high voltage required for the electric welding machine to work, the socket is directly charged during the plugging process, and it is affected by unstable factors in manual plugging. It is very easy to generate arcs, which may induce electric shock accidents, and there is a great potential safety hazard. At the same time, the power supply cable used by the welding machine has a large weight, and the plug connector setting mode of the welding machine is simple and does not have any locking structure. , Under the influence of factors such as self-weight or pulling of the power supply cable, it is easy to cause the plug connector to loosen, resulting in power supply interruption, w...

[0002] The welding machine is often used in the field of electric welding. The welding machine needs to be powered and plugged in before it can be used. Due to the high voltage required for the electric welding machine to work, the socket is directly charged during the plugging process, and it is affected by unstable factors in manual plugging. It is very easy to generate arcs, which may induce electric shock accidents, and there is a great potential safety hazard. At the same time, the power supply cable used by the welding machine has a large weight, and the plug connector setting mode of the welding machine is simple and does not have any locking structure. , when the power supply cable is affected by factors such as its own weight or pulling, it is easy to cause the plug connector to loosen, resulting in power supply interruption, which brings great inconvenience to the normal use of the welding machine
