Novel welding device

Abstract

A novel welding device comprises a distribution box and an electric connecting head connected with a welding machine. At least one set of electric connecting seats are arranged in the distribution boxand separated by separating plates up and down. An adapter hole with a rightward through opening is formed in each electric connecting seat. An adapter part is rotationally installed in each adapterhole. Inserting grooves penetrating through each adapter part from left to right are formed in the adapter part up and down equally. Electric connecting sheets are fixedly installed in the inserting grooves. An abrasion-resistant sheet is fixedly installed in the middle of the left end surface of each adapter part, and an empty hole is formed in the left end surface of each abrasion-resistant sheet. An annular connecting groove is formed in the part, located at the left end of the corresponding adapter hole, of each electric connecting seat. A middle groove is formed in the middle of the leftend of each annular connecting groove. A sliding connecting part is installed in each middle groove in a left-right sliding mode. An inserting pin is fixedly installed in the middle of the right end surface of each sliding connecting part. Crescent grooves are formed in the end wall of each annular connecting groove and located in the rear upper direction and front lower direction of the corresponding sliding connecting part. Pushing grooves extending up and down are formed in the end wall of each annular connecting groove up and down equally and communicate with the crescent grooves. Electricconnecting blocks are installed in the pushing grooves in a sliding connecting mode.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a novel welding device. Background technique [0002] Welding machines are often used in the field of electric welding. Welding machines need to be powered and plugged in before they can be used. Because welding machines require high voltage, they are generally equipped with power distribution boxes. However, existing power distribution boxes are generally directly connected to the mains. Moreover, the conductive parts of the internal electric connection seat are set relatively outside, which can easily cause electric shock accidents under human careless touch, and there is a large safety hazard. At the same time, the power supply cable used by the welding machine has a large weight , and the electric welding machine does not set any locking structure during the plugging process.

[0002] Welding machines are often used in the field of electric welding. Welding machines need to be powered and plugged in before they can be used. Because welding machines require high voltage, they are generally equipped with power distribution boxes. However, existing power distribution boxes are generally directly connected to the mains. Moreover, the conductive parts of the internal electric connection seat are set relatively outside, which can easily cause electric shock accidents under human careless touch, and there is a large safety hazard. At the same time, the power supply cable used by the welding machine has a large weight , and the electric welding machine does not set any locking structure during the plugging process. Under the influence of the power supply cable's own weight or pulling and other factors, it is very easy to cause the electric joint to loosen, resulting in power supply interruption, which brings extreme damage to the normal use of the welding machine. big inconvenience
