A safe connection device for electric welding machine

Abstract

The invention discloses a safe connecting device for an electric welding machine. The safe connecting device comprises a wall body and a frame base, wherein the frame base is arranged in the wall body; a cavity is formed in the inner bottom of the frame base; a sliding part is arranged in the cavity; a control area is arranged in the outer wall of the left side of the sliding part; a placement groove is formed in the position, on the right side of the control area, of the sliding part; a first hollow cavity is formed in the position, on the right side of the placement groove, of the sliding part; a first baffle is arranged between the first hollow cavity and the placement groove; a second hollow cavity is formed in the position, above the first hollow cavity, of the sliding part; a first baffle is arranged in the second hollow cavity; a boss is arranged in the position, above the first baffle, of the second hollow cavity; and protruding blocks are arranged on the tops of the two sides of the boss; magnets are arranged in the bottoms of the protruding blocks; electromagnetic coil devices are arranged at the positions, corresponding to the magnets, of the top of the first baffle; first pressure springs are arranged between the electromagnetic coil devices and the magnets; and the bottom of the boss penetrates through the first baffle. According to the safe connecting device, the structure is simple, the operation is convenient, the wiring requirements of different distances can be met, and the operation of taking up wires can be automatically realized, the occupied area is small, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a safe connection device for electric welding machines. Background technique [0002] At present, electric welding machines are widely used in some electric welding factories. During welding, some welding objects are large and difficult to move, so it is necessary to move the electric welding machine to the welding position. However, the length of the connecting wires of the existing electric welding machines is limited. The wires are short and difficult to plug into the power supply socket. In the existing one or more plug boards are generally used to lengthen the connection, which makes the operation cumbersome and makes it more difficult to take and discharge the wires. At the same time, because there are many plug connectors, artificial Accidental trampling can easily lead to electric shock accidents, and there is a great potential safety hazard.
