Safe welding device

Abstract

The invention discloses a safe welding device. The safe welding device comprises a frame body and an electric connector inserted in the frame body for matching connection, wherein fixed plates are fixedly mounted at the lower end parts of the left side and the right side of the frame body; a fixed hole which runs through up and down is formed in each fixed plate; a clamping groove is formed in the frame body, and an opening of the clamping groove is forward; an inserting groove communicating with the clamping groove is formed in the rear end part of the clamping groove; an electric connection groove communicating with the inserting groove is formed in the rear end part of the inserting groove; control grooves communicating with the inserting groove are symmetrically formed in the frame body on the left side and the right side of the electric connection groove; sealing devices for sealing the electric connection groove are further symmetrically formed in the frame body on the left side and the right side of the electric connection groove; a sliding groove is further formed in the frame body; and a pipe barrel cavity extending backwards is arranged at the middle part of the rear end part of the sliding groove. The safe welding device is simple in structure, safe and stable in power supply and safe and reliable in overall operation, the accidents of electric shocks in daily life are effectively reduced, and the device is applicable for popularization and application.

Description

technical field [0001] The invention relates to the field of welding, in particular to a safe welding device. Background technique [0002] Welding is a manufacturing process and technology for joining metal or other thermoplastic materials by means of heating, high temperature or high pressure. It is widely used nowadays. Before using the welding machine, it is necessary to power on the welding machine so that the welding machine can operate normally. In places where many welding machines are used, a power supply frame is usually provided to supply power to the welding machine, but the electrical connection groove in the existing power supply frame is always in a power-on state, and the electrical connection groove is not provided with a coverable protective piece. It is easy to cause electric shock hazard when connecting the electric head. In addition, because the electric connection slot is not equipped with a lock for the electric connection head, if someone accidentally...

[0002] Welding is a manufacturing process and technology for joining metal or other thermoplastic materials by means of heating, high temperature or high pressure. It is widely used nowadays. Before using the welding machine, it is necessary to power on the welding machine so that the welding machine can operate normally. In places where many welding machines are used, a power supply frame is usually provided to supply power to the welding machine, but the electrical connection groove in the existing power supply frame is always in a power-on state, and the electrical connection groove is not provided with a coverable protective piece. It is easy to cause electric shock hazard when connecting the electric head. In addition, since the electric connection slot is not equipped with a lock for the electric connection head, if someone accidentally kicks and hits the power cord by mistake, it will cause a sudden power failure of the welding machine.
