A kind of universal plug for welding torch with rotating closing device

Abstract

The invention relates to a universal welding gun plug provided with a rotary closing device. The plug comprises a casing, wherein the left side of the casing is fixedly connected with a direction jack for connecting a power connecting line, the outer side wall of the direction jack is sleeved with a rotary casing pipe, a round rotary disc is arranged on the right side surface in the direction jack, a plurality of chutes are formed in positions, corresponding to the rotary disc, of the outer side wall of the direction jack, and a plurality of connecting supports are fixedly connected in positions, corresponding to the chutes, of the inner side wall of the rotary casing pipe. According to the universal welding gun plug provided with the rotary closing device, the rotary casing pipe drives the rotary disc to rotate on the right side wall in the direction jack to control opening and closing of connecting holes, then the rotary casing pipe is fixed by a fixing sleeve, the connection firmness during usage is greatly improved, the safety of the connecting end is improved, blockage of the connecting holes and rusting of inner sheet metal are prevented when the plug is not used, and the service life of the universal plug is greatly prolonged.

Description

technical field [0001] The invention relates to a universal plug for a welding torch with a rotary closure device. Background technique [0002] At present, the universal plugs on the market are widely used, and the 14-core plug can be applied to various welding torch models with complex circuits, which integrates functions such as protection line control, leakage control, low voltage protection control and low current protection control, etc., but the traditional The 14-core plug has a simple structure. The power cable on the left side is mainly fixed by tightening the gap. This can only deal with cables with a thicker diameter, but cannot fix cables with a smaller diameter, resulting in poor versatility. When the connection hole is easily blocked by dust, the internal metal contact piece is rusted. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the above existing problems, a universal plug for welding...
