Anti-scalding welding clamp

Abstract

The invention provides an anti-scalding welding clamp. The anti-scalding welding clamp comprises an electric conductor, an insulated handle, an insulated heat isolation cushion block, gasket coupling screws and handle coupling screws. At least one first threaded hole is formed in the lower end face of the electric conductor. The insulated handle is arranged on the electric conductor in a sleeving mode and is provided with at least one first through hole. The insulated heat isolation cushion block is provided with second through holes and second threaded holes. The gasket coupling screws penetrate through the second through holes and are connected with the first threaded holes, so that the insulated heat isolation cushion block is fixed to the electric conductor. The handle coupling screws penetrate through the first through holes and are connected with the second threaded holes, so that the insulated handle and the insulated heat isolation cushion block are fixedly connected. The anti-scalding welding clamp has the beneficial effects that a mounting structure among the insulated heat isolation cushion block, the electric conductor and the insulated handle is optimized, and therefore reliability of the welding clamp is improved, the heat insulating property can be improved obviously, and the probability of electric leakage is lowered.

Description

technical field [0001] The invention belongs to the technical field of electric welding tongs, and relates to an anti-scald electric welding tongs. Background technique [0002] Welding pliers are tools for electric welding. They have two handles and are shaped like pliers. They are mainly composed of pliers mouth, upper handle, spring, connecting frame, insulating handle and conductors installed in the insulating handle. The jaws clamp the electrode, and the conductor of the welding tongs transmits a large amount of current to the electrode, and an arc is generated between the electrode and the welding base material to melt the electrode to achieve welding. [0003] The conductors of the existing electric welding tongs are basically made of copper materials, and their shapes are elongated. The rear end of the elongated conductors is provided with a fixing ring for connecting and fixing the connecting plate of the power cable. The front end of the body is the lower jaw of t...

Problems solved by technology

[0005] But although the above-mentioned electric welding pliers have certain anti-scalding effect, the installation structure between the heat insulation block and the insulating handle is not reliable enough, and the conductor fixing screw not only easily transfers the heat of the conductor to the insulating handle, but also has certain Leakage is dangerous, and the heat insulation performance needs to be further improved
