Abstract

The invention discloses a welding mask. The welding mask comprises a welding cap, an eye guard disposed at the front side of the welding cap, a filter disposed on the eye guard, and a head band assembly disposed in the welding cap, wherein the welding cap is movably connected with the eye guard; an eye guard adjusting device disposed on side portions of the welding cap and the eye guard; the eye guard adjusting device comprises an eye guard limiting disc fixed to one side of the front end of the welding cap, and an adjusting handle fixed to the eye guard and located at the same side with the eye guard limiting disc; a plurality of limiting teeth in divergent distribution are formed on the eye guard limiting disc; and the adjusting handle has one end embedded into the limiting teeth, and the other end serving as an operating end of the adjusting handle. The welding cap is capable of reducing the harm of smoke dust, toxic gas and noise to the body of the welding personnel to a large extent, and can be firmly worn on the head of the welding personnel; and the labor intensity in the welding process is reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to a welding mask. Background technique [0002] With the continuous development of science and technology, welding technology has been widely used in automobiles, aerospace, construction, bridges, etc., so a large number of front-line workers are engaged in welding. Welding is a labor-intensive job. The smoke and toxic gases produced during the welding operation will strongly stimulate the human respiratory tract and lungs, and in severe cases, welders will suffer from pneumoconiosis. The noise produced at the same time will cause hearing impairment. And central nervous system and blood system disorders, etc., resulting in the overall decline in the physical function of technicians who have been engaged in welding for a long time. The welding helmets currently used in the market lack protection for the ears, and the gas fluidity inside the welding helmet is poor, so that they cannot effectively protect against the hazard...
