Welding mask

Abstract

The invention discloses a welding mask and relates to the field of mechanical accessories. The welding mask comprises a mask body, goggles are arranged on the mask body, and a movable binding band is arranged on the mask body, so that the mask can be fixed at the head during electrowelding and does not fall down due to gravity action, convenience is brought to two hands to hold for electrowelding, welding quality is improved, and expense for making a welding helmet connected with the mask can be saved. The goggles include spectacles and an ink-color convex lens, the spectacles protect eyes from being hit by splashing objects, the ink-color convex lens expands visible field and filters arc light, and is inserted, and lenses can be replaced according to own needs; a protecting mask is arranged below the goggles, so that smoothness in breathing is realized, and respiratory gas is stopped from ascending to mist the goggles; a filtering chip is arranged in the protecting mask, so that protection from toxic air generated during electrowelding is realized; a lining face is arranged on the inner side of the mask body, so that a buffering space is formed between the mask and skin, and wearing friction force and comfortability of the mask are improved.

Description

technical field [0001] The invention relates to the field of mechanical accessories, in particular to an electric welding mask. Background technique [0002] Electric welding is a mechanical processing method that uses a large amount of current to pass through the poles at a certain distance, that is, the arc phenomenon generated at the end point generates high heat, and makes the metal parts or materials at the hot spot welded to each other. During the construction process of electric welding, there will be Intense arc and strong light damage, and splashing of high-temperature hot solder or metal chips, so if the welder performs the above-mentioned electric welding construction, he must wear a welding mask and use the goggles on the welding mask to protect the eyes so that the eyes do not It will be damaged by strong light, and at the same time, the face will not be burnt by spraying solder and metal shavings, so as to maintain the safety of construction. Patent No. 2011201...

[0002] Electric welding is a mechanical processing method that uses a large amount of current to pass through the poles at a certain distance, that is, the arc phenomenon generated at the end point generates high heat, and makes the metal parts or materials at the hot spot welded to each other. During the construction process of electric welding, there will be Intense arc and strong light damage, and splashing of high-temperature hot solder or metal chips, so if the welder performs the above-mentioned electric welding construction, he must wear a welding mask and use the goggles on the welding mask to protect the eyes so that the eyes do not It will be damaged by strong light, and at the same time, the face will not be burnt by spraying solder and metal shavings, so as to maintain the safety of construction. Patent No. 201120175680.2 discloses an electric welding mask, which includes a mask shell, a shell The upper view mirror frame is set. The view mirror frame is composed of a main body installed on the housing and an auxiliary body with a shrapnel snap ring. The left and right edges of the auxiliary body are provided with extruded shrapnel. When the main body and the auxiliary body are combined by the shrapnel snap ring, the viewing The mirror glass is fixed between the main body and the auxiliary body by extruding the shrapnel. The key point of the mask design is to clamp the mirror glass through the dual functions of the shrapnel snap ring and the extruding shrapnel, so that it will not be loose when installed on the mask, and the structure is simple. It is easy to replace, but such welding masks cannot solve the problems of inconvenient operation of hand-held welding masks, goggles cannot be replaced according to needs, and cannot protect against toxic air generated during electric welding.
