Abstract

The invention discloses a welding mask with an adjustable visual area needing to be enlarged during turning, and relates to the technical field of welding masks. The visual area is convenient to adjust; the welding mask specifically comprises a main body and an arc-shaped lens, the arc-shaped lens is detachably clamped to the outer wall of one side of the main body in an embedded mode through twosymmetrical adjusting mechanisms, each adjusting mechanism comprises an elastic shielding pad and a sliding plate, and the outer walls of one sides of the two elastic shielding pads are fixed to the inner walls of the two sides of the main body through screws correspondingly; the outer wall of one side of the sliding plate is fixed to the outer wall of the other sides of the elastic shielding padsthrough screws. By arranging the sliding plate, the elastic shielding pads and other structures, the size of the visual area of the arc-shaped lens can be adjusted by controlling the sliding plate toslide in the groove according to needs, the practicability is improved, and the arc-shaped lens and the inner wall of the main body form a clamping structure through the elastic shielding pads and the sliding plate, so that the arc-shaped lens can be quickly disassembled, and replacement and maintenance are faciliated.

Description

technical field [0001] The invention relates to the technical field of welding masks, in particular to a welding mask that needs to turn and enlarge an adjustable viewing area. Background technique [0002] Welding masks refer to the tools used to protect the safety of operators during welding and cutting operations, avoiding the damage of arc radiation to the eyes and faces of welders; although most welding masks can meet certain welding needs at present, due to their fixed size, they are not used in At the same time, the size of the viewing area cannot be adjusted according to the actual situation, and it is inconvenient to disassemble and assemble the mirror surface, which is not conducive to maintenance. [0003] After retrieval, the Chinese patent application number is CN201320231297.3, which discloses a welding mask, including a cover body, a head ring, sunglasses, a pin hook mechanism and a drawstring; the head ring is fixed in the cover body; the front end of the cov...
