A kind of protective goggles and mask assembly

Abstract

The invention discloses a protective goggle and face mask assembly. The inner side of the light-transmitting plate is slidably provided with a goggle plate, a first extruding block and a sliding bar which are sequentially fixedly connected, and the sliding bar is fixedly connected with a plurality of second extruding bars at intervals. block, the lighting circuit includes a lighting lamp and a first switch assembly, the cleaning circuit includes an electromagnet and a second switch assembly, and the cleaning assembly includes a cleaning box and an electromagnet fixedly connected in sequence, an elastic pull rod, a magnetic push plate and A cleaning plate, the cleaning block includes a fixedly connected pole, an elastic extrusion block and a limit block that restricts the one-way rotation of the pole. In use of the present invention, the weldment is illuminated by a lighting lamp, and a plurality of first The cooperating arrangement of the second extruding block and the second switch assembly makes the cleaning plate protrude multiple times to clean the light-transmitting plate, and also through the co-setting of the pole, the limit block and the elastic extruding block, it is ensured that the light-transmitting plate While cleaning the effect, reduce the pressure on the light-transmitting board.

Description

technical field [0001] The invention relates to the technical field of welding protective equipment, in particular to a protective goggle and face shield assembly. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials by heating and high temperature. During the welding process, glare and fine particles will be produced, which will cause damage to the health of welders. Therefore, welders will wear protective goggles to protect their eyes when welding. Protective goggles generally choose special glass with extremely weak light transmission such as cobalt glass to filter strong light, but after wearing protective goggles, it is difficult for welders to accurately find the welding position through cobalt glass, so welders need to take off the protective goggles to determine the welding position, and then Wear protective goggles for welding, so that the welding perso...

AI Technical Summary

Problems solved by technology

[0004] But still there is bigger defect in prior art, as: 1, the movable cobalt glass of above-mentioned technology is positioned at the outside of transparent eye mask, and the smog that produces in welding process is easy to be attached on the movable cobalt glass, influences the line of sight of welder, causes welding operation Adverse effects, and the movable cobalt glass is easily damaged by external impact on the outside, and the replacement of the movable cobalt glass will increase the production cost; 2. In the case of insufficient light, such as when the welding position is at the corner, it is difficult for the staff to accurately determine through the transparent goggles Welding position, which adversely affects the welding operation
