Electric welding protecting mask

Abstract

The invention discloses an electric welding protecting mask. The electric welding protecting mask comprises a face mask and a mandible mask, wherein the mandible mask is arranged below the face mask and is integrally formed with the face mask; an observation area is arranged at the upper part of the face mask; a photoreceptor is arranged above the observation area; colorless transparent glass is arranged in the observation area; a glass bin is arranged below the observation area in the face mask; a plurality of pieces of colored glass are arranged in the glass bin; a driving motor is arranged above the observation area in the face mask; a connecting rod is arranged below the driving motor; one end of the connecting rod is connected with the driving motor; the other end of the connecting rod is connected with the colored glass. By arrangement of the photoreceptor on the protecting mask, the protecting mask judges the intensity of light, and drives the motor to pull up the colored glass and to block the observation area according to the intensity of the judged light, so as to achieve the optimum observation effect.

Description

technical field [0001] The invention relates to the field of electric welding technology, in particular to an electric welding protective mask. Background technique [0002] In the process of manual electric welding, glare is usually produced, so the operator needs to wear a protective cover. Traditional electric welding protective covers usually set a piece of dark glass in the observation area to protect the eyes. However, before the formal welding The welding torch needs to be aimed at the specific position to be welded. However, since the welding has not started yet, there is no bright light, so it is impossible to observe through the dark glass in the observation area at this time, and the protective cover must be removed for alignment. It is difficult to ensure that the alignment does not shift when the protective cover is put on manually again. Contents of the invention [0003] In view of the above problems, the present invention provides an electric welding prote...
