Abstract

The invention discloses a head-mounted welding mask which comprises a mask shell, a head-mounted mechanism and an overturning device. The overturning device comprises a rotating knob, a linkage mechanism and a base, the rotating knob is connected with the mask shell, the linkage mechanism is connected with the rotating knob, the base is connected with the head-mounted mechanism, the linkage mechanism is arranged on the base, the rotating knob drives the linkage mechanism to reciprocate in a curve when being moved, so that the mask shell is overturned relative to the head-mounted mechanism, andthe gravity center of the overturned mask shell moves into a set range taking a gravity line of the gravity center of the head-mounted mechanism as a standard. The head-mounted welding mask is the overturning device, the overturning device changes the gravity center position of the mask shell through movement of the linkage mechanism, so that the gravity center of the overturned mask shell is moved into the set range taking the gravity line of the gravity center of the head-mounted mechanism as the standard, and the compressive feeling of the head of a welder due to the overturned mask shellis relieved.

Description

technical field [0001] The invention relates to the technical field of electric welding protection, in particular to a head-mounted welding mask. Background technique [0002] Welding arcs are often generated during metal welding. Welding arcs are a gas discharge phenomenon that occurs between the electrode and the weldment. It contains a large amount of high-intensity visible light, infrared rays, and ultraviolet rays. Optical radiation can damage welders' eyes. [0003] Welding masks are used to help welders protect against occupational hazards from welding, and to help them protect their eyes and accurately position and weld efficiently during the welding process. A common head-mounted welding mask includes a mask shell and a headband mounted on the mask shell for the welder to wear. During the welding process, the welder often turns over the mask shell to check the welding effect. [0004] In the related art, when the mask shell is turned over, the mask shell rotates a...
