Abstract

The utility model relates to technical protective equipment for electric arc manual welding. The purpose of the utility model is to maximize comfort when using the welder's mask. This goal is achieved by the presence on the front wall of the mask of a rigidly fixed frame with an opening sash equipped with a package of protective glasses. The mask contains a frame with sides on the front wall and a hinged sash in the upper part of the frame. The shutter also has sides opposite the sides of the frame, which go one behind the other. The beads prevent glare from entering the mask. The shutter is equipped with a package of safety glasses. To the casement on a parallel main axis, on the inside of the mask levers are fixed and linked to the casement through sockets on the casement. The levers slide freely in the slots. The main axis has levers connected to the bracket along the sides of the mask. The staple has a nest for the chin, transmitting force when opening the sash. The levers for transmitting force are additionally connected to the return springs fixed to the mask body, which allows closing of the sash. New in the utility model is a frame with sides and a sash with sides equipped with a system of levers on the main axis transmitting forces, return springs and a bracket with a chin slot.

Description

The utility model relates to technical protective equipment when performing manual arc welding, both from hard radiation and from splashes of molten metal. The purpose of the mask is to protect the face and organs of vision.

The well-known design of the mask welder GOST. 12.4.035.71. The mask consists of a body, a headband and a package of protective glasses on the front wall rigidly fixed to the body.

The disadvantage is that when using it, you need to raise or lower the mask with your hand to aim the electrode at the seam being applied, from which orientation is lost, plus unnecessary movements and loss of time.

The proposed model consists of a body - 1 with a headband - 2. A frame - 3 is rigidly fixed to the front wall, 4 with external edges, a sash - 6 with inside edges - 7 and a safety glass package - 8 is fastened on hinges - 5. The sash is tied from the mask side on a parallel axis - 9 levers opening and closing the sash - 10 sliding relative to the sash in the slots - 11.
