Multifunctional welding mask

Abstract

The invention discloses a multifunctional welding mask. The multifunctional welding mask comprises a main body, wherein a helmet cavity which is provided with a downward opening and penetrates through front and back is formed in the main body; rotary cavities which are provided with openings towards front and back sides are formed in front and back sides of the main body; an air inlet which penetrates through front and back is formed in the upper side in the main body; one wall, close to the air inlet, of each rotary cavity is in rotary connection with a rotary shaft; one end, far away from the air inlet, of each rotary shaft is fixedly connected with a rotary plate; and a torsion spring is fixedly connected between one end face, close to the air inlet, of each rotary plate and one wall, close to the air inlet, of each rotary cavity. According to the multifunctional welding mask disclosed by the invention, a photographed picture can be displayed on a display screen in the mask through a camera, and light rays generated in a direct-vision welding process can be prevented from being injured to eyes; meanwhile, the device can be used for adjusting the brightness of the picture seen by the camera and effectively helping workers to observe better; and meanwhile, the device can also be used for preventing the workers from breathing smoke dust generated in the welding process and protecting the human health of the workers.

Description

technical field [0001] The invention relates to the field of welding, in particular to a multifunctional welding mask. Background technique [0002] During the welding process, the welding light will cause great damage to the eyes of the staff. Even through the mask observation, the damage can only be reduced but not completely offset. At the same time, during the welding process, the solder joints will produce harmful smoke. The mask cannot isolate the smoke and dust and can only block the welding light. The smoke and dust inhaled by the staff will easily affect the health of the staff. At the same time, the general mask cannot freely adjust the shading degree of the dark lens. A multifunctional welding mask described in the present invention can solve the above problems. Contents of the invention [0003] In order to solve the above problems, this example designs a multifunctional welding mask. The multifunctional welding mask of this example includes a main body. The ...
