Technical Field

[0001] The utility model belongs to the technical field of electric welding protective equipment, and more specifically, particularly relates to a protective helmet for preventing occupational diseases of electric eye. Background Art

[0002] In industry, when electric welding or gas welding is performed, due to the lack of protective glasses or protective masks, or the poor protective effect of the protective glasses, a large amount of ultraviolet rays are often emitted from the arc during electric welding, causing eye damage. Currently, most protective equipment for preventing this occupational disease, such as welding helmets, are hand-held, with lenses provided on the masks. Different masks are used according to different welding operations. For example, when electric welding, a No. 7 mask is used, which can effectively block strong ultraviolet rays. For gas welding or gas cutting, ordinary sunglasses can be used.

[0003] The existing announcement number CN205947917U discloses a helmet for preventing electro-photographic occupational diseases. Although it adopts a transparent flat lens, the extension of the arc angle can effectively expand the field of vision, closed connection, strict protection, and increased safety; it adopts a light-proof lens to protect against visible light, infrared, ultraviolet, laser and other radiation light, is easy to replace, easy to repair and maintain, and can prevent the splashing of liquids and solids.

[0004] Based on the above, the inventors have found the following problems: However, when performing electric welding operations, due to the different working environments, some are indoors and some are outdoors, and the different weather causes different outdoor brightness, and the light-blocking effect of this type of helmet is fixed. If it is used in a darker or brighter environment, it will cause some discomfort. For example, in a darker environment, it is difficult to see the position that needs to be welded through the helmet, and the mask needs to be repeatedly flipped, which is inconvenient to use.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a protective helmet for preventing electro-photographic occupational diseases is provided, in order to achieve a more practical purpose. Utility Model Content
