AI Technical Summary
Existing fire helmet visors are prone to coming loose after repeated use, are complicated to disassemble and maintain, and require additional welding visors or removal of the helmet during welding operations, making them inconvenient to use.
The mask slide rail structure, which uses an interference fit between a sliding boss and a slide groove, combined with a drive assembly and a spring limit plate, enables stable installation of the transparent mask and allows welding masks to be installed without removing the helmet.
It achieves stable sliding of the transparent mask, preventing it from coming loose, simplifying the disassembly and maintenance process, and eliminating the need to wear an additional welding mask during welding, making it more convenient to use.
