Abstract

The invention relates to a safety helmet, in particular to a safety helmet for a tunnel construction worker. In order to solve the technical problems, the safety helmet which multiply protects a humanhead, is high in safety and has an illumination function is provided. The safety helmet comprises a top roof, a first rotating frame, a baffle, a supporting rod, an illumination lamp, a first nut, ahead cover, a fixing rope, a buckle and the like, wherein a circular groove is formed in the top of the head cover, an annular groove is formed in the middle of the outer side of the head cover, an annular hole is formed in the top wall of the annular groove, and rotating blocks are symmetrically arranged in the annular groove left and right. By means of the safety helmet, the effects of multiplyprotecting the human head, being high in safety and having an illumination function are achieved; by means of the top roof and the head cover, the safety helmet multiply protects the human head; meanwhile, by means of a swing shielding plate, the protection range is widened, and safety is high; by arranging the illumination lamp, light is provided for tunnel construction, and functions are diversified.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a safety helmet for tunnel construction workers. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. [0003] During the tunnel construction process, the construction object is above the person, and the sand or gravel generated during the construction will often fall due to excavation. If the head of the person is not protected, it will cause serious medical accidents. To protect the head of the person, Mainly rely on safety helmets. Today's safety helmets only have one layer of protective layer, which has poor protection effect on the human head, low safety, and single function, which cannot be used for lighting. Therefore, it is urgent to develop a multi- Hard hat for tunnel construction workers with high protection, safety and lighting functions. Contents of the invention [0004] (1) Technical proble...
