Abstract

The invention discloses a safety helmet. The safety helmet comprises a helmet shell (1), an elastic buffer layer (2) and an inner layer (3), wherein a helmet brim (7) is arranged on the helmet shell (1), a bulge (4) is arranged on the top of the helmet shell (1), a first air hole (5) is formed at the joint of the bulge (4) and the top of the helmet shell (1), a second air hole (6) is formed in the side part of the edge of the helmet shell (1), and a protective cover (8) is arranged on the helmet shell (1); the elastic buffer layer (2) is made of silicone rubber, and massage bulges (9) are arranged on the elastic buffer layer (2); and the inner layer (3) is in an annular structure. The safety helmet is high in safety performance, good in protective effect, and rapid in heat dissipation, and can massage the head.

Description

technical field [0001] The invention relates to the technical field of electric maintenance safety tools, in particular to a safety helmet. Background technique [0002] At present, electric maintenance personnel must wear safety helmets when working, but the safety helmets have poor ventilation performance in order to ensure safety strength. When the staff wear safety helmets to work, a heat accumulation area will be formed inside the safety helmet, and the heat cannot be dissipated. Especially when working in the field in summer, the wearer feels that the head is very hot and is prone to heatstroke; in addition, sweat flows down the head and easily flows into the eyes, affecting sight. The structure of the safety helmet in the prior art is that the outer layer is mostly a plastic shell, the shell is very hard, and there is a lining layer inside. When the lining layer is designed thicker, it is not easy to dissipate heat. Comfortable. [0003] Chinese patent CN202283052U ...
