What is the role of the construction safety helmet?
The helmet has shock absorption property, puncture resistance, lateral rigidity, electrical insulation and flame retardance. Its shell: bear a shock and separate the falling object from the human body. Cap: to hold a helmet in a definite position on the head. Top band: scatter the impact, keep the cap floating, so as to disperse the impact force. Rear band: locking device for head band. The lower jaw: helps maintain the helmet's position and position. Sweat absorption: sweat absorption. Cushion: reduce impact when impact occurs.
The safety helmet consists of a cap shell, a cap lining, a lower cheek belt and a back hoop. The cap shell is hemispherical, firm and smooth, and has a certain elasticity, the impact of the impact and the puncture kinetic energy are mainly borne by the cap shell. There is a certain space between the cap and the cap to buffer and disperse the instantaneous impact force so as to avoid or reduce the direct injury to the head.
Construction safety helmet is a kind of protective equipment for preventing impact damage from the head.
