What are the basic features of a safety helmet?
Wearing height: reflects the height difference between the forehead and the head. It interferes with the eyes, ears, and the wearer. A cap with a small helmet separating from the forehead part. The fastening parts are not closed, and they can not be guaranteed to have a certain position and position on the head. Vertical spacing: reflects the gap between the inside of the cap and the top of the head. Too small, poorly ventilated, too large, the center of gravity of the cap rises, causing the helmet to be unstable on the head.
Main structure of safety helmetShell: to withstand a shock to separate a 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 function of safety helmet 1, shock resistance.2 、 penetration resistance.3 、 low temperature resistance.4, combustion resistance.5 、 electrical insulation performance.6, lateral rigidity.
