Description

A kind of multifunctional safety helmet for electrician

technical field

The utility model relates to the field of electric safety, in particular to a multifunctional safety helmet for electricians.

Background technique

The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head, and it is a protective product to prevent impact objects from hurting the head. Consists of shell, lining, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets. When the worker's head is impacted by falling objects, the helmet shell and cap liner are used to first decompose the impact force to the entire area of the skull, and then use the elastic deformation, plastic deformation and allowable The structural damage of the machine absorbs most of the impact force, reducing the final impact force on the personnel's head to below 4900N, thereby protecting the operator's head. The shell material of the helmet plays an important role in the overall impact resistance of the helmet.

General safety helmets only protect the head and prevent injuries due to impact, but cannot actively predict the danger, and have a single function, which cannot meet people's needs.
