Description

A cool type work safety helmet

technical field

The utility model relates to the technical field of safety helmets, in particular to a cool-type work safety helmet.

Background technique

A helmet is a protective device that prevents impact objects from hurting the head. Consists of cap shell, cap lining, lower cheek straps and rear hoop. When the worker's head is impacted by a falling object, the helmet shell and cap lining are used to decompose the impact force to the entire area of the cranium in an instant. The structural damage will absorb most of the impact force, so that the final impact force on the head of the personnel is reduced to below 4900N, thus protecting the head of the operator. The shell material of the helmet plays an important role in the overall resistance of the helmet.

The utility model patent with the authorization announcement number CN207084243U in the prior art discloses a multifunctional safety protection safety helmet, which includes a safety helmet shell and a safety helmet lining. A rubber block is fixed at the middle position between the shell and the inner lining of the safety helmet, and four first buffer outer cylinders arranged vertically are fixed at the middle position of the bottom end of the safety helmet shell, and the four first buffer outer cylinders are located outside the rubber block. Four vertically arranged first buffer inner cylinders are fixed at the middle position of the top of the inner lining of the safety helmet, the outer side wall of the first buffer inner cylinder is slidably connected to the inner side wall of the first buffer outer cylinder, and the surrounding inner side walls of the safety helmet shell are Four horizontally arranged second buffer outer cylinders are fixed.
