Heat dissipation construction hard hat

Abstract

The invention relates to a heat radiating building safety helmet. The heat radiating building safety helmet comprises an outer housing made of a hard material and an inner housing made of an elastic expansion material. A protection cavity in a flat long strip shape is fixed and abutted close to the inner side surface of the outer housing. The protection cavity is internally provided with a piston block which can slide along the inner wall of the protection cavity. The inner side surface of the inner housing is fixed and abutted with a heat radiation cavity in a bowl shape. The heat radiation cavity is communicated with two ends of the protection cavity through two liquid guiding pipes. The heat radiation cavity and the protection cavity are filled with cooling liquid. The lower edge of the inner housing is symmetrically provided with two semicircular adaptive hoops. Each adaptive hoop is fixed by a pressure spring which is installed on the inner side surface of the outer housing. The axis of each pressure spring extends along the radial direction of the outer housing. The safety helmet is novel in structure and relatively light in texture, and fits scalp, and has good heat radiation effect while having security guarantee.

Description

Technical field [0001] The invention relates to a construction safety protective gear, in particular, a safety helmet. Background technique [0002] In building construction, in order to ensure the safety of life, workers need to wear safety protective gear, of which the helmet is the most basic protective gear, which can effectively prevent falling objects from high altitude from hurting the fragile head; but there are many tasks in actual construction Personnel are reluctant to wear helmets, mainly because they are not comfortable to wear. Today’s helmets are of high quality, which puts more pressure on the head when worn, and is inconvenient to carry. People’s head sizes are different, so many people don’t fit the scalp and the cap shell when wearing it, and the head feels uncomfortable. The existing helmets have poor heat dissipation and ventilation effects. After wearing for a period of time, the scalp will get warm and sweat. Not comfortable. Summary of the invention [00...
