Safety helmet with high-temperature-resistant structure and convenient to disassemble

Abstract

The invention relates to the technical field of safety helmets, and discloses a safety helmet with a high-temperature-resistant structure and convenient to disassemble, the safety helmet comprises a safety helmet body, an annular groove is sectioned in the outer wall of the bottom end of the safety helmet body, and a fixing ring is fixedly connected to the middle wall surface of the annular groove in the bottom end of the safety helmet body; movable grooves are formed in the positions, corresponding to the middles of the sliding plates, of the outer wall of the fixing ring, center shafts are fixedly connected to the inner walls of the side faces of the movable grooves, the outer walls of the center shafts are sleeved with rotating rings, push plates are fixedly connected to the bottom ends of the rotating rings, connecting rods are fixedly connected to the top ends of the rotating rings, and fin radiators are fixedly connected to the ends, away from the rotating rings, of the connecting rods. When the safety helmet body is in a high-temperature state, a wearer turns over the fin radiator out through simple operation of pulling the sliding ring, then the fin radiator makes contact with the outer wall of the safety helmet body, and heat dissipation and cooling are conducted on the safety helmet body through the heat dissipation function of the fin radiator. The influence on the work and the body of a wearer caused by high-temperature accumulation of the safety helmet body is avoided.

Description

technical field [0001] The invention relates to the technical field of safety helmets, in particular to a safety helmet with a high temperature resistant structure that is easy to disassemble. Background technique [0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. The safety helmet is composed of a cap shell, a cap lining, a chin strap and accessories. The safety helmet not only plays a protective role, but also covers the wearer's head, which causes the safety helmet to be exposed to sunlight for a long time in summer, and Absorbs and accumulates the heat of the sun, resulting in high temperature in the area of ​​the wearer's head, affecting the wearer's work, etc., and in severe cases, the wearer may suffer from heat stroke and other problems, while the existing helmets have a single heat dissipation function and cannot be controlled at will. In winter, due to the heat dissipation funct...

AI Technical Summary

Problems solved by technology

The helmet is composed of the cap shell, cap liner, chin strap and accessories. The helmet not only plays a protective role, but also plays a role in covering the wearer's head. As a result, the helmet will be exposed to sunlight for a long time in summer, and Absorbing and accumulating heat from the sun will cause high temperature in the wearer's head area, which will affect the wearer's work, etc., and in severe cases will cause the wearer to suffer from heat stroke and other problems. However, the heat dissipation function of the existing helmet is single and cannot be controlled at will. In winter, due to the heat dissipation function, it will not be able to produce warmth.
