Safety helmet used in building construction site

Abstract

The invention provides a safety helmet used in a building construction site and belongs to the field of buildings. The safety helmet comprises a helmet housing, a damping device, covering cloth and a protective top, wherein sponge is arranged on the periphery of the inside of the helmet housing, a damping zone is arranged at the top of the helmet housing, a sliding groove is formed in the inner wall of the periphery of the damping zone and is formed in the helmet housing, a protective block is arranged in the damping zone and is installed at the top of the helmet housing, convex blocks are arranged on the periphery of the protective block, the protective block is movably installed in the sliding groove through the convex blocks, a damping device is arranged at the bottom of the protective block, is arranged in the damping zone and consists of an upper fixing block, a lower fixing block and a damping spring. By arranging the damping device at the top of the helmet housing, the intensity of an object falling from the upper portion can be effectively buffered in the building construction site, the personal safety is protected to the most degree, and the security coefficient of the safety helmet in use at night is increased by arranging a fluorescent zone.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to a safety helmet for a construction site. Background technique [0002] 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.

Problems solved by technology

[0003] The safety helmets currently on the market have simple structures and poor protection capabilities. Especially in construction sites, because there are many safety hazards, it is easy to drop objects from high-rise buildings. Ordinary safety helmets cannot protect against this situation. Thereby can not satisfy the demand of actual situation, in order to solve the above-mentioned problem, the present invention provides a kind of safety helmet with construction site
