Improved safety helmet for building construction

Abstract

The invention discloses an improved safety helmet for building construction. The improved safety helmet includes a bottom frame, an inner shell layer, a gas-filled layer and an outer shell layer. Theupper end of the bottom frame is provided with the inner shell layer, and the outer shell layer is disposed on the outer side of the inner shell layer. A buffer chamber is disposed between the inner shell layer and the outer shell layer. A solar power generation layer is arranged on the outer side of the outer shell layer. The outer shell layer at the front end of the safety helmet is provided with a telescopic rod, the tail end of the telescopic rod is provided with a lighting lamp, a hinge is disposed between the lighting lamp and the telescopic rod, the front end of the bottom frame on thelower side of the lighting lamp is provided with a cap brim, the lower end face of the cap brim is connected with protective lenses through hinged bases, the inner side of the inner shell layer is provided with the gas-filled layer, massage pads are evenly distributed on the inner side surface of the gas-filled layer, the gas-filled layer located at the tail of the safety helmet is provided with an inflating pipe, the inflating pipe penetrates the inner shell layer, the outer shell layer and the solar power generation layer and is connected with an air pump, and the inflating pipe located in abuffer layer is provided with a solenoid valve. The improved safety helmet is simple and reasonable in structure, adjustability of a safety helmet inner cavity is achieved, and the practicality of adevice is improved.

Description

technical field [0001] The invention relates to a safety device for building construction, in particular to an improved safety helmet for building construction. Background technique [0002] In construction sites, safety helmets are used as safety protective equipment that workers must wear when working, but at night or when the ambient light is not good, they cannot provide lighting, which is inconvenient to operate and cause difficulties for construction operations. The space inside the helmet is fixed, but the head shape of different people is uncertain, which leads to the problem that the helmet does not match the head shape of the worker, the wearing comfort is poor, and the wearing is not firm enough. Contents of the invention [0003] The object of the present invention is to provide an improved safety helmet for building construction, to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invent...
