Electrical safety helmet structure and preparation method

Abstract

The invention discloses an electrical safety helmet structure and a preparation method. The structure comprises a safety helmet body, the body comprises a resin shell body, the resin shell body is filled with a foam aluminum central core body, and a plurality of safety hamlet connecting holes are formed in the edge of the helmet body of the resin shell body; a lining is arranged on the inner sideof the resin shell body, and lining connecting holes are formed in the edge of the lining; the lining and the foam aluminum central core body are fixedly connected in sequence through safety helmet connecting holes and the lining connecting holes by using a connection fastener. By adopting the design technology of the combination of the foam aluminum central core body and resin, the electrical safety helmet structure is light in weight, high in strength, and excellent in shock resistance and vibration reducing performance, which guarantees the life safety of field operating workers to a largerextent.

Description

technical field [0001] The invention relates to an electric safety helmet structure and a preparation method. 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. When the worker's head is impacted by falling objects, a qualified safety helmet can decompose the impact force to the entire area of ​​the skull in an instant through the cap shell and cap lining, and then use the elastic deformation and plasticity of the cushioning structure of each part to The deformation and allowable structural damage absorb most of the impact force, reducing the final impact force on the head of the personnel to below 4900N, thereby protecting the head of the operator. [0003] At present, the materials used in the manufacture of safety helmet shells in China mainly include ABS (combined with acrylonitrile, J-ene and propylen...

AI Technical Summary

Problems solved by technology

[0004] Compared with helmets made of other materials, FRP helmets generally have significant advantages such as high strength, good electrical properties, and good corrosion resistance, but they also have low elastic modulus, easy deformation, poor long-term temperature resistance, and low interlayer shear strength. and disadvantages of easy aging

Under the action of ultraviolet rays, wind, sand, rain and snow, chemical media, mechanical stress, etc., it is easy to cause performance degradation and even endanger the life safety of operators.
