Embodiment 1

[0014] exist figure 1 In the first embodiment shown, the construction safety helmet includes a hemispherical hard shell 1 and an inner tank 2; the inner tank 2 is hemispherical inside the outer shell 1 and is lined on the inner surface of the outer shell 1, and The liner 2 goes around the periphery of the shell and rolls up to form a flange 21 that wraps the shell 1 tightly; the inside of the liner 2 is a hollow cavity, and the liner wall surrounding the hollow cavity is formed by elastic The thin wall 22 is formed, that is, the inner tank 2 is a cavity surrounded by a continuous elastic thin wall 22; the inner tank wall surface is evenly distributed with air holes.

[0015] In the above-mentioned construction safety helmet, the height from the lowermost end to the uppermost end of the flange 21 of the inner tank 2 is 4cm~6cm; a larger area of ​​the windward side is formed on the outside of the flange, and when there is external wind force, a larger amount of Outside air flow...

Abstract

The invention provides a construction safety helmet, which comprises a hemispherical hard case and an inner liner, wherein the inner liner is in a hemispherical shape inside the case, and is internally lined on the inner surface of the case; the inner liner bypasses the periphery of the case and is upwards flanged to form a flange tightly covering the case; a hollow cavity is formed inside the inner liner; the inner liner wall defining the hollow cavity is formed by an elastic thin wall, i.e., the inner liner is a cavity defined by the continuous elastic thin wall; and air holes are uniformly distributed in the surface of the inner liner wall. The construction safety helmet has the advantages that the ventilation performance is good; the dynamics comfortability is improved to a great degree; and the production and the assembly are easy.

Description

technical field [0001] The invention relates to the field of construction safety equipment, in particular to a construction safety helmet. Background technique [0002] In the field of engineering construction, due to safety issues, it is necessary to wear a safety helmet; the current safety helmet includes an outer shell and an inner tank; due to the need to ensure the mechanical strength of the outer shell, the surface of the outer shell cannot be made with ventilation holes, therefore, the current safety helmet has an air permeability Extremely bad, when workers work in hot weather, the air environment inside the helmet is hot and humid, which is extremely bad; More solid parts are formed on the bladder, and such strong parts cause bumps on the head, which greatly damages the mechanical comfort of the head. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a construction safety helmet, which not onl...
