[0013] The first embodiment is stated as:

[0014] A double-layer construction safety helmet equipped with a spring buffer is characterized in that:

[0015] Mainly include:

[0016] The hood inner cap, the steel outer cap, and a number of buffer springs connecting the hood inner cap and the steel outer cap, wherein: the hood inner cap is made of high mechanical strength resin material, with lining cloth inside, and the thickness of the lining cloth is About 15MM;

[0017] The steel outer cap is made of aluminum alloy with a thickness of about 3 mm;

[0018] 20 to 30 small round holes are evenly distributed on the outer edge of the ring-shaped inner cap of the hood,

[0019] There are 20 to 30 small round holes evenly distributed on the outer edge of the steel outer cap, and the total number of all the aforementioned round holes is exactly the same, and their positions correspond to each other;

[0020] Between each pair of corresponding two round holes, there is also a hi...

Abstract

The invention aims at providing a double-layer structure construction safety helmet equipped with a spring buffer, and relates to the field of construction auxiliary equipment, in particular to a safety helmet. A shell of an existing safety helmet is generally not thick, the common thickness is about 3 MM, and the buffering property is poor. In order to achieve the purpose, the safety helmet mainly comprises a head covering inner cap, a steel outer cap and multiple buffer springs connecting the head covering inner cap with the steel outer cap; the head covering inner cap is made from high mechanical strength resin materials and internally provided with lining cloth, and the thickness of the lining cloth is about 15 MM; the steel outer cap is made from aluminum alloy materials, and the thickness is about 3 MM; twenty to thirty small circular holes are uniformly distributed in an annular circle of the outer edge of the head covering inner cap, and twenty to thirty small circular holes are uniformly distributed in an annular circle of the outer edge of the steel outer cap, and the total numbers of all the circular holes are completely the same. In this way, the double-layer structure construction safety helmet has the advantage of being higher in buffering effect.

Description

technical field [0001] The invention relates to the field of building auxiliary equipment, in particular to a safety helmet. Background technique [0002] The shell of the existing safety helmet is generally not thick, and the common thickness is about 3MM, and its cushioning performance is not good. Contents of the invention [0003] This invention aims to provide a kind of double-layer construction safety helmet that is equipped with spring cushioning, for this purpose, the technical scheme of this invention is set forth as follows: [0004] A double-layer construction safety helmet equipped with a spring buffer is characterized in that: [0005] Mainly include: [0006] The hood inner cap, the steel outer cap, and a number of buffer springs connecting the hood inner cap and the steel outer cap, wherein: the hood inner cap is made of high mechanical strength resin material, with lining cloth inside, and the thickness of the lining cloth is About 15MM; [0007] The st...
