Abstract
The utility model relates to a head protective device, in particular to a safety helmet. The safety helmet comprises a helmet shell, a lining arranged in the helmet shell, and a wearing elastic band arranged on the helmet shell, wherein the helmet shell is formed by clamping one or a plurality of ballistic nylon cloth layers among a plurality of fiber layers, and then wrapping a resin layer at the outermost layer. Preferably, one or two ballistic nylon cloth layers are arranged. The fiber layers can be glass fiber layers, plant fiber layers, carbon fiber layers or aromatic polyamide composite fiber layers. The safety helmet has both toughness and hardness, and greatly improves the safety coefficient of a helmet wearer.
Description
Technical field
The utility model relates to head restraint, relates in particular to a kind of crash helmet.
Background technology
Crash helmet is the harness of protection head, is not only soldier training, as the cap of wearing wartime, also is instrument indispensable in people's traffic.Its many semicircular in shape mainly is made up of shell, lining and suspension arrangement three parts.Shell is made of materials such as special steel, fiberglass, reinforced plastics, leather, nylon respectively, to resist the injury to head of bullet, shell fragment and other strike things.
Therefore, the safety to the wearer of the rerum natura of crash helmet (being strength and toughness) also is vital.Have only the reliable crash helmet of safe wearing, could when meeting accident, really play the effect of security protection.Existing crash helmet all be to adopt fibrage moulding such as string, glass fibre, carbon fibre, wrapped resin and forming again.In order to improve the hardness of crash helmet, generally can add one deck hard metal layer, such as steel mesh etc. in the fibrage intermediate layer.Do not have toughness but this crash helmet has hardness, and quality is big, and after resin-bonded, toughness reduces, and is frangible.
The utility model content
Therefore, at above-mentioned deficiency, the utility model proposes a kind of crash helmet that can have hardness and toughness concurrently.
The technical solution of the utility model is:
A kind of crash helmet comprises helmet shell, is arranged at the liner in the helmet shell and is arranged at the elastic cord of wearing on the helmet shell.Wherein, described helmet shell is by sandwiching one or more layers trajectory nylon layer of cloth between the multi-layer fiber layer, the resin-coated again layer formation of outermost layer.
Further, described trajectory nylon layer of cloth is one deck or two layers.
Further, described fibrage is that glass layer or plant fiber layer or carbon fiber layer or Kev draw (aramid fiber is compound) fibrage.
The utility model adopts as above technical scheme, by between the multi-layer fiber layer, sandwiching one or more layers trajectory nylon layer of cloth, than the helmet structure that adds the hard metal layer, toughness improves greatly, and quality declines to a great extent, than adding conventional nylon cloth, polyethylene cloth (POLYESTER) or cotton (COTTON), all exceed more than the several times in wear-resisting, toughness.Therefore, crash helmet of the present utility model has toughness and hardness concurrently, has improved the safety coefficient of helmet wearer greatly.
Description of drawings
Fig. 1 is a crash helmet profile schematic diagram of the present utility model;
Fig. 2 is the deck structure schematic diagram of crash helmet of the present utility model.
The specific embodiment
Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult illustrated in figures 1 and 2ly, crash helmet of the present utility model comprises helmet shell 1, is arranged at the liner in the helmet shell 1 and is arranged at the elastic cord of wearing on the helmet shell 1.Wherein, described helmet shell 1 is by sandwiching one or more layers trajectory nylon layer of cloth 103 between the multi-layer fiber layer 102, resin-coated again layer 101 formation of outermost layer.
Preferably, described trajectory nylon layer of cloth 103 is one deck or two layers.Described fibrage 102 is that glass layer or plant fiber layer or carbon fiber layer or Kev draw the aramid fiber composite fibre layer.
The utility model sandwiches one or more layers trajectory nylon cloth between the multi-layer fiber layer, have hardness and pliability concurrently, the trajectory nylon cloth has cloth and organizes characteristic firm, wear-resistant, tear-proof, and therefore crash helmet of the present utility model has the advantage of toughness and rigidity concurrently.
The production technology of crash helmet of the present utility model is: mould is heated to 100 ℃ → mould inner wall and was cleaned → go up gel coat (POLYESTER) → matched moulds → put fiber+trajectory nylon cloth+resin → put into airbag → insulation 10 minutes.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
Claims (3)
