Description

Anti-riot helmet with anti-killing shrapnel capacity

Technical Field

The utility model belongs to the technical field of the personal protection, concretely relates to have anti-riot helmet of killing and killing shrapnel ability suitable for it is alert with or civilian.

Background

The terrorist attacks in the world are global risks, have sudden and bad properties and have serious influence on the life and property safety of people. The wide armed police and police officers will face a more severe form as law enforcement and management personnel. For these situations, not only are these strong departments required to have higher combat quality, but also equipment quality and performance are required to improve safety and survivability. The importance of anti-riot helmets as a means of protection for the head is not self-evident.

At present, the anti-riot helmet generally adopts a glass fiber helmet, a steel helmet, an aramid helmet and the like, but the helmet only has the functions and effects of basic knife prevention, smashing prevention, simple hand-made guns and the like, but is used for facing and maintaining various complex terrorist forms in various regions of the country, obviously, the basic anti-riot helmet cannot meet the use requirement at present, and becomes an important research and development direction for further improving the anti-impact and bulletproof capabilities.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide an anti-riot helmet with anti-killing shrapnel ability, it has high shock resistance, high anti-strike ability and high flame retardant property.

In order to realize the purpose, the technical scheme of the utility model is that:

the anti-riot helmet with the anti-killing shrapnel capacity comprises a helmet shell, a buffer layer, a liner, a face mask and a neck guard, wherein the helmet shell is movably connected with the face mask, the helmet shell is of a multi-layer anti-killing shrapnel structure and comprises a shell, an epoxy resin layer and a flame-retardant layer, and high-molecular-weight polyethylene fiber cloth is cured in the epoxy resin layer.

As a further improvement of the utility model: the cushioning layer includes a top cushioning layer and a peripheral cushioning layer that are snap-fit to one another, which facilitates replacement and manufacture.

As a further improvement of the utility model: the peripheral cushioning layer is wrapped with a pad, and a cavity is formed between the top of the pad and the top cushioning layer. Because the liner wraps the peripheral buffer layer, and the peripheral buffer layer is clear and fixed in position relation, the deformation of the liner is greatly reduced, and the position of a cavity between the liner and the buffer layer is ensured, so that the shock resistance and the anti-striking capability of the helmet are greatly improved.

As a further improvement of the utility model: the flame-retardant layer is made of diamino diphenyl sulfone material, so that the flame-retardant performance of the helmet is further improved.

As a further improvement of the utility model: the high molecular weight polyethylene fiber cloth adopts 1500-3000D high molecular weight polyethylene fiber, so that the impact resistance and the cutting resistance of the polyethylene fiber cloth are further improved.

As a further improvement of the utility model: the top buffer layer and the peripheral buffer layer are made of polystyrene resin materials, so that the shock-proof and flame-retardant multilayer heat-insulation cushion has the shock-proof and flame-retardant effects while preserving heat and insulating heat.

The utility model discloses an epoxy makes shell, fire-retardant layer and high molecular weight polyethylene fiber cloth fuse in an organic whole, utilizes high molecular weight polyethylene fiber to have impact resistance, and specific energy absorbs characteristics such as big, gentle, makes the anti-riot helmet basically at original performance, and the performance further promotes greatly, has possessed through detecting that it prevents killing and killing shrapnel ability, has had thermal-insulated, characteristics such as fire-retardant simultaneously.
