Abstract
The utility model relates to a safety helmet. The safety helmet comprises a helmet body. The helmet body comprises an outer shell layer, an aerogel layer and an inner protection layer. The aerogel layer is arranged between the outer shell layer and the inner protection layer. According to the utility model, the aerogel material is utilized, so that the safety helmet is smash-proof, bullet-proof, explosion-proof, fire-proof, heat-insulating and so on, can be widely applied to mining, field work, and building or industrial and mining enterprises, and can be used as a combat helmet; when the safety helmet encounters an instant external force under the situations of a falling rock, falling down, an explosive blast, a bullet, a fire hazard and the like, the safety helmet is capable of effectively protecting the head part of a person and reducing the damage to the head part to the maximum extent; and the most rigorous detection, a contact explosion test of 100g TNT, is carried out on the safety helmet, and the safety helmet is proved to have effective protection against the contact explosion of small equivalent ammunition.
Description
Technical field
The utility model relates to a kind of safety device, particularly, relates to a kind of crash helmet.
Background technology
At fire-fighting, mine construction, while instructing with a top integrate anti-and pound, the helmet of shellproof, fire prevention, the several functions such as explosion-proof can, to operator's sense of security, push up because of one the life that effective crash helmet can be saved operator when accident occurs.
As field construction or present the used helmet of ore worker, mostly adopt the resin compounded layer that is added with certain gusset to pound layer as anti-, polyurethane foam or polystyrene foam etc. are as cushion.This helmet has certain anti-function of pounding, but when running into house collapse, landslide, during the major disasters such as gas explosion, fire, these helmets do not possess safeguard function.
During soldier instructs, tend to run into such as bomb blast, the situations such as shooting, do the instruction helmet major function or anti-pound with shellproof on, explosion wave is not done to too many requirement, but often bomb blast damage damages much morely than bullet shooting afield, so make the instruction helmet, needs shellproof and explosion-proof having concurrently.
Therefore, if can develop, a kind ofly integrate anti-and pound, the crash helmet of shellproof, fire prevention, the several functions such as explosion-proof, will have huge market prospects and using value.
Utility model content
(1) utility model object
In order to solve the shortcoming of prior art, the purpose of this utility model is to provide a kind of crash helmet, and it has utilized aerogel material, can integrate anti-and pounds, shellproof, fire prevention, the several functions such as explosion-proof.
(2) technical scheme
The crash helmet that the utility model provides, comprises helmet body, and described helmet body comprises: outer shell, aerogel layer and sheath, described aerogel layer is arranged in the middle of outer shell and sheath.
The thickness of described aerogel layer is 15～30mm, preferably 20～25mm, more preferably 20mm.
The density of the aerogel material of described aerogel layer is 180～260kg/m
3, preferred 220kg/m
3.
The outer shell of described helmet body is shellproof, the anti-layer of pounding.The aerogel layer of described helmet body is explosion-proof, damping, thermal insulation layer.
The crash helmet that the utility model provides, also comprises: interior soft support, it is positioned at the first half of described helmet body sheath.Can be stuck in operator's head.
The crash helmet that the utility model provides, also comprises: protect order baffle plate, it is positioned at the position of windowing of described helmet body.It can be transparent protecting order baffle plate, by protecting order baffle plate operator, can observe external environment condition.
(3) beneficial effect
The utility model provides a kind of crash helmet, and this helmet has utilized aerogel material, has anti-pounding, and shellproof, explosion-proof, fire prevention, the advantage such as heat insulation, can be widely used in mine, field work, building or industrial and mining enterprises, work instruction steel helmet etc.; When running into moment external force as falling rocks, drop, explosion wave, bullet, the situations such as fire can be protected head effectively, reduce to greatest extent the injury to head; By the detection the most harsh to the helmet: 100g TNT contact explositions experiment confirm crash helmet to little equivalent ammunition contact explositions can effectively protect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of crash helmet structure; In figure, 1, interior soft support, 2, the outer shell of helmet body, 3, protect order baffle plate, 4, the aerogel layer of helmet body, 5, the sheath of helmet body.
The specific embodiment
Following examples are used for illustrating the utility model, but are not used for limiting protecting scope.
