Coolant, described inner liner (14) lower surface coated with thermally conductive layer, described inner liner it is provided with in described inner liner (14)
(14) side and upper surface coating thermal insulation layer.
Being provided with foamed buffer layer (133) in described cushion (13), described foamed buffer layer (133) is in described high pressure zone
(132) top.
Some through holes penetrated for described spine (131) it are provided with in described foamed buffer layer (133).
Described high-pressure medium is gases at high pressure.
The thickness of described foamed buffer layer (133) is 5-15cm.
Described high pressure zone (132) sidepiece is provided with inflation inlet.
Described high pressure zone (132) sidepiece is provided with the pressure-detecting device of detection high-pressure medium pressure.
The utility model has the advantages that: 1) this utility model inner liner arranges coolant, dissipate to the head of fireman
Heat, improves the comfortableness of fireman, and this utility model arranges heat-conducting layer at the lower surface of inner liner, is specifically and fireman
The position of head contact arranges heat-conducting layer, is so more conducive to the heat radiation of fireman's head, simultaneously at the side of inner liner and upper table
Face arranges thermal insulation layer, reduces coolant speed of heat exchange from environment, thus can realize in a long time fireman's head
Heat radiation, further increases the comfortableness of fireman；
2) this utility model arranges flame-retardant layer, hard protection layer, cushion and inner liner, possess good fire resistance,
Possess good intensity, possess good anti-seismic performance, therefore can well protect the safety of fireman；This utility model buffers
Being provided with high pressure zone in Ceng, set high-pressure medium in high pressure zone, when so using, high-pressure medium can be under certain condition from high pressure zone
Inside discharge, greatly reduce the impact of external force, possessed good buffering effect；
3) this utility model further arranges foamed buffer layer in high pressure zone, and such foamed buffer layer can provide
One pipe protection, also avoids the release suddenly of high-pressure medium to cause opposite force excessive simultaneously, causes helmet body power upwards excessive,
Causing the injury to fire fighter, therefore the existence of foamed buffer layer protects the safety of fireman the most further；
4) some through holes penetrated for spine it are provided with in the further foamed buffer layer of this utility model, so can be with spine
After by certain force, pierce through high pressure zone by passage smoothly, thus discharge high-pressure medium and play good shock-absorbing capacity,
Further ensure the safety of fireman.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Figure 1 is helmet body, 2 for face shield；
11 be flame-retardant layer, 12 be hard protection layer, 13 be cushion, 14 for inner liner；
131 be spine, 132 be high pressure zone, 133 for foamed buffer layer.
Detailed description of the invention
This utility model includes helmet body 1 and is arranged on the face shield 2 of helmet body 1 front end, and described helmet body 1 is from outward
Flame-retardant layer 11, hard protection layer 12, cushion 13 and inner liner 14 the most successively；
Wherein cushion 13 is a hollow layer, and described cushion 13 upper surface has downwardly extended some spines 131, described slow
Rushing and be provided with high pressure zone 132 on layer 13 lower surface, described high pressure zone 132 seals and arranges, and is filled with high pressure in described high pressure zone 132
Medium；
Coolant, described inner liner 14 lower surface coated with thermally conductive layer, described inner liner 14 side it is provided with in described inner liner 14
And upper surface coating thermal insulation layer.
Being provided with foamed buffer layer 133 in described cushion 13, described foamed buffer layer 133 is in described high pressure zone 132
Top.
Some through holes penetrated for described spine 131 it are provided with in described foamed buffer layer 133.
Described high-pressure medium is gases at high pressure.
The thickness of described foamed buffer layer 133 is 5-15cm.
Described high pressure zone 132 sidepiece is provided with inflation inlet.
Described high pressure zone 132 sidepiece is provided with the pressure-detecting device of detection high-pressure medium pressure.
This utility model inner liner arranges coolant, dispels the heat to the head of fireman, improve the comfortableness of fireman,
This utility model arranges heat-conducting layer at the lower surface of inner liner, is specifically and the position of fireman's head contact arranges heat conduction
Layer, is so more conducive to the heat radiation of fireman's head, arranges thermal insulation layer in the side of inner liner and upper surface simultaneously, reduction coolant from
The speed of heat exchange in environment, thus the heat radiation to fireman's head can be realized in a long time, further increase fireman
Comfortableness
Work process of the present utility model is: when this utility model uses, when by external impacts, if impulsive force is not
Greatly, hard protective layer 12 just can play a very good protection；If when being subject to bigger impulsive force, 12, hard protection layer
Raw certain deformation, spine 131 moves downwardly to and contacts with high pressure zone 132 and punctured by high pressure zone 132 then, thus high pressure zone
High-pressure medium in 132 flows out in high pressure zone 132, thus plays cushioning effect.
When helmet body 1 of the present utility model is by impulsive force, first hard protection layer 12 plays ground floor protection, then
Foamed buffer layer 133 plays the protection of the second layer to fireman, then after impulsive force reaches to a certain degree, high pressure zone 132 quilt
Puncture, play the protection of the third layer to fireman.
This utility model foamed buffer layer 133, in addition to above-mentioned buffering plays second layer protective effect, also has following
Technique effect: if there is no foamed buffer layer 133, the high-pressure medium that the moment that high pressure zone 132 is punctured flows out can produce very
A big power upwards, such helmet body 1 can cause the damage to human body head to one upward force the biggest of human body head
Wound；This utility model foamed buffer layer 133 understands the protection certain to this bigger power offer, thus provides more to fireman
Comprehensively protection.
The further high-pressure medium of this utility model is gases at high pressure, utilizes the mobility of gas to make high pressure gas physical ability smooth
Each position flowing to helmet body 1, and then when can make helmet body 1 by impulsive force, all directions uniform force, it is to avoid
Local assault power is excessive and causes the injury to fireman, and this kind of mode can make helmet body 1 each portion uniform force, divides greatly
Dissipate impulsive force, further ensure that fireman's safety when impact.
The thickness of this utility model foamed buffer layer 133 can determine according to practical situation, high pressure zone 132 inner high voltage medium
Pressure can also determine according to practical situation, and this utility model can arrange pressure-detecting device on high pressure zone 132, the most permissible
Within further making the pressure of high pressure zone 132 inner high voltage medium be maintained at a zone of reasonableness according to practical situation, with maximum
The safety that ensure that fireman of limit, through actually detected, achieves good using effect.
