Embodiment Construction

[0026] Such as Figure 1-6 As shown, a fire emergency protection helmet includes an outer cover 1, a foldable impact-resistant mechanism, an X-shaped buffer belt, a safety airbag, a breathing apparatus 3 and an installation box. The outer cover 1 is made of soft aluminum foil fabric, and is provided with An eye window 2 and a neck cover; an X-shaped buffer belt is arranged between the outer cover 1 and the collapsible anti-shock mechanism;

[0027] The collapsible anti-shock mechanism includes a piece 6, a mouth-shaped special-shaped joint 7 and a triangular special-shaped joint 8. The pieces 6 are connected in twos by rivets to form a scissor structure. The mouth-shaped special-shaped joint 7 All four sides are provided with rotating shafts for connecting with the sheet 6; three sides of the triangular special-shaped joint 8 are provided with rotating shafts for connecting with the sheet 6;

[0028] The two scissor structures are connected in series and then connected with o...

Abstract

The invention relates to a fire emergency protection helmet. According to the technical scheme, the helmet comprises an outer cover, a folding shock resistance mechanism, an air bag restraint system, a breathing appliance and a mounting box, and the outer cover is made from a soft material; the folding shock resistance mechanism comprises a sheet piece, a mouth shaped special-shaped joint and a triangular special-shaped joint; the air bag restraint system comprises a head top air bag, an afterbrain air bag, a neck air bag and a connecting air pipe; the breathing appliance is connected to the outer cover, the folding shock resistance mechanism is placed in the outer cover, the head top air bag is connected to the mouth shaped special-shaped joint and the triangular special-shaped joint at the inner side of the middle of a hemispherical telescopic housing, the afterbrain air bag is placed in the outer cover, and the neck air bag penetrates through the outer cover and is placed outside the outer cover; the mounting box is internally provided with an air bottle and an air inflation switch. The fire emergency protection helmet is placed in the mounting box in a contraction state, can conduct air inflation immediately to be in a spreading state when fire occurs, and becomes a shock resistance protection helmet.

Description

technical field [0001] The invention relates to a protective helmet, in particular to a fire emergency protective helmet. Background technique [0002] With the rapid development of my country's social economy and the rapid advancement of industrialization and urbanization, urban fire accidents occur frequently, and casualties and losses are also increasing. In the process of fire escape, a perfect fire site protection device is very important for the protection of the life and property of the victims. However, the existing fire alarm system only has the function of sending out alarm signals, and cannot evaluate the fire information around the victims in real time, provide real-time escape guidance, plan relatively safe escape routes, and cannot effectively assist trapped persons to escape. At present, the civilian fire-fighting equipment used in China is mainly fire escape masks, which do not have impact resistance and cannot provide emergency protection for victims in eme...
