FIG. 2 is a schematic structural view of the guard mechanism;

in the figure: 1. a helmet body; 2. a binding belt; 3. a neck guard curtain; 4. a sheath; 5. an air bag; 6. a damper plate; 7. a gap; 8. an air pipe; 9. sealing the end; 10. extruding the block; 11. perforating; 12. a spring.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the emergency fire-fighting helmet comprises a helmet body 1, a binding belt 2 and a neck curtain 3, wherein the binding belt 2 is arranged to ensure that the helmet body 1 can be firmly fixed on the top of the helmet body 1, the top of the helmet body 1 is provided with a protection mechanism, the protection mechanism comprises a sheath 4 arranged on the top of the helmet body 1, the bottom of the sheath 4 is provided with an airbag 5, the top of the sheath 4 is provided with an elastic damping plate 6, and a gap 7 is formed between the damping plate 6 and the airbag 5;

compressed gas is equipped with in the gasbag 5, rib curtain 3 is hollow bag column structure, gasbag 5 with communicate through trachea 8 between the rib curtain 3, trachea 8's one end and 5 intercommunications of gasbag and be equipped with the head 9 that the fragility is high. Damping plate 6 is located helmet body 1's top, play preliminary guard action, it is great when falling object impact, damping plate 6 produces great deformation back, damping plate 6 can support and press gasbag 5, make compressed gas in the gasbag 5 further compressed, and then make gas impact and break head 9, highly compressed gas passes through trachea 8 and enters into in the neck curtain, make the neck curtain inflation, because the one end and the helmet body 1 of neck curtain are connected, the other end is put on user's shoulder, therefore, inflate the back at the neck curtain, the neck curtain can play the supporting role to helmet body 1, and will fall the object and transmit to user's shoulder impact to helmet body 1's shoulder, the pressure to the neck has just also been reduced, therefore, the steam generator is reasonable in structure, the protective capacities has further been improved.

The other end of the air pipe 8 is attached to the helmet body 1 and communicated with the neck protecting curtain 3.

One end of the air pipe 8 penetrates through the sheath 4 and extends into the air bag 5, and the joint of the air pipe 8 and the sheath 4 is sealed through a sealant. Like this, can reliably seal between the one end of trachea 8 and the sheath 4, and through the sealed mode of gluing of getting rid of, can extract trachea 8 from gasbag 5 and sheath 4 in, and then realize the change of head 9.

The top of the damping plate 6 is flush with the top of the sheath 4, a plurality of squeezing blocks 10 are arranged at the bottom of the damping plate 6, and the squeezing blocks 10 are arranged at intervals and point to the air bag 5. Through the setting of extrusion piece 10, be convenient for improve the striking effect to gasbag 5, ensure that gasbag 5 that has expanded can break through head 9 under the extrusion of extrusion piece 10, realize the inflation of neck curtain.

The helmet is characterized in that a plurality of vertical through holes 11 are formed in the air bag 5, the through holes 11 are not communicated with the air bag 5, springs 12 are arranged in the through holes 11, one ends of the springs 12 are fixedly connected with the helmet body 1, and the other ends of the springs 12 are fixedly connected with the top of the damping plate 6. Through the setting of spring 12, play further cushioning effect, improve the threshold value that shock attenuation board 6 or extrusion piece 10 striking gasbag 5, when guaranteeing that the protecting effect is good, avoid gasbag 5 to strike head 9 prematurely, reduce and use maintenance cost.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
