the bottom of gas column is equipped with weak layer, weak layer is located in the lower chamber.
The elastic membrane is fixed with a plurality of sponge columns, and the sponge columns are positioned in the upper chamber and extend towards the top of the first pad body.
Compared with the prior art, the utility model discloses when the rescue, only need inflate at the less gas column of volume and the second pad body and just can rescue fast after up to standard, simultaneously, the person of falling is under the quadruple cushioning effect through the space between the second pad body, the second pad body and the first pad body, sponge post, elastic membrane, by safe, reliable catching, can not produce secondary damage, rational in infrastructure, the gas velocity is fast, and the protecting effect is good.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention;
in the figure: 1. a first pad body; 2. a blower; 3. a gas column; 4. a second pad body; 5. an air tube; 6. a branch pipe; 7. fastening the rope; 8. an elastic film; 9. an upper chamber; 10. a lower chamber; 11. a weak layer; 12. a sponge column.
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 air column type air cushion comprises a first cushion body 1 and a blower 2, wherein a plurality of air columns 3 are arranged in the first cushion body 1, the air columns 3 extend to the upper side of the first cushion body 1, a second cushion body 4 is also arranged above the first cushion body 1, and the plurality of air columns 3 are propped and communicated with the second cushion body 4; the joint of the air column 3 passing through the first cushion body 1 can be bonded by using materials with the same material to realize sealing, and a mechanism which can melt the first cushion body 1 and the air column 3 into a whole but is not communicated with each other can also be used in production; the total volume of the air column 3 and the second pad 4 is far smaller than that of the first pad 1;
the air columns 3 are communicated through air pipes 5, the air pipes 5 are also communicated with the air blower 2, branch pipes 6 are also arranged on the air pipes 5, and the branch pipes 6 are communicated with the first cushion body 1; the same sealing treatment is carried out on the part of the air pipe 5 passing through the first cushion body 1;
the upper part of the air column 3 is provided with a fastening rope 7. When rescue is needed, the whole air cushion is unfolded, the blower 2 acts, air is blown into the air column 3 and the first cushion body 1 through the air pipe 5 and the branch pipe 6, air enters the air column 3 and then enters the second cushion body 4, the fastening rope 7 is tightened after the air inflation amount of the second cushion body 4 reaches 70-80%, the communication between the air column 3 and the second cushion body 4 is cut off, the blower 2 continues to work, the air column 3 is small in size and reaches a saturated state relative to the first cushion body 1, at the moment, the first cushion body 1 is not saturated, the air column 3 is saturated, the second cushion body 4 is close to saturation, therefore, the saturated and tight air column 3 can reliably support the second cushion body 4, the second cushion body 4 is not saturated, the upper surface is not tight and elastic, a falling person can reliably buffer after contacting, no injury is caused, and a gap is reserved between the first cushion body 1 and the second cushion body 4 through the air column 3, the first cushion body 1 is used as a final buffer guarantee, the structure is reasonable, the phenomenon that a falling person impacts an air cushion to cause secondary injury is effectively avoided, the personal safety of the falling person is ensured, and compared with a traditional air cushion, the utility model discloses only need to be filled with the air column 3 with a smaller volume and the second cushion body 4, rescue can be implemented, the inflation process is fast, and the rescue efficiency is effectively improved; the side surface of the first cushion body 1 can be provided with a safety valve, so that the blower 2 works continuously, but the first cushion body 1 is not in a saturated state, and the falling person is ensured to contact with a soft air cushion with larger deformation.
An elastic membrane 8 is arranged in the first cushion body 1, the elastic membrane 8 divides the first cushion body 1 into an upper chamber 9 and a lower chamber 10 which are different from each other, the air column 3 penetrates through the elastic membrane 8, and the air pipe 5 and the branch pipe 6 are both positioned in the upper chamber 9;
the bottom of the gas column 3 is provided with a weak layer 11, and the weak layer 11 is positioned in the lower chamber 10. After the falling person impacts the second cushion body 4, the second cushion body 4 is pressed to move downwards, at the moment, the sealed air column 3 is extruded, the weak layer 11 is crushed, air in the air column 3 is extruded into the lower cavity 10, the lower cavity 10 is expanded, the elastic membrane 8 is upwards bulged, and therefore a flexible protective layer is formed again, the falling impact force of the falling person is completely absorbed, and the personal safety of the falling person is guaranteed; an openable sealing door may be provided at the bottom of the first pad body 1 for replacement of the weak layer 11.
A plurality of sponge columns 12 are fixed on the elastic membrane 8, and the sponge columns 12 are positioned in the upper chamber 9 and extend towards the top of the first pad body 1. Like this, under the expansion of cavity 10, elastic membrane 8 upwards swells, drives sponge post 12 rebound, when reliable energy absorption, has reduced the relative speed between sponge post 12 and the person that falls for the person that falls is caught under the effect of sponge post 12 safely, reliably.
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.
