Abstract
The invention discloses a multilayer safety air cushion which at least comprises three layers of air cushions, wherein an inflation port and an exhaust port are arranged on each of the air cushions; a ventilation port is arranged between every two adjacent air cushions; the lowest air cushion is connected with an expansion air bag; a valve port which is a check valve port is arranged between the expansion air bag and the lowest air cushion; air is inflated in the direction from the lowest air cushion to the expansion air bag; the valve port is opened when the air pressure at the valve port reaches the preset air pressure. The multilayer safety air cushion has the advantages that by arranging the expansion air bag, the pressure generated by the situation that people jump onto the top of the multilayer safety air cushion when escaping is transferred until to the expansion air bag in the mode that air is inflated from the highest air cushion to the lowest air cushion. Therefore, people are cushioned by means of impact of the air cushion and are not likely to fly out of the safety air cushion accidently.
Description
Technical field
The present invention relates to a kind of safety air cushion, especially multi-level safety air cushion.
Background technology
Safety air cushion, claims again life saving gas cushion, is a kind of lifesaving appliance of high altitude escape.The features such as it is short that it has inflationtime, and buffering effect is remarkable, easy to operate, safe and reliable.Conventionally adopt the high fiber strength strains with fire resistance to make, there is fire-retardant, wear-resisting, ageing-resistant, folding convenient, the features such as long service life.At present, the safety air cushion that tradition is used exists survivor is impacted to excessive defect,, if survivor's hop is too high, when skipping to safety air cushion, easily by safety air cushion bullet, is flown meanwhile, has certain hidden danger.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of safety air cushion.
The present invention is achieved through the following technical solutions.
A kind of multi-level safety air cushion, comprise at least three layers of air cushion, above-mentioned every layer of air cushion is provided with inflation inlet and exhaust outlet, above-mentioned adjacent cushions is provided with blow vent, the air cushion of above-mentioned lowermost layer is connected with expansion air bag, and the air cushion junction of above-mentioned expansion air bag and above-mentioned lowermost layer is provided with valve port, and above-mentioned valve port is check-valve port, the direction that gas passes through be the air cushion of the bottom to expanding air bag, when the air pressure at above-mentioned valve port place reaches default air pressure, opens.
Further, above-mentioned valve port place is provided with pressure sensor.
Further, above-mentioned air cushion is provided with four layers.
Beneficial effect of the present invention:
By expansion air bag is set, can so that when escape the pressure that causes while skipping to multi-level safety air cushion top by top layer air cushion, start toward lower floor's air cushion inflation to be transmitted, until expansion air bag, not only can be so that survivor receive that the impact of air cushion is cushioned, can also prevent from that survivor is difficult for meeting accident to be flown by safety air cushion bullet.
Accompanying drawing explanation
Fig. 1 is the structural representation of the implementation case multi-level safety air cushion.
The specific embodiment
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural representation of the implementation case multi-level safety air cushion, with reference to Fig. 1, the present invention, multi-level safety air cushion, comprise at least three layers of air cushion 1, every layer of air cushion 1 is provided with inflation inlet 2 and exhaust outlet 3, adjacent cushions 1 is provided with blow vent (not shown), the air cushion 1 of lowermost layer is connected with and expands air bag 4, expand air bag 4 and be provided with valve port 5 with air cushion 1 junction of lowermost layer, valve port 5 is check-valve port, and the air cushion 1 that the direction that gas passes through is the bottom, to expanding air bag 4, is opened when the air pressure at valve port 5 places reaches default air pressure.
In the implementation case, valve port 5 places are provided with pressure sensor 50.
In the implementation case, air cushion 1 is provided with four layers.
The present invention, multi-level safety air cushion, by expansion air bag is set, can so that when escape the pressure that causes while skipping to multi-level safety air cushion top by top layer air cushion, start toward lower floor's air cushion inflation to be transmitted, until expansion air bag, not only can be so that survivor receive that the impact of air cushion is cushioned, can also prevent from that survivor is difficult for meeting accident to be flown by safety air cushion bullet.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow the personage who is familiar with this art can understand content of the present invention and be implemented, and can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
