Abstract
The utility model discloses a multi-layer safety air cushion. The multi-layer safety air cushion comprises at least three layers of air cushion bodies, wherein each layer of air cushion body is provided with an air charging port and an air exhaust port, a ventilation port is arranged between every two adjacent layers of air cushion bodies, the bottommost layer of air cushion body is connected with an expansion air bag, a valve port is arranged at the connecting position of the expansion air bag and the bottommost layer of air cushion body, the valve port is a one-way valve port, the passing direction of air is from the bottommost layer of air cushion body to the expansion air bag, and the valve port is opened when the air pressure at the valve port reaches preset air pressure. The multi-layer safety air cushion has the advantages that through the arranged expansion air bag, the pressure produced when an escaper jumps to the top of the multi-layer safety air cushion in the escape process can be transmitted to the lower layers of air cushion bodies from the topmost layer of air cushion body until the expansion air bag, the escaper can be buffered by impact of the air cushion, and the escaper can also be prevented from accidents and being flipped high.
Description
Technical field
The utility model 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.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of safety air cushion.
The utility model 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.
The beneficial effects of the utility model:
By expansion air bag is set, the pressure causing while skipping to multi-level safety air cushion top in the time of can making to escape starts to be transmitted toward lower floor's air cushion inflation by top layer air cushion, until expansion air bag, not only can make 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 utility model 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 utility model, 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 utility model, multi-level safety air cushion, by expansion air bag is set, the pressure causing while skipping to multi-level safety air cushion top in the time of can making to escape starts to be transmitted toward lower floor's air cushion inflation by top layer air cushion, until expansion air bag, not only can make 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 utility model and feature, and its object is to allow the personage who is familiar with this art can understand the utility model content and be implemented, and can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
