Abstract
The invention discloses multilayer safety air cushions, including at least three layers of air cushion, above-mentioned every layer of air cushion is both provided with inflating port and exhaust outlet, above-mentioned adjacent cushions are 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, gas by direction for the bottom air cushion to air bag is expanded, the air pressure at above-mentioned valve port is opened when reaching preset pressure.The beneficial effects of the present invention are, expand air bag by setting, pressure starts to be transferred toward lower floor's air cushion inflation by top air cushion caused by when can to skip to during escape at the top of multilayer safety air cushion, until expand air bag, it can not only so that the impact that survivor receives air cushion is buffered, be also prevented from survivor and be not susceptible to surprisingly by safety air cushion bullet be flown.
Description
Technical field
The present invention relates to safety air cushions, especially multilayer safety air cushion.
Background technology
Safety air cushion, also known as life saving gas cushion are the lifesaving appliances of high altitude escape.It is short with inflationtime, buffering effect
Significantly, it is easy to operate, it is safe and reliable the features such as.The high fiber strength strains that generally use has flame retardant property are made, and have
The features such as fire-retardant, wear-resisting, ageing-resistant, folding convenient, service life is long.At present, the safety air cushion that tradition uses exists to escape
Person causes to impact the defects of excessive, meanwhile, if the jump point of survivor is excessively high, when skipping to safety air cushion easily by safety
Air cushion bullet flies, and has certain hidden danger.
The content of the invention
The technical problem to be solved in the present invention is to provide safety air cushions.
The present invention is achieved through the following technical solutions.
Multilayer safety air cushion, including at least three layers of air cushion, above-mentioned every layer of air cushion is both provided with inflating port and exhaust outlet, above-mentioned
Adjacent cushions are provided with blow vent, and the air cushion of above-mentioned lowermost layer is connected with expansion air bag, above-mentioned expansion air bag and above-mentioned lowermost layer
Air cushion junction be provided with valve port, above-mentioned valve port is check-valve port, gas by direction for the bottom air cushion to expanding
Air bag, the air pressure at above-mentioned valve port are opened when reaching preset pressure.
Further, it is provided with pressure sensor at above-mentioned valve port.
Further, above-mentioned air cushion is provided with four layers.
Beneficial effects of the present invention：
Expand air bag by setting, pressure caused by when can to skip to during escape at the top of multilayer safety air cushion passes through most
Top layer air cushion starts to be transferred toward lower floor's air cushion inflation, until expanding air bag, can not only survivor be caused to receive air cushion
Impact is buffered, and is also prevented from survivor and is not susceptible to surprisingly by safety air cushion bullet be flown.
Description of the drawings
Fig. 1 is the structure diagram of the implementation case multilayer safety air cushion.
Specific embodiment
The present invention is described in further detail below according to drawings and examples.
Fig. 1 is the structure diagram of the implementation case multilayer safety air cushion, of the invention with reference to Fig. 1, multilayer safety air cushion,
Including at least three layers of air cushion 1, every layer of air cushion 1 is both provided with inflating port 2 and exhaust outlet 3, and adjacent cushions 1 are provided with blow vent (figure
In do not show), the air cushion 1 of lowermost layer, which is connected with, expands air bag 4, expands air bag 4 and 1 junction of air cushion of lowermost layer is provided with valve
Mouthfuls 5, valve port 5 is check-valve port, gas by direction for the bottom air cushion 1 to air bag 4 is expanded, the air pressure at valve port 5 reaches
It is opened during to preset pressure.
In the implementation case, pressure sensor 50 is provided at valve port 5.
In the implementation case, air cushion 1 is provided with four layers.
The present invention, multilayer safety air cushion expand air bag by setting, and can to skip to multilayer safety air cushion top during escape
Pressure caused by during portion starts to be transferred toward lower floor air cushion inflation by top air cushion, not only can be with until expand air bag
So that the impact that survivor receives air cushion is buffered, it is also prevented from survivor and is not susceptible to surprisingly by safety air cushion bullet be flown.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with this field technology
Personage can understand present invention and be carried out, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made should all cover within the scope of the present invention.
