Abstract
The utility model discloses a novel life jacket capable of quickly and automatically aerating. The novel life jacket comprises a life jacket main body, wherein a gas production device is arranged in the life jacket main body, the gas production device comprises a trigging portion, a reaction portion placed on the top portion and a gas production portion arranged on the lower end of the reaction portion, wherein the triggering portion is a blasting needle or a support beam, the reaction portion is a water bag, a calcium carbide is placed in the gas production portion, and the lateral surface of the gas production portion is provided with an air outlet which is communicated with the left jacket main body. The novel life jacket capable of quickly and automatically aerating is not only safe, but also quickly aerates, and has low cost, practicability, easy carrying and easy operation.
Description
Technical field
The utility model relates to a kind of life jacket, relates in particular to a kind of fast automatic gas filed life jacket.
Background technology
In the life, because the people that are everlasting under-water operation and are engaged in aquatic products for a long time are through regular meeting's situation that faces a danger.Skilled water-based knots as trick, even can be drowned too.It is more to be used for the buoyant apparatus that the drowned accident of water saves oneself in the prior art, for example existing life jacket gas of having substituted the bad for the good, but under emergency situation, be inconvenient to carry.Also have a kind of chemical reaction that adopts, the swimmer carries in water, and initiator reactor when running into situation makes it produce gas, reaches the purpose of saving oneself.The weak point of this buoyant apparatus is that to produce gas slow, dangerous.
The utility model content
The purpose of this utility model be to provide a kind of not only safety but also fast, cost is low, practical, portable, the novel fast automatic inflatable lifejacket of easy-to-operate.
To achieve these goals, the technical solution of the utility model is: a kind of novel fast automatic inflatable lifejacket is provided, comprises the life jacket body, wherein, be provided with aerogenesis apparatus in the described life jacket body; Described aerogenesis apparatus comprises initiation portion, place the reacting part at top, place the aerogenesis portion of reacting part lower end; Described initiation portion is explosion pin or support membrane, and reacting part is a water bag, is placed with calcium carbide in the aerogenesis portion, and aerogenesis portion side offers the air extractor duct that communicates with the life jacket body.
The beneficial effects of the utility model are: the fast automatic inflatable lifejacket of the utility model not only safety but also fast aeration, cost is low, practical, portable, easy to operate.
Description of drawings
Fig. 1 is the fast automatic inflatable lifejacket structural representation of the utility model;
Fig. 2 is the first example structure scheme drawing of aerogenesis apparatus 2 among Fig. 1;
Fig. 3 is the second example structure scheme drawing of aerogenesis apparatus 2 among Fig. 1.
The fast automatic inflatable lifejacket of the utility model is by 1 expression life jacket body as can be known as Fig. 1,2,3, and 2 represent aerogenesis apparatus, 21 expression explosion pins, 22 expression water bags, 23 expression aerogenesis portions, 24 expression calcium carbides, 25 expression shells, 3 express gas port, 4 expression filtering nets, 5 expression support membranes.
The specific embodiment
For the technology contents, the structural attitude that describe the fast automatic inflatable lifejacket of the utility model in detail, be described further below in conjunction with embodiment and conjunction with figs..
Embodiment one
As shown in Figure 1, 2, the fast automatic inflatable lifejacket of the utility model, comprise life jacket body 1, wherein, be provided with aerogenesis apparatus 2 in the described life jacket body 1, described aerogenesis apparatus 2 comprises shell 25, place shell 25 inner tops reacting part, place the aerogenesis portion 23 of reacting part lower end and place the initiation portion of reacting part side.Described shell 25 is the elasticity of plastics capsule, and initiation portion is an explosion pin 21, and described reacting part is a water bag 22, is placed with calcium carbide 24 in the aerogenesis portion 23, and aerogenesis portion 23 sides offer the air extractor duct 3 that communicates with life jacket body 1.Be provided with filtering net 4 between air extractor duct 3 and the aerogenesis portion 23,4 of filtering nets allow gas to pass through, and calcium carbide 24 impassabitity air extractor ducts 4 enter in the life jacket body 1.
When facing a danger, by push the explosion pin 21 in the shell 25 from the outside of life jacket body 1, explosion pin 21 squeezes one's water breaks bag 22, this moment, water bag 22 interior water flow in the aerogenesis portion 23, this moment, chemical reaction took place with water in calcium carbide 24 fast, utilize CaC2+2H2O==Ca in the chemistry (OH) 2+C2H2 ↑ principle to react rapidly and produce C2H2 gas, because calcium carbide 24 is violent with the water reaction, it is fast rapidly to produce gas, gas is full of in the whole life jacket body 1 fast by air extractor duct 4, reaches to rescue people's purpose fast.
Embodiment two
Shown in Fig. 1,3, the fast automatic inflatable lifejacket of the utility model, comprise life jacket body 1, wherein, be provided with aerogenesis apparatus 2 in the described life jacket body 1, described aerogenesis apparatus 2 comprise shell 25, place the reacting part of shell 25 inner tops, place the aerogenesis portion 23 of reacting part lower end and place reacting part and aerogenesis portion 23 between initiation portion; Described shell 25 is the elasticity of plastics capsule, and reacting part is a water bag 22, and initiation portion is a support membrane 5, is placed with calcium carbide 24 in the aerogenesis portion 23, and aerogenesis portion 23 sides offer the air extractor duct 3 that communicates with life jacket body 1.Be provided with filtering net 4 between air extractor duct 3 and the aerogenesis portion 23,4 of filtering nets allow gas to pass through, and calcium carbide 24 impassabitity air extractor ducts 4 enter in the life jacket body 1.
When facing a danger, by outside life jacket body 1, firmly pushing shell 25, this moment, shell 25 interior support membranes 5 broke, this moment, water bag 22 interior water flow in the aerogenesis portion 23, and this moment, calcium carbide 24 with water chemical reaction took place fast, utilized the rapid reaction of CaC2+2H2O==Ca in the chemistry (OH) 2+C2H2 ↑ principle to produce C2H2 gas, because calcium carbide 24 is violent with the water reaction, it is fast rapidly to produce gas, and gas is full of in the whole life jacket body 1 fast by air extractor duct 4, reaches to rescue people's purpose fast.
The fast automatic inflatable lifejacket of the utility model not only safety but also fast aeration, cost is low, practical, portable, easy to operate.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
