Description

Air bag structure

Technical Field

The utility model relates to a life saving equipment field especially involves an air bag structure.

Background

With the increasing of the automobile keeping quantity year by year, automobile accidents occur frequently, particularly accidents that the automobile falls into water frequently, because the space of the automobile is narrow, no special space is arranged in the automobile to equip equipment for saving life when falling into water, and once falling into water occurs, if people in the automobile take improper life-saving measures, the death rate is very high. However, when the automobile falls into water, the door is closed tightly, and water does not flow into the automobile at once, so that the escape time from falling into water to sinking into the water bottom is a few minutes.

The product of a name drowned bracelet of saving oneself has appeared on the market at present, and its effect principle is to pass through a access connection with high-pressure carbon dioxide gas cylinder and gasbag body, and this passageway is inside to have a firing pin to aim at the sealed department of gas cylinder mouth, and the outside has the one end of a spanner to promote the firing pin to remove to the gas cylinder mouth, and the firing pin punctures the gas cylinder sealed mouth when pulling the outside one end of this spanner, and the gasbag body just can be inflated by the inside high-pressure gas of gas cylinder rapidly, and then provides extra buoyancy for the person of wearing.

The product adopts the high-pressure gas cylinder as the source of inflation gas, and the further light weight of the bracelet is limited by the factors of the volume and the weight of the high-pressure gas cylinder, so that the existing bracelet is large in volume, heavy in weight and inconvenient to use; meanwhile, when the high-pressure gas cylinder is worn, the gas cylinder is likely to explode under the conditions that the shell of the high-pressure gas cylinder is violently impacted, or the high-temperature insolation in summer, or the salt of seawater corrodes the gas cylinder, and the like, so that potential safety hazards are brought to users.

Disclosure of Invention

The main object of the present invention is to provide an air bag structure that is easy to carry about, safe to use and fast to inflate.

In order to achieve the above purpose, the utility model adopts the technical scheme that: an airbag structure comprising an airbag body which is folded in a normal state and inflated and deployed in an emergency, said airbag body having an airbag nozzle fixed thereto, said airbag nozzle being opened or closed by an airbag cover, characterized in that: the air bag nozzle is provided with a vent hole, the diameter of the vent hole is not shorter than 10mm and not longer than 30mm, and the air bag body is connected with a tether.

The gasbag mouth include air cock seat, depression bar, spring and sealing washer, the air vent set up the air cock seat in, the air vent in be fixed with a mount pad, the one end of depression bar pass the mount pad after with the sealing washer fixed, the sealing washer be located the bottom of air cock seat, the spring setting be in the mount pad with the depression bar between, and be used for making the depression bar keep the trend of upward movement, the gasbag lid pass through the connecting piece and connect the air cock seat on. In this structure, the sealing washer is located the bottom of air nozzle seat, and it is used for sealing the air vent, and under the condition that does not have external force, the depression bar keeps the trend of upward movement under the effect of spring to can drive the sealing washer and block up the air vent, prevent that this internal gas of gasbag from leaking outward.

The mounting seat is connected with the inner wall of the vent hole through a plurality of circumferentially and uniformly distributed connecting ribs, and a ventilation area is formed between the adjacent reinforcing ribs. In this structure, when blowing toward this internal, gaseous through from the regional flow direction sealing washer of ventilating, the sealing washer receives the influence of gas down, and form the passageway of ventilating between with the air cock seat to do benefit to gaseous entering into gasbag body.

The mount pad have one supply the perforation that the depression bar passed, the fenestrate lateral wall on the circumference equipartition have a plurality of guide ways, the lateral wall of depression bar on the circumference equipartition have with guide way complex direction muscle, the direction muscle slide locate the guide way. In this structure, the guide rib cooperates with the guide way, plays the effect of direction to the motion of depression bar.

The airbag is characterized in that through grooves are formed in two sides of the airbag body respectively, and the head end of the tether sequentially penetrates through the two through grooves and then is connected with the tail end of the tether. In the structure, the tether is arranged on the air bag body in a surrounding mode, so that after the air bag body is expanded, a hand can be conveniently stretched into the space between the tether and the air bag body from any side.

One side of the air bag body is provided with an extending part in an extending way, and the air bag nozzle is fixed on the extending part. Thereby facilitating blowing.

The material of the air bag body is TPU. In the structure, the TPU material is the prior art, and the TPU material has better air tightness, water resistance and wear resistance.

The color of the outer surface of the air bag body is yellow. The yellow color is more attractive than other colors, so that the yellow color is easy to be found by people.

The tether is made of nylon woven tape. In the structure, the nylon woven tape has better wear resistance.

The diameter range of air vent be 15mm ~ 20mm, less air vent is unfavorable for quick inflation, great air vent then is unfavorable for aerifing with the mouth, through many times experimental contrast, the diameter range of air vent is 15mm ~ 20mm, at the inflated in-process, most gas can enter into the gasbag smoothly originally internally, reach the purpose that the short time can quick inflation, still do benefit to the quick gassing in later stage in addition, fold and accomodate.

Compared with the prior art, the utility model has the advantages of: the airbag body can be folded when not inflated, so that the airbag is convenient to store and carry; the arrangement of the air bag nozzle is beneficial to guiding air into the air bag body; the air bag mouth is closed under the action of the air bag cover, so that the outflow of air in the air bag body is avoided, and the air bag is convenient to inflate when being opened; the diameter of the vent hole is not shorter than 10mm and not longer than 30mm, and the purpose of quick inflation can be achieved in a short time during inflation; the arrangement of the tether is convenient for hand grasping; the utility model discloses portable, safe in utilization just aerify very fast.
