Abstract

The utility model relates to an automatic inflatable life jacket for swimming, which is an automatic inflatable lifesaving device for swimming. The utility model is characterized in that the automatic inflatable life jacket for swimming comprises a plastron with two gas chambers and a gas generator which is communicated with the two gas chambers, wherein, the lower body of the gas generator is a cavity for containing liquefied gas and is provided with a gas feeding valve. The upper body of the gas generator is provided with an inflating valve and a gas passage which is communicated with the gas chambers, and the gas passage is provided with a gas releasing valve. When used as a buoy, the utility model is both suitable to be used by swimming beginners and be used for self aid in emergency. Particularly, the gas generator has small volume, fast inflating speed, sufficient gas source and repeatable use for many times.

Description

Quick automatic inflatable life jacket for swimming

The utility model relates to a kind of can automatic gas filed swimming lifesaving device, specifically be improvement to existing inflatable swimsuit.

Existing a kind of automatic inflation swimsuit, its structure is that the leakproofing material of hollow interlayer is made Swiming waistcoat, adorns a gas generator on it, gas is to be generated by calcium carbide in the gas generator and water generates chemical reaction.This swimsuit both can be swum, can save oneself again, and modern design, but the volume of gas generator is bigger, and calcium carbide and water speed of response are slow, and residue is difficult to handle inconvenient repeated usage.

The purpose of this utility model is exactly the improvement to existing inflatable swimsuit, and a kind of swimming of both being convenient to is provided, and can save oneself again, and it is little that gas generator also has a volume, the source of the gas abundance, and can repeat nonexpondable characteristics.

Solution of the present utility model is: be made up of the corselet of containing two air chambers and a gas generator that is communicated with two air chambers, wherein the structure of gas generator is: lower body is a cavity of containing liquid gas, be provided with and add air valve, charging valve is equipped with in the upper body, have the air flue that is communicated with air chamber, aie escape valve is housed on the air flue, and its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, the feature of the fast automatic inflation swimming lifesaving corselet that the utility model provides is made up of the corselet of containing two air chambers (2) and a gas generator (3) that is communicated with two air chambers (2), and the gas that produces in the gas generator (3) can put on the air to two air chambers (2).Referring to Fig. 2, Fig. 3, the structure of gas generator (3) is: lower body (13) is a cavity of containing liquid gas, be provided with and add air valve (16), by this valve (16), can be in the cavity of lower body (13) pouring in liquid gas, charging valve is equipped with in upper body (12), has the air flue that is communicated with air chamber (2), and aie escape valve (11) is housed on the air flue, if when needing inflation, or in water, run into dangerous situation, as long as open charging valve, the liquid gas in lower body (13) cavity will enter air flue from valve rapidly under pressure, be vaporized simultaneously, become gaseous state gas, be full of air chamber (2), produce buoyancy.After finishing using, the aie escape valve on the air flue (11) is opened, the gas in the air chamber (2) will all be emitted.Because two air chambers of the present utility model are not connected, when one of them air chamber gas leakage, as long as the gas off-take of the side of will leaking gas stops up, another air chamber can normally be inflated, and still can play certain lifesaving protective effect.Charging valve of the present utility model comprises upper valve rod (21) and lower valve rod (19), spring (17) is housed on the lower valve rod (19), have locked groove (10) on the upper valve rod (21), spring (15) is housed on the upper body (12), locking plate (14), other is equipped with seal ring (18), (20), when needs inflation Open valve, make upper valve rod (21) promote lower valve rod (19) to moving down, separate with seal ring (18) lower end of lower valve rod (19), valve open, locking plate (14) in upper body this moment (12) enters in the locked groove (10) of upper valve rod (21) under spring (15) effect, to go up, lower valve rod (21), (19) locking makes valve be in opening, after gas is full of, press locking plate (14) with have gentle hands, on, lower valve rod (21), (19) reset under spring (17) effect, valve is closed again, seal ring (20) prevent that as the time spent gas of valve opening from running out of from upper valve rod (21).Lower body of the present utility model (13) is provided with reinforced rib, makes lower body (13) to high-pressure liquid gas certain holding capacity be arranged.The length of connecting band of the present utility model (7) can be regulated with different link (6) connections by hook (1), and the length of braces (8) can be regulated by knot that can be undone by a pull.

The fast automatic inflation swimming lifesaving corselet that the utility model provides is the improvement at existing inflation swimsuit, it both had been suitable for the beginning swimmer as a kind of buoyancy device and had used, be suitable in danger saving oneself and flood-fighting again, corselet formula structure makes volume small and exquisite, does not influence strokes, especially the gas generator volume is little, inflation is fast, the source of the gas abundance, but repeated multiple times is used, therefore the utility model is simple in structure, has more comfort feature and practicality.

Accompanying drawing has been represented specific embodiments of the present utility model.

At first accompanying drawing is described:

Fig. 1 represents integral structure scheme drawing of the present utility model;

Fig. 2 represents the constructional drawing of gas generator;

The A-A cutaway view of Fig. 3 presentation graphs 2.

According to embodiment shown in the drawings, gas generator (3) places the bag (4) at corselet middle part, the pkt. flap (5) that band slide fastener or velcro are arranged on the bag (4), in order to be applicable to the requirement of various ages and stature, corselet can be made all size, and connecting band of corselet (7) and braces (8) are all made with elastic cord, the afterbody of connecting band (7) is respectively equipped with plurality of hanging (6) and hook (1), braces is equipped with knot that can be undone by a pull on (8), corselet can or be made the back gluing with the gluing nylon taffeta with colored plastic film cut-parts hot pressing monolithic molding and be formed, and makes with colored nylon silk or other non-suction cloth with interlayer form formation two air chambers (2) or two latex balloon overcoats.The upper body (12) of gas generator (3) and lower body (13) are by the thermoplastic plastic compression molding, for observation adds tolerance, lower body (13) is transparent, on upper valve rod (21), be connected with handle (9), aie escape valve (11) adopts the air bleed screw structure, and the overall volume of gas generator (3) is 60 * 20 * 53 millimeters.
