Abstract

The utility model relates to a water lifesaving device which is especially suitable for the fast rescue of a drowning swimmer. The water life buoy is composed of an air generator and an annular air bag, wherein the air generator is composed of a liquid storing chamber with an end cover, an inflating valve, a sealing ring, a self-locking spring, a liquid injecting valve, a sealing ring and a restoring spring, and at least one sliver-shaped fastener made of hard fibre is attached to the outer surface of the annular air bag. The water life buoy can be fastened on the waist of a user before the annular air bag is inflated. The water life buoy is safe and reliable, and the annular air bag can not be touched by misoperation for inflating the annular air bag at improper time. Simultaneously, the water life buoy can be worn like a waistband.

Description

Underwater life buoy

The utility model relates to a kind of aquatic life-saving equipment, is specially adapted to the self-fast aeration rescue of swimmer when drowned.

It is 88216830 instant inflation swimming life-saving belt that Patent Office of the People's Republic of China discloses a patent No..This life belt is to utilize butane to make aerating agent and utilize the topping up structure of lighter to carry out fluid injection and gas filed.This lifesaving appliance is simple in structure, can repeated usage, and aeration speed is fast.But its shortcoming is: (1) this swimming life-saving belt is easy to generate misoperation.Because its gas-filled switching tube is a large tracts of land pressing plate, and contact with the person, when the user swims in the water, accidentally just might touch gas-filled switching tube, life belt is inflated at once, this has just run counter to the purpose of using this life belt; (2) air bag of this device is made the shape that is fit to around human body trunk top, and this equals the people and puts on a thing that similar vest is the same, and it not only can influence the swimming activity, and the people is felt under the weather.

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of water survival circle is provided.When swimming in the water,, just can not touch pneumatic element, make the buoy quoit inflation and generation buoyancy so long as not conscious action for the user.

Another purpose of the present utility model is to make this buoy quoit before inflation, can tie up on user's the waist as waistband, can overslaugh not swim in the water.

The utility model can be realized by following measure:

This water survival circle is made up of the gas generator annular air pocket, its feature is: gas generator is by the fluid reservoir of with closure, the fluid injection that is contained in fluid reservoir one end is cut down, seal ring, the inflation that is contained in the fluid reservoir other end is cut down, seal ring is fixed on to inflate the self-locking spring that cuts down and be contained in cutting down with fluid injection for inflation in the fluid reservoir and cuts down shared retracing spring formation; At the outside face of annular air pocket, have a strip hard fibre snap-fastener at least, make annular air pocket before inflation, by strip hard fibre snap-fastener this water survival circle is fastened waist the user.

Description of drawings is as follows:

Structural representation when Fig. 1 is inflating for the utility model water survival circle;

Fig. 2 is that this water survival circle is before inflation, by strip hard fibre snap-fastener and the folded state scheme drawing adjustable according to user's waistline.

The utility model is described in further detail below in conjunction with embodiment:

Among the figure 1 is gas generator, and 3 for having the fluid reservoir of seal cover cap 7, and it is made by transparent plastics, so that injection butane amount of liquid what are observed; A fluid injection is housed near the center of fluid reservoir right-hand member cuts down 8, a boss and a L shaped reservoir channel have been cut down in this fluid injection, the seal ring made from rubber 9 is by the firm the inside that is bonded at fluid reservoir of lining cement, near the end cap center of fluid reservoir left end, there is the inflation of a band boss and H shaped inflatable passage to cut down 4, the inner end that is bonded at end cap that rubber seal 5 usefulness lining cements are firm, cut down an end of relative boss in inflation and fix a U-shaped from snap 6, retracing spring 10 is contained between inflation is cut down and fluid injection cuts down, it forces two to cut down being pressed on separately the seal ring, so that it is close in fluid reservoir that butane liquid is sealed tightly simultaneously.2 for rubber, plastic cloth or scribble the annular air pocket that the fiber cloth of resin is made, the bottom of fluid reservoir and end cap, on the firm outside face that is bonded at annular air pocket of sealant, strip hard fibre snap-fastener, can also can use two or three with one, be bonded at the outside face of annular air pocket with lining cement, this snap-fastener is used to adjust the size of water survival loop diameter, so that failure-free ties up on user's the waist.When the user faces a danger in water need be by the buoyancy of water survival circle the time, press the inflation of a bottom end cover end to cut down as long as press...with one's finger, make this boss that cuts down leave seal ring, butane blue gas in the fluid reservoir will pass through H shape passage, and the air-filled pore of end cap bottom, the corresponding induction opening of air-filled pore bottom end cap on annular air pocket charge into annular air pocket rapidly.Meanwhile, the end of U-shaped self-locking spring enters in the annular groove 12, stops inflation to be cut down and gets back to original position.When not using this water survival circle, can open the air bleed hole on annular air pocket, allow the butane gas exhaust to atmosphere; When using this water survival circle, the long-neck fluid injection end of available butane liquid storage cylinder is aimed at the reservoir channel that the end is cut down in fluid injection, injecting liquid cuts down and makes its boss leave seal ring, then butane liquid just is injected in the fluid reservoir, when fluid injection is cut down boss and is left seal ring, the other end 14 that fluid injection is cut down pushes away the end 15 that inflation is cut down, force the end of self-locking spring to break away from annular groove to remove the self-locking state that inflation is cut down, at this moment the boss that inflation is cut down makes the butane liquid of fluid reservoir not enter in the annular air pocket under action of reset spring again.When fluid injection finishes, withdraw from the butane liquid storage cylinder, fluid injection is cut down under action of reset spring, and boss and its seal ring are fitted tightly, and the butane liquid of injection just is enclosed in fluid reservoir.The last air bleed hole of sealing annular air pocket again; The waist that this water survival circle is lain in the user just can safe having swum in the water.

The utility model compared with prior art has following advantage:

1. owing to the inflation of the utility model water lifebelt is cut down in the housing that is hidden in end cap, so, the user Shi Buhui that swims in the water touches inflation and cuts down, only have when drowned and just use finger when seeking to succour and touch this inflation and cut down, make the butane liquid in the fluid reservoir reach the purpose that buoyancy is provided to the annular air pocket inflation.

2. this water lifebelt can tie up on user's the waist as waistband before inflatable lifesaving, and is both attractive in appearance, the again activity of not overslaugh user in water.

Claims

1, a kind of water survival circle is specially adapted to the self-fast aeration rescue of swimmer when drowned, and it is to be made of gas generator 1 and annular air pocket, it is characterized in that:

(1) described gas generator 1 is the fluid reservoir 3 by with closure 7, the fluid injection that is contained in fluid reservoir one end cuts down 8, seal ring 9, and the inflation that is contained in the fluid reservoir other end cuts down 4, seal ring 5, be fixed on inflation cut down self-locking spring 6 on 4 and inflation cut down 4 and fluid injection cut down 8 shared retracing springs 10 and form;

(2) on the outside face of described annular air pocket 2 with at least one strip hard fibre snap-fastener, before annular air pocket 2 inflations, make buoy quoit can fasten waist the user.
