CN2703717Y - Automatic air-expanding type safety lifebelt on water - Google Patents

Abstract

The utility model discloses an automatic air-expanding type safety lifebelt on water, including a grenade-shape housing which is healed up by tow half clacks and is buckled by a buckle clack. The end of the housing is provided with a locking setting element, and an air-bag heat pressing connecting air intake valve which is folded is arranged in the housing; the air-expanding automatic inflating device of the air bag is connected with the air intake valve, and an air cylinder which is filled with carbon-dioxide compressed gases in advance is screwed tightly on the automatic inflating device; the air bag is a single air bag and forms a lecotropal safety loop. The design improves the structure of the housing and adopts a reasonable automatic inflating device; the automatic air-expanding type safety lifebelt on water has simple structure, convenient assemblage and use and automatic, quick, safe and reliable inflating; the air-expanding process does not burn and has no temperature, so the human body and devices can not be scalded; after air expanding, the air bag can disengage from the housing completely; meanwhile, the automatic air-expanding type safety lifebelt on water has small volume, reasonable weight and contour design, so the automatic air-expanding type safety lifebelt on water is convenient to be cast; the cast is characterized in far cast, exact point of fall and high life-saving efficiency, etc, and thus the automatic air-expanding type safety lifebelt on water is suitable for all water areas to use.

Description

Automatic air heave type water safety circle

Technical field

The utility model relates to the fast automatic gas filed emergency survival safety collar waterborne of a kind of energy.

Background technology

It is a lot of to be widely used in the equipment that the single lifesaving waterborne such as river, river, lake, sea, reservoir, bay under the various climatic conditions uses, as belong to the inflatable life that having of air heave type lifesaving adopted the hydraulic type switch, this equipment has certain requirement to environment for use, promptly must certain under water degree of depth, must reach behind the enough pressure could energized, lights inflation, inflationtime is slower, its sensitive member is spring and rubber, and is easily aging, all can reduce its reliability; Also have a kind of " air heave type saving bar automatically " as Chinese patent 96205499.2, adopt water as medium, make the short circuit energized light inflation, inflatable speed is fast, but will regularly replace battery, and is also inconvenient.The inflatable source of the gas of above-mentioned two kinds of schemes all is to adopt solid nitrogen to light the back to produce the high pressure nitrogen inflation, its volume is bigger, and weight is heavier, and cast and drop point are all not ideal enough, temperature is higher during the inflatable of burning in addition, so must in water, use, just in case miss inflatable by land, just burn easily human body and air bag, dangerous, unreliable, in a word, gas filled device is very unreasonable.Remove this, its shell is an integral type, the inflatable air bag just can wash out top cover after must reaching certain pressure, go out shell, but, can't all break away from shell because of the relation of line construction, its complex structure, assembling and use inconvenience since weight big, influence cast and accurate drop point, so influence lifesaving efficient.

Summary of the invention

Technical problem to be solved in the utility model be to overcome the defective of prior art and provide a kind of simple in structure, assembling, easy to use, cast far away, accuracy in placement, gas filled device are reasonable, the automatic inflatable of air bag rapidly, automatic air heave type water safety circle that the lifesaving rate is high.

Technical matters of the present utility model is achieved through the following technical solutions:

A kind of automatic air heave type water safety circle, it comprises shell, is provided with in the shell through folding air bag, with air bag bonded assembly inflatable parts, it is characterized in that described shell is closed up with button lobe snapping by two and half lobes and be grenade shape that its afterbody is provided with the locking positioning element; Described air bag is single air bag, and hot pressing is connecting air inlet valve, and the valve end is connected with the leakproof nut, forms the horseshoe type safety collar after the inflatable; Described and air bag bonded assembly inflatable parts are self-fillers, and this device is connected with air inlet valve, the gaholder that the carbon dioxide of substituting the bad for the good is in advance compressed gas again spinning on self-filler.

The locking positioning element of described shell afterbody promptly is provided with the jam nut and the spinning of locking the two halves lobe at afterbody and also regulates the set screw that holds out against gaholder on jam nut.

Be provided with hot pressing bonded assembly lobe band around the described air bag.

Compared with prior art, the utility model has improved containment structure and has adopted rational self-filler and gaholder as the inflatable parts, it is simple in structure, assembling and easy to use, inflation automatically, fast, safely, reliably, temperature is not burnt, do not had to the inflatable process, can not burn human body or equipment, air bag after the inflatable can break away from shell fully, have also simultaneously that volume is little, weight and configuration design rationally be convenient to throw, have characteristics such as throwing is far away, accuracy in placement, lifesaving efficient height, be suitable for all waters and use.

Description of drawings

Fig. 1 is an overall structure scheme drawing before the utility model entry.

Fig. 2 is the structural representation after the air bag inflatable.

Fig. 3 is the F place structure enlarged drawing of Fig. 2.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Figure 1-3, automatically the shell 5 of air heave type water safety circle is made with the ABS engineering plastics, close up by two and half lobes, utilize the elasticity snapping of material to be grenade shape with siamesed male and female buckle lobe, be convenient to assembling, hand is taken, is thrown, its afterbody is provided with the locking positioning element, the jam nut 6 that promptly comprises locking two halves lobe, set screw 7 spinnings are also regulated the gaholder 4 that holds out against in the shell on jam nut, prevent the upper and lower play of gaholder, label 2 on shell simultaneously, and be provided with anti-slip tank at the hand-holding part of shell.

Through folding air bag 3 is single air bag, be pressed into high frequency heat after cutting by the PU polyurethane cloth of salmon pink or the PVC of high-low temperature resistant, form the horseshoe type safety collar after this air bag inflatable, end hot pressing at air bag is connected with air inlet valve 9, and connect sealing with leakproof nut 10, the self-filler 1 of air bag inflatable is connected on the air inlet valve, gaholder 4 oral areas of the carbon dioxide of substituting the bad for the good in advance compression gas are threaded, spinning is on self-filler 1, around air bag, be provided with hot pressing bonded assembly lobe band 8 on the chimb simultaneously, help the drowning people that safety collar is pulled to and pack into health enforcement relief at one's side, above-mentioned all parts are all built-in in shell 5.Entry rear gasbag 3 inflatable in 5 seconds finishes, and shell 5 is opened into two lobes simultaneously, and air bag just emerges after breaking away from shell, and its buoyancy enough satisfies the needs of single emergency survival.

Self-filler of the present utility model 1 adopts 200420019957.2 " the waterborne dual-purpose lifesaving gas filled device " of the applicant in first to file, the critical component of this device is lotus flower head and the water-soluble sheet that detonates, the water-soluble sheet that detonates is to be solidificated in the lotus flower head after mixing with the special good chemical material of multiple water absorbing properties, gland is lived the lotus flower head rest, the water-soluble sheet that detonates is the solid shape under the normality in the lotus flower head, after meeting water, the water-soluble sheet that detonates dissolves rapidly in second at 2-3, make push rod lose supporting role, pressure lower push rod bump striker at spring, crashed through the seal cover cap on the gaholder, made it automatically rapidly to connected airbag aeration.
