Abstract

An emergency-inflated life-saving coat relates to life-saving technology field, which comprises a life-saving coat 1 and an inflating device consisting of a compression gas-tank 4, an inflation valve 9 and a switch part 20 and being able to be installed on the life-saving coat, wherein, the compression gas-tank 4 is provided with an inflating valve 5; inside the cavity of the compression gas-tank a cone valve core 7 pressed on a spring 8 is arranged with the conical surface contacted and sealed with the cone internal mouth 6 of the cavity; one end of the inflation valve 9 is butt jointed with the inflating valve 5 of the compression gas-tank, while the other end is connected with the inflating mouth 13 of the life-saving coat; the inflation valve intracavity contains an opening opposite to the inflating valve 5 and pressed on a spring 12 with a cone front end and the conical surface contacted and sealed with the cone internal mouth of the valve cavity, as well as a valve core 10 with a central inflation channel 11; the movement of the valve core 10 is controlled by the switch part 20 arranged inside an inflation valve body bulge 10. The utility model is able to be pulled on as a waistcoat and when in emergency, just screw the compression gas-tank and undraw the switch ring to inflate, thereby being characterized by convenient use, fast emergency reaction with remarkable time saving.

Description

The emergency pneumatic life jacket

Technical field: the utility model relates to the lifesaving appliance technical field, rapidly aerated life jacket when being a kind of emergency situation.

Background technology: existing life jacket can divide inflation basically and fill two kinds of light body expanded materials, and existing inflatable lifejacket generally is to be given by fixing gas filled device to inflate, this is in inflation one by one more in case of emergency, quality time will be incured loss through delay, and if the gas of substituting the bad for the good is in advance deposited standby or dress, volume is big and need account for than large space, and wears life jacket when no emergency situation, and is unnecessary again.

Summary of the invention: the purpose of the utility model, be to provide a kind of emergency pneumatic life jacket, the related personnel is in case of emergency inflated by wearer oneself on one's body can being through as wearing the clothes fast, can race against time, and is easy to use.

For reaching the technical measures that above-mentioned purpose takes is that the emergency pneumatic life jacket comprises life jacket 1, and can be loaded on the gas filled device that is made of compression gas tank 4, charge valve 9 and switch block 20 on the life jacket; The compression gas tank 4 of described gas filled device has valve nozzle 5, and the taper valve inside 7 that is pressed on the spring 8 is arranged in its cavity, its conical surface and 6 contact seals of cavity taper internal orifice; The charge valve 9 of described gas filled device, the one end can dock with the valve nozzle 5 of compression gas tank, its other end can be connected with life jacket inflation inlet 13, the charge valve inner chamber have be pressed on the spring 12, its front end is tapered, its conical surface can be with the contact seal of valve pocket taper internal orifice, corresponding to the opening of valve nozzle 5, have the spool 10 of center filling channel 11; Spool 10 moving are controlled by the switch block of being located in the inflation valve body salient 10 20.

This emergency pneumatic life jacket can be used as on one's body vest is through, and the compression gas tank of screwing on during emergency situation, to draw back the switch ring inflatable, easy to use, and emergency reaction is fast, can strive for the quality time.

Description of drawings:

Accompanying drawing 1 the utility model organigram

Accompanying drawing 2 the utility model gas filled device constructional drawings

The specific embodiment: following, structure and the condition of service to the utility model is described further in conjunction with the accompanying drawings.

Shown in accompanying drawing 1 the utility model organigram, this life jacket 1 is as vest back of the body body, on one's body shoulder harness 3 and front cingulum 2 be dressed in, different with common life jacket is, increased by a cover quick air-inflating apparatus, charge valve 9 and switch block 20 thereof that it comprises compressed air reservoir 4, docks with it, charge valve separates with life jacket, it can be fixed on the life jacket fast when wearing life jacket, and the charge valve end is docked with life jacket inflation inlet 13.Compression gas tank 4 also separates with charge valve 9, during use can with the charge valve rapid abutting joint, the utility model is to adopt the butt joint of rib-loop form, also can adopt and revolve the butt joint of card form, during emergency situation, it is the life jacket inflation that Drawing switch ring 18 can be opened charge valve.Accompanying drawing 2 is depicted as the gas filled device constructional drawing, comprise compression gas tank 4 and charge valve 9 two parts, compression gas tank 4 has valve nozzle 5, the taper valve inside 7 that is pressed on the spring 8 is arranged in its cavity, its conical surface and 6 contact seals of cavity taper internal orifice, be sealing state after the gas storage, get final product outside exhaust in the chamber as if valve inside 7 is pressed; Charge valve 9, the one end can dock with the valve nozzle 5 of compression gas tank, and its other end can be docked and connected with life jacket inflation inlet 13, and the charge valve inner chamber has the spool 10 that is pressed on the spring 12.Its front end is tapered, its conical surface can with the contact seal of valve pocket taper internal orifice, spool 10 front ends are corresponding to the opening and the spool 7 of valve nozzle 5, spool 10 has center filling channel 11, when spool is moved to the left its most advanced and sophisticated unseat the valve and chews 5 spool 7, pressurized air in the compression gas tank will be the life jacket inflation by valve nozzle 5 heart filling channel 11 and right half valve pocket among spool 10.Spool 10 moving are controlled by the switch block of being located in the inflation valve body salient 14 20, switch block 20 comprises and is in salient 14 inner chambers, be pressed on the switch spool 16 on the spring 17, itself and connect draw ring 18 2 parts, in the groove 15 of mobilizable embedding molding of charge valve cores 10 sidewalls of tack one end of switch spool 16, the start-stop action is used, its another conical end connects the external draw ring 18 of salient through stay cord 19, it is tapered that the salient inner chamber is drawn an end of stay cord, when pulling spool 16 moves down, its butt end breaks away from groove 15, molding of charge valve cores 10 will move to left and open valve nozzle 5, and the conical surface of its conical end and its chamber inner conical end forms contact seal in case leak-stopping gas.Compression gas tank is that life jacket charges gas, and the two will be in the air pressure balance state, and this moment, compression gas tank can not take off, and will together produce buoyancy with life jacket.After life jacket uses up, compression gas tank is taken off, charge valve also can take off from life jacket, takes off the back and will spool presses in 10 with push rod, makes switch spool 16 embed locking in the grooves 15, uses during in order to next emergency situation.
