Abstract

The utility model provides a portable automatic inflatable life buoy, comprising a ring airbag, an inner nut and a plastic film bag with hydrochloric acid. The utility model is characterized in that the inner nut is bonded and fixed at the inner wall of the ring airbag, an additional sleeve is provided with a leaking hole, the upper end of the sleeve is connected with the inner nut thread is arranged at the bottom, the plastic film bag is covered inside the sleeve, the port of the bag is outward covered at the sleeve, a soft glue seal which bottom is fixed with a stamp pole is covered at the sleeve port, the upper thread is clamped and fixed with a fixed ring cover, the top thread of the fixed ring cover is fixed with a cover cap, and some chemical that can react with hydrochloric acid to produce gas is positioned inside the ring airbag. The utility model as an aquatic life-saving emergency supplier is usually folded and stored, and is portably carried; the cover cap is turned on in case of an accident, the stamp pole is pressed to puncture the plastic film bag, and then the hydrochloric acid flows out at once to react with the chemical in the ring airbag to produce a plurality of gas, so that the ring airbag expands rapidly and is filled with air, realizing the object of self-help in trouble.

Description

The portable buoy quoit of automatic inflation type

Affiliated technical field

The utility model provides a kind of automatic inflation type portable buoy quoit, belongs to lifesaving appliance technical field in the water.

Background technology

Along with waterborne traffic, transportation and Tourism development, by ship or the personnel of operation at sea more and more, overwater accident happens occasionally.Buoy quoit is as security apparatus in the water, need to use after the inflation in advance, because it is bulky, it is very inconvenient to carry, can not each passenger wear one, in case just be difficult to when having an accident in time provide and give the passenger, bring into play its lifesaving effect, rescue the people at some divings simultaneously, drag for place such as thing under water and also be difficult to play a role.At above-mentioned situation, at present also relevant for the technology report of inflatable life preserver automatically, as Chinese patent communique disclosed utility model patent on July 15th, 1992: the water survival circle, the patent No.: 91229694, constitute by gas generator and annular air pocket.And gas generator is the fluid reservoir by the band edge lid, charge valve, seal ring, self-locking spring; Liquid-filling valve, seal ring and retracing spring constitute.The outside face of annular air pocket is with at least one strip hard fibre snap-fastener, and before annular air pocket was inflated, this water survival circle can be tightened the waist the user.This water survival circle is safe and reliable, can not touch pneumatic element because of misoperation.Defective is a complex structure, and buoyancy is little, and its in-use performance needs further improvement.

The utility model content

The purpose of this utility model provide a kind of can overcome above-mentioned defective, simple in structure, easy to operate, be easy to carry, the portable buoy quoit of automatic inflation type of excellent working performance.Its technical scheme is:

Comprise ring-shaped gasbag, inner nut and be loaded with the plastic film bag of hydrochloric acid, it is characterized in that: inner nut is bonded and fixed on the inwall of ring-shaped gasbag, its upper end of sleeve that is provided with small opening bottom setting up is threaded with inner nut, plastic film bag is sleeved in the sleeve its port and turns up and be enclosed within on the sleeve, the bottom is fixed with the flexible glue that stabs bar seals and is sealed on socket port, the upper end screw thread is compressed with fixedly ring cowling, fixedly the screw top of ring cowling is fixed with block, and being equipped with in the ring-shaped gasbag to react with hydrochloric acid produces the pharmaceutical chemicals of gas.

The portable buoy quoit of described automatic inflation type, it is flower-shaped that the bottom of stamp bar is " ten " word, presses close to the bottom of plastic film bag.

The portable buoy quoit of described automatic inflation type, ring-shaped gasbag comprise the inner tube of a tyre that cover tire and flexible plastic film are made, and inner nut is bonded and fixed on the inwall of the inner tube of a tyre, and its top leans out cover tire.

The utility model is as emergency survival articles for use waterborne; stored collapsed at ordinary times, volume is little in light weight, is easy to carry and does not influence user's normal activity; in case meet accident during accident; the block of outwarding winding is pushed and is stabbed bar plastic film bag is poked, hydrochloric acid promptly flow out with ring-shaped gasbag in pharmaceutical chemicals react and produce a large amount of gas; make the ring-shaped gasbag inflation of expanding rapidly; generation is equivalent to the buoyancy of 50 times of left and right sides buoy quoit own wts, and the wearer can swim in the water surface after falling into water, obtains relief.The utility model also can be used for diving and rescues the people, drags for place such as thing under water, wear down water by the scuba diver, wait to find outward winding after the target block, push and stab bar plastic film bag is poked, ring-shaped gasbag will be inflated automatically, i.e. floatability water outlet face, the utility model also can be used as the relief articles for use of ship in addition, make big air bladder, be close to the hull both sides at ordinary times, in case run into strong wind, intake, just control ring-shaped gasbag when leaking and inflate automatically, can increase the buoyancy and the stability of ship, application is extensive.
