Description

Mechanism for falling and standing life jacket

Technical Field

The invention relates to the technical field of life-saving equipment, in particular to a mechanism for falling and standing a life jacket.

Background

A life jacket, also called a life vest, is a life-saving garment, is designed like a vest, is made of nylon fabric or chloroprene rubber, buoyancy material or inflatable material, reflective material and the like, is one of life-saving equipment on ships and airplanes, is generally vest-type, is made of foam plastic or cork and the like, has enough buoyancy when being worn on a body, and enables a person falling into water to float out of the water surface.

Traditional life vest is when normal use, because its size varies from person to person, make partial thin personnel's life vest comparatively loose, lead to the life vest making the personnel that fall into water float the surface of water, because the armpit can receive great upwards buoyancy, make the life vest appear the condition that drops easily, personnel in addition lead to falling into water under the condition such as the wave is beaten and is patted, the condition that the personnel that fall into water fell down dizzy easily appears, under the condition of no external force balance, the personnel face condition down that falls into water appears easily, lead to having the potential safety hazard that drowning stifled.

Disclosure of Invention

Aiming at the defects of the existing life jacket in the use process in the background technology, the invention provides the falling and rising mechanism of the life jacket, which has the advantages of falling water fastening and falling and rising, and solves the technical problem that the life jacket is easy to fall off or has potential safety hazard when no external force is balanced in normal use.

The invention provides the following technical scheme: the utility model provides a mechanism of rising for a short time of life vest, includes the cloth body, the lower extreme fixedly connected with of cloth body is foam block down, the upper end fixedly connected with of cloth body is foam block, and the lower extreme of going up foam block is "Y" style of calligraphy, the middle part fixedly connected with of cloth body is located the folded layer between foam block and the last foam block down, the inner chamber of folded layer is provided with the gas storage chamber, the middle part of going up foam block lower extreme is provided with the pressure boost chamber, the inner chamber activity of cloth body middle part has cup jointed the movable block, the movable block is "worker" style of calligraphy, and upper and lower extreme is located gas storage chamber and pressure boost intracavity respectively, gas storage chamber and pressure boost intracavity fill have gas, the inner chamber fixedly connected with of cloth body is located the pressure boost pad of pressure boost intracavity side, gas storage chamber and pressure boost chamber are through being located the air vent intercommunication in the middle part outside of movable block.

Preferably, the diameter of lower foam piece is greater than the diameter of last foam piece, the folded layer is made for soft air-tight material, the lower fixed surface in the movable block outside is connected with the bellows, and the lower extreme of bellows and the bottom surface fixed connection in pressure-increasing chamber, the middle part of the cloth body is seted up and is located the income basin of bellows lower extreme, and goes into basin and external intercommunication, the middle part fixedly connected with that goes into the basin opens and close the piece, the middle part activity that goes into the basin has cup jointed and is located two and open and close the piece between the piece relatively and seal the piece.

Preferably, the lower end of the outer side of the lower foam block is fixedly connected with a pull rope, and the other end of the pull rope is fixedly connected with the middle part of the movable block.
