Abstract

The utility model discloses a lifejacket, and relates to the technical field of buoyant apparatus. The lifejacket comprises a lifejacket body, a compression chamber is arranged on the lifejacket body and communicated with the lifejacket body through pores, and the compression chamber is provided with a switch for controlling the pores. By utilizing the principle of volume expansion of matters when changing from solid state and liquid state into gas, the matters compressed into solid state or liquid state are placed in the compression chamber, and the purpose of life saving can be achieved when the matters are used; the volume is smaller when the compression chamber is not aerated, thus not affecting normal movement of the user; and when carrying the product for rescuing others, physical consumption of the user can be reduced due to the carrying convenience of the lifejacket, thus playing a greater role in rescue.

Description

Life jacket

Technical field

The utility model relates to a kind of life jacket, belongs to water survival equipment technical field.

Background technology

Life jacket is usually used in water survival and aquatic sports, and life jacket in the market is divided into two kinds substantially, and a kind of is at the inner buoyancy thing of filling of life jacket, relies on the buoyancy of internal buoyance thing, and the people is bubbled through the water column; Another kind is the interlayer aerification of life jacket, and the buoyancy of gas is kept afloat the people.In when swimming, for preventing unexpected generation, on one's body people can be through life jacket, traditional life jacket volume was big, was not suitable for carrying, and can hinders the swimmer to move the performance of skill and level, only suitable not natatory people.

The utility model content

The purpose of this utility model is: provide a kind of volume little, be easy to carry, easy to use and simple life jacket.

The scheme that its technical matters that solves the utility model adopts is: life jacket comprises the life jacket body, and the life jacket body is provided with compression chamber, and compression chamber is communicated with the life jacket body by pore, and compression chamber is provided with the switch of control pore.

As preferably, compression chamber is connected with the life jacket body with outer field double-decker by comprising internal layer, is respectively equipped with coaxial pore on internal layer and the skin, and switch is between internal layer and skin, and switch is provided with through hole.

As preferably, switch is provided with raised line, is provided with between the internal layer of compression chamber and the skin and the corresponding groove of raised line.

The utility model utilizes material by cubic expansion principle solid-state, when liquid state becomes gaseous state, is compressed into solid-state or liquid material in that compression chamber is built-in; When switch open, the solid-state or liquid special material in the compression chamber communicates with the clothes interlayer of normal pressure, and compressed solid-state or liquid special material expand into gas rapidly, and the clothes support is expanded, and makes its volume become big, thereby the user is bubbled through the water column; Thereby, the utility model volume when not inflating is little, comparatively convenient for the user, using method is simple, can not influence the user moves normally, succour other people carrying this product, also because property easy to carry of the present utility model and can reduce self physical consumption is brought into play bigger rescue effect.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model part sectional view.

Wherein: 1 is the life jacket body, and 2 is compression chamber, and 3 is switch, and 21 is internal layer, and 22 is outer, and 23 is pore, and 24 is groove, and 31 is through hole, and 32 is raised line.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

As shown in Figure 1 and Figure 2, life jacket is made up of life jacket body 1, life jacket body 1 is provided with compression chamber 2, compression chamber 2 is communicated with life jacket body 1 by pore 23, compression chamber 2 is provided with the switch 3 of control pore 23, and compression chamber 2 is connected with life jacket body 1 with the double-decker of skin 22 by comprising internal layer 21, is respectively equipped with coaxial pore 23 on the internal layer 21 and outer 22, switch 3 is between internal layer 21 and outer 22, and switch 3 is provided with through hole 31.Switch 3 is provided with raised line 32, is provided with raised line 32 between the internal layer 21 of compression chamber 2 and outer 22 and thinks corresponding groove 24.

Be equipped with in the compression chamber 2 and be the solid-state or fluent of gas under the normality, it can be compressed H2, O2 etc.

When using this life jacket, but life jacket is worn on the body free swimming, when causing danger or other reason need be by the buoyancy in the external world time, starting switch 3 makes through

hole

31 and 23 coaxial being connected of pore thereby raised line 32 is moved in groove 24, make compression chamber internal solid or liquid material, become normal pressure (barometric pressure) state, thereby expand into gas rapidly, it is big that volume becomes, life jacket body 1 is full of, reaches buoyancy.

In the utility model, the mutual action of raised line 32 and groove 24 except adopting the draw-in groove fit system, can also adopt the fit system of helicitic texture.
