Abstract

A rescue suit relates to the water rescue equipment technical field. The technic proposal is that the suit is communicated with a compression chamber, solid or liquid substances which are in gaseous states under normal pressure are placed in the compression chamber; a switch is arranged between the compression chamber and a suit to control the connection and cutoff between the solid or liquid state substances in the compression chamber and the suit layer. The utility model utilizes the volume expansion principle when substances are changed from solid or liquid state into gaseous state to arrange the substances compressed into solid or liquid state in the compression chamber. When in use, the rescue purpose can be achieved; and when not charged with gas, the size is small, and thus not affecting the normal action of a user; when the product is used to rescue others, greater rescuing function can be achieved due to portability of the utility model which can reduce the energy consumption of the rescuer.

Description

Life combination suit

Technical field:

The utility model relates to water survival equipment technical field, refers in particular to a kind of life combination suit.

Background technology:

Life combination suit is usually used in water survival, or aquatic sports; At present, its structure is divided into two kinds substantially, and a kind of is to fill the buoyancy thing at double-ply life combination suit interlayer, relies on the buoyancy of internal buoyance thing, and the people is bubbled through the water column; Another kind is that the interlayer of life combination suit is inflated with manual type, and the buoyancy of gas is kept afloat the people; But the volume of above these two kinds of life combination suits is bigger, and is also comparatively heavy; Carry inconvenience, also be difficult to during use meet the demands; As in when swimming, for preventing unexpected generation, on one's body people can be through life combination suit, but, like this then because of the larger volume of life combination suit, can hinder the swimmer to move the performance of skill and level.

Summary of the invention:

The purpose of this utility model is to provide a kind of volume little, is easy to carry, the simple life combination suit of using method.

The utility model is achieved by the following technical solution: be communicated with compression chamber on the clothes, it is the solid-state or fluent of gaseous state that atmospheric pressure state is arranged in the compression chamber; The switch of solid-state or fluent and the switching of clothes interlayer in compression chamber and check room have a control compression chamber; Clothes can be bilayer or multilayer, sealing around the interlayer, and have a pore to be connected with compression chamber; Solid-state or fluent in the compression chamber can be compressed CO ₂, O ₂, N ₂Deng; Its air extractor duct is a double-decker, on internal layer and skin pore is arranged, and corresponding with it through hole is also arranged on the switch; Protruded out raised line on the internal layer of compression chamber, the outer and switch contact surface, also fluted on the switch, raised line and groove match when the switch open and close.

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 fluent in the compression chamber communicates with the clothes interlayer of normal pressure, and compressed solid-state or fluent expand into gas rapidly, and the clothes support is expanded, and its volume is become greatly, thereby the user is bubbled through the water column; Thereby, the utility model volume when not inflating is little, can reach its effect fully during use, comparatively convenient for the user, using method is simple, can not influence the user and move normally, succours other people carrying this product, also can reduce the physical consumption of self, bring into play bigger rescue effect owing to property easy to carry of the present utility model.

Description of drawings:

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

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model part sectional view.

The specific embodiment:

See accompanying drawing 1,2, be communicated with compression chamber 2 on the utility model clothes 1, it is the solid-state or fluent of gaseous state that atmospheric pressure state is arranged in the compression chamber 2; The switch 3 of solid-state or fluent and clothes 1 interlayer switching in compression chamber 2 and 1 in clothes have a control compression chamber 2; Clothes 1 can be bilayer or multilayer, sealing around the interlayer, and have a pore to be connected with compression chamber 2; Solid-state or fluent in the compression chamber 2 can be compressed CO ₂, O ₂, N ₂Deng; Its air extractor duct is a double-decker, on internal layer 21 and outer 22 pore 23 is arranged, and corresponding with it through hole 31 is also arranged on the switch 3; The internal layer 21 of compression chamber 2, outer 22 with switch 3 contact surfaces on protruded out raised line 24, also fluted 32 on the switch 3, raised line 24 and groove 32 match when switch 3 closures.

When using the utility model, earlier the utility model is worn on the body, when not needing, switch 3 cuts out by buoyancy; When need be by the buoyancy in the external world, switch 3 is opened, through hole 31 is communicated with pore 23, thereby make to be compressed into solid-state or liquid material in the compression chamber, become normal pressure (barometric pressure) state, thereby expand into gas rapidly, it is big that volume becomes, and clothes 1 support is expanded, and the user is bubbled through the water column; When needs utilize once more, have the compression chamber 2 of pressurized contents or press interior the pressure to irritate material to compression chamber 2 again as long as change.
