Abstract

The invention discloses a fastening life belt, and belongs to the field of lifesaving tools. The fastening life belt can provide movement freedom for people, and meanwhile, provides life-saving protection in time. The technical scheme is realized in the way that the fastening life belt comprises a hollow annular belt with good flexibility, wherein an opening is formed in the outer wall surface of the belt, a spherical-segment-shaped valve box with a valve chamber is adhered to the opening; a button is arranged in the center of the outer surface of the valve box; a pressure spring is clamped below the button in a sleeving manner; a plurality of air holes are distributed in the valve bottom of the valve box; a thin film covers each air hole; meanwhile sodium peroxide is placed in the valve chamber.

Description

Tighten life belt

Technical field

The invention belongs to life preserver field, specifically refer to and tighten life belt for emergency drowned in water.

Background technology

Swimming exercise, aquatic sports, the activity in water such as to speedily carry out rescue work in water is recurrent activity in social life, the danger of very easily drowning in such a case, in order to safety sometimes people have the buoy quoit of the circle of inflation or life jacket in putting to prevent the generation of this danger, but, such dress too increases the movable resistance of people in water while providing certain safety control for people, decrease action radius, limit some freedoms of action, particularly amusement in for water, play in the non-professional water went swimming activity of character more aobvious outstanding, so, in water in the modern life, movable people need a kind ofly not only can to provide safety control when needed but also can not affected as much as possible or few impact limits so a kind of novel life preserver of freedom of movement in water less.

Summary of the invention

Object of the present invention provides a kind of new technical scheme of life preserver to tighten life belt, and it can also can provide lifesaving timely to protect while providing freedom of movement for people.

Technical solution of the present invention realizes like this, it comprises hollow and has the ring-type band of telescopic resilience, the outside wall surface of described band is processed with an opening, is pasted with at opening part the valve cap having valve chamber in segment shape, the outside face center fixture of valve cap has button, is covered with stage clip under button; Be distributed with several pore at the bottom of the valve of valve cap, pore is coated with film, be simultaneously placed with sodium peroxide valve chamber is built-in.

The invention has the beneficial effects as follows can provide for people prevent drowning prevention safety ensure while reduce as much as possible people in water activity restriction.

accompanying drawing illustrates:

Fig. 1 is the semisectional view that the design illustrates.

In each figure, 1 is band, and 2 is valve cap, and 3 is button, and 4 is spring, and 5 is pore, and 6 is film, and 7 is valve chamber, and 8 is sodium peroxide, and 9 is opening.

detailed description of the invention:

Casehistory the design is carried out below in conjunction with accompanying drawing.

As shown in Figure 1, band 1 is a hollow and has the ring-type band of telescopic resilience, and the available more ageing-resistant and good butyl rubber melting of elasticity processes, and haply as the inner tube of a tyre of tire, just carcass is thicker in increase air-tightness and safety, band outside wall surface is processed with an opening 9, opening is pasted with in segment shape the valve cap 2 having cavity (i.e. valve chamber 7), paste position at the bottom of the box of valve cap on, there is button 3 at the end face center of valve cap by circular boring device, as shown in the figure, button is covered with one end of spring 4 for 3 times, the other end of spring then stretching at the bottom of box on, this perforate clogging of this stretching of nationality acting button meeting leak tightness, when touching the button under having external force, this leak tightness just can be broken, also be distributed with several pore 5 at the bottom of the box of valve cap, the more weak film of pressure 6 is born in being coated with that pore seals, simultaneously at the built-in sodium peroxide 8 being placed with constant weight of valve chamber, so, the design tighten life belt and casehistory is complete, the concrete model will selecting to be applicable to when using under such as people before water by its collar in oxter, valve cap position is preferably forward so that operation, because it has certain elasticity can tighten in body surface, little to Activity Effects in the water of people, the danger of feeling drowned as people then presses button 3 temporarily, water just can enter valve chamber 7 and produce a large amount of oxygen with sodium peroxide generation chemical reaction, the calculating of outline can be expanded hundreds of times relative to the volume of its moment of volume of powdery sodium peroxide, high-pressure gas in the valve chamber film 6 that can break through on the pore 5 at the bottom of valve cap box to enter in band and is heaved and is expanded to certain rugosity, thus generation lifesaving buoyancy gives people to help lifesaving, just can produce the buoyancy of tens of kilograms after reacting with water at about 200 grams according to the weight of the sodium peroxide calculated in valve chamber, respond well.

Claims

1. tighten life belt for one kind, it comprises hollow and has the ring-type band of telescopic resilience, it is characterized in that in the outside wall surface of described band, be processed with an opening, is pasted with at opening part the valve cap having valve chamber in segment shape, the outside face center fixture of valve cap has button, is covered with stage clip under button; Be distributed with several pore at the bottom of the valve of valve cap, pore is coated with film, be simultaneously placed with sodium peroxide valve chamber is built-in.
