Abstract

The utility model relates to a self life saving device for swimming and comprises a gas filling belt, a shoulder back belt, a connecting guide pipe and a gas source box. The self life saving device for swimming is flat, light, handy and soft in the ordinary time and doesn't affect the normal swimming and the working on water. When the emergency situation happens, a swimmer only needs to manually trigger and the automatic gas filling is at once carried out to increase the floating force. The self life saving device for swimming has the advantages of reasonable design, easy fabrication, beautiful appearance and low cost and is very suitable.

Description

Self-lifesaving appliance for swimming

A kind of self-saving swimming is given birth to device, belongs to the essential a kind of life of human lives.

Existing swimming lifesaving circle, be to make open circle with the rubber inner tube of a tyre or plastics, with the Floor Pump gas of manually substituting the bad for the good, this buoy quoit can not very fast association be swum owing to can not leave support for the beginning swimmer, and natatory people generally is unwilling to be with it, meet the twin or Other dangers situation of leg convulsion as swimmer's halfway, then do not have the lifesaving apparatus at one's side, cause the accident, summer in all parts of the country is surprising because of the swimming death toll, crewman who works on the water in addition or steamer passenger, the life jacket that has is two sponge blocks of front and back chest, and the outside is seamed into the vest shape with cloth, bulky, stiff, put on it and be inconvenient to work.

The purpose of this utility model, flat, soft in the time of will developing a kind of light, small and exquisite, when swimming or aquatic work exactly, and under precarious position, the effortlessly automatic gas filed self-saving swimming of swimmer self is given birth to device.

This self-saving swimming is given birth to device, as shown in drawings, by aeration zone (1), shoulder harness (2), source of the gas box (3), connecting duct (4) is formed, aeration zone (1) is hollow inner bag of latex and colored nylon silk fabric overcoat, toggle knot (5) by self can connect into annular, two ports valves are installed on the aeration zone (1), one for manually inflating ports valve, another is connecting connecting duct (4), connecting duct (4) other end then connects source of the gas box (3), shoulder harness (2) two ends are fixed on the aeration zone (1), source of the gas box (3) inner structure is as follows: have source of the gas bottle (6), copper sheet (7), copper sheet seat (8), striker cap (9), striker (10), percussion spring (11), collision block (12), spring perch (13), trigger (14), Trigger safety (15), source of the gas bottle (6) is high voltage bearing heavy wall bottle, interior dress high-pressure liquid nitrogen or liquid carbon dioxide or other liquefied gas, copper sheet seat (8) centre hole penetrates, one end is connected by male thread with striker cap (9), the other end and source of the gas bottle (6) are by interior screwed connection, but with the middle copper sheet (7) that is placed with in source of the gas bottle (6) junction, striker cap (9) garden, center borehole jack dress striker (10), striker cap (9) one sides have air gate and communicate with hole, garden, center, air gate and connecting duct (4) join, connecting duct (4) other end connects aeration zone (1), percussion spring (11) is installed in the spring perch (13), one end is fixed on spring perch (13) inwall, percussion spring (11) other end end is fixed with collision block (12), manually collision block (12) compression percussion spring (11) is until being fastened by trigger (14), trigger (14) is fixed on the spring perch (13), and trigger (14) is covered with Trigger safety (15).

Do not use this self-saving swimming to give birth to device; by the unlikely action of Trigger safety (15) protection trigger; the swimmer opens Trigger safety (15) before the following water; when normal swimming; the swimmer puts on does not have gas filed self-saving swimming to give birth to device; flat; lightly; do not influence normal swimming or work, but when meeting emergency situation, manually operated trigger (14); percussion spring (11) flicks rapidly; drive collision block (12) bump striker (10), striker (10) punctures copper sheet (7), the blue gas in the source of the gas bottle (6) rapidly in the bottle through copper sheet seat (8); striker cap (9); connecting duct (4) enters aeration zone (1) inflation; make the people increase buoyancy, reach the purpose of first aid.

As without source of the gas box (3), give and accomplish fluently gas earlier with manually inflating ports valve, then can make common used for life buoy.

It is such that source of the gas bottle (6) replenishes blue gas: as long as unscrew copper sheet seat (8), then external blue gas from all around gap of copper sheet seat (8) centre hole, copper sheet (7), enter the source of the gas bottleneck, after replenishing blue gas, tighten copper sheet seat (8), drive copper sheet (7), compress the source of the gas bottleneck, reach sealing purpose.

Fig. 1 is the utility model accompanying drawing.

The accompanying drawing marking explanation:

1---aeration zone

2---shoulder harness

3---the source of the gas box

4---connecting duct

5---the toggle knot

6---the source of the gas bottle

7---copper sheet

8---the copper sheet seat

9---the striker cap

10---striker

11---the percussion spring

12---collision block

13---spring perch

14---trigger

15---Trigger safety

Make this self-saving swimming and give birth to device, the aeration zone overcoat can adopt colored nylon silk fabric material, inner bag is thin latex of moulding or thin rubber, inflation box shell is that plastics are made, and source of the gas bottle and copper sheet seat are that nylon 1010 or steel, copper material machinework are made, and striker is with No. 10 steel, connecting duct and joint all can adopt nylon 1010, shoulder harness is a nylon tape, and other are gauge member, and market is bought.

This kind swimming is used light from brucker survival capsule at ordinary times, do not affect normal swimming or work, meet emergency, can automatically inflate, reasonable in design, volume is little, easy to manufacture, in addition part mostly adopts standard component, and is aesthetic in appearance, cost is low, for trip swimmer or worker waterborne, passenger preferably from the lifesaving instrument.
