Abstract

The invention provides a lifesaving gun for drowning people. The lifesaving gun comprises a trigger, a gun body, a spring compression disc, a bullet, an impact spring and a gunsight. The structure of the lifesaving gun is characterized in that a handle of the gun body is provided with the trigger, the trigger is connected with the spring compression disc arranged at the central part of the gun body, one end of the impact spring is connected with the spring compression disc, the other end of the impact spring abuts with the bullet, and the gunsight is connected with the front end of the gun body. The bullet is composed of a bullet body and an elastic lifebuoy; and the bullet body is composed of a bullet head, a foaming medicine bag, a gas-guide tube, a minisized motor, a crank connecting rod, a time delay relay, a sealed pipe and an impact switch. The lifesaving gun provided by the invention is small-sized emergency drowning lifesaving equipment which has the advantages of a compact light structure, convenience in use, usage of an electromagnetic time-delay function, adoption of chemical foaming, a fast reaction speed, accurate launching of the lifesaving bullet to drowning people, fast inflation of the lifebuoy and great popularization and application values.

Description

Life gun falls into water

Technical field

The present invention relates to a kind of drowning life gun.

Background technology

Aquatic sports is the favorite sports eventss of people in summer, it comprises swimming, dive under water and row the boat etc., because aquatics programme has danger, general people can take necessary anti-drowned measure, buoy quoit for example, equipment such as life jacket, but these measure limitation are very big, this death toll that has also just brought up aquatic sports every year is higher than the reason of traffic accident far away, the reason that general natatory people drowns is mostly because physiologic factors such as cramps, not natatory people then is the slow in reacting or factor of safeguard procedures own, therefore shortage and the single of protective articles of present aquatic sports safeguard procedures make this motion still have very high danger, present protective articles is very passive in use, it is also very blunt to react, trouble is used in operation, can't in time save the drowning person, the device that the similar formula lifesaving of jettisoninging also occurred at present, for example the patent No. is 200420024242.6 disclosed a kind of Lifesaving Heaving Devices, this class device has the fireballing advantage of lifesaving, but present design is science not very, adopt gas cylinder, machine designs such as compression indicator, be very easy to make mistakes, volume is also very big, can not generally promote the use of.

Summary of the invention

The object of the present invention is to provide a kind of drowning life gun, it is light and handy that it has structure, the easy to use and fast advantage of lifesaving speed of response.

The present invention is achieved like this, it comprises trigger, rifle body, spring compact disk, bullet, bump spring and vane of instrument, the handle that it is characterized in that the rifle body is provided with trigger, trigger links to each other with the spring compact disk at rifle body middle part, one end of bump spring is connected on the spring compact disk, other end next-door neighbour bullet, rifle body front end is connected with vane of instrument; Described bullet is to be made of body and elasticity buoy quoit, body is by bullet, the foaming cartridge bag, the ventilation flue, miniature motor, crank connecting link, slug relay, sealed tube and impact switch constitute, the elasticity buoy quoit is connected the periphery of body, the upper end of impact switch links to each other with slug relay in the sealed tube, be provided with two foaming cartridge bags in the bullet of sealed tube upper end, ventilation flue's upper end links to each other with bullet, ventilation flue's lower end links to each other with the elasticity buoy quoit, slug relay also links to each other with miniature motor in the sealed tube, crank connecting link is between foaming cartridge bag and miniature motor, and the lower end of crank connecting link links to each other with the output shaft of miniature motor; Described two foaming cartridge bags are the chemical that produces gas after two mixing, for example dilute hydrochloric acid solution and powdered sodium carbonate etc.

Technique effect of the present invention is: the present invention is advantages of compact and light structure not only, use also very convenient, adopt the electromagnetism delay function, chemical blowing, speed of response is fast, accurately launch the lifesaving bullet by life gun to the drowning person, the buoy quoit inflation is fast, is to have very much the small-sized emergent drowned life that promotion and application are worth.

Trigger 2, rifle body 3, spring compact disk 4, bullet 5, bump spring 6, vane of instrument 7, bullet 8, foaming cartridge bag 9, ventilation flue 10, miniature motor 11, crank connecting link 12, slug relay 13, sealed tube 14, impact switch 15, elasticity buoy quoit in the drawings, 1.

The specific embodiment

As shown in Figure 1, the present invention is achieved like this, it comprises trigger 1, rifle body 2, spring compact disk 3, bullet 4, bump spring 5 and vane of instrument 6, its constructional feature is that the handle of rifle body 2 is provided with trigger 1, trigger 1 links to each other with the spring compact disk 3 at rifle body 2 middle parts, one end of bump spring 5 is connected on the spring compact disk 3, other end next-door neighbour bullet 4, and rifle body 2 front ends are connected with vane of instrument 6; Described bullet is to be made of body and elasticity buoy quoit 15, and as shown in Figure 3, body is to be made of bullet 7, foaming cartridge bag 8, ventilation flue 9, miniature motor 10, crank connecting link 11, slug relay 12, sealed tube 13 and impact switch 14, as shown in Figure 2; Elasticity buoy quoit 15 is connected the periphery of body, slug relay 12 in the upper end of impact switch 14 and the sealed tube 13 links to each other, be provided with two foaming cartridge bags 8 in the bullet 7 of sealed tube 13 upper ends, ventilation flue 9 upper end links to each other with bullet 7, ventilation flue 9 lower end links to each other with elasticity buoy quoit 15, slug relay 12 also links to each other with miniature motor 10 in the sealed tube 13, and crank connecting link 11 is foaming between cartridge bag 8 and the miniature motor 10, and the lower end of crank connecting link 11 links to each other with the output shaft of miniature motor 10; Described two foaming cartridge bags 8 are the chemical that produces gas after two mixing, for example dilute hydrochloric acid solution and powdered sodium carbonate etc.

Operating process of the present invention is such, when lifesaving, after the user uses vane of instrument 6 aiming drowning persons, cocking 1, spring compact disk feasible bump of 3 moments spring 5 recovers deformation, bump spring 5 bump bullets 4, bullet 4 flies near the drowning person, bullet 4 is after being clashed into, and impact switch 14 starts slug relay 12, and slug relay's 12 delays just can start miniature motor 10 in 2-5 seconds, after miniature motor 10 rotates, crank connecting link 11 will upward movement, breaks chemical in 8, two foaming cartridge bags of two foaming cartridge bags 8 and mixes the back and produce a large amount of gases, gas is inflated to elasticity buoy quoit 15 by ventilation flue 9, as shown in Figure 4, make bullet 4 keep very little profile flight 2-5 seconds like this, prolonged flying distance, and can repeat to load bullet 4, improved the range of use of throwing type life so greatly, speed of response is very fast, and control is convenient.
