By adopting such a manner, the life saving casting device is compact in size, light in weight, as a result carrying by rescue worker to an appropriate location in emergency field for ejection is facilitated, which is beneficial to holding best life-saving opportunity by the rescue worker, and difficulty of rescuing the trapped is lowered.

Description

Life-saving casting device

Technical field

The present invention relates to the lifesaving apparatus, relate in particular to a kind of life-saving casting device.

Background technology

The accident scene such as fighting flood and relieve victims, flash flood, marine billow, ship are in danger, when trapped personnel is in that clutch need be rescued and rescue group can't be near captive the time, common buoy quoit is difficult to give trapped personnel, even trapped personnel obtains buoy quoit, but harsh environment because of blast, billow, torrent, trapped personnel self is difficult to pull through, and the rescue group just may lose best rescue opportunity, causes trapped personnel to fall into water wrecked or because of cold hungry dying.The Chinese patent publication number is the patent of invention of CN101021398A, disclosed a kind of life-saving casting device; China Patent No. is 200420024242.6 patent of invention, disclosed a kind of Lifesaving Heaving Device, it all can overcome the deficiency of common buoy quoit, improve lifesaving efficient, when the rescue group implements to rescue, buoy quoit can be transmitted into the too late distance of manpower over tens meters, adorn tens meters long lifelines on the buoy quoit, buoy quoit can be inflated in drowning 5 seconds automatically, as long as trapped personnel is caught buoy quoit and lifeline to be forgotten about it safety zone by the rescue group and is rescued.The life-saving casting device of prior art comprises the projector seat, small of the stock hand, buttstrap, sleeve pipe, nozzle, rifle body adapter piece, impulse flask, the lifesaving tube, lifeline, on the projector seat air-pressure gauge is installed, blowdown valve, aie escape valve, the high pressure connection pipe, small of the stock hand and safety pin, rear portion and launcher shell that buttstrap is positioned at the projector seat form one, has the core hole that o-ring groove and high pressure gas pass through on the rifle body adapter piece, seal ring places in the o-ring groove, when needs are launched once more, just need inflate to impulse flask, usually because rifle body adapter piece does not have seal ring and causes seal failure, the delay inflation, reason is that the seal ring of rifle body adapter piece breaks away from the rifle body when emission, and the rescue group left behind the seal ring of upper cutting gun adapter piece again before rushing towards the accident scene.The structure of the life-saving casting device of prior art, weight is heavier, and volume is bigger, being not easy to the rescue group carries, and often environment is abominable at the accident scene, launches when the rescue group can not take life-saving casting device to suitable position, has just increased the rescue difficulty of trapped personnel.

Summary of the invention

Technical matters to be solved by this invention provides a kind of life-saving casting device, this kind life-saving casting device can make things convenient for the rescue group to launch at the on-the-spot unmarried correct position that is carried into of accident, catch best rescue opportunity thereby help the rescue group, can reduce the difficulty that trapped personnel is rescued.

Solve the problems of the technologies described above, technical scheme of the present invention is: a kind of life-saving casting device, comprise the projector seat, small of the stock hand, buttstrap, sleeve pipe, nozzle, rifle body adapter piece, impulse flask, lifesaving tube and lifeline, described lifeline is positioned in the lower cavity of textiles knapsack of setting, the top of this textiles knapsack has the projector of containing seat, the fastener of small of the stock hand position and sleeve pipe, be provided with detouchable buttstrap Connection Block between the tail end of described projector seat and the buttstrap, described buttstrap Connection Block is a U-shaped, the bearing pin that is provided with in one end of buttstrap and the groove of buttstrap Connection Block is rotationally connected, the axis normal of described bearing pin is in the line of centers of sleeve pipe, and the buttstrap Connection Block is provided with the fixedly locations of buttstrap.

Described textiles knapsack is provided with the waistband that has buckling piece that is fixed in textiles knapsack outside face.

Described rifle body adapter piece is provided with step-like o-ring groove, and described seal ring is embedded in the o-ring groove, and the outer end of described rifle body adapter piece is provided with the interior receipts back-up ring that prevents that seal ring from scurrying out.

Described locations is made up of nut, thread segment and cylindrical section, and described buttstrap is provided with the pin-and-hole that cooperates with the cylindrical section of locations, and described buttstrap Connection Block has the tapped through hole that the thread segment with locations adapts.

Described buttstrap Connection Block and the clamping of projector seat tail end.

Life-saving casting device of the present invention is adopted in such a way, volume is little, in light weight, make the rescue group easy to carry at rescue site, shorten the pitch time of the continuous emission of impulse flask, avoid causing stopping over the normal use of life-saving casting device because of the problem of seal ring, help the rescue group and catch best rescue opportunity, reduced the difficulty that trapped personnel is rescued.
