Pneumatic throwing device

Abstract

The invention discloses a pneumatic throwing device consisting of a lifesaving device, a miniature gas storage bottle and a throwing transmitter. The lifesaving device provided with an automatic inflating device and a first CO2 gas bottle are wrapped by folding in a lifesaving shell and arranged in a transmitting tube; the miniature gas storage bottle is connected to an air chamber sleeve and comprises a gas bottle connecting seat, a grip handle, a second CO2 gas bottle, a striker and the like and forms release gas entering a gas storage chamber; a throwing transmitter comprises a gas chamber sleeve, a connecting seat, a transmitting trigger, a connecting rod, a transmitting valve rod, a return spring, a safety pin and the like; and the has chamber sleeve is connected with the transmitting tube. When the pneumatic throwing device is in use, a throwing rope is connected with a connecting rope of a lifesaving shell, the throwing device is gripped to aim at the front part of a target, the gas bottle is penetrated through the striker by rotating the grip handle, the gas in the gas bottle is instantly released to fully fill the gas storage chamber, then the transmitting trigger is triggered, a gas outlet is opened and the rescue is implemented by throwing the lifesaving device to a rescued target under the pneumatic pressure. The throwing device has the advantages of light weight, small size, convenient carrying, safe and reliable use, long throwing distance and high lifesaving efficiency.

Description

technical field [0001] The invention relates to a lifesaving device, in particular to a pneumatic thrower. Background technique [0002] For personnel engaged in water surveys, water sports, water rescue, tourism, fishermen fishing, etc., in order to ensure personal safety, they must directly wear emergency life jackets for timely self-rescue and rescue. The life-saving equipment of prior art, mostly with self-rescue, some also can be used for rescue of course, not only can be used for self-rescue but also can be used for throwing rescue by others like buoy buoy, life-saving ring and so on, but because throwing distance is inaccurate or If the target is too far away, it is often difficult for the rescued to grasp the life-saving appliance, and the life-saving efficiency is low. Therefore, it is urgent to provide a pneumatic thrower with a long throwing distance and high life-saving efficiency. Contents of the invention [0003] The object of the present invention is to ov...
