Problems solved by technology

The disadvantage of this type of trigger is that the force required to puncture the cylinder is high and the water soluble fiber thread must withstand this force
If the water-soluble fiber thread body is subjected to such a large force for a long time, the water-soluble fiber thread body is easily broken, thereby causing a malfunction of the trigger device an

Abstract

The invention provides a triggering mechanism of a life-saving device, comprising a shell, a driving assembly and a traction rope. The driving assembly comprises a handspike, a rotary rod, a thimble and a hook rod, wherein the rotary rod, the thimble and handspike are distributed in the shell in an n shape, one end of the thimble abuts on an air bottle, the other end of the thimble abuts on the side surface of the rotary rod, one end of the handspike is provided with a main spring, one end of the handspike abuts on one end of the main spring, the other end of the handspike abuts on the side surface of the rotary rod, the hook rod is arranged in the shell, a gemel is arranged at the long-edge end of the hook rod and provided with a booster spring at the outer side, the booster spring is parallel to the gemel, and one end of the traction rope is fixedly connected with a middle rotating shaft of the gemel. During the inflation, the rotary rod rotates by using the supporting shaft as a fulcrum to abut on the thimble, the thimble pierces the air bottle under the action of the rotary rod, and the air is released, thus the inflation of the life-saving device is completed so as to activate great power with smaller force.

Description

technical field [0001] The invention relates to a trigger mechanism, in particular to a trigger mechanism of a lifesaving device, belonging to the technical field of water lifesaving equipment. Background technique [0002] At present, there is a kind of water lifesaving equipment called projective lifesaving equipment. Its working principle is to use a power device or manpower to project an inflatable lifebuoy into the water near the person who fell into the water, and then realize the inflation of the lifebuoy through the trigger mechanism, and provide buoyancy for the person who fell into the water. [0003] The traditional trigger mechanism includes a shell, which has a ventilating chamber, and a ventilating screw hole and an venting screw hole are formed on the outside of the ventilating chamber to respectively connect the inflatable steel cylinder and the life-saving air bag, and on the other side there is a ventilating chamber. The driving rod with forward and backwar...
