Quick opening mechanism for gas-production pull pin

The invention provides a quick opening mechanism for a gas-production pull pin. The quick opening mechanism is characterized by structurally comprising a diaphragm base, a pressure diaphragm, a piston barrel, a blunderbuss head, a spring, a pin, a safety jacking wire, a trigger cavity, a reagent cavity, a leading wire post and a gas exhaust choke plug, wherein the diaphragm is arranged inside a diaphragm base positioning slot; the blunderbuss head and the spring are arranged inside the piston barrel; the spring is connected with the piston barrel through threads; the diaphragm base and the piston barrel are connected through a bolt; the trigger cavity is connected with the piston barrel through threads; and a pin of the trigger cavity is connected with a blocking key slot of the blunderbuss head inside the piston barrel. The quick opening mechanism provided by the invention adopts an opening mode of instantly generating gas by adopting a gas-production reagent, pushing the pin and breaking down the diaphragm through accumulated energy of the spring; and the manufactured quick opening mechanism for the gas-production pull pin can break down a sealing diaphragm within 20 milliseconds, effectively realizes quick spraying of a fire extinguishing medium of an explosion suppressor, and has the advantages of high safety, good spraying performance and high reaction speed.
