an ignition device

Abstract

The invention discloses a percussion sparking device which comprises a body, a firing pin mechanism, a firing pin locking and unlocking mechanism and a state switch. The state switch comprises contact parts, a switch body, a spring, spring pieces and a bolt. A cavity is formed in the switch body. The bolt is vertically installed in the cavity of the switch body, the lower end of the bolt stretches out of the upper end right facing the firing pin mechanism, the spring sleeves the outer portion of the bolt, and two spring pieces and two groups of contact parts are symmetrically arranged on two sides of the spring. When the firing pin mechanism is located at the locking position, the firing pin mechanism jacks the bolt, the spring pieces are in contact with the two contacts at the upper end of the adjacent contact part, and the state switch is in the communication state. When the firing pin mechanism moves downwards to leave the locking position, the spring pieces and the two contacts at the upper end of the adjacent contact part are not in contact, and the state switch is in the disconnection state. The device has a state remote detection function, improves operation safety and can meet the requirements for use of different initiating explosive devices.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a percussion ignition device. Background technique [0002] At present, many firing mechanisms of domestic pyrotechnic products use acupuncture to fire. In order to ensure the safety of the firing mechanism, a safety pin is generally designed to lock the firing pin. When in use, the safety pin needs to be released manually to release the firing pin. . This design has problems such as low security, difficult remote operation, and difficult state detection. [0003] Zhou Xingming, Deng Kangqing, etc. applied for a utility model patent "Gas Generator Starting Firing Device" (Chinese Patent Application No. 201220682731.5), including the firing pin, firing pin spring, bayonet pin, safety pin, bayonet pull ring connected with the bayonet pin, and starting pull rope , the utility model can realize continuous and rapid axial pulling out of the safety pin and bayonet pin, start the...
