Abstract

The invention belongs to an aviation lifesaving technology, and relates to a firing mechanism of a power device in a catapult lifesaving system, in particular to a delay firing mechanism utilizing a low overload. The mechanism comprises a cover plate [2], a firing pin [3], a shear pin [4], a stab detonator [5], a firing pin sleeve [6], a diring pin [7], a small steel ball [8], a diring pin spring[9] , a shell [10], a mass block [11], a sleeve [12], a large steel ball [13], a mass block spring [14], a sleeve spring [15] and an installation base [16]. A steel ball lock structure a mass block spring simple harmonic vibration way are adopted, inertia force is increased through low overload input, delay firing of bottom fire or a fire cap with large firing energy is achieved, a mechanical transmission system or a fuel gas transmission system is omitted, and the problems that a seat system is complex in structure and large in mass are solved.

Description

technical field [0001] The invention belongs to aviation lifesaving technology, and relates to a firing mechanism of a power device in a ejection lifesaving system, in particular to a time-delayed firing mechanism utilizing low overload.
