The invention provides an ignition mechanism for long-distance safe ignition of a solid rocket motor, which is used for the remote ignition of the solid rocket motor to prevent misfire of the rocket motor during storage, transportation and operation. The technical features are: the hollow cup motor with stable performance is used as the power source, the secondary reducer is decelerated, the limit position is accurately designed on the base, and the rotation of the rotating cross is driven by the motor acceleration and decelerator, and the functions of isolation and explosion are realized at different positions. , The uniquely designed contact switch accurately realizes the status indication. It has been verified by tests that the safety ignition mechanism has reliable performance, stable quality, easy assembly, and can be used for long-distance ignition of solid rocket motors.
