The invention discloses an
inertia driving rotor isolation mechanism, and belongs to the technical field of fuse safety mechanism. The isolation mechanism comprises a main body provided with a rotor hole, and a rotor embedded in the rotor hole; the rotor and the main body are provided with holes for accommodating such parts as a manual pin pusher, an
inert safety part, a lock pin, a conversion switch, a fire transfer part and an explosion propagation part; and through preferential structural parts and preferential hole positions, even if the isolation mechanism has a larger isolation relief
turning angle, the state of the isolation mechanism can be precisely identified and returned, and the isolation mechanism can be locked in the state in each state. Through settings, on the one hand, the safety of the mechanism in the safety state is guaranteed, the alignment of
detonation sequences in an arming state is guaranteed, and the
detonation efficiency is greatly improved; and on the other hand, such parts as the conversion switch is applied to effectively identify the state of the isolation mechanism to return to the
control system, so that the safety and the
detonation efficiency of the isolation mechanism can be further improved.
