Provided is an armored lock. A linkage fork and a push-pull pillar are arranged inside a lock shell, wherein the linkage fork can pull a main inserting tongue assembly to stretch out of or retract into a side plate under the action of a middle shifting fork, and the push-pull pillar is arranged on the main inserting tongue assembly, can act on a sky bolt and a ground bolt and enables the front end of the sky bolt and the front end of the ground bolt to simultaneously slide into or out of the lock shell. A safety pin linkage transmission block, a primary linkage arm and a secondary linkage arm are further arranged inside the lock shell, a safety pin is opened through the linkage fork, the push-pull pillar, the safety pin linkage transmission block, the primary linkage arm and the secondary linkage arm under the action of the middle shifting fork, and a door is locked and unlocked by opening an inner lever handle of the armored lock in a room accordingly. Therefore, the armored lock is reasonable in structure, the door is unlocked and locked by operating the inner lever handle quite conveniently, the situation that a user is in a muddle when looking for a key anywhere and manually rotating a safety shifting fork in order to unlock the door under emergency conditions can be avoided, and the escape efficiency under the emergency conditions can be improved.
