The invention belongs to the technical field of elevators, and provides an elevator door knife door lock device which comprises a door knife mechanism, a lock catch mechanism and an emergency unlocking mechanism. The door knife mechanism is arranged on the car door upper sill; the lock catch mechanism comprises a lock plate and a lock bar, the lock plate is installed on the transversely-moving belt, and the lock bar is rotationally connected with the lock plate; the lock plate can drive the tail end of the lock bar to abut against the door knife mechanism in the moving process till the lock bar is tilted and unlocked. The emergency unlocking mechanism comprises a connecting rod; the connecting rod is arranged above the door knife mechanism and the locking bar, and the two ends of the connecting rod can be matched with the door knife mechanism and the lock catch mechanism. The connecting rod and the door knife mechanism are separated, and the connecting rod and the door knife mechanism are not in contact in a normal working state, so that noise caused by collision is avoided, the noise generated in the normal working state is reduced, and the comfort of passengers taking an elevator is greatly improved.
