The invention provides an integrated car door lock synchronous door knife, and belongs to the technical field of elevators. Comprising a door knife bottom plate, a door knife mechanism, a positioning plate, a lock hook swing arm and a ram support are installed on the door knife bottom plate, the ram support is used for opening or closing the positioning plate, the positioning plate is used for limiting swing of the lock hook swing arm, and the lock hook swing arm is used for driving the door knife mechanism to retract or expand. Double-blade unlocking is adopted, when the door is close to the door closing state, a rubber ram installed on a ram support opens a positioning plate, at the moment, an elevator operates normally, and when the door is closed, the positioning plate locks a lock hook swing arm under the action of gravity and a second spring, so that false operation of the door blade in the operation process is prevented, safety is high, and safety is high. The emergency unlocking steel wire rope is installed on the door knife, when an emergency situation occurs due to the fact that the elevator cannot run due to power failure of the elevator or other reasons, rescue workers pull the emergency unlocking steel wire rope to enable the lock hook to be lifted up, then the car door plate can be opened, and rescue difficulty is reduced.
