The invention relates to the technical field of elevators, in particular to an elevator door lock. The door lock body comprises a spring bolt fixing plate arranged in a lintel, a spring bolt guide sleeve fixed to the spring bolt fixing plate, a spring bolt vertically connected to the spring bolt guide sleeve in a sliding mode, a spring bolt spring used for driving the spring bolt to reset, and a driving spring bolt (6) arranged on the spring bolt fixing plate and used for driving the spring bolt (6) to reset. The driving mechanism moves vertically, the sensor is arranged on the spring bolt fixing plate and used for detecting the state of the door lock, a lock catch hole is formed in the door body, the spring bolt extends into the lock catch hole to lock the door body, the spring bolt is further provided with a mechanical triggering mechanism used for detecting the state of the door lock, and when the door lock is in a locked state, the mechanical triggering mechanism is used for triggering the mechanical triggering mechanism. The sensor detects that the door lock is in a locked state, and meanwhile the mechanical triggering mechanism is triggered. The elevator door lock is convenient to install and small in potential safety hazard.
