The invention discloses a synchronous door cam and car door locking device of an elevator. The device comprises a door cam assembly which is mounted on an driving door hanging plate, a secondary lock fixed on a driven door hanging plate, and a triggering body mounting plate which is fixed on a lower bottom plate of a door machine; the door cam assembly comprises a lock hook which is in linkage fitting with the secondary lock and the triggering body mounting plate; the door cam assembly further comprises a bottom plate, a driving connecting rod and a driven connecting rod; the middles of the driving connecting rod and the driven connecting rod are hinged to the bottom plate; a fine moving blade and a movable blade are hinged between the driving connecting rod and the driven connecting rod to form a parallelogram structure; the fine moving blade is connected with the lock hook through a transmission mechanism; the driving connecting rod is connected with a door machine transmission mechanism; the door cam assembly is matched with a door ball on an elevator hall door to trigger the lock hook to act. With the adoption of the device, a car door and the hall door are synchronously opened and closed without adding extra triggering mechanism on the hall door; the mounting and repairing are convenient; the debugging is simple.
