The invention relates to an elevator with a gravity type self-locking safety device. In an existing elevator, opening of an elevator door is controlled usually by an electrical system, and unpredictable factors like unstable programs and virus attack exist. The elevator with the gravity type self-locking safety device is characterized by comprising a guide frame and the gravity type self-locking safety device; the guide frame moves vertically along with an elevator car; the gravity type self-locking safety device enables an interlayer door to be in a locking state when the elevator car vertically moves to leave the butt joint position with the interlayer door and unlocks the interlayer door when the elevator car and the interlayer door are in complete butt joint; the gravity type self-locking safety device comprises a drive body controlled by the guide frame to move front and back, a locking block for preventing the interlayer door from being opened when in the lowest position under the dead load action, a linkage piece driving the locking block to vertically move through front-and-back movement of the drive body, a machine frame, and an unlocking handle for moving the locking block to the highest position to unlock the interlayer door in a manual mode when the elevator car and the interlayer door are not in complete butt joint. The elevator with the gravity type self-locking safety device is safe and reliable.
