A door locking system (100) for use with a manually operated elevator door: a door frame locking hole (114) is openly provided on a lock mounting surface (112) of an elevator door frame (110); a door locking device (120) comprises a door lock link rod (122) and a lock tongue (124) which is connected to the door lock link rod (122); a door ball device (140) is mounted outside of the elevator door frame (110), the door ball device (140) comprising a door ball link rod (142); an end of a pull cord (130) is connected on the door lock link rod (122), while another end is connected on the door ball link rod (142); a door blade device (150) is mounted on an elevator car; the door blade device (150) presses the door ball link rod (142) when the elevator car reaches a floor, then driving the pull cord (130) to tighten the door lock link rod (122), the door lock link rod (122) driving the lock tongue (124) to retract into the door frame locking hole (114); the door blade device (150) separates from the door ball link rod (142) when the elevator car leaves the floor, and the door ball link rod (142) drives the pull cord (130) to relax the door lock link rod (122), the door lock link rod (122) driving the lock tongue (124) to extend beyond the door frame locking hole (114). The structure of the door locking system (100) for use with a manually operated elevator door is relatively simple and is reliable.
Description
technical field [0001] The invention relates to a door lock system for an elevator hand-pulled door. Background technique [0002] The door lock system of a general hand-pull elevator includes an elevator door frame and a door lock device installed in the elevator door frame. The lock tongue of the A floor can retract the elevator door frame when the elevator car reaches the A floor. At this time, the elevator is manually pulled. door to open the elevator door. When the elevator car leaves the A floor, the elevator door is in a closed state. At this time, the lock tongue of the A floor can extend out of the elevator door frame and be inserted into the lock hole of the elevator door. At this time, the elevator door cannot be opened. [0003] The structure of the door lock system of the general hand-pulled elevator is relatively complex, and the elevator is prone to failure. When the elevator door is in the open state, the latch sticks out of the elevator door frame, so that ...
