Automatic-alarming push-down type emergency door-locking device

An automatic-alarming push-down type emergency door-locking device, disposed at a door board, the door board including a locking side neighboring to at least one locking groove, comprising:

• a main lock seat, disposed by neighboring to the locking side of the door board, having at least one locking element;
• a secondary lock seat, disposed by being away from the locking side than the main lock seat;
• a push-down type handle assembly, including:
• a first handle, connected pivotally with the secondary lock seat, configured for being controlled to move pivotally toward an unlocking position along a driving path from a locking position;
• a second handle, connected pivotally with the main lock seat, configured for being controlled to move with the first handle along the driving path;
• wherein, while at the locking position, the at least one locking element is buckled with the at least one locking groove;
• wherein, while at the unlocking position, the at least one locking element is separated from the at least one locking groove;
• and
• a push-down horizontal bar, bridging the first handle and the second handle so as to have the second handle and the first handle to be connected in a coherent manner;
• a position-sensing module, disposed at the secondary lock seat, configured for sensing whether or not the first handle has been separated from the locking position, and transmitting an alarm-triggering signal if positive;
• and
• an alarm module, connected electrically with the position-sensing module inside the secondary lock seat, configured for issuing an alarm upon when the alarm-triggering signal is received in a function-on state.
