The invention relates to the technical field of locks, in particular to an integrated electromagnetic lock of a subway safety door. A lock cam and an electromagnetic cam are connected with each other by using a cam connecting shaft; a locking device is arranged at the bottom of the electromagnetic cam; the electromagnetic cam is placed in a lock body; a manual unlocking pin is arranged on the lock body and placed at the upper end of the lock body; the manual unlocking pin and the electromagnetic cam are connected with an electromagnetic module in a contacting way; a lock pin is arranged on the electromagnetic module and connected with the electromagnetic cam in a contacting way; an upper lockup detecting jogging and a lower lockup detecting jogging are respectively placed at the upper end and the lower end of a quick-action switch bracket; the upper lockup detecting jogging is connected with the electromagnetic module; the lower lockup detecting jogging is connected with the electromagnetic module; and a manual unlocking detecting jogging is arranged at the upper end of the electromagnetic module and positioned at the connection of the upper lockup detecting jogging and the electromagnetic module. The integrated electromagnetic lock has the advantages as follows as follows: through the adoption of a structure of a micro-stroke electromagnetic lock pin and the electromagnetic cam, the volume of an executing lock is greatly reduced, the lock structure is completely packaged in the lock body and a neat and beautiful appearance is obtained.
Description
technical field [0001] The invention relates to an electromagnetic lock, in particular to an integrated electromagnetic lock for a subway safety door. Background technique [0002] With the wide application of safety doors on platforms and platforms, more and more attention has been paid to the safety of passengers. Among the safety doors with sliding doors of push-pull structure, this is the only type of passage for passengers to enter and exit the train. Therefore, the locked state It is very important to reliably lock and open the lower sliding door; the safety door lock device currently used has a complicated structure and high cost. [0003] The subway safety door electromagnetic lock is an electric control lock used in the subway safety door system. Subway safety doors are gradually emerging in rail transit. They improve the riding environment of train platforms and ensure the safety of passengers. The core part of the safety door is the sliding door body that is syn...
