Fireproof door capable of being locked 2 minutes after door opening and closing
The invention discloses a fireproof door capable of being locked 2 minutes after door opening and closing. A photoelectric switch which is used for inducting the door opening action is arranged on a door frame. A door lock is in transmitting connection with a drive motor installed in a door body through a drive shaft. A control circuit comprises a power module, a main control module, a starting switch and a retarder, wherein the main control module is electrically connected with the retarder and the photoelectric switch bi-directionally, the main control module output is electrically connected with the starting switch, the starting switch is electrically connected with the drive motor, and the power module output is electrically connected with the main control module, the starting switch, the retarder and the photoelectric switch. Due to the fact that the control circuit which can delay the locking time controls the drive motor to drive a lock cylinder of the door lock and realizes the automatic opening and closing of a lock body, the automatic locking 2 minutes after the fireproof door is closed can be realized, the situation that fire spreading when fire disaster happens due to the miss locking of the fireproof door can be avoided, and the fireproofing grade of the fireproof door can be improved.
