Abstract

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.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door that is automatically locked after 2 minutes of opening and closing. Background technique [0002] The current locking methods for fire doors are all manually operated. In our use, every time we close the door, we need to manually insert the key into the lock hole and rotate it to achieve the locking effect. It is very troublesome and easy. Occur the situation of leaking lock, if break out fire intensity of fire is easy to spread, has brought very big potential safety hazard to the user. Contents of the invention [0003] The object of the present invention is to provide a fire door that locks automatically after 2 minutes of opening and closing, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a fire door that locks au...
