The invention discloses an armored door leaf structure. The armored door leaf structure consists of a door core, a decorative outer door plate, an outer door plate decorative covered edge, a screw A, a door leaf sealing strip, a decorative inner door plate, a screw B and an inner door plate covered edge. A whole covered edge of a door leaf is divided into a split structure of the outer door plate decorative covered edge and the inner door plate covered edge, therefore, the problem of 45-degree chamfer angles of four corners of inner and outer door plates of the door leaf is solved. External covered edge fixing screws are all designed to be in a built-in fixing screw mode so as to improve the attractiveness of the side edge of the door leaf. A clamping groove A, a clamping groove B and a C-shaped clamping groove C are designed on the outer door plate decorative covered edge, the clamping groove B is clamped with the side edge of the decorative outer door plate, the clamping groove A and a door core outer extending lug edge are in clamped connected and fixed through the screw A, the door leaf sealing strip is clamped in the C-shaped clamping groove C of the outer door plate decorative covered edge, prying resistance and airtightness of t-shaped cover edge of the door leaf are greatly enhanced, and the door leaf is not prone to being pried. The inner door plate covered edge is arranged on the periphery of the decorative inner door plate, a clamping groove and an abutting head are arranged on the inner door plate covered edge, the clamping groove is connected to the side edge of the decorative inner door plate in a clamped mode, and the abutting head abuts against the bent outer corner A of the side edge of a profile of a door core frame; and the decorative inner door plate and the inner door plate covered edge are fixed to the door core frame by the screw B from the inner side of the profile on the periphery of the door core frame to the outer side, and thus a double-step door leaf structure is formed.

The invention discloses a method capable of automatically counter locking an anti-theft door control lock catch. The method comprises the steps that an end plate is installed on a door, so that an electronic lock corresponds to the position where a positioning buckle is arranged; and prestored radio frequency card information and open mode passwords are controlled, a radio frequency card is placed on a card reader, the card reader reads the radio frequency card, a signal of the card reader is received by a controller and compared with the stored information, and when the signal of the card reader is matched with the stored information, the card reader information is sent into a displayer by the controller to be displayed. According to the method capable of automatically counter locking the anti-theft door control lock catch, the lock catch is matched with the positioning buckle, and the door can be locked; and due to the fact that the counter lock catch structure is arranged, when an electromagnet is not powered on, the counter lock catch is inclined towards the outer side under the action of the elastic force of a reset spring and can be clamped on the positioning buckle through the action of a limiting part, the door is counter locked, operation is easy, and the safety performance is high.

The invention provides a steel entry door leaf with a good door lock prying-resistant performance.
