[0018] Advantages of the present invention:

[0019] 1. When the door of the present invention is opened, the first ratchet heads provided at the ends of the shaft rods at both ends of the first adapter seat interact with the second ratchet head, so that the second ratchet head compresses the door closing spring and the buffer oil. After releasing the acting force for opening the door, the door closing spring and the buffer oil drive the rotation and reset between the first adapter seat and the second adapter seat, realizing the automatic door closing of the door leaf. And by rotating the pressure regulating bolt, the elastic force of the door closing spring and the oil pressure of the buffer oil are adjusted, so that the automatic closing speed of the door leaf can be changed, and the sequence of closing the two door leaves can be adjusted.

[0020] 2. By pressing the lock cover of the present invention, the second wedge block interacts with the first wedge block on the lock rod, so as to realize the traction of the lock rod. Under the traction of the lock head pull rod, the lock head bolt is disengaged from the lock hole for inserting the lock head bolt on the cross beam sheet metal, so that the opening of the door leaf can be realized, making the opening and closing of the door leaf more rapid and convenient. At the same time, two lock head assemblies are provided to lock with the door frame, greatly improving the impact resistance and anti-deformation performance of the door leaf.

[0021] 3. After the door leaf is closed, the strengthening pin abuts against the strengthening sheet metal provided behind the door leaf to improve the structural connection at the door closing edge position of the two doors. At the same time, after the door leaf is closed, the convex block in the first automatic bolt seat is retracted into the first automatic bolt seat under the abutment, and the lever head is pulled through the traction block, so that the lever head pushes the automatic bolt slide seat inside the second automatic bolt seat upward, so that the automatic bolt at the upper end of the automatic bolt slide seat is inserted and matched with the bolt hole opened on the cross beam sheet metal, strengthening the impact resistance and anti-deformation performance of the door leaf. And when the door leaf is opened, the automatic bolt slide seat is reset under the action of the automatic bolt return spring, and the automatic bolt is disengaged from the bolt hole, so that it can be automatically opened when the door leaf is opened.

[0022] 4. By means of the angle encoder provided on the hinge and the door closing inductor for detecting the locking state of the lock head assembly of the present invention, it is judged whether the door leaf is in a fully closed state, otherwise a warning signal can be output, replacing the traditional door magnetic.

[0023] 5. The processor module determines whether there is an emergency disaster situation based on the temperature and humidity data collected by the temperature and humidity sensor. After a disaster situation is detected, the processor module issues an instruction to the electronic control module to control the electromagnet to work, so that the magnetized end of the electromagnet attracts the armature provided at the end of the lock rod, realizing the traction of the lock rod, that is, realizing the function of automatically opening the lock.

[0024] 6. In the present invention, the fireproof filling block adopts a self-developed inorganic material fireproof door core board composed of waste materials such as low-temperature foamed ceramics and cement. Its main material components are fly ash, coal gangue, slag, expanded vermiculite, and ceramics, which form a board through inorganic foaming. It not only has excellent fireproof performance, moisture-proof performance, and a more solid structure, but also has excellent sound insulation performance.

[0025] 7. The door closer hinge in the present invention can not only close the door but also has a positioning function, replacing the traditional door closer, door stopper, and door stop. According to the fire prevention requirements, it ensures the normally open and normally closed states of the fire door. BRIEF DESCRIPTION OF THE DRAWINGS
