[0032] When the door leaf 2 needs to be locked on the door frame 1, the servo motor 402 is started, and the servo motor 402 drives the first bevel gear 403 to rotate, so that the second bevel gear 404 meshing with the first bevel gear 403 rotates, thereby driving the third bevel gear 405 to rotate, causing the first transmission shaft 406 installed on the third bevel gear 405 to rotate, thereby driving the first lock plate 407 to move toward the door frame 1, and then the first lock tongue 408 installed on the first lock plate 407 moves into the door frame 1, thereby completing the locking of the door frame 1 and the door leaf 2. The anti-theft performance of the security door is improved by the arrangement of several first lock tongues 408, and the personal and property safety of the room is guaranteed; during the operation of the anti-theft mechanism 4, the door closing sensing mechanism 5 is driven to operate synchronously, so as to achieve the effect of automatic door closing when a fire occurs, preventing the flame from spreading to the room and causing personal and property losses.

[0033] Reference Fig. 9 In this embodiment, a T-block 409 is installed on one side wall of the first lock plate 407, and a T-slot 410 is opened on the cavity 3. The T-block 409 is slidably adapted in the T-slot 410, so that the first lock plate 407 can be slidably connected to the cavity 3 through the adaptability of the T-block 409 and the T-slot 410, thereby providing a guide for the moving direction of the first lock plate 407, and avoiding the first lock plate 407 from rotating synchronously with the first transmission shaft 406.

[0034] Reference Figure 6 In this embodiment, a second transmission shaft 411 is connected to the axis of the second bevel gear 404, and a plurality of transmission gears 412 are installed at both ends of the second transmission shaft 411. A rack 413 is meshed on the plurality of transmission gears 412, so that when the second bevel gear 404 rotates, the second transmission shaft 411 installed thereon rotates synchronously, so that the plurality of transmission gears 412 installed on the second transmission shaft 411 rotate and push the rack 413 to move toward the door frame 1 until it is inserted into the door frame 1, thereby realizing secondary locking of the door frame 1 and the door leaf 2, and improving the anti-theft performance of the security door.

[0035] Reference Fig.10 In this embodiment, a plurality of racks 413 are installed with sliders 414, and a plurality of slide grooves 415 are opened on the cavity 3. The sliders 414 are slidably adapted on the slide grooves 415, so that the plurality of racks 413 can be slidably connected to the cavity 3 through the sliders 414, so that when the transmission gear 412 pushes the rack 413 to move, the rack 413 can only move along the direction of the slider 414, thereby providing a guarantee for the rack 413 to move into the door frame 1.

[0036] Reference Figure 4-5In this embodiment, two connecting seats 416 are installed on the cavity 3, and two limiting rings 417 are installed on the second transmission shaft 411. Two rotating grooves 418 are provided on the two connecting seats 416. The rotating grooves 418 are adapted to the limiting rings 417, so that the second transmission shaft 411 can be rotatably connected to the two connecting seats 416 through the setting of the rotating grooves 418 and the limiting rings 417, so that the connecting seats 416 provide support force for the second transmission shaft 411, thereby improving the stability of the second transmission shaft 411.

[0037] Reference Figure 6 In this embodiment, the top of the second transmission shaft 411 is threadedly connected to a second lock plate 419, and a plurality of second lock tongues 420 are installed on the second lock plate 419, so that when the second transmission shaft 411 rotates, the second lock plate 419 threadedly connected thereto is driven to move upward, thereby moving the plurality of second lock tongues 420 installed on the second lock plate 419 into the door frame 1, thereby locking the door leaf 2 and the top of the door frame 1, further improving the anti-theft performance of the security door.

[0038] Reference Figure 6 In this embodiment, a limiting shaft 421 is installed on the top of the cavity 3, and the end of the second lock plate 419 away from the second transmission shaft 411 is slidably connected to the second lock plate 419, so that when the second transmission shaft 411 drives the second lock plate 419 to move, since the second lock plate 419 is slidably connected to the limiting shaft 421, the second lock plate 419 can only maintain vertical up and down movement, thereby limiting the moving direction of the second lock plate 419.

[0039] Reference Figure 6 In this embodiment, a plurality of slots 422 are provided at corresponding positions of the door frame 1 and the door leaf 2, and a plurality of first lock tongues 408, second lock tongues 420 and racks 413 are respectively slidably connected in the corresponding slots 422, so that the plurality of first lock tongues 408, second lock tongues 420 and racks 413 can pass through the corresponding slots 422 through the side walls of the door leaf 2 and thus be inserted into the slots 422 on the door frame 1, thereby completing the locking between the door leaf 2 and the door frame 1, thereby achieving the anti-theft effect of the security door.

[0040] Reference Figure 6-8In this embodiment, the door closing sensing mechanism 5 includes a mounting groove 501 provided on the door frame 1, a connecting shaft 502 is slidably mounted on the mounting groove 501, a connecting rod 503 is mounted on the bottom end of the connecting shaft 502, a third transmission shaft 504 is mounted on the end of the connecting rod 503 away from the connecting shaft 502, the bottom end of the third transmission shaft 504 is rotatably mounted on the cavity 3, and a first transmission wheel 505 is mounted on the lower part of the third transmission shaft 504, a transmission belt 506 is transmission-connected to the first transmission wheel 505, a second transmission wheel 507 is transmission-connected to the transmission belt 506, the second transmission wheel 507 is mounted on the upper end of the second transmission shaft 411, and the diameter of the second transmission wheel 507 is larger than that of the first transmission wheel 505.

[0041] When the second transmission shaft 411 rotates, the second transmission wheel 507 installed thereon rotates synchronously, so that the first transmission wheel 505 connected to the second transmission wheel 507 through the transmission belt 506 rotates, thereby driving the connecting rod 503 to rotate, thereby driving the door leaf 2 to rotate through the connecting rod 503, causing the door leaf 2 to be embedded in the door frame 1, thereby completing the automatic closing of the security door; since the diameter of the second transmission wheel 507 is larger than that of the first transmission wheel 505, after the anti-theft mechanism 4 is started, the power on it is transmitted to the first transmission wheel 505 through the second transmission wheel 507, causing the closing speed of the door closing sensing mechanism 5 to be faster than the speed at which the anti-theft mechanism 4 fully locks the security door, thereby completing a seamless connection from closing the door to locking and anti-theft.

[0042] Reference Figure 1 , Figure 6 In this embodiment, a display screen 508 is installed on the door leaf 2, and a flame sensor 509 is installed on the display screen 508. The flame sensor 509 and the servo motor 402 are connected to the same control system, and the system is connected to a face recognition system, so that when a flame occurs, it can be recognized by the flame sensor 509, thereby triggering the servo motor 402 to work and automatically close and lock the security door, thereby preventing the fire from spreading to the room and causing casualties, thereby improving the safety of residents' lives and property; the setting of the face recognition system enables residents to quickly unlock the door, further improving the practicality and convenience of the security door.
