[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an intelligent security door capable of automatic locking includes an intelligent security door body 1. A slot 101 is formed on one end surface of the intelligent security door body 1. An installation plate 2 is installed inside the slot 101. Several fixing bolts 201 for position fixing are installed on the surface of the installation plate 2. An installation groove 102 is formed on the inner wall of one end of the slot 101. An installation box 3 is installed on one side surface of the installation plate 2. A self-locking mechanism 4 is provided inside the installation box 3. The installation box 3 is located inside the installation groove 102. Sliding strips 301 are installed on both the upper and lower end surfaces of the installation box 3. Sliding grooves that slide with the sliding strips 301 are formed on the inner walls of both the upper and lower end surfaces of the installation groove 102.

[0027] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the self-locking mechanism 4 includes a displacement sensor 401, a moving plate 402, and a built-in power supply 403. The displacement sensor 401 is mounted on one side surface of the mounting plate 2. The moving plate 402 is disposed inside the mounting box 3. The built-in power supply 403 is mounted on the bottom inner wall of the mounting box 3. A controller 412 is mounted on the top of the built-in power supply 403. Several locking rods 404 are evenly distributed on one side surface of the moving plate 402. One end of each locking rod 404 is inserted into the mounting plate 2. A mounting bracket 405 is mounted on one side inner wall of the mounting box 3. A servo motor 406 is mounted on one end surface of the mounting bracket 405. The output end of the servo motor 406 is mounted on... A rotating rod 407 is provided, one end of which is rotatably mounted on the inner wall of one side of the mounting box 3. A transmission gear 408 is fixedly mounted on the rod body of the rotating rod 407. A side plate 409 is mounted on the top of one side surface of the moving plate 402. A rack 410 is mounted on one side of the lower surface of the side plate 409. The rack 410 meshes with the transmission gear 408. Guide grooves 302 are provided on the inner walls of both the upper and lower ends of the mounting box 3. Limiting sliders 411 that slide in cooperation with the guide grooves 302 are installed on the upper and lower surfaces of the moving plate 402 and the upper surface of the side plate 409. The displacement sensor 401, servo motor 406, controller 412 and built-in power supply 403 are all electrically connected.

[0028] Through the meshing transmission between the transmission gear 408 and the rack 410, the locking rod 404 can be extended and retracted under the drive of the servo motor 406. The displacement change monitored by the displacement sensor 401 can be converted into an electrical signal by the controller 412, and then the servo motor 406 can be controlled to work, thereby automatically locking the door without manual operation. Through the sliding cooperation between the limit slider 411 and the guide groove 302, the movement trajectory of the moving plate 402 and the side plate 409 can be limited, which can improve the stability during the movement process and prevent position deviation.

[0029] The working principle of this type of intelligent security door that can automatically lock:

[0030] In use, the displacement sensor 401 detects the position of the latch of the main body 1 of the smart security door. When the movement of the latch is detected, the signal is transmitted to the controller 412, which controls the servo motor 406 to rotate. This causes the rotating rod 407 to drive the transmission gear 408 to rotate. Under the meshing action between the transmission gear 408 and the rack 410, the side plate 409 can be moved, which can extend the locking rod 404 out of the mounting plate 2 and move it into the corresponding slot inside the door frame, thereby completing the door's deadbolt locking. This eliminates the need for manual deadbolt locking and improves the safety of use. During unlocking, the same principle applies: the movement of the latch is detected, and the locking rod 404 is reset by driving the servo motor 406. The servo motor 406, controller 412 and displacement sensor 401 are powered by the built-in power supply 403. The mounting plate 2 and mounting box 3 can be disassembled by installing and removing the fixing bolt 201, which is convenient for maintenance and power supply replacement. The position of the mounting box 3 inside the mounting groove 102 can be limited by the cooperation between the sliding strip 301 and the sliding groove, so that there will be no shaking when the door rotates.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
