Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A high-security anti-theft door, comprising a door frame 1 and an anti-theft door 2.

[0024] The security door 2 consists of a front door 21, a rear door 23, and a handle. The pin of the front door 21 is installed on the left side of the door frame 1, and the pin of the rear door 23 is installed on the right side of the door frame 1. A storage frame 3 is fixedly installed on the door frame 1. The front door 21 and the rear door 23 are equipped with roller shutter doors 22 that cooperate with the key. The storage frame 3 is equipped with a storage tube 4 that cooperates with the roller shutter doors 22. The cooperation of the front door 21, the roller shutter doors 22, and the rear door 23 can increase the security performance of the security door 2, and the roller shutter doors 22 can be opened with the key.

[0025] The storage box 3 is located at the top of the door frame 1. The roller shutter door 22 is vertically located between the front door 21 and the rear door 23. The front door 21 is equipped with an electronic lock 5 connected to the handle and a front-facing camera 6.

[0026] A fingerprint unlocker 7 is provided on the door frame 1, and a through hole 8 corresponding to the fingerprint unlocker 7 is provided on the rear door 23. The person opening the door extends their finger through the through hole 8 to the fingerprint unlocker 7. After the fingerprint unlocker 7 matches the fingerprint, it can open the rear door 23. Furthermore, by placing the fingerprint unlocker 7 inside the door frame 1, the fingerprint unlocker 7 is not affected by external force. A protective structure is provided on the front door 21 to protect the electronic lock 5 and the front camera 6.

[0027] The protective structure includes a protective cover 9 fixedly installed on the front door 21. The electronic lock 5 and the front-facing camera 6 are located inside the protective cover 9. A protective plate 10 and a support plate 11 are slidably fitted inside the protective cover 9. A movable plate 12 is fixedly installed on the protective plate 10. A contact rod 13 that moves against the movable plate 12 is fixedly installed on the support plate 11. By setting the electronic lock 5 and the front-facing camera 6 inside the protective cover 9, the front-facing camera 6 will first perform facial unlocking. After facial unlocking, it can send a signal to the controller 16, so that the protective plate 10 can move up again to perform password unlocking. If the facial recognition of the person opening the door is inaccurate, it will not send a signal to the controller 16, but will send a signal to the mobile terminal through a remote device and record the face of the person opening the door through the front-facing camera 6.

[0028] The protective plate 10 is provided with a handle extending outside the protective cover 9. The protective cover 9 has a U-shaped structure. The protective plate 10 is vertically arranged at the front of the protective cover 9, and the support plate 11 is horizontally arranged at one side of the protective plate 10. The protective cover 9 has a guide groove for guiding the support plate 11. The guide groove guides the support plate 11, so that the support plate 11 can smoothly pull the abutment rod 13 and the rack 14 when it moves.

[0029] The protective cover 9 is provided with an adjustment structure for adjusting the height of the support plate 11.

[0030] The adjustment structure includes a rack 14 fixedly mounted on a support plate 11. A controller 16 and a motor 15, electrically connected to the front-facing camera 6, are fixedly mounted inside the protective cover 9. The output end of the motor 15 is fixedly connected to a rotating shaft 17 that is drively connected to the rack 14. The rotating shaft 17 is horizontally positioned, and a gear 18 that meshes with the rack 14 is fixedly mounted on the rotating shaft 17. (According to the attached instruction manual...) Figure 6 As shown, when the rack 14 moves to the highest position, it will not extend beyond the protective cover 9. When the support plate 11 moves to the highest position, the electronic lock 5 can be exposed, and the person opening the door can open the front door 21 through the electronic lock 5.

[0031] It should be noted that the specific models and specifications of the storage tube 4, electronic lock 5, front camera 6, fingerprint unlocker 7, controller 16, and motor 15 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] When the security door 2 is opened, the handle is pulled out, and the handle drives the protective plate 10 to open the protective cover 9. When the protective plate 10 moves upward, it drives the moving plate 12 to move and abut against the contact rod 13, thus limiting the upward movement height of the protective plate 10. The front camera 6 scans the operator's face. After the front camera 6 completes the scan, it determines the identity of the person opening the door and immediately sends a signal to the controller 16.

[0034] The controller 16 sends a command to the motor 15. The output end of the motor 15 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the gear 18 to pull the meshing rack 14. The rack 14 drives the support plate 11 to slide in the guide groove. After the support plate 11 moves up, it drives the abutment rod 13 to move up and disconnects from the moving plate 12. The person opening the door continues to manually pull out the handle so that the protective plate 10 opens the protective cover 9.

[0035] The person opening the door inputs the password into the electronic lock 5. After the password is correct, they open the front door 21 through the handle, insert the key into the bottom position of the roller shutter 22 to unlock it, and raise the roller shutter 22 so that it is stored in the storage tube 4. The person opening the door extends their finger through the through hole 8 to the fingerprint unlocker 7. The fingerprint unlocker 7 confirms the identity of the person opening the door and applies pressure to the rear door 23 to open the security door 2.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
