[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3A corrosion-resistant high-protection cabinet lock includes a protective shell 1 and a fingerprint identifier 5 located on the cabinet. It is supplemented that the cabinet is opened by the fingerprint identifier 5 in the prior art. A through hole 2 corresponding to the fingerprint identifier 5 is opened on the protective shell 1, and a corresponding upper hole 3 and lower hole 4 are opened on the protective shell 1. The material of the protective shell 1 and the protective plate 10 is an iron alloy. By using the material of the protective shell 1 and the protective plate 10 as an iron alloy, the protective shell 1 and the protective plate 10 can be prevented from being greatly deformed by external force, and the upper hole 3 and the lower hole 4 are vertically opened from top to bottom;

[0022] The cabinet and the protective shell 1 are respectively fixedly mounted with a matching controller 6 and a face recognition system 7. A guide rod 8 is fixedly mounted in the upper hole 3, and a rack 9 is movably sleeved on the guide rod 8. A protective plate 10 extending into the lower hole 4 and used to protect the fingerprint identifier 5 is integrally connected to the rack 9. Figure 2 As shown, the guide rod 8 is vertically arranged, and the protective plate 10 is vertically arranged at one side of the fingerprint identifier 5. The protective plate 10 can seal the through hole 2 and extend into the lower hole 4 when it moves, so that the protective housing 1 and the protective plate 10 can protect the fingerprint identifier 5, which can avoid damage to the fingerprint identifier 5 caused by violent disassembly, and can also protect the precision equipment in the cabinet;

[0023] It should be noted that the specific model specifications of the fingerprint recognition device 5, the face recognition system 7, the controller 6, and the motor 11 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated;

[0024] A motor 11 opened and closed by a controller 6 is fixedly installed in the protective housing 1, and a rotating shaft 12 connected to a rack 9 is fixedly connected to the output end of the motor 11. The rotating shaft 12 is horizontally arranged, and a gear 13 meshing with the rack 9 is fixedly installed on the rotating shaft 12. A screw rod 14 connected to the rotating shaft 12 is rotatably installed in the protective housing 1. The screw rod 14 is horizontally arranged at one side of the rotating shaft 12, and a transmission belt 15 is connected between the rotating shaft 12 and the screw rod 14. The transmission belt 15 adopts a synchronous belt. The synchronous belt has the advantages of compact structure and non-slip, so that the rotating shaft 12 and the screw rod 14 can rotate at the same speed;

[0025] The movable sleeve on the screw rod 14 is provided with a matching and integrally connected nut 16, a limit frame and a bracket 17. A guide rod for limiting the limit frame is fixedly installed on the protective shell 1, and the bracket 17 is vertically arranged above the fingerprint identifier 5. A cleaning cloth 18 for wiping fingerprints is embedded in the bracket 17. The guide rod guides the limit frame and the nut 16. The nut 16 drives the bracket 17 and the cleaning cloth 18 to wipe the fingerprints and sweat remaining on the fingerprint identifier 5 when moving, which can prevent the loss of fingerprints, thereby ensuring the overall safety performance of the cabinet.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When the cabinet is closed;

[0028] The controller 6 immediately controls the motor 11 to drive, and the output end of the motor 11 drives the shaft 12 to rotate counterclockwise, and the shaft 12 drives the gear 13 to pull the rack 9, so that the rack 9 drives the protection plate 10 to slide on the guide rod 8, and the protection plate 10 can extend into the lower hole 4 when sliding to protect the fingerprint identifier 5;

[0029] At the same time, the rotating shaft 12 drives the screw rod 14 to rotate through the transmission belt 15, so that the screw rod 14 drives the nut 16 and the limit frame to move horizontally under the guidance of the guide rod. When the nut 16 moves horizontally, it drives the bracket 17 and the cleaning cloth 18 to wipe the fingerprint and sweat on the fingerprint identifier 5 when moving;

[0030] When the cabinet needs to be opened;

[0031] The face recognition system 7 verifies the operator and sends a command to the controller 6 when the verification is successful, so that the controller 6 turns on the motor 11;

[0032] The output end of the motor 11 drives the rotating shaft 12 to rotate clockwise, so that the protective plate 10 can be moved into the upper hole 3. The operator extends his finger to the fingerprint identifier 5 through the through hole 2, so as to open the cabinet.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
