[0024] like Figures 1 to 5 As shown

[0025] An airport RFID-based high-protection smart key cabinet includes a cabinet body 1. A mounting slot 5 is provided on one side of the cabinet body 1. A display screen 12, a fingerprint reader 13, and an RFID reader 14 are sequentially arranged from top to bottom within the mounting slot 5. A protective door 4 is slidably mounted on one side of the mounting slot 5. The protective door 4 protects the display screen 12, fingerprint reader 13, and RFID reader 14 from damage caused by impacts from external objects. A connecting bracket 19 is fixedly installed on one side of the protective door 4, and a push-pull handle 6 is fixedly connected to the outer wall of one side of the protective door 4. A connecting bracket 19 is also fixedly connected to the outer wall of one side of the push-pull handle 6. A fixed rod 18 and a connecting bracket 19 are fixedly connected to the end of the fixed rod 18. A mounting rail 8 is fixedly connected to one outer wall of the cabinet 1. A mounting bracket 11 is slidably mounted on the mounting rail 8. A guide block 17 is slidably connected to the inner wall of the mounting rail 8. The mounting bracket 11 is fixedly connected to one outer wall of the guide block 17. A guide rod 10 is hinged to the mounting bracket 11. One end of the guide rod 10 is hinged to the connecting bracket 19. A positioning groove 20 is opened on the bottom outer wall of the mounting bracket 11. Symmetrically arranged mounting seats 9 are fixedly connected to one outer wall of the cabinet 1. Each mounting seat 9 has a movable groove 21 on its top. A positioning block 15 is slidably mounted on the inner wall of each movable groove 21. The tops of the two positioning blocks 15 are opposite each other. Both sides are sloped, and the two positioning blocks 15 are symmetrical to each other and are adapted to the positioning grooves 20. Compression springs 22 are fixedly connected to the inner bottom walls of the two movable grooves 21. The tops of the two compression springs 22 are respectively fixedly connected to the outer bottom walls of the two positioning blocks 15. When the key needs to be retrieved, the positioning blocks 15 are moved out of the positioning grooves 20, releasing the restriction on the mounting bracket 11. After the positioning blocks 15 are moved out of the positioning grooves 20, the protective door 4 is pulled to move, and the protective door 4 drives the connecting bracket 19 to move. The connecting bracket 19, in conjunction with the mounting bracket 11, changes the tilt angle of the guide rod 10. When the tilt angle of the guide rod 10 changes, the mounting bracket 11, in conjunction with the mounting bracket 11, changes the tilt angle of the guide rod 10. The guide block 17 and the mounting rail 8 enable the guide rod 10 to move the mounting frame 11. When the mounting frame 11 moves to contact another positioning block 15, it presses the positioning block 15 downward until the positioning groove 20 at the bottom of the mounting frame 11 moves directly above the positioning block 15. At this time, under the action of the compression spring 22, the positioning block 15 can be pushed into the positioning groove 20, thereby achieving the positioning function of the mounting frame 11. At this time, the guide rod 10 and the connecting frame 19 are limited and stop moving, achieving the positioning effect of the protective door 4, so that the protective door 4 can be opened, making it convenient for staff to identify themselves through the fingerprint reader 13 or RFID reader 14 set in the mounting groove 5.

[0026] In a specific implementation, a cabinet door with a smart lock is installed on one side of the cabinet 1, and the cabinet door is located on one side of the receiving slot 2. Inside the cabinet 1, key holders 3 with RFID tags are evenly distributed. Keys are stored through the receiving slot 2 and key holders 3. Staff identify themselves using a fingerprint reader 13 or an RFID card reader 14. After successful authentication, the cabinet door unlocks and automatically pops open, allowing staff to remove the designated key from the key holder 3 with the RFID tag. Symmetrically arranged guide grooves 16 are provided on the inner wall of the opposite side of the mounting slot 5. The protective door 4 is fixed on both the upper and lower sides. The cabinet 1 is connected with symmetrically arranged guide strips 7, which are slidably connected to the inner wall of the guide groove 16. A receiving groove 2 is provided on one side of the cabinet 1. A key hanging seat 3 is provided on the inner side of the receiving groove 2. A rectangular movable opening 23 is provided on one side of each of the two mounting seats 9. The rectangular movable opening 23 is connected to the movable groove 21. A pressing block 24 is slidably connected to the inner wall of each of the two rectangular movable openings 23. One end of the pressing block 24 is fixedly connected to the outer wall of the positioning block 15. When the key needs to be taken out, the pressing block 24 is pressed and moved downward. The pressing block 24 drives the positioning block 15 to move downward, so that the positioning block 15 is disengaged from the positioning groove 20.

[0027] The implementation principle of an airport RFID-based high-protection smart key cabinet in this embodiment is as follows:

[0028] In practical use, the key is stored in the designated receiving slot 2 and key hanging seat 3. The designated protective door 4 protects the display screen 12, fingerprint reader 13, and RFID reader 14 from damage caused by external objects. When the key needs to be retrieved, the pressing block 24 is pressed down, which moves the positioning block 15 down, causing it to disengage from the positioning slot 20. After the positioning block 15 disengages from the positioning slot 20, the protective door 4 is pulled to move, which in turn moves the connecting frame 19. The connecting frame 19, in conjunction with the mounting bracket 11, changes the tilt angle of the guide rod 10. When the tilt angle of the guide rod 10 changes, the guide block 14... 7 and the mounting rail 8 enable the guide rod 10 to move the mounting frame 11. When the mounting frame 11 moves to contact another positioning block 15, it presses the positioning block 15 downward until the positioning groove 20 at the bottom of the mounting frame 11 moves directly above the positioning block 15. At this time, under the action of the compression spring 22, the positioning block 15 can be pushed into the positioning groove 20, realizing the positioning function of the mounting frame 11. At this time, the guide rod 10 and the connecting frame 19 are limited and stop moving, achieving the positioning effect of the protective door 4, so that the protective door 4 can be opened, making it convenient for staff to identify their identity through the fingerprint reader 13 or RFID reader 14 set in the mounting groove 5. After the identity verification is passed, the cabinet door unlocks and pops open automatically, and then the staff can take the designated key from the key hanging seat 3 with the RFID exclusive tag.
