[0021] Example
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a special lock for a supervision place with a door access control function, comprising a protective shell 1, a first forward and reverse motor 8 is arranged on the bottom surface of the inner part of the protective shell 1, a bidirectional threaded screw 9 is connected to the output end of the first forward and reverse motor 8, a first moving block 11 and a second moving block 12 are respectively threadedly connected on the rod body of the bidirectional threaded screw 9, the first moving block 11 and the second moving block 12 are also slidably connected to a guide rod 10, and the guide rod 10 is fixed inside the protective shell 1, and the first moving block 11 is provided with two first Connecting rod 7, two first connecting rods 7 extend out of the protective shell 1 at one end away from the first moving block 11, and the end is connected to the outer baffle 5 of the protective shell 1, two second connecting rods 13 are arranged on the second moving block 12, and cameras 14 are installed at one end of the two second connecting rods 13 away from the second moving block 12, an access control card reader 2 is installed on the outside of the protective shell 1, and an access control controller 16 is installed inside the protective shell 1, and external threads in opposite directions are respectively arranged at both ends of the bidirectional threaded screw 9, and the two sections of the external threads are threadedly connected to the second moving block 12 and the first moving block 11 from top to bottom.
[0023] In this embodiment, the staff first uses the access card reader 2 to unlock the door. After the access controller 16 receives the signal from the access card reader 2, it immediately starts the first forward and reverse motor 8 to drive the bidirectional threaded screw 9 to start rotating. This action synchronously drives the rotation of the first moving block 11 and the second moving block 12, which are respectively threadedly connected to the external threads of the bidirectional threaded screw 9 in different directions. Since the two moving blocks are slidably connected to the guide rod 10, the drive of the first forward and reverse motor 8 enables the first moving block 11 and the second moving block 12 to move closer to or away from each other at the same time. This action prompts the outer baffle 5 to slide downward, thereby exposing the access controller 16, so that the staff can enter the access code again to unlock the door lock. At the same time, the camera 14 located at the top also extends upward from the protective shell 1 to start recording and identify the staff. This multiple authentication mechanism significantly improves the security of the access control. The access controller 16 is installed inside the protective shell 1 and is not exposed under normal conditions. Therefore, it is not easily damaged by external forces, which provides convenience for the normal use of the staff.
[0024] The access control controller 16 includes an unlocking controller, a password button, a display screen and a fingerprint reader. Two slide grooves 6 are provided on the outer shell surface of the protective shell 1 under the baffle 5. The baffle 5 is slidably connected in the slide groove 6. An embedded plate 3 is provided at the end of the camera 14 away from the second moving block 12. The embedded plate 3 is slidably connected in the square hole reserved at the top of the protective shell 1. A window 4 is provided on the outer shell of the protective shell 1 close to the baffle 5. The window 4 is located directly in front of the access control card reader 2.
[0025] In this embodiment, the slide groove 6 makes the up and down movement of the baffle plate 5 smoother and more stable, the embedded plate 3 plays a role in protecting the camera 14, and the window 4 reserves a working space for the access control controller 16.
[0026] A second forward and reverse motor 18 is fixed inside the protective shell 1, and a gear 19 is installed at the end of the output shaft of the second forward and reverse motor 18. The gear 19 is meshed and connected to a rack 20, and the rack 20 is set on a locking rod 21. The locking rod 21 is slidably connected to a fixing ring 22, and a lock hole 23 is correspondingly opened near the locking rod 21 of the protective shell 1.
[0027] In this embodiment, after the access control controller 16 is unlocked again, the second forward and reverse motor 18 is started through the unlocking controller, and the second forward and reverse motor 18 drives the gear 19 to rotate. At the same time, the gear 19 and the rack 20 are meshed and connected, so that the locking rod 21 can be driven to slide on the fixing ring 22 and slide out from the lock hole 23 or retracted into the protective shell 1, thereby completing the unlocking or locking.
[0028] The bidirectional threaded screw 9 is rotatably connected in the bearing seat 15 , and the bearing seat 15 is fixed inside the protective housing 1 . Limit blocks 17 are provided at the ends of the bidirectional threaded screw 9 and the guide rod 10 .
[0029] In this embodiment, the bearing seat 15 plays a supporting and fixing role, and the limit block 17 can prevent the two moving blocks from slipping off the bidirectional threaded screw 9 and the guide rod 10.
