[0020] Please refer to Figures 1 to 3, in the embodiment of the present utility model, the intelligent access control device includes a door frame body 1. On one side of the door frame body 1, a mechanical door lock 2 and an access control controller 5 are connected by threads. On both sides of the mechanical door lock 2, there are a mechanical door lock rear plate 27 and a mechanical door lock front plate 28. The mechanical door lock rear plate 27 and the mechanical door lock front plate 28 are connected by bolts. Both the mechanical door lock rear plate 27 and the mechanical door lock front plate 28 are provided with lock holes 29. The access control controller 5 is located on top of the mechanical door lock 2. On both sides of the mechanical door lock 2, a first door handle 3 and a second door handle 4 are connected by threads. On one side near the bottom of the access control controller 5, there are a fingerprint identifier 6 and a doorbell 7. On one side near the top of the access control controller 5, there are physical buttons 8 and a display screen 9. The mechanical door lock 2 is provided with a door lock 10 and an anti-theft lock 11. The anti-theft lock 11 is located on one side at the bottom of the door lock 10. The first door handle 3 and the second door handle 4 pass through the mechanical door lock rear plate 27 and the mechanical door lock front plate 28 and are connected by threads to a first micro-motor 12. The access control controller 5 remotely controls the first micro-motor 12. The first micro-motor 12 is flange-connected to a crank 13. The crank 13 is slidably connected to a door lock fixing pin 15. The door lock fixing pin 15 is connected by threads to a door lock body 14. The door lock body 14 and the door lock 10 are welded together. On one side near the middle of the mechanical door lock front plate 28, there is a spring fixing shaft 17. The spring fixing shaft 17 is connected to a spring 16. The top of the spring 16 is adhesively connected to the door lock body 14.

[0021] Among them, on one side near the middle of the mechanical door lock front plate 28, there is a spring holder 18. The spring holder 18 is connected to a spring 19. The other side of the spring 19 is connected to a chuck 20. The chuck 20 is slidably connected to a stopper 21. The stopper 21 is installed on the mechanical door lock front plate 28. The anti-theft lock 11 is welded to an anti-theft lock body 22. The anti-theft lock body 22 is slidably connected to the stopper 21. The stopper 21 limits the moving distance of the anti-theft lock body 22 and the chuck 20. At the top of the anti-theft lock body 22, there is a locking groove connected to the chuck 20. At the bottom of the anti-theft lock body 22, there is a concave-convex structure. At the bottom of the mechanical door lock front plate 28, there is a second micro-motor 26. The access control controller 5 remotely controls the second micro-motor 26. The second micro-motor 26 is key-connected to a driving gear 25. The driving gear 25 is meshed with a driven gear 24. The driven gear 24 is bolted to a moving fork 23. The moving fork 23 is in contact connection with the concave-convex structure at the bottom of the anti-theft lock body 22. The moving fork 23 can squeeze the anti-theft lock body 22 to drive the anti-theft lock 11 to move.

[0022] The working principle of the present utility model is as follows: The doorbell 7 can be used to make the access control controller 5 emit a sound. The input button password can be manipulated through the physical button 8 on the display screen 9 or fingerprints can be entered through the fingerprint identifier 6. The anti-theft lock 11 of the mechanical door lock 2 is controlled by the physical button 8 and the fingerprint identifier 6 to open and close to achieve the access control effect. When the first door handle 3 or the second door handle 4 is rotated, the crank 13 is driven to rotate. The crank 13 squeezes the door lock fixing pin 15, and the door lock fixing pin 15 drives the door lock body 14 to move away from the door lock 10 to achieve the effect of opening the door. The first micro motor 12 is controlled by the physical button 8 and the fingerprint identifier 6 to drive the crank 13 to rotate to also achieve the effect of opening the door. When the first door handle 3 or the second door handle 4 is not rotated, the door lock body 14 moves towards the door lock 10 under the action of the tension spring 16 to achieve the closing effect. The forward and reverse rotation of the second micro motor 26 is controlled by the key or the physical button 8 and the fingerprint identifier 6. The second micro motor 26 drives the driving gear 25 to rotate forward and backward. The driving gear 25 meshes with and drives the driven gear 24 to rotate forward and backward. The driven gear 24 drives the moving fork 23 to rotate forward and backward. The moving fork 23 rotates forward and backward to squeeze the anti-theft lock body 22 to move. At the same time, the chuck 20 clamps the top of the anti-theft lock body 22 to achieve the effect of access control closing and opening.

[0023] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
