[0057] Multiple limiting grooves 701 are opened on the side wall of the limiting disk 7, and the multiple limiting grooves 701 are evenly arranged circumferentially along the limiting disk 7; the limiting component includes a limiting pin 11, the limiting pin 11 is movably connected to the front lock body mounting plate 2, the position of the limiting pin 11 corresponds to the limiting groove 701, and the limiting pin 11 is provided with a corresponding driving component to drive the limiting pin 11 to move. The front electronic key input panel 202 and the rear electronic key input panel 103 can both be controlled by the controller to control the driving component.

[0058] In some embodiments, the drive component is an electric cylinder, the housing of which is fixedly connected to the front lock body mounting plate 2, and the output shaft of which is fixedly connected to the limit pin 11.

[0059] In other embodiments, the drive assembly includes a motor 10, a swing arm 8, and a mechanical lock cylinder 9. The middle end of the swing arm 8 is hinged to the front lock body mounting plate 2. The housing of the motor 10 is fixedly connected to the front lock body mounting plate 2.

[0069] The controller, motor 10, mechanical lock cylinder 10, and power supply are installed inside the front housing 201. The controller uses, but is not limited to, the existing DAXINGMEI smart door lock control board model DAM-LOCK-B1. The mechanical lock cylinder 10 uses, but is not limited to, the existing lock cylinder with a rotating shaft. The motor 10 uses, but is not limited to, the existing DC motor 10. The power supply uses, but is not limited to, the existing 6V dry cell battery. The front electronic key input panel 202 and the rear electronic key input panel 103 use, but are not limited to, the existing digital membrane key switch. The power supply provides power to the controller, motor 10, front electronic key input panel 202, and rear electronic key input panel 103. The controller controls the motor 10 to rotate after the correct password is entered into the front electronic key input panel 202 and the rear electronic key input panel 103, which is existing technology. The specific structure and connection form will not be described here.

[0070] Work process:

[0071] When implementing this solution, the front lock body mounting plate 2 and the rear lock body mounting plate 1 are installed on the outside and inside of the door body, respectively. Then, the front housing 201 and the rear housing 101 are installed. The directional rod is inserted into the square groove to realize the synchronous rotation of the front handle 5 and the handle. The latch plate 3 is installed according to the position of the latch 4.

[0072] When the door lock is opened from the outside, the password is entered on the front electronic key input panel 202. After the password is correct, the controller controls the motor 10 to rotate counterclockwise. The vertical rod slides in the adjacent spring coil of the compression spring. Under the driving action of the vertical rod, the compression spring moves to the side of the vertical rod near the motor 10 and drives the mounting base 13 to move away from the limit plate 7 until the limit pin 11 disengages from the limit groove 701. At this time, the drive rod can rotate.

[0073] When the door lock is opened from the inside, the steps are similar to those described above after entering the password on the rear electronic key input panel 103, and will not be repeated here.

[0074] By installing an electronic key input panel on the outside of the door, the courtyard door can be opened even if the key is forgotten, improving the convenience of using the courtyard lock. The unlocking process is even more convenient with the electronic key input panel 103 installed on the inside of the door.
