When the lock core is in an original state and the outdoor knob 3 is screwed, the lock core can idle at any angle in a forward unlocking direction (which can be clockwise or anticlockwise, and the unlocking direction of the lock body is defined as the forward direction) but cannot be unlocked, and can be reversely locked by reverse rotation; the indoor knob 26 can be rotated in any state to unlock the lock positively and reversely. The lock core has the following functions:

1. the anti-theft triggering alarm function:

as shown in fig. 3, when a mechanical key 1 or other unlocking tool is inserted into the cylinder assembly 2 and touches the contact pin 7, the inserted object touches the housing to form a ground, and a signal is transmitted to the main board 12 through the contact pin 7, the contact spring 8 and the conduction ring 5. The contact spring 7, the contact spring 8 and the conducting ring 5 are always connected with the signal end in the main board 12.

2. Direct reverse rotation and reverse locking functions:

as shown in fig. 4, when the outdoor knob 3 is rotated in the forward direction, the connecting pin 15 will retract into the pin hole of the lock cylinder rotating member 13 along the slope feature in the lock shaft rotating member 18, and at this time, the external rotation cannot drive the lock shaft rotating member 18 to rotate idle, and the door cannot be opened; when the outdoor knob 3 is rotated reversely, the connecting pin 15 will contact with the straight body surface of the lock shaft rotating piece 18 to form stress, and at this time, the external rotation directly drives the lock shaft rotating piece 18 to connect the dial 27 for reverse locking.

3. The mechanical key opens the door:

when the correct mechanical key 1 is inserted, the blades in the lock cylinder assembly 2 are completely matched, the lock cylinder side column 10 falls into the blade groove, the outer circular surface of the lock cylinder assembly 2 is changed into a sunken state from an original parallel and level, the idle rotation side column piece 11 is under the spring action of the grounding probe on the main board 12 and enters the lock cylinder side column groove and is connected with a notch of the lock cylinder connecting piece 16, at the moment, the mechanical key 1, the lock cylinder assembly 2, the lock cylinder connecting piece 16 and the pull-and-drag 27 are connected into an integral transmission, and unlocking can be realized by directly screwing the key. When the dislocated mechanical key is inserted, the internal parts keep the original state, and the unlocking direction is an idle state and can not drive the pulling device 27.

4. Wireless unlocking step:

1) the mobile phone is connected with the electronic circuit embedded in the lock cylinder in a wireless mode.

2) The mobile phone end sends a door opening signal to the main board 12 in the lock cylinder.

3) The main board 12 controls the rotational movement of the motor 23 inside the key cylinder.

4) As shown in fig. 5, the motor screw 22 is driven to rotate forward by controlling the forward rotation motion of the motor 23, the pushing piece 21 moves towards the direction of the indoor knob 26 under the screw thread rotation of the motor screw 22 and stops after the distance between the pushing piece and the step surface screw thread length of the lock shaft 24, the motor 23 idles to be powered off, the electronic unlocking control pin 19 moves along with the pushing piece under the action of the pin spring 14, meanwhile, the connecting pin 15 can smoothly enter the pin hole of the lock shaft rotating piece 18, the lock core rotating piece 13 is connected with the lock shaft rotating piece 18, and the poking pull 27 can be driven to unlock by screwing the outdoor knob 3 at the moment.

5) Within a certain time after the door is opened, the forward rotation motion of the motor 23 drives the motor screw 22 to rotate forward, the pushing piece 21 moves towards the outdoor knob 3 under the screw thread rotation of the motor screw until the pushing piece contacts with the step surface of the lock shaft 24, the electronic unlocking control pin 19 is driven and the connecting pin 15 is pushed into the pin hole of the lock core rotating piece 13 when the pushing piece 21 is displaced, the lock core rotating piece 13 and the lock shaft rotating piece 18 are in a separated state, and the outdoor knob 3 cannot be driven to pull the pull tab 27 to unlock by screwing at the moment.
