Description
Technical Field
The invention relates to a lock core.
Background
A lock core for an intelligent lock (such as a fingerprint lock, a magnetic card lock and a coded lock) on the market drives a tail ruler component to rotate by controlling a motor through an intelligent control system, the tail ruler component is matched with a shifting sleeve, and the shifting sleeve rotates along with the rotation of the tail ruler component to realize unlocking. The lock core can be manually unlocked outside a door through a key, when the key is inserted into the unlocking state of the locking mechanism, the key pushes the lock core clutch component to be matched with the shifting sleeve, the tail ruler component is pushed away from the shifting sleeve, the lock core is rotated, the lock core drives the lock core clutch component to rotate, and the lock core clutch component drives the shifting sleeve to rotate so as to realize unlocking. Such lock cylinders have some significant drawbacks. Firstly, if someone inserts foreign matters into the key hole, on one hand, the foreign matters can enter the deep part of the lock cylinder without blocking, and are difficult to take out or maintain; on the other hand, the foreign matter probably leads to the tail chi subassembly and dials the cover separation, and at the house starter motor this moment, the motor drives the idle running of tail chi subassembly, can't unblank, if the foreign matter can't take out, the lock just is scrapped. Secondly, after the key is inserted into the key hole, if the key is not pulled out, people in the room can not open the door. The key is inserted into the lock cylinder to open the door if manual unlocking is carried out outside the door, and the door is closed if the key is forgotten to be pulled out, so that the key can be in two states, namely the key is in the unlocking state or in the unlocking state, namely the lock cylinder can rotate in the lock shell; secondly, the key is in the state of not unblanking, namely the lock courage can not rotate in the lock shell. For the first state, the key pushes the lock cylinder clutch assembly to the direction of the shifting sleeve and pushes the tail ruler assembly to be separated from the shifting sleeve, at the moment, the motor is started to rotate in a room, the motor rotates to drive the tail ruler assembly to rotate, and the tail ruler assembly is separated from the shifting sleeve, so that the tail ruler assembly can only idle and cannot be unlocked; for the second state, the key is not in the state of unblanking, then the lock courage can not be rotatory in the lock shell, though the tail chi subassembly has some to match with dialling the cover this moment, because the key has withstood lock courage clutch module, the spring in the tail chi subassembly can't push away lock courage clutch module and dial the cover, the lock courage still has some to match with dialling the cover this moment, do not totally separate, consequently dial the cover by the lock courage card die can not rotate, instruction motor rotates this moment, dial the cover and match with the tail chi subassembly, the tail chi subassembly can not rotate, lead to unable the unblanking. For some old people or children, the door can be easily closed by forgetting to pull out the key after being opened by the key, and at the moment, the door cannot be unlocked in the room in an electric mode, and people need to be called to open the door outside, so that unnecessary trouble is brought. Therefore, the prior art lock cylinder for the smart lock still remains to be improved.

The working principle of the invention is as follows:
1. manual unlocking process with key:
when the lock is locked, the locking mechanism is in a locking state, the lock cylinder clutch rotating piece shifting sleeve is separated, one part of the bulge 331 of the tail ruler clutch rotating piece is embedded with the bayonet 323 of the tail ruler rotating piece 32, the other part of the bulge 331 of the tail ruler clutch rotating piece is embedded with the groove 52 of the shifting sleeve, and the pin shaft 62 in the clutch limiting component 6 is positioned at the position A, close to the key hole, of the groove 11. When the key 9 is inserted into the keyhole 21 and is inserted into an unlocking state, namely, the front locking device and the side locking device are both in an unlocking state, then the key 9 is rotated, the lock cylinder rotates, the groove 11 rotates, the pin shaft 62 slides along the groove 11 because the pin shaft 62 is limited by the groove 13, so that the limit top piece 61 moves along the axial direction to the sleeve shifting direction, the limit top piece 61 pushes the pushing piece 42 to move along the axial direction to the sleeve shifting direction, the pushing piece 42 presses the second spring 43, meanwhile, because the notch 23 of the lock cylinder is embedded with the front part convex strip 412 on the lock cylinder clutch rotating piece 41, the lock cylinder clutch rotating piece 41 rotates along with the rotation of the lock cylinder when moving along the sleeve shifting direction, when the rear part convex strip 412 on the lock cylinder clutch rotating piece 41 aligns with the groove 52 in the sleeve, under the thrust of the second spring 43, the lock cylinder clutch rotating piece 41 moves towards the sleeve shifting direction and pushes the tail ruler clutch rotating piece 33 away from the sleeve shifting, that is, the protrusion 331 on the tail ruler clutch rotating piece 33 is separated from the groove 52 of the shifting sleeve, the protrusion 331 on the clutch rotating piece 33 is completely dropped into the bayonet 323 of the tail ruler rotating piece 32, at this time, the pin shaft 62 also reaches the position B1 or B2 of the groove 11, the lock cylinder drives the lock cylinder clutch rotating piece 41 to rotate by rotating the key, and the lock cylinder clutch rotating piece 41 drives the shifting sleeve to rotate, so that unlocking is realized.
2. The key is forgotten to be pulled out, and the door is closed and then is unlocked in the house:
the key is not pulled out, because the key 9 does not directly support the limit ejecting part 61, namely the key 9 does not form resistance to the limit ejecting part 61, therefore, no matter where the pin shaft 62 is located in the groove 11, the motor is started in a room, under the vibration of the motor and the thrust of the first spring 34, the pin shaft 62 can return to the part A of the groove 11, the bulge 331 of the tail ruler clutch rotating part 33 is embedded with the groove 52 of the shifting sleeve 5, the lock cylinder clutch rotating part 41 is supported away from the shifting sleeve, and the tail ruler rotating part 33 drives the shifting sleeve 5 to rotate, so that the lock can be unlocked.
3. Unlocking in the house under the condition that a person inserts a foreign body into the key hole:
after the foreign matter is inserted, the clutch limiting component 6 is arranged to block the further entering of the foreign matter, and the lock cylinder clutch rotating piece and the shifting sleeve are in a separated state, and the tail ruler component is embedded with the shifting sleeve, so that the tail ruler can be driven to be unlocked by the starting motor in the house.
