Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the lock cylinder mechanism in this embodiment includes an accommodating cylinder 1, where the accommodating cylinder 1 is a cylindrical cylinder, the accommodating cylinder 1 is provided with a slot 11 along an axial direction thereof, the slot 11 extends from outside to inside along the axial direction, and the slot 11 is square. The containing cylinder 1 is provided with three through holes 12 along the radial direction, and the three through holes 12 are uniformly arranged along the axial direction of the containing cylinder 1 at intervals. Every perforation 12 all is equipped with lock row 2, and every lock row 2 all corresponds slot 11 and is equipped with hollow portion, all is equipped with first elastic component 3 between every lock row 2 and the holding cylinder 1. The outer end of the containing barrel 1, namely the end of the containing barrel 1 close to the opening of the slot 11, is provided with an anti-theft head 4, and the anti-theft head 4 is clamped with the containing barrel 1. The anti-theft head 4 is provided with a socket 41 aligned with the slot 11, an anti-theft block 5 is arranged between the anti-theft head 4 and the accommodating barrel 1, the anti-theft block 5 can move along the radial direction of the accommodating barrel 1, and a second elastic part 6 is arranged between the anti-theft block 5 and the anti-theft head 4. When the lock cylinder mechanism is applied to a lockset, the lock shell is sleeved outside the containing barrel 1 of the lock cylinder mechanism. When the lock core mechanism is in a locking state, one end of the anti-theft block 5 protrudes out and is blocked in the inserting hole 41, the three lock rows 2 are clamped between the accommodating cylinder 1 and a lock shell of a lock to realize locking, and the accommodating cylinder 1 cannot rotate relative to the lock shell; combine shown in fig. 3, when unblanking through the unblock key 7 with this lock core mechanism assorted, unblock key 7 promotes the theftproof piece 5 when inserting socket 41 and keeps away from socket 41 and removes, second elastic component 6 produces elastic deformation, unblock key 7 continues to insert to slot 11, unblock key 7 promotes makes three lock row 2 all remove to the edge of holding a section of thick bamboo 1 and lock shell handing-over, realize the unblock of this lock core mechanism, can drive through unblock key 7 and hold a section of thick bamboo 1 relative lock shell rotation and then realize the unblock of tool to lock. Through the arrangement of the anti-theft block 5, when the lock cylinder mechanism is in a locking state, the anti-theft block 5 blocks the socket 41, so that the gap between the socket 41 and the opening of the slot 11 becomes very narrow, and a theft tool cannot be inserted, therefore, the locking effect is good, and the anti-theft performance is obviously improved.
As shown in fig. 2 and 3, as an optimization, the anti-theft block 5 is provided with an auxiliary inclined surface 51 for assisting the unlocking key 7 to push the anti-theft block 5 to move away from the socket 41, and the anti-theft block 5 can be pushed to move more conveniently through the auxiliary inclined surface 51.
