When the lock core with the structure is used, the limiting component 40 and the locking component 50 are arranged, so that the limiting component 40 and the locking component 50 can act on the locking component 30 together, the lock core can be unlocked only after the limiting component 40 and the locking component 50 are unlocked completely, and the safety of the lock core is effectively improved.

In addition, in the present application, when the limiting assembly 40 is located at the limiting position, the limiting assembly 40 can limit the locking assembly 30, that is, after the locking assembly 50 releases the locking of the locking assembly 30, the locking assembly 30 cannot be switched from the locking position to the unlocking position. The locking assembly 30 can be switched from the locked position to the unlocked position only after the limiting assembly 40 is switched from the limiting position to the avoiding position and simultaneously the locking assembly 50 is switched from the stopping state to the avoiding state to unlock the locking assembly 30. And, after locking subassembly 30 switches to the unblock position, locking subassembly 30 can carry out the joint with spacing subassembly 40 to make spacing subassembly 40 keep in the position of stepping down, only after locking subassembly 30 switches to the shutting position by the unblock position, locking subassembly 30 just can remove the joint with spacing subassembly 40, and spacing subassembly 40 can just switch to the spacing position by the position of stepping down this moment.

With such an arrangement, when the lock assembly 30 is switched from the locked position to the unlocked position after the limiting assembly 40 and the locking assembly 50 release the limiting on the lock assembly 30, the lock cylinder 20 can be driven by the key to rotate, so that the parts of the first locking piece 31 and the second locking piece 32 extending into the locking groove 11 can be withdrawn from the locking groove 11 under the action of the guide inclined surface 34, and the lock assembly 30 is switched to the unlocked position, so that the unlocking of the lock cylinder can be completed. In addition, when the lock cylinder is locked, the first locking piece 31 and the second locking piece 32 can be more smoothly extended into the locking groove 11, and the stability of the lock cylinder can be effectively ensured.

As shown in fig. 1, 3 and 12, a side of the first locking member 31 close to the authorization pin 41 has a protruding portion 311, and when the limiting assembly 40 is switched from the limiting position to the yielding position, at least a portion of the protruding portion 311 can extend into the yielding groove 411. With such an arrangement, it can be effectively ensured that the limiting component 40 can limit the locking component 30 by limiting the protruding part 311.
