The lock core in the application comprises a lock shell 10, a lock cylinder 20, a locking assembly 30, a limiting assembly 40 and a blade locking assembly 50. The inner side wall of the lock case 10 is provided with a locking groove 11; at least one part of the lock core 20 extends into the lock shell 10, and the lock core 20 can rotate relative to the lock shell 10; the locking component 30 is embedded in the lock core 20 and arranged along the length direction of the lock core 20, the locking component 30 can extend into the locking groove 11 from the lock core 20 to lock the lock core 20, and the locking component 30 has a locking position and an unlocking position; the limiting component 40 is movably arranged inside the lock core 20 along the radial direction of the lock core 20 and limits the locking component 30, and the limiting component 40 is provided with a limiting position and a yielding position so that the locking component 30 can be switched between a locking position and an unlocking position; the blade locking assembly 50 is arranged between the lock core 20 and the lock shell 10, at least one part of the blade locking assembly 50 penetrates through the locking assembly 30, when the blade locking assembly 50 releases the locking of the locking assembly 30 and the limiting assembly 40 is located at the abdicating position, the limiting assembly 40 releases the limiting of the locking assembly 30, and the locking assembly 30 can move towards the inside of the lock core 20 and is switched from the locking position to the unlocking position; when the lock cylinder is in a locking state, the limiting component 40 is in a limiting position, the limiting component 40 and the blade locking component 50 enable at least one part of the locking component 30 to be located in the locking groove 11, the locking component 30 is in a locking position, and the lock core 20 and the lock shell 10 are kept locked; when the lock cylinder is unlocked by using the unlocking key 60, the unlocking key 60 drives the blade locking assembly 50 to rotate, the blade locking assembly 50 releases the limit of the locking assembly 30, the limiting assembly 40 senses the unlocking key 60 and is switched to the abdicating position from the limiting position, the locking assembly 30 can exit the locking groove 11, so that the locking assembly 30 is switched to the unlocking position from the locking position and is clamped with the limiting assembly 40, the limiting assembly 40 is kept at the abdicating position, the lock cylinder is switched to the unlocking state from the locking state, and the lock cylinder 20 can rotate relative to the lock shell 10.

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

In addition, in the present application, when the position limiting assembly 40 is located at the position limiting position, the position limiting assembly 40 can limit the position of the locking assembly 30, that is, even after the blade 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 yield position and at the same time the blade blocking assembly 50 releases the lock on 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.

Specifically, at least a portion of the limiting assembly 40 moves in the radial direction of the lock case 10 to limit the locking assembly 30.
