Description

Technical Field

[0001] The invention relates to the technical field of lock accessories, in particular to a lock core protection structure and a lock core. Background Art

[0002] Existing locks generally include a lock, a lock core, and a lock shell. The principle is that after a matching key is inserted into the lock, the lock can rotate in the lock shell. The lock shell is embedded in the lock core, and the lock shell and the lock core are locked by one or more pins to prevent them from falling off.

[0003] The lock core is the core component of the lock. Its principle is to open and close the lock by accurately matching the key with the mechanical structure inside the lock core. The interior of the lock core usually contains multiple marbles (or pins) and spring components, which are precisely arranged to form a safety barrier for the lock. When the correct key is inserted into the lock core, the teeth on the key and the position of the marbles inside the lock core are completely consistent, so that the marbles all fall into the corresponding grooves under the action of the spring. In this way, the lock core can rotate smoothly, and then the linkage mechanism controls the extension and retraction of the lock bolt (or lock tongue) to complete the opening and closing of the door.

[0004] A Chinese patent with a publication (announcement) number of CN117588110A discloses a lock core, which includes a main body, a key core is provided at one end of the main body, a thumb turner is provided at the other end of the main body, an elongated movable groove along its length direction is opened on the main body, and a first threaded hole is also provided on the main body, the first threaded hole is connected to the elongated movable groove and is offset from the midpoint of the length of the elongated movable groove; linear slide rails are provided on both side walls of the elongated movable groove along its length direction, an elongated movable part is movably connected in the elongated movable groove through the linear slide rails, the length of the elongated movable part is less than the length of the elongated movable groove, springs are provided at both ends of the elongated movable part and between the two side walls of the elongated movable groove along its width direction, a second threaded hole is provided on the elongated movable part, and the second threaded hole is offset from the first threaded hole when the spring is in a natural state.
