Lock core
The lock cylinder comprises a cylinder head, a lock cylinder sleeve, a locking piece, a positioning ring and a limiting mechanism, the cylinder head is sleeved with the lock cylinder sleeve, the locking piece is movably clamped in the cylinder head in parallel, the positioning ring is sleeved with the top of the lock cylinder sleeve, and the limiting mechanism abuts against and limits rotation of the lock cylinder sleeve. A plurality of groups of sheet-shaped locking sheets are adopted to replace a safety pin, and unlocking can be realized only when the locking sheets are clamped into all the clamping grooves in the lock cylinder body, so that code groups are increased, and the safety is improved; a lock cylinder needs to be subjected to dislocation operation through a constraint structure of rotation of a locking piece and a cylinder body, an unlocking step is added, the unlocking process is changed into a composite multi-degree-of-freedom action from a single-degree-of-freedom action and is more complex, then the difficulty of non-key unlocking is increased, and safety is improved; the shoulder is arranged on the front portion of the core head, the front end of the lock cylinder sleeve is clamped through the shoulder, so that the core head is exposed out of the lock cylinder sleeve to form the convex core head and the key hole, the core head and the key hole can be arranged from the front end of the prefabricated key hole, installation is convenient, a decorative ring is omitted, and simplicity is achieved.
本发明公开了一种锁具芯，包括芯头、锁芯套、锁定片、定位环和限位机构，芯头套接在锁芯套中，锁定片平行活动卡接于芯头内，定位环套接在锁芯套顶部，限位机构抵接限制锁芯套转动。采用多组片状的锁定片代替保险针，同时需要卡入锁芯体内所有的卡槽中才能脱锁，增加了密码组，从而增加了安全性；通过锁定片及芯体旋转的约束结构需要对锁芯进行错动操作，增加解锁步骤，使得解锁过程从单一自由度动作变为复合多自由度动作，更复杂，进而增加非钥匙解锁的难度，提高安全性；芯头前部设置有台肩，通过台肩卡接锁芯套的前端，使得芯头露出于锁芯套形成外凸的芯头及钥匙孔，可以从预制钥匙孔前端置入，方便安装，取消了装饰环，更具简洁性。
