The invention relates to an anti-theft lock locking head with a secondary locking structure. The anti-theft lock locking head comprises a shell, a lock core, a main unlocking piece and an auxiliary unlocking piece; a main groove and auxiliary grooves are formed in the inner wall of the shell; a plurality of blades are arranged in the lock core, and the lock core is provided with a first key grooveand second key grooves; each blade is provided with a main slot, an auxiliary slot and a restriction groove; the main unlocking piece is provided with an internal clamp key and an external clamp key;in a locking state, the external clamp key is located in the main groove, while the internal clamp key is located in the first key groove, the auxiliary unlocking piece is located in the auxiliary grooves and the second key grooves at the same time, and the lock core is connected with the shell; during unlocking, the auxiliary unlocking piece first breaks away from the shell and falls into the auxiliary slot, and then the internal clamp key is pushed into the main slot; when a master key or other tools are used for abnormal unlocking, the external clamp key stays in the main groove while theinternal clamp key completely falls into the first key groove, and the lock core and the shell can rotate opposite to each other to be in an idling state. The anti-theft lock locking head has the advantages of idling function, stronger anti-theft performance and is suitable for small size.
本发明涉及具有二级锁定结构的防盗锁锁头，其包括外壳、锁芯、主开锁件和副开锁件；外壳内壁上设置主沟槽和辅沟槽；在锁芯内排列若干个叶片，锁芯设有第一键槽和第二键槽；每片叶片有主凹槽、辅凹槽和制约槽；主开锁件具有内卡健和外卡键；锁定状态下，外卡键处于主沟槽而内卡健处于第一键槽中，副开锁件则同时处于辅沟槽和第二键槽，锁芯与外壳相连接；开锁时，副开锁件先脱离外壳落入辅凹槽中后，内卡健顶入主凹槽中；使用万能钥匙或其他工具进行非正常开锁时，外卡键滞留在主沟槽中而内卡健完全落在第一键槽中，锁芯与外壳能相对转动而呈空转状态。本发明的优点在于具有空转功能、更强防盗性能,并且适用于小体积。
