The invention relates to a lock head, in particular to a mortise lock. The lock head comprises a lock body, a lock cylinder located in the lock body, an inner marble located in a marble channel of the lock cylinder and provided with a password notch, and a code distinguishing piece located in a code distinguishing piece channel of the lock cylinder. The lock head is characterized in that a control slide block which is driven by a key and can directly control the code distinguishing piece and an anti-shifting piece to move back and forth through a front control inclined surface and a rear control inclined surface is arranged; and the back surface of the inner marble is also provided with anti-shifting teeth/misleading ratchets. According to the lock head, the capability of preventing technical unlocking and forced unlocking of a lock is further improved. Through further improvement, a non-rotating lock cylinder capable of giving an unlocking signal to a lock as long as a key is inserted can also be created.
本实发明涉及一种锁头，更确切地讲涉及一种插芯锁。包括锁体、位于锁体中的锁芯、位于锁芯的弹子通道中并设有密码缺口的内弹子、位于锁芯的辨码片通道中的辨码片。本发明的要点就是：设有由钥匙驱动的，可直接通过其前后两个控制斜面，来控制辨码片和防拨片前后移动的控制滑块；其内弹子的背面还设有防拨齿/误导棘齿。本发明将使锁具的防技术开启和防强行开启的能力进一步提高。通过进一步改进，还可以创造出一种只要插入钥匙就可以给锁具一个开启信号的不转锁芯。
