The anti-theft lock comprises a lock cylinder, a lock cylinder shell, a shielding block and the like, the lock cylinder is inserted into the lock cylinder shell, a groove hole is formed in the lock cylinder, the shielding block is located in the groove hole, and a first groove is formed in the lock cylinder shell; when one end of the shielding block is aligned with the first groove, the shielding block can move towards the first groove, the shielding block can be inserted into the first groove and/or the key hole, when the shielding block moves towards the key hole, a key hole channel is shrunk or closed, and on the contrary, when the shielding block moves towards the first groove, the key hole becomes large. Meanwhile, the shielding block can protrude out of the lock cylinder to clamp the lock cylinder and the lock cylinder shell, and unlocking cannot be achieved, so that the shielding block must be inserted into the key hole to close a key hole channel during unlocking; in this way, lawbreakers can be prevented from inserting unmatched unlocking tools such as iron wires and flat iron needles into the key hole to move parts in the key hole to try to unlock the lock, and therefore the technical unlocking prevention capacity is greatly improved.
本发明提出了一种防盗锁，包括锁芯、锁芯外壳、遮挡块、等部件，锁芯插入锁芯外壳中，锁芯设置有槽孔，遮挡块位于槽孔中，锁芯外壳设置有第一凹槽；遮挡块一端对准第一凹槽时，遮挡块可以往第一凹槽移动，移动遮挡块可以插进第一凹槽和/或钥匙孔中，遮挡块往钥匙孔方向移动时钥匙孔通道将缩小或关闭，相反，遮挡块往第一凹槽方向移动时钥匙孔将变大，同时遮挡块会凸出锁芯将锁芯和锁芯外壳卡住不能开锁，因此开锁时，遮挡块必须插入钥匙孔中将钥匙孔通道关闭才能开锁，由此可以阻止不法分子用铁丝、扁铁针等不匹配的开锁工具插入钥匙孔内部进行移动钥匙孔内部零件尝试把锁打开，因此本发明大大的提高了防技术开启的能力。
