Abstract

The present invention discloses a lock core with an alarm, which is mainly provided with a casing, an inner rotating body, a plurality of lock pin groups, an alarm triggering group and an alarm removing group. When in use, a correct key is inserted into a key plughole of the inner rotating body, the wall surface of the key upwards pushes the alarm triggering group, a lock column of the alarm triggering group contacts an alarm triggering switch arranged in an insulating stool, and the alarm triggering switch activates an alarm arranged in a lockset; after the key of a user is inserted into the lock to upwards push and trip the lock pin groups, the inner rotating body is rotated, a lock column of the alarm removing group is upwards pushed by the wall surface of the inner rotating body, the lock column contacts an alarm removing switch arranged in the insulating stool to remove the alarm of the alarm, and then, the action of unlocking can be completed by the method. If thieves uses a correct key which is not matched with the lockset or other unlocking tools to extend to the key plughole, the alarm can be activated; if the inner rotating body is rotated without the time set by the alarm to enable the lock column of the alarm removing group to contact the alarm removing switch, and the alarm can be alarmed to scare the thieves. The present invention has the optimal efficiency of theft prevention.
