Abstract
A cabinet lock includes a lock shell, a lock frame and a restricting device. The lock shell defines a card insertion space, the lock frame includes a slide portion, a hasp portion, an initiative portion and a core, the hasp portion defines a slide groove, the initiative portion is fixed to the hasp portion within the slide groove. The core extends into the main shell to contact with the hasp portion. A block and a protruding portion are defined where the lock block moves away from the stop portion by an external force displacing the extruding portion. Thus, the key can be removed from the core when the card is inserted, and the block locks the card and does not permit removal of the card. The card can be removed when the key is inserted into the core which avoids the loss of the card and the key together.
