Abstract
A magnetic lock includes a first metal block securely received in the first frame, and an electrical magnet adapted to connect to a power source to selectively become a magnet and a second frame adapted to be mounted on a door and provided with a second metal block movable respect to the first metal block and the second frame. The second metal block has two retaining recesses to respectively receive therein two clamping blocks. Each of the two clamping blocks is adapted to be movably received in the two retaining recesses and has a recess to receive therein one of the two bolts. When the second metal block is moved by an external force, an inner side face of the recess of each of the clamping blocks abuts a side face of each of the bolts so that the door is still secured to the doorframe.
