The invention discloses a magnetic door lock. A first magnet is arranged in a lower locking dog groove in an embedded mode, a cylindrical body of a first square hole is arranged in a chamber body, a connecting plate is connected with a pushing rod, the pushing rod is connected with a lower locking dog, a second magnet is arranged in the lower locking dog in an embedded mode, the lower locking dogextends out of a lower locking dog opening to be matched with the lower locking dog groove, and a second protrusion is used for abutting against the connecting plate; a shifting rod is further hingedto the cylindrical body, and a protruding tongue is arranged on the shifting rod in an extending mode and used for abutting against the connecting plate; and a second track column is provided with a coil spring, a third track of an upper pushing plate is matched with a first track column, the upper pushing plate is connected with the left portion of an upper locking dog, a third track column is arranged in the middle of the upper pushing plate, a fourth track on the upper portion of a tongue pushing plate is matched with the third track column, the lower end of the tongue pushing plate and a small hole of the shifting rod are hinged, a second cylindrical body is provided with a torsion spring, an engaged part is matched with an opening of the upper pushing plate, a lock cylinder is screwed, thus the engaged part shifts the upper pushing plate to move leftwards and rightwards, and the first square hole is provided with a square rod handle. The magnetic door lock is simple in structure and high in reliability, the lower locking dog is locked through attraction of the magnets, and thus reliability of locking is further ensured.
