In the embodiment of the invention, the opening and locking of the magnetic door lock can be realized through the magnetic action between the magnet key 1 and the key cylinder magnet 4. Under the locking state, under the action of the elastic force of the spring 5, one end of the limiting sleeve 3 is in contact with the lock base body 21, the inner side of the other end of the limiting sleeve 3 is in contact with the limiting baffle 62, and the boss 31 at the other end of the limiting sleeve is in contact with the lock base spring plate 22, so that the limiting protrusion 221 of the lock base spring plate 22 is inserted into and limited in the limiting groove 711, and the locking of the magnetic door lock is realized.
Specifically, when locking the door, on the premise that the magnet key 1 and the cylinder magnet 4 are homopolar and opposite, the magnet key 1 is used to be close to the cylinder assembly. Because like-polarity repulsion of the magnets, magnetic force can push the lock core magnet 4 to move backwards, the lock core magnet 4 can drive the limiting sleeve 3 to move outwards along the lock base shaft 23, namely move backwards relative to the lock base body, and at the moment, the boss 31 of the limiting sleeve can be staggered with the limiting protrusion 221 of the lock base reed.

At this time, if the door is attempted to be opened, the relative movement between the lock sleeve 71 and the lock housing spring 22 presses and inwardly compresses the stopper projection 221 of the lock housing spring, but the projection 31 of the stopper sleeve prevents the deformation of the stopper projection 221, so that the stopper projection 221 is still inserted into the stopper groove 711, thereby blocking the relative movement between the lock sleeve 71 and the lock housing spring 22 and preventing the door opening operation.
When the door is opened, on the premise that the magnet key 1 and the lock cylinder magnet 4 are opposite in homopolar, the magnet key 1 is close to the lock cylinder magnet 4 for unlocking. When magnet key 1 was close to lock core magnet 4, lock core magnet 4 drove stop collar 3 and outwards removed, and boss 31 of stop collar 3 and the spacing arch of lock seat reed stagger this moment, as shown in fig. 3, if open the chamber door this moment, can make lock core subassembly break away from in the lock sleeve, realize opening the door. After the door is opened, the magnet key 1 is removed.
