Abstract

A magnetic anti-theft lock and its key mainly comprise a lock sleeve, a lock pin, upper marbles, lower marbles, marble hole bottom magnets, a key and a key magnet. The lock pin is rotatably assembled in the lock sleeve. The same corresponding sides of the lock pin and the lock sleeve are provided with at least two through holes, which are successively filled with the upper marbles, the lower marbles and the marble hole bottom magnets. The upper surface of the assembled upper marbles is lower than the lower surface of key holes. The upper marbles are prepared from a magnetic material. The lower marbles are prepared from a magnetic conductive material. The upper marbles attract the lower marbles to form marble groups. The length of the lower marble of each marble group is the same, but the length of the upper marble is different. The sum of the upper marble's height and the lower marble's height is greater than the distance from the lower interface of the lock pin and the lock sleeve to the upper surface of the key holes. When unlocking, a tooth-shaped key with magnets attracts each marble group and cooperates with each marble group for unlocking. The marbles provided by the utility model is concealed in the lock pin that a master key can not push aside, thereby effectively preventing the master key from unlocking. The utility model is suitable for being applied in magnetic locksets.
