In a state where the bolt member 110 is in the locked position and the key 130 is not inserted into the key slot 121, the key cylinder member 160 is in the limit position to block the transmission 150 from moving in the first direction D1, thereby preventing the bolt member 110 from moving from the locked position to the open position and preventing the anti-theft lock 100 from being unlocked or damaged by force.

In a state where the latch member 110 is in the locking position and the key 130 is inserted into the key slot 121, the second magnet 162 and the first magnet 131 can magnetically attract each other, so that the key cylinder member 160 is maintained at the guide position to allow the transfer 150 to move in the first direction D1, so that the latch member 110 can move from the locking position to the opening position. Therefore, the security of the anti-theft lock 100 of the present invention is high, and is not easily copied or damaged, and does not protrude out of the outer surface of the case 10, so that it is more beautiful.

In this embodiment, the keeper member 110 is movable between a locked position and an open position along a second direction D2, the second direction D2 being different from the first direction D1. Preferably, the second direction D2 is perpendicular to the first direction D1. Fig. 2 exemplarily shows that the first direction D1 is a horizontal direction and the second direction D2 is a vertical direction. It will be appreciated by those skilled in the art that the second direction D2 may not be perpendicular to the first direction D1, the first direction D1 may be at an angle to the horizontal direction, and the second direction D2 may be at an angle to the vertical direction, as desired.

As shown in fig. 2 and 3, the antitheft lock 100 includes a plurality of cylinder members 160, and the plurality of cylinder members 160 are spaced apart in the second direction D2. Preferably, the spacing between the second magnets 162 of two adjacent latch core members 160 in the plurality of latch core members 160 along the second direction D2 is not exactly the same, and the projections of the second magnets 162 of the plurality of latch core members 160 on the same plane (e.g., the same horizontal plane) perpendicular to the second direction D2 do not exactly overlap.

The key 130 is correspondingly provided with a plurality of first magnets 131, and the number of the plurality of first magnets 131 is the same as the number of the second magnets 162 of the plurality of key cylinder members 160. In a state where the key 130 is inserted into the key slot 121, the positions of the plurality of first magnets 131 correspond to the positions of the second magnets 162 of the plurality of key cylinder members 160 one by one, and the relative magnetic poles of the first magnets 131 and the second magnets 162 corresponding thereto are opposite in polarity. Because the positions of the plurality of key cylinder members 160 are different, and the polarities of the ends, corresponding to the first magnet 131, of the second magnets 162 of the plurality of key cylinder members 160 can be randomly arranged, the design of the anti-theft lock 100 has a plurality of combinations, and therefore the anti-theft lock has high safety and is not easy to copy or crack.
