[0039] The door magnet 3 is mainly composed of a coil (not shown), an iron core (not shown), a flat plate 32 and a latch 31. The iron core and the latch 31 are generally made of soft magnetic materials. The iron core is stationary and the coil is installed on the iron core. When the coil in the door magnet 3 is energized, the latch 31 and the iron core are magnetized, and they directly generate electromagnetic attraction to attract each other.

[0040] The two working schemes of the embodiment of the utility model are:

[0041] The first solution is to open the cabinet door 11 by twisting the lock cylinder 2 with a key and pulling the door handle 5:

[0042] The user inserts the key into the lock cylinder 2, twists the key counterclockwise 90 degrees to drive the door magnet switch lock plate 1 to rotate together, when the door magnet switch lock plate 1 is close to the door magnet 3, the flat plate 32 is pushed into the door magnet 3, and the latch 31 is driven to slide into the door magnet 3. At this time, the limit plate 4 is in a movable state, and the user rotates the door handle 5 90 degrees clockwise. The rotation of the door handle 5 drives the eccentric guide shaft 9 to slide and connect with the limit plate 4, thereby driving the limit plate 4 to move along the direction of the horizontal guide assembly 17. At the same time, the limit plate 4 drives the door lock mechanism 7 and the lock head 8 to move to the right to leave the cabinet 10 on the left, and the cabinet door 11 can be opened.

[0043] Furthermore, after the coil in the door magnet 3 is energized, the iron core has suction force. When the door magnet switch lock plate 1 is close to the door magnet 3 and the flat plate 32 is pushed into the door magnet 3, the latch 31 is driven to slide into the door magnet 3. At this time, the iron core in the door magnet 3 uses suction force to attract the latch 31, so that the latch 31 can be slid into the door magnet 3, thereby making the limit plate 4 movable.

[0044] The second solution is to open the cabinet door 11 by entering a password:

[0045] A circuit board (not shown) is provided in the password panel 13 to supply power to the coil in the door magnet 3. After the user enters a preset password in the password panel 13, the coil in the door magnet 3 is energized, and the iron core generates suction to attract the latch 31 to the iron core in the door magnet 3. At this time, the limit plate 4 is in an active state. The user then rotates the door handle 5 90 degrees clockwise. The rotation of the door handle 5 drives the eccentric guide shaft 9 to slide and connect with the limit plate 4, thereby driving the limit plate 4 to move in the direction of the horizontal guide assembly 17. At the same time, the limit plate 4 drives the door lock mechanism 7 and the lock head 8 to move to the right to leave the cabinet 10 on the left, and the cabinet door 11 can be opened.

[0046] The password panel 13 and the door magnet switch lock piece 1 act together on the door magnet 3 to limit the movement of the limit plate 4. The cabinet door swing door lock has a simple structure and low production cost. The key opening mode and the password input mode are easily switched and the operation is convenient.

[0047] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
