At least three sets of side lock cylinders are evenly arranged circumferentially around the drive motor. Locking pins are rotatably arranged on the side lock cylinders. After at least two of the locking pins contact the trigger ring, the controller controls the drive motor to work, thereby driving the pins to slide away from the cabinet.

[0009] The power supply mechanism is mounted on the lock box and is connected to the controller via a wiring harness.

[0010] In one embodiment of this utility model, a latch mounting groove is provided on the outer side of the cabinet door. The latch assembly also includes a guide rail disposed in the latch mounting groove and a rack slidably disposed in the guide rail. One end of the rack is connected to the latch. A drive gear is provided on the output shaft of the drive motor, and the drive gear meshes with the rack.

[0011] In one embodiment of this utility model, a pin through hole is provided on the frame of the cabinet door, which is connected to the pin mounting groove. A pin hole is provided on the frame of the cabinet door corresponding to the pin through hole, and the pin is inserted into the pin hole after passing through the pin through hole.

The lock box is fixed to the cabinet door by inserting a long bolt through the inside of the cabinet door.

[0013] In one embodiment of this utility model, the trigger ring is circular in shape, with a trigger ring through hole in its center that matches the cross-sectional profile of the drive motor. Several mounting grooves are provided on the outer edge of the trigger ring corresponding to the movement trajectory of the locking pin. A push switch is provided in the mounting groove. The push switch is connected to the controller via a wiring harness. The locking pin is rotated to press the push switch so that the controller receives a trigger signal.

[0014] In one embodiment of this utility model, a trigger ring threaded hole is provided in the mounting groove, which communicates with the trigger ring through hole. A set screw is rotatably provided in the trigger ring threaded hole. A positioning hole is provided on the drive motor corresponding to the set screw. Tightening the set screw causes the set screw to enter the positioning hole to fix the trigger ring on the drive motor.

[0015] As one embodiment of this utility model, the lock box is provided with a plurality of lock cylinder cavities arranged in a circular array on the side facing the cabinet door, and the shape and size of the lock cylinder cavities are adapted to the shape and size of the side post lock cylinder;

[0016] A pressure plate mounting groove is provided at the end of the lock cylinder cavity. A pressure plate is detachably mounted on the pressure plate mounting groove by means of a screw assembly. The pressure plate abuts against the side post lock cylinder to press and fix the side post lock cylinder in the lock cylinder cavity.

[0017] In one embodiment of this utility model, the edge of the accommodating cavity is provided with a locking pin relief groove corresponding to the locking pin. The locking pin relief groove is connected to the lock cylinder cavity, and the locking pin rotates through the locking pin relief groove to abut against the trigger ring.

The touch screen is connected to the controller via a wiring harness. The touch screen is used to display the number of times the lock is opened and to input instructions to drive the latch into the cabinet.

[0020] The beneficial effects of adopting the above technical solution are as follows:

[0021] This application's lockbox features multiple side-pin lock cylinders. Inserting any two keys and rotating them triggers the trigger ring twice within a short time, causing the controller to rotate the drive motor, moving the bolt away from the cabinet and unlocking it. In practical applications, taking a three-pin lock cylinder as an example, with three people each holding one key, unlocking is possible with just two keys. If one person leaves due to unforeseen circumstances and cannot hand over the keys, the remaining two can still open the cabinet. This design also overcomes the problem of delayed unlocking caused by the inability of one person to arrive quickly enough in emergency situations like retrieving medication. In summary, compared to structures requiring only two keys for unlocking, this application significantly increases the flexibility of unlocking. Attached Figure Description
