[0024] The four-lock linkage mechanism includes a first fixed plate, a gear, four toothed rods and four connecting locking members. The first fixed plate has two pieces, one of which is fixed on the cabinet door. The gear is arranged in the middle of the first fixed plate. One end of each toothed rod is provided with a rack matching the gear. The other end of each toothed rod is connected to the connecting locking member. The rotation of the gear can drive the toothed rod to slide, thereby driving the connecting locking member to move. The connecting locking member can lock or release the cabinet door away from one end of the toothed rod. Another first fixed plate covers the outside of the four toothed rods. A gap is left between the two first fixed plates for the four toothed rods to slide. Each toothed rod is provided with a first The guide groove, the first fixing plate is also provided with a first positioning pin, the first positioning pin is embedded in the first guide groove, so that when the gear is rotated, the gear rod will be limited and can only move along the path set by the first guide groove. This specific embodiment is to limit the four gear rods to move in four directions of up, down, left and right respectively, and a second guide groove is also provided on the connecting locking member, and a second positioning pin is provided on the cabinet door, and the second positioning pin is embedded in the second guide groove, so that the connecting locking member can only move along the path set by the second guide groove. This specific embodiment is to limit the four connecting locking members to move in four directions of up, down, left and right respectively;

[0025] And the four gear rods are divided into two groups, the first group is the gear rods moving left and right, the second group is the gear rods moving up and down, and the first group and the second group are respectively arranged on two layers. In this specific embodiment, the second group is arranged on the lower layer, and the first group is arranged on the upper layer. Moreover, each gear rod includes a front part, a middle part and a rear part. The front part is provided with a rack to cooperate with the gear. For example, the front part of the gear rod moving left in the first group is arranged above the gear, the front part of the gear rod moving right in the first group is arranged below the gear, the front part of the gear rod moving up in the second group is arranged on the right side of the gear, and the front part of the gear rod moving down in the second group is arranged on the left side of the gear. This is arranged according to needs, and can be interchanged as long as there is no conflict. The middle part of each gear rod is provided with a first guide groove, and this part cooperates with the first positioning pin on the first fixing plate. The rear part of each gear rod is connected to a locking member for locking the cabinet.

[0026] A mechanical handle is provided on the other side of the cabinet door 1, and the mechanical handle is fixed to the gear, so that when the mechanical handle is turned, the gear will rotate together, and then the gear will move with the four gear rods, that is, the four gear rods move up, down, left and right respectively, and the gear rods will drive the connecting locking parts connected to the gear rods to move. After moving a certain distance, the cabinet door can be locked, and the cabinet door can be opened by turning the mechanical handle in the opposite direction;

[0027] The first lock 6 is a fingerprint and facial recognition lock in this specific embodiment, including a lock disk with a fingerprint input part and a facial recognition part and a lock box with a lock tongue. The lock disk and the lock box are connected by a wire harness, so that the user can press the fingerprint input part to input a fingerprint, or stand in front of the facial recognition part to input facial information to control the extension and retraction of the lock tongue of the lock box. This lock is available on the market in the prior art, so this specific embodiment will not be elaborated in detail again;

[0028] In this specific embodiment, a limit block is provided on one of the connecting locking members, and the limit block is fixed on the connecting locking member, so that the limit block and the connecting locking member are integrated, and a notch is provided at the locking end of the limit block, and the lock tongue of the first lock can be embedded in the notch, so that when the cabinet door needs to be locked, the first lock will control the lock tongue to extend and embed into the notch of the limit block, so that the limit block cannot move vertically, thereby causing the connecting locking member to also not move vertically, thereby realizing the locking of the cabinet door; when the cabinet door needs to be opened, the lock tongue of the first lock is controlled to retract, so that the limit block is not limited by the lock tongue of the first lock and can move automatically, thereby making it possible to control the mechanical handle to rotate, drive the gear to rotate, and then control the four gear rods to move, thereby driving the four connecting locking members to move, thereby realizing the opening of the cabinet door.
