Abstract

The invention relates to a door lock, in particular to a door lock for an opposite-door refrigerator. The door lock comprises a lock box, a key rotating shaft arranged in the lock box and two lock shaft cores connected with the key rotating shaft and arranged in the casing of the lock box in a penetrating way. The door lock is characterized in that the door lock also comprises a rotating disk fixedly arranged on the key rotating shaft, and two first connecting rods, two second connecting rods and two third connecting rods which form two sets of lock mechanisms with the two lock shaft cores; in one of the two sets of lock mechanisms, one end of the first connecting rod, the second connecting rod and the third connecting rod is articulated together, the other end of the first connecting rod is articulated with the rotating disk, the other end of the second connecting rod is articulated with the lock box, and the other end of the third connecting rod is articulated with one end of the lock shaft core. Through the ingenious connecting rod structure, the operations of simultaneously closing the two doors in sequence, opening one door and closing the other door, simultaneously closing the two doors, and opening the other door while closing one door can be controlled through the door lock, thereby realizing separate opening and closing control to the two refrigerator doors. Besides, the invention also discloses an opposite-door refrigerator provided with the door lock.
