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.
Description
Technical field
The present invention relates to a kind of door lock, specifically is a kind of door lock of clamshell doors refrigerator.
Background technology
Existing clamshell doors type refrigerator is provided with door lock, and this door lock is used to open or two refrigerator doors that split around of closing refrigerator.
The weak point of this Door lock of refrigerator is: open when this door lock only can be realized two refrigerator doors or closing control, on one side and the control that another side is closed when can not realize two refrigerator doors are opened.
Summary of the invention
First technical problem that the present invention solves provides a kind of door lock, the control operation that another side is closed when making two refrigerator doors of the clamshell doors refrigerator that this door lock is installed realize opening on one side.
Second technical problem that the present invention solves provides a kind of clamshell doors refrigerator with above-mentioned door lock.
For solving above-mentioned first technical problem, the technical solution used in the present invention is:
A kind of door lock, comprise lock box, be arranged on the key rotating shaft in the lock box, and be connected with the key rotating shaft and be located in two lock shaft cores in the lock box shell, it is characterized in that: this door lock also comprises: be installed in the rotating disk in the key rotating shaft, and and two lock shaft cores form two first connecting rods of two cover latch mechanisms, two second connecting rods, two third connecting rods, in a cover latch mechanism, first connecting rod, one end of second connecting rod and third connecting rod is hinged jointly, and the other end and the rotating disk of first connecting rod are hinged, the other end and the lock box of second connecting rod are hinged, and an end of the other end of third connecting rod and lock shaft core is hinged.
As one of improvement of the present invention: this door lock also comprises two shaft locking sleeves that are used to be arranged on the refrigerator doors, respectively is provided with on this two shaft locking sleeve and the corresponding lockhole of described two lock shaft cores.
For solving above-mentioned second technical problem, the technical solution used in the present invention is:
A kind of clamshell doors refrigerator, comprise refrigerator main body, two refrigerator doors is characterized in that: described refrigerator main body is provided with the lock box as first technical scheme or the described door lock of its improvement project, and also is respectively equipped with the two corresponding shaft locking sleeves of two lock shaft cores in the lock box with this door lock on described two refrigerator doors.
Compared with prior art, the beneficial effect of first technical scheme is: by bar linkage structure cleverly, make this door lock can control the operation that two refrigerator doors are closed successively simultaneously, another side is closed while opening, both sides are closed simultaneously and the another side unlatching is closed, realized independent open and close controlling two refrigerator doors.
Compared with prior art, the beneficial effect of second technical scheme is: because above-mentioned door lock is installed, so two refrigerator doors of this refrigerator can realize independent open and close controlling.
