Description
Technical Field
The invention relates to a refrigerator, in particular to a support and door lock device for a refrigerator door.
Background
The refrigerator door supporting and locking device of the invention is similar to a refrigerator. In household appliances such as refrigerators and the like, locks are required to prevent children from opening the doors, and the locks generally have the characteristics that the size is small, and a plurality of locks can be opened by one key. The refrigerator or freezer door lock comprises a lock head, a lock cylinder and a lock tongue, wherein a limiting clamping groove is formed in the inner wall of the lock head, a copper bar and a spring are arranged in the lock cylinder, a slit is formed in the wall of the lock cylinder, a bolt is connected to the copper bar and penetrates through the slit in the lock cylinder, the end of the bolt is matched with the limiting clamping groove in the inner wall of the lock head, a positioning pin is arranged to limit the relative movement of the lock head and the lock cylinder in the axial direction, and the lock tongue is fixed on the lock cylinder through. The lock has the advantage of small volume, and when the lock is used, the copper bar is pushed by an outer polygonal key, the spring is compressed, the bolt is separated from the limit clamping groove, the key drives the lock cylinder to rotate (open or close), when the lock is rotated to a set position, the key is pulled out, and under the action of the spring, the bolt enters another limit clamping groove to be limited, so that the purpose of opening or locking is achieved. However, because the positioning pin is used for limiting the axial movement of the lock head and the lock core, although the lock head and the lock core can be disassembled, the gap between the lock core and the lock head is large, the lock body is easy to slide and damage, the positioning pin is easy to break after being stressed for a long time, the lock body is damaged, the service life is short, and meanwhile, the bolt is positioned with the lock core by the screw, and the strength is poor.
The prior art does not have a supporting and door locking device for a refrigerator door, and only has a plurality of refrigerator door locks similar to a refrigerator. Chinese patent "zhengsu province wu wen shi zhenghaohai" (chinese patent number 01245340.4), discloses a refrigerator door lock, and this refrigerator door lock includes tapered end, lock core and the spring bolt of connection on the lock core, be equipped with spacing draw-in groove on the inner wall of tapered end, be equipped with bar copper and spring in the lock core, be equipped with the slit on the lock core wall, its tip cooperates its characterized in that with the spacing draw-in groove of tapered end inner wall: the inner wall of the lock head is provided with an annular groove corresponding to the periphery of the lock core, and the lock further comprises an annular snap spring which is arranged in the ring formed by the annular grooves of the lock head and the lock core.
Although the refrigerator door lock has a certain function of axially positioning the lock head and the lock cylinder by using the snap spring, the structure is still complex, and the material cost of processing, manufacturing and assembling is high.
Chinese patent No. 91213149.7 entitled "nan jing ciwei and sheng of jiangsu province" discloses a refrigerator door lock, which comprises a decorative lock head, a double-sided tooth lock latch and a fixed bracket. The convex teeth with opposite directions of the teeth on the two sides of the double-side tooth lock bolt are utilized, so that the decorative lock head can be locked at the two ends of the lock bolt, and the matching requirements of various refrigerator sizes and structures are met.
The refrigerator door lock is installed on a foot supporting screw below a refrigerator door handle through a fixing support, obviously poor in stability, and small in application range because no door handle is arranged in the refrigerator at present.
