Description

Hinge and refrigerator comprising same Technical Field The utility model relates to the field of refrigerators, in particular to a hinge and a refrigerator comprising the hinge. Background The refrigerator hinge is a connecting piece for opening the refrigerator door body in the most common use at present, the hinge connects the refrigerator door body and the refrigerator body, and the door body can rotate relative to the refrigerator body so as to open or close a storage chamber of the refrigerator body. In order to realize that the door body of the refrigerator can have good closing performance with the refrigerator body of the refrigerator after being opened or closed, the existing refrigerator hinge generally adopts a six-link transmission mechanism, damping of a pure mechanical structural type is arranged in the refrigerator hinge, and the main functions are that the door opening speed is gentle, collision impact is reduced and the like. The hinge comprises a first hinge seat, a second hinge seat and a transmission assembly, wherein the first hinge seat is arranged on the box body, the second hinge seat is arranged on the door body, the transmission assembly is hinged between the first hinge seat and the second hinge seat, the front end of the transmission assembly is hinged with the first hinge seat, and the rear end of the transmission assembly is hinged with the second hinge seat. The transmission assembly further comprises a first transmission rod, a second transmission rod, a third transmission rod and a fourth transmission rod, wherein the front end of the first transmission rod is hinged with the first hinge seat through a first hinge point, the front end of the second transmission rod is hinged with the first hinge seat through a second hinge point, the rear end of the first transmission rod is hinged with the front end of the third transmission rod through a third hinge point, the rear end of the third transmission rod is hinged with the second hinge seat through a fourth hinge point, the front end of the fourth transmission rod is hinged with the middle part of the second transmission rod through a fifth hinge point, the rear end of the fourth transmission rod is hinged with the second hinge seat through a sixth hinge point, and the rear end of the second transmission rod is hinged with the middle part of the third transmission rod through a seventh hinge point.
