A refrigerator hinge assembly

Abstract

The invention discloses a refrigerator hinge assembly and relates to the technical field of refrigerator hinges. The present invention includes a hinge assembly, the hinge assembly is used to connect the refrigerator body and the refrigerator door; the hinge assembly includes a hinge seat and a transmission device; wherein the transmission device includes a first connecting arm, a second connecting arm, a third connecting arm, an elastic structure and buffer structures. In the present invention, when the door of the refrigerator is opened and is 90° to the side of the refrigerator body, the second circular projection of the second connecting arm is limited by the first arc-shaped groove of the first connecting arm; meanwhile, the second circular projection of the second connecting arm The two arc-shaped limiting protrusions are limited by the protruding part on one side of the second arc-shaped groove, and cannot be opened to a larger angle; the structure is simplified, the installation is highly versatile, the stability and reliability are improved, and the refrigerator door is easy to open and close , takes up little space, and does not protrude from the box when the door is opened.

Description

technical field [0001] The invention belongs to the technical field of refrigerator hinges, in particular to a refrigerator hinge assembly. Background technique [0002] Existing refrigerator hinges are mainly composed of a hinge fixing plate and a hinge shaft. The hinge plate is fixed on a limit block and a retainer that cooperates with the hinge shaft and is fixed on the refrigerator door; when in use, the refrigerator door is pushed by hand, and the limit block The shaft hole and the hinge shaft rotate to realize closing or opening. The hinge structure is simple and low in cost. This hinge structure is used on most refrigerators, but the refrigerator door protrudes from the box when it is opened. Embedded refrigerators are becoming more and more popular among users, and the future market growth potential of the industry is huge. Embedded refrigerators require the door to be opened at 90°, and when the door is opened, the door cannot protrude from the box, otherwise it wil...

AI Technical Summary

Problems solved by technology

[0003] At present, the installation of hinges used in built-in refrigerators is complicated, the cost is high, the use is single, and the occupied space is large, which hinders the opening and closing of the refrigerator door, and it is easy to cause the refrigerator door to collide with the refrigerator frame. The thrust required to rotate the door body is relatively large, which is inconvenient to operate. There are many connection base points inside the hinge, and some connection base points are not fixed and move together with the door body, which is prone to unsmooth opening and closing of the door.
