Further, the heights of the door closing guide boss and the door opening guide boss are smaller than the height of the hinge shaft.
Further, the depth of the door opening guide groove and the door closing guide groove is smaller than that of the shaft hole.
Further, a protruding portion is arranged on one side of the hinge.
Furthermore, the hinge body and the hinge shaft are both made of metal materials, and the shaft sleeve is made of wear-resistant materials; the hinge body and the hinge shaft are made of galvanized steel, zinc alloy and the like, and the shaft sleeve is made of POM and the like.
Further, a mounting hole is formed in one side of the hinge body, the hinge penetrates through the mounting hole through a bolt to be connected with a refrigerator body of the refrigerator, and the shaft sleeve is fixedly connected with a door body of the refrigerator.
Further, when the hinge is closed, the hinge is clamped with the protruding part of the hinge through the self-locking structure of the shaft sleeve, so that the refrigerator body and the door body of the refrigerator are in sealing connection.
The invention has the beneficial effects that:
(1) According to the hinge device for the refrigerator variable track door opening, the bosses are arranged on the two sides of the hinge shaft, and the guide grooves are arranged in the shaft sleeve, so that the door body is displaced in the rotating motion process, the size of the door body exceeding the outer side of the refrigerator body in the opening and closing process is reduced, and accordingly the placing gaps on the two sides of the refrigerator are reduced.
(2) The hinge device for the refrigerator variable track door opening is simple in structure and convenient to install.
