The invention aims to solve the technical problems that: the invention provides a low-cost hinge device for a refrigerator variable track door opening, which can effectively reduce the size of a protruding box body outside a door body in the door opening and closing process, and can also reduce the required distance between two sides of the refrigerator and a cabinet or a wall. The occupied space of the refrigerator is saved, and the clearance between the side surface of the refrigerator and a cabinet or a wall is reduced, so that the overall appearance is better.

The technical scheme adopted for solving the technical problems is as follows: a hinge device for a refrigerator variable track door comprises a hinge and a shaft sleeve; the hinge comprises a hinge body and a hinge shaft, wherein a door closing guide boss and a door opening guide boss are arranged on two sides of the hinge shaft; the shaft sleeve is provided with a shaft hole, a door opening guide groove, a door closing guide groove and a self-locking structure, and the shaft hole is in a waist circle shape; the hinge shaft is sleeved in the shaft hole;

the maximum opening and closing angle between the refrigerator door and the refrigerator body is 120-135 degrees.

When the refrigerator is opened, when the included angle between the refrigerator door body and the refrigerator body is smaller than the middle angle, the door opening guide groove of the shaft sleeve is contacted with the door opening guide boss on the hinge body, so that the refrigerator door body rotates and generates certain offset; when the included angle reaches the middle angle, the center of the outer edge of one side of the door body, which is close to the box body, moves from the center A point of the arc on one side of the shaft hole, which is far away from the self-locking structure, to the center B point of the arc on the other side of the shaft hole; when the included angle is larger than the middle angle, the door opening guide groove is separated from the door opening guide boss, and the door body only rotates around the point B, so that the size of the outer edge of the door body, which is beyond the box body, is reduced because the point B is closer to the inner side of the box body than the point A;

when the door is closed, the door body only rotates around the point B when the included angle between the door body and the refrigerator body is larger than the middle angle; when the contained angle is less than the intermediate angle, the door closing guide slot on the shaft sleeve contacts with the door closing guide boss on the hinge body, so that the door body generates offset when rotating, the door body moves from the point B to the point A from the intermediate angle to the closing completion process of the door body, and simultaneously, the self-locking structure is clamped with the shaft sleeve after the door body is closed, so that the refrigerator door body is sealed with the refrigerator body.

Further, the door closing guide boss is matched with the door closing guide groove, and the door opening guide boss is matched with the door opening guide groove.

Further, the door opening guide groove and the door closing guide groove are arranged on two sides of the shaft hole.

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.
