Background

Currently, in the existing refrigerator market, the conventional three-door refrigerator is getting mature.

Next, the stud bolt 400, the stud bolt 500, and the screw 600 are fixed to the first boss 310, the second boss 320, and the third boss 330 of the reinforcement 300, respectively, and then the second lock nut 440 is screwed to the second screw portion 404 of the stud bolt 400, the second lock nut 540 is screwed to the second screw portion 504 of the stud bolt 500, and the nut 610 is screwed to the screw portion 601 of the screw 600.

Again, the first protrusion 210, the second protrusion 220, and the third protrusion 230 of the upper hinge 200 are respectively engaged with the first protrusion 310, the second protrusion 320, and the third protrusion 330 of the reinforcement 300. The oval through-hole 211 of the first protrusion 210 of the upper hinge 200 is caught outside the polish rod portion 402 of the stud bolt 400, and the first locking nut 410 is screwed on the first screw portion 401 of the stud bolt 400 such that the first protrusion 210 of the upper hinge 200 is located between the first locking nut 410 and the stopper portion 403 of the stud bolt 400. The notch 221 of the second protrusion 220 of the upper hinge 200 is caught outside the polish rod portion 502 of the stud bolt 500, and the first locking nut 510 is screwed on the first screw portion 501 of the stud bolt 500, so that the second protrusion 220 of the upper hinge 200 is located between the first locking nut 510 and the stopper portion 503 of the stud bolt 500. The notch 231 of the third protrusion 230 of the upper hinge 200 is caught outside the polish rod portion 602 and/or the screw portion 601 of the screw 600, so that the third protrusion 230 of the upper hinge 200 is located between the third protrusion 330 of the reinforcement 300 and the head 603 of the screw 600.

Finally, according to the flush degree of the door body, the second screw portion 404 of the stud bolt 400 is rotated with respect to the screw hole 311 of the first boss 310 of the reinforcement member 300 by using a socket head cap screw through the socket head cap hole 405 of the stud bolt 400, so that the distance between the stopper portion 403 of the stud bolt 400 and the first boss 310 of the reinforcement member 300 is changed, that is, the distance between the first boss 210 of the upper hinge 200 and the first boss 310 of the reinforcement member 300 is changed, and the upper hinge 200 is moved forward and backward. Meanwhile, according to the flush degree of the door body, the second screw portion 504 of the stud 500 is rotated with respect to the screw hole 321 of the second protrusion 320 of the reinforcement 300 by using a hexagon socket screw through the hexagon socket 505 of the stud 500, so that the distance between the stopper portion 503 of the stud 500 and the second protrusion 320 of the reinforcement 300 is changed, that is, the distance between the second protrusion 220 of the upper hinge 200 and the second protrusion 320 of the reinforcement 300 is changed, and the upper hinge 200 is moved left and right. After the door body is flush, the second lock nut 440 and the second lock nut 540 are locked, the lock nut 610 is locked, and the first lock nut 410 and the first lock nut 510 are locked, so that the upper hinge 200 is fixed firmly.

When the front, rear, left and right positions of the upper hinge 200 need to be adjusted again, only the lock nuts related to the adjustment may be loosened, or all the lock nuts may be loosened and adjusted, and the process is not described in detail herein.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
