When one end of the sliding clip 400 is clipped into the clip groove 110, the guide groove 300 and the clip groove 110 are locked, so that the hinge shaft 200 cannot rotate relative to the hinge plate 100, and at this time, the door of the refrigerator is locked, and the sealability is improved. When one end of the sliding clip 400 is released from the clip groove 110, the guide groove 300 and the clip groove 110 can rotate relatively, so that the hinge shaft 200 can rotate relative to the hinge plate 100, and at this time, the door body of the refrigerator is unlocked and can be opened at will. The sealing of the refrigerator is realized by utilizing the hinge component of the refrigerator, so that the cost of the refrigerator is reduced, and the occupation of space is reduced.

Illustratively, when the opening of the guide slot 300 at one end of the hinge shaft 200 is aligned with the slot 110 at the inner side of the hinge plate 100, the guide slot 300 is communicated with the slot 110, and if the hinge shaft 200 needs to be locked with the hinge plate 100, the sliding clip 400 is slid toward the slot 110 to a position of being snapped into the slot 110, so as to limit the rotation of the hinge shaft 200, and the hinge shaft 200 is locked with the hinge plate 100 relatively; when the hinge shaft 200 is required to be unlocked from the hinge plate 100, the sliding clip 400 is slid back to the clip slot 110, so that the sliding clip 400 is separated from the clip slot 110, and at this time, the hinge shaft 200 can rotate relative to the hinge plate 100, and the hinge shaft 200 and the hinge plate 100 are unlocked.
