A supporting leg for a refrigerator comprises a flanging portion formed in the mode that a hinge fixedly connected with a refrigerator body of the refrigerator extends towards the bottom of the refrigerator body of the refrigerator. The bottom of the flanging portion is provided with a stud perpendicular to the ground. The bottom of the stud is provided with an adjusting rotary knob matched with the stud. The adjusting rotary knob is provided with internal threads matched with the stud. When the supporting leg is installed, the adjusting rotary knob just needs to be rotated to the stud until the refrigerator is adjusted to be at the horizontal position. Due to the arrangement, the stud cannot be exposed out of the refrigerator, the whole appearance of the refrigerator is more attractive, and potential safety hazards are avoided.
