摘要

PURPOSE: A height control screw structure is provided to easily control the height of such an electronic article with heavy load as a refrigerator and to prevent deformation of the exterior of the floor surface coming in contact with a height control screw although the height control screw is rotated to control the height of the electronic article to desired height. CONSTITUTION: In a height control screw structure, a height control screw is rotatably installed to a screw groove formed to the bottom surface of an electronic article(10). The height control screw structure comprises a first screw part fastened to the screw groove; a height control support part(50) rotated and combined to the lower end of the first screw part in a state capable of controlling the high and low; and a floor surface support part(60) rotatably combined to the lower end of the height control support part to support the load of the electronic article to the floor. The height control support part has a thread to the inside.
