FIXING SCREW STRUCTURE FOR ADJUSTING A FIXING PROCEDURE

摘要

A fixing screw structure for adjusting a fixing procedure used for fixing a panel to a casing, including a screw, an elastomer and a fixing frame. The screw includes a threaded portion and a tapered portion, and passes through the panel, and the threaded portion is screwed on the casing. The elastomer is annular and disposed around the screw, and has a taper hole corresponding to the tapered portion. The fixing frame is a hollow tube, and is fixed on the panel and positioned around the elastomer. When the screw is screwed, the tapered portion abuts the inner wall of the taper hole and the elastomer is expanded outwardly to fitly abut the inner wall of the fixing frame. The instant disclosure transforms the longitudinal screwing force into a transverse expanding force to fix the panel, thereby eliminating the cumulative tolerance of the casing and the panel.

1. A fixing screw structure for adjusting a fixing procedure used for fixing a panel to a casing, the panel has a via hole, the casing has a threaded hole, and the fixing screw structure comprises:
a screw comprising a threaded portion and a tapered portion, the tapered portion is a cone and has an outer diameter gradually decreased toward the direction of the threaded portion, the screw passes through the via hole of the panel, and the threaded portion of the screw screws into the threaded hole of the casing; an elastomer disposed around the screw, the elastomer has a first end and a second end, the first end is near to the casing, the elastomer has a taper hole, the taper hole has an inner diameter gradually decreased toward the direction of the first end; a fixing frame which is a hollow tube, one end of the fixing frame is fixed on the panel, the fixing frame is disposed around the elastomer; and when the screw is screwed toward the direction of the casing, the tapered portion of the screw abuts an inner wall of the taper hole of the elastomer and the elastomer is expanded outwardly to fitly abut the inner wall of the fixing frame and thereby fixing the panel to the casing.
