AI Technical Summary

Technical Problem

The existing self-closing rollers are installed on the door fixing seat, leaving no space on the door fixing seat to install screws and other fasteners, resulting in low fixing strength and easy loosening.

Method used

Design a self-closing hinge, wherein a roller is rotatably mounted on a first connecting member, and an elastic component is rotatably mounted on a second connecting member. When the self-closing hinge is in the fully open state, the elastic component is locked with the second connecting member and is in a compressed state; when in the critical state, the elastic component abuts against the roller, and the elastic component restores its deformation to drive the hinge to rotate towards the closed state. The roller is rotatably mounted on the first connecting member, and there is space in the door fixing seat to install a fixing member.

Benefits of technology

It improves the stability of the door fixing seat and the door body, prevents loosening, and enhances the structural strength of the self-closing hinge.

Abstract

The utility model discloses a kind of self-closing hinges and refrigerator, including cabinet fixed seat, door body fixed seat, first connecting piece, second connecting piece, third connecting piece, fourth connecting piece and self-closing structure, the roller of self-closing structure is rotatably installed in first connecting piece, elastic component is rotatably installed in second connecting piece, when self-closing hinge is in completely open state, elastic component is locked with second connecting piece and elastic component is in compression state;When self-closing hinge is in critical state, elastic component is unlocked with second connecting piece and thus is in conflict with roller, elastic component restores deformation and rotates relative to second connecting piece, the elastic force of elastic component drives self-closing hinge to close state activity, through the above design, the roller is rotatably installed in first connecting piece, there is space mounting fixture in door body fixed seat, make the fixation of door body fixed seat and door body more stable, not easy to come loose.
