The invention provides a hinge structure for a refrigerator. The hinge structure comprises a pivot, a fixed hinged support, a rotating hinged support, a torsional spring, a first latch and a second latch. The pivot penetrates through the fixed hinged support and the rotating hinged support; the first latch is fixedly mounted on the pivot; the second latch is fixedly mounted on the fixed hinged support; the first latch is provided with a plurality of first helical teeth which are arranged in a circle in the circumferential direction; the second latch is provided with second helical teeth which are the same as the first helical teeth in number and surround the pivot in the circumferential direction; the torsional spring is arranged between the pivot and a cabinet door; the rotating hinged support extends to form an elastic protruding tongue located beside the pivot; the fixed hinged support is provided with a protruding arched structure; the elastic protruding tongue is aligned with the arched structure in the rotating direction of the rotating hinged support; the elastic protruding tongue and the arched structure are blocked under the action of the torsional spring when the rotating hinged support is switched to an opening position; the elastic protruding tongue crosses the arched structure through elastic deformation in the process that the rotating hinged support is switched to a closing position; and the hinge structure for the refrigerator ensures rapid positioning after opening, and is convenient for the closing operation and adjustable in torsion.
本发明提供了一种冷柜用铰链结构，包括枢轴、固定铰座、转动铰座、扭簧、第一卡齿和第二卡齿。枢轴穿置于固定铰座和转动铰座，第一卡齿固定装于枢轴，第二卡齿固定装于固定铰座，第一卡齿设有多个在周向上排成一圈的第一斜齿牙，第二卡齿设有数量与第一斜齿牙相同并从周向包围枢轴的第二斜齿牙；扭簧设于枢轴与柜门之间；转动铰座延伸出位于枢轴旁边的弹性凸舌，固定铰座设有凸起的拱起结构，弹性凸舌沿转动铰座的转动方向与拱起结构对齐，弹性凸舌在转动铰座切换至打开位置时且在扭簧的作用下与拱起结构相阻挡，弹性凸舌在转动铰座转换至收合位置的过程中通过弹性变形而越过拱起结构；确保打开后的快速定位，且便于收合操作及扭力可调。
