Hidden type folding hinge of double-sliding door
The invention belongs to the technical field of hinges, and relates to a hidden type double-push-door folding hinge which comprises a connecting piece, a door frame hinge, a door leaf hinge, a first key shaft, a second key shaft, a first positioning ring, a second positioning ring, a first spring and a second spring, the door frame hinge comprises a first shaft barrel and a first fixing piece, and the door leaf hinge comprises a second shaft barrel and a second fixing piece. Two first outer shaft barrels are arranged on one side of the connecting piece, two second outer shaft barrels are arranged on the other side of the connecting piece, the first shaft barrels are hinged between the two first outer shaft barrels, the second shaft barrels are hinged between the two second outer shaft barrels, and the first positioning ring and the second positioning ring are each of a fluctuating structure. The section contours of the first key shaft and the second key shaft are both divided into a plurality of discontinuous concentric arc edges, the first positioning ring is provided with a first through hole, and the second positioning ring is provided with a second through hole. The folding hinge enables a door to be opened in two directions, is installed in a hidden mode, and enables a door leaf to stay at a specific opening degree.
本发明属于铰链技术领域，涉及一种隐藏式双推门折叠合页，包括连接件、门框合页、门扇合页、第一键轴、第二键轴、第一定位环、第二定位环、第一弹簧和第二弹簧，门框合页包括第一轴筒和第一固定片，门扇合页包括第二轴筒和第二固定片，连接件的一侧设有两个第一外轴筒，另一侧设有两个第二外轴筒，第一轴筒铰接在两个第一外轴筒之间，第二轴筒铰接在两个第二外轴筒之间，第一定位环和第二定位环均具有起伏结构，第一键轴与第二键轴的截面轮廓均被分隔为若干不连续的同心弧边，第一定位环具有第一通孔，第二定位环具有第二通孔。本折叠合页使门可双向打开，隐藏式安装，能让门扇停留在特定的开度。
