The invention discloses a space-saving opening and closing mechanism, which comprises a frame and a door plank, the frame is provided with a door opening, the space-saving opening and closing mechanism further comprises a supporting assembly and a magnetic attraction assembly, the supporting assembly comprises a crank connecting rod, the two ends of the crank connecting rod are rotationally connected with the frame and the door plank correspondingly, and the magnetic attraction assembly comprises a magnetic attraction piece which is installed at the end of the door plank; the magnetic attraction piece is adsorbed on the frame and can move relative to the frame; by means of the design, when the door plank is opened and closed, an existing arc protruding towards the interior of the door is changed into an arc sunken towards the interior of the door, and the occupied internal usable space is small; the magnetic attraction piece can be separated from the frame, and the door plank can be opened to the maximum angle relative to the frame to facilitate access; in addition, the operation assembly is rotationally installed in the containing space of the door plank and can be contained in the containing space of the door plank, and when the door is opened and closed, an operator can synchronously monitor the operation face and internal conditions without displacement.

    本发明公开了一种节省空间的开合机构,包括框架及门板,框架设有门洞,节省空间的开合机构还包括支撑组件以及磁吸组件,支撑组件包括曲柄连杆,曲柄连杆两端分别与框架及门板转动连接,磁吸组件包括磁吸件,磁吸件安装于门板端部,磁吸件与框架吸附并能相对框架移动,通过上述设计,门板打开及关闭时的轨迹由现有的向门内部凸出的圆弧变为向门内部凹陷的弧形,占用内部可使用空间少;磁吸件能够与框架分离,此时门板相对框架能够打开到最大角度,方便进出;此外操作组件转动安装于门板的收容空间并能收容于门板的收容空间,开闭门时操作人员免位移即可同步监控操作面与内部情况。
