The invention discloses a space-saving opening and closing device. The space-saving opening and closing device comprises a frame and a door plate, wherein the frame is provided with a door opening. The space-saving opening and closing device further comprises a supporting assembly, a guiding assembly and a sliding assembly, wherein the supporting assembly comprises a crank connecting rod; the twoends of the crank connecting rod are rotationally connected with the frame and the door plate respectively; the guiding assembly comprises a sliding guide rod which is fixed to the frame; the slidingassembly comprises a sliding block and a sliding connecting rod; the sliding block is installed on the sliding guide rod in a sliding mode; and the two ends of the sliding connecting rod are rotationally connected with the sliding block and the door plate respectively. Through the design, the track of the door plate during opening and closing is changed from an existing arc protruding towards theinterior of a door to an arc sunken towards the interior of the door, and the occupied internal available space is small; and in addition, an operation assembly is rotationally installed in a containing space of the door plate and can be contained in the containing space of the door plate, and an operator can synchronously monitor the operation surface and the internal condition without displacement when the door is opened and closed.
本发明公开了一种节省空间的开合装置,包括框架及门板,框架设有门洞,节省空间的开合装置还包括支撑组件、导向组件以及滑动组件,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,导向组件包括滑动导杆,滑动导杆固定于框架,滑动组件包括滑块及滑动连接杆,滑块滑动安装于滑动导杆,滑动连接杆两端分别与滑块及门板转动连接,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;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。
