圆环活页夹机构
摘要：
一种用于固定活页面的圆环活页夹机构。该机构包括一细长板，由上述板支承，用于相对于该板作枢转运动的铰接板，及安装在铰接板上并可在一关闭位置和一打开位置之间移动的环形元件。一控制结构可控制地转动上述铰接板，从而在关闭位置与打开位置之间移动环形元件。该控制结构包括一位于该机构一端的单个致动件，一可相对于该细长板移动的运行条，和两个操作性地将运行条联接到铰接板上的联接件。该控制结构构造成选择性地将该机构放置在环形元件被紧紧关闭的一锁定位置。
摘要（英）：

The circular ring loose-leaf binder mechanism for binding loose leaves includes one slender sheet, one hinged sheet and ring elements installed in the hinged sheet and capable of shifting between oneclose position and one open position. One control structure is used to turn the hinged sheet, so that the ring elements are made to shift between the close position and the open position. The controlstructure includes one actuator at one end of the mechanism, one executing strip capable of shifting relatively to the slender sheet and two connecting parts to connect the executing strip to the hinged sheet for operation. The control structure is used to set the mechanism in the ring element-closing locking position optionally.
