摘要： A pin latch (10) includes a housing (12), a handle (14) attached to the housing (12), a shear pin (110) attached to the handle (14), and a finger member (118) attached to the handle (14) and the shear pin (110). The handle (14) may be set in an intermediate position between open and closed positions. Trigger pins (140) slidably engage slots (128) formed within the finger member (118) until they engage stops (135) to retain the handle (14) in its intermediate position. To further retract the shear pin (110) and move the handle (14) towards the open position, the finger member (118) is lifted and the trigger pins (140) disengage the stops (135). Alternately, the latch (10) includes a button mechanism (372) having a cross-pin (384) that engages a stop (344) formed by a slot (342) within the shear pin (330) to maintain the handle (214) in its intermediate position. To further retract the shear pin (330) and rotate the handle (214), the button mechanism (372) is depressed to disengage the cross-pin (384) from the slot (342) of the shear pin (330).
摘要翻译：销闩（10）包括壳体（12），附接到壳体（12）的手柄（14），附接到手柄（14）的剪切销（110）和附接到手柄手柄（14）和剪切销（110）。手柄（14）可以设置在打开位置和关闭位置之间的中间位置。触发销（140）可滑动地接合形成在指状构件（118）内的槽（128），直到它们接合止动件（135）以将把手（14）保持在其中间位置。为了进一步缩回剪切销（110）并将手柄（14）朝向打开位置移动，指状构件（118）被提升，并且触发销（140）脱离止动件（135）。替代地，闩锁（10）包括具有交叉销（384）的按钮机构（372），该交叉销接合由剪切销（330）内的狭槽（342）形成的止动件（344），以保持手柄（214）在其中间位置。为了进一步缩回剪切销（330）并旋转手柄（214），按钮机构（372）被压下以使交叉销（384）与剪切销（330）的槽（342）脱离。
