    • A door latching system for securing an armored door or window includes a latch assembly which is bolted to the interior of an armored door, a handle assembly which is welded to the exterior of the armored door and a strike plate which is welded to a vehicle structure or an armored side plate. The latch functions by moving an interior handle or an exterior handle in a rotary motion, which rotates a square key stock to which a cam is attached that retracts a latch. The latch is spring-loaded which allows the latch to extend to its original position when a handle is released. The springs also move the handles back to their original locations when released. When the door is shut the latch is pushed back by the strike plate, which moves the latch away from the cam, thus allowing the door to close and latch without movement of the handles. The strike plate has a roller mounted on it, which allows the latch to roll on it when the door is closed. An optional locking system allows the latching system to be secured in a latched or locked position such that the door or window to which it attached may only be readily opened from inside the vehicle.
    • 用于固定装甲门或窗的门闩系统包括:螺栓连接到装甲门的内部的闩锁组件,焊接到装甲门外部的手柄组件和焊接到车辆结构的冲击板 或装甲侧板。 闩锁通过使旋转运动中的内部手柄或外部手柄移动而起作用,该旋转运动使安装有凸轮的方形钥匙库旋转,卡扣可缩回。 闩锁是弹簧加载的,当手柄被释放时,闩锁允许闩锁延伸到其初始位置。 释放时,弹簧还可将手柄移回原位。 当门关闭时,闩锁被撞击板推回,撞板将闩锁从凸轮移开,从而允许门关闭并锁定,而不会移动手柄。 撞板具有安装在其上的辊,当门关闭时允许闩锁滚动。 可选的锁定系统允许锁定系统被固定在锁定或锁定位置,使得其附接的门或窗可以容易地从车辆内部打开。
