    • A locking cap assembly is selectively locked into place within a tubular opening, such as the open end of a fire department connection. The locking cap assembly has an expandable element and a spreader element that is operatively connected to a locking bolt. As the locking bolt is rotated by a key, the spreader element is translated longitudinally through a tapered longitudinal bore in the expandable element, and the translation of the spreader element respectively expands and contracts the extendable element as the spreader element moves in the bore between first and second positions. The locking bolt includes a pair of cooperating lock washers having opposed cam surfaces, and a pair of opposed Bellville compression washers that apply axial pressure to the lock washers, allowing the locking bolt to be self locking during use for increased reliability and security.
    • 锁定盖组件被选择性地锁定在管状开口内,例如消防部门连接的开口端。 锁定帽组件具有可操作地连接到锁定螺栓的可扩张元件和吊具元件。 当锁定螺栓通过钥匙旋转时,吊具元件纵向平移通过可膨胀元件中的锥形纵向孔,并且当扩展元件在孔中在第一位置之间移动时,扩展元件的平移分别膨胀和收缩可延伸元件 和第二职位。 锁定螺栓包括一对具有相对的凸轮表面的配合的锁紧垫圈以及对锁定垫圈施加轴向压力的一对相对的Bellville压缩垫圈,从而允许锁定螺栓在使用期间自锁以提高可靠性和安全性。

    • A locking cap is selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap has an expandable sleeve and a spreader member. As a key is turned, the spreader member is drawn into the expandable sleeve which is urged outward. The outward movement of the expandable sleeve increases a frictional component such that the expandable sleeve becomes frictionally locked within the tubular opening. The key has an end design that is complemented by an end of an actuator shaft such that the likelihood of unauthorized removal of the locking cap is reduced.
    • 锁定帽被选择性地锁定在管状开口内,例如用于对建筑物喷洒系统充电的立管的开口端。 锁定帽具有可扩张套筒和吊具构件。 当钥匙转动时,吊具构件被拉到可向外推动的可膨胀套筒中。 可膨胀套管的向外运动增加摩擦部件,使得可膨胀套筒摩擦锁定在管状开口内。 钥匙具有末端设计,辅以致动器轴的端部,从而减少了未经授权的拆卸锁帽的可能性。
