    • A locking device of the type having a lock cylinder containing a lock plug with a threaded rod connected thereto in a manner causing rotation of the rod with rotation of the lock plug by a key operating the tumbler includes a relatively massive cylindrical lock housing having a bore extending axially therethrough, the lock cylinder being fastened against rotational and axial movements relative to the lock housing, and a relatively massive cylindrical sleeve member with a blind bore therein and a screw threaded surface arrangement in a portion of the blind bore for threadingly engaging the threaded rod. In accordance with a first embodiment, relative rotation between the lock housing and the sleeve member is prevented by a counterbore in an open end of the blind bore of the sleeve member of non-circular transverse cross section and a portion of the exterior of the lock housing of reduced circumference, non-circular transverse cross section that is at least partially receivable in the counterbore. In accordance with a second embodiment, such relative rotation between the lock housing and the sleeve member is effectuated by a pair of pivotally connected semi-annular shackle members, the sleeve and lock housing being tangentially secured to a free end of a respective one of each of the semi-annular members. A cover cap assembly is provided which weatherproofs the lock cylinder and may serve to protect and camouflage a fastening screw for the lock cylinder.
    • 一种具有锁定装置的锁定装置,该锁定装置具有锁定塞,所述锁定筒具有连接到其上的螺纹杆,所述锁定塞以通过操作所述制动栓的键旋转所述杆而使所述杆旋转的方式包括相对大量的圆柱形锁定壳体, 所述锁定圆柱体相对于所述锁定壳体紧固抵抗旋转和轴向运动,以及相对大的圆柱形套筒构件,其中具有盲孔,并且所述盲孔的一部分中的螺纹表面布置用于螺纹地接合所述螺纹 竿。 根据第一实施例,通过非圆形横截面的套筒构件的盲孔的开口端中的沉孔和锁的外部的一部分来防止锁壳和套筒构件之间的相对旋转 减少圆周的外壳,至少部分地可接收在沉孔中的非圆形横截面。 根据第二实施例,锁定壳体和套筒构件之间的这种相对旋转通过一对枢转连接的半环形钩环构件来实现,套筒和锁定壳体切向地固定到每个相应的一个的自由端 的半环形构件。 提供了一种盖帽组件,其防止锁定气缸的防水,并且可用于保护和伪装用于锁芯的紧固螺钉。
