    • An axial pin tubular lock for use in securing portable computers and other devices having spindle-accepting ports. The lock is bade up of an outer shell attached to a cable, an inner shell, a rotatable driver sleeve, a stationary tumbler sleeve, a rear scuff plate held in place by a combination of an adhesive and cooperative geometric engagement with the outer shell, a locking spindle extending through the driver and tumbler sleeves, a retaining plate and an anti-rotation extension which may be integrally formed with the retaining plate. The rotatable driver sleeve is equipped with an internally disposed detent which engage a groove on the spindle, thereby providing proper axial and radial alignment between the spindle and the driver sleeve. The internal surface of the stationary tumbler sleeve has an indented support surface, thus providing spindle support while permitting passage of the spindle head through the tumbler sleeve during assembly. The tumbler sleeve is held in place by a pin which engages a slot located on the sleeve's outer perimeter and by the retaining plate which is disposed against the sleeve's rearward face. The retaining plate is, in turn, held in place by both a spring and the spline detail of the inner shell. The spindle itself incorporates a curved surface design which distributes forces more evenly across the spindle surface, thereby reducing the potential for spindle failure.
    • 一种用于固定便携式计算机和具有主轴接收端口的其他装置的轴向销管状锁。 锁定装置是附接到电缆的外壳,内壳,可旋转的驱动器套筒,固定的翻转套筒,后挡板通过粘合剂和与外壳的协作几何接合的组合而保持在适当的位置, 延伸穿过驾驶员和翻转套筒的锁定心轴,可与保持板一体形成的保持板和防旋转延伸部。 可旋转的驱动器套筒配备有内部设置的制动器,其接合主轴上的凹槽,从而在主轴和驱动器套筒之间提供适当的轴向和径向对准。 固定转筒套的内表面具有凹入的支撑表面,从而提供主轴支撑,同时允许主轴头在组装期间通过制动栓套筒。 制动栓套筒通过销钉固定在适当的位置,该销钉接合位于套筒的外周边上的狭槽和靠在套筒的后表面上的保持板。 保持板又通过弹簧和内壳的花键细节保持在适当的位置。 主轴本身结合了一个曲面设计,可以将力均匀地分布在主轴表面上,从而降低主轴故障的可能性。
