    • A latching mechanism that uses lubricant impregnated bearings to improve the operation, reduce the corrosion, ease the maintenance, and extend the life of the latching mechanism. The latching mechanism comprises a spindle rotatably disposed in a sleeve that is fixed to a frame (e.g., a door frame). Positioned in the annular space between the spindle and sleeve, the lubricant impregnated bearings separate dissimilar materials and provide a constant source of lubrication. To replenish the bearings, lubricant is introduced into the annular space through a channel in the spindle that communicates between an inlet opening in the end of the spindle and an outlet opening at the annular space. The lubricant impregnated bearings are grooved to enhance lubricant flow and distribution around the bearing surfaces. A shield is attached to the spindle and is disposed around the exterior of the sleeve to prevent debris from entering the annular space. The latching mechanism is suitable for use on doors, windows, hatches, scuttles, or other openings requiring a watertight seal.
    • 一种使用润滑剂浸渍轴承来改善操作,减少腐蚀,易于维护并延长锁定机构寿命的闭锁机构。 锁定机构包括可旋转地设置在固定到框架(例如,门框)的套筒中的主轴。 位于主轴和套筒之间的环形空间中,润滑剂浸渍的轴承分离不同的材料并提供恒定的润滑源。 为了补充轴承,润滑剂通过主轴中的通道引入环形空间,该通道在主轴端部的入口和环形空间的出口之间连通。 润滑剂浸渍的轴承是开槽的,以增强润滑剂在轴承表面周围的流动和分布。 屏蔽件附接到主轴并且设置在套筒的外部周围以防止碎片进入环形空间。 闭锁机构适用于需要防水密封的门,窗,舱口,sc条或其他开口。
