The invention provides an aircraft cabin door actuator cylinder with an internal lock mechanism. The aircraft cabin door actuator cylinder comprises a steel ball (3), an upper clamping ring (14), a lower clamping ring (15), a piston (11) and matched parts. The steel ball (3) is located in the middle of the piston (11), and the upper clamping ring (14) and the lower clamping ring (15) are correspondingly arranged at the two ends of the piston (11). The steel ball (3) is pressed to retract in the radial direction through the piston (11), the piston (11) exits the inner wall of the upper clampingring (14) or the lower clamping ring (15), the upper clamping ring (14) or the lower clamping ring (15) rebounds automatically to complete unlocking, the steel ball (3) contracts under the pressure of hydraulic oil, and the piston (11) is driven by the hydraulic oil to achieve reciprocating motion of the actuator cylinder. The aircraft cabin door actuator cylinder with the internal lock mechanismis simple and reliable in structure, stable in unlocking pressure and stable in telescopic motion.

    本发明提供一种带内锁机构的飞机舱门作动筒,包括钢球(3)、上卡环(14)、下卡环(15)、活塞(11)和配套零部件,钢球(3)位于活塞(11)中部位置,上卡环(14)和下卡环(15)分置于活塞(11)两端,通过活塞(11)的移动压迫钢球(3)沿径向收缩,活塞(11)退出上卡环(14)或下卡环(15)内壁,上卡环(14)或下卡环(15)自动回弹,从而完成解锁,钢球(3)在液压油的压力下收缩,活塞(11)在液压油的驱动下实现作动筒的往复运动。该带内锁机构的飞机舱门作动筒结构简单可靠、开锁压力稳定、伸缩运动平稳。
