The invention relates to the technical field of aircraft tail boom supporting columns, and discloses a tail boom supporting column with a locking function, the tail boom supporting column comprises an actuating cylinder and a supporting seat connected with the output end of the actuating cylinder, the actuating cylinder comprises an outer cylinder and a piston rod sliding on the outer cylinder, the supporting seat comprises a base, a tail connecting rod is arranged on the piston rod, and the base is connected with the tail connecting rod; and a mechanical lock is arranged on the outer cylinder. The mechanical lock is arranged, so that the actuating cylinder has a locking function, misoperation of the actuating cylinder is prevented, and the operation stability of the actuating cylinder is improved; due to the fact that the locking spring A and the locking spring B provide pre-pressure, unlocking can only be conducted when the oil pressure needs to be larger than the pre-pressure, the unlocking threshold value is changed by changing the pre-pressure, and simplicity and convenience are achieved. The tail connecting rod is connected with the base through the spherical surface, so that the base can ensure the overall stability of the aircraft by rotating the angle and adjusting the supporting point if the ground is uneven or suffers from an extremely severe environment after the aircraft lands.

    本发明涉及飞机尾撑支柱技术领域,公开了一种带锁定功能的尾撑支柱,包括作动筒以及与作动筒输出端连接的支撑座,作动筒包括外筒以及滑动在外筒上的活塞杆,支撑座包括底座,活塞杆上设置有尾接杆,底座与尾接杆连接;所述外筒上设置有机械锁。本发明通过设置机械锁,使得作动筒具有锁定功能,防止作动筒误动作,提高其作业的稳定性;由于上锁弹簧A、上锁弹簧B提供预压力,使得油压需要大于该预压力时才能解锁,通过该变预压力的大小来改变解锁阈值,简单便捷;通过设置尾接杆与底座通过球面连接,在飞机着陆后若地面不平整或遭受极端恶劣环境,底座可以通过转动角度,调节支撑点,来保证飞机整体的稳定性。
