The embodiment of the invention relates to the technical field of rotating shaft locking, in particular to a rotating shaft locking mechanism and an unmanned aerial vehicle arm, and the rotating shaft locking mechanism comprises a rotating shaft, a first rotating part, a second rotating part, a limiting part, a first elastic part, a second elastic part and the like. The limiting piece can be in key position fit with the first rotating piece and the second rotating piece respectively, and when the limiting piece is located at different positions, the rotating shaft locking mechanism can be in an unlocking state and a locking state respectively. The rotating shaft has the functions of a button and a knob, and the limiting piece and the first rotating piece can be separated from each other by pressing the rotating shaft, so that the first rotating piece and the second rotating piece are unlocked to realize rotation. And the first elastic piece and the second elastic piece can reset the rotating shaft and the limiting piece. And the rotating shaft and the first rotating piece can be switched between an unlocking state and a locking state by rotating the rotating shaft. Locking and unlocking of the rotating shaft are achieved through key position matching and the elastic piece, the rotating shaft locking function is achieved through a simple structure, reliability is good, operation is easy, and cost is low.

    本发明实施例涉及转轴锁定技术领域,特别涉及一种转轴锁定机构及无人机机臂,转轴锁定机构包括转轴、第一转动件、第二转动件、限位件、第一弹性件和第二弹性件等。限位件可分别与第一转动件和第二转动件形成键位配合,限位件位于不同位置时可使转轴锁定机构分别处于解锁和锁止状态。转轴兼具按钮、旋钮功能,按下转轴可使限位件和第一转动件脱离配合,使得第一转动件和第二转动件解锁,实现转动。第一弹性件和第二弹性件可使转轴及限位件复位。旋转转轴可以使转轴与第一转动件在解锁和锁定状态下切换。本发明通过键位配合以及弹性件实现转轴的锁定与解锁,通过比较简单的结构实现了转轴锁定功能,可靠性好、操作简单、成本低。
