The invention discloses an unmanned aerial vehicle folding arm locking joint, an arm and an unmanned aerial vehicle, and relates to the technical field of fastening. In order to solve the technical problems that in a locking structure of an existing unmanned aerial vehicle folding arm in the prior art, due to the fact that the friction force of a locking piece is large, larger force is needed to operate the locking piece for locking and unlocking, and the locking piece is not convenient to use, the technical scheme is that the locking joint of the unmanned aerial vehicle folding arm is provided. Comprising a fixed base, a movable base and a locking wrench, the fixed base is movably connected with the movable base; a groove is further formed in the fixed base, a locking piece is arranged on the locking wrench, and the locking piece is driven by the locking wrench to fall into the groove, so that the joint is in a locked state; the angle between the circle center connecting line of two circles where the projections of the rolling wheel and the small rotating shaft are located and the circle center connecting line of two circles where the projections of the rolling wheel and the large rotating shaft are located is not smaller than 90 degrees. The method is suitable for design work of unmanned aerial vehicle arms.

    无人机折叠机臂锁紧关节、机臂和无人机,涉及用于紧固的技术领域。为解决现有技术中存在的,现有无人机折叠机臂的锁紧结构中因为锁紧件摩擦力较大,需要更大的力气来进行操作锁定件来锁定和解锁,不利于锁定件的方便使用的技术问题,本发明提供的技术方案在于:无人机折叠机臂锁紧关节,包括:固定基座、活动基座,和锁定扳手;固定基座与活动基座活动连接;固定基座上还设置有凹槽,锁定扳手上设置有锁紧件,锁紧件被锁定扳手带动,落入凹槽中,使关节处于锁紧状态;锁紧件为滚轮,滚轮和小转轴的投影所在的两个圆的圆心连线与滚轮和大转轴的投影所在的两个圆的圆心连线之间的角度不小于90度。适合应用于无人机机臂的设计工作中。
