The invention relates to a multi-rotor unmanned aerial vehicle pluggable arm locking and loosening preventing device and an unmanned aerial vehicle, belongs to the technical field of unmanned aerial vehicles, and can overcome the defects that a folding arm locking structure is complex and prone to fatigue and loosening and solve the problem that a pluggable arm locking structure only locks but does not prevent arms from loosening. The device comprises a machine arm, a threaded locking ring, an anti-loosening mechanism, a guide ring and a machine arm seat, the threaded locking ring is arranged at the joint of the arm and the arm seat in a sleeving manner and is in threaded connection with the arm seat; the anti-loosening mechanism is arranged on the machine arm and is connected with the thread locking ring; the guide ring is fixedly arranged at the connecting end of the vehicle arm and is connected with the connecting end of the vehicle arm seat in a positioning manner; the threaded locking ring is provided with an internal thread, a check ring at the end part and meshing teeth; the internal thread is in threaded connection with the arm seat; the check ring blocks the guide ring to enable the guide ring to be tightly connected with the arm seat; the meshing teeth are connected with the meshing teeth in the anti-loosening mechanism in a meshing mode, and the anti-loosening effect is achieved.

    本发明涉及一种多旋翼无人机插拔式机臂锁紧防松装置及无人机,属于无人机技术领域,能够改善折叠式机臂锁紧结构复杂易疲劳松动的缺点以及解决插拔式机臂锁紧结构只锁紧没有防止机臂松脱的问题;该装置包括机臂、螺纹锁紧环、防松机构、导向环和机臂座;所述螺纹锁紧环套设在所述机臂和所述机臂座的连接处,并与所述机臂座螺纹连接;所述防松机构设置在所述机臂上且与所述螺纹锁紧环连接;所述导向环固定设置在所述机臂的连接端,并与所述机臂座的连接端定位式连接;螺纹锁紧环设有内螺纹、端部的挡圈和啮合齿;内螺纹与机臂座螺纹连接;挡圈档紧导向环使之与机臂座紧密连接;啮合齿与防松机构中的啮合齿啮合连接,起到防松作用。
