The invention discloses a locking and folding structure for an arm joint. The locking and folding structure comprises a central disc cantilever assembly, an arm folding assembly and a threaded sleeve assembly. According to the unmanned aerial vehicle, the threaded sleeve is tightly matched with the center disc inner part, the threaded sleeve presses the vehicle arm inner part, so that the vehicle arm folding assembly and the center disc cantilever assembly are stably connected, meanwhile, the designed threaded sleeve looseness stopping assembly can stop looseness of the threaded sleeve assembly, and the flight safety and reliability of the unmanned aerial vehicle are improved. According to the unmanned aerial vehicle, the first rotating shaft pin and the second rotating shaft pin, connected with the folding adapter, of the vehicle arm folding assembly rotate around the shaft twice, so that when the vehicle arm folding assembly is folded, the vehicle arm folding assembly does not interfere with other assemblies of the unmanned aerial vehicle and can be folded to the designed minimum storage size space, and the structural weight and complexity are not increased.

    本发明公开了一种机臂关节止松及折叠结构,包括中心盘悬臂组件、机臂折叠组件和螺纹套组件。本发明通过螺纹套件与中心盘内件相紧配,螺纹套件压紧机臂内件,从而使机臂折叠组件与中心盘悬臂组件实现稳固连接,同时,设计的螺纹套止松组件能对螺纹套组件进行止松,从而增加无人机飞行的安全性和可靠性。本发明通过机臂折叠组件与折叠转接件连接的第一转轴销钉和第二转轴销钉的两次绕轴旋转,使机臂折叠组件在折叠时,即不与无人机其它组件干涉,又能折叠到设计的最小收纳尺寸空间而不增加结构重量和复杂度。
