The invention discloses an undercarriage anti-loosening device and a multi-rotor unmanned aerial vehicle. The undercarriage anti-loosening device comprises an undercarriage fixing seat assembly used for providing a mounting carrier of an undercarriage rod, a switching assembly arranged at the end of the undercarriage and used for being matched with the undercarriage fixing seat assembly to achieve rapid connection between the undercarriage and the undercarriage fixing seat assembly, and a locking assembly arranged on the undercarriage fixing seat assembly and used for locking the undercarriage rod. The anti-loosening structure is used for being matched with the switching assembly to prevent the undercarriage and the undercarriage fixing seat assembly from loosening in the flight process; and the limiting assembly is arranged on the anti-loosening structure and used for limiting displacement of the anti-loosening structure. The whole device is simple in form, compact in structure, light in weight, stable and reliable, the undercarriage can be rapidly detached, and the space utilization rate of the carrying tool is increased. And a push-press unlocking and automatic resetting form is adopted, so that the operation is simple, and the service life is long. And a redundancy design is adopted, so that the undercarriage is not loosened in the flight process of the aircraft.

    本发明公开了一种起落架防松脱装置及多旋翼无人飞行器。该起落架防松脱装置包括:用于提供起落架杆的安装载体的起落架固定座组件,设置在起落架的端部,用于与起落架固定座组件配合实现起落架和起落架固定座组件之间的快速连接的转接组件,设置在所述起落架固定座组件上,用于与转接组件配合防止在飞行过程中起落架和起落架固定座组件松脱的防松脱结构和设置在所述防松脱结构上,用于对防松脱结构的位移进行限位的限位组件。本发明的整个装置形式简单、结构紧凑、重量轻巧、稳定可靠,起落架可快速拆下,提高携行具空间利用率。采用推按解锁自动复位的形式,操作简单,使用寿命长。采用余度设计,保证了飞机在飞行过程中起落架不松脱。
