The utility model provides a spar connecting joint with a locking function. The spar connecting joint comprises a fixed section spar supporting seat, a movable section spar supporting seat, a lockingpipe clamp, a locking rotating rod, a locking rocker and a rocker lock catch assembly. The wing spar supporting seats are respectively arranged in the fixed section wing and the movable section wing;the main wing spar and the auxiliary wing spar are fixedly connected with the wing spar supporting seats in the fixed section wing; a locking pipe clamp is arranged on the wing spar supporting seat inthe movable section wing, and a rocker lock catch assembly is arranged on the fixed section wing spar supporting seat; the locking rotating rod is arranged on the locking pipe clamp, and the lockingrocker is arranged on the locking rotating rod. The locking rocker is rotated to drive the locking rotating rod, the locking pipe clamp can be pressed and locked, and the movable section and the fixedsection wing are locked and fastened. After the locking rocker is locked, the locking rotating rod can be prevented from loosening and rotating during flight, and firm locking between the movable section wing and the fixed section wing can be kept. The spar connecting joint has the advantages of light weight, small size, high connecting speed, simplicity in operation, reliability in connection and small influence on the flight performance of the unmanned aerial vehicle.

本专利提供一种带有锁定功能的翼梁连接接头。包括固定段翼梁支撑座，活动段翼梁支撑座，锁定管夹，锁定转杆，锁定摇杆及摇杆锁扣组件。翼梁支撑座分别安置在固定段机翼与活动段机翼内，主、辅翼梁与固定段机翼内的翼梁支座固定连接；在活动段机翼内的翼梁支撑座上设有锁定管夹，固定段翼梁支撑座上设有摇杆锁扣组件；锁定转杆安置在锁定管夹上，锁定摇杆安置在锁定转杆上。转动锁定摇杆带动锁定转杆，可将锁定管夹压紧锁定，将活动段与固定段机翼锁定紧固。锁定摇杆锁定后能防止锁定转杆在飞行时松动转动，能保持活动段机翼与固定段机翼间的牢固锁定。本发明具有质量轻、体积小、连接速度快、操作简单、连接可靠，对无人机飞行性能影响小的优点。
