The invention discloses an unmanned aerial vehicle empennage quick-dismounting device with taper. The unmanned aerial vehicle empennage quick-dismounting device comprises a front supporting rod connector, a clamping pin, a clamping pin fixing ring, a torsional spring, a positioning pin, a rear supporting rod connector and a positioning pin fixing ring. One end of the front supporting rod connectoris provided with a conical concave face, the rear supporting rod connector is fixedly provided with a conical convex face, and the conical concave face and the conical convex face are in conical facefit. The locking torque of the torsional spring is adjustable, and the adaptability and safety of a quick-dismounting piece to various requirements are improved; the locking torque is amplified through a small-angle chute, and self-locking of the device is achieved; and the conical faces of the front connector and the rear connector are in contact to eliminate matched vacancy of two parts and amplify the fastening force, a quick-dismounting mechanism of a composite wing unmanned aerial vehicle is not likely to loosen in a flying process, flying is safer, the device can be quickly dismounted by rotating the clamping pin fixing ring, and therefore, quick dismounting of an unmanned aerial vehicle empennage is achieved. The unmanned aerial vehicle dismounting time can be greatly shortened.
本发明公开了一种带锥度的无人机尾翼快拆装置,无人机尾翼快拆装置包括前撑杆接头、卡紧销、卡紧销固定环、扭簧、定位销、后撑杆接头和定位销固定环,前撑杆接头的一端锥形凹面,后撑杆接头固定设有锥形凸面,锥形凹面与锥形凸面之间锥形面配合。本发明通过扭簧锁紧力矩可调,增加了快拆件对各种要求的适配性和安全性;通过小角度斜槽放大锁紧力矩并实现本装置的自锁;通过前后接头锥形面接触消除两个零件配合的虚位并放大紧固力,复合翼无人机在飞行过程中快拆机构不容易松脱,飞行更安全,通过旋转卡紧销固定环可对本装置进行快速的拆装,从而实现无人机尾翼的快速拆装。可大幅缩短无人机拆装时间。
