The invention discloses a self-locking buckle, a folding wing and a cylindrical folding wing unmanned aerial vehicle. Comprising an elastic clamping hook (401) and a sliding slope (402), a clamping groove (403) is formed in the bottom face of the elastic clamping hook (401), the depth of the clamping groove (403) is gradually increased in the length direction of the elastic clamping hook (401), the head end of the bottom face of the clamping groove (403) is connected with the bottom face of the elastic clamping hook (401), and the tail end of the bottom face of the clamping groove (403) is connected with the bottom face of the elastic clamping hook (401) through a vertical straight face A (404); the whole slope (402) is a right-angle triangular block, the top face of the slope (402) is an inclined face of the right-angle triangular block, the tail end of the slope (402) is a vertical straight face B (405) of the right-angle triangular block, and the bottom face of the slope (402) is a flat straight face (406) of the right-angle triangular block. When the self-locking buckle is buckled, the bottom face of the clamping groove (403) and the top face of the sliding slope (402) are oppositely combined, and the vertical straight face A (404) and the vertical straight face B (405) are oppositely combined. The invention has the characteristics of small storage space, simple folding mechanism and capability of effectively improving the aerodynamic characteristics of the wings.

    本发明公开了一种自锁卡扣、折叠机翼、筒式折叠翼无人机。包括弹性卡勾(401)和滑坡(402),弹性卡勾(401)底面设有卡槽(403),卡槽(403)深度沿弹性卡勾(401)长度方向递增,卡槽(403)底面的头端与弹性卡勾(401)底面连接,卡槽(403)底面的尾端经立直面A(404)与弹性卡勾(401)底面连接;滑坡(402)整体呈直角三角块,滑坡(402)顶面为直角三角块的斜面,尾端为直角三角块的立直面B(405),底面为直角三角块的平直面(406);自锁卡扣扣合时,卡槽(403)底面与滑坡(402)顶面对合,立直面A(404)与立直面B(405)对合。本发明具有收纳空间小、折叠机构简单、能有效改善机翼气动特性的特点。
