The invention provides a barrel type launching unmanned aerial vehicle rapid unfolding locking type propeller and a barrel type launching unmanned aerial vehicle. The propeller comprises a propeller clamp and two blades connected to the two ends, and the propeller clamp comprises a propeller clamp seat, two torsional springs, a first rotating shaft and a second rotating shaft. The torsional spring penetrates through the first rotating shaft and is mounted in the paddle holder, one end of the torsional spring is hooked on the paddle holder, and the other end of the torsional spring is hooked on the paddle. The paddle can rotate around the second rotating shaft relative to the paddle clamping seat under the action of the torsion spring and automatically move from a folding position to an unfolding position, the paddle is parallel to the fuselage of the unmanned aerial vehicle at the folding position, and the paddle is perpendicular to the fuselage at the unfolding position. And the paddle clamp seat is provided with a stop part, and the paddle is limited after being unfolded in place so as to prevent the paddle from unfolding and rotating under the influence of airflow. The paddle does not shake randomly during transportation of the unmanned aerial vehicle; during launching, the blades can be quickly unfolded under the restoring force of the torsional spring; after being unfolded, the paddles are blocked by the blocking parts and cannot rotate and shake in the unfolding direction due to the influence of airflow, and the flight reliability is guaranteed.
本发明提供了筒式发射无人机快速展开锁紧式螺旋桨及筒式发射无人机。螺旋桨包括浆夹和连在两端的两片桨叶,浆夹包括浆夹座以及两个扭簧、第一转轴和第二转轴。扭簧穿过第一转轴安装在浆夹座内,扭簧一端钩接在浆夹座上,另一端钩接在桨叶上。桨叶能在扭簧的作用下相对于浆夹座围绕第二转轴旋转从收起位置自动运动至展开位置,在收起位置,桨叶与无人机的机身平行,在展开位置,桨叶与机身垂直。浆夹座设有止挡部,在桨叶展开到位后对桨叶限位以防止桨叶在气流的影响下进行展开旋转运动。无人机运输中桨叶不会随意晃动;发射时,桨叶可在扭簧恢复力下快速展开;桨叶展开后被止挡部阻挡,不会因气流影响在展开方向上旋转晃动,保证飞行可靠性。
