The invention discloses a paddle anti-rotation fixing structure which comprises a paddle shell, the paddle shell is provided with a paddle sleeve, the paddle anti-rotation fixing structure further comprises a clamping sleeve, a paddle sleeve blocking cover and a screw, a paddle root is installed in the paddle sleeve through the clamping sleeve and the paddle sleeve blocking cover which are sequentially arranged on the paddle root in a sleeving mode, the outer end of the clamping sleeve is provided with an outer conical surface, and the inner end of the paddle sleeve blocking cover is provided with an inner conical surface corresponding to the outer conical surface; the oar sleeve blocking cover is fixedly connected with the oar sleeve end face through a screw, so that the outer conical surface is tightly attached to the inner conical surface. The outer conical surface of the clamping sleeve is matched with the inner conical surface of the oar sleeve blocking cover, the oar sleeve blocking cover moves towards the inner side of the oar sleeve along with screwing of the screw, the clamping sleeve gradually tightly holds the oar root, and the matching position of the clamping sleeve and the oar root, the matching position of the oar sleeve and the oar sleeve blocking cover and the matching position of the oar sleeve blocking cover and the conical surface of the clamping sleeve are tightly held due to friction force. It is guaranteed that the blades do not rotate along the axes of the blades in the rotating process of the propeller, and fixing is reliable and stable.

    本发明公开了一种桨叶防转固定结构,包括浆壳,浆壳具有桨袖,还包括卡紧套、桨袖挡盖和螺钉,桨叶叶根通过依次套合在其上的卡紧套和桨袖挡盖安装在桨袖内,其中卡紧套外端具有外锥面,桨袖挡盖内端具有与外锥面相对应的内锥面;桨袖挡盖通过螺钉与桨袖端面紧固连接,使得外锥面与内锥面紧密贴合。本发明卡紧套的外锥面与桨袖挡盖的内锥面配合,随着螺钉拧紧,桨袖挡盖向桨袖内侧移动,卡紧套逐渐抱紧桨叶叶根,卡紧套与桨叶叶根配合处、桨袖与桨袖挡盖配合处及桨袖挡盖和卡紧套锥面配合处因摩擦力抱紧,保证了在螺旋桨旋转过程中桨叶不发生沿桨叶轴线的转动,固定可靠稳定。
