The invention belongs to the technical field of propellers, and particularly relates to a connecting structure for a propeller and the propeller. The connecting structure comprises a paddle root shaft and a paddle, a positioning groove is formed in the end face of the paddle root shaft, a positioning block is arranged at the root of the paddle, and the positioning block is connected with the positioning groove in a clamped mode. According to the connecting structure, the positioning groove is formed in the end face of the paddle root shaft, the positioning block matched with the positioning groove in shape and size is arranged at the root of the paddle, the positioning block is inserted into the positioning groove, and after the positioning block completely enters the positioning groove, mechanical interlocking (the connecting structure during locking) is formed between the positioning block and the positioning groove; due to the accurate matching between the positioning groove and the positioning block, the interlocking connection ensures the firm connection between the paddle and the paddle root shaft.

    本发明属于螺旋桨技术领域,具体涉及一种用于螺旋桨的连接结构及螺旋桨。连接结构包括浆根轴和桨叶,其中浆根轴的端面上开设有定位槽,桨叶的根部设有定位块,定位块与定位槽相卡接。根据本发明的连接结构,在浆根轴的端面上设有定位槽,桨叶的根部设有与定位槽形状和尺寸相匹配的定位块,让定位块插入到定位槽中,当定位块完全进入定位槽后,定位块与定位槽之间形成机械互锁(锁定时的连接结构),由于定位槽和定位块之间的精确配合,这种互锁连接确保了桨叶与桨根轴之间的牢固连接。
