The invention discloses a lockable folding paddle which comprises a paddle body and a paddle clamp; the paddle body is rotationally arranged on the paddle clamp, and the paddle body can be unfolded orfolded relative to the paddle clamp; the lockable folding paddle also comprises a locking bolt assembly which is used for limiting the paddle to rotate relative to the paddle clamp after the paddle is unfolded relative to the paddle clamp. According to the folding paddle, abrasion between the paddle blades and the paddle clamp can be reduced, the service life of the folding paddle is prolonged, and the resonance problem caused by large-size polymer paddle blades is reduced.
本发明公开了一种可锁定的折叠桨叶,包括桨叶和桨夹,所述桨叶转动设置于桨夹上,所述桨叶相对于所述桨夹能够展开或折叠;还包括锁定插销组件,所述锁定插销组件用于在桨叶相对于桨夹展开后限制桨叶相对于桨夹产生相对转动。本发明能够减少桨叶与桨夹之间的磨损,增加折叠桨的使用寿命,并降低大尺寸聚合物桨叶带来共振问题。
