The invention discloses a multifunctional paddling board which comprises a paddling board body, a sliding groove is formed in the paddling board body, two floating blocks are arranged on the paddling board body in a bilateral symmetry mode, a cylinder is arranged on each floating block, a backrest device is arranged in the sliding groove, each floating block is provided with a rotating device, and a paddling device is arranged on each cylinder. By arranging the paddling devices, in the rotating process of the paddle rod, the paddling plates revolve around the cylinders and rotate at the same time, so that the paddling plates are always in a vertical state with the advancing direction in the advancing process of the paddle plates, the situation that part of force of an operator is counteracted in the paddling process of the two paddling plates is avoided, the arm strength of the operator is completely converted into power for advancing of the paddle plates, and idle work is avoided; and meanwhile, in the automatic reset process of the rotating device, the paddling plates and the water surface are in a parallel state in the height direction, so that resistance is reduced in the reset process of the paddling plates and the paddling plates are rapidly reset.
本发明公开了一种多功能划桨板,包括桨板,所述桨板内设有滑槽,所述桨板上左右对称设有两个浮块,每个所述浮块上分别设有圆柱,所述滑槽内设有靠背装置,每个所述浮块分别设有转动装置,每个所述圆柱上分别设有划水装置,本发明通过设置划水装置使得桨杆在转动过程中,滑水板围绕圆柱公转的同时,自身发生自转,使得滑水板在桨板前进的过程中始终与前进方向呈现垂直状态,避免操作者的一部分力使得两个滑水板在划水的过程中相互抵消,使得操作者的臂力,全部转化成桨板前进的动力,避免无用功的产生,同时在转动装置自动复位的过程中,滑水板与水面在高度上成平行状态,使得滑水板复位的过程中减少阻力,使其快速复位。
