Abstract

The utility model provides a novel rope winding mechanism including a rocking handle assembly installed on an umbrella rod. The rocking handle assembly includes a rotary shaft arranged in the umbrella rod transversely in a penetrating manner and a rocking handle disposed outside the umbrella rod and capable of driving the rotary shaft to rotate. The novel rope winding mechanism is characterized in that the rotary shaft is sleeved with a bobbin capable of rotating along with the rotary shaft synchronously; a first radial annular raised wall is formed on a side of the bobbin adjacent to the rocking handle; a second radial annular raised wall is formed on a side of the bobbin away from the rocking handle; and a umbrella rope coils on the bobbin and is limited between the first radial annular raised wall and the second radial annular raised wall. Compared with prior art, since the rotary shaft of the rocking handle assembly is sleeved with the bobbin rotating synchronously along with the rotary shaft and the umbrella rope coiled on the bobbin is limited between the first radial annular raised wall and the second radial annular raised wall, the umbrella rope does not contact neither the surface of the umbrella rod or the rotary shaft directly in an umbrella closing process and an umbrella opening process. Therefore, abrasion degree of the umbrella rope is reduced and service lifetime of the umbrella rope is prolonged.
