Abstract

The utility model relates to a non-skid uncoupling apparatus of sunshade umbrella, comprising a cord arranged on a cord pulley on rack post and a wound on an axis to control umbrella fold and unfold. Meanwhile, the pulley connects with scroll bar provided with friction disk through thread and makes the friction disk deploy inside the concave support slot of ratchet wheel. Moreover, the pulley activates the flexible module utilized to push ratchet outwards, which should closely connect with friction disc. Moreover, the ratchet wheel realizes unidirectional obstruction with the help of a flexible shrinkable barrier module. External end of scroll bar is configured with a bearing surface, which can be fixed on the sliding ball on rack post. Therefore, during clockwise rotation, the scroll bar fastens the rope pulley and ratchet wheel together, thus driving the rope pulley to coil and unfolding the umbrella. Obstruction of ratchet wheel through barrier module will prevent reversal of rope pulley.
