In the technical field of curtains, this invention discloses an outdoor rolling curtain, comprising an upper beam (1) fixed on the window frame and a rotating shaft (2); the lower end of the upper beam (1) is available with a horizontal groove (11); the horizontal groove (11) is fixedly connected with a curtain (3); the other end of the curtain (3) is fixedly connected to the rotating shaft (2); a curtain string (41) is installed in the horizontal groove (11); the horizontal groove (11) is further equipped with a drawstring (4) to pull the curtain string (41); a chain pulley (22) is installed at each end of the rotating shaft (2); the curtain string (41) is wound around the two chain pulleys (22) respectively. By disposing the rotating shaft below in this utility model, the weight of the rotating shaft can prevent the curtain from being greatly disturbed due to the influence of the external airflow when the curtain is lowered; by disposing the rotating shaft below, there is no need to reserve a winding space at the upper beam in comparison with the winding mode of the upper fixed shaft, thus making the fixation of the upper beam more firmly.
