Abstract

An automatic opening and closing umbrella easy to close comprises a middle rod (1), an umbrella head (3), a bullet (51), an umbrella opening spring (52), an ejector rod (53), a first pull line (54) and a second pull line (55). A fist pulley (61) and a second pulley (62) are respectively arranged at the top of a middle tube (12) of the middle rod (1) and an upper nest (21). The umbrella opening spring (52) is arranged in an inner tube (11) and the middle tube (12). One end of the first pull line (54) is connected with the bullet (51), and the other end of the first pull line (54) winds through the first pulley (61) and then is connected with the bottom of the ejector rod (53). The top of the ejector rod (53) abuts against the upper nest (21). One end of the second pull line (55) is connected with the top of the middle tube (12), and the other end of the second pull line (55) winds through the second pulley (62) and then is connected with a lower nest (22). When the automatic opening and closing umbrella is closed, a partial of a tube body of the middle rod can be folded at the same time so that force for closing the umbrella is greatly reduced, utilization is convenient, structure is simple, and cost is low.
