A curved pipe umbrella with a structure for adjusting an inclination angle of an umbrella body includes a curved pipe umbrella column. The curved pipe umbrella column includes a first curved pipe umbrella column and a second curved pipe umbrella column. One end of the second curved pipe umbrella column is embedded into an upper inner cavity of the first curved pipe umbrella column and the other end thereof extends outward to match with the umbrella body. A pole bracket is arranged in the umbrella body and matches with the first curved pipe umbrella column through a sliding seat. The curved pipe umbrella further includes an operating mechanism configured to drive the second curved pipe umbrella column. When the operating mechanism drives the second curved pipe umbrella column to stretch and retract, a sliding seat can move along different positions of the first curved pipe umbrella column.

This invention discloses a cantilever umbrella with duo-arc tubes in a sliding-sleeve configuration, which includes: a base support for the arched tubes, a lower arched tube, an upper arched tube, a main canopy frame and a handle assembly. The upper arched tube is slidably connected with the lower arched tube through the handle assembly; the umbrella's main canopy frame is installed at the distal end of the upper arched tube through a canopy base junction; a mounting channel cooperating with the upper arched tube is provided on the inner surface of said lower arched tube-said mounting channel, once mated with the upper arched tube, leads to a semi-covered structure over the upper arched tube; and a winding wheel is provided to control the open and close of the main canopy frame.
