The outdoor sunshade umbrella currently used is usually divided into hanging umbrellas and center column umbrellas due to the setting position of the umbrella surface. The hanging umbrella has a good use effect because the umbrella surface adopts a lateral suspension structure and has a larger area space at the bottom. The Roman umbrella is the most powerful one in outdoor sunshade umbrellas, which can rotate one circle in the horizontal direction and can be inclined by 90 degrees in the vertical direction. Using the Roman umbrella for sunshade is the most creative and leisure sunshade way in the Chinese market. The area under the umbrella is wide and outdoor furniture can be placed at will; the direction of the umbrella surface can be freely rotated and the sunlight can be blocked at will.

[0003] The Roman umbrella is controlled to rotate and lift by the handle, which is labor-saving and worry-free. In order to facilitate the winding of the rope, it is sometimes necessary to adjust the position of the handle. At present, the handle of the sunshade umbrella is generally arranged on the handrail device, and the position of the handle can be adjusted by moving the handrail device. Among them, the handrail device moves up and down along the umbrella column, which can adjust the inclination angle of the umbrella surface and also facilitates the subsequent opening and closing operation of the umbrella surface.

[0005] In addition, the publication number CN216363986U provides a handle structure of a Roman umbrella, which belongs to the technical field of Roman umbrellas. It solves the technical problem of poor service life of the existing handle structure of the Roman umbrella. The handle structure of the Roman umbrella includes a handle part and a movable pressing piece. The handle part has a vertical through hole. A plug pin is arranged horizontally in the handle part and is fixedly connected with the pressing piece. The outer periphery of the plug pin is sleeved with a return spring, one end of which can push the plug pin into the tube hole. The handle part is provided with a ring-shaped bowl-shaped positioning piece, which is sleeved on the outer periphery of the plug pin. The other end of the return spring is in abutment with the inner cavity bottom surface of the positioning piece. When the pressing piece drives the plug pin to retract, it can be limited and abutted with the open end of the positioning piece and make the return spring compressed in the inner cavity of the positioning piece.

[0006] The Roman umbrella opening and closing umbrella structure, most of which adopts the open number US20100051074A1, the disclosure of an outdoor umbrella, comprising: umbrella column, with a lower end for supporting the lower part and an upwardly extending upper end; Sliding member (handrail assembly) associated with the umbrella column, which can be selectively moved between the upper and lower positions of the umbrella column; Locking device for releasably fixing the sliding member to the main rod at a selected position along the umbrella column; Umbrella canopy with a central region; Arm (diagonal strut) associated with the central region and extending radially from the central region to the outer end operatively associated with the sliding member; support having a first end pivotally connected to the upper part of the rod above the sliding member and a second end pivotally connected to the arm; winding mechanism having a winding reel hub around which a wire (umbrella rope) can be wound, the winding reel hub (umbrella rope wheel) being mounted to the sliding member and moving therewith; a wire having a first end wound around the winding reel hub, a second end extending from the winding reel hub along the arm to the middle part of the umbrella cover, and a second end engaging the umbrella cover; wherein the rotation of the winding reel hub tightens or loosens the rope according to the direction of rotation of the winding reel hub, and wherein the operation of the winding mechanism opens and closes the umbrella canopy in response to the movement of the rope; wherein the angle of the umbrella canopy relative to the main rod can be controlled by moving the sliding member along the main rod.

[0007] As the main export country of domestic Roman umbrella, there are many Roman umbrellas limited by the protection range of the above-mentioned patent, which requires the payment of expensive patent fees. For this reason, many existing Roman umbrellas adopt other opening and closing umbrella structures, such as setting the crank structure with the umbrella column, such as the announcement number CN216983907U, a Roman umbrella with adjustable opening and closing angle of crank, including an umbrella column and an umbrella disc assembly, the umbrella disc assembly includes an upper umbrella disc and a lower umbrella disc, the umbrella column is provided with a sliding block, the upper umbrella disc is provided with a connecting rod and a pull rod, the end of the connecting rod is hingedly connected to the sliding block, the pull rod is hingedly connected to the top end of the umbrella column, and the other end is hingedly connected to the connecting rod, the umbrella column is provided with an umbrella opening assembly, the umbrella opening assembly includes an opening and closing crank and an umbrella rope arranged in the inner cavity of the umbrella column, one end of the umbrella rope is fixedly connected to the opening and closing crank, the other end extends to the upper end of the umbrella column and is connected to the lower umbrella disc in sequence after passing through the pull rod and the connecting rod, and the umbrella rope is driven by the opening and closing crank.
