[0022] like Figures 1 to 9As shown, this utility model discloses a sunshade umbrella, comprising a base 1, a column 2, a sliding sleeve 3, a cross arm 5, and an umbrella frame assembly 9; the base 1 is placed on the ground; wherein, the lower end of the column 2 is fixed to the base 1; the sliding sleeve 3 can slide up and down on the column 2 and can be positioned on the column 2; one end of the cross arm 5 is hinged to the sliding sleeve 3, and the other end of the cross arm 5 is hinged to the umbrella frame assembly 9; it also includes a first connecting rod 6, a second connecting rod 7, and a telescopic rod 8; one end of the second connecting rod 7 is hinged to the fixed sleeve 4 or the column 2, and the other end is hinged to the first connecting rod 6; one end of the first connecting rod 6 is hinged to the cross arm 5, and the other end is hinged to the telescopic rod 8; the telescopic rod 8 is slidably installed into the internal cavity 10 of the column 2 (it is conceivable that a sleeve connection is also an implementation method); the up and down sliding of the sliding sleeve 3 is controlled by the linkage of the first connecting rod 6, the second connecting rod 7, and the telescopic rod 8 to control the angle of the cross arm 5.

[0023] It is worth mentioning that one end of the second connecting rod 7 is hinged to the fixing sleeve 4 or the column 2. In this embodiment, for ease of installation, one end of the second connecting rod 7 is hinged to the fixing sleeve 4. The fixing sleeve 4 is fixedly installed on the column 2 with screws; also, the fixing sleeve 4 is approximately U-shaped. It is conceivable that one end of the second connecting rod 7 could also be directly hinged to the column 2.

[0024] Furthermore, the umbrella frame component 9 is existing technology and is not an invention point, so it will not be elaborated further.

[0025] To facilitate the smooth up-and-down sliding of the telescopic rod 8, a first roller assembly 11 is provided at the lower end of the telescopic rod 8; the first roller assembly 11 includes a plurality of first rollers 1101 and a first roller seat 1102, the first roller seat 1102 is fixedly installed at the lower end of the telescopic rod 8, and the plurality of first rollers 1101 are rotatably disposed within the first roller seat 1102.

[0026] Furthermore, to facilitate the hinged rotation of the telescopic rod 8 and the first connecting rod 6, a hinge assembly 14 is provided at the upper end of the telescopic rod 8 (it is conceivable that the telescopic rod 8 and the first connecting rod 6 could also be directly hinged). The hinge assembly 14 includes a connecting sleeve 1401 and a top cover 1402.
