An automatic sunshade stand, referring to FIGS. 1 to 4 , includes a support rod 1 and an umbrella rib 2, the umbrella rib 2 includes a first frame 21 and a second frame 22 distributed up and down, and the second frame 22 The free ends are respectively hinged to the first frame 21, and the first frame 21 is provided with a limiter 211 for limiting the distance between the first frame 21 and the second frame 22;

A first support rod 31 is connected between the support rod 1 and the first frame 21 , and a second support rod 32 is hinged between the first support rod 31 and the second frame 22 . A third support rod 33 is hinged between the support rod 31 and the support rod 1 , and an adjustment box 4 mounted on the support rod 1 is hinged at one end of the first support rod 31 away from the umbrella rib 2 . The adjustment box 4 A reel 41 is rotatably connected inside, and a traction rope 42 is wound on the reel 41. The free end of the traction rope 42 passes through the center of the first frame 21 and the second frame 22 along the first pole 31. The center is fixedly connected, and a first driving part 43 for driving and positioning the reel 41 is installed in the adjusting box 4 .

When the sunshade needs to be folded, the user activates the first driving part 43, the first driving part 43 drives the reel 41 to pay off the wire, and under the gravity of the second frame 22, the first frame 21 and the second frame are elongated The vertical spacing between 22 shortens the horizontal spacing, thereby achieving the purpose of shrinking the sunshade;

When the parasol needs to be unfolded, the user activates the first driving part 43, and the first driving part 43 drives the reel 41 to take up the wire, thereby shortening the vertical distance between the first frame 21 and the second frame 22 and lengthening the horizontal direction distance, and then achieve the purpose of unfolding the sunshade, when the center of the second frame 22 abuts on the limiting member 211, the sunshade reaches the limit unfolding state;

Therefore, the sunshade can be automatically retracted.

In this embodiment, the abutting member is a riser installed at the center of the first frame 21 . In order to facilitate accurate contact between the center of the second frame 22 and the riser, a positioning column 221 is provided at the center of the second frame 22, and the upper end of the positioning column 221 is tapered, so as to be more easily inserted into the riser.

Specifically, a first differential 44 is installed on the inner wall of the reel 41 and the adjustment box 4 , and a first handle 45 is installed at one end of the first differential 44 away from the reel 41 . The first handle 45 is located outside the adjustment box 4 .
