DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figures 1-6 As shown, this embodiment provides an improved arc-top umbrella with stable support, including a support rod 1, 12 umbrella ribs 2, a sliding sleeve 3 and an umbrella surface.

[0022] The 12 umbrella ribs 2 are arranged at intervals along the axis of the support rod 1. The umbrella surface is used to cover the top of the umbrella ribs 2. The sliding sleeve 3 is sleeved on the support rod 1 and slidably connected. The umbrella ribs 2 include a first arc-shaped strip 21 and a first connecting strip 22. The sliding sleeve 3 is sleeved on the support rod 1 and slidably connected. The sliding sleeve 3 adopts an automatic opening mechanism commonly used in existing straight-pole umbrellas, and is composed of an upper seat body, a lower seat body, and a spring connected to the upper seat body and the lower seat body. One end of the first arc-shaped strip 21 is rotatably connected to the upper end of the support rod 1, one end of the first connecting strip 22 is hinged to the sliding sleeve 3, and the other end of the first connecting strip 22 intersects with the first arc-shaped strip 21. The two first arc-shaped strips 21 are connected to the first connecting strip 22. 1 is provided with a stabilizing plate 23, which is hinged to one of the first arc strips 21. Specifically, a damping ring is provided at the hinge. The stabilizing plate 23 will move only when it is manually moved. The other first arc strip 21 has a plug hole 24, and the stabilizing plate 23 is inserted into the plug hole 24. Specifically, the first arc strip 21 has a long strip receiving groove, and the stabilizing plate 23 is located in the long strip receiving groove. One end of the stabilizing rod is hinged to the two side walls of the long strip receiving groove. The plug hole 24 is located on the outward side of the long strip receiving groove. The plug hole 24 is obliquely arranged. The end of the stabilizing plate 23 has an insert block 231, and the insert block 231 is adapted to the plug hole 24. There are 12 stabilizing plates 23, and stabilizing rods are provided between adjacent first arc strips 21.

[0023] When the weather is bad, the stabilizing rod is moved to bring the inserting block 231 of the stabilizing rod close to the insertion hole 24 , and then the first arc-shaped bar 21 is moved to elastically deform the first arc-shaped bar 21 so that the inserting block 231 is inserted into the insertion hole 24 .

[0024] Preferably, the number of the stabilizing plates 23 may also be set to 6.

[0025] The support rod 1 includes a accommodating portion 11 and a rotating portion 12. The accommodating portion 11 has a first chamber 111 at the lower end, and a rotating channel is provided below the first chamber 111. A rotating rod 121 is formed at the upper end of the rotating portion 12, and the rotating rod 121 passes through the rotating channel. Specifically, a limiting ring 1231 groove is provided in the rotating channel, and a limiting clamping ring 1211 is provided around the rotating rod 121. The limiting ring 1231 groove and the limiting clamping ring 1211 are adapted to each other. A rotating block 122 is provided at the end of the rotating rod 121. The horizontal cross-section of the rotating block 122 is elliptical. A clearance gap is provided on one side of the lower end of the first chamber 111. The circumference of the sliding sleeve 3 is provided with a locking gap 31. The locking gap 31 corresponds to the clearance gap. A push-up column 123 is provided at the clearance gap. One end of the push-up column 123 is pressed against the circumference of the rotating block 122. A limiting ring 1231 is formed on the circumference of the inner end of the push-up column 123. A return spring 124 is provided between the limiting ring 1231 and the inner wall of the first chamber 111. The return spring 124 is sleeved on the circumference of the push-up column 123. By rotating the rotating part 12, the rotating block 122 is rotated. Since the horizontal cross-section of the rotating block 122 is elliptical, when the push-up column 123 moves from one quadrant point to another quadrant point, the push-up column 123 will move (eject or shrink).
