[0046] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0047] like Figures 6 to 12 As shown, the utility model discloses a multi-fold anti-flip umbrella rib, which includes an inner main bone 1, an inner branch bone 2, a middle main bone 3, a connecting bone 4, an outer main bone 5 and a traction bone 6; wherein, the middle main bone 3 includes an inner connecting seat 31, an outer connecting seat 32, and a middle bone 33 whose inner and outer ends are respectively connected to the inner connecting seat 31 and the outer connecting seat 32, the outer end of the inner main bone 1 is pivotally connected to the middle part of the inner connecting seat 31, the inner end of the inner branch bone 2 is pivotally connected to the middle part of the inner main bone 1, the inner end of the connecting bone 4 is pivotally connected to the proximal inner end of the inner branch bone 2, and the outer end of the connecting bone 4 is pivotally connected to the inner end of the inner connecting seat 31, the outer main bone 5 includes a pivot seat 51 and an outer bone 52 whose inner end is connected to the pivot seat 51, the middle part of the pivot seat 51 is pivotally connected to the outer end of the outer connecting seat 32, the inner end of the traction bone 6 is pivotally connected to the proximal inner end of the inner main bone 1, and the outer end of the traction bone 6 is pivotally connected to the inner end of the pivot seat 51.

[0048] In the embodiment of the present invention, the cross section of the middle bone 33 is in the shape of an I (see Figure 11As shown in the figure, the middle bone 33 includes an upper bone 331, a lower bone 332 and a middle bone 333 which are integrally formed. The upper and lower sides of the middle bone 333 are respectively connected to the upper bone 331 and the lower bone 332, and the width of the middle bone 333 is smaller than the width of the upper bone 331 and the lower bone 332. The structure of the middle bone 33 of the present invention is arranged in this way, so that the middle bone 33 is not easy to bend and twist. In this way, when a multi-fold umbrella adopting the multi-fold anti-flip ribs of the present invention is used and encounters strong winds, the middle bone 33 is not easy to be deformed and can effectively pull the outer main bone 5, thereby avoiding the problem of the multi-fold umbrella flipping.

[0049] In the embodiment of the present invention, the inner and outer ends of the center bone 33 are respectively inserted into the inner and outer connecting seats 31, 32, thereby improving the connection stability of the center bone 33 to the inner and outer connecting seats 31, 32. The inner and outer ends of the center bone 33 can be respectively bonded to the inner and outer connecting seats 31, 32, thereby simplifying the connection of the center bone 33 to the inner and outer connecting seats 31, 32. Of course, the center bone 33 can also be connected to the inner and outer connecting seats 31, 32 using other connection methods, such as riveting, welding, or integral molding.

[0051] In the embodiment of the present invention, the upper side of the outer connecting seat 32 is provided with a limit portion 321 for the inner end of the pivot seat 51 to abut against; when the multi-fold anti-turnover ribs are fully unfolded (see Figure 6 (As shown in the figure), the inner end of the pivot seat 51 abuts against the limiting portion 321 of the outer connecting seat 32, limiting the rotation of the pivot seat 51, thereby preventing the pivot seat 51 from excessively rotating and causing the multi-fold umbrella to flip over. The limiting portion 321 may be provided with a limiting groove 3211 for the inner end of the pivot seat 51 to be inserted into. When the multi-fold anti-flip ribs are fully deployed, the inner end of the pivot seat 51 abuts against the limiting groove 3211 inserted into the limiting portion 321, limiting the pivot seat 51 from swinging, thereby preventing the pivot seat 51 from swinging out of the limiting portion 321.

[0052] In the embodiment of the present invention, the inner end of the outer frame 52 is inserted into the pivot seat 51, thereby improving the connection stability between the outer frame 52 and the pivot seat 51. The inner end of the outer frame 52 and the pivot seat 51 can be bonded, which simplifies the connection between the outer frame 52 and the pivot seat 51. Of course, the outer frame 52 and the pivot seat 51 can also be connected by other connection methods, such as riveting, welding, integral molding, etc.

[0053] In an embodiment of the present invention, the connecting bone 4 is an integrally stamped structure with a U-shaped cross-section. This provides high strength and resists tensile deformation, ensuring that the connecting bone 4 exerts a pulling force on the main bone 3, thereby preventing the umbrella from flipping when folding multiple folds. The connecting bone 4 may include two opposing first connecting bone pieces 41 and a second connecting bone piece 42 connecting the two first connecting bone pieces 41. The two first connecting bone pieces 41 and the second connecting bone piece 42 are integrally stamped and formed.

[0054] In an embodiment of the present invention, the inner main rib 1 is also an integrally stamped structure, and the cross-section of the inner main rib 1 is "U"-shaped. This provides high strength and resists tensile deformation, ensuring the stability of the multi-fold anti-flip rib. The inner main rib 1 may include two opposing first inner main rib pieces 11 and a second inner main rib piece 12 connecting the two first inner main rib pieces 11. The two first inner main rib pieces 11 and the second inner main rib piece 12 are integrally stamped and formed.

[0055] In an embodiment of the present invention, the inner ribs 2 are also integrally stamped and have a U-shaped cross-section. This provides high strength and resists deformation, ensuring the stability of the multi-fold anti-flip ribs. The inner ribs 2 may include two opposing first inner rib pieces 21 and a second inner rib piece 22 connecting the two first inner rib pieces 21. The two first inner rib pieces 21 and the second inner rib piece 22 are integrally stamped and formed.
