[0024] The following further details are made in combination with the best embodiments shown in the attached drawings.

[0025] The wind-resistant umbrella ribs of the present utility model are applicable to multi-fold umbrellas with two or more folds. For the convenience of description, here it is defined that the direction close to the umbrella nest body is the inner side, and the direction away from the umbrella nest body is the outer side.

[0026] The following takes the most common three-fold umbrella as an example for illustration. As Figure 1 shown, the wind-resistant umbrella ribs of the present utility model include: a first umbrella rib 1, a second umbrella rib 2, and a third umbrella rib 3 connected in sequence from the inside to the outside, a short rib 4, a short pull wire 5, a movable member 6, an elastic member 7, and a long pull wire 8. Among them, the outer end of the short rib 4 is hinged to the middle of the first umbrella rib 1, the inner and outer ends of the short pull wire 5 are respectively connected to the outer side of the short rib 4 and the inner side of the second umbrella rib 2, and the inner and outer ends of the long pull wire 8 are respectively connected to the outer side of the first umbrella rib 1 and the inner end of the third umbrella rib 3. The inner sides of the short rib 4 and the first umbrella rib 1 are respectively connected to the upper and lower nest bodies of the umbrella. By moving the upper and lower movable nest bodies in the middle, the included angle between the first umbrella rib 1 and the short rib 4 can be changed. By pulling the short pull wire 5 and the long pull wire 8, the entire umbrella skeleton can be driven to expand or fold to realize opening and closing of the umbrella. As Figure 1 and Figure 4 shown, the movable member 6 and the elastic member 7 are installed on the outer side of the first umbrella rib 1.

[0027] In this embodiment, as Figure 3 and Figure 4 shown, the first umbrella rib 1 adopts a grooved rib. A first long hole 63 extending along the length direction of the first umbrella rib 1 is opened in the middle of the movable member 6. The movable member 6 is installed in the inner cavity of the first umbrella rib 1 by passing a rivet through the first long hole 63. In this way, the movable member 6 can move inwards or outwards within the length range of the first long hole 63. And, the inner and outer ends of the side wall at the top of the movable member 6 abut against the inner wall at the top of the first umbrella rib 1, which can prevent the movable member 6 from rotating around the rivet. The outermost end of the movable member 6 extends outwards to protrude a first locking block 61. The first locking block 61 is generally wedge-shaped, with a flat first locking surface 62 at the top and a slidable arc surface or inclined surface at the bottom. A spring hole 64 is opened on the inner side of the movable member 6. The elastic member 7 adopts a spring. The spring is installed in the spring hole 64. The outer end of the spring abuts against the bottom of the spring hole 64, and the inner end abuts against a chicken-eye rivet 9 installed on the first umbrella rib 1. Thus, the spring keeps pushing the movable member 6 outwards.

[0028] As Figure 1 , Figure 2 and Figure 4As shown, an inner joint 21 is provided at the inner end of the second rib 2. The innermost end of the inner joint 21 extends inwards and protrudes with a second locking block 22. The second locking block 22 is generally wedge-shaped, with a flat second locking surface 23 at its bottom and a slidable arc surface or inclined surface at its top. A second long hole 24 extending along the length direction of the second rib 2 is formed in the middle of the inner joint 21. The outer end of the first rib 1 is hinged to the inner joint 21 by passing a rivet through the second long hole 24. Thus, the inner joint 21 can rotate relative to the first rib 1 and move inwards or outwards within the length range of the second long hole 24. A through hole 25 is also formed in the inner joint 21 at a position between the second locking block 22 and the second long hole 24. The outer end of the short pull wire 5 is connected to the through hole 25.

[0029] When the umbrella is opened, the movable nest of the umbrella (not shown in the figure) will drive the inner end of the short rib 4 to move upwards. The short pull wire 5 is pulled inwards, causing the inner joint 21 to drive the second rib 2 to rotate outwards and unfold. Figure 5 As shown, the inner joint 21 rotates until the second locking block 22 at its inner end just touches the first locking block 61 of the movable member 6. At this time, the arc surface or inclined surface at the top of the second locking block 22 abuts against the arc surface or inclined surface at the bottom of the first locking block 61. When the inner end of the short rib 4 continues to move upwards, as Figure 6 shown, the second locking block 22 pushes the movable member 6 to move inwards along the first long hole 63 until the second locking block 22 moves upwards past the first locking block 61. As Figure 7 shown, the movable member 6 moves outwards under the action of the elastic member 7, causing the second locking surface 23 and the first locking surface 62 to abut against each other up and down. At this time, the umbrella is fully opened, and the hinge joint between the first rib 1 and the second rib 2 is locked, and the second rib 2 cannot be turned upwards, so that the ribs of the umbrella will not turn outwards in windy weather and can still be used normally.

[0030] When the umbrella is closed, the movable nest of the umbrella (not shown in the figure) will drive the inner end of the short rib 4 to move downwards. As Figure 8 shown, the short pull wire 5 pushes the inner joint 21 outwards. The inner joint 21 moves outwards along the second long hole 24, and the second locking block 22 of the inner joint 21 disengages from the first locking block 61. Thus, the lock between the first rib 1 and the second rib 2 is released. When the inner end of the short rib 4 continues to move downwards, as Figure 9 shown, the second locking block 22 is completely separated from the first locking block 61. The short pull wire 5 can push the inner joint 21 outwards to cause the second rib 2 to flip and fold, thereby further completing the umbrella closing action.

[0031] Of course, the wind-resistant ribs of the present utility model can also be applied to ribs of other folding numbers, such as ribs of two-fold umbrellas, four-fold umbrellas, etc. Only the corresponding ribs and the corresponding pull wires need to be increased or decreased.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
