[0016] Figure 3 Fig. 5 is a structural schematic view of the telescopic multi-fold reverse umbrella bone of the present application in a fully open umbrella state. DETAILED DESCRIPTION

[0017] The following will be further described in combination with the best embodiment shown in the drawings.

[0018] The telescopic multi-fold reverse umbrella bone of the present application is suitable for a two-fold or more multi-fold umbrella, and in order to facilitate description, the direction close to the umbrella nest is defined as the inside, and the direction away from the umbrella nest is defined as the outside.

[0019] The embodiment shown in the drawings is a three-fold umbrella bone, such as Figure 1 , Figure 2 and Figure 3As shown in the utility model, the telescopic multi-fold reverse umbrella rib comprises: a main rib 1, a secondary rib 2 and a tail rib 3 connected in sequence from inside to outside, a support rib 4 hingedly connected to the middle of the main rib 1 at one end, a first pull line 5 connecting the support rib 4 and the secondary rib 2, a push-pull rod 6 connecting the main rib 1 and the support rib 4, and a second pull line 7 connecting the main rib 1 and the tail rib 3.

[0020] The main rib 1 comprises: an inner main rib 11 and an outer main rib 12 separated from each other and a telescopic rib 13 inserted between the inner main rib 11 and the outer main rib 12, and the length directions of the inner main rib 11, the outer main rib 12 and the telescopic rib 13 are in the same direction. In this embodiment, the telescopic rib 13 is inserted and fixed in the inner cavity of the inner side of the outer main rib 12, the inner main rib 11 is in a hollow tubular shape, and the telescopic rib 13 is slidably inserted in the inner cavity of the inner main rib 11. Thus, under the guidance of the telescopic rib 13, the inner main rib 11 and the outer main rib 12 can be relatively close or relatively far away along the length direction of the main rib 2, thereby achieving the effect of shortening and lengthening of the main rib 1.

[0021] The inner side of the secondary rib 2 is hingedly connected to the outer end of the outer main rib 12, the inner side of the tail rib 3 is hingedly connected to the outer end of the secondary rib 2, the two ends of the first pull line 5 are respectively connected to the outer side of the support rib 4 and the inner end of the secondary rib 2, the two ends of the second pull line 7 are respectively connected to the outer side of the outer main rib 12 and the inner end of the tail rib 3, and the two ends of the push-pull rod 6 are respectively rotatably connected to the outer side and the inner side of the support rib 4 and the inner main rib 11, and the outer end of the support rib 4 is hingedly connected to the outer main rib 12.

[0022] In particular, the umbrella rib of the utility model adopts a reverse umbrella rib structure, the inner end of the support rib 4 is connected to the upper nest of the umbrella, and the inner end of the inner main rib 11 is connected to the lower nest of the umbrella (the upper nest and the lower nest are not shown in the figure). When the lower nest of the umbrella slides up and down along the middle rod to open and close the umbrella, the included angle between the main rib 1 and the support rib 4 will change, the support rib 4 will rotate around the connection point of the push-pull rod 6, and thus the outer end of the support rib 4 will pull the outer main rib 12 inward to shorten the main rib 1 or push the outer main rib 12 outward to lengthen the main rib 1.

[0023] When the umbrella is opened, the nest under the umbrella will move up, the angle between the main rib 1 and the supporting rib 4 will become smaller, as shown in Figure 2 and Figure 3 The push-pull rod 6 pushes the outer side of the supporting rib 4 to move outward, thus driving the outer main rib 12 to move outward relative to the inner main rib 11, thereby the length of the main rib 1 is elongated, the diameter of the umbrella rib when the umbrella is opened can be increased, thus the shading area of the umbrella cloth is increased.

[0024] When the umbrella is closed, the nest under the umbrella will move down, the angle between the main rib 1 and the supporting rib 4 will become larger, as shown in Figure 1 and Figure 2 The push-pull rod 6 pulls the outer side of the supporting rib 4 to move inward, thus driving the outer main rib 12 to move inward relative to the inner main rib 11, thereby the length of the main rib 1 is shortened, the length of the umbrella rib when the umbrella is closed is reduced, thus it is convenient to put the umbrella into a small bag for carrying.

[0025] In the embodiment, the outer main rib 12 is a slot rib, and the outer side of the telescopic rib 13 is wrapped in the cavity formed by the curling of the outer main rib 12.

[0026] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
