AI Technical Summary
In the existing automatic folding umbrella rib structure, the closing spring and steel wire cannot be fully accommodated, affecting the folding degree of the umbrella rib and resulting in poor closing effect.
Design an automatic folding umbrella rib structure with grooves on the ribs and main body. The umbrella closing spring is connected to the connecting rib, and a limiting mechanism is provided in the groove. When closing the umbrella, the connecting rib drives the main body to close synchronously. The grooves on the ribs and the main body accommodate the umbrella closing spring and return line, achieving a better closing effect.
It achieves a better closing effect for the umbrella ribs, resulting in a shorter height when closed, making it suitable for miniaturized designs. The length of the umbrella canopy remains unchanged when unfolded, while the height is reduced when closed, given the same size.

Technical Field
[0001] This utility model relates to an automatic folding umbrella frame structure, belonging to the field of umbrella technology. Background Technology
[0002] Umbrellas are a very common tool for sunshade or protection from rain and snow. For ease of carrying, umbrellas are often designed with foldable ribs. Existing foldable umbrella ribs, in order to achieve a larger area when unfolded and a shorter height when folded, are often made with five or more folds. For ease of operation, automatic umbrellas with a sliding automatic opening and closing structure are now widely used. When closing the umbrella, the locking spring is unlocked, and the umbrella can be folded up after the tension of the locking spring is released. To enable automatic folding of the umbrella canopy, a new type of folding umbrella rib structure, as disclosed in publication number CN2882343, has emerged. It has a closing spring installed on the ribs. When the umbrella is opened, the closing spring is stretched. When closing the umbrella, the closing spring contracts and pulls the umbrella ribs to close the umbrella canopy automatically. However, since the closing spring and steel wire are installed together between the umbrella ribs, the space between the umbrella ribs in this rib structure is limited and cannot fully accommodate the closing spring and steel wire, thus affecting the degree of folding. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an automatic folding umbrella rib structure that has a better closing effect after the umbrella is closed, which can overcome the shortcomings of the prior art.
[0004] The technical solution of this utility model is: an automatic folding umbrella rib structure, comprising at least one umbrella rib and umbrella support rib, return line, main material, round rib and closing spring, including a connecting rib, the umbrella support rib being transferred to the middle of the umbrella rib, the inner end of the umbrella rib being connected to the lower nest and the outer end being connected to the main material, the inner end of the umbrella support rib being connected to the upper nest and the outer end being connected to one end of the connecting rib, the other end of the connecting rib being connected to the main material, the return line being connected to the main material and the connecting rib respectively, the closing spring being connected to the umbrella rib and the connecting rib respectively, the umbrella rib having a groove on the side facing the closing spring, and the main material having a groove on the side facing the closing spring.
[0005] Furthermore, the outer end of the umbrella rib is connected to the inner end of the main material, and the connection point between the connecting rib and the main material is located on the outer side of the inner end of the main material.
[0006] Furthermore, the groove is provided with a limiting mechanism that cooperates with the return line.
[0007] By implementing this utility model, when closing the umbrella, the closing spring pulls the connecting rib to close, and the connecting rib drives the main material to close synchronously. After closing, the groove of the umbrella rib faces the groove of the main material. The groove and groove can better accommodate the closing spring and return line, thus achieving a better closing effect. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the present invention in its unfolded state;
[0009] Figure 2 This is a schematic diagram of the present invention in its folded state.
[0010] The diagram shows: 1. Umbrella rib; 2. Umbrella support rib; 3. Backing thread 1; 4. Main material 1; 5. Backing thread 2; 6. Main material 2; 7. Round rib; 8. Closing spring; 9. Connecting rib; 10. Positioning pin. Detailed Implementation
[0011] Embodiments of this utility model: such as Figures 1 to 2 As shown, an automatic folding umbrella rib structure includes an umbrella rib 1, umbrella support rib 2, loop 1 3, main material 1 4, loop 2 5, main material 2 6, round rib 7, closing spring 8, and connecting rib 9. The umbrella support rib 2 is connected to the middle of the umbrella rib 1. The inner end of the umbrella rib 1 is connected to the lower nest, and the outer end is connected to the main material 1 4. The inner end of the umbrella support rib 2 is connected to the upper nest, and the outer end is connected to the inner end of the connecting rib 9. The outer end of the connecting rib 9 is connected to the main material 1 4. Loop 1 3 is connected to both the main material 1 4 and the connecting rib 9. The closing spring 8 is connected to both the umbrella rib 1 and the connecting rib 9. The rib 1 has a groove facing the umbrella closing spring 8, and the main material 4 has a groove facing the umbrella closing spring 8. When closing the umbrella, the umbrella closing spring 8 pulls the connecting rib 9 to close, and the connecting rib 9 drives the main material 4 to close synchronously. Under the action of the return line 3 and the return line 2 5, the main material 2 6 and the round rib 7 also close synchronously. After closing, the groove of the umbrella rib 1 faces the groove of the main material 4. The groove and the groove 1 can better accommodate the umbrella closing spring 8, the return line 3 and the connecting rib 9, so that the umbrella rib 1 and the main material 4 can be better gathered together, thus having a better closing effect.
[0012] As a preferred embodiment, the outer end of the umbrella rib 1 is connected to the inner end of the main material 4, and the connection point between the connecting rib 9 and the main material 4 is located on the outer side of the inner end of the main material 4. In the structure disclosed in CN2882343, the joint between the main material and the return line overlaps with the main material when unfolded. In this application, the umbrella rib 1 and the main material 4 are connected at the ends, and there is no overlapping part when unfolded. This makes the total length the same when unfolded, but the height is shorter when folded. This achieves a shorter height when folded while being able to open the same size umbrella surface, which is beneficial for miniaturizing the umbrella.
[0013] As a preferred embodiment, a positioning pin 10 is provided in the groove to block the return line 3. The positioning pin 10 is the limiting mechanism mentioned above. By blocking the return line 3, the return line 3 is limited in the groove. In the closed state, the return line 3 is brought close to the main material 4. At the same time, the main material 6 can be better pulled and restricted. While having a better closing effect, it is also conducive to keeping the umbrella rib structure in the closed state.
