Description

Technical Field

[0001] This utility model relates to the field of umbrella technology, and in particular to a groove structure and umbrella rib. Background Technology

[0002] In existing technologies, common umbrella ribs often employ a three-fold or two-fold design, typically utilizing multiple hinge points to achieve the expansion and folding of the ribs. However, in traditional rib structures, all components are positioned within the same plane, for example... Figure 2 As shown, traditional grooved bone structures have hinge holes on the side of the long grooved bone to hinge the short grooved bone and store the short grooved bone on the side of the long grooved bone. This results in the grooved bone structure taking up a lot of space when stored, making it difficult to achieve a more compact folding effect.

[0003] Based on this, such as Figure 3 As shown, some existing technologies attempt to directly set hinge holes on the long ribs to accommodate the hinged short ribs on top of the long ribs. While this type of structure can improve compactness by stacking some ribs in layers, it also has certain drawbacks. Because a molded part needs to be installed in the middle of the long rib, and the hinge hole is set on the molded part, the long ribs in the existing technology are often independent solid fiberglass rods. However, due to the limitations of current production processes, it is impossible to mold a part with hinge holes in a single operation from a solid fiberglass rod. It is often necessary to first machine-mold the part and then manually drill holes in it to form the hinge points. This results in low overall production efficiency and high costs. Furthermore, manual processing easily leads to inconsistent hole position accuracy, making it difficult to effectively guarantee structural stability and consistency.

[0004] Therefore, how to solve the problem of difficult machining of hinge holes on long groove ribs, while improving the compactness and structural stability of umbrella rib folding, is a problem to be solved by those skilled in the art. Utility Model Content

[0030] Please see below. Figures 1-7 The groove structure provided in this embodiment of the utility model specifically includes:

[0031] The long groove bone 10 includes two bone bodies 11 arranged side by side, with a gap between the two bone bodies 11. A first injection molded part 12 is provided in the middle section. The first injection molded part 12 is wrapped around the two bone bodies 11 and is provided with a first hinge hole 13. The first hinge hole 13 is located in the corresponding position of the gap, and the orientation of the first hinge hole 13 is the same as the orientation of the gap. The first injection molded part 12 and the first hinge hole 13 are integrally injection molded.

[0032] The short groove bone 20 has a fourth hinge hole 21 at one end. The short groove bone 20 is connected to the long groove bone 10 through the fourth hinge hole 21 and the first hinge hole 13. After being stored, the short groove bone 20 is stacked on top of the long groove bone 10 and is located in the direction of the gap.

[0033] In this embodiment, by setting two parallel bone bodies 11 with a gap in the middle in the long groove bone 10, and using an integrally injection molded first injection molded part 12 to wrap the bone body 11 and form a hinge hole at the corresponding position of the gap, the complex process of manually drilling or grooving on the long groove bone 10 is avoided in the later stage, the processing difficulty is reduced, the work efficiency is improved, and the structural stability and consistency are guaranteed.

[0034] In one embodiment, the groove bone structure of this utility model further includes a main material 30 and a tail bone 40. One end of the main material 30 is provided with a sixth hinge hole 31, and the other end is provided with a seventh hinge hole 32 and an eighth hinge hole 33. One end of the tail bone 40 is provided with a ninth hinge hole 41 and a tenth hinge hole 42. One end of the long groove bone 10 is provided with a second hinge hole 14 and a third hinge hole 15, and one end of the short groove bone 20 is also provided with a fifth hinge hole 22.

[0035] The main material 30 is connected to the long groove bone 10 through the seventh hinge hole 32 and the third hinge hole 15. The eighth hinge hole 33 and the fifth hinge hole 22 are connected by the first traction member 50. The two ends of the first traction member 50 are respectively hinged to the eighth hinge hole 33 and the fifth hinge hole 22, and are used to drive the short groove bone 20 to rotate around the fourth hinge hole 21. After the main material 30 is stored, it is located on the side of the long groove bone 10 and is located in the direction perpendicular to the direction of the gap.

[0036] The coccyx 40 is connected to the main body 30 through the tenth hinge hole 42 and the sixth hinge hole 31. The ninth hinge hole 41 and the second hinge hole 14 are connected by the second traction member 60. The two ends of the second traction member 60 are respectively hinged to the ninth hinge hole 41 and the second hinge hole 14, and are used to drive the coccyx 40 to rotate around the tenth hinge hole 42.

[0037] In this embodiment, the long groove rib 10, short groove rib 20, main material 30 and tail rib 40 are reasonably connected through each hinge hole and traction component. When stored, the short groove rib 20 is stacked on top of the long groove rib 10 and located in the direction of the gap. The main material 30 is located on the side of the long groove rib 10 and in the vertical direction of the direction of the gap, forming a staggered layout, which effectively reduces the overall space occupied and effectively improves the compactness of umbrella rib folding.

[0038] In specific application scenarios, the tailbone 40 can be stored on the side of the main material 30 under the action of the second traction component 60, or it can be stacked and stored on top of the main material 30, further optimizing the space occupied after folding.

[0039] In one embodiment, a second injection molded part 16 is provided at one end of the long groove bone 10. The second injection molded part 16 is wrapped around the outside of the two bone bodies 11, and a second hinge hole 14 and a third hinge hole 15 are provided on the second injection molded part 16.

[0040] In this embodiment, the end of the long groove bone 10 is also molded into a second injection molded part 16 by injection molding, integrating the second hinge hole 14 and the third hinge hole 15 therein, thereby achieving a stable hinged connection between the long groove bone 10, the main material 30, and the short groove bone 20. Similarly, injection molded parts can also be provided at the ends of the short groove bone 20, the main material 30, and the tail bone 40 to integrate the hinge holes.

[0041] In one embodiment, a limiting structure 34 is provided in the middle section of the main material 30. The limiting structure 34 protrudes on the outside of the main material 30 and faces the long groove bone 10, and is used to limit the second traction member 60.

[0042] In this embodiment, the limiting structure 34 can prevent the second traction member 60 from shifting during the unfolding or folding of the umbrella ribs, ensuring its stable sliding within a predetermined range. This guarantees the synchronized movement of the tailbone 40, main body 30, and long groove rib 10, improving the reliability and smoothness of the overall movement. Furthermore, the limiting structure 34 also provides support by abutting the second traction member 60 to enhance its stability under stress, preventing structural deformation or wear caused by uneven tension.

[0043] In specific application scenarios, the limiting structure 34 has a through hole in the middle. The second traction member 60 passes through the through hole and its two ends are connected to the ninth hinge hole 41 and the second hinge hole 14 respectively. During the traction process, the hole wall of the through hole guides and constrains the second traction member 60, so that its movement trajectory remains linear and stable, reducing swing and friction loss.

[0044] This utility model embodiment also provides an umbrella rib, including the groove rib structure as described in any of the preceding claims.
