Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Example 1, such as Figures 1-7 As shown, this application provides an embodiment of a pull-wire straight-rib windproof umbrella rib assembly, including a central pole 10, a sliding kit 11, several main ribs 12, and several supporting short ribs 13. One end of the main rib 12 is hinged to the top of the central pole 10. The sliding kit 11 is fitted onto the central pole 10 and slides along the central pole 10. The supporting short ribs 13 are located below the main ribs 12 and one end is hinged to the middle of the main rib 12. The other end of the supporting short ribs 13 is hinged to the sliding kit 11. The windproof umbrella rib assembly also includes a windproof movable pull wire rib 14, a movable joint sleeve 15, and a fixed rubber-coated joint 16. The windproof movable pull wire rib 14 and the main ribs 12... The supporting short bone 13 forms a stable supporting triangular structure at the edge of the umbrella structure. The upper end of the wind-resistant movable tension rib 14 is hinged to the supporting short bone 13, and the lower end of the wind-resistant movable tension rib 14 is hinged to a movable joint sleeve 15. The movable joint sleeve 15 is fitted onto the main bone 12 and slides on the main bone 12. The fixed rubber-coated joint 16 is fixed to the main bone 12 to restrict the movable joint sleeve 15 from sliding upward along the main bone 12, so as to avoid the edge of the umbrella structure being affected by strong winds. The wind-resistant movable tension rib 14 pulls the supporting short bone 13 and the main bone 12 to form a triangle, thereby fixing them and preventing the main bone 12 from folding upward in the opposite direction.

[0034] In this embodiment, by setting the movable joint sleeve 15 and the fixed rubber-coated joint 16, when the main rib 12 is subjected to an upward force, the main rib 12 drives the movable joint sleeve 15 to slide upward on the main rib 12 until the movable joint sleeve 15 abuts against the fixed rubber-coated joint 16. At this time, the wind-resistant movable tension rib 14 has the effect of stretching the main rib 12 upward, improving the rigidity of the end of the main rib 12 and enhancing its wind resistance. By setting the wind-resistant movable tension rib 14, the main rib 12 and the supporting short rib 13 to form a stable supporting triangular structure at the edge of the umbrella structure, when the umbrella structure is subjected to wind force and causes it to bend in the opposite direction, the wind-resistant movable tension rib 14 provides a reverse tension force for the deformation of the main rib 12, thereby preventing the end of the main rib 12 from bending upward in the opposite direction under strong force and causing the umbrella structure to be damaged by strong wind.

[0035] In the embodiment, the umbrella surface is blown by external wind force from inside to the umbrella surface, the fixed position connecting sleeve 38 fixes the position of the active pull wire bone 14 on the supporting short bone 13, the active joint sleeve 15 slides on the main bone 12 with the wind force of the umbrella surface to the position of the fixed rubberized joint 16 and cannot slide any more, the active pull wire bone 14 generates a fixed pulling force to pull the main bone 12 not to bend outward any more, thereby ensuring that the umbrella surface is not blown over.

[0036] Preferably, the wind-resistant umbrella bone assembly further comprises a fixed position connecting sleeve 38, the wind-resistant active pull wire bone 14 is hinged with the supporting short bone 13 through the fixed position connecting sleeve 38, the fixed position connecting sleeve 38 is fixed on one end of the supporting short bone 13 by the rubberizing process so as to be unable to slide, forming a fixed position force, ensuring that the wind-resistant active pull wire bone 14 does not slide at both ends with wind force.

[0037] In the embodiment, when the umbrella surface is blown by external wind force from inside to the umbrella surface, the fixed position connecting sleeve 38 fixes the position of the active pull wire bone 14 on the supporting short bone 13, the active joint sleeve 15 slides on the main bone 12 with the wind force of the umbrella surface to the position of the fixed rubberized joint 16 and cannot slide any more, the active pull wire bone 14 generates a fixed pulling force to pull the main bone 12 not to bend outward any more, thereby ensuring that the umbrella surface is not blown over.

[0038] The wind-resistant principle of the umbrella surface applying the umbrella bone is as follows: when the umbrella surface is blown by external wind force from the front, according to the wind force, the active joint sleeve 15 slides on the main bone 12 between the fixed rubberized joint 16 end and the umbrella surface bead tail 39 end, the fixed position connecting sleeve 38 does not slide synchronously, allowing the wind force to slide on the end of the main bone 12 with the force of the active joint sleeve 15, the main bone 12 bends from the first rubberized joint 31, when the main bone 12 is bent to 90 degrees by the wind force, the active joint sleeve 15 slides to the umbrella surface bead tail 39 at the end of the main bone 12 and reaches the maximum position. The other end of the active pull wire bone 14, the fixed rubberized joint 16, does not slide with the position fixed, pulls the main bone 12 with the fixed position, does not bend any more, thereby ensuring that the umbrella surface is blown by external wind force along the bending of the umbrella surface and changes the position of the force, and the umbrella surface is not blown over.

[0039] Preferably, the wind-resistant umbrella bone assembly further comprises a fixed position connecting sleeve 38, the wind-resistant active pull wire bone 14 is hinged with the supporting short bone 13 through the fixed position connecting sleeve 38, the fixed position connecting sleeve 38 is fixed on one end of the supporting short bone 13 by the rubberizing process so as to be unable to slide, forming a fixed position force, ensuring that the wind-resistant active pull wire bone 14 does not slide at both ends with wind force.

[0040] In the embodiment, the auxiliary support bone 22 is fixed on the support short bone 13 by a one-piece encapsulation process, and because of the wind resistance buffer gap 27 between the movable joint sleeve 15 and the fixed encapsulation joint 16, when subjected to wind pressure, the main bone 12 can bend upward to a certain extent until the movable joint sleeve 15 and the fixed encapsulation joint 16 abut, and the upward bending of the main bone 12 is limited, which not only retains the ability of the main bone 12 to freely bend in a weak wind environment, but also weakens the assembly difficulty and provides wind resistance ability of stable support in a strong wind environment.

[0041] Preferably, the movable joint sleeve 15 includes a connecting sleeve 28 with an inner diameter greater than the diameter of the main bone 12, and two connecting pieces 29 are protruded outward along the diameter of the connecting sleeve 28, and the end of the wind resistance movable pull wire bone 14 is inserted between the two connecting pieces 29 and is hinged through a rotating shaft.

[0043] In the application, the fixed encapsulation joint 16 itself is a fixed length.

The fixed encapsulation joint 16 is a length adjustable device, and the pushing force of the adjusting spring 35 is used to eliminate the wind resistance buffer gap 27, when the main bone 12 is reversely bent upward by wind pressure, the movable end 34 will be pushed in the opposite direction, thereby increasing the support of the end of the main bone 12 and improving the stability of the support.

[0045] Preferably, the wind resistance movable pull wire bone 14 is a pull rod structure with elasticity, has a central cavity for weight reduction, and a plurality of air slots are arranged on the wall of the pull rod to form a continuous "V" shape shock absorption structure.
