Description

Folding umbrella bone straight structure

Technical field:

The utility model relates to the technical field of umbrellas, in particular to a folding umbrella bone straightening structure of a two-fold or more than two-fold multi-fold umbrella.

Background technique:

Umbrellas are used as daily necessities for people to keep out the sun and rain, and are favored by people because of their lightness and practicality. Especially the multi-folding umbrella, because it can be folded and placed, and is easy to carry, there are many current users. The ribs of multi-fold umbrellas are divided into two folds or more. In order to reduce the folded volume of the umbrella and increase the strength, the ribs gradually change from the original U-shaped groove ribs to round solid ribs, especially the outer main body at the end. Bones are almost always cylindrical rods. However, as we all know, the cylindrical rod body lacks directionality and can deflect at will; therefore, when the multi-fold ribs are opened, the circular rib segment will deflect, which will affect the straight opening of the ribs, especially the circular ribs that lack directional auxiliary guidance. The rib section is relatively easy to deflect, and even twisted relative to the pivotal end, which will hinder the opening of the umbrella and affect the use of the umbrella.

Invention content:

The purpose of the utility model is to overcome the defects of the prior art and provide a simple and practical folding umbrella rib straightening structure.

In order to achieve the above object, the utility model includes a first pivot joint and a second pivot joint, wherein one end of the first pivot joint is provided with a pivot joint and one end of the second pivot joint, and the pivot joint and the first pivot joint can be integrated In the molded structure or combined structure, there is a concave folded portion on the second pivot bone to help the pivot bone to open and straighten, and the direction of the concave fold is the same as or opposite to the umbrella opening direction of the second pivot bone.

The concave part is integrally formed with the second pivot bone, and the concave part leans against the end of the pivot connection between the second pivot bone and the first pivot bone. The second pivot bone is a round solid bone, and the pivot of the second pivot bone The connecting end and the second pivot bone can be integrally formed or combined.

The concave folded portion is in the shape of "V", "U" or polygon.

Compared with the prior art, the utility model has the following advantages:

1. There is a concave fold on the second pivot bone, and the direction of the concave fold is the same as or opposite to the opening direction of the second pivot bone. In this way, the orientation of the concave fold is used to open the umbrella of the second pivot bone Guided to prevent deflection, the multi-fold ribs open smoothly and have good straightness.

2. The concave fold and the second pivot bone are integrally formed, with simple processing technology, material saving and low cost.

3. Increase the service life of umbrella ribs.
