Description

Multi-fold rib of turning up

Technical Field

The utility model relates to the technical field of umbrella ribs, in particular to a multi-fold everting umbrella rib.

Background

With the development of science and technology. Umbrellas have also changed from previous oiled paper umbrellas to a wide variety of umbrellas. With the change of the umbrella surface, the umbrella ribs are also changed, the former umbrella ribs are mostly wooden and bamboo umbrella ribs, later on, iron ribs, steel ribs, aluminum alloy ribs (also called fiber ribs), electric ribs and resin ribs are available, and the former umbrella ribs are mostly contraction ribs (umbrella ribs), so that the umbrella is light and convenient to carry. The steel skeleton is most firm and durable, is not easy to break and has long service life. The iron bone is hard and not easy to break, and has good windproof performance, namely the iron bone is easy to rust after a long time. The umbrella net aluminum ribs, the electric bonding ribs and the resin ribs are relatively light and portable, and the umbrella is more in light series. Its disadvantages are easy to break and poor wind-proof performance.

Although the length of the folded umbrella rib can be reduced by adopting a multi-link pin joint mode, the contraction length of the umbrella rib still cannot meet the requirement of some users, so that the practicability is not strong.

SUMMERY OF THE UTILITY MODEL
