Description

Technical Field

[0001] The utility model relates to the field of umbrella products, in particular to a windproof umbrella rib structure and a windproof umbrella. Background Art

[0002] Umbrellas are essential items in people's lives and can be used in situations such as rain shielding, sun shading, and wind blocking. Generally, when people use umbrellas, they will encounter a common problem. When encountering strong winds, the strong wind often causes the umbrella surface to turn up, making it unable to block, and easily causing damage to the umbrella, especially for multi-fold umbrellas. For this reason, windproof umbrellas have been proposed on the market to solve this problem. Traditional windproof umbrellas are provided with a double-layer umbrella surface, and the windproof umbrella ribs can also effectively enhance the support for the upper umbrella surface. However, in order to achieve the support of multiple sections of umbrella ribs, a plurality of connecting pieces with different specifications and shapes will be set at the connection positions. On the one hand, this increases the weight of the windproof umbrella itself, and on the other hand, more structures are likely to cause the umbrella ribs to be more easily damaged. In addition, during the processing process, different connecting pieces need to be processed separately and then assembled, and the processing steps are more cumbersome, which is not conducive to production and does not contribute to achieving the effect of green energy conservation.

[0003] In order to solve the above existing problems, the utility model provides a windproof umbrella rib structure and a windproof umbrella that can effectively reduce the weight of the windproof umbrella ribs, are conducive to production and processing, and have a longer service life. Summary of the Utility Model
