Description

technical field [0001] The invention relates to the field of umbrellas, in particular to an umbrella bracket with main bones connected in series. Background technique [0002] Umbrellas have been widely used in various field work and leisure activities due to their small size, light weight, easy portability and simple operation. However, the basic functions of umbrellas such as windproof, rainproof and sunscreen are often contradictory in actual use, especially the general umbrella frame structure design basically has the problem of unreliable fixation, which means that the existing After the umbrella frame is unfolded, it is fixed together by the umbrella cloth instead of being completely fixed by the frame itself at the upper end of the umbrella. That is, if the existing umbrella is deployed without the umbrella cloth to fix it, the entire umbrella frame will be in an uncertain shape. To a certain extent, the entire umbrella frame has the problem of weak wind resistance o...

However, the basic functions of umbrellas such as windproof, rainproof and sunscreen are often contradictory in actual use, especially the general umbrella frame structure design basically has the problem of unreliable fixation, which means that the existing After the umbrella frame is unfolded, it is fixed together by the umbrella cloth instead of being completely fixed by the frame itself at the upper end of the umbrella. That is, if the existing umbrella is deployed without the umbrella cloth to fix it, the entire umbrella frame will be in an uncertain shape. To a certain extent, the entire umbrella frame has the problem of weak wind resistance or other external forces, and even the phenomenon that the umbrella frame and umbrella cloth are turned over by strong wind under strong wind conditions.
