The outer end part of the first umbrella rib (41) extend outwards along the connecting point of the first umbrella rib and the second umbrella rib, the pull rod (46) is located below the second umbrella rib (42), the connection point of the inner end of the pull rod (46) and the first umbrella rib (41) is located outside the connection point of the first umbrella rib (41) and the second umbrella rib (42), and the connection point of the outer end of the pull rod (46) and the third umbrella rib (43) is located outside the connection point of the second umbrella rib (42) and the third umbrella rib (43). After the multi-folding umbrella is unfolded, the size of the unfolded umbrella is large, the length of the folded umbrella is short, and the multi-folding umbrella is convenientto carry.

Description

technical field [0001] The invention relates to an umbrella for daily use, in particular to a structural improvement of an automatic opening and closing multi-folding umbrella. Background technique [0002] Now the automatic opening and closing multi-folding umbrellas on the market can realize the umbrella opening action of stretching the middle stick and opening the umbrella ribs or the umbrella closing action of folding the umbrella ribs by pressing the button on the umbrella handle. It is very popular because it is very convenient to use. . The ribs of the automatic multi-fold umbrella are usually made into 3-5 folds, and the ribs are connected together by rivets and other parts.

Problems solved by technology

[0004] Among the components of the above-mentioned safety device, the diameter of the winding shaft of the existing winding wheel is the same along its length direction. In this way, there needs to be enough space at the reel to ensure its normal operation. In addition, the size of the mainspring is also larger, which also requires a larger space to accommodate, so the existing safety device needs to occupy the inside of the umbrella handle. The larger space also increases the length of the umbrella handle, further increasing the length of the umbrella after the umbrella is folded, making it inconvenient to carry the umbrella in the bag, and if you want to achieve a shorter folding length, you can usually only More ribs are used, but this also increases the labor required for rib parts and assembly, resulting in increased costs
