Abstract

An automatic multi-section umbrella comprises a retractable middle umbrella bar and an umbrella rib device which can be opened and closed. A lower nest is arranged on the middle umbrella bar in a sliding manner; an upper nest is arranged at the upper end of the middle umbrella bar; an umbrella head is arranged at the lower end thereof; the umbrella rib device is connected with the middle umbrella bar through the upper nest and the lower nest; and a positioning device is arranged between the umbrella head and the lower nest and enables the both to be positioned with each other. When the umbrella is closed, the positioning device between the lower nest and the umbrella head enables the lower nest to be positioned on the umbrella head, so that the elasticity of a main spring inside the middle umbrella bar can be overcome, the middle umbrella bar is in the retraction state, and the umbrella rib device is in the closing state. The fixation manner avoids the formation of holes in the middle umbrella bar, thereby not only increasing the strength of the middle umbrella bar, but also reducing the processing difficulty.

Description

The umbrella that a kind of many foldings are opened automatically

Technical field

The utility model relates to parachute kit, specifically is meant the umbrella that a kind of many foldings are opened automatically.

Background technology

In the prior art, but the structure of the umbrella that many foldings are opened automatically mainly comprises rod and folding umbrella rib device in the telescopic umbrella, is provided with in the rod in the umbrella to drive outer tube, middle pipe, the interior pipe spring of stretching, extension relatively; Be slidingly equipped with down nest in the umbrella on the rod, its upper end is provided with nest, and the lower end is provided with the umbrella head; Be provided with bullet joint in the umbrella head, the relevant position of rod is provided with and cooperates with this bullet joint so that the excellent bullet knothole that is positioned contraction state in the umbrella in the umbrella; Umbrella rib device is by upward nest, following nest are connected with rod in the umbrella.
