Abstract

The present invention relates to an effortless unfolding structure of sunshade umbrella, which comprises a cantilever, a pulling rope, an elastic component and a fixing block. The pulling rope comprises a first end part and a second end part. The second end part, the elastic component and the fixing block are all arranged inside the cantilever. The first end part threads though the end face of the cantilever and the second end part is fixed to the fixing block. The elastic is arranged between the end face of the cantilever and the fixing block with its two ends resisting against the end face of the cantilever and the fixing block respectively. Preferably, the elastic component is a spring and the spring sleeves outside the pulling rope. The fixing block is an end face snap-fit piece. A bearing component for the pulling rope is also comprised, and the first end part winds part of the bearing component for the pulling rope. A fixing block for the oblique rods and a locking plate are also comprised. The bearing component for the pulling rope is mounted on the fixing block for the oblique rods. The first end part is fixed on the fixing block for the oblique rods, and the fixing block for the oblique rods is fixed to the post of the sunshade umbrella by means of the locking plate. The effortless unfolding structure of sunshade umbrella is ingeniously deigned, concise in structure and can facilitate to open umbrella in a labor saving way. Besides, its overall appearance will not be damaged. It is suitable to be promoted and applied on a large scale.

Description

FIELD OF TECHNOLOGY[0001]The present invention relates to the technical field of umbrellas, particularly to the technical field of sunshade umbrellas, and more particularly to an effortless unfolding structure of sunshade umbrella which facilitates to unfold the umbrella in a labor-saving way.DESCRIPTION OF THE PRIOR ART[0002]Nowadays, sunshade umbrellas can be seen everywhere. Some types of the sunshade umbrellas have effortless unfolding structures, while similar existing products on the market are all provided with external gas springs to achieve the effortless unfolding of the umbrellas.
