A hand-operated umbrella comprises a column, a tilted rod, a transverse rod, a connecting rod, a supporting rod, an upper nest, a lower nest, a plurality of long rods, a plurality of short rods, and a slider slidably disposed on the column. The transverse rod, the tilted rod, the connecting rod and the supporting rod form a quadrilateral linkage mechanism. The umbrella of the present invention is simple and reasonable in structure, labor-saving and easy to unfold and fold and low in cost. Since each of four sides of the column has the groove for mounting the umbrella frame, so that a shading area of the umbrella is effectively increased, and a shading effect is improved, and the assembled umbrella is stable and reliable.

A sun umbrella locking device includes: a sliding base, a locking clamping base and a fastening assembly, wherein a sliding chamber is formed in the locking clamping base, and two locking pieces are arranged on side surfaces of the locking clamping base; an expansion joint is formed between the two locking pieces, and the expansion joint extends into the sliding chamber of the locking clamping base; the two locking pieces are respectively provided with a first locking hole, the sliding base is provided with an accommodating chamber, and the locking clamping base is arranged in the accommodating chamber; the sliding base is provided with a second locking hole aligned with the first locking hole; after passing through the second locking hole and the first locking hole, the fastening assembly is connected to the sliding base and the locking clamping base.

The present invention relates to the technical field of outdoor umbrellas, particularly to an outdoor umbrella with easy opening and closing mechanism including: an umbrella shaft, in which an actuating assembly, a hydraulic rod, and a cantilever sequentially arranged upward. The actuating assembly is designed to mate with the movement of umbrella shaft, the end of actuating assembly is connected to the top center area of the rib assembly; the cantilever is arranged at the top end of umbrella shaft, the end of cantilever is connected to the bottom center area of the rib; the hydraulic rod is arranged at the upper part of the umbrella shaft, the end of hydraulic rod is connected to the cantilever. The actuating assembly, the hydraulic rod, and the cantilever cooperate to drive the closure of the umbrella canopy. The outdoor umbrella is simple to operate and saves time and labor.
