Umbrella skeleton mechanism, umbrella stand rod and manufacturing method thereof

Abstract

The invention discloses an umbrella skeleton mechanism, an umbrella stand rod and a manufacturing method thereof. The umbrella skeleton mechanism comprises a first nest, a second nest and a pluralityof skeleton units, and the skeleton units comprise first supporting skeletons; the skeleton units also comprises first connecting sections and second connecting sections, the first nest, the first supporting skeletons and the first connecting sections are integrally formed, the second nest and the second connecting section are also integrally formed, bending parts capable of bending are formed between the first nest and the first supporting skeletons, between the first supporting skeletons and the first connecting sections and between the second nest and the second connecting sections, and thefirst connecting sections and the second connecting sections are fixedly installed together to form the second supporting skeletons or parts of the second supporting skeletons; the umbrella skeletonmechanism can be changed between the folding state and the unfolding state through the bending parts. The umbrella skeleton mechanism has the advantages that the number of the assembling times is decreased, assembling is simplified, the labor cost is reduced, a part production mold structure is simplified, mold occupied space and equipment complexity are reduced, the production cost is reduced, and the strength of parts is improved.

Description

technical field [0001] The invention relates to the technical field of an umbrella stand, in particular to an umbrella skeleton mechanism, an umbrella stand and a manufacturing method thereof. Background technique [0002] The traditional umbrella skeleton mechanism includes a first nest, a second nest and several skeleton units connected to the first nest and the second nest at circumferential intervals. The skeleton unit includes a first branch bone and a second branch bone. One end of a branch is rotatably connected to the first nest through a rotating shaft, one end of the second branch is rotatably connected to the middle of the first branch through a clamp, and the other end of the second branch is connected to the second nest through a rotating shaft. The skeleton mechanism generally has at least four sets of skeleton units according to the needs, and each skeleton unit has three rotating connections that need to be rotated and assembled, which makes the assembly of t...

Problems solved by technology

[0004] Such as CN204048402U, since the whole skeleton mechanism is integrally formed, and the first nest and the second nest also have through holes for matching the umbrella pole, so the integrally formed mold needs to be equipped with a core-pulling mechanism, which needs to be equipped with an isolation first bone and The second branch bone and the isolation part that isolates the first nest and the second nest lead to a complex mold structure and a very large space occupation, that is, although the assembly problem is solved, the production problem is actually brought about, and the feasibility is not high;

[0005] Such as CN2423780Y, the parts of the first nest and the second nest are first processed into a belt-shaped structure, and then the belt-shaped structure is surrounded by a sleeve-shaped structure and then locked to maintain the sleeve-shaped structure. On the one hand, adopting this structure will cause the first The structural strength of the first nest and the second nest is reduced. On the other hand, the integrated mold structure is also very complicated and occupies a large space. That is, although the assembly problem is solved, the production problem and the strength problem are actually brought about. Feasibility is not high
