Assembling and disassembling process of umbrella ribs and upper nest

Abstract

The invention relates to an assembling and disassembling process of umbrella ribs and an upper nest. The process comprises the integral hanging process for completing the hanging of all the umbrella ribs once and the individual umbrella rib detaching and replacing process for independently detaching the umbrella ribs from the upper nest and then carrying out assembling. The detaching and replacingprocess specifically comprises the following steps that a baffle nail on a clamping hole is removed, through plane rotation and upward lifting of an operation round part carried out sequentially, andunder the upward pulling state, plane rotation is carried out so that a target sliding plate and a target umbrella rib are separated; and during single umbrella rib mounting, through plane rotation and upward lifting of the operation round part carried out sequentially, under the upward pulling state, plane rotation is carried out, so that the outer end of the target sliding plate penetrates intoa pivoting hole of a new umbrella rib, finally, plane rotation is carried out till reaching the intimal position after loosing operation, and the baffle nail is used for realizing re-locking. The integral hanging process comprises the followings steps: under the assistances of a tool, the plane of the operation round part flatwise rotates to a specified angle under the downward pressing state, and then the outer ends of sliding plates penetrate through pivoting holes at the inner ends of the umbrella ribs. All the umbrella ribs can be assembled in place once, independent assembling and disassembling also can be carried out, the structure is stable, and the user operation and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of umbrellas, in particular to a process for disassembling and assembling umbrella ribs and upper nests. Background technique [0002] The rib nest structure in the prior art includes: a main rib, an upper rib nest, a retaining tube, a lower rib nest, eight upper ribs, eight lower ribs and two iron wires, wherein the upper rib nest is a A short cylinder with a through hole in the center, a pin hole in the middle of the outer edge, eight pivot grooves at equal angles on the outer edge, a storage groove in the middle, and a long cylinder with a through hole in the center. , the upper end is a large honeycomb part, and its outer edge is equipped with eight pivotal grooves at equal angles, and there is a receiving groove in the middle. The end of the upper rib is flat, with a pivot hole on it, and the end of the lower rib The part is flat, and a pivot hole is opened on it. [0003] When assembling, first fix t...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned structure has the following disadvantages: the upper rib and the lower rib are hinged in the upper rib nest and the lower rib nest, and they must be connected in series with iron wires and then inserted into the hinges of the upper rib nest and the lower rib nest respectively. In the knot groove, the iron wire connecting the upper and lower umbrella ribs in series will produce a sharp winding part after winding. If the user does not pay attention, it will scratch the fingers, and the tightness of the iron wire depends on manual control, or loose or Tightness is not good for the up and down flipping and use of the umbrella ribs. In addition, because all the umbrella ribs are connected in series on the wire, it is impossible to disassemble a single umbrella rib and all need to be opened, which is inconvenient for the user and difficult to operate.
