Disassembly and assembly process of umbrella rib and upper nest

Abstract

The invention relates to the disassembly and assembly process of the umbrella ribs and the upper nest, which is divided into the overall hanging process of completing the hanging of all the umbrella ribs at one time and the single bone disassembly and replacement process of separately dismantling and reassembling the umbrella ribs from the upper nest. The dismantling process specifically includes The steps are as follows: take out the retaining nail on the clamping hole, operate the round piece through plane rotation and lifting in turn, and then rotate the plane while keeping the pull up state to separate the target slide from the target rib; when installing a single rib, sequentially pass through Plane rotation and lifting operation The round part is then rotated in a plane while maintaining the pull-up state so that the outer end of the target slider penetrates the pivot hole of the new rib, and finally loosened and then rotated in a plane to the initial position and then locked again with a stopper . The overall hanging process includes rotating the plane of the operating circular piece at a specified angle while maintaining the pressed state with the aid of tooling, and then making the outer ends of each sliding piece pass through the pivot holes at the inner end of the umbrella ribs. The umbrella frame of the present invention can be fully assembled in place at one time, and can also be disassembled separately, has a stable structure, and is convenient for users to operate and use.

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.
