Improved upper nest structure for umbrella

Abstract

The invention relates to an improved upper nest structure for an umbrella. The improved upper nest structure for the umbrella comprises a nest seat and a nest cover. A seat hole and an operating roundpiece concentrically arranged outside the seat hole are arranged at the top center of the nest seat, a sliding groove and accommodating grooves are formed in the top edge of the nest seat, and sliding sheets are arranged between the operating round piece and the sliding groove; the outer ends of the sliding sheets are arranged in the sliding groove in an adaptive mode, driven parts are arranged at the inner ends of the sliding sheets, first driving parts matched with the driven parts are arranged on the upper part of the outer wall of the operating round piece, and second driving parts matched with the side surfaces of the sliding sheets are arranged on the lower part of the outer wall of the operating round piece; and bearing inner pieces are installed at the center of the bottom of theoperating round piece in an embedded mode, the bearing inner pieces and the nest seat are fixedly connected with elastic pieces, and when the elastic pieces are at the initial height, the second driving parts are located below the sliding sheets while the first driving parts are located above the sliding sheets. The nest cover is arranged at the top of the nest seat, limiting ring grooves and hanging grooves are formed in the bottom of the nest cover, upward pulling spaces are reserved between the nest cover and the operating round piece, and the upper end of the operating round piece penetrates through the nest cover. Umbrella ribs of the improved upper nest structure for the umbrella can be fully assembled in place at one time, or target ribs can further be separately disassembled and assembled, the structure is stable, and the operation and use by a user are convenient.

Description

technical field [0001] The invention relates to the technical field of umbrellas, in particular to an improved upper nest structure for umbrellas used for hanging umbrella ribs. 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 ...

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.
