Folding support device for umbrella main ribs and connecting rods

Abstract

The invention discloses a folding support device for an umbrella main frame and a connecting rod, and relates to the field of umbrellas. The invention solves the problems of weak support of the main frame of the current umbrella and large resistance when the main frames are used in series. The fixing screw holes on both sides of the fixed sleeve of the umbrella main bone and the folding support device of the connecting rod are respectively movably connected with the folding supporting rod one and the folding supporting rod two of equal length by screws, and the connecting rod bolt hole one of the connecting rod one and the connecting rod bolt hole two of the connecting rod two are respectively connected with the sliding bolt holes on both sides of the sliding casing sleeved on the main bone through bolts. The utility model has the advantages of simple structure, easy installation, convenient use and labor saving, enlarged development area and firmer structure.

Description

technical field [0001] The invention relates to the field of umbrellas, in particular to a folding support device for umbrella main ribs and connecting rods. Background technique [0002] Umbrellas have been widely used in various field work and leisure activities due to their small size, light weight, easy portability and simple operation. However, the basic functions of umbrellas such as windproof, rainproof and sunscreen are often contradictory in actual use, especially the general umbrella frame structure design basically has the problem of unreliable fixation, which means that the existing After the umbrella frame is unfolded, it is fixed together by the umbrella cloth instead of being completely fixed by the frame itself at the upper end of the umbrella. That is, if there is no umbrella cloth to fix the existing general umbrella after deployment, the entire umbrella frame will be in an uncertain shape. , which to a certain extent makes the entire umbrella frame weak i...

However, the basic functions of umbrellas such as windproof, rainproof and sunscreen are often contradictory in actual use, especially the general umbrella frame structure design basically has the problem of unreliable fixation, which means that the existing After the umbrella frame is unfolded, it is fixed together by the umbrella cloth instead of being completely fixed by the frame itself at the upper end of the umbrella. That is, if there is no umbrella cloth to fix the existing general umbrella after deployment, the entire umbrella frame will be in an uncertain shape. , which to a certain extent makes the entire umbrella frame have weak wind resistance or other external force resistance problems, and even the phenomenon that the umbrella frame and umbrella cloth are turned over by strong wind under strong wind conditions

[0003] Aiming at the disadvantage that the existing umbrella main ribs are supported by umbrella cloth so that the whole umbrella is not firm when in use, people have designed a method of connecting each adjacent main rib on the umbrella with connecting rods in series to reinforce it. The supporting structure of the umbrella, although the main ribs of the umbrella are indeed reinforced after being connected in series by the connecting rods, but when the umbrella is opened or folded, one end of the connecting rods needs to move a long distance on the main ribs. Greater resistance, the sliding ends of multiple connecting rods move on the corresponding main bones to form greater resistance, so it is difficult to rely on manpower to open or Folding is very inconvenient for people to use normally; at the same time, the sliding end of the connecting rod slides back and forth on the main bone, which will also cause certain damage to the umbrella cloth, which will affect the service life of the umbrella cloth; in addition, if the number of main bones of the umbrella is small, the connecting rod will The length of the connecting rod should be lengthened accordingly, and the fixed position of the longer connecting rod on the main bone needs to be far away from the outer end of the main bone. not firm
