Description
Technical Field
The utility model belongs to the technical field of folding fans, and particularly relates to a small rib welding type metal folding fan.
Background
Folding fans generally include large ribs and middle ribs, and fan nails and fan blades.
At present, most of the existing middle small bones are integrally formed, the small bones and the fan surface contact part are often designed to be thinner, and the small bones of the metal folding fan enable the fan surface contact part to be thinned and cut, so that the processing cost is increased, and the processing cost is increased, for example: titanium alloys are particularly evident.
The prior art discloses, for example, chinese patent discloses a folding fan with a Chinese character, patent number: CN202121726482.0, which divides the middle ossicle into two long and short structures, and fixes and adheres the two structures by means of sticky glutinous rice glue, this scheme reduces the cost of cutting a whole ossicle, but is not suitable for metal folding fans, and affects the appearance of the ossicle.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides a ossicle welding type metal folding fan, which comprises: two big limit bones, middle rib, sector and fan nail, its characterized in that: the middle ossicles are positioned between the two big side bones;
the middle ossicles are divided into an ossicle A part and an ossicle B part, the upper end of the ossicle B part is provided with a groove, the thickness of the groove is equal to that of the ossicle A part, the width of the bottom of the ossicle A part is equal to that of the top of the ossicle B part, and the bottom of the ossicle A part is spliced in the groove;
the fan nails are used for stringing the lower ends of the two big side bones and the middle small bone together;
the folding fan further comprises a fan surface, two fan-shaped sides of the fan surface are respectively fixed on the inner surfaces of the two big side bones, and the small bone A part of the middle small bone is inserted into the fan surface gap.
Preferably, the middle ossicles are equal to the lengths of the two large bones, and can be slightly shorter than the lengths of the two large bones.
Preferably, the groove is cuboid, the top of the groove is flush with the top surface of the ossicle B part, and the width of the groove is equal to that of the lower end of the ossicle A part.
Preferably, the ossicle A part and the ossicle B part are fixed by welding.
Compared with the prior art, the utility model has the advantages that:
the structures of the small bones are connected in a welding mode, so that the metal folding fan can be used for the metal folding fan, the processing difficulty of the metal folding fan is reduced, the processing cost is reduced, and the maintenance is convenient; the structural design of the small ribs shortens the connection length between the structures and improves the attractiveness of the small ribs of the folding fan.
