Embodiment 1

[0038] Such as Figure 2-Figure 4 As shown, this embodiment provides a combined fan bone structure including fan bone 1, fan bone nailing block 2, shrinkage groove 21, shrinkage groove matching protrusion 10 and restraint structure, the width of fan bone 1: the front end is wide, and the rear end is narrow .

[0039] The fan bone can be any one of the large side bone and the small side bone.

[0040] A pin hole 20 is provided on the fan bone nail block 2, and the pin hole 20 is a circular hole.

[0041] Shrinking groove 21 is arranged on the fan bone piercing block 2, and the shape of fan bone piercing block 2 is circular and prismatic or the like structure.

[0042] The shrinking groove and the protrusion 10 are arranged at the rear end of the fan rib 1 .

[0043] The notch width of the necking groove 21 is smaller than the groove bottom width of the necking groove 21, and the necking groove matching protrusion 10 matches the necking groove 21 to prevent the necking groove...

Embodiment 2

[0067] Based on the first embodiment, this embodiment provides a Wenwan folding fan, which has the combined fan bone structure described in the first embodiment.

Abstract

The invention belongs to the technical field of fan manufacturing, and particularly relates to a combined fan rib structure and an assembling method. The technical problem that in the prior art, design is not reasonable is solved. The provided combined fan rib structure comprises a fan rib; a fan rib nail penetrating block, wherein a pin hole is formed in the fan rib nail penetrating block; a necking groove, which is formed in the fan rib nail penetrating block; a necking groove matching protruding block arranged at the rear end of the fan rib, wherein the notch width of the necking groove is smaller than that of the bottom of the necking groove, and the necking groove matching protruding block is matched with the necking groove to prevent the necking groove matching protruding block from being separated from the notch of the necking groove; and a restraining structure, which is arranged between the two sides of the necking groove matching protruding block and the groove wall of the necking groove and used for fixing the fan rib nail penetrating block relative to the necking groove in the thickness direction. The combined fan rib structure has the advantage that the problem of drilling cracking is solved.

Description

technical field [0001] The invention belongs to the technical field of fan manufacturing, and in particular relates to a combined fan frame structure and an assembly method. Background technique [0002] Wenwan folding fans are generally assembled from fan bones and fan paper. [0003] Such as figure 1 As shown, the back end of the fan bone (that is, the end of the handle) will be drilled to facilitate the insertion of the pin. After the two ends of the pin are riveted, the pin will string several fan bones together. At this time, the fan can be opened and folded. . [0004] Since the fan bone, especially the middle small bone, has a narrow rear end width, it is easy to cause the fan bone to crack when drilling, and the processing is difficult. Contents of the invention [0005] The object of the present invention is to address the above problems and provide a combined fan bone structure and assembly method that can solve the above technical problems. [0006] To achie...
