Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 and 2, the large side frame of the splicing type fan comprises a fan fixing frame 1 and a handheld fixing frame 2.

The bamboo wood between the bamboo joints is selected for the sector fixing bone 1, the length of the bamboo wood is shorter than that of the normal fan large-side bone, and at the moment, the handheld fixing bone 2 is added in a splicing mode, namely, the total length of the sector fixing bone 1 is consistent with that of the normal large-side bone due to the splicing of the sector fixing bone 1 and the handheld fixing bone 2.

The top of the bamboo is short for the handheld fixing bone 2, so that the whole bamboo can be completely utilized.

As shown in fig. 1 to 5, in order to ensure the efficiency and accuracy of splicing, the inner surface of the fan fixation bone 1 has a first plane 10, and the inner surface of the hand fixation bone 2 has a second plane 20. When spliced, the first plane 10 and the second plane 20 face the same direction. The splicing mortise 11 is arranged in the middle position of the rear end of the first plane 10; the rear end of the splicing mortise 11 is communicated with the outside so as to be beneficial to clamping the splicing tenon 21 in place; the splicing tenon 21 is arranged at the front end of the handheld fixing bone 2. The thickness of the splicing tenon 21 is smaller than that of the handheld fixing bone 2.

The first plane 10 also has the function of adhesion to the sector.

The splicing tenon 21 is clamped in the splicing mortise 11, one end of the handheld fixing bone 2 provided with the splicing tenon 21 abuts against the rear end of the sector fixing bone 1, and the inner surface of the splicing tenon 21 is flush with the first plane 10. The splicing tenon 21 and the sector fixing bone 1 are connected into an integral structure.

Utilize foretell concatenation mode for the material of bamboo can be totally utilized, not only can prevent the waste of bamboo material, and the while is through polishing the back to the limit bone after the concatenation can satisfy the operation requirement equally, mainly is the requirement of total length.

In order to ensure the structural strength of the splicing part, glue layers are respectively arranged on the groove wall and the groove bottom of the splicing mortise 11 and are connected with the splicing tenon 21, and the glue layers are solidified to realize fixed connection.

Secondly, as shown in fig. 3, a V-shaped groove 12 is formed at the bottom of the mortise 11 along the length direction of the mortise 11, and the V-shaped groove 12 can increase the glue storage amount to further improve the structural strength of the joint. And the rear end face of the sector fixing rib 1 is an arc-shaped concave end face, the front end face of the handheld fixing rib 2 is an arc-shaped convex end face, and the arc-shaped concave end face is matched with the arc-shaped convex end face. Utilize the unsmooth cooperation mode of arc, it can further improve the structural strength of junction because enlarged the contact surface, of course, sets up one deck terminal surface glue film between the sunken terminal surface of arc and the protruding terminal surface of arc.

As shown in fig. 3 and 5, in order to improve the aesthetic appearance, the outer surface of the fan fixation bone 1 has a first arc-shaped convex surface 13, and the outer surface of the hand fixation bone 2 has a second arc-shaped convex surface 22. The design of the first arc-shaped convex surface 13 and the second arc-shaped convex surface 22 also enables the fan edge ribs to be more in ergonomic design.

Preferably, the splicing mortise 11 of this embodiment is a rectangular groove, and the transverse section of the splicing tenon 21 is rectangular.

The method comprises the following steps:

firstly, a sector fixing bone 1 and a hand-held fixing bone 2 are respectively manufactured.

And then arranging a glue layer in the splicing mortise 11, wherein the glue layer needs to be uniformly coated.

The splicing tenon 21 is clamped into the splicing mortise 11, and the end of the handheld fixing rib 2 provided with the splicing tenon 21 is abutted against the rear end of the sector fixing rib 1, and after the glue layer is cured, a fan large-edge rib is formed.

And finally, polishing.
