Description

Technical Field

[0001] This utility model relates to the field of origami fan technology, specifically to an anti-wrinkle origami fan. Background Technology

[0002] A paper fan is a fan made by folding paper. It is both a traditional handicraft and a cultural art, and it plays an important role in people's daily life and cultural activities. The main material for making paper fans is paper, and paper with good toughness and moderate thickness, such as Xuan paper and cardstock, is generally selected.

[0003] However, existing technologies still have the following problems:

[0004] Most traditional origami fans in the current technology lack a clear folding trajectory to guide the fan surface. When opening and closing, the fan surface folds arbitrarily, with inconsistent folding angles and positions. Over time, this causes messy folds on the fan surface, affecting its appearance and usability. Furthermore, most existing origami fans only connect the fan surface and fan ribs through simple gluing or sewing, which is prone to loosening during use. This leads to uneven stress on the fan surface, making it very easy for folds to appear after frequent opening and closing. Although some paper fans have reinforcement designs, the reinforcement points are few and poorly distributed, which cannot effectively restrain the fan surface, making it difficult to solve the folding problem.

[0005] To address the aforementioned problems, the inventors proposed a folding paper fan with an anti-wrinkle surface. Utility Model Content

[0006] To address the issues of unclear folding trajectories and loose structural connections in the fan surface, the purpose of this utility model is to provide a folding fan with an anti-wrinkle surface.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fan-shaped anti-wrinkle folding fan, comprising two side rods, a plurality of inner rods rotatably disposed between the two side rods, a through decorative groove on one side of each inner rod, a plurality of through slots on one side of each inner rod, a fan body fixedly connected between the two side rods, a plurality of creases on the outer surface of the fan body, a reinforcing component between the fan body and the side rods, and an insertion rod fixedly disposed at the outer end of each inner rod, the insertion rod being fixedly inserted into the fan body.

[0008] Preferably, a support shaft is provided through the side rod and the inner rod, and a limiting plate is symmetrically fixed at both ends of the support shaft, and the inner side of the limiting plate is movably fitted with the corresponding side rod.

[0009] Preferably, eight reinforcing components are provided between one of the side rods and the paper fan body, and the eight reinforcing components are distributed at the same spacing. Each reinforcing component includes a screw tube. The paper fan body and the side rod are both provided with grooves, and the screw tube is inserted into the corresponding groove. One end of the screw tube is threadedly connected to a stud. The outer end of the stud is fixedly provided with a knob, and one side of the knob is movably fitted with the corresponding side rod. The outer end of the screw tube is fixedly provided with a chuck, and the chuck is movably fitted with the paper fan body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features creases on the outer surface of the paper fan body, providing a fixed folding trajectory for opening and closing the paper fan. This allows the paper fan to fold neatly along the creases during opening and closing, avoiding wrinkles caused by random folding. The inner rod is fixedly connected to the paper fan body through an insertion rod. When the paper fan is opened and closed, the rotation of the inner rod can evenly drive the paper fan body to unfold or fold, ensuring that the paper fan body is subjected to uniform force and reducing wrinkles caused by uneven force.

[0012] 2. This utility model uses reinforcing components to firmly connect the paper fan body to the side rod, restricting the movement and deformation of the paper fan body, thereby effectively preventing wrinkles from forming on the fan surface during use due to shaking or displacement; multiple reinforcing components are distributed at the same interval, which can reinforce multiple parts of the paper fan body, further improving the anti-wrinkle effect; in addition, the through groove on the inner rod reduces the weight of the inner rod, making the paper fan easier to open and close, reducing the pulling of the paper fan body caused by excessive force when opening and closing, and thus avoiding the formation of wrinkles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides a fan-shaped anti-wrinkle paper fan, including two side rods 1, a plurality of inner rods 2 rotatably arranged between the two side rods 1, a paper fan body 3 fixedly connected between the two side rods 1, a plurality of creases 31 provided on the outer surface of the paper fan body 3, a reinforcing component 5 provided between the paper fan body 3 and the side rods 1, an insertion rod 21 fixedly provided at the outer end of the inner rod 2, and the insertion rod 21 is fixedly inserted into the paper fan body 3, connecting the inner rod 2 and the paper fan body 3, so that the inner rod 2 can drive the paper fan body 3 to move together when rotating, ensuring the continuity of the opening and closing of the paper fan.

[0020] A through-type decorative groove 22 is provided on one side of the inner rod 2, and several through-type slots 23 are provided on the other side of the inner rod 2. The inner rod 2 is connected to the side rod 1 through the support shaft 4, which allows for flexible rotation and makes opening and closing the paper fan easier. The limiting plate 41 ensures the stability of the rotation of the inner rod 2, making the opening and closing process of the paper fan smooth and without jamming. The through-type slots 23 on the inner rod 2 reduce the weight of the inner rod 2, making the overall weight of the paper fan lighter and easier for the user to hold and operate. The presence of the decorative grooves 22 increases the aesthetics of the inner rod 2 and enhances the overall visual effect of the paper fan, making the paper fan not only practical but also aesthetically pleasing.

[0021] A support shaft 4 runs through the side rod 1 and the inner rod 2. The two ends of the support shaft 4 are symmetrically fixed with limiting discs 41. The inner side of the limiting disc 41 is in contact with the corresponding side rod 1. When the paper fan needs to be opened, hold the two side rods 1 and unfold them outward. Since the inner rod 2 is connected to the side rod 1 through the support shaft 4 and the inner rods 2 are also connected to each other through the support shaft 4, the inner rod 2 can rotate around the support shaft 4, thereby driving the paper fan body 3 to unfold. When closing the paper fan, the operation is reversed, and the inner rod 2 rotates around the support shaft 4 to fold the paper fan body 3.

[0022] Eight reinforcing components 5 are provided between one of the side rods 1 and the paper fan body 3, and the eight reinforcing components 5 are distributed at the same interval. The reinforcing components 5 include a screw tube 51. The paper fan body 3 and the side rod 1 are both provided with a groove 52, and the screw tube 51 is inserted into the corresponding groove 52. One end of the screw tube 51 is threadedly connected to a stud 53. A knob 54 is fixedly provided at the outer end of the stud 53, and one side of the knob 54 is movably fitted with the corresponding side rod 1. The outer end of the screw tube 51 is fixedly... A chuck 55 is fixedly provided, and the chuck 55 is movably fitted with the paper fan body 3. During the opening or closing of the paper fan, the reinforcing component 5 plays the role of fixing the paper fan body 3 and the side rod 1. The screw tube 51 is inserted into the column groove 52 of the paper fan body 3 and the side rod 1. By rotating the knob 54, the stud 53 moves threadedly in the screw tube 51, so that the chuck 55 is pressed tightly on the paper fan body 3, further strengthening the connection between the paper fan body 3 and the side rod 1 and preventing the paper fan body 3 from separating from the side rod 1.

[0023] Working principle: When the paper fan needs to be opened, hold the two side rods 1 and unfold them outwards. Since the inner rod 2 is connected to the side rods 1 through the support shaft 4 and the inner rods 2 are also connected to each other through the support shaft 4, the inner rod 2 can rotate around the support shaft 4, thereby driving the paper fan body 3 to unfold. When closing the paper fan, the operation is reversed, and the inner rod 2 rotates around the support shaft 4 to fold the paper fan body 3.

[0024] During the opening or closing of the paper fan, the reinforcing component 5 serves to fix the paper fan body 3 and the side rod 1. The screw tube 51 is inserted into the column groove 52 of the paper fan body 3 and the side rod 1. By rotating the knob 54, the screw 53 moves threadedly in the screw tube 51, so that the chuck 55 is pressed tightly on the paper fan body 3, further strengthening the connection between the paper fan body 3 and the side rod 1 and preventing the paper fan body 3 from separating from the side rod 1.

[0025] The decorative groove 22 and through groove 23 on one side of the inner rod 2 enhance the aesthetics of the inner rod 2. At the same time, the through groove 23 reduces the weight of the inner rod 2, making it easier to rotate the inner rod 2 when opening and closing the paper fan and reducing the resistance during rotation.

[0026] The insertion rod 21 at the outer end of the inner rod 2 is fixedly inserted into the paper fan body 3, connecting the inner rod 2 to the paper fan body 3, so that the inner rod 2 can drive the paper fan body 3 to move together when it rotates, ensuring the continuity of the opening and closing of the paper fan.

[0027] The limiting discs 41 at both ends of the support shaft 4 are in contact with the side rod 1, restricting the axial movement of the support shaft 4 during rotation, ensuring that the inner rod 2 can rotate stably around the support shaft 4 when rotating, avoiding wobbling between the inner rod 2 and the side rod 1, and making the opening and closing of the paper fan more stable.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
