However, the movable connection structure between the fan blades in this design is complex, making assembly difficult. Utility Model Content

[0004] To address the aforementioned shortcomings, the technical problem to be solved by this utility model is to provide a folding fan with an unfolding and closing connection structure between metal assembly model sheets, thereby solving the problem that the existing movable connection structure between two sheets is complex and difficult to assemble.

[0005] Therefore, this application provides an unfolding and closing connection structure between metal assembly model sheets for sliding unfolding or closing between two sheets. The sheet has a transversely arranged groove and a bendable clip. The groove passes through the sheet and is arranged on the side of the groove along the sliding direction of the sheet. The width of the root of the clip is adapted to the width of the groove, and the width of the root of the clip is smaller than the width of the head of the clip.

[0012] In the above technical solution, preferably, four bendable central splicing pins are provided on the two horizontal sides of the window, and a central insertion hole is provided on the second sheet corresponding to the central splicing pins; the four central splicing pins of the first sheet are bent vertically and pass through the central insertion hole of the second sheet, and then bent and abutted against the outer surface of the second sheet.

[0013] In the above technical solution, preferably, the four central splicing pins are arranged opposite each other in pairs, with two of the central splicing pins positioned directly opposite the root of the clamping piece. This embodiment optimizes the position of the central splicing pins, simplifying design and manufacturing.

[0042] Most existing metal model kits cannot slide or fold, and therefore lack functionality. Metal folding fans, unlike paper or cloth fans, require movable connecting structures between the fan blades to ensure continuity between them when the fan is unfolded, thus creating a beautiful display.

[0043] Existing foldable metal folding fans have complex structures and are inconvenient to assemble because the fan blades are connected by pins on their sides.

[0044] The proposed solution adopts a sheet assembly structure. Each sheet has a horizontally arranged groove and a bendable clip. In two adjacent sheets, the bendable clip on one sheet passes through the groove on the other sheet and then bends and fits together to form an unfolding and closing connection structure between the sheets. One sheet can slide in the slide rail of another sheet through its clip to unfold or close.

[0045] Compared to the existing technology of side-hinged fan blades, this application adopts a structure of integral sheet assembly, preserving the fun of hands-on and intellectually stimulating assembly. Simultaneously, the assembled folding fan can open and close, giving the metal model toy functionality and improving the user experience. The sliding connection structure consists of a groove and bendable clips, resulting in a simple structure and easy assembly.

[0046] 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 embodiments described below 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.

[0047] To provide a clearer explanation and description of the technical solution and implementation method of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0048] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0049] The present invention provides a metal assembly model sheet unfolding and closing connection structure for sliding unfolding or closing between two sheets.

[0050] like Figure 1 As shown, the sheet 10 has a transversely arranged groove 11 and a bendable clamping piece 12. The groove 11 extends through the thickness direction of the sheet 10, and the clamping piece 12 is arranged beside the groove 11 along the sliding direction of the sheet. The width of the root 121 of the clamping piece 12 is adapted to the width of the groove 11, and the width of the root 121 of the clamping piece 12 is smaller than the width of the head 122 of the clamping piece 12, so as to realize the limiting function after the clamping piece 12 is bent. The clamping piece 12 can be bent into shape during assembly. Figure 2 , Figure 3 The state shown.

[0051] like Figure 4 As shown, in two adjacent sheets, the bendable clip 12 on one sheet passes through the groove 11 on the other sheet and bends and adheres to the surface of the other sheet, forming an unfolding and closing connection structure between the sheets. The clip 12 can slide along the groove 11 and is limited by the groove 11.

[0052] The clip 12 is formed on the sheet 10 and is flush with the surface of the sheet 10 when it leaves the factory. During assembly, the clip 12 can be bent to achieve the corresponding function.

[0053] Figure 1 The shape of the sheet shown is for illustrative purposes only. In specific product applications, it is not limited to a rectangular shape, and the shape of the sheet can be designed according to the specific product.

[0054] By applying the above-mentioned open and close connection structure between metal assembly model sheets, this application also provides an assembly-type metal craft folding fan.

[0055] like Figure 5 As shown, this modular metal folding fan includes multiple fan-shaped blade units 100 hinged at the lower end. Each blade unit 100 has the aforementioned interlocking structure for opening and closing between metal assembly model sheets, configured such that one blade unit can slide within a through groove of another blade unit via a clip on its blade, thus opening or closing. The lower ends of the multiple blade units 100 are hinged together by a pivot 200. Each blade unit 100 has a perforated pattern, forming a beautiful fan surface pattern when the fan is opened.

[0056] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, each fan blade unit 100 is formed by bonding and fixing a first sheet 110 and a second sheet 120 together.

[0057] The upper middle part of the first sheet 110 has a hollowed-out arc-shaped window 111. The arc-shaped window 111 is horizontally positioned, and a bendable first sheet clip 112 is provided on one vertical side. The width of the first root 113 of the first sheet clip 112 is smaller than the overall width of its first head 114. The first sheet clip 112 corresponds to... Figure 1 Clip 12 in the middle.

[0058] A hollowed-out arc-shaped slide rail 121 is provided on the second sheet 120 at the position corresponding to the arc-shaped window 111 of the first sheet 110. The width of the arc-shaped slide rail 121 is adapted to the first root 113 of the first sheet clip 112, and it is centered in the vertical direction relative to the arc-shaped window 111. Therefore, the width of the arc-shaped slide rail 121 is smaller than the width of the arc-shaped window 111.

[0059] The first sheet 110 and the second sheet 120 are connected and fixed by bendable and splicing pins. Specifically, the top of the first sheet 110 is provided with two or more upper splicing pins 115 spaced apart. The second sheet 120 is provided with upper insertion holes 122 corresponding to the upper splicing pins 115. The two lateral sides of the arc-shaped window 111 are respectively provided with four bendable middle splicing pins 116, which are arranged in pairs facing each other, with two of the middle splicing pins 116 directly facing the first root 113 of the first sheet clip 112. The second sheet 120 is provided with middle insertion holes 123 corresponding to the middle splicing pins 116.

[0060] The first fan unit 310 and the second fan unit 320 are two adjacent fan units that form a sliding connection structure through a bendable first sheet clip 112. One of the fan units 310 can slide in the arc-shaped slide rail 121 through the first sheet clip 112, thereby realizing the opening or closing of the two fan units 310 and 320, and thus realizing the opening or closing of the folding fan as a whole.

[0061] The assembly steps for fan blade unit 100 are as follows:

[0062] like Figure 12 , Figure 13 As shown, the two upper splicing pins 115 of the first sheet 110 are bent vertically and inserted into the upper insertion holes 122 of the second sheet 120, and the four middle splicing pins 116 of the first sheet 110 are bent vertically and inserted into the middle insertion holes 123 of the second sheet 120.

[0063] The upper splicing pin 115 and the middle splicing pin 116 are bent vertically and placed against the outer surface of the second sheet 120, thereby connecting and fixing the first sheet 110 and the second sheet 120 to form a fan-shaped unit, as shown below. Figure 6 As shown.

[0064] like Figure 14 As shown, take out two adjacent fan blade units, the first fan blade unit 310 and the second fan blade unit 320, rotate the second fan blade unit 320 to be perpendicular to the first fan blade unit 310, and pass the first sheet clip 112 on the first fan blade unit 310 through the arc-shaped slide rail 121 on the second fan blade unit 320.

[0065] like Figure 15 As shown, the first sheet clamp 112 is bent and attached to the outer side of the second fan-shaped unit 320 to form a movable connection structure of the fan-shaped unit, thus completing the sliding connection between the first fan-shaped unit 310 and the second fan-shaped unit 320. The second fan-shaped unit 320 can slide along the arc-shaped slide rail 121 by being limited by the first sheet clamp 112, and can unfold or close relative to the first fan-shaped unit 310.

[0066] After connecting all the fan blade units in the same way, the metal folding fan is assembled. The fan surface can be opened or closed by sliding along the arc-shaped rail at the base of each clip.

[0067] In this application, the metal folding fan adopts a modular structural design, and the whole is assembled from sheets. For example... Figure 16 As shown, multiple first sheets and / or multiple second sheets are respectively formed on one or more sheet substrates. The first sheets and / or second sheets are connected by multiple triangular contacts on the side. The first sheets and second sheets can be disassembled by cutting the contacts, and then the assembly can be completed.

[0068] Based on the above description of specific embodiments, the folding fan with unfolding and closing connection structure between metal assembly model sheets and its manufacturing process provided by this utility model has the following advantages compared with the prior art:

[0069] First, the sheet has a horizontally arranged groove and a bendable clip. Between two adjacent sheets, the bendable clip on one passes through the groove on the other and bends to fit together, forming an unfolding and closing connection structure between the sheets. One sheet can slide along the rail of another sheet via its clip, thus unfolding or closing, giving the metal model toy functionality and improving the user experience. The sliding connection structure, composed of the groove and the bendable clip, is simple in structure and easy to assemble.

[0070] Secondly, for metal folding fan products, each fan blade unit is formed by the relative bonding and fixing of a first sheet and a second sheet. The upper part of the first sheet has a perforated window, and a bendable clip is provided on one vertical side of the window. The second sheet has an arc-shaped slide rail at the position corresponding to the window of the first sheet. Two adjacent fan blade units form a sliding connection structure through the bendable clip. One fan blade unit can slide in the arc-shaped slide rail of the other fan blade unit through the clip, realizing the opening or closing of the two fan blade units. In addition to being decorative, it also has functionality and interactivity, improving the user experience. The sliding connection structure between each fan blade unit is simple in structure and quick and convenient to assemble.

[0071] Third, it adopts a sheet assembly structure, retaining the fun of assembling models that encourages hands-on learning and intellectual development. Through a rational layout, multiple sheets are formed on a single sheet base, saving materials and reducing costs. Furthermore, the entire sheet can be transferred during production, eliminating the need to collect individual sheets and improving production efficiency.

[0072] Fourth, the top of the first sheet is provided with two upper splicing pins spaced apart, and the second sheet is provided with upper insertion holes corresponding to the upper splicing pins. The two horizontal sides of the window are provided with four bendable middle splicing pins, and the second sheet is provided with middle insertion holes corresponding to the middle splicing pins. The first and second sheets are fixed by inserting the splicing pins into the insertion holes and bending them. The structure is simple and easy to assemble.

[0073] Fifth, four bendable central splicing pins are set on the two horizontal sides of the window. The four central splicing pins are set opposite each other in pairs, with two of the central splicing pins set directly opposite the root of the clip. This optimized layout is reasonable and simplifies the design and manufacturing of the sheet.

[0074] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0075] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
