Description

Technical Field

[0001] This utility model relates to the field of simulated aircraft model technology, and in particular to a simulated aircraft model wing structure. Background Technology

[0002] A simulated aircraft model is a scaled-down replica of a real aircraft, meticulously replicating its exterior details, paint scheme, and even internal structure. Its core objective is realism. Simulated models are primarily intended for static display, used for collection, exhibition, and education, and are generally not meant to be flown.

[0003] Current simulated aircraft models are mostly pieced together, constructed from components such as the fuselage, wings, tail, and landing gear. Their internal framework is built with balsa wood or carbon fiber, then covered with a thin film to create a smooth outer surface. However, the current wing-to-fuselage connection structure mostly uses bolts. Because the material is mostly balsa wood, bolted connections lead to stress concentration. Furthermore, balsa wood has low density, is brittle, and has weak fiber strength. The screw threads cannot effectively "grip" the wood, making them very prone to stripping and loosening. Under stress, the wood around the screw is easily torn or crushed. Therefore, an improvement in the connection method is needed. Utility Model Content

[0004] Therefore, it is necessary to provide a simulated aircraft model wing structure to address the above problems.

[0005] A simulated aircraft model wing structure includes a fuselage and a wing. An extension is provided on the side of the fuselage, and a fitting part is provided at one end of the wing that connects to the fuselage. The fitting part is fitted onto the outside of the extension, and the extension and the fitting part are connected and sealed by glue.

[0006] Preferably, the fitting part is provided with a glue inlet, the extension part is provided with an annular groove, and the glue inlet is directly opposite the annular groove.

[0007] Preferably, there are two annular grooves arranged side by side, and the two annular grooves are connected by a notch.

[0008] Preferably, the edges of the extension and the sleeve are provided with rubber sealing rings.

[0009] Preferably, the adhesive injected between the extension and the sleeve is PU foam.

[0010] Preferably, the end of the sleeve portion is provided with a groove, and the extension portion is provided with a protrusion corresponding to the groove.

[0011] The advantages of this utility model are: the extension part and the fitting part are connected by glue pouring, which eliminates the need for screws, and the glue fills the gap between the extension part and the fitting part during the glue pouring process, making it less likely to overflow and preventing the glue from sticking to the fuselage or wings and being difficult to clean.

[0013] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] like Figures 1-3As shown, a simulated aircraft model wing structure includes a fuselage 1 and a wing 2. An extension 11 is provided on the side of the fuselage 1. A fitting 12 is provided at one end of the wing 2 connected to the fuselage 1, and the fitting 12 is fitted over the extension 11. The extension 11 and the fitting 12 are sealed together by glue. Specifically, in this embodiment, the fuselage 1 and wing 2 are made of balsa wood and covered with a skin. A solid extension 11 is provided on the side of the fuselage 1 to enhance structural strength. The extension 11 is elliptical in shape. The fitting 12 is provided at the inner end of the wing 2 and fits onto the extension 11. At this point, there is a gap between the fitting 12 and the extension 11, making it relatively loose. Therefore, the applicant uses glue to connect the extension 11 and the fitting 12, eliminating the need for screws. Furthermore, during glue application, the glue fills the gap between the extension 11 and the fitting 12, preventing overflow and avoiding glue sticking to the fuselage or wing, which would be difficult to clean.

[0017] like Figures 2-3 As shown, the fitting part 12 is provided with a glue inlet 121, and the extension part 11 is provided with an annular groove 111, with the glue inlet 121 facing the annular groove 111. Specifically, when the extension part 11 is inserted into the filling part 12, glue is injected into the glue inlet 121. Under pressure, the glue fills the annular groove 111, thereby bonding the fitting part 12 and the extension part 11 together. The glue injection operation is simple and convenient. After the injection is completed, the glue inlet 121 is sealed with a wooden stopper to prevent uncured glue from overflowing from the glue inlet 121.

[0018] like Figure 3 As shown, there are two annular grooves 111 arranged side by side, and the two annular grooves 111 are connected by a notch 112. Only one glue inlet 121 needs to be opened on the fitting part 12 to fill multiple annular grooves 111. At the same time, after the glue in one annular groove 111 is full, it can overflow into another annular groove 111 through the notch 112.

[0019] like Figure 3 As shown, the edges of the extension 11 and the sleeve 12 are provided with rubber sealing rings 13. When the sleeve 12 wraps around the extension 11, the rubber sealing rings 13 on the sleeve 12 and the extension 11 are located on both sides of the glue-filled annular groove 111. The rubber sealing rings 13 are deformed under pressure, sealing the gap between the extension 11 and the sleeve 12 to prevent glue from overflowing during glue pouring.

[0020] Specifically, the adhesive injected between the extension 11 and the sleeve 12 is PU foam.

[0021] like Figures 2-3As shown, the end of the fitting part 12 is provided with a groove 122, and the extension part 11 is provided with a protrusion 113 corresponding to the groove 122. Specifically, during assembly, the extension part 11 is inserted into the fitting part 12, and the groove 122 and the protrusion 113 are aligned and inserted, cooperating with each other to play a positioning and limiting role.

[0022] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
