Description

Technical Field

[0001] This utility model relates to the field of model aircraft assembly, and in particular to a modular quick-release structure based on 3D printing molding technology. Background Technology

[0002] Modern model airplanes, whether installing wings or horizontal stabilizers, require structural matching with the fuselage. If a small number of parts are needed, tools will inevitably be required during assembly, such as direct screw fastening. In this case, the number of molds is small, but the mold structure is complex and the cost is high. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0004] A modular quick-release structure based on 3D printing molding technology, including a body;

[0005] The fuselage is equipped with wings on both the left and right sides, and there are connecting mechanisms between the fuselage and the wings.

[0006] The connecting mechanism includes a first connecting block that is connected to the fuselage and a second connecting block that is connected to the wing. The front and rear sides of the first connecting block are respectively formed with a first limiting groove, which is a teardrop-shaped structure arranged laterally.

[0007] The front and rear sides of the second connecting block are respectively formed with rotating grooves. A rotating rod is rotatably arranged inside the rotating groove. A limiting block is set on the side of the rotating rod near the first limiting groove. The limiting block has a teardrop-shaped structure arranged horizontally. After the rotating rod drives the limiting block to pass through the first limiting groove, the rotating rod rotates to achieve mutual limiting and cooperation between the limiting block and the first limiting groove.

[0008] As a further embodiment of this utility model: a second limiting groove is provided on the side of the lower end of the rotating groove near the limiting block, and a lever is provided on the other end of the rotating rod. The lever of the same rotating rod and the limiting block are arranged in opposite directions.

[0009] As a further embodiment of this utility model: the first connecting block, the second connecting block, the rotating rod, the limiting block, and the lever are all integrally formed by 3D printing.

[0010] As a further embodiment of this utility model: a receiving groove for the limiting block is provided on the side of the rotating groove near the first limiting groove, and the inner rings of the receiving groove and the first limiting groove are respectively formed with chamfers.

[0011] As a further embodiment of this utility model: mounting blocks are respectively provided on the side of the first connecting block near the fuselage and the side of the second connecting block near the wing, and mounting grooves are respectively provided on the side of the fuselage near the first connecting block and the side of the wing near the second connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a first connecting block, a second connecting block, a rotating rod, and a limiting block, the rotating rod drives the limiting block to move towards one side of the first limiting groove in the rotating groove. After the limiting block passes through the first limiting groove, rotating the rotating rod makes the limiting block and the first limiting groove mutually limit and cooperate, realizing the connection between the wing and the fuselage; by adopting 3D printing molding process combined with tool-free assembly disassembly structure, parts that previously required post-assembly can be processed at one time, and the assembly of the molded parts is also completed. This saves a lot of mold involvement and can also achieve a sophisticated structure.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Please see Figure 2-7 A modular quick-release structure based on 3D printing molding technology, including a body 1;

[0027] Wings 2 are provided on the left and right sides of the fuselage 1, and connecting mechanisms 3 are provided between the fuselage 1 and the wings 2 respectively;

[0028] The connecting mechanism 3 includes a first connecting block 4 that is connected to the fuselage 1 and a second connecting block 5 that is connected to the wing 2. The front and rear sides of the first connecting block 4 are respectively formed with a first limiting groove 6, which is a teardrop-shaped structure arranged laterally.

[0029] The front and rear sides of the second connecting block 5 are respectively formed with rotating grooves 7. A rotating rod 8 is rotatably arranged inside the rotating groove 7. A limiting block 9 is arranged on the side of the rotating rod 8 near the first limiting groove 6. The limiting block 9 has a teardrop-shaped structure arranged horizontally. After the rotating rod 8 drives the limiting block 9 to pass through the first limiting groove 6, the rotating rod 8 rotates to realize the mutual limiting cooperation between the limiting block 9 and the first limiting groove 6.

[0030] In use, the first connecting block 4 is connected to the fuselage 1, and the second connecting block 5 is connected to the wing 2. Then, the first connecting block 4 and the second connecting block 5 are fitted together. The rotating rod 8 drives the limiting block 9 to move towards the first limiting groove 6 in the rotating groove 7. After the limiting block 9 passes through the first limiting groove 6, the rotating rod 8 is rotated to make the limiting block 9 and the first limiting groove 6 mutually limit and cooperate.

[0031] A further solution: A second limiting groove 10 is provided on the side of the lower end of the rotating groove 7 near the limiting block 9, and a lever 11 is provided on the other end of the rotating rod 8. The lever 11 of the same rotating rod 8 and the limiting block 9 are arranged in opposite directions.

[0032] It is easy to use the lever 11 to drive the rotating rod 8 to rotate, so that the limiting block 9 rotates at the first limiting groove 6, realizing the limiting engagement between the limiting block 9 and the first limiting groove 6, and ensuring a tight connection between the fuselage 1 and the wing 2.

[0033] A further solution: The first connecting block 4, the second connecting block 5, the rotating rod 8, the limiting block 9, and the lever 11 are all 3D printed as a single unit.

[0034] The parts that previously required post-assembly can be manufactured in one go, and the assembly of the parts is completed at the same time. This saves a lot of molds and can achieve ingenious structures, thus improving work efficiency.

[0035] A further solution: The rotating groove 7 is provided with a receiving groove 12 for the limiting block 9 to be installed on the side near the first limiting groove 6. The inner rings of the receiving groove 12 and the first limiting groove 6 are respectively formed with chamfers 13.

[0036] This allows the limiting block 9 to pass through the first limiting groove 6, improving assembly efficiency.

[0037] A further solution: Mounting blocks 14 are respectively provided on the side of the first connecting block 4 near the fuselage 1 and the side of the second connecting block 5 near the wing 2, and mounting slots 15 are respectively provided on the side of the fuselage 1 near the first connecting block 4 and the side of the wing 2 near the second connecting block 5.

[0038] The connection between mounting block 14 and mounting slot 15 facilitates a tight connection between the first connecting block 4 and fuselage 1, and between the second connecting block 5 and wing 2.

[0039] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof 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.
