Description

Technical Field

[0001] This utility model relates to the field of aircraft model technology, and in particular to an aircraft model wing quick-assembly structure and an aircraft model. Background Technology

[0002] Model aircraft is a general term for various aircraft models. It includes model airplanes and other model flying machines. To save space and prevent damage during transportation and packaging, the wings of model aircraft are usually removed before packaging and transport to ensure their safety.

[0003] To quickly remove the wings from the fuselage, quick-release mechanisms are usually installed. However, some quick-release mechanisms are fastened together by hooks. The hook design is subject to force on one side, resulting in poor stability.

[0004] For example, Chinese patent application number CN202321074570.6 discloses a quick-release mechanism for the wing of a model airplane. Specifically, it discloses that "a locking block has an inclined surface on the side opposite to the spring; two locking blocks are symmetrically arranged; and two guide posts have slots on opposite sides for the inclined surface to engage. During locking block assembly, the spring is sleeved on the locking block's sleeve rod, then the locking block housing is installed, the cover plate is placed, and then screws are used to tighten it. Then, the two blocks are installed together with the fixing component and tightened with screws. After the two locking blocks are assembled, they are then installed onto the main wing along with the fixing component." The locking block has an inclined surface forming the first barb; the guide post has a slot forming the second barb. This design uses barbs to engage the blocks, but this design results in unilateral force application and relatively poor stability. Utility Model Content

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Example 1 Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a quick-assembly structure for a model aircraft wing.

[0028] The locking member 13 has a latch 14 that engages with the connecting post 22. This design allows the connecting post 22 to be subjected to force at multiple locations, resulting in a more balanced force distribution. The locking member 13 and the connecting post 22 will not come loose, and the stability is better.

[0029] This application provides a quick-release structure for a model aircraft wing, including a first connecting device 10 disposed on the fuselage and a second connecting device 20 disposed on the wing. The first connecting device 10 includes a first connecting seat 11 and a locking member 13 slidably disposed on the first connecting seat 11. The second connecting device 20 includes a second connecting seat 21 and a connecting post 22 disposed on the second connecting seat 21. The first connecting seat 11 and the second connecting seat 21 are closed together. The connecting post 22 is inserted into the locking member 13, and the latch 14 of the locking member 13 engages the connecting post 22. The connecting post 22 is provided with an annular groove 23; the latch 14 engages with the annular groove 23. The first connecting seat 11 and the second connecting seat 21 can be manufactured using injection molding, die casting, or stamping processes. The first connecting seat 11 can be fixed to the fuselage with screws; the second connecting seat 21 can be fixed to the wing with screws. During wing and fuselage assembly, the first connecting seat 11 and the second connecting seat 21 close together, pushing the locking member 13 so that the latch 14 of the locking member 13 engages the connecting post 22. This assembly structure is simple and convenient. The connecting post 22 is cylindrical, and the latch 14 matches the annular groove 23. Therefore, when the latch 14 of the locking member 13 engages the connecting post 22, the force on the connecting post 22 is more even, with multi-sided force distribution, eliminating the problem of loosening and improving its stability.

[0030] Preferably, the locking member 13 is provided with a lever 15, which extends through a groove 12 on the first connecting seat 11; an elastic buckle 17 is provided on the side of the locking member 13; the locking member 13 has a locking head 16, which is inserted into the elastic buckle, and the locking port 18 of the elastic buckle 17 can lock the locking head 16. The lever 15 facilitates the operation of the locking member 13. The elastic buckle 17 can lock the locking head 16. When the wing and fuselage are assembled, the elastic buckle locks the locking head 16, thus fixing the position of the locking member 13. When the locking member 13 is manually pushed again, the locking member 13 will be unlocked, that is, the locking member 13 can be separated from the connecting post 22. This design is very simple and efficient, and the assembly is also very convenient.

[0031] Preferably, the end of the locking head 16 is trapezoidal or spherical; the elastic buckle 17 is a press-type elastic buckle. When the locking head 16 is inserted into the elastic buckle 17, the locking head 16 is locked; when the lever 15 is pushed again, the locking head 16 is unlocked. Specifically, the elastic buckle 17 can be a beetle-shaped elastic buckle 17 or a press-type plastic elastic buckle 17, or other types of rebound elastic buckles 17. Therefore, the locking head 16 and the elastic buckle 17 form a locking structure similar to a rebound mechanism. That is, the first push of the lever 15 locks the locking head 16 and the elastic buckle 17; the second push of the lever 15 unlocks the locking head 16 and the elastic buckle 17.

[0032] Preferably, the second connector 21 is provided with a mounting hole 24; the connecting post 22 is inserted into the mounting hole 24; and the first screw 25 fixes the connecting post 22 in the mounting hole 24. This design can position the connecting post 22, and the first screw 25 fixes the connecting post 22 in the mounting hole 24, making the structure more robust.

[0033] Preferably, a connector 30 is further provided between the first connecting device 10 and the second connecting device 20; the connector 30 includes a male head 320 and a female head 310; the female head 310 is provided in the first connecting device 10 and the male head 320 is provided in the second connecting device 20; the female head 310 includes a first housing 311 and a first terminal module 315 that can be plugged into the first housing 311. The male connector 320 includes a second housing 321 and a second terminal module 324 that is pluggably disposed within the second housing 321. The first housing 311 and the second housing 321 can be closed together. The second terminal module 324 can be inserted into the first housing 311 and is in communication with the first terminal module 315. The female connector 310 and the male connector 320 can be fixed in their respective positions using screws. The screws are tightened onto the first housing 311 and the second housing 321 to complete the installation. There are multiple first terminal modules 315 and second terminal modules 324; the specific number can be set according to needs. This design makes the layout more flexible, allowing users to select connectors 30 with different numbers of interfaces as needed.

[0034] Preferably, the first housing 311 has a first insertion hole 312 inside, and a first limiting block 313 is provided on the inner wall of the first insertion hole 312; the first terminal module 315 has a first limiting groove 316; the first terminal module 315 is inserted into the first insertion hole 312, and the first limiting block 313 is embedded in the first limiting groove 316. The first terminal module has a first step 317; the first step 317 is blocked by the first housing 311 at the opening of the first insertion hole. When the first terminal module 315 is inserted into the first insertion hole 312, the first limiting block 313 is embedded in the first limiting groove 316, so that the first terminal module 315 is limited and will not come loose. Meanwhile, the first step 317 is blocked at the opening of the first socket by the first housing 311, which can control the length of the first terminal module 315 inserted into the first socket 312 and make the first terminal module 315 firmly installed. The first limiting block 313, the first limiting groove 316, and the first step 317 work together to ensure assembly accuracy.

[0035] Preferably, the second outer casing 321 has a second insertion hole 322 inside, and a third step 323 is provided inside the second insertion hole 322. The second terminal module 324 has a fourth step 325. The third step 323 is blocked by the fourth step 325. The spring piece 326 on the second outer casing 321 abuts against the second terminal module 324. The second terminal module 324 is inserted into the first insertion hole 312 and the second insertion hole 322. When the second terminal module 324 is inserted into the second insertion hole 322, the third step 323 is blocked by the fourth step 325, which can control the insertion depth of the second terminal module 324 and ensure good installation accuracy. The spring piece 326 abuts against the second terminal module 324, which fixes the second terminal module 324, making it very convenient to install and remove. The insertion of the second terminal module 324 into the first insertion hole 312 and the second insertion hole 322 also enhances the installation firmness between the fuselage and the wing. The first terminal module and the second terminal module 324 are injection molded terminals, formed by encapsulating the terminals with injection molding plastic.

[0036] Example 2 Example 2 includes the quick-assembly structure for model aircraft wings described in Example 1. A model aircraft includes the aforementioned quick-assembly structure for model aircraft wings; at least two second connecting devices 20 are provided on the wing; and the locking directions of the locking members 13 are opposite; therefore, the first connecting seats 11 on the fuselage correspond one-to-one with the second connecting devices 20; landing gear is provided at the bottom of the fuselage. With the quick-assembly structure for model aircraft wings, the connection strength between the wing and the fuselage is better, and the robustness is more reliable.

[0037] In summary, the key design feature of this invention is that, during the assembly of the wing and fuselage, the first connecting seat 11 and the second connecting seat 21 are closed together; the latch 14 of the locking member 13 engages the connecting post 22. Because the latch 14 of the locking member 13 is engaged with the connecting post 22, the connecting post 22 is subjected to force as a whole, resulting in a more balanced force distribution. Furthermore, there is no issue of the locking member 13 and the connecting post 22 becoming loose, leading to better stability.
