Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and in particular to a vector engine nozzle structure for a fighter jet model. Background Technology

[0002] Fighter jet models are models made according to a certain scale or in the same style as real fighter jets. They play an important role in aviation science popularization, military education, collection and entertainment. Since the engine is the heart of the fighter jet and a key factor affecting its performance, the vector engine nozzle structure is an important part of engine technology.

[0003] Currently available fighter jet model engines on the market are mostly designed for static display. Key components of vector engines are often fixed in place, primarily serving the viewing and collection needs of enthusiasts. They lack advanced functions such as dynamic interaction and in-depth demonstration, which limits the user experience and fails to provide accurate reference for scientific research and popular science, thus failing to meet the needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nozzle structure for a vector engine of a fighter jet model, aiming to improve the problem that the nozzle structure for a vector engine of a fighter jet model is inconvenient to adjust during display, thus failing to provide accurate reference for popular science.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vector engine nozzle structure for a fighter jet model, comprising a fuselage, a first connector on the right side of the fuselage, a second connector on the right side of the first connector, a connecting block on the right side of the second connector, and a tail nozzle connector on the right side of the connecting block. Each of the first connector, the second connector, the connecting block, and the tail nozzle connector has a placement slot on one side. A miniature magnet is fixedly connected inside each of the multiple placement slots. The first connector, the second connector, the connecting block, and the tail nozzle connector are connected to each other via the miniature magnets.

[0006] As a further description of the above technical solution:

[0007] A protective cover is fixedly connected to the right side of the outer wall of the tail nozzle connector, and multiple inclined grooves are equidistantly opened on the outer side of the protective cover.

[0008] As a further description of the above technical solution:

[0009] A limiting block is fixedly connected to the top inner side of the body, and a limiting groove is fixedly connected to the top inner side of the first connector. The limiting block and the limiting groove are inserted into each other.

[0010] As a further description of the above technical solution:

[0011] A limiting cone is fixedly connected to the middle right side of the connecting block, and the limiting cone is inserted into the corresponding placement groove.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, since the oblique angles of the first connector, the second connector, and the tail nozzle connector are all different, rotating the tail nozzle connector causes it to reach the limit position with the second connector under the action of the micro magnet. Then, continuing to rotate the tail nozzle connector allows it to be locked in place by the angle between the second connector and the first connector. The second connector and the first connector can rotate together. Based on their oblique angles, the tail nozzle vector transfer effect can be achieved, thus providing accurate reference for scientific research and popular science, and meeting the needs of users.

[0019] 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.

[0020] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a vector engine nozzle structure for a fighter jet model, including a fuselage 1. A first connector 2 is provided on the right side of the fuselage 1, a second connector 3 is provided on the right side of the first connector 2, a connecting block 5 is provided on the right side of the second connector 3, and a tail nozzle connector 6 is provided on the right side of the connecting block 5. A placement groove 4 is provided on one side of the first connector 2, the second connector 3, the connecting block 5, and the tail nozzle connector 6. A miniature magnet 8 is fixedly connected inside the multiple placement grooves 4. The first connector 2, the second connector 3, the connecting block 5, and the tail nozzle connector 6 are connected to each other through the miniature magnet 8. A protective cover 9 is fixedly connected to the right side of the outer wall of the tail nozzle connector 6. Multiple inclined grooves 10 are equidistantly provided on the outer side of the protective cover 9.

[0021] Specifically, with the assistance of the micro magnet 8, the rotating tail nozzle connector 6 can ensure that the tail nozzle connector 6 and the second connector 3 can smoothly reach the predetermined limit position. Once the tail nozzle connector 6 and the second connector 3 are correctly aligned and reach the limit, the tail nozzle connector 6 continues to rotate. Through the preset angle limit positioning between the second connector 3 and the first connector 2, the linkage rotation of the second connector 3 and the first connector 2 can be realized, so that the tail nozzle vector transfer effect can be realized, thereby ensuring that the user can obtain an accurate and intuitive experience.

[0022] Reference Figure 3 A limiting block 11 is fixedly connected to the top inner side of the body 1, and a limiting groove 12 is fixedly connected to the top inner side of the first connecting piece 2. The limiting block 11 and the limiting groove 12 are inserted into each other.

[0023] Specifically, the connection between the body 1 and the first connecting member 2 can be further improved by inserting the limiting block 11 into the limiting groove 12.

[0024] Reference Figure 2 A limiting cone 7 is fixedly connected to the middle right side of the connecting block 5, and the limiting cone 7 is inserted into the corresponding placement groove 4.

[0025] Specifically, the limiting cone 7 can further improve the connection stability between the connecting block 5 and the tail nozzle connector 6.

[0026] Working principle: When it is necessary to adjust the tilt angle of this structure, first rotate the tail nozzle connector 6. With the assistance of the micro magnet 8, it can be ensured that the tail nozzle connector 6 and the second connector 3 can smoothly reach the predetermined limit position. Once the tail nozzle connector 6 and the second connector 3 are correctly aligned and reach the limit, continue to rotate the tail nozzle connector 6. Through the preset angle limit locking between the second connector 3 and the first connector 2, the linkage rotation of the second connector 3 and the first connector 2 can be realized. This linkage mechanism is based on the precisely designed oblique angle between them, so that the tail nozzle vector transfer effect can be realized. This operation not only provides accurate reference data for the scientific research field, but also meets the needs of dynamic demonstration in popular science education, ensuring that users can obtain an accurate and intuitive experience.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
