[0002] An airplane model is a model that is scaled down in size based on the image of an airplane. It is generally divided into two types, dynamic and static. The static one is used for collection, display, etc. and cannot fly; the dynamic one can fly and can be controlled by remote control or other means.

[0003] The control surface adjustment structure of model airplanes varies depending on the type of model, but generally speaking, the control surface adjustment structure is composed of a number of parts and fasteners. Each control surface is divided into ailerons, flaps, rudder, and elevator. Each control surface has its own function and provides adjustment functions for various flight attitudes of the aircraft.

[0004] Problems with existing technologies:

[0005] Some model aircraft rudder adjustment structures may have some problems, such as loose parts, stuck or malfunctioning rudders, etc. These problems may cause the stability of the model aircraft to decrease, so they need to be frequently maintained and serviced during later use. During the maintenance process, especially during the disassembly and installation of the model aircraft rudder adjustment structure, it is easy to cause the sockets for connecting the connecting rods to wear and expand, and the disassembly process is more difficult.

[0029] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0030] like Figure 1-3 As shown, a model aircraft control surface adjustment structure includes a model aircraft body 1, a motor 2 and a connecting rod 3. The motor 2 is fixedly installed inside the model aircraft body 1 by screws, and the motor 2 is connected to multiple ailerons 11, elevators 12 and rudders 13 provided on the model aircraft body 1 through the connecting rod 3.

[0031] Among them, the two ends of the connecting rod 3 are respectively connected with rings 33, the ends of the rings 33 are movably clamped with the ends of the connecting rod 3, the ends of the connecting rod 3 are magnetically connected to the rings 33, one end of the connecting rod 3 is plugged with a connector 4 through the ring 33, and the connector 4 is fixedly installed on the aileron 11, the elevator 12 and the rudder 13.

[0032] In addition, a "U"-shaped structure is provided on the connecting rod 3, and the motor 2, multiple ailerons 11, elevators 12 and rudders 13 at both ends of the connecting rod 3 are elastically connected through the "U"-shaped structure. The "U"-shaped structure can provide elastic buffering for the connecting rod 3 during the stretching process, and the "U"-shaped structure is used to reset the multiple ailerons 11, elevators 12 and rudders 13 after they are rotated. The elastic buffering is used to improve the installation stability of the multiple ailerons 11, elevators 12 and rudders 13, and avoid damage to the model aircraft body 1 when the multiple ailerons 11, elevators 12 and rudders 13 are subjected to strong impact or bending.

[0033] Furthermore, a mounting hole 41 for inserting the collar 33 is formed through the bottom surface of the connector 4 , and a retaining ring 34 for abutting against one side of the mounting hole 41 is provided on the side of the collar 33 facing away from the spring sheet 35 .

[0034] Furthermore, a connecting end 31 for inserting the sleeve ring 33 is provided at the end of the connecting rod 3 , and an expanding end 32 is provided at the end of the connecting end 31 , and the spring piece 35 is elastically engaged with one end of the expanding end 32 .

[0035] According to the above structure, its working principle is:

[0036] It is connected to the aileron 11, the elevator 12 and the rudder 13 through the motor 2 at the bottom of the model aircraft body 1, and further through its movably connected connecting rod 3, and through the rotation of the motor 2, the connecting rod 3 is driven to stretch the aileron 11, the elevator 12 and the rudder 13, so that the aileron 11, the elevator 12 and the rudder 13 produce hinged movement. However, as the number of times the motor 2 drags the connecting rod 3 to move increases, and during the daily maintenance and cleaning process, the motor 2, the connecting rod 3 and the connecting piece 4 need to be removed to clean the debris generated during the movement. During the operation and disassembly process, the plug-in parts at both ends of the connecting rod 3 will become loose, thereby causing a jam in the subsequent operation process.

[0037] Therefore, by installing a ring 33 inside the connecting member 4, the direct friction between the end of the connecting rod 3 and the connecting member 4 is reduced, and the magnetic connection between it and the ring 33 can prevent the end of the connecting rod 3 from falling off, and the end of the connecting rod 3 can be quickly disassembled, while the number of bending times of the end of the connecting rod 3 is reduced. Therefore, in the process of disassembling the end of the connecting rod 3, disassembly and installation are more convenient, and the wear on the connecting member 4 during the disassembly process is reduced.

[0038] In addition, when installing the ring 33, through its elastic connection with the end of the expanded end 32, the diameter of the middle part of the spring piece 35 increases and expands, and the expanded part of the spring piece 35 blocks the other side of the mounting hole 41. At this time, it can prevent the connecting rod 3 and the connecting piece 4 from falling off during the movement, thereby achieving the installation stability of the structure.

[0039] Please refer to Figure 1 and Figure 2 As shown, the ailerons 11 are hinged on both sides of the middle of the model aircraft body 1 , the elevators 12 are hinged on both sides of the tail of the model aircraft body 1 , and the rudder 13 is hinged on the tail end of the model aircraft body 1 .

[0040] Furthermore, the motor 1 2 also includes a motor 2 21 fixed to the bottom of the model aircraft body 1 by screws, and the motor 2 21 is connected to the elevator 12 and the rudder 13 through the connecting rod 3.

[0041] According to the above structure, the main body of the motor 1 2 brakes and articulates the ailerons 11 on both sides through the output shaft, and drives the elevator 12 and the rudder 13 to articulate through the output shaft of the motor 2 21 .

[0042] Please refer to Figure 3 As shown, the connector 4 includes a side toothed rod 42 at the top for plugging into the surfaces of the aileron 11, the elevator 12 and the rudder 13. An inner toothed collar 43 is sleeved on the outer side of the side toothed rod 42. The side toothed rod 42 and the inner toothed collar 43 are interference fit. By disassembling the inner toothed collar 43 and the side toothed rod 42, quick disassembly and installation of the connector 4 can be achieved.

[0043] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
