Technical Field

[0001] This utility model belongs to the field of popular science demonstration technology, specifically to a rotating demonstration disk for aircraft runway numbering. Background Technology

[0002] The numbering of aircraft runways is an important system in the aviation field used to identify and distinguish different runways. Its design is based on the Earth's magnetic direction and azimuth, and has clear rules and practical significance.

[0003] In some science and technology exhibition halls, when explaining the knowledge related to aircraft runway numbering, mini airport sand table models are usually used. This method is relatively abstract and not intuitive, and its function is limited. It can only explain the angle numbers corresponding to a certain section or two sections of the runway, and it is also relatively abstract. Utility Model Content

A first fixed ring is fixedly arranged on the base plate, and a first rotating ring is rotatably sleeved on the outer side of the first fixed ring. A disk is connected to the first rotating ring, and a runway indication area is provided on the disk. Windows for displaying two relative runway numbers are provided at both ends of the runway indication area.

[0006] Preferably, a second fixing ring is fixedly disposed on the base plate, located outside the runway number and coaxial with the first fixing ring. A second rotating ring is rotatably sleeved on the outside of the second fixing ring. An annular disk located outside the disc is connected to the second rotating ring, and left and right marking areas are disposed opposite each other on the annular disk.

[0007] Preferably, the first rotating ring and the disk, and the second rotating ring and the annular disk are both connected by screws.

[0008] Preferably, the first fixed ring is in rolling contact with the first rotating ring, and the second fixed ring is in rolling contact with the second rotating ring.

[0009] Preferably, the base plate is circular, and the outer edge of the second rotating ring is aligned with the outer edge of the base plate.

[0010] Preferably, the base plate, disc, and annular disc are made of aluminum alloy.

[0011] Preferably, the base plate is provided with a connecting plate, and the connecting plate has connecting holes.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: Rotate the disc to make the runway indication area rotate, and at the same time, two windows will display the two runway numbers, indicating the number of one end of the runway and the number of the other end, which makes it easier to explain and understand the angle numbers corresponding to multiple runways.

[0019] The following is combined with Figure 1 and Figure 2 This utility model will be described in detail.

[0020] Example A demonstration rotating disk for aircraft runway numbering includes a base plate 1, on which several runway numbers 6 are arranged circumferentially. A first fixing ring 10 is fixedly arranged on the base plate 1, and a first rotating ring 11 is rotatably sleeved on the outer side of the first fixing ring 10. A disk 2 is connected to the first rotating ring 11, and a runway indication area 5 is provided on the disk 2. Windows 4 for displaying two opposite runway numbers 6 are provided at both ends of the runway indication area 5.

[0021] The disc 2 can rotate relative to the base plate 1 through the cooperation of the first fixed ring 10 and the first rotating ring 11, thereby causing the runway indication area 5 to rotate. At the same time, the two windows 4 display the two runway numbers 6, that is, indicate the number of one end of the runway and the number of the other end, so as to facilitate the explanation and understanding of the angle numbers corresponding to multiple runways.

[0022] Specifically: Runway numbers are named according to the magnetic azimuth of the local airport runway, which also indicates the direction of aircraft movement. The basic principle of naming is to take the first two digits of the runway's magnetic azimuth (rounded down, so there may be runways with the same name but different directions). Since the difference in magnetic azimuth between the two ends of a runway is 180 degrees, for a two-way runway, simply adding or subtracting 18 from the number at one end of the runway will give you the number at the other end. Figure 1 As shown in the diagram, if the aircraft enters the runway from left to right, the runway number is 07; if the aircraft enters the runway from right to left, the runway number is 25.

[0023] A second fixing ring 12, located outside of runway number 6 and coaxial with the first fixing ring 10, is fixedly installed on the base plate 1. A second rotating ring 13 is rotatably sleeved on the outside of the second fixing ring 12. An annular disk 3, located outside the disc 2, is connected to the second rotating ring 13. Left and right marking areas 9 are arranged opposite each other on the annular disk 3. The left and right marking areas 9 are used to distinguish the left or right end of the runway. That is, after the disc 2 stops rotating, the annular disk 3 is rotated as needed to align the left and right marking areas 9 with the ends of the runway indication area 5.

[0024] The first rotating ring 11 and the disc 2, and the second rotating ring 13 and the annular disc 3 are all connected by screws. The screw connection is a detachable connection method, which facilitates the disassembly and replacement of the disc 2 and the annular disc 3.

[0025] The first fixed ring 10 and the first rotating ring 11 are in rolling contact, and the second fixed ring 12 and the second rotating ring 13 are in rolling contact. Rolling contact reduces relative rotational friction, decreases rotational resistance, and ensures smooth rotation. The fixed rings and rotating rings can form a bearing structure to achieve rolling contact; at the same time, using a bearing structure also prevents the fixed rings and rotating rings from separating.

[0026] The base plate 1 is circular, and the outer edge of the second rotating ring 13 is aligned with the outer edge of the base plate 1, so that the operator can have a good grip when holding the entire rotating disk.

[0027] The base plate 1, the circular disc 2, and the annular disc 3 are made of aluminum alloy. Aluminum alloy has high structural strength and is lightweight, which reduces the overall weight while ensuring the service life of the rotating disc and making it easy to hold.

[0028] A connecting plate 7 is provided on the base plate 1, and a connecting hole 8 is provided on the connecting plate 7. After the connecting hole 8 is provided, it can be fixed to other equipment as needed.

[0029] The runway indication area 5, runway number 6, and left and right marking areas 9 are set on the corresponding structures using heat-printed acrylic.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
