Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft instrument demonstration, and in particular relates to an aircraft instrument teaching demonstration device. Background Art

[0002] Aircraft instruments are important equipment for pilots to control and monitor the status of aircraft. They include various indicators, dashboards, switches, buttons, etc., which reflect the speed, altitude, direction, fuel level, temperature, pressure and other information of the aircraft. The design and use of aircraft instruments involve knowledge in multiple fields such as aeronautical engineering, electronic engineering, mechanical engineering, and human-computer interaction. For pilots and aviation enthusiasts, they have high learning value and practicality.

[0003] In order to allow more people to understand and learn about aircraft instruments, some civil airliners and military aircraft will transport some of their instruments to colleges or museums after retirement for people to visit or as teaching equipment for students to learn and practice;

[0004] However, the current instrument display method has some shortcomings, mainly in the following two aspects:

[0005] The display effect of the instrument is not good. Since the instrument is relatively small, it is easy for the observer to not observe it carefully and clearly and cannot feel the real size and details of the instrument when it is placed directly in the glass display cabinet.

[0006] The teaching effect of the instrument is not strong. Since the instrument is only a static display, its display effect is relatively simple and not attractive enough to the observer;

[0007] Therefore, in view of the above problems, the purpose of the present invention is to provide an aircraft instrument teaching demonstration device to avoid the above problems. Utility Model Content

[0024] 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.

[0025] like Figure 1-3 As shown, an aircraft instrument teaching demonstration device includes a base 1, and a plurality of drawers 13 are arranged inside the base 1. Through the arrangement of the drawers 13, a user can store a plurality of different types of aircraft instrument bodies 5 in the drawers 13, and can store other important objects in the drawers 13. A universal wheel 14 is installed at the four end corners of the bottom of the base 1. Through the arrangement of the universal wheel 14, when the user needs to move the device, the universal wheel 14 can be directly used to push the device. When the device is moved to a suitable position, the universal wheel 14 can be locked to limit its movement.

[0026] A visual box 2 is installed on the top of the base 1. The visual box 2 can be made of transparent glass or plastic, so that the trainees can observe the objects inside the visual box 2 through the visual box 2 from all sides. The inside of the visual box 2 is vertically rotatably connected with a rotating shaft 3. The rotating shaft 3 can be made of metal, such as iron, steel, etc., so as to support the objects thereon and prevent them from being deformed due to load-bearing. A cylinder 4 is fixed in the middle of the outer side of the rotating shaft 3. The cylinder 4 is hollow, so as to reduce its weight and better install it on the rotating shaft 3. A plurality of aircraft instrument bodies 5 are evenly arranged on the outer side of the cylinder 4. A magnifying glass 11 is fixed on the side wall of the visual box 2. Furthermore, an opening and closing door 12 is installed on the outer side of the visual box 2 and at one end away from the magnifying glass 11. Through the setting of the opening and closing door 12, the user can open the opening and closing door 12 and adjust, repair or arrange the devices inside the visual box 2 through the opening and closing door 12.

[0027] The aircraft instrument body 5 can be detachably assembled on the cylinder 4, which can be selected in the following ways:

[0028] The outer side of the cylinder 4 is provided with a plurality of grooves adapted to the aircraft instrument body 5, and magnets are provided between the aircraft instrument body 5 and the grooves on the cylinder 4, so that the aircraft instrument body 5 is adsorbed in the grooves of the cylinder 4. When the aircraft instrument body 5 needs to be disassembled, the aircraft instrument body 5 can be directly disassembled, which is convenient and quick;

[0029] According to the above description, when the user uses the device, the base 1 can be pushed to a suitable position by the universal wheel 14. When the aircraft instrument body 5 needs to be observed, the trainee can directly observe the aircraft instrument body 5 through the visual box 2. When the aircraft instrument body 5 needs to be observed in more detail, the magnifying glass 11 can be used to magnify the image on the aircraft instrument body 5, so that the trainee can observe the aircraft instrument body 5 in more detail.

[0030] A driving mechanism is also installed on the outer side of the rotating shaft 3, and the driving mechanism is used to drive the rotating shaft 3 and the cylinder 4 to rotate.

[0031] See attached Figure 3 The driving mechanism includes a first bevel gear 6 fixed to the outside of the rotating shaft 3, and the outside of the first bevel gear 6 is meshed with a second bevel gear 7. A transmission roller 8 is fixed to the side of the second bevel gear 7 away from the first bevel gear 6. A plurality of support blocks 10 are arranged on the inner side of the visible box 2 and on the outside of the transmission roller 8. Through the arrangement of the support blocks 10, the support blocks 10 can be erected for the transmission roller 8 to avoid the support blocks 10 from being skewed or shaking. The diameter of the second bevel gear 7 is smaller than the diameter of the transmission roller 8, so that when the second bevel gear 7 rotates one circle, the transmission roller 8 rotates less than one circle, so that the cylinder 4 and the aircraft instrument body 5 will rotate slowly, which is convenient for students to observe and avoids too fast rotation and reduced observation effect. The end of the transmission roller 8 away from the second bevel gear 7 extends to the outside of the visible box 2 and is fixed with a rotating wheel 9;

[0032] With this arrangement, when the rotating wheel 9 is rotated, the transmission roller 8 can be driven to rotate by the rotating wheel 9, and then the second bevel gear 7 can be driven to rotate by the transmission roller 8. Through the meshing connection between the second bevel gear 7 and the first bevel gear 6, the second bevel gear 7 can drive the first bevel gear 6 to rotate, so that the first bevel gear 6 can drive the rotating shaft 3, the cylinder 4 and the aircraft instrument body 5 to rotate, and then the different aircraft instrument bodies 5 are rotated to be on the same side as the magnifying glass 11, which is convenient for trainees to observe. In addition, this rotation method attracts observers, has a dynamic effect, and improves its display effect.

[0033] Furthermore, the rotating wheel 9 may be replaced with a motor, so that the output end of the motor is connected to the transmission roller 8, thereby driving the rotating shaft 3 to rotate slowly.

[0034] 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.
