[0001] This utility model relates to the field of professional teaching equipment, and in particular to a teaching tool that can simulate the practice of setting a ruler. Background Technology

[0002] In the training scenarios of machine gun calibration and manual sight setting for a certain type of armored vehicle, the drum sight, as a key device for setting the reticle of the sight circle, plays an indispensable role in weapon calibration and actual firing.

[0003] However, many difficulties exist in the teaching and training process. On the one hand, trainees often have questions when learning how to use and operate the drum-type sight. However, due to the relatively narrow interior space of armored vehicles, it is not convenient for instructors to conduct group demonstrations and detailed explanations, making it difficult for trainees to thoroughly understand the working mechanism and key points of operation of the drum-type sight. This hinders the development of trainees' subsequent practical application capabilities.

[0004] On the other hand, hands-on training has certain limitations and cannot fully meet teaching needs. Relying solely on hands-on equipment for operation and usage explanations during training is not only costly but also prevents teaching activities from being conducted anytime and anywhere, limiting the flexibility and relevance of teaching. Furthermore, frequent use of hands-on equipment may lead to increased equipment wear and tear, affecting the normal lifespan of the equipment.

[0005] Therefore, it is necessary to provide a teaching aid that can simulate the practice of setting a ruler to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a teaching aid that can simulate the practice of setting a dial indicator, solving the problems of narrow vehicle interior space, difficulty for instructors to collectively demonstrate and explain the drum dial indicator in detail, and trainees' inability to thoroughly understand its principles and operating points, thus hindering the cultivation of practical application ability; high cost, limited flexibility and relevance of practical training, and frequent use increasing equipment wear and tear, affecting the service life of equipment.

[0007] To solve the above-mentioned technical problems, this utility model provides a teaching aid that can simulate the practice of setting a dial indicator, comprising:

[0042] First Embodiment

[0043] Please refer to Figures 1, 2, 3, 4, 5, 6, 7, and 8. Figure 1 is a structural schematic diagram of the first embodiment of a teaching aid for simulating the setting of a dial indicator, provided by this utility model; Figure 2 is an enlarged schematic diagram of part A shown in Figure 1; Figure 3 is a three-dimensional structural schematic diagram of the internal structure of the dial indicator teaching aid shown in Figure 1; Figure 4 is an enlarged schematic diagram of part B shown in Figure 3; Figure 5 is a structural schematic diagram of the internal structure of the dial indicator teaching aid shown in Figure 1; Figure 6 is a three-dimensional structural schematic diagram of the external structure of the dial indicator teaching aid shown in Figure 1; Figure 7 is an enlarged schematic diagram of part C shown in Figure 6; and Figure 8 is an enlarged schematic diagram of part D shown in Figure 6. A teaching aid for simulating the setting of a dial indicator includes:

[0044] Base 1, housing 2, rotating assembly 3, indicator block 4, rotating assembly 9, rotating rod 8, and dial 10;

[0045] The housing 2 is mounted on the surface of the base 1, and the rotating assembly 3 is disposed inside the housing 2. The rotating assembly 3 includes two drive wheels 31 and a belt 32, with the belt 32 disposed between the two drive wheels 31.

[0046] The indicator block 4 is connected to the surface of the belt 32;

[0047] The rotating component 9 is disposed on the surface of the housing 2;

[0048] The rotating rod 8 is disposed between one of the drive wheels 31 and the housing 2;

[0049] The dial 10 is disposed on one side of the rotating assembly 9.

[0050] Another drive wheel 31 is provided with a rotating rod 7 between it and the housing 2, and a transparent cover 5 is installed on one side of the housing 1.

[0051] A rectangular through groove 6 is provided on one side of the surface of the housing 2.

[0052] The rotating assembly 9 includes a circular shell 91, a gear ring 92, a first gear 93, and two second gears 94. The gear ring 92 is installed inside the circular shell 91. The first gear 93 is located at the center inside the gear ring 92. The two second gears 94 are respectively located on both sides of the first gear 93. An arc-shaped through groove 11 is formed on the surface of the circular shell 91.

[0053] Rotating rod 8 and rotating rod 7 are rotatably connected to one side of the inner wall of housing 2 via rotating shafts. The two drive wheels 31 can straighten the belt 32 by pulling. Matching toothed blocks are installed on both drive wheels 31 and belt 32.

[0054] In use, when adjusting the indicator block 4 up and down, rotating the rotating rod 8 drives the first gear 93 to rotate. When the rotating rod 8 rotates, it drives one of the drive wheels 31 to rotate. When one of the drive wheels 31 rotates, it drives the other drive wheel 31 to rotate via the belt 32. When the belt 32 rotates, it drives the indicator block 4 on the surface to adjust its up and down position on the ruler 5. At the same time, when the first gear 93 rotates, it drives the two second gears 94 to rotate. When the two second gears 94 rotate, they drive the scale 10 on one side to rotate. When the scale 10 rotates, the information can be viewed through the arc-shaped through groove 11 on the surface of the circular shell 91.

[0055] Rotating the elevation and lowering gun's rotating lever 8 counterclockwise moves the circle downwards and sets the sights; rotating the elevation and lowering gun's handwheel clockwise moves the circle's divisions upwards; the triangular divisions on the acrylic plate simulate the scene in the aiming field of view.

[0056] When using the teaching aid, take it out of the storage box, operate the height adjustment cannon handwheel or external dial according to the teaching content, and explain it. After use, zero the scale and dial, and put the teaching aid back into the storage box.

[0057] When using it, avoid dropping it from a height or bumping it, and avoid rotating the gun adjustment handwheel too forcefully to reach the upper or lower limit.

[0058] Wipe the knob before and after use. If the knob is stuck, remove the back cover and apply oil for lubrication.
