Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 6 The teaching simple rocket principle display model shown in the figure includes a base 2, a support frame 3 is installed on the base 2, an adjustment plate 4 is slidably connected to the support frame 3, a placement plate 41 is connected to one side of the adjustment plate 4, a moving groove 412 is opened on the inner wall of the placement plate 41, a spring 414 is connected inside the moving groove 412, a moving block 413 is connected to one end of the spring 414, and a roller 411 is rotatably connected to the moving block 413;

[0024] A wind-fixing wing 11 is placed on the placement plate 41, and the wind-fixing wing 11 is arranged in a slot on the side of the main tube 1, and a balloon 12 is installed on the top of the main tube 1;

[0025] A slideway 21 is provided on the base 2, and the support frame 3 is slidably arranged in the slideway 21. A handle 22 is rotatably connected to one end of the base 2, and the handle 22 is fixedly connected to a bidirectional threaded rod 23. Both ends of the bidirectional threaded rod 23 pass through the bottom of the support frame 3, and the bidirectional threaded rod 23 is rotatably connected to the base 2. A rubber gasket 24 is provided at the rotation connection between the bidirectional threaded rod 23 and the base 2.

[0026] A tooth block 31 is fixedly arranged in an array on one side of the support frame 3, and the tooth block 31 is inclined;

[0027] A limiting groove 44 is provided inside the adjusting plate 4, and a limiting block 441 is rotatably connected inside the limiting groove 44. A spring piece 443 is provided on one side of the limiting block 441, and the spring piece 443 is fixed inside the limiting groove 44.

[0028] A connecting rod 442 is fixedly provided on the limiting block 441 , one end of the connecting rod 442 is connected to a dial plate 43 , a sliding groove 42 is provided on one side of the adjusting plate 4 , and the connecting rod 442 passes through the sliding groove 42 .

[0029] In this solution, when the model is in use, the staff adjusts the distance between the support frames 3 according to the rocket models of different design sizes, drives the bidirectional threaded rod 23 to rotate by rotating the handle 22, and utilizes the spiral connection between the bidirectional threaded rod 23 and the support frame 3, so that the support frame 3 moves along the slide 21 under the rotation of the bidirectional threaded rod 23, so that the distance between the two support frames 3 can be adjusted, and the rubber gasket 24 provided at the connection between the bidirectional threaded rod 23 and the base 2 can increase the rotational friction between the bidirectional threaded rod 23 and the base 2, thereby preventing the bidirectional threaded rod 23 from loosening and deflecting;

[0030] When understanding the influence of the position and shape of the fixed wind wing 11 on the flight stability of the rocket, it is necessary to adjust the height of the placement plate 41 to adapt to the different positions of the fixed wind wing 11. The bottom of the rocket model always maintains the same distance from the base 2. By controlling the variables, other factors are avoided from affecting the students' observation, so that students can more intuitively understand the influence of the fixed wind wing 11 on the flight stability of the rocket. When adjusting the height of the placement plate 41, under normal conditions, the spring piece 443 inside the adjustment plate 4 squeezes the limit block 441, so that the limit block 441 is close to the top inner wall of the limit groove 44. At the same time, one end of the limit block 441 protrudes out of the limit groove 44 and is plugged into the tooth block 31, so that the tooth block 31 and the limit block 441 are used to limit the adjustment plate 4. The limit block 441 is moved along the bottom of the tooth block 31 to squeeze the spring piece 443, so that the limit block 441 rotates back into the limit slot 44, thereby driving the placement plate 41 to move upward. When the height needs to be lowered, the staff needs to toggle the dial plate 43 along the slide slot 42, and control the limit block 441 to rotate through the connecting rod 442 connected to the dial plate 43, and squeeze the spring piece 443, so that the limit block 441 enters the limit slot 44, avoiding the limit block 441 from being inserted into the tooth block 31 during the movement, which is convenient for the staff to lower the height of the placement plate 41.

[0031] When teaching and researching the flight direction of a rocket model, it is necessary to adjust the bending condition of the corrugated connecting tube at the bottom of the rocket model, so that the bottom of the rocket model is not easy to place, resulting in the main tube 1 of the rocket model being easy to tilt during launch. Therefore, it is necessary to use a placement plate 41 to control the rocket model to maintain a normal launching state. When placing the rocket model, the fixed wind wings 11 on both sides of the rocket model are placed on the placement plates 41 on both sides of the rocket model, and the moving block 413 is pushed by a spring 414. The fixed wind wings 11 of the rocket model are clamped and fixed by the roller 411 in the moving block 413, so that the rocket model is in a normal launching state to avoid the rocket model from tilting during launch. The roller 411 is rotatably connected to the moving block 413, which can reduce the friction on the fixed wind wings 11, thereby facilitating the rocket model to fly using the recoil principle.
