[0038] Example 1:

[0039] Please refer to Figure 1 - Figure 4 , a particle collision experimental device, comprising:

[0040] Liquid container 1, which is a transparent sealed container;

[0041] The falling adjustment frame 2 is arranged on the outside of the liquid container 1 and is used for supporting, positioning and dropping the particles; the falling adjustment frame 2 includes a stable base frame 4, the upper end of one side of the stable base frame 4 is vertically fixedly connected to a fixed vertical rod 5, the top of the fixed vertical rod 5 is horizontally fixedly connected to a fixed cross bar 6, the lower end of the fixed cross bar 6 and the side away from the fixed vertical rod 5 is laterally movable with a movable longitudinal rod 7, one side of the movable longitudinal rod 7 is vertically movable with a movable vertical rod 8, and the lower end of the movable vertical rod 8 extends to the inside of the liquid container 1; wherein, two positioning pieces 9 are provided at one end of the stable base frame 4, and the two positioning pieces 9 are respectively located at the positions on both sides of the liquid container 1.

[0042] It can be seen that the support of the fixed vertical rod 5 and the structure above the fixed vertical rod 5 can be achieved through the stable base frame 4. The movable longitudinal rod 7 is connected to the fixed cross rod 6, so that the horizontal position of the particle can be adjusted by sliding the movable longitudinal rod 7. The vertical position of the movable vertical rod 8 and the movable longitudinal rod 7 slide, so that the vertical position of the particle can be adjusted by sliding the movable vertical rod 8. Through the two-way position adjustment, the experimental requirements of the falling position of the particle can be met.

[0043] The angle adjustment frame 3 is arranged inside the liquid container 1 and is used for bearing and angle adjustment of the collision plate; the angle adjustment frame 3 includes a detachable vertical rod 10, and the number of detachable vertical rods 10 is two. The two detachable vertical rods 10 are arranged vertically and parallel.

The placing plate 13 is rotatably connected to the supporting arm 12, and a placing frame 14 is placed on the top of the placing plate 13.

[0044] It can be seen that through the rotation connection between the placement plate 13 and the support arm 12, the placement plate 13 can be adjusted in angle according to the experimental requirements, and the positioning and placement of the experimental plate is achieved through the placement frame 14, and the stabilizing rod 11 and the support arm 12 are detachably fixedly connected to the detachable vertical rod 10, so that the installation, disassembly, maintenance and cleaning of the support arm 12 and the placement plate 13 are relatively convenient.

[0045] To facilitate the study of particle collision trajectories, a simple device was designed. The main body is a transparent container that can be filled with water. An external drop adjustment frame 2 controls the height and position of the ball release. Inside is a removable angle adjustment frame 3, whose center can be replaced with different collision material plates. This device allows the ball to collide at different heights, angles, and in the presence or absence of water to test its collision trajectory.

The placement frame 14 is placed above the L-shaped support plate 15, and the lower end of the L-shaped support plate 15 is fixedly connected to the adjustment plate 17. The adjustment plate 17 is rotatably connected to the support arm 12 on the same side through the rotating shaft 18. An angle slot 19 is provided on the adjustment plate 17, and a limit buckle that cooperates with the angle slot 19 is provided on the support arm 12.

[0051] Furthermore, the number of the angle slots 19 is five, and the five angle slots 19 are respectively set to positions of 0°, 15°, 30°, 45°, and 60°.

When the placement plate 13 rotates, it rotates around the rotating shaft 18 as the axis, and the limit buckle on the support arm 12 cooperates with the angle slot 19 at the corresponding position, so as to achieve the limiting effect of the adjusted placement plate 13.
