The drawings show typical embodiments of the utility model. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.
[0021] Figure 1 As shown is the structure schematic view of the falling ball experiment device for sharing different material testing balls provided by an embodiment of the utility model.

Among them, the fixed bottom plate 100 provides a support base for the whole device, ensuring the stable installation of all other components; the positioning support assembly 200 is fixed on the top surface of the bottom plate, vertically supports the falling ball adsorption assembly, ensures that the falling ball adsorption assembly is in a preset position during the experiment process, and can accurately control the falling of the testing ball; the falling ball adsorption assembly 300 fixes the testing ball through adsorption force, adsorbs balls of different materials and sizes to a preset position, and prepares for the free fall experiment; the air suction control assembly 400 can accurately control the release of the balls adsorbed on the falling ball adsorption assembly at the appropriate time, starting the free fall experiment.
[0022] In this embodiment, since the air suction mode is adopted to adsorb the test ball, the device can adapt to balls of different materials (such as metal, plastic, rubber, etc.) and different sizes. This makes the experimental device not only limited to a certain type of ball, but also can conduct more extensive free fall experiments to meet different test requirements. At the same time, different materials or sizes of balls can be easily replaced on the same set of equipment for testing, without the need for special equipment or multiple tools, facilitating flexible adjustment of the experiment. The design of the positioning support assembly ensures that the ball adsorption assembly can remain in a fixed position throughout the experiment. This allows the release point and falling height of the ball to be accurately controlled each time the test is conducted, avoiding fluctuations in the results caused by equipment errors. By controlling adsorption and release through the air suction control assembly, the experimenter does not need to manually intervene, reducing human error and improving the accuracy of the experiment.
[0023] Specifically, in an embodiment of the utility model, the positioning support assembly 200 includes a positioning support body 210 and a plurality of reverse supports 220, the lower end of the positioning support body 210 is fixed on the top surface of the fixed bottom plate 100 through the plurality of reverse supports 220, and the reverse support is designed reversely through a mechanical structure, so that the positioning support body 210 can be kept in a fixed position with high stability. In this embodiment, the positioning support body 210 is a cuboid to provide sufficient stability and facilitate docking and fixing with other components; four side surfaces are respectively provided with clamping grooves 2101, which can further fix or install other components, facilitate adjusting the position or replacing the assembly in the experimental device, and can enhance the connection stability between the positioning support body and other components. Further, the positioning support body is made of profile steel, which not only ensures the firmness of the support body, but also makes the entire device have high carrying capacity to adapt to different experimental loads.
[0024] In this embodiment, the reverse support is used to fix the positioning support body, so that the support body will not be displaced due to external force or vibration during use. This design helps to ensure the height accuracy and stability in the experiment, avoiding errors caused by loose support body of the equipment. The design of the four clamping grooves not only fixes the support body, but also provides better flexibility and adjustment space for the docking between components. This makes the positioning support body more stably connected with other components and less susceptible to external interference. The combination of the cuboid profile steel and the reverse support not only enhances the rigidity of the positioning support body, but also improves the anti-deformation ability of the overall structure, so that the influence of external forces (such as heavy objects, vibration, etc.) on the support body during the experiment is minimized.

Through this double connection mode, the stability of the reverse support is greatly improved. At the same time, the structural design of the reverse support makes the installation and disassembly of the components very flexible.
[0026] In this embodiment, by adopting the screw connection of the threaded hole and the reverse support, combined with the design of the spring nut and the fixing bottom plate, the structure of the entire equipment is more firm, stable and reliable. Such design not only improves the shock resistance and carrying capacity of the device, but also makes the assembly, adjustment and maintenance of the components more convenient, ensuring high precision and high stability during the experiment.
