[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0021] With reference to Figs. 1 to 3 The utility model provides a magic pill tumbling demonstration popular science teaching aid, including tumbling piece 1 and adjustable support 2, tumbling piece 1 has the cavity 11 inside, the steel ball 12 is provided in the cavity 11, adjustable support 2 includes bottom plate 3, adjustable support structure 4 and moving rail 5, bottom plate 3 has first end 31 and second end 32, first end 31 is provided with first mounting portion 311, adjustable support structure 4 is rotatably connected in first mounting portion 311, one end of moving rail 5 is rotatably connected in adjustable support structure 4, the other end is rotatably connected in second end 32, adjustable support structure 4 is adjusted to make moving rail 5 gradually tilt / flatten.

[0022] Understandably, tumbling piece 1 is the cylinder of hemispherical two ends, its inside is hollow, and the steel ball 12 is placed inside, adjustable support structure 4 lifts one end of moving rail 5 and forms an inclined plane, when tumbling piece 1 is placed in the higher end of moving rail 5, tumbling piece 1 will tumble all the way down by the way similar to "somersault" instead of directly rolling to the bottom of moving rail 5, its principle is because the steel ball 12 in tumbling piece 1 makes the gravity center of tumbling piece 1 move back and forth, tumbling piece 1 rotates around the gravity center, so tumbling piece 1 will move like somersault, in this process, when tumbling piece 1 tumbles, the gravity center constantly moves to the front end of tumbling piece 1, the gravitational potential energy of steel ball 12 constantly converts into the kinetic energy of tumbling piece 1, which visually demonstrates the energy conversion process to the viewer, and is full of interest.

[0023] Adjustable support structure 4 is composed of two support arms that can rotate with each other, the two support arms form a bent included angle, adjusting the size of the included angle can adjust the inclination degree of moving rail 5, in addition, adjustable support structure 4 can also be a motorized telescopic rod, a hydraulic device and the like, which can all adjust the inclination degree of moving rail 5, and can also support moving rail 5 after adjustment, so that the adjustment process of moving rail 5 is convenient and fast, and there is no need to hold moving rail 5 to maintain the stability of moving rail 5.

[0024] With reference to Figs. 1 to 2 In an embodiment of the present application, adjustable support structure 4 includes first support arm 41 and second support arm 42, and both have mounting end 43 and connecting end 44, the connecting ends 44 of the two are rotatably connected, the mounting end 43 of first support arm 41 is rotatably connected to first mounting portion 311, and the mounting end 43 of second support arm 42 is rotatably connected to moving rail 5.

[0025] It can be understood that the connecting end 44 of the first support arm 41 and the second support arm 42 are rotatably connected together to form an adjustable included angle, and the inclination of the moving rail 5 can be adjusted by adjusting the size of the included angle. Compared with the structure of the electric telescopic rod, the hydraulic device and the like, the above structure is more simple and practical, has low manufacturing difficulty, low production cost, and is more suitable for large-scale production and application.

[0026] With reference to Figs. 1 to 2 In an embodiment of the present application, the first end 31 of the bottom plate 3 is provided with two fixed plates 312, and the two fixed plates 312 form a mounting groove 313 therebetween, and the mounting end 43 of the first support arm 41 is rotatably connected to the mounting groove 313.

[0027] It can be understood that in the present example, the two parallel fixed plates 312 form a first mounting portion 311, and the mounting end 43 of the first support arm 41 is inserted into the mounting groove 313 between the fixed plates 312 and connected by buckling, hole column, threaded connection or the like. Through the above arrangement, on the one hand, it plays a protective and limiting role for the first support arm 41, and the mounting end 43 is covered and protected, and it can also prevent displacement of the first support arm 41 to make the moving rail 5 unstable, thereby affecting the tumbling effect of the tumbling piece 1; on the other hand, it has a simple and practical structure, is easy to produce and manufacture, and the connection is relatively firm and not easy to loosen.

[0028] With reference to Figs. 1 to 2 In an embodiment of the present application, the bottom of the moving rail 5 is provided with a second mounting portion 51, and the mounting end 43 of the second support arm 42 is rotatably connected to the second mounting portion 51.

[0029] It can be understood that the second mounting portion 51 is a downwardly protruding plate structure, and a connecting hole, a threaded hole, a clamping groove or a buckle and the like structure can also be provided in this part, and the mounting end 43 of the second support arm 42 is connected to this part, which can realize free rotation of the moving rail 5 and support the moving rail 5, and the connection is firm and easy to disassemble and assemble.

[0030] With reference to Figs. 1 to 2 In an embodiment of the present application, the second end 32 of the bottom plate 3 is provided with a connecting piece portion 321, and the edge of the connecting piece portion 321 is provided with a stop plate 322.

[0031] It can be understood that the connecting piece portion 321 can facilitate the recycling of the tumbling piece 1 rolling down. Since the tumbling piece 1 rolls from the first end 31 to the second end 32, it carries a large amount of kinetic energy when it rolls to the second end 32. The connecting piece portion 321 can buffer the tumbling piece 1, and the edge of the connecting piece portion 321 is provided with the stop plate 322 to intercept the tumbling piece 1 and prevent it from rolling around and being difficult to recycle.

[0032] With reference toFigs. 1 to 2 In an embodiment of the present application, the two side edges of the moving track 5 are provided with protective plates 52.

[0033] It can be understood that, since the length of the moving track 5 can be long, the rolling piece 1 can deviate from the moving track 5 when rolling, and the protective plates 52 are provided to prevent the rolling piece 1 from rolling out of the moving track 5, thereby affecting the use process, and even causing damage to the rolling piece 1. When the rolling piece 1 contacts the protective plate 52, it will continue to roll along the moving track 5 under the blocking action of the protective plate 52.

[0034] The technical scheme of the present application comprises the following steps: the adjustable support structure 4 composed of the first support arm 41 and the second support arm 42 is arranged on the adjustable support 2, and the inclination of the moving track 5 can be adjusted relatively conveniently by adjusting the adjustable support structure 4, so that the rolling piece 1 achieves the best rolling effect, and the adjustable support structure 4 can keep the moving track 5 stable, so that the inclination of the moving track 5 does not need to be maintained by external force during use, which saves time and effort, and also makes the rolling effect of the rolling piece 1 better.
