[0045] The usage of the multifunctional legal science popularization equipment is as follows:

[0046] 1) When no one is interacting, the driving motor 81 is started to make the promotional poster 5 roll inside the display box 2, and people can directly view the content on the promotional poster 5 by the rolling of the promotional poster 5;

[0047] 2) During the interaction, the experiencer directly sits on the spinning bike 93. When the experiencer steps on the spinning bike 93 to rotate, the rotating shaft of the spinning bike 93 drives the third bevel gear 97 to rotate through the second bevel gear 96, the first bevel gear 95 and the universal coupling 94. Then the third bevel gear 97 drives the built-in bevel gear 813 to rotate through the fourth bevel gear 98 and the inner rod 812.

At this time, the driving gear 88 drives the passive gear 89 and the roller 4 to rotate, and the promotional poster 5 rolls inside the display box 2. People can directly view the content on the promotional poster 5 by rolling the promotional poster 5;

[0048] 3) After the promotional poster 5 has rolled around for a circle, the prize in the filling slot 101 will be pushed out and finally fall into the taking slot 108 through the discharging slot 102. Then the interactor can directly take the prize through the taking slot 108. By setting a goal, the user has a specific direction to pursue, so that the user can have something to look forward to during the interaction and gain a sense of accomplishment, while achieving better legal science popularization;

[0049] 4) When the device is installed outdoors, when it rains, rainwater will enter the water storage tank 172 through the water collection tank 16, and float the foam float 175, and trigger the second touch switch 176 through the lever principle to start the servo motor 12, so that the protective plate 14 can rotate, so that passers-by can take shelter from the rain through legal science publicity, thereby improving the functionality of the legal science publicity device.

[0050] In summary, when no one is interacting with the multifunctional legal science popularization device, the driving motor 81 is started, and the driving motor 81 drives the rotating drum 84, the square rod 86 and the square hole rotating rod 87 to rotate through the driving bevel gear 82 and the driven bevel gear 83. The rotation of the square hole rotating rod 87 drives the rotating roller 4 to rotate through the driving gear 88 and the driven gear 89, so that the propaganda poster 5 rolls inside the display box 2, and people can directly view the content on the propaganda poster 5 by the rolling of the propaganda poster 5;

[0051] During the interaction, the experiencer sits directly on the spinning bike 93. At this time, due to the gravity of the experiencer, the spinning bike 93 drives the skateboard 992 to slide downward, and triggers the first touch switch 995 to start. At this time, after the promotional poster 5 rotates for one circle, the driving motor 81 is turned off, and the electric telescopic rod 810 drives the rotating drum 84 to slide downward. At this time, the rotating drum 84 drives the transition bevel gear 85 and the driven bevel gear 83 to slide downward. At the same time, the driven bevel gear 83 is not connected to the driving bevel gear 82, and the surface of the transition bevel gear 85 is meshed with the built-in bevel gear 813. When the experiencer steps on the spinning bike 93 to rotate, The rotating shaft of the spinning bike 93 drives the third bevel gear 97 to rotate through the second bevel gear 96, the first bevel gear 95 and the universal joint 94, and then the third bevel gear 97 drives the built-in bevel gear 813 to rotate through the fourth bevel gear 98 and the inner rod 812, and the built-in bevel gear 813 drives the rotating drum 84, the square rod 86, the square hole rotating rod 87 and the driving gear 88 to rotate through the transition bevel gear 85. At this time, the driving gear 88 drives the passive gear 89 and the roller 4 to rotate, and the promotional poster 5 rolls inside the display box 2. People can directly view the content on the promotional poster 5 by rolling the promotional poster 5;

[0052] After the poster 5 has rolled for one circle, the stepper motor 106 will start and drive the threaded rod 107 to rotate. At this time, the driving plate 105 drives the top block 104 to slide upward for a certain distance and pushes out the prize inside the filling slot 101, and finally drops it into the taking slot 108 through the discharging slot 102. Then the interactor directly takes the prize through the taking slot 108. By setting a goal, the user has a specific direction to pursue, so that the user can have expectations in the process of interaction and can gain a sense of accomplishment, while achieving better legal science popularization;

[0053] By installing the control device 17, when the device is installed outdoors, when it rains, rainwater will enter the water storage tank 172 through the sump 16, and float the foam float 175, and trigger the second touch switch 176 through the lever principle to start the servo motor 12, so that the protective plate 14 can be rotated and perpendicular to the display box 2, so that passers-by can take shelter from the rain through the legal science publicity, thereby improving the functionality of the legal science publicity device.
