DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 An automatic rotating science display device includes a base 1, a low-speed motor 2 is arranged at the top of the base 1, a display platform 3 is arranged on the output end of the low-speed motor 2, a plurality of rotating shafts 4 are rotatably installed in the display platform 3, the plurality of rotating shafts 4 are evenly distributed in a circle, a tray 5 is arranged on the top of each rotating shaft 4, a gear 6 is arranged on the bottom end of each rotating shaft 4, a first annular groove 7 is opened on the base 1, a second annular groove 8 is opened on the bottom end of the first annular groove 7, a plurality of teeth 9 are arranged on the inner wall of one side of the second annular groove 8, and a plurality of gears 6 are meshed on the teeth 9.

[0022] The exhibits are placed on the tray 5, and the low-speed motor 2 is driven. The output shaft of the low-speed motor 2 drives the display platform 3 to rotate slowly and at a uniform speed. Since the rotating shaft 4 deviates from the center of the display platform 3, the rotating shaft 4 follows the display platform 3 to perform circular motion, and drives the gear 6 to perform circular motion at the same time. When the gear 6 is meshed with the teeth 9 in the second annular groove 8 in sequence, the gear 6 itself rotates, and is connected via the rotating shaft 4, driving the tray 5 to rotate, so that the display platform 3 rotates to display the exhibits in sequence, and at the same time, the tray 5 rotates to change the display angle of the exhibits, thereby improving the display effect and display range.

[0023] Specifically, in the present embodiment, a circular track 10 is provided on the base 1, and a plurality of balls 11 are movably installed in the circular track 10. The plurality of balls 11 are in contact with the bottom end of the display platform 3. The balls 11 provide bottom support for the rotation of the display platform 3 to prevent the display platform 3 from tipping over due to different weights of exhibits. The circular track 10 provides annular movement guides for the plurality of balls 11, thereby preventing the position of the balls 11 from shifting, and making the rotation of the display platform 3 smoother.

[0024] Specifically, in this embodiment, a plurality of through holes 12 are opened on the display platform 3, and a bearing sleeve 13 is sleeved in each through hole 12. The rotating shaft 4 is located in the bearing sleeve 13. The bearing sleeve 13 makes the rotation of the rotating shaft 4 smoother, thereby reducing the sense of frustration when the gear 6 and the teeth 9 are meshed, thereby ensuring the stability of the tray 5 during rotation and preventing vibration.

[0025] Specifically, in this embodiment, each tray 5 is provided with a rubber pad 14, which increases the friction between the exhibit and the tray 5, ensures the stability of the exhibit when placed, and prevents the centrifugal force generated by the rotation and revolution of the tray 5 from throwing the exhibit outward.

[0026] Specifically, in this embodiment, the width of the first annular groove 7 is the same as the diameter of the rotating shaft 4. The rotating shaft 4 is located in the first annular groove 7, which provides the rotating shaft 4 with a movable space for circular motion and a movable space for the rotating shaft itself to rotate.

[0027] Specifically, in this embodiment, the width of the second annular groove 8 is greater than the diameter of the gear 6, and the gear 6 and the teeth 9 are meshed with each other. To ensure smooth rotation of the gear 6, a partial gap is retained between the inner wall of the second annular groove 8 on the side away from the teeth 9 and the outer edge of the gear 6.

[0028] Specifically, in this embodiment, a plurality of universal wheels 15 with built-in brakes are provided on the bottom end of the base 1, so that the display device can be placed stably and be movable.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
