Description

Technical Field

[0001] The utility model relates to the technical field of stage machinery, in particular to an inclined turntable. Background Art

[0002] At present, in the field of stage machinery, common exhibition platform structures include lifting stages, revolving stages, revolving restaurants, revolving exhibition stand parking equipment countertops, etc. Although the size, dimensions, and detailed structures are slightly different, they usually include an upper countertop parallel to the ground, and the items to be displayed are arranged on the upper countertop. In the prior art, the countertops of exhibition stands are all set parallel to the ground. Such a structure greatly limits the audience's field of vision, especially for the display of large items such as cars, it is difficult to fully present and display the exhibits.

[0003] The utility model patent with application number 201420509158.7 discloses a mechanical friction transmission sloped rotating exhibition stand, which includes a table for placing items to be displayed, a structural support frame and a motor reducer are arranged below the table, and a friction driving wheel for driving the table to rotate is arranged at the power end of the motor reducer. The upper surface and the lower surface of the table are parallel to each other and are both inclined to the ground. The structural support frame located below the table includes a basic steel frame and a plurality of vertical frames with different heights. The basic steel frame is arranged on the ground, and the vertical frame is arranged between the basic steel frame and the table. The bottom of the vertical frame is fixed on the basic steel frame, and the height of the vertical frame gradually changes along the inclination direction of the table. Compared with the structure in the prior art that the table only performs circular motion on the horizontal plane to display items, the overall structure constitutes a sloped rotating exhibition stand, which continuously presents cars or items to the audience in an all-round manner from low to high and from high to low during the rotation process.

[0004] However, the drive of the rotating exhibition stand is set on the bottom side of the table, specifically at the farthest distance between the exhibition stand and the basic steel frame. Since there is no stable connection between the exhibition stand and the vertical frame, the exhibition stand is mainly placed stably on the basic steel frame by the gravity of the exhibition stand and the exhibits, the friction track and the friction driving force, and the friction between the wheels. Therefore, the rotation force acting on the exhibition stand is very likely to cause the exhibition stand to be offset, so the stability is poor. In addition, the center of gravity of the entire structure of the driving principle seriously affects the service life of the drive motor. Utility Model Content
