Description

Technical Field

[0001] The utility model relates to the technical field of photographic turntables, and specifically relates to a photographic turntable. Background Art

[0002] A photographic turntable is a device used for photographic work. It is usually composed of one or more supporting platforms and one or more rotating devices. Its main function is to support and rotate the subject to obtain the best shooting angle and lighting effect. The application of photographic turntable is very wide. It is suitable for various types of photographic work. With the continuous advancement of photographic technology and industrial manufacturing technology, photographic turntables are also constantly developing and evolving to provide photographers with better shooting experience and effects.

[0003] However, the load capacity of the turntable needs to be considered during use. Failure to support and rotate smoothly will cause vibration and deviation of the turntable, which will affect the positioning and stability of the subject. This may cause the image of the subject to be blurred or unclear, thus affecting the final shooting effect. In addition, long-term unstable use will cause wear of bearings, gears and other components, and may even cause safety problems. The turntable needs to support and rotate the subject in different directions to obtain the best shooting effect. If rotation in different directions cannot be achieved, the photographer needs to adjust the angle and position of the turntable multiple times. Therefore, we propose a photographic turntable to ensure its long-term stable performance. Utility Model Content

[0006] Preferably, it also includes a bracket structure, which is arranged on the outer side of the pin gear ring and on the other side away from the driving motor, and the side wall of the bracket structure is gap-matched with the pin gear ring.

[0007] Preferably, the support structure includes a base, the side wall of the base is fixedly connected to the outer support wheel, the upper surface of the base is fixedly connected to an inner rod, the outer wall of the inner rod is sleeved with an outer rod, the top of the outer rod is fixedly connected to a screw hole platform, the lower surface of the screw hole platform is fixedly connected to a first screw hole rod, the inner cavity of the first screw hole rod is threadedly connected to a bidirectional screw, the other side of the bidirectional screw is threadedly connected to a second screw hole rod, and the bottom end of the second screw hole rod is fixedly connected to the upper surface of the base.

[0008] Preferably, the upper surface of the screw hole platform is provided with screw holes in a ring shape.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: when in use, the evenly distributed support wheels and multi-point support make the overall structure more stable, while reducing the load weight of a single point. The smooth support and rotation prevent the vibration and deviation of the turntable, and avoid affecting the positioning and stability of the photographed object. The turntable needs to support and rotate the photographed object at different angles and directions to obtain the best shooting effect, and the drive motor is symmetrically arranged to achieve angle control of the turntable. It adopts dual drive and single engagement. When one unit has a problem, the other unit can be quickly replaced, realizing 360° photography in a specific direction of the turntable and rotation in different directions. The photographer does not need to adjust the angle of the turntable multiple times. BRIEF DESCRIPTION OF THE DRAWINGS
