Description

The present invention relates to an improved structure of an automatic turntable, and more particularly to an improved structure of an automatic turntable in which a drive motor can maintain normal rotation for a period when braking a rotating table.

  The automatic turntable structure to which a general drive device is connected is particularly applied to a Chinese-style dining table or other discs that require rotation, and can be rotated automatically, so that it can bring many conveniences in use. However, the conventional automatic rotating board is convenient for cooking, or for other application reasons, the motor is forced to stop the rotation of the rotating table by hand. This causes a phenomenon of braking, which causes the motor to easily overload, causes a short circuit or burnout, and is a drawback of the conventional automatic rotating disk.

  In view of this, the present inventor conducts research and discloses an improved structure of the automatic turntable shown by the present invention.
