Exhibition stand mechanism capable of replacing exhibits without shutdown

Abstract

The invention relates to the technical field of daily life, and discloses an exhibition stand mechanism capable of replacing exhibits without shutdown. The exhibition stand mechanism comprises an exhibition stand shell, and a motor is arranged at the bottom in the exhibition stand shell; a power shaft is connected to the upper surface of the motor in a meshing manner; the middle part of the powershaft is fixedly connected with an auxiliary gear; a main gear is connected to the upper face of the auxiliary gear in an engaged mode; a bearing is arranged in the center of the main gear; the left side of the main gear is fixedly connected with a fixed curved bar; a fastening bolt is arranged at the right end, penetrating through the main gear, of the fixed curved bar; a flange is arranged at the end, away from the main gear, of the fixed curved bar; a central bevel gear is connected to the lower side of the flange; differential gears are engaged with the left side and the right side of thecentral bevel gear; differential shafts are coupled to the centers of the differential gears; and display stand rotating shafts are engaged with the ends, away from the central bevel gear, of the differential shafts. When an exhibit on a certain exhibition stand is replaced, other exhibition stands still keep rotating, and the whole exhibition stand mechanism is not shut down.
