The invention provides a virtual product rotary observation device for industrial design. The virtual product rotary observation device comprises an observation assembly, supporting legs, a dust collection assembly, an electric control cabinet and a PLC. According to the device, the observation assembly is arranged, a PLC controls a driving motor to be powered on and run, the driving motor drives a rotating rod to rotate through a driving belt wheel and drives a first placement assembly and a second placement assembly to rotate, and therefore viewers can conveniently watch virtual products in all directions, when the first placement assembly rotates, the slide way ring plays a role in guiding and limiting the first placement assembly, so that the operation stability of the observation device is improved, the phenomenon that the first placement assembly and the second placement assembly shake during rotation is avoided, and the phenomenon that a virtual product flies out is prevented; through the arrangement of the first placement assembly and the second placement assembly, the lower end of the virtual product is clamped in the placement groove, the strong magnet fixes the virtual product through magnetic force, the strong magnet further fixes the virtual product, and the placement stability of the virtual product is improved.
