Novel rotating drive mechanism of locker

The utility model discloses a novel rotating drive mechanism of a locker. The novel rotating drive mechanism comprises a drive motor, an outer chain wheel, small chain wheels, a large chain wheel, an outer chain, an inner chain, an outer rail, an inner rail, rollers, an inner support component, an outer support, a support connecting rod, carrying plates, an upper bent rail component and a lower bent rail component. The novel rotating drive mechanism has the advantages that the bent rail components are made of inner arc rails and outer arc rails, arc raised guides are arranged at the front end and the tail end of each outer arc rail, and in this way, the rollers are conveniently fed in, accordingly ensuring the carrying plates run smoothly; elongated square adjusting clearances are formed in the bent rail components, thus the chains are conveniently mounted; since the bent rail components can be formed at one time by the die, production rate and product precision are high; the inner support component is made of two square rods which rotate around the support connecting rod, so that the fact that the carrying plates fail to stably rotate for bending of the chains during turning is avoided.
