The invention discloses a locked power strip structure comprising a base, a revolving disc rotationally mounted on the base, a main body fixedly mounted on the revolving disc, and connectors in locking connection with the main body. Multiple engaging seats are arranged on the left end surface of the main body. A tight insertion cavity is arranged in the left end surface of each engaging seat. A first power connector is fixedly disposed on the right inner wall of each tight insertion cavity. First sliding chambers are symmetrically disposed in the upper and lower inner walls of the tight insertion cavity. An oblique locking block is slidably mounted in each first sliding chamber. Second sliding chambers are disposed on the right inner walls of the first sliding chambers. First sliding blocks are slidably mounted in the second sliding chambers. Pushing springs are press-fit mounted in the second sliding chambers on the opposite sides of the first sliding blocks on the upper and lower sides.
