The utility model relates to the technical field of engine transmission structures, in particular to an anti-loosening engine belt pulley connecting structure. According to the technical scheme, the device comprises a clamping ring plate, a device groove is formed in the clamping ring plate, three sets of movable grooves in a circumferential array are formed in the outer side of the clamping ring plate, three sets of abutting plates are arranged in the device groove, connecting rods are fixedly connected to the interiors of the three sets of abutting plates, and the connecting rods are rotationally connected with the device groove; reset mechanisms are arranged on the peripheries of the three sets of abutting plates. The abutting plate is driven by centrifugal force to lock the belt pulley in a self-adaptive mode, the clamping ring plate and the abutting plate form a centrifugal response assembly, the axial pressing force is automatically enhanced along with increase of the rotating speed of the main shaft, and the rotating speed self-adaptive wedge-shaped clamping effect is formed; the reset mechanism ensures lossless decoupling in a shutdown state through an energy storage release circulation function, and the structure converts centrifugal potential energy into a dynamic self-locking load, so that the automation degree of the device is improved.
