The utility model relates to the technical field of paired wheel sets of baby strollers, in particular to a paired wheel set for baby strollers, which comprises a square frame and a partition plate, the inner wall of the square frame is fixedly connected with the outer wall of the partition plate, the front side and the rear side of the partition plate are respectively connected with an installation structure, the outer side of the installation structure is connected with a transverse plate, and the transverse plate is connected with the square frame. The bottom of the square frame is connected with a moving structure, a baby stroller connecting frame is arranged above the square frame, the spring is compressed, when the inclined block moves to the position of the notch, the spring loses pressure and provides resilience force, the square plate moves outwards on the outer wall of the straight rod, then the inclined block is driven to move outwards, the inclined block is inserted into the notch, and paired installation is completed. The transverse plate is pressed towards the inner side to enable the square plate to move towards the inner side on the inner wall of the straight rod, then the inclined block moves towards the inner side to be separated from the notch, and then the square frame is pulled downwards to complete disassembly, so that split type installation is achieved, the replacement cost of the paired wheel set is reduced, and the use limitation is eliminated.
