The invention discloses a wheel leg structure capable of being folded and unfolded, and relates to the field of wheel carrier structures. According to the technical scheme, the wheel leg structure comprises a main body, guide rails, sliding blocks, wheel rods and rolling wheels; the guide rail is vertically arranged on the main body, the sliding block is in sliding fit with the guide rail, a clamping mechanism is arranged between the guide rail and the sliding block, and the clamping mechanism enables the sliding block to be fixed to the upper section or the lower section of the guide rail; the upper ends of the two wheel rods are located on the two sides of the guide rail respectively, the lower ends of the two wheel rods are obliquely arranged in the opposite directions, the wheel rods are in sliding fit relative to the main body, the upper ends of the wheel rods are connected with the sliding blocks through connecting rods, and rolling wheels are arranged at the lower ends of the wheel rods. The retraction or extension of the wheel rod relative to the main body can be well realized, the state of the wheel rod can be locked and unlocked, and the wheel rod is kept in the retraction or extension state. A user can select to use according to actual needs.
