ABSTRACT:
A luggage trolley comprises a baseboard, a pull handle and running wheels. The running wheels are respectively rotatably fixed at two ends of an underside of the baseboard. The pull handle is fixed on the first baseboard periphery and its extending direction and a running direction of the running wheels are in a same plane surface. A foldable board is pivotably connected to a second baseboard periphery. A supporting axis which is parallel to the axle is disposed at an underside of the foldable board. A movable supporting stand is rotationally fixed on the supporting axis. One end of a spiral spring is fixed on the supporting axis and an opposite end thereof is fixed on a hook disposed on the movable supporting stand at a predetermined distance from the supporting axis. One end of the movable supporting stand near the supporting axis is disposed with a stopper which stops further rotation of the foldable board by pressing against the underside of the foldable board when the movable supporting stand rotates around the supporting axis to become perpendicular to a board surface of the foldable board. The present invention is simple to use and transports articles securely.
