[0028] The utility model discloses a multifunctional modular combined folding pull rod storage box, which has the following beneficial effects: the front box plate, the rear box plate and the bottom plate are respectively composed of three parts, when assembling, the two sides of the front panel 22 are connected with the buckle rings 14 of the two front corner connecting plates 21 through the plug buckles 13 to form a complete front box plate, the two sides of the rear panel 32 are connected with the two rear corner connecting plates 31 through the plug buckles 13 to form a complete rear box plate, and the two sides of the bottom panel 52 are connected with the two bottom side plates 51 through the plug buckles 13 to form a complete bottom plate. The bottom plate is installed at the bottom between the front and rear box plates, one side of the bottom plate is hingedly connected with the front or rear box plate, and the bottom plate can be rotated upward around the hinge shaft to a vertical state. The front and rear folding plates 41 and 42 are hingedly connected to form left and right box plates. The left box plate is installed on the left side between the front and rear box plates, the front side of the left box plate is hingedly connected with the front box plate, and the rear side of the left box plate is hingedly connected with the rear box plate. The right box plate is installed on the right side between the front and rear box plates, the front side of the right box plate is hingedly connected with the front box plate, and the rear side of the right box plate is hingedly connected with the rear box plate. Finally, the front and rear box plates are installed with the casters 11 at the bottom, the telescopic pull rod 12 is installed on the outer wall of the rear box plate, and the box cover 1 is placed on the top of the front and rear box plates to form a pull rod storage box. Since the front box plate, the rear box plate and the bottom plate are respectively composed of three modular structures, different sizes of storage boxes can be formed by replacing the front panel 22 in the front box plate, the rear panel 32 in the rear box plate and the bottom panel 52 in the bottom plate. For example, a wider front box plate can be obtained by replacing the wider front panel 22 (the two front corner connecting plates 21 do not need to be replaced), a wider rear box plate can be obtained by replacing the wider rear panel 32 (the two rear corner connecting plates 31 do not need to be replaced), and a wider bottom plate can be obtained by replacing the wider bottom panel 52 (the two bottom side plates 51 do not need to be replaced). The components are recombined to obtain a storage box (the corresponding box cover 1 also needs to be replaced), which increases the width of the entire storage box and increases the storage capacity of the storage box. Conversely, the width of the entire storage box is reduced. When not in use, the box cover 1 is removed, the bottom plate is rotated upward around the hinge shaft, and the left and right box plates are folded inward around the hinge shaft. At this time, the front and rear box plates are close to each other until they are attached.
