(16) As shown in FIG. 1 to FIG. 14, the invention provides a storage box 1, including a rectangular bottom plate 10, a side plate 20, a reinforcing ring 30 and a top lid 40. The four side plates 20 are arranged on front, rear, left and right edges of the bottom plate 10, and side edges of every two adjacent side plates 20 are hinged with each other, so that the four side plates 20 and the bottom plate 10 jointly form an accommodating chamber 50 with a top opening. The side plates 20 on left and right sides are capable of being folded front and rear or unfolded front and rear to form a vertical flat surface. The side plates on the left and right sides are folded to drive the side plates 20 on front and rear sides close to each other, and unfolded to drive the side plates 20 on the front and rear sides away from each other. A rear side of the bottom plate 10 is hinged to the side plate 20 on the rear side, so that the bottom plate 10 is flippable up and down along hinges. The bottom plate is capable of opening a bottom of the accommodating chamber 50 when being flipped up, and capable of blocking the bottom of the accommodating chamber 50 and abutting against the side plate 20 on the front side when being flipped down; when the bottom plate 10 is flipped up and the side plates 20 on the left and right sides drive the side plates 20 on the front and rear sides close to each other, the storage box 1 is in a folded state. When the side plates 20 on the left and right sides are unfolded to drive the side plates 20 on the front and rear sides away from each other and the bottom plate 10 is flipped down to block the bottom of the accommodating chamber 50 and abut against the side plate 20 on the front side, the four side plates 20 and the bottom plate 10 jointly form the accommodating chamber 50 with the top opening, the storage box 1 is in an unfolded state, and in this case, the four side plates 20 and the bottom plate 10 jointly form the accommodating chamber 50 with the top opening; a bottom of the annular hard reinforcing ring 30 is recessed upward to form an insertion slot 31, and when the storage box 1 is in the unfolded state, tops of the four side plates 20 are insertable into the insertion slot 31, so that the reinforcing ring 30 limits the side plates 20 on the left and right sides from being folded front and rear. The top lid 40 covers a top of the reinforcing ring 30, thereby blocking the top opening of the accommodating chamber 50. Specifically, the rear side of the bottom plate 10 is hinged to a bottom of the side plate 20 on the rear side. Specifically, the reinforcing ring is made of a hard material, such as hard plastic.

(17) In the invention, the storage box 1 further includes the annular hard reinforcing ring 30, the bottom of the reinforcing ring 30 is recessed upward to form the insertion slot 31, and when the storage box 1 is in the unfolded state, the tops of the side plates 20 on the left and right sides are also in the unfolded state, and in this case, the tops of the four side plates 20 are all inserted into the insertion slot 31 such that the reinforcing ring 30 is utilized to limit the side plates 20 on the left and right sides from being folded front and rear, thereby improving the firmness of the storage box 1 in the unfolded state. Moreover, the tops of the four side plates 20 are all inserted into the reinforcing ring 30, so that the reinforcing ring 30 provides supporting power for the four side walls, which makes the storage box 1 in the unfolded state more firm. In addition, when the storage box 1 is in the unfolded state, the top opening is more stable, and the reinforcing ring 30 makes the four side plates 20 less likely to wobble in the insertion slot 31, which makes the accommodating chamber 50 less likely to deform, thereby improving the stability.

(18) Further, the bottom plate 10 is provided with a hand lifting portion 11, so that the bottom plate 10 is flippable up by pulling the hand lifting portion 11.

(19) Preferably, the hand lifting portion 11 is a circular hole 111 provided at a front side of the bottom plate 10, so that a human finger is extendable into the circular hole 111 to pull the front side of the bottom plate 10 up, which facilitates folding of the storage box 1.

(20) Further, the top lid 40 is hinged to the reinforcing ring 30, and the top lid 40 is flippable up along the hinges to open the top opening of the accommodating chamber 50 or flippable down to cover the top opening of the accommodating chamber 50.

(21) Preferably, the top lid 40 is hinged to the reinforcing ring 30 through connecting members 32, there are two connecting members 32 hinged to an inner side wall of the reinforcing ring 30 on a same side, one end of each of the connecting members 32 is hinged to the reinforcing ring 30, and the other end forms a snap fit with the top lid 40. Specifically, the connecting member 32 is J-shaped. The end of the connecting member with a lower level is hinged to an inner side of the reinforcing ring 30, and the end with a higher level faces up and forms a snap fit with the bottom of the top lid 40. The higher end rotates around the lower end, so that the top lid 40 opens the top of the accommodating chamber 50 when being flipped up, or covers the top of the accommodating chamber 50 when being flipped down.

(22) Preferably, the side plates 20 on the left and right sides each include two folding plates 21, the two folding plates 21 are arranged front and rear, a rear side wall of the folding plate 21 on the front side is hinged to a front side wall of the folding plate 21 on the rear side, a rear side wall of the folding plate 21 on the rear side is hinged to a side edge of the side plate 20 on the rear side, a front side wall of the folding plate 21 on the front side is hinged to a side edge of the side plate 20 on the front side, and when the folding plates 21 on the front and rear sides are swung and folded toward each other or swung and unfolded away from each other, the side plates 20 on the left and right sides are folded or unfolded front and rear.

(23) Specifically, the folding plate 21 on the front side extends rearward to form first abutting portions 211, the folding plate 21 on the rear side extends forward to form second abutting portions 212, and when the folding plates 21 on the front and rear sides are unfolded to form the same vertical flat surface, the first abutting portions 211 abut against a side wall of the folding plate 21 on the rear side facing the accommodating chamber 50, and the second abutting portions 212 abut against a side wall of the folding plate 21 on the front side facing the accommodating chamber 50, so that the folding plates 21 on the front and rear sides are only able to be swung and folded toward an inside of the accommodating chamber 50 and the folding plates 21 on the front and rear sides are only able to be swung toward an outside of the accommodating chamber 50 to at most form the same vertical flat surface. The folding plates 21 on the front and rear sides can only be swung and folded toward the inside of the accommodating chamber 50, and after being folded, the side plates 20 on the front and rear sides respectively cover the folding plates 21 on the front and rear sides, so that the size of the folded storage box 1 is reduced, which can reduce the occupied space during transportation, thereby reducing the transportation cost. Specifically, the first abutting portions 211 and the second abutting portions 212 may be staggered. It can be understood that the specific structures and shapes of the first abutting portions 211 and the second abutting portions 212 are not limited as long as the above functions can be met. The first abutting portions 211 and the second abutting portions 212 may be plate-like structures.

(24) Further, the side plates 20 on the left and right sides are provided with grooves 22, so that human hands are extendable into the grooves 22 to lift the whole storage box 1. Specifically, each folding plate 21 is provided with one groove 22, so that the storage box 1 can be lifted with both hands.

(25) Further, the side plate 20 on the front side is provided with a door opening 23, the door opening 23 is provided with a door 24, and the door 24 is capable of opening or blocking the door opening 23. Specifically, a bottom of the door 24 is hinged to a bottom edge of the door opening 23, so that the door 24 is flippable up along the hinges to block the door opening 23 or flippable down to open the door opening 23. Edges of the door 24 are provided with snap-fit protrusions, and edges of the door opening 23 except the bottom edge are provided with snap-fit grooves. When the door 24 blocks the door opening 23, the snap-fit protrusions may be pushed to be inserted into the snap-fit grooves, so that the door 24 and the door opening 23 form a snap fit, which prevents the door 24 from falling down and opening the door opening 23. It can be understood that the specific structure of the snap-fit protrusions is not limited as long as the function can be implemented.

(26) Further, left and right sides of bottoms of the side plates 20 on the front and rear sides are provided with swivel casters 25, so that the storage box 1 can be pushed conveniently.

(27) As shown in FIG. 9 to FIG. 12, the bottom of the side plate 20 on the front side horizontally protrudes rearward to form a snap-fit platform 27, the front side of the bottom plate 10 protrudes forward to form a plurality of wedge-shaped protrusions 13, a top surface of the protrusion 13 is a horizontal forward flat surface, and a front side surface of the protrusion 13 is a wedge surface inclined rearward. In the process of the bottom plate 10 being flipped down to a horizontal state, the front side surface of the protrusion 13 gradually comes into contact with the snap-fit platform 27, which stops the bottom plate 10 from being further flipped down. Since the whole storage box 1 is made of plastic, the snap-fit platform 27 is slightly deformed under the action of an external force to give way to the protrusion 13, so that the protrusion 13 passes through the snap-fit platform 27 and the snap-fit platform 27 abuts against the top surface of the protrusion 13, which stops the protrusion 13 from moving up and further stops the bottom plate 10 from moving up. Therefore, when the bottom plate 10 needs to be flipped up, the user needs to push the side plate 20 on the front side forward to make the snap-fit platform 27 deformed outward and give way to the protrusion 13, so that the protrusion 13 passes through the snap-fit platform 27, and further, the bottom plate 10 is further flipped up. Further, a bottom of the snap-fit platform 27 is provided with a plurality of vertical ribs 271 that are arranged left and right at intervals to improve the firmness of the snap-fit platform 27. Further, the vertical ribs directly abut against a front end of the bottom plate 10, so that the bottom plate 10 can abut against the side plate 20 on the front side when in the unfolded state.

(28) Specifically, the front side of the bottom plate 10 protrudes downward to form snap-fit plates 12, a bottom edge of the side plate 20 on the front side extends rearward horizontally through an arc transition, the arc transition is provided with corresponding slots 26, and the snap-fit plates 12 can be inserted into the slots 26 to limit the bottom plate 10 from wobbling.
