(13) The folding box 1 is formed by cutting and folding a thinner cardboard integrally, and the folding box 1 comprises a bottom board 10, front and rear side boards 20 extending outwardly from the front and rear sides of the bottom board 10 respectively, left and right side boards 30 extending from the left and right sides of the bottom board 10 respectively, and a linkage plate 40 disposed at four corners formed by the intersections of the front and rear side boards 20 and the left and right side boards 30 separately and the linkage plates 40 are coupled to one another.

(14) Left and right reverse folding plates 31 extend from the outer edges of the left and right side boards 30 respectively, and the left and right reverse folding plates 31 are reversely folded and adhered onto the corresponding left and right side boards 30, or as shown in the figure, a fixed support plate 50 with a thickness greater than the cardboard of the folding box 1 is disposed at the inner sides of the left and right side boards 30 separately, and the left and right reverse folding plates 31 are reversely folded and adhered to the corresponding inner side of the fixed support plate 50.

(15) In FIGS. 5 and 6, the left and right side boards 30 of the folding box 1 and the corresponding fixed support plate 50 are folded towards the center of the bottom board 10 and superimposed on the top of the bottom board 10, and each linkage plate 40 is folded towards the center of the front and rear side boards 20 and fixed to the top of front and rear side boards 20 to define a flat half-folded state.

(16) The traction support board 2 has a thickness greater than the cardboard of the folding box 1 and has two movable support plates 60 corresponding to the front and rear side boards 20 of the folding box 1, and a bottom support plate 70 corresponding to the bottom board 10 of the folding box 1, and the two movable support plates 60 and the bottom support plate 70 are divided and formed by both front and rear fold lines 61, and a central fold line 71 is formed at the center of the bottom support plate 70 and parallel to the front and rear fold lines 61, and a lifting portion 72 is disposed at the center of the bottom support plate 70 and provided for a user to apply a force.

(17) The traction support board 2 is superimposed on the left and right side boards 30 of the folding box 1 in the half-folded state and the top of the plurality of linkage plates 40, and front and rear reverse folding plates 21 extend from the outer edges of the front and rear side boards 20 of the folding box 1 respectively and the front and rear reverse folding plates 21 may be reversely folded and fixed onto the two movable support plates 60 of the traction support board 2.

(18) In FIGS. 7 and 8, a user can lift the lifting portion 72 of the traction support board 2, and grip the bottom support plate 70 to apply a force, so that the bottom support plate 70 is bent and uplifted along the central fold line 71, and the two movable support plates 60 are bent upwardly along both front and rear fold lines 61 with respect to the bottom support plate 70, while driving the front and rear side boards 20 to stand up with respect to the bottom board 10, and the plurality of linkage plates 40 drag the left and right side boards 30 to be erected from the corresponding fixed support plate 50.

(19) In FIGS. 9 and 10, after the front and rear side boards 20 and the left and right side boards 30 stand up, the linkage plate 40 is superimposed on the inner sides of the front and rear side boards 20, and the user may press the bottom support plate 70 of the traction support board 2 to flatly superimpose the bottom support plate 70 onto the top of the bottom board 10, and the two movable support plates 60 are folded reversely and superimposed onto the front and rear side boards 20 and the corresponding inner sides of the plurality of linkage plates 40, so as to assemble the folding box 1 and the traction support board 2 quickly to form a storage box in a three-dimensional state and having an accommodation space.

(20) When the storage box is not in use, the traction support board 2 may be lifted from the top of the bottom board 10 of the folding box 1 in a sequence as shown in FIGS. 10 to 7 and the traction support board 2 is removed in a reverse direction to let the folding box 1 return to its flat half-folded state. In addition, the traction support board and the folding box are made of cardboards of different thicknesses, and such arrangement not just reduces the material cost only, but the traction support board also can reinforce the structural strength of the folding box to overcome the drawbacks of the conventional storage box such as the incapability of being folded easily for storage, the inconvenient assembling procedure, and the insufficient structural strength.

(21) When the users are familiar with the assembling procedure of the storage box, the users can lift the traction support board by one hand as shown in the figure, so as to assemble the storage box more quickly. In practice, the lifting portion 72 may be a drawstring (as shown in the figure), or a buckle (not shown in the figure), or a through hole (not shown in the figure) dug from the bottom support plate, or any other component provided for the users to apply a force.

(22) In FIG. 11, the lifting portion is a lift-up force applying plate 73 formed by a semicircular cut line 74 disposed at the center of the central fold line 71 of the bottom support plate 70, so that the lift-up force applying plate 73 can be erected along the semicircular cut line 74 to stand up with respect to the bottom support plate 70 and provided for the users to lift. On the other hand, when the front and rear side boards 20 and the left and right side boards 30 are erected, and the bottom support plate 70 is flatly superimposed onto the top of the bottom board 10, the lift-up force applying plate 73 can also be flatly superimposed onto the top of the bottom board 10, so as to maintain a flat inner bottom surface of the whole storage box.

(23) In addition, the traction support board 2 has a second fold line 62 defined separately on the two movable support plates 60 and disposed near and parallel to the front and rear fold lines 61. When the folding box 1 comes with a relatively larger size, the two second fold lines 62 can assist the two movable support plates 60 to be folded reversely and superimposed onto the front and rear side boards 20 and the inner sides of the plurality of linkage plates 40, so as to facilitate the users to assemble the storage box.

(24) In FIGS. 3 and 4, each linkage plate 40 has an oblique crease 41 extending in a diagonal direction, so that the linkage plate 40 is divided into a first folding plate 42 coupled to the front and rear side boards 20 and a second folding plate 43 coupled to the left and right side boards 30, and the outer side edge of the first folding plate 42 has a positioning plate 44 facing the front and rear side boards 20, and a cutting line 45 is defined at the intersection position of the positioning plate 44 and the first folding plate 42, wherein the cutting line 45 extends from the outside to the inside until it reaches the oblique crease 41, so that the positioning plate 44 is folded towards the front and rear side boards 20 by using the oblique crease 41 as the baseline.

(25) When the folding box 1 is in the flat half-folded state, the inner sides of the first and second folding plates 42, 43 of each linkage plate 40 are superimposed onto the adjacent front and rear side boards 20 respectively, and the positioning plate 44 is folded along the oblique crease 41 and then the outer side of the positioning plate 44 is adhered and fixed onto the front and rear side boards 20.

(26) When the front and rear side boards 20 are erected with respect to the bottom board 10, the first and second folding plates 42, 43 of each linkage plate 40 are folded along the oblique crease 41 and then superimposed onto the corresponding inner sides of the front and rear side boards 20, so as to drive the left and right side boards 30 to be erected with respect to the bottom board 10. During the process of the linkage plate 40 driving the left and right side boards 30 to be erected, the positioning plate 44 folded reversely and fixed to the front side board or the rear side board can change the direction of the action force exerted onto the first folding plate 42 linked with the second folding plate 43 and reduce the resistance between the first and second folding plates 42, 43. Therefore, the linkage plate 40 can smoothly drag the left and right side boards 30 to be erected.

(27) In FIG. 11, the linkage plate 40 may also adopt a common folding method. Similarly, a user can lift the traction support board 2 to drive the flat folding box to be assembled quickly into a three-dimensional state.

(28) While the present invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present invention set forth in the claims.
