[0042] In this embodiment, firstly, the base plate 21 is folded upward along the front indentation to form a front baffle 23 at the front end of the base plate 21. Next, the left and right sides of the base plate 21 are folded upward along the front indentation to form front side plates 22 on the left and right sides of the base plate 21, respectively. Then, since front folding grooves 51 are laterally provided on the left and right sides of the front indentation, and the length of the front folding grooves 51 is equal to the width of the front side plates 22, after the front baffle 23 and front side plates 22 are folded upward, the left and right sides of the front baffle 23 are folded from front to back. After the second front fold 231 passes through the front limiting groove 53, the first front fold and the second front fold 231 abut against the inner and outer side walls of the front side panel 22 respectively. That is, when the second front fold 231 passes through the front limiting groove 53 and abuts against the inner side wall of the front side panel 22, the first front fold abuts against the outer side wall of the front side panel 22. Or, when the second front fold 231 passes through the front limiting groove 53 and abuts against the outer side wall of the front side panel 22, the first front fold abuts against the inner side wall of the front side panel 22. Thus, the folding of the floor box 2 can be completed.

[0043] In this embodiment, the connecting plate 3 is first folded upward along the first indentation 11 to form the connecting plate 3 at the middle position of the box body 1. Then, since there are middle side indentations on the left and right sides of the connecting plate 3, the left and right ends of the connecting plate 3 are folded upward along the middle side indentations to form middle side plates on the left and right sides of the connecting plate 3. After the connecting plate 3 is folded upward, the two middle side plates are folded from back to front. Then, the first middle fold edge 31 is passed through the middle limiting groove 64 to make the first middle fold... The first middle fold edge 31 and the second middle fold edge 32 are respectively staggered and abut against the inner and outer side walls of the front side plate 22. That is, when the first middle fold edge 31 passes through the middle limiting groove 64 and abuts against the inner side wall of the front side plate 22, the second middle fold edge 32 abuts against the outer side wall of the front side plate 22. Or when the first middle fold edge 31 passes through the middle limiting groove 64 and abuts against the outer side wall of the front side plate 22, the second middle fold edge 32 abuts against the inner side wall of the front side plate 22, thereby completing the folding of the connecting plate 3.

[0044] In this embodiment, firstly, the top plate 41 is folded upward along the rear indentation to form a rear baffle 43 at the rear end of the top plate 41. Next, the left and right ends of the top plate 41 are folded upward along the rear indentation to form rear side plates 42 on the left and right sides of the top plate 41, respectively. Furthermore, since rear folding grooves 71 are laterally provided on the left and right sides of the rear indentation, and the length of the rear folding grooves 71 is equal to the width of the rear side plates 42, after the rear baffle 43 and rear side plates 42 are folded upward, the left and right ends of the rear baffle 43 fold from back to front. After the second rear folded edge 731 passes through the front limiting groove 53, the first rear folded edge and the second rear folded edge 731 are alternately abutted against the inner and outer side walls of the rear side plate 42. That is, when the second rear folded edge 731 passes through the rear limiting groove 73 and abuts against the inner side wall of the rear side plate 42, the first rear folded edge abuts against the outer side wall of the rear side plate 42. Or when the second rear folded edge 731 passes through the rear limiting groove 73 and abuts against the outer side wall of the rear side plate 42, the first rear folded edge abuts against the inner side wall of the rear side plate 42, thereby completing the folding of the top box 4.

[0045] Furthermore, since the sum of the widths of the base plate 21 and the two front side plates 22 is less than the sum of the widths of the top plate 41 and the two rear side plates 42, it is convenient to place the folded top box 4 over the outside of the bottom box 2. This allows the rear baffle 43 to abut against the outside of the front baffle 23. Simultaneously, the front baffle 23 and the connecting plate 3 are positioned opposite each other, and the two rear side plates 42 abut against the outside of the two front side plates 22 respectively. Thus, the assembly of the top and bottom boxes 2 can be completed without connecting nails, effectively improving production assembly efficiency and further enhancing the tightness of the product packaging. The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
