DETAILED DESCRIPTION
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
FIG. 1 shows an embodiment of a folding box 100 comprising a base 10, two opposite side boards 20, two opposite end boards 30, and a plurality of mounting apparatuses 40.
The base 10 comprises a substantially rectangular bottom plate 105, two side plates 101 substantially perpendicularly extending up from two opposite sides of the bottom plate 105, and two end plates 102 substantially perpendicularly extending up from two opposite ends of the bottom plate 105. An inner side of each side plate 101 defines a plurality of receiving slots 1012. A corresponding shaft 1013 is mounted and received in each receiving slot 1012. Each shaft 1013 is substantially parallel to a lengthwise direction of the side plates 101. An inner side of each end plate 102 defines a plurality of receiving slots 1022, a shaft 1023 is mounted in each receiving slot 1022, and each shaft 1023 is parallel to a lengthwise direction of the end plates 102.
Referring to FIG. 2 and FIG. 3, a first piece 201 and a second piece 203 substantially perpendicularly extend out from each end portion of an outer side of the side board 20. The first piece 201 and the second piece 203 are spaced from each other. The first piece 201 is closer to a corresponding end of the side board 20 than the second piece 203. Each first piece 201 and the corresponding second piece 203 cooperatively bound an installing slot 204. Each first piece 201 defines a though hole 205, and each second piece 203 defines a fastening hole 207 aligned with the corresponding through hole 205. Two spaced latching blocks 209 protrude out from each corresponding end of the side board 20. One latching block 209 is located above the corresponding through hole 205, and the other latching block 209 is located below the corresponding through hole 205. A plurality of resilient hooks 211 protrudes down from a bottom of each side board 20. The hooks 211 are arrayed along a lengthwise direction of the side board 20. Each hook 211 comprises a substantially C-shaped rotating portion 212 located at a bottom of the hook 211, and a resilient arcuate tab 215 located above the rotating portion 212.
A flange 31 substantially perpendicularly extends inward from each end of each end board 30. A protrusion 312 protrudes from an inner surface of each flange 31. Each protrusion 312 defines a latching hole 313. Two spaced positioning blocks 314 protrude from the inner surface of each flange 31. One positioning block 314 is located above the corresponding protrusion 312, and the other positioning block 314 is located below the corresponding protrusion 312. Two positioning holes 316 are defined in each flange 31. Each positioning hole 316 extends through a corresponding positioning block 314. A plurality of resilient hooks 32 protrudes down from a bottom of each end board 30. The hooks 32 are arrayed along a lengthwise direction of the end board 30. Each hook 32 comprises a substantially C-shaped rotating portion 321 located at a bottom of the hook 32, and an arcuate and resilient tab 325 located above the rotating portion 321.
Each mounting apparatus 40 comprises a first inserting member 41, a second inserting member 42, a threaded sleeve 44, and a resilient member 46. The first inserting member 41 comprises a threaded pole 411, an inserting portion 415 located at a first end of the threaded pole 411, and a positioning portion 413 located at a second end of the threaded pole 411 opposite to the inserting portion 415. The second inserting member 42 comprises a threaded pole 421, a stopping portion 422 located at a first end of the threaded pole 421, and an inserting portion 423 located at a second end of the threaded pole 421 opposite to the stopping portion 422. The threaded sleeve 44 defines a threaded through hole 441. In the embodiment, the first inserting member 41 and the second inserting member 42 are screws, the threaded sleeve 44 is a nut, and the resilient member 46 is a spring.
FIG. 4, FIG. 5, and FIG. 6 show assembled states of the folding box 100. Each threaded sleeve 44 and the corresponding resilient member 46 are received in the corresponding installing slot 204, and respectively aligned with the corresponding through hole 205 and fastening hole 207. The inserting portion 415 of each first inserting member 41 extends through the through hole 205 from an outer side of the corresponding first piece 201 to engage in the threaded through hole 441 of the corresponding threaded sleeve 44. The inserting portion 423 of each second inserting member 42 extends through the fastening hole 207 of the corresponding second piece 203 and the corresponding resilient member 46 to engage in the threaded through hole 441 of the corresponding threaded sleeve 44. Thus, the mounting apparatuses 40 are installed in the side boards 20. Each resilient member 46 is resiliently pressed between the second piece 203 and the corresponding threaded sleeve 44.
The hooks 211 of each side board 20 are inserted into the receiving slots 1012 of the corresponding side plate 101, such that the rotating portions 212 are rotatable about the shafts 1013. Each tab 215 prevents the corresponding hook 211 from detaching from the corresponding shaft 1013. The hooks 32 of each end board 30 are inserted into the receiving slots 1022 of the corresponding end plate 102, such that the shafts 1023 are rotatable about the rotating portions 321. Each tab 325 prevents the corresponding hook 32 from detaching from the corresponding shaft 1023. Thus, the side boards 20 are rotatable relative to the side plates 101, and the end boards 30 are rotatable relative to the end plates 102.
The end boards 30 are rotated about the corresponding shafts 1023, until the end boards 30 are substantially perpendicular to the base 10. Each second inserting member 42 is pulled away from the corresponding first piece 201, thus elastically deforming the corresponding elastic member 46 and moving the corresponding first inserting member 41 and the corresponding threaded sleeve 44 toward the corresponding second piece 203, until the positioning portion 413 is stopped by the corresponding first piece 201. The side boards 20 are rotated about the corresponding shafts 1013, until the latching blocks 209 are inserted into the corresponding positioning holes 316, and the positioning portions 413 are aligned with the corresponding latching holes 313. The second inserting members 42 are released, thus restoring the resilient members 46 to bias the threaded sleeves 44 and the corresponding first inserting members 41 to move, until the threaded sleeves 44 are stopped by the corresponding first pieces 201, and the positioning portions 413 are inserted into the corresponding latching holes 313. Thus, each end board 30 is perpendicularly latched to the side boards 20 by the mounting apparatuses 40. Therefore, the base 10, the side boards 20, and the end boards 30 cooperatively bound a receiving space for storing goods.
When folding the folding box 100, the second inserting members 42 are pulled away from the corresponding end boards 30, thus elastically deforming the resilient members 46. The threaded sleeves 44 and the first inserting members 41 are moved away from the corresponding end boards 30, until the positioning portions 413 are moved out of the corresponding latching holes 313. The side boards 20 are rotated toward the base 10, until the side boards 20 are supported on the base 10. The end boards 30 are rotated toward the base 10, until the end boards 30 are supported on the side boards 20. Thus, the folding box 100 is folded.
The side boards 20 and the end boards 30 can be rotated toward the base 10, and each end board 30 can be detachably latched to the side boards 20 by the mounting apparatuses 40. Thus, assembly and disassembly of the folding box 100 is convenient.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the present disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
