[0027] Example 1:
[0028] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.
[0029] A side-mounted folding container consists of an independently set top plate 60 and a main body. The top plate 60 is fixed to the upper end of the inner corner post of the main body by a pin when folded and unfolded, which facilitates better stacking and transportation. The total height of the folded container is 658mm.
[0030] The main body includes a bottom plate 10, a left side plate 20, a front door 30 and a rear door 40 arranged side by side, and a right side plate 50, which are hinged and folded from bottom to top.
[0031] The bottom plate 10 has several left hinge seats 11 arranged in a longitudinal array on the inner side of the baffle on the left side, and several left pads 21 are arranged in a corresponding array on the bottom end face of the left side plate 20. The left side plate 20 is hinged to the bottom plate 10 through the left pads 21 and the left hinge seats 11, and can be flipped or unfolded left and right with the axis of the left hinge seats 11 as the axis.
[0032] The front end of the left side panel 20 is provided with a first front hinge 22, the other end of the first front hinge 22 is provided with a front transition plate 23, the other end of the front transition plate 23 is provided with a second front hinge 24, and the other end of the second front hinge 24 is connected to the left side of the front door 30. The front door 30 and the left side panel 20 are hinged by the first front hinge 22, the front transition plate 23 and the second front hinge 24. The front door 30 and the left side panel 20 are folded outward or inward about the axis of the first front hinge 22, so that the outer or inner side of the front transition plate 23 is in contact with the left side panel 20. Then, the front door 30 is folded outward or inward about the axis of the second front hinge 24, so that the front door 30 is separated from or in contact with the bottom plate 10 and the right side panel 50. After the front transition plate 23 is flipped and folded, it forms a triangular structure with the first front hinge 22 and the second rear hinge 27 and is stored inside the base plate 10. That is, when the folded front transition plate 23, the first front hinge 22 and the second rear hinge 27 are folded, they do not extend beyond the front edge of the base plate 10, which facilitates transportation and avoids damage to critical parts.
[0033] The rear end of the left side panel 20 is provided with a first rear hinge 25. The other end of the first rear hinge 25 is provided with a rear transition plate 26. The other end of the rear transition plate 26 is provided with a second rear hinge 27. The other end of the second rear hinge 27 is connected to the left side of the rear door 40. The rear door 40 and the left side panel 20 are hinged by the first rear hinge 25, the rear transition plate 26 and the second rear hinge 27. The rear door 40 and the left side panel 20 are folded outward or inward about the axis of the first rear hinge 25, so that the outer or inner side of the rear transition plate 26 is in contact with the left side panel 20. Then, the rear door 40 is folded outward or inward about the axis of the second rear hinge 27, so that the rear door 40 is separated from or in contact with the bottom plate 10 and the right side panel 50. After the rear transition plate 26 is flipped and folded, it forms a triangular structure with the first rear hinge 25 and the second rear hinge 27 and is stored inside the base plate 10. That is, when the rear transition plate 26, the first rear hinge 25 and the second rear hinge 27 are folded, they do not extend beyond the rear end edge of the base plate 10, which facilitates transportation and avoids damage to critical parts.
[0034] The right side of the base plate 10 is provided with several right hinge seats 12 arranged in a longitudinal array. The right hinge seats 12 are raised, and the effective height of the right hinge seats 12 is 170mm, meaning that the height difference between the left side plate 20 and the right side plate 50 after they are unfolded is 170mm. The bottom surface of the right side plate 50 is provided with several right pads 51 arranged in a corresponding array. The base plate 10 and the right side plate 50 are hinged through the right hinge seats 12 and the right pads 51. The base plate 10 and the right side plate 50 can be flipped or unfolded left and right about the axis of the right hinge seats 12. The bottom of the right side of the base plate 10 is provided with several right support plates 13 arranged in an array. The right support plates 13 are located between two adjacent right hinge seats 12. After the right side plate 50 is unfolded, the right support plates 13 are below the right hinge seats 12. The right support plates 13 are aligned with the corner posts and are consistent with the overall structure of the main body without any abnormal protrusion.
[0035] When folding, first remove the top plate 60, then remove the fixing bolts one by one. Flip the front door 30 and rear door 40 to the left using the second front hinge 24 and the second rear hinge 27 as axes. Then, together with the front transition plate 23 and the rear transition plate 26, flip them to the left using the first front hinge 22 and the first rear hinge 25 as axes, and attach them to the outer side of the left side plate 20. Flip the left side plate 20 to the right to attach it to the bottom plate 10, and then flip the right side plate 50 to the left to attach it to the left side plate 20. Finally, stack the top plate 60 on top.
[0036] When unfolding, remove the top plate 60, unfold the right side plate 50 and the left side plate 20 in sequence, and then flip the front door 30 and the rear door 40 to the right together with the front transition plate 23 and the rear transition plate 26. Then, continue to flip only the front door 30 and the rear door 40 until the main body is shaped. Finally, put the top plate 60 back on and insert bolts to fix it.
[0037] Example 2:
[0038] The difference from Embodiment 1 is that the left side panel 20 and the right side panel 50 are swapped, the relevant hinges are modified, the left hinge seat 11 is raised, and the front door 30 and the rear door 40 are hinged to the right side panel 50. The front door 30 and the rear door 40 still do not have an outward-folding design. The front door 30 and the right side panel 50 fold or unfold around the front edge of the right side panel 50, and the rear door 40 and the right side panel 50 fold or unfold around the rear edge of the right side panel 50. The structural schemes of Embodiment 2 and Embodiment 1 are not fundamentally different, and there is no particularly obvious comparison of advantages and disadvantages.
[0039] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
