However, those skilled in the art will appreciate that in each embodiment of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0073] In the following description, for the purpose of illustrating the various disclosed embodiments, certain specific details are set forth in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with this application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0074] Unless the context requires otherwise, throughout the specification and claims, the word "comprise" and variations such as "include" and "have" should be construed in an open, inclusive sense, that is, should be interpreted to mean "including, but not limited to."

[0075] The following will describe in detail various embodiments of the present invention in conjunction with the accompanying drawings to provide a clearer understanding of the objectives, features and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0076] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0077] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally employed in its sense including "and / or" unless the context clearly dictates otherwise.

[0078] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0079] The following describes the frame of the container of the first embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 6 As shown, the container frame comprises a plurality of bases and a plurality of crossbeams 2. Each base has an identical structure and can therefore be manufactured using the same process. The multiple bases and crossbeams 2 are staggered and positioned end-to-end to form the frame. The crossbeams 2 have identical axial cross-sectional structures and can be of varying lengths. Therefore, each crossbeam 2 can be manufactured using the same process, thereby simplifying the manufacturing process.

[0080] In practice, the container frame comprises multiple bases and multiple crossbeams 2, each of which can be assembled to form a container frame. Each crossbeam 2 also has a uniform cross-sectional structure along the axial direction. Therefore, during container production, a large number of bases with the same structure can be manufactured using the same mold. This simplifies the manufacturing process for the crossbeams 2 and improves the convenience of container production.

[0081] Specifically, such as Figure 2 and Figure 5 As shown, crossbeam 2 is formed by extrusion. Extrusion is a process for processing billets, whereby the billet is extruded through a die orifice or slit under three-dimensional, non-uniform compressive stress, reducing its cross-sectional area and increasing its length to form the desired product. Therefore, a single extrusion die can be used to produce multiple crossbeams 2 with the same cross-section but varying lengths, further reducing processing costs. In actual production, container manufacturers can use the same extrusion die to produce crossbeams of varying lengths based on the needs of different customers, thereby reducing container production costs.

[0082] like Figure 1 、 Figure 2 and Figure 4 、 Figure 5 As shown, the frame is a rectangular frame, and the multiple bases are the multiple corners of the rectangular frame. Each base is connected to each crossbeam 2 to form a rectangular frame. Of course, in some embodiments, the frame can also be a polygonal shape, such as a pentagon, hexagon, triangle, etc., without departing from the scope of the present invention.

[0083] In addition, if Figure 2 and Figure 5 As shown, in order to keep the cross section of the crossbeam 2 unchanged while still being able to connect to the base, the crossbeam 2 has a hollow portion 21 therein, which extends in the axial direction of the crossbeam 2 and is open to both axial ends of the crossbeam 2. The base has a protrusion 17 that is operably snapped into the hollow portion 21.

[0084] Specifically, such as Figure 2 and Figure 5 As shown, the base has two protrusions 17 , which are arranged on both sides of the base and are connected to the two crossbeams 2 respectively.

[0085] Specifically, such as Figures 1 to 3 As shown, in some embodiments, the frame is a rectangular frame, the base in the frame is a first base 1, each first base 1 is two pairs, the two first bases 1 in each pair of first bases 1 have the same structure, and are arranged along the diagonal line of the first frame 6. The structures of each pair of first bases 1 are symmetrical to each other. Specifically, as Figures 1 to 3 As shown, the first base 1 in a pair of first bases 1 is a first left base 11, while the first base 1 in the other pair of first bases 1 is a first right base 12. The two first left bases 11 have the same structure and are arranged opposite each other along a diagonal line of the frame. The two first right bases 12 also have the same structure and are arranged opposite each other along the other diagonal line of the frame. The structures of the first left base 11 and the first right base 12 are symmetrical.

[0086] Since the structures of the two first left bases 11 and the two first right bases 12 are identical, a plurality of first left bases 11 and first right bases 12 can be produced using the same mold to be assembled into a frame.

[0087] Specifically, such as Figures 1 to 3 As shown, the first base 1 includes: a first upper plate 81 body 13, a second upper plate 81 body 14, a first connecting member 15, and a second connecting member 16. The first upper plate 81 body 13 and the second upper plate 81 body 14 are arranged perpendicular to each other, and the first upper plate 81 body 13 and the second upper plate 81 body 14 are respectively operably connected to two crossbeams 2, that is, the first upper plate 81 body 13 is connected to one crossbeam 2, and the second upper plate 81 body 14 is connected to the other crossbeam 2. The first connecting member 15 is arranged on the first upper plate 81 body 13 and can be connected to one side panel of the container. The second connecting member 16 is arranged on the second upper plate 81 body 14 and can be connected to the other side panel of the container.

[0088] It should be noted that the structures of the first upper plate 81 body 13 and the second upper plate 81 body 14, as well as the first connecting member 15 and the second connecting member 16 in the first left base 11 and the first right base 12 are the same, only the relative positions of the first upper plate 81 body 13 and the second upper plate 81 body 14 are different.

[0089] Specifically, the first connecting member 15 and the second connecting member 16 are both hinges. Of course, in some embodiments, the first connecting member 15 and the second connecting member 16 may not be hinges, but an ordinary fixing member.

[0090] Specifically, such as Figures 4 to 6 As shown, in some embodiments, the frame is a rectangular frame, the base in the frame is a second base 3, each second base 3 is two pairs, the two second bases 3 in each pair of second bases 3 have the same structure, and are arranged along the diagonal line of the second frame 7. The structures of each pair of second bases 3 are symmetrical to each other. Specifically, as Figures 4 to 6 As shown, the second base 3 in one pair of second bases 3 is a second left base 31, while the second base 3 in the other pair of second bases 3 is a second right base 32. The two second left bases 31 have the same structure and are arranged opposite each other along a diagonal line of the frame. The two second right bases 32 also have the same structure and are arranged opposite each other along the other diagonal line of the frame. The second left base 31 and the second right base 32 have symmetrical structures.

[0091] Since the structures of the two second left bases 31 and the two second right bases 32 are the same, a plurality of second left bases 31 and second right bases 32 can be produced using the same mold to assemble into a frame. Figure 1 and Figure 4 As shown, both ends of the same beam 2 are connected to the first upper plate 81 body 13 or the second upper plate 81 body 14 , that is, both ends of the same beam 2 are connected to the first upper plate 81 body 13 or the second upper plate 81 body 14 .

[0092] Specifically, such as Figures 4 to 6 As shown, the second base 3 includes a first lower plate 82 body 33, a second lower plate 82 body 34, a lower connecting member 35, and a clamping member 36. The first lower plate 82 body 33 and the second lower plate 82 body 34 are arranged perpendicular to each other and are each operably connected to the two crossbeams 2. The lower connecting member 35 is disposed on the first lower plate 82 body 33 and can be connected to a side panel of the container. The clamping member 36 is disposed on the first lower plate 82 body 33 and / or the second lower plate 82 body 34 and can be connected to the bottom plate 5 of the container to secure the bottom plate 5 of the container.

[0093] It should be noted that the structures of the first lower plate 82 body 33 and the second lower plate 82 body 34 in the second left base 31 and the second right base 32, as well as the lower connecting member 35 and the clamping member 36 are the same, only the relative positions between the first lower plate 82 body 33 and the second lower plate 82 body 34 are different.

[0094] It should be noted that in the same frame, the cross-sections of the beams 2 are the same, but in different frames, the cross-sections of the beams 2 may be different.

[0095] Specifically, the lower connecting member 35 is also a hinge.

[0096] like Figure 3 and Figure 6 As shown, the hinge comprises a fixed portion 41, a first rotating shaft 42, and a second rotating shaft 43. The fixed portion 41 defines a mounting slot 411 that extends through the fixed portion 41, and the side edges of the side panels are operably fixed within the mounting slot 411. The first rotating shaft 42 and the second rotating shaft 43 are coaxially disposed and are disposed on opposite sides of the fixed portion 41 along the direction through which the mounting slot 411 extends. The first rotating shaft 42 and the second rotating shaft 43 are rotatably connected to one of the first upper plate 81 body 13, the second upper plate 81 body 14, and the first lower plate 82 body 33, respectively, about the axis of the first rotating shaft 42 and the second rotating shaft 43. That is, when the hinge is located on the first upper plate 81 body 13, the first rotating shaft 42 and the second rotating shaft 43 in the hinge are rotatably connected to the first upper plate 81 body 13. Similarly, the same applies when the hinge is located on the second upper plate 81 body 14 or the first lower plate 82 body 33.

[0097] Since the first connecting member 15 , the second connecting member 16 and the lower connecting member 35 have the same structure, the convenience of frame processing can be further improved.

[0098] Specifically, such as Figure 3 As shown, along the axial direction of the frame, the first connecting member 15 is located below the second connecting member 16. Figures 1 to 3 As shown, a first upper groove 131 is formed on the first upper plate 81 body 13, and two first upper connecting holes 132 are formed on both sides of the first upper groove 131 along the axial direction of the first upper plate 81 body 13 perpendicular to the frame. The first rotating shaft 42 and the second rotating shaft 43 are rotatably located in the two first upper connecting holes 132. In addition, as shown Figures 1 to 3 As shown, the second upper plate 81 body 14 defines a second upper groove 141, and the second upper groove 141 defines two second upper connection holes 142 on both sides of the second upper plate 81 body 14 perpendicular to the axial direction of the frame. The first rotating shaft 42 and the second rotating shaft 43 of the hinge are rotatably located in the two second upper connection holes 142. Similarly, as Figures 4 to 6 As shown, a first lower groove 331 is also provided on the first lower plate 82 body 33. At the same time, two first lower connecting holes 332 are provided on both sides of the first lower groove 331 along the axial direction of the first lower plate 82 body 33 perpendicular to the frame. The first rotating shaft 42 and the second rotating shaft 43 of the hinge are respectively rotatably located in the two first lower connecting holes 332.

[0099] In addition, if Figure 6 As shown, along the axial direction of the frame, the clamping member 36 is located below the lower connecting member 35. The clamping member 36 includes: a first clamping plate 361 and a second clamping plate 362, which are arranged opposite to each other along the axial direction of the frame and are spaced apart from each other. The bottom plate 5 of the container is clamped between the first clamping plate 361 and the second clamping plate 362. In this embodiment, the first clamping plate 361 and the second clamping plate 362 are both connected to the first lower plate 82 body 33 and the second lower plate 82 body 34, and the first clamping plate 361 and the second clamping plate 362 are located below the lower connecting member 35. Of course, in some embodiments, the first clamping plate 361 and the second clamping plate 362 can be only provided on the first lower plate 82 body 33 or the second lower plate 82 body 34.

[0100] During the production process of the container, the manufacturer can use the same mold to produce a large number of first bases 1, and use another mold to produce a large number of second bases 3, and at the same time use the same extrusion mold to produce a large number of beams 2 of different lengths. According to the needs of different customers, the beams 2 of different lengths can be assembled with each first base 1 or each second base 3 to form frames of different sizes. In this process, since almost all components of the frame are manufactured using the same mold, the manufacturer's production process can be greatly reduced, and production costs can also be reduced.

[0101] The second embodiment of the present invention provides a turnover container, such as Figures 7 to 10 As shown, the turnover container comprises two frames of the container of the first embodiment, two pairs of side panels, and a bottom panel 5. The two frames are coaxially arranged opposite each other and are rectangular. The two pairs of side panels are located between the two frames and are connected to the bases in each frame. The bottom panel 5 is located in either frame, with the base connected to each base in the frame, and is arranged perpendicular to each side panel.

[0102] Specifically, each side panel and each bottom panel 5 are formed through an extrusion process. Extrusion molding is a method for processing a blank, wherein the blank is extruded from a die orifice or slit under three-dimensional nonuniform compressive stress, reducing its cross-sectional area and increasing its length to form the desired product. Therefore, a single extrusion die can be used to process numerous sheets of identical cross-section but varying lengths, further reducing processing costs. In actual production, container manufacturers can use extrusion dies to produce side panels and bottom panels 5 of varying lengths based on the needs of different customers. These side panels, bottom panels 5, and frames can then be assembled into containers of varying sizes, thereby reducing container production costs.

[0103] Specifically, such as Figures 7 to 10 As shown, one of the two frames is a first frame 6, and the other is a second frame 7. The bases in the first frame are first bases 1, each of which has an identical structure. The bases in the second frame 7 are second bases 3, each of which has an identical structure. Since the structures of the first bases 1 and the second bases 3 are identical, the container production process can be further simplified. Of course, in some embodiments, only the first bases 1 in the first frame 6 may have an identical structure, or only the second bases 3 in the second frame 7 may have an identical structure, as long as it does not depart from the scope of the present invention.

[0104] like Figures 7 to 10 As shown, the first frame 6 has four first bases 1 and four crossbeams 2, and the first frame 6 is a rectangular frame. The second frame 7 also has four second bases 3 and four crossbeams 2, and the second frame 7 is a rectangular frame.

[0105] like Figures 7 to 10 As shown, the structures of the first base 1 and the second base 3 are described in detail in the first embodiment above, and to avoid repetition, they will not be described here one by one. However, it should be noted that in this embodiment, the first upper plate 81 body 13 and the first lower plate 82 body 33 are arranged relative to each other along the height direction of the container, and the second upper plate 81 body 14 and the second lower plate 82 body 34 are also arranged relative to each other along the height direction of the container.

[0106] Specifically, the first connecting member 15, the second connecting member 16 and the lower connecting member 35 are all hinges, and along the height direction of the turnover container, the first connecting member 15 is located below the second connecting member 16. Since the structure of the hinge has been introduced in detail in the first embodiment, it will not be repeated in this embodiment.

[0107] In addition, if Figures 7 to 15 As shown, one pair of the two pairs of side panels is a pair of first side panels 8, which are respectively connected to the first connecting members 15 and the lower connecting members 35, and the other pair of side panels is a pair of second side panels 9, which are respectively connected to the second connecting members 16.

[0108] In addition, if Figure 14 As shown, each first side panel 8 in a pair of first side panels 8 includes: an upper panel 81 and a lower panel 82 arranged in sequence along the height direction, the upper panel 81 and the lower panel 82 are hinged to each other, and relative rotation can occur between the upper panel 81 and the lower panel 82, the upper panel 81 is connected to the first connecting member 15 in the first frame 6, and the lower panel 82 is connected to the lower connecting member 35 in the second frame 7.

[0109] The pair of second side plates 9 are located inside the pair of first side plates 8 , and the lower ends of the pair of second side plates 9 are detachably engaged with the second base 3 in the second frame 7 .

[0110] In addition, if Figures 9 to 12 As shown, in order to allow the lower ends of the pair of second side plates 9 to be detachably connected to the second base 3 in the second frame 7, as shown in FIG. Figures 9 to 12 As shown, the turnover container also includes a plurality of lock buckles 10, specifically, as shown in FIG. Figures 4 to 6 As shown, a latch hole 341 is provided on the body 34 of the second lower plate 82. The lock buckle 10 includes a clamping portion 101 and a latch protrusion 102. The clamping portion 101 has a groove 1011 that passes through the clamping portion 101. The lower end of the second side plate 9 is operably fixed in the groove 1011. The lower end of the second side plate 9 can be detachably engaged in the groove 1011 or fixed in the groove 1011 by welding. The latch protrusion 102 is provided on the clamping portion 101 and is arranged in a longitudinal direction perpendicular to the groove 1011. The latch protrusion 102 is operably fixed in the latch hole 341 on the body 34 of the second lower plate 82.

[0111] Specifically, the lock buckle 10 is also formed by an extrusion process.

[0112] Since a container often requires multiple sets of molds to complete production, a change in the container's volume often means an increase in the number of molds required, which increases investment costs. Therefore, a modular turnover container is needed that can be assembled into a series of turnover containers of different volumes by cutting and assembling accessories produced by a few molds. In this embodiment, since each beam 2 is formed using an extrusion process, its process characteristics are: the cross-section of the product is fixed by the forming mold but the length can be adjusted as needed, so that the size of the container can be changed by adjusting the length of the beam 2. At the same time, the two pairs of side panels and the bottom plate 5 also adopt an extrusion molding process, which is characterized by: the thickness of the side panels and the bottom plate 5 is fixed by the forming equipment and the mold, but their external dimensions and shape can be adjusted as needed, which makes it very simple and convenient to adjust the size of the container, thereby meeting the needs of various customers.

[0113] In addition, the steps for folding the turnover container in this embodiment are as follows: Figures 13 to 15 As shown, first, remove the protrusions 102 in the lock buckles 10 at the lower ends of the pair of second side panels 9 from the two locking holes 341 respectively, and the lower ends of the pair of second side panels 9 are unlocked. Push the pair of second side panels 9 upward and rotate them until the pair of second side panels 9 are basically parallel to the bottom plate 5. Figure 14 As shown, since the upper plate 81 and the lower plate 82 in a pair of side plates are relatively hinged, the first frame 6 can be pressed downward so that the upper plate 81 and the lower plate 82 rotate relative to each other until the first frame 6 and the second frame 7 are stacked together. The stacking of the turnover containers can be completed through the above operations.

[0114] In addition, it should be noted that when the turnover container is in an open state, since the pair of second side plates 9 are located on the inner side of the pair of first side plates 8, the pair of second side plates 9 support the pair of first side plates 8, which can prevent the upper plate 81 and the lower plate 82 in the pair of first side plates 8 from rotating relative to each other when the turnover container is in an open state.
