Description

Technical Field

[0001] The present invention relates to the technical field of temporary outdoor facilities, and in particular to a hinge structure of a folding container house, a folding container house, and a folding method and an opening method of the folding container house. Background Art

[0002] There is a kind of container house used as a temporary outdoor place. This kind of container house is a fixed container house, which includes a base, a roof, four columns connected between the corners of the base and the roof, and multiple walls. The walls can be made of iron walls or glass walls according to needs.

[0003] The existing problems with fixed container houses are that they are large in size, difficult to transport, and the transportation methods are limited and cannot be transported over long distances, such as by sea or rail. Summary of the Invention

[0004] A first object of the present invention is to provide a hinge structure for a foldable container house that is easy to transport.

[0005] A second object of the present invention is to provide a foldable container house that is easy to transport.

[0006] A third object of the present invention is to provide a folding method for a foldable container house that is easy to transport.

[0007] A fourth object of the present invention is to provide a method for opening a foldable container house that is easy to transport.

[0008] The hinge structure of the folding box house provided by the first purpose of the present invention includes a first hinge and a second hinge hinged to the rotation axis; the first hinge includes a first rotating shaft body, and the second hinge includes a second rotating shaft body, and the first rotating shaft body and the second rotating shaft body are both perpendicular to the rotation axis; when the hinge structure is in an extended state, the first rotating shaft body and the second rotating shaft body are coaxial with each other, and the first hinge limits the rotation of the second hinge.

[0009] The folding mechanism is a series of steps in which the first hinge is mounted on the support frame, the second hinge is mounted on the support frame, and the folding mechanism is a series of steps in which the first hinge is mounted on the support frame, the second hinge is mounted on the support frame, and the folding mechanism is a series of steps in which the first hinge is mounted on the support frame, the second hinge is mounted on the support frame, and the folding mechanism is a series of steps in which the first hinge is mounted on the support frame, and the folding mechanism is a series of steps in which the

[0010] A further solution is that a first threaded section is provided on the extended end of the first rotating shaft body, and a second threaded section is provided on the extended end of the second rotating shaft body.

[0011] As can be seen from the above, taking the first rotating shaft body as an example, after the first rotating shaft body passes through the connecting body of the lower column, the first threaded section cooperates with the first nut, thereby ensuring the stability of the connection between the first hinge and the lower column.

[0012] The foldable container house provided by the second purpose of the present invention includes a base and a roof; the foldable container house also includes an upper column, a lower column and the above-mentioned hinge structure; the top of the upper column is rotatably connected to the roof, and the bottom of the lower column is rotatably connected to the base, the hinge structure is in an extended state, the first rotating shaft body is rotatably connected to the top of the lower column, and the second rotating shaft body is rotatably connected to the bottom of the upper column; the foldable container house can be transformed from a transitional form to a usage form; when the foldable container house is in the transitional form, the hinge structure is located in a first rotation position, and the first hinge, the second hinge, the upper column and the lower column are all located on the same side of the rotation axis; when the foldable container house is in the usage form, the hinge structure is located in a second rotation position, the first hinge and the second hinge are limited to fit on the first side of the rotation axis, the upper column and the lower column abut each other on the second side of the rotation axis, and the first side and the second side are respectively opposite sides of the rotation axis.

[0013] As can be seen from the above scheme, when the folding container house is in the transitional configuration, the first and second hinges have rotational freedom, allowing the upper and lower columns to fold. When the folding container house is in the use configuration, the rotation between the first and second hinges is completely restricted, and the upper and lower columns are securely fitted together to prevent tipping. The folding container house's form transition is based on the rotation of the hinged structure. The folding container house's ability to transform between its use and folded configurations facilitates its transportation, and the form transition is simple, improving assembly efficiency.

[0014] A further solution is that the second rotating shaft body and the upper column are slidably fitted along the axial direction of the second rotating shaft body; a storage groove is formed at the bottom of the upper column; when the folding box house changes from a transitional form to a usage form, the upper column slides relative to the hinge structure; when the folding box house is in the transitional form, the rotation axis is located outside the storage groove; when the folding box house is in the usage form, the rotation axis is located inside the storage groove.

[0015] As can be seen from the above, this setting allows the hinge structure of the folding container house to be hidden in the column when it is in use, thereby effectively protecting key components and preventing safety accidents caused by misoperation by others.

[0016] A further solution is that the folding box house also includes a first nut and a second nut; the lower column has a first connecting body, which is provided with a first through hole; the upper column has a second connecting body, which is provided with a second through hole; after the first rotating shaft body passes through the first through hole, the first threaded section cooperates with the first nut; after the second rotating shaft body passes through the second through hole, the second threaded section cooperates with the second nut, and the second rotating shaft body slides in cooperation with the second connecting body.

[0017] As can be seen from the above, this arrangement can effectively improve the coordination stability between the hinge structure, the lower column and the upper column.

[0018] A further solution is that the upper column has a blocking wall, which is located at the periphery of the storage groove; when the folding box room is in use, the blocking wall prevents the hinge structure from rotating relative to the upper column.

[0019] As can be seen from the above, this setting effectively prevents the hinge structure from rotating, further improving the safety of the folding container house.

[0020] A further solution is that the angle through which the hinge structure rotates from the first rotation position to the second rotation position is 180 degrees.

[0021] As can be seen from the above, this setting makes it easier for workers to determine the correct rotation position when rotating the hinge structure, reduces the difficulty of operation, and improves the connection stability between the upper column, the hinge structure and the lower column.

[0022] A further solution is to form a storage space with an opening facing downward on the roof; the folding container house can be transformed from a transitional form to a folding form. When the folding container house is in the folding form, the lower column and the upper column overlap, and the upper column is located in the storage space.

[0023] As can be seen from the above, this arrangement provides good physical protection for the upper columns and other structures stored in the roof, thereby improving product quality.

[0024] The folding method of the folding container house provided by the third purpose of the present invention is applied to the above-mentioned folding container house; the folding method includes lifting the roof and upper column of the folding container house in the use form so that the hinge structure is exposed between the upper column and the lower column; rotating the hinge structure in the second rotation position to the first rotation position relative to the lower column; driving the first hinge and the second hinge to rotate relative to each other.

[0025] The opening method of the folding container house provided by the fourth purpose of the present invention is applied to the above-mentioned folding container house; the opening method includes lifting the roof and upper columns of the folding container house in the folded form to transform the folding container house into a transitional form; rotating the hinged structure in the first rotation position to the second rotation position relative to the lower column; and lowering the roof and upper columns of the folding container house until the upper columns abut against the lower columns.

[0036] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the folding container house embodiment of the present invention from the first perspective. Figure 2 This is a structural diagram of an embodiment of a foldable container house according to the present invention, viewed from a second perspective. The foldable container house comprises a base 11, a roof 12, end walls 21, side walls 22, upper columns 32, lower columns 31, and a hinge structure 4. A lower column 31 is mounted at each of the four corners of the base 11, and an upper column 32 is mounted at each of the four corners of the roof 12. The tops of the upper columns 32 are pivotally connected to the roof 12, while the bottoms of the lower columns 31 are pivotally connected to the base 11. The hinge structure 4 is installed between a corresponding lower column 31 and upper column 32.

[0037] The foldable container house is generally rectangular in shape, with end walls 21 located at the ends of its length. The top of the end wall 21 is swingably mounted to the roof 12 via a second hinge 321. The upward and downward movement of the end wall 21 is controlled by a hydraulic or pneumatic rod. When the foldable container house is in use, the end wall 21 stands upright between the base 11 and the roof 12. A door 211 is mounted on the end wall 21 at the front end of the foldable container house.

[0038] The side wall 22 is composed of a lower wall part 221 and an upper wall part 222 that can move relative to each other, and the opposite ends of the lower wall part 221 are fixedly connected to a corresponding lower column 31, and the opposite ends of the upper wall part 222 are fixedly connected to a corresponding upper column 32.

[0039] Combine Figures 3 to 5 , Figure 3 This is a structural diagram of the hinge structure in the embodiment of the folding container house of the present invention. Figure 4 for Figure 2 The enlarged view of point A in the middle. Figure 5 This is a structural diagram of the lower column, upper column and hinge structure in the embodiment of the folding container house of the present invention. The hinge structure 4 is composed of a first hinge 41 and a second hinge 42 hinged to the rotation axis 40.

[0040] The first hinge 41 comprises a first leaf 411 and a first rotating shaft 43, which are fixed to each other. The second hinge 42 comprises a second leaf 421 and a second rotating shaft 44, which are fixed to each other. The first leaf 411 and the second leaf 421 are hingedly connected via a hinge shaft 49, the axis of which is the rotation axis 40. The first rotating shaft 43 is inserted into the first leaf 411, and the first end of the first rotating shaft 43 extends through the first leaf 411 to form a raised first abutment 431. The first end of the first rotating shaft 43 is provided with a first threaded section 432 (not shown). The second rotating shaft 44 is inserted into the second leaf 421, and the first end of the second rotating shaft 44 extends through the second leaf 421 to form a raised second abutment 441. The second end of the second rotating shaft 44 is provided with a second threaded section 442 (not shown).

[0041] The first rotating shaft 43 and the second rotating shaft 44 are both perpendicular to the rotating axis 40. Figure 4 and Figure 5 As shown, when the hinge structure 4 is in the extended state, the first rotating shaft 43 and the second rotating shaft 44 are coaxial with each other, the first abutting portion 431 and the second abutting portion 441 abut against each other, and the first hinge 41 restricts the second hinge 42 from rotating.

[0042] A first connector 33 is provided inside the top of the lower column 31. The first connector 33 is provided with a first through hole 331 extending along the extension direction of the lower column 31. After the first rotating shaft 43 passes through the first through hole 331 from top to bottom, two first nuts 51 with washers between them are locked with the first threaded segment 432. The first connector 33 is restricted between the first leaf 411 and the first nut 51, and the first rotating shaft 43 maintains the rotational freedom relative to the first connector 33. The first leaf 411 protrudes outside the top of the lower column 31.

[0043] The bottom of the upper column 32 includes a second connector 34. The second connector 34 is positioned higher than the blocking wall 329 at the bottom of the lower column 31. Therefore, a receiving groove 320 surrounded on all sides and open at the bottom is formed between the bottom surface of the second connector 34 and the blocking wall 329. The depth of the receiving groove 320 is greater than the total height of the first leaf 411 and the second leaf 421 of the hinge structure 4 in the extended state. The second connector 34 is provided with a second through hole 341 extending along the extension direction of the upper column 32. After the second rotating shaft 44 passes through the second through hole 341 from bottom to top, two second nuts 52 with washers between them are locked with the second threaded section 442. The second connector 34 is confined between the first leaf 411 and the first nut 51. The second rotating shaft 44 maintains the degree of rotational freedom relative to the second connector 34 and can slide linearly within the limit stroke d relative to the second connector 34. See Figure 4When the folding box house is in use, the lower column 31 and the upper column 32 abut against each other, the first page 411, the second page 421 and the hinge shaft 49 are stored in the storage groove 320, and are blocked and stopped by the blocking wall 329.

[0044] See also Figure 4 When the folding box house is in use, the rotation axis 40 is located at the center of the lower column 31 and the upper column 32 in the horizontal direction. Taking the vertical reference surface 400 where the rotation axis 40 is located as a decomposition, the first abutting portion 431 and the second abutting portion 441 abut against each other on the first side 401 of the vertical reference surface 400, that is, the first side 401 of the rotation axis 40, and the top of the lower column 31 and the bottom of the upper column 32 abut against each other on the second side 402 of the vertical reference surface 400, that is, the second side 402 of the rotation axis 40. At this point, the rotational freedom in the first rotational direction between the first hinge 41 and the second hinge 42 is limited by itself, while the rotational freedom in the second rotational direction is limited by the abutment between the lower column 31 and the upper column 32. Regardless of whether a force is applied to the columns from the first side 401 or the second side 402, the lower column 31 and the upper column 32 cannot move relative to each other, thereby stably maintaining the upright position between the lower column 31 and the upper column 32. The position of the hinge structure 4 at this point is recorded as the second rotational position.

[0045] See also Figure 6 , Figure 6 The following is a schematic diagram of the folding wall structure of an embodiment of a foldable container house according to the present invention. The following describes the folding method for converting a foldable container house from its in-use configuration to its folded configuration. First, the hydraulic rod 29 is controlled to swing the end wall 21 upward. Because a downward-facing storage space 120 is formed in the roof 12, the end wall 21 swings upward to a predetermined position and is stored in the storage space 120.

[0046] Combine Figure 7 , Figure 7 This diagram illustrates the structure of the lower columns, upper columns, and hinge structure of the foldable container house embodiment of the present invention in a transitional configuration. The roof 12 and upper columns 32 of the foldable container house are then lifted. Because the second rotating shaft 44 can slide linearly relative to the second connecting body 34 within a limit travel d, the hinge structure 4 is not lifted when the upper column 32 is lifted. Consequently, the first leaf 411, second leaf 421, and hinge shaft 49 of the hinge structure 4 are exposed outside the receiving groove 320 and positioned within the gap between the upper column 32 and the lower column 31, which is equal to the limit travel d.

[0047] Recombination Figures 8 and 9 , Figure 8 This is a structural diagram of a semi-folded folding container house embodiment of the present invention. Figure 9 for Figure 8An enlarged view of point B in the middle. The first and second leaf pieces 411, 421 are then twisted using a dedicated tool. After the hinge structure 4 rotates 180 degrees, it rotates from the second rotational position to the first rotational position. At this point, the folding container is in a transitional state. The first hinge 41, the second hinge 42, the upper column 32, and the lower column 31 are all located on the second side 402 of the vertical reference plane 400, i.e., on the second side 402 of the rotation axis 40. At this point, the first and second hinges 41, 42 regain their swinging freedom, allowing the upper column 32 and the lower column 31 to bend by force.

[0048] Recombination Figures 8 to 10 , Figure 10 This is a structural diagram of the folding form of the folding container house embodiment of the present invention. Then the lifting device slowly descends, the roof 12 and the upper column 32 descend, and the roof 12, the upper column 32, the lower column 31 and the base 11 swing towards the folding state, and finally the folding container house reaches Figure 10 The folded form shown. At this time, the lower column 31 and the upper column 32 are overlapped, and the upper column 32 is located in the accommodating space 120 ( Figure 6 In addition, combined with Figure 1 Since the lower wall portion 221 is fixed between the two lower columns 31, the upper wall portion 222 is fixed between the two upper columns 32, and the lower wall portion 221 and the upper wall portion 222 are connected by a flexible material or a flexible material so as to be able to swing relative to each other, the lower wall portion 221 and the upper wall portion 222 move relative to each other along with the relative movement between the lower columns 31 and the upper columns 32.

[0049] See in order Figure 10 、 Figure 8 、 Figure 7 、 Figure 4 and Figure 6 The method for transforming the folding container house from the folded form to the usable form is to first lift the roof 12 of the folding container house in the folded form together with the upper column 32, and the upper column 32 and the lower column 31 are located in the same straight line. At this time, the folding container house reaches the transition form, the hinge structure 4 is located in the first rotation position, and the first hinge 41, the second hinge 42, the upper column 32 and the lower column 31 are all located on the second side 402 of the vertical reference surface 400.

[0050] Then, using a dedicated tool, the first leaf 411 and the second leaf 421 are twisted. After the hinge structure 4 rotates 180 degrees, it rotates from the first rotation position to the second rotation position. The hoisting device then slowly descends, and the roof 12 and the upper column 32 are lowered until the upper column 32 and the lower column 31 abut against each other. At this time, the first abutting portion 431 and the second abutting portion 441 abut against the first side 401 of the rotation axis 40, and the top of the lower column 31 and the bottom of the upper column 32 abut against the second side 402 of the rotation axis 40. Finally, the hydraulic rod 29 is controlled to swing the end wall 21 downward and reach the preset position of the base 11 and the roof 12. The foldable container house is successfully transformed into the use configuration. The foldable container house provided by the present invention can be transformed between the use configuration and the folded configuration, thereby facilitating the transportation of the container house. The container house configuration transformation operation is simple, thereby improving assembly efficiency.

[0051] In other embodiments, the angle through which the hinge structure rotates from the first rotation position to the second rotation position can be 90 degrees, 270 degrees or other angles. As long as the hinge structure is in the first rotation position, the first hinge, the second hinge, the upper column and the lower column are all located on the same side of the rotation axis, and when the hinge structure is in the second rotation position, the first abutting portion and the second abutting portion abut against each other on the first side of the rotation axis, and the top of the lower column and the bottom of the upper column abut against each other on the second side of the rotation axis, it should fall within the protection scope of the present application.

[0052] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
