Description

Technical Field

[0001] This invention belongs to the field of container technology, and specifically relates to a foldable house container. Background Technology

[0002] With the promotion of industrialized construction, modular housing containers are gaining widespread application due to their advantages such as standardized factory production, on-site assembly construction, minimal impact from weather, and reusability. However, existing housing containers mostly employ fixed container structures, which cannot be compressed and stored, resulting in limited transport capacity per vehicle and high logistics costs. While existing folding containers offer folding capabilities, their standalone design prevents them from being extended and connected with other containers, hindering economies of scale and limiting their application scenarios and flexibility. Therefore, how to improve the expandability and ease of installation of housing containers while ensuring the structural strength of shipping containers, and simultaneously reduce transportation and logistics costs, is a problem that needs to be solved in this field. Summary of the Invention

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a foldable housing container. This invention can solve the technical problems of high transportation costs and poor expandability of existing housing containers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] This invention provides a foldable house container, characterized in that it includes a base frame, with a front end and a rear end fixedly connected to the front and rear ends of the base frame respectively, and a top end fixedly connected to the top of the front end and the rear end. A flip-up base frame is rotatably connected to both sides of the base frame via piano key hinges, and a flip-up end is rotatably connected to the front end or the rear end via a piano key hinge. A false corner piece is provided on the outer side of the flip-up end, and the false corner piece is provided with an external connection hole structure. The flip-up base frame and the flip-up end can be flipped relative to each other, so that the container can be converted between a folded state and an unfolded state.

[0006] Furthermore, the flipping end includes a top end beam and a bottom end beam, which are connected by the false corner piece. The width of the false corner piece is the same as that of the top end beam. A nut is pre-embedded inside the false corner piece. In the unfolded state, it is fastened to the end corner piece set on the front or rear end by connecting angle iron.

[0007] Furthermore, the top beam of the flipped end is equipped with a pre-embedded threaded sleeve and a special support, which are used to lock the flipped end in the folded state onto the reserved waist hole of the top side beam fixed to the top side.

[0008] Furthermore, the lower crossbeam of the flip end has a pre-drilled mounting hole and a pre-embedded sleeve. In the unfolded state, the flip end is rigidly fixed to the flip base frame by bolts.

[0009] Furthermore, both the front end and the rear end include a fixed outer corner post, a fixed first inner corner post, and a fixed second inner corner post. The fixed outer corner post is the outer main load-bearing component, with its upper and lower ends welded and fixed to the top and bottom corner pieces of the front end and the rear end, respectively. One side of the fixed outer corner post is aligned with the inner side of the corner piece, and the other side extends beyond the corner piece, forming the outer frame of the post. The fixed first inner corner post is located at the lateral center of the fixed outer corner post. One side of the fixed second inner corner post is flush with the inner wall of the fixed outer corner post aligned with the corner piece, forming a double-layer reinforcement structure. The fixed outer corner post is equipped with a fixed outer corner post corresponding to the fixed inner corner post. A pre-drilled hole is provided at the position of the second inner corner post. A fixing threaded sleeve is placed in the gap between the fixed second inner corner post and the fixed outer corner post, and welded to both. The flipping end includes an end outer corner post, an end first inner corner post, and an end second inner corner post. The arrangement relationship between the end outer corner post, the end first inner corner post, and the end second inner corner post is the same as the arrangement relationship between the fixed outer corner post, the fixed first inner corner post, and the fixed second inner corner post. The end second inner corner post is hinged to the fixed second inner corner post through the piano key hinge, serving as the movable base point for the rotation of the flipping end.

[0010] Furthermore, in the folded state, the positioning holes on the end beam of the flip-up base frame are locked to the fixing threaded sleeve by bolts to fix the flip-up base frame to the front end or the rear end.

[0011] Furthermore, the flip-up base frame includes a bottom side beam, the corner pieces of the base frame are embedded inside the bottom side beam, the flip-up base frame also includes the end bottom beams disposed at both ends thereon, forming a closed and stable frame with the bottom side beam, and the bottom side beam is used to weld the piano key hinge.

[0012] Furthermore, a sealing strip is provided on the surface of the bottom side beam.

[0013] Furthermore, the top end is constructed of a flat, reinforced top plate, and a notch is provided at the top end as a reserved opening for connecting to the upper staircase or elevator.

[0014] Furthermore, the key hinge has a concealed layout, which allows the flip base to be precisely aligned with the outer surface of the base and the flip end with the outer surface of the front or rear end when fully unfolded.

[0015] The beneficial effects of the present invention.

[0016] This invention meets the standard requirements for land transportation. It employs a piano-key hinge connection, ensuring smooth flipping action, precise alignment of the outer surfaces, and a high level of aesthetics. The flipping end features a false corner design with retained external connection holes, ensuring both compact overall thickness during folding, significantly saving transportation and storage space, and expandable connectivity after unfolding, allowing for economies of scale when combined with other containers. Pre-embedded threaded sleeves on the top end beam and pre-embedded sleeves on the bottom end beam ensure a secure connection of all components in both folded and unfolded states, resulting in strong structural stability. Fixed threaded sleeves are welded to the gaps between the fixed outer corner posts and the fixed second inner corner posts. In the folded state, the flipping base is bolted in place via positioning holes to prevent loosening and ensure transportation safety. Sealing strips are installed on the bottom side beam surface and end surfaces, forming a reliable seal at the splicing points during unfolding, ensuring waterproof and seepage-proof performance. The overall operation is simple, highly safe, and allows for quick assembly and disassembly. Folding significantly reduces the container size, effectively lowering transportation costs, while unfolding allows for greater space utilization. Attached Figure Description

Detailed Implementation

[0030] As shown in the accompanying drawings, this embodiment provides a foldable house container, including a base frame 100. A front end 300 and a rear end 400 are fixedly connected to the front and rear ends of the base frame 100, respectively. A top end 600 is fixedly connected to the top of the front end 300 and the rear end 400. A flip-up base frame 200 is rotatably connected to both sides of the base frame 100 via piano-key hinges 700. A flip-up end 500 is rotatably connected to either the front end 300 or the rear end 400 via piano-key hinges 700. A false corner piece 540 is provided on the outer side of the flip-up end 500, and the false corner piece 540 has external connection holes for extended connection with other containers or components. The overall main frame uses a combination of channel steel and bent corner posts, ensuring overall load-bearing capacity and structural strength.

[0031] Through the above connection, the flipping base 200 and the flipping end 500 can flip relative to the base 100 and the front end 300 or the rear end 400, thereby allowing the entire container to switch between a folded state and an unfolded state.

[0032] The flip-up end 500 includes a top end beam 510 and a bottom end beam 520, connected by a false corner piece 540. The width of the false corner piece 540 is the same as that of the top end beam 510, strictly controlling the overall thickness in the folded state, making the box structure compact after folding and saving transportation and storage space. In the unfolded state, the false corner piece 540 is securely connected to the end corner piece 310 located on the front end 300 or rear end 400 through its internally embedded nuts and connecting angle irons 550, effectively improving the installation stability of the flip-up end 500. In the unfolded state, the surface of the false corner piece 540 is provided with a sealing strip 800 to ensure that the end is flush with the front and rear end faces and the splicing is tight.

[0033] To ensure that all components are securely fixed in both folded and unfolded states, the top beam 510 of the flip end 500 is equipped with a pre-embedded threaded sleeve and a special support 511. In the folded state, the special support 511 can firmly lock the flip end onto the reserved waist hole 611 of the top side beam 610 fixed to the side of the top end 600, preventing the components from shaking or shifting during transportation. At the same time, the lower crossbeam 520 of the flip end 500 has reserved mounting holes and a built-in pre-embedded sleeve 530. In the unfolded state, the flip end 500 can be rigidly fixed to the flip base frame 200 by bolt tightening, comprehensively enhancing the overall stability of the box.

[0034] To enhance the compressive load-bearing capacity of the columns, the front end 300 and rear end 400 have been upgraded based on the standard structure: the fixed outer corner column 320 is the outer main load-bearing component, with its upper and lower ends welded and fixed to the top and bottom corner pieces respectively. One side of it is aligned with the inner side of the corner piece, and the other side extends beyond the corner piece, forming the outer frame of the column; the fixed first inner corner column 330 is located at the horizontal center of the fixed outer corner column 320; one side of the fixed second inner corner column 340 is flush with the inner wall of the fixed outer corner column 320 aligned with the corner piece, forming a double-layer reinforced structure; a reserved hole is opened on the fixed outer corner column 320 corresponding to the position of the fixed second inner corner column 340, and the fixed threaded sleeve 350 is placed in the gap between the fixed second inner corner column 340 and the fixed outer corner column 320 and welded and fixed to both, realizing the threaded connection function for accessory installation.

[0035] The flip end 500 adopts the same column structure as the front end 300 and the rear end 400, namely, it includes an outer corner post 560, a first inner corner post 570, and a second inner corner post 580. The arrangement relationship between the three is the same as that between the fixed outer corner post 320, the fixed first inner corner post 330, and the fixed second inner corner post 340, but without threaded sleeves. Among them, the second inner corner post 580 is hinged to the fixed second inner corner post 340 through a piano key hinge 700, serving as the movable base point for the rotation of the flip end 500.

[0036] In the folded state, the flip-up base frame 200 is bolted to the fixing threaded sleeve 350 via the positioning holes 221 on its end bottom beam 220, thus ensuring reliable fixation of the flip-up base frame 200 in the folded state. This prevents loosening and deformation after long-term use, improving safety and durability. When unfolding, the connecting bolts must be removed before lowering the flip-up base frame 200.

[0037] For the flip-up base frame 200, its bottom side beam 210 is designed to be elongated, allowing the corner pieces of the base frame 100 to be nested inside the bottom side beam 210. End beams 220 are added to both ends of the flip-up base frame 200, forming a closed and stable frame together with the bottom side beam 210. The bottom side beam 210 is used to weld the piano key hinges 700, enabling flexible rotation. After the cabinet is unfolded, the flip-up base frame 200 can serve as a load-bearing support component for the flip-up end 500, effectively improving material utilization and space practicality.

[0038] The top 600 abandons the traditional curved top plate and adopts a flat, ribbed top plate, maximizing the internal usable space of the enclosure while ensuring structural strength. The top 600 has a notch 620, which serves as a reserved opening for connecting to the upper-level stairs or elevator to accommodate modular assembly requirements.

[0039] As key to achieving smooth folding action and excellent appearance, the piano key hinge 700 adopts a concealed layout. This allows for precise alignment of the outer surfaces of the flip base 200 and base 100, as well as the outer surfaces of the flip end 500 and the front end 300 or rear end 400 when fully unfolded, resulting in a neat and uniform overall appearance of the case.

[0040] The standard deployment procedure for this container house is as follows: First, apply sealing strip 800 to the surface of the bottom beam 210, ensuring that the application is flat, firm, wrinkle-free, and bubble-free, thus creating a waterproof and seepage-proof foundation.

[0041] Subsequently, the connecting bolts at the positioning hole 221 on the end bottom beam 220 of the tilting base 200 and the fixing threaded sleeve 350 are removed, and the tilting base 200 is slowly and steadily lowered more than 90°, leaving sufficient working space.

[0042] Next, remove the fixing bolts of the flip end 500, attach the sealing strip 800 to the surface of the false corner piece 540, and flip it outward to adjust it so that it is flush with the end face of the front end 300 or the rear end 400 and the splicing is tight.

[0043] Next, install and lock the connecting angle iron 550 at the false corner piece 540 to enhance the stability of the end splicing structure; then reset and fully lock the flip base frame 200 with bolts to prevent shaking and displacement.

[0044] Finally, polyurethane foam material is sprayed into the gaps of the bottom side beams to fill the gaps and improve the heat insulation, sound insulation and seepage prevention performance of the enclosure; the leveling and sealing groove is installed and precisely adjusted to ensure that the internal ground is flat and meets the standards for daily use.

[0045] When folding and storing, simply reverse the steps described above: First, remove the locking bolts between the unfolded state of the flip-up base frame 200 and the flip-up end 500. Flip the flip-up base frame 200 upwards to reset it, then flip the flip-up end 500 inwards. Lock the flip-up end 500 into the reserved waist hole 611 of the top side beam 610 using the special support 511 on the end top beam 510. Finally, secure it with bolts through the positioning hole 221 on the end bottom beam 220 and the fixing threaded sleeve 350 to achieve reliable fixation in the folded state. The size of the box is significantly reduced after folding, meeting the requirements of land transportation standards and significantly reducing transportation and storage costs.

[0046] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
