Description

Technical Field

[0001] This utility model relates to the field of extended house technology, specifically a small-extension, large-slope extended house structure. Background Technology

[0002] Container houses are a type of movable and reusable building product, also known as "modular container houses" or "container houses." They are modular building products that are movable and reusable, using a steel frame structure and bolted connections. They are constructed by combining standardized container units. Based on their structure, they can be divided into three categories: traditional container converted container houses, newly welded container houses, and detachable container houses.

[0003] Most retractable extension houses on the market are built by extending small modules from the main structure. The extended exterior walls and floors are blocked by beams. When the small modules are closed or opened, they will affect the interior decoration of the main structure. After the small modules are extended, the location of the large structure to accommodate the small structures still requires on-site decoration measures to complete the overall decoration effect. They are not convenient and flexible in use.

[0004] Therefore, this utility model provides a small-extension, large-slope double-slope extended house structure to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This utility model provides a small-diameter, large-diameter, double-slope extended house structure, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a fixed base plate, with a main structure fixedly connected to the top of the fixed base plate, and an extension component rotatably connected to the outside of the fixed base plate; the extension component includes a flip-up frame, which is rotatably connected to the outside of the fixed base plate; slide rails are fitted onto the inner and outer walls of both the fixed base plate and the flip-up frame; four pulleys are slidably connected inside the slide rails; an extension structure is provided on the top of each of the four pulleys; and a locking structure is provided on the outside of the right-side slide rail. During use, the expansion components work together to expand the room's area. The locking structure allows for quick and easy storage and confinement. The expansion method is simple and fast, featuring a double-slope design for a pleasing appearance and easy drainage. The pre-expansion width is less than or equal to 3.5 meters, facilitating land and sea transport and reducing costs by half. After expansion, the external envelope (roof, exterior walls, doors and windows) and interior decoration (walls, floors, ceilings, custom cabinets, plumbing and electrical systems) are prefabricated, significantly reducing local labor costs and time. During use, the fixed base and main structure are held in place, and the tilting frame is lowered to the ground using a manual hoist or forklift. The expansion structure is then manually pushed out to complete the space expansion. A rain sensor is installed at the joint between the main structure and the pull-out roof structure. When heavy rain is detected, the electric awning automatically opens to prevent backflow and avoids leakage due to prolonged heavy rain and sun exposure, thus improving protection.

[0009] As a preferred technical solution of this application, the flip-up base and the fixed base plate are externally fixedly connected by multiple hinges. The multiple hinges allow the flip-up base to be flipped horizontally when the expansion structure is expanded, and to be flipped vertically when the expansion structure is stored, so as to adapt to the expansion and storage of the expansion structure.

[0010] As a preferred technical solution of this application, the expansion structure is sleeved on the outside of the main structure, and multiple reinforcing ribs are fixedly connected inside the expansion structure. By sleeved on the outside of the main body, the expansion structure can be extended without affecting the interior of the main structure.

[0011] As a preferred technical solution of this application, the locking structure includes multiple connecting pieces, each of which is rotatably connected to the outside of the slide rail. Each of the multiple connecting pieces is provided with a locking bolt inside. The connecting pieces can be rotated and adjusted along the outside of the slide rail to adjust the locking position of the locking bolt.

[0012] As a preferred technical solution of this application, multiple mounting holes are provided on both outer walls of the expansion structure, and the locking bolt can be threaded into the interior of the mounting hole, so that the expansion structure can be locked and limited when it is stored.

[0013] As a preferred technical solution of this application, the extension structure is externally mounted with a mounting base and an electric awning. A rain sensor is fixedly connected to the outside of the mounting base. The rain sensor can easily detect the current rainfall status. When heavy rain is detected, the electric awning automatically opens to prevent rainwater from flowing back in and to avoid the waterproof strip from failing and leaking due to prolonged heavy rain and sun exposure, thereby improving protection.

[0014] (III) Beneficial Effects

[0015] During use, the expansion components work together to expand the house area. The locking structure allows for quick and easy storage and limiting. The expansion method is simple and fast. It features a double-slope design, a good appearance, and easy drainage. The width before expansion is less than or equal to 3.5 meters, which is beneficial for land and sea transportation, directly reducing the cost by half. After expansion, the external envelope, roof, exterior walls, doors and windows, interior decoration walls, floors and ceilings, custom cabinets, water and electricity are all prefabricated, greatly reducing local labor costs and time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a small-extension, large-slope double-slope extended house structure, such as... Figure 1-5 As shown, the small-extension, large-slope extended house structure includes: a fixed base plate 1, a main structure 2 fixedly connected to the top of the fixed base plate 1, and an extension component rotatably connected to the outside of the fixed base plate 1; the extension component includes a flip-up base frame 3, which is rotatably connected to the outside of the fixed base plate 1, and slide rails 5 are fitted to the outer walls of both the inner and outer sides of the fixed base plate 1 and the flip-up base frame 3. Four pulleys 8 are slidably connected inside the slide rails 5, and an extension structure 4 is provided on the top of the four pulleys 8. A locking structure is provided on the outside of the right slide rail 5. During use, the expansion components work together to expand the house area. The locking structure allows for quick and easy storage and limiting. The expansion method is simple and quick, with a built-in double-slope design that looks good and facilitates drainage. The width before expansion is less than or equal to 3.5 meters, which is beneficial for land and sea transportation, directly reducing costs by half. After expansion, the external envelope (roof, exterior walls, doors and windows) and interior decoration (walls, floors, ceilings, custom cabinets, water and electricity) are all prefabricated, greatly reducing local labor costs and cycle time. When in use, the fixed base plate 1 and the main structure 2 are fixed in place and placed in a suitable position. Then, the flipping base frame 3 is flipped down to the ground using a manual hoist or forklift. The expansion structure 4 is then pushed out manually to complete the space expansion operation. A rain sensor 11 is installed at the joint between the main structure and the pull-out roof structure. When heavy rain is detected, the electric canopy 9 automatically opens to prevent rainwater backflow and avoid leakage caused by prolonged heavy rain and sun exposure, thus improving protection.

[0025] The flip-up base frame 3 and the fixed base plate 1 are jointly connected by multiple hinges 6. The multiple hinges 6 allow the flip-up base frame 3 to flip and be placed horizontally when the expansion structure 4 is extended. When the expansion structure 4 is stored, the flip-up base frame 3 is flipped vertically to accommodate the extension and storage of the expansion structure 4. The expansion structure 4 is fitted onto the outside of the main structure 2. The inside of the expansion structure 4 is fixedly connected with multiple reinforcing ribs 7. By fitting the expansion structure 4 onto the outside of the main structure 2, the expansion structure 4 will not affect the inside of the main structure 2 when it is extended.

[0026] The locking structure includes multiple connecting pieces 12, which are rotatably connected to the outside of the slide rail 5. Each connecting piece 12 has a locking bolt 13 inside. The connecting pieces 12 can be rotated and adjusted along the outside of the slide rail 5 to adjust the locking position of the locking bolt 13. Multiple mounting holes 14 are provided on both outer walls of the expansion structure 4. The locking bolt 13 can be threaded into the inside of the mounting hole 14 to lock and limit the expansion structure 4 when it is stored.

[0027] The extension structure 4 is externally mounted with a mounting base 10 and an electric awning 9. A rain sensor 11 is fixedly connected to the outside of the mounting base 10. The rain sensor 11 can easily detect the current rainfall status. When heavy rain is detected, the electric awning 9 automatically opens to prevent rainwater from flowing back in and to avoid the waterproof sealant from failing and leaking due to prolonged heavy rain and sun exposure, thus improving protection.

[0028] When using this type of small-pull-out double-slope expandable house structure, the fixed base plate 1 and the main structure 2 are kept in place and placed in a suitable position. Then, the flipping base frame 3 is flipped down to the ground using a manual hoist or forklift. The expandable structure 4 is then manually pushed out to complete the space expansion operation. A rain sensor 11 is installed at the joint between the main structure and the pull-out roof structure. When heavy rain is detected, the electric canopy 9 automatically opens to prevent rainwater backflow and avoid the waterproof sealant from failing and leaking due to prolonged heavy rain and sun exposure, thus improving protection.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
