Abstract
Description
Technical Field
[0001] This utility model relates to the field of model unfolding technology, specifically to an unfoldable model device for interior design. Background Technology
[0002] Interior design is the process of creating a functional and aesthetically pleasing interior environment that meets people's material and spiritual needs, based on the building's usage, environment, and relevant standards, using material and technical means and architectural design principles. To facilitate the presentation and display of design results, a house model is usually created based on the design.
[0003] Extensive research revealed that the Chinese Utility Model Patent Publication No. CN221511478U discloses a deployable interior design model device, belonging to the technical field of model devices. This deployable interior design model device includes a base plate; a rotating groove located at the upper end of the base plate; two first sliding grooves, both located at the upper end of the base plate; two second sliding grooves, both located at the upper end of the base plate; and two first L-shaped wall panels, each slidably connected to one of the two first sliding grooves.
[0004] While the above solution offers numerous advantages, it also presents the following drawbacks: The device utilizes L-shaped wall panels to form the model, and the distance between these panels is adjustable, allowing for model size adjustments. However, this adjustment method results in gaps and large gaps between adjacent L-shaped wall panels, which affects the overall aesthetics of the interior design deployable model device. While using fixed plates to fill the gaps is convenient, the fixed plate structure is simple and fixed, thus limiting the width adjustment of the model and reducing the overall practicality of the interior design deployable model device. Utility Model Content

[0012] Preferably, the upper part of the floor is provided with multiple furniture models.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This application uses a center plate and wall covering to fill the gap between two L-plates, thus avoiding gaps in the wall caused by adjusting the size of the model, and effectively improving the overall aesthetics and practicality of the interior design unfoldable model device.
[0015] 2. This application features a detachable floor that can be magnetically attached, allowing for easy adjustment of the number of rectangular panels to accommodate changes in model size. This alters the width of the floor, thereby enhancing the overall aesthetics and practicality of the expandable interior design model device.

[0025] 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.
[0026] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for an interior design deployable model device, including a base plate 1, four L-plates 2 arranged in a circular array slidably connected to the upper part of the base plate 1, the four L-plates 2 forming a square shape, four center plates 3 arranged in a circular array slidably connected to the upper part of the base plate 1, a wall covering 4 sleeved on the outer side of the center plate 3, and grooves 5 opened at both ends of the L-plates 2, the center plates 3 being slidably connected to the cavities of the grooves 5 on the L-plates 2, and two guide rods 6 being rotatably connected at the opening of the grooves 5, the guide rods 6 being located between the inner wall of the wall covering 4 and the outer wall of the center plate 3;
[0027] By pulling two adjacent L-plates 2, the outer diameter of the entire model is expanded. During the pulling of L-plates 2, the center plate 3 between the two L-plates 2 slides in the cavity of the slide groove 5. The wall cloth 4 is parallel to the surface wall of L-plates 2, thus covering the gap between the two L-plates 2, so that the two adjacent L-plates 2 and the wall cloth 4 form a flat wall, thereby improving the aesthetics of the model wall.
[0028] The surface color of wallpaper 4 is the same as the surface color of board 2.
[0029] like Figure 3 and Figure 5 As shown, a through groove 7 is provided on the upper part of the base plate 1. A gear 8 is rotatably connected to the inner wall of the through groove 7. A rack rod 9 distributed in a circular array is meshed around the gear 8. A convex rod is fixedly connected to the edge of the rack rod 9. Adjacent rack rods 9 are staggered vertically. A rod groove 10 distributed in a circular array is provided on the inner wall of the through groove 7. A convex rod adapted to the convex rod is provided on one side of the inner wall of the rod groove 10. Each rack rod 9 is slidably connected in the cavity of each rod groove 10. Each center plate 3 is fixedly connected to the end of each rack rod 9.
[0030] By rotating gear 8, gear 8 drives each rack rod 9 to slide in the corresponding rod groove 10. In this way, the rack rod 9 drives each center plate 3 to move closer to or further away from the axis of gear 8, thereby adjusting the width of the model or wall panel.
[0031] like Figure 3 As shown, a motor 11 is mounted on the base plate 1. The output end of the motor 11 is fixedly connected to the shaft of the gear 8. The motor 11 is electrically connected to the power supply.

[0034] The floor 12 is composed of multiple smaller rectangular plates, and the number of rectangular plates can be increased according to the size of the model, thus making it easy to adjust the width of the floor 12. The rectangular plates are made of metal as a whole, or metal material that can be attracted by magnets 13 can be added inside them.
[0035] like Figure 3 , Figure 5 and Figure 6 As shown, multiple grooves are provided on the upper part of the base plate 1 and the gear 8, and magnets 13 are installed in the grooves;
[0036] The floor 12 is magnetic and can be attached to the surface of the base plate 1 using magnet 13, thus improving the ease of installation of the floor 12.
[0037] like Figure 6 As shown, a protruding rod 15 is fixedly connected to one side of the rectangular plate, and a protruding groove 14 adapted to the protruding rod 15 is opened on the other side of the rectangular plate.
[0038] By inserting the protruding rod 15 in one of the rectangular plates into the cavity of the protruding groove 14 in the adjacent rectangular plates, the rectangular plates are combined into a whole floor 12, thereby improving the stability and convenience of assembling the floor 12.
[0039] like Figure 6 As shown, multiple furniture models 16 are installed on the upper part of the floor 12;
[0040] The specific related structures of furniture model 16, as well as the connection methods and usage methods of the related structures, are all existing technologies. For a detailed description, please refer to the corresponding structures and components in the unfoldable interior design model device published in CN221511478U. This application will not elaborate further.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
