Description

Technical Field

[0001] This utility model relates to the field of building decoration materials and door manufacturing technology, specifically to a lightweight artificial stone door. Background Technology

[0002] In the door manufacturing industry, traditional artificial stone doors have revealed numerous problems in practical applications. From a material perspective, wooden doors contain formaldehyde and are prone to mold; aluminum doors are susceptible to paint peeling and rust; stainless steel doors have a cold color and lack appeal; and plastic doors are prone to aging and damage. Regarding the manufacturing process of artificial stone doors, sandwich structures with aluminum, plastic, or paper honeycomb cores are not only costly and time-consuming to produce, but also negatively impact door performance. Structures with horizontal and vertical artificial stone strips sandwiched in the middle result in excessive weight, making them prone to deformation and causing inconvenience during installation and use. Artificial stone doors made from single 12mm thick slabs have significant size limitations, are heavy, and expensive. Furthermore, all traditional artificial stone door panels are essentially limited to a flat surface, unable to create rich textures and patterns, failing to meet consumers' demands for aesthetics, practicality, and personalization. Therefore, improvements are needed. Utility Model Content

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meanings of the above-mentioned components within this utility model according to the specific circumstances.

[0027] In some embodiments of this utility model, a support frame 1, an artificial stone panel 2, and connecting components are included. The artificial stone panel 2 is installed inside the support frame 1, and the connecting components are installed on the support frame 1. The thickness of the thin artificial stone panel 2 is 4-6mm.

[0028] Specifically, the lightweight artificial stone door mainly consists of a support frame 1, an artificial stone panel 2, and connecting components. The artificial stone panel 2 is installed inside the support frame 1, and the two fit together tightly to form the main barrier part of the door. The connecting components are installed on the support frame 1 and are the key components for realizing the opening and closing function of the door. The artificial stone panel 2 has a thin structure, with its thickness precisely controlled between 4-6mm. The support frame 1, as the skeleton of the door, provides a stable support foundation for the artificial stone panel 2, allowing it to maintain a fixed shape and position. The connecting components connect the support frame 1 to the door frame or other fixed structures, and through their own movable characteristics, enable the door to rotate around an axis, completing the opening and closing action. The thin artificial stone panel 2, while ensuring the basic functions of the door, effectively reduces the overall weight of the door due to its thinness.

[0029] In some embodiments of this utility model, the support frame 1 is made of artificial stone material, and the interior of the support frame 1 has a reinforcing rib structure with the reinforcing ribs distributed in a grid pattern.

[0030] Specifically, the support frame 1 is made of artificial stone, with internal reinforcing ribs distributed in a grid pattern and integrally formed with the main frame body. These reinforcing ribs are tightly connected to all parts of the frame, enhancing the overall structural strength. The grid-like distribution of the reinforcing ribs effectively disperses external forces on the support frame 1 by increasing structural complexity and stability. When the door is subjected to impact or compression, the reinforcing ribs can evenly distribute the force throughout the entire frame, preventing localized stress concentration that could lead to frame deformation. This design significantly improves the rigidity and load-bearing capacity of the support frame 1, making the door more stable and reliable during long-term use, less prone to deformation, and extending the door's service life.

[0031] In some embodiments of this utility model, the surface of the artificial stone panel 2 has a textured surface, which is integrally formed by a hot press mold, and the depth of the textured surface is 0.5-2mm.

[0032] Specifically, the textured surface of the artificial stone panel 2 is integrally formed using a hot-press mold, tightly bonded to the panel itself, becoming an inseparable part of the panel. During the manufacturing process of the artificial stone panel 2, the prepared artificial stone material is placed into a hot-press mold with a specific texture. Under high temperature and pressure, the material fills the mold's texture and solidifies, thus forming a textured surface on the panel. This design greatly enriches the door's appearance, increases the three-dimensionality and tactile feel of the door panel, enhances its decorative and artistic qualities, satisfies consumers' pursuit of personalization and aesthetics, and allows the door to better integrate into different decorating styles.

[0033] In some embodiments of this utility model, the connecting component is a foldable hinge, which includes multiple movable pieces that are hinged to each other, and a damping device is provided between the movable pieces.

[0034] Specifically, the connecting components employ a foldable hinge, which comprises multiple interlocking movable pieces, with a damping device installed between them. One end of the hinge is fixed to the support frame 1, and the other end is connected to the door frame or other fixed structure. When the door needs to be opened or closed, the interlocking movable pieces rotate around the hinge point under the action of force, realizing the opening and closing action of the door. The damping device provides resistance to slow down the rotation speed of the movable pieces, preventing the door from colliding and making noise due to excessive speed during opening and closing. This design makes the opening and closing of the door more flexible and smooth, while the presence of the damping device effectively reduces the impact force and noise when the door is opened and closed, improving the user experience and extending the service life of the door and connecting components.

[0035] Fabrication of Support Frame 1: Artificial stone material is selected. The artificial stone material is cut according to the design dimensions, ensuring a cutting accuracy within ±0.5mm. Reinforcing ribs are fabricated inside the artificial stone material using mold casting or machining. The height of the reinforcing ribs is 5-8mm, and the width is 3-5mm. The grid spacing is rationally designed according to the frame size and stress conditions, generally 20-30mm. The processed artificial stone material is formed into the basic shape of support frame 1 through an integrated molding process. High-precision molds are required during fabrication to ensure the dimensional accuracy and quality stability of the frame. The four corners of support frame 1 are integrally molded using die casting or injection molding processes to create an arc-shaped transition at the corners, with the transition radius controlled between 10-20mm.

[0036] Figures 3 to 8 The supporting frame 1 exhibits a rich variety of design features to meet different functional requirements and application scenarios. In terms of overall shape, it encompasses both regular geometric shapes and unique irregular designs. Among them, Figure 3 and Figure 4 It is a rectangular frame. Figure 3 As a basic rectangular frame, it is simple and practical, and suitable for most common installation environments; Figure 4 Based on this, a 10mm wide outward-protruding decorative strip was added to the top and bottom edges, enhancing the aesthetics and creating a sense of depth, making it more suitable for places with certain decorative requirements. Figure 5 The irregular polygonal frame is tailored to specific use cases and can better adapt to irregular spaces or special architectural structural requirements. Figure 7 The irregularly shaped frame combines curves and broken lines, creating a unique design that offers options for projects seeking personalized designs. Figure 8 The modular frame is composed of multiple components of different shapes. This innovative design not only gives the door a unique appearance but also allows for flexible component combinations to meet diverse functional needs. Furthermore, the inner side of the frame is mostly equipped with slots 11 with a depth of 5-8mm. These slots 11 are specifically designed to fit the edges of 4-6mm thick artificial stone panels 2, ensuring that the artificial stone panels 2 can be securely embedded, achieving an organic combination of structure and decoration. Figure 6 The sectional view reveals the complex and ingenious structure of a portion of the support frame 1. Horizontally, the leftmost protruding part of this structure is 5mm wide, with an overall horizontal length of approximately 18mm from left to right, including a 7mm section. Vertically, the overall height is 20mm, with a small 2mm structure on the right side. This precise dimensional arrangement and the way it connects with other components achieve the function of the support frame 1, further demonstrating the scientific and rigorous nature of the design.

[0037] Preparation of Artificial Stone Panel 2: Prepare artificial stone raw materials, adding pigments, fillers, and curing agents in a certain proportion. Thoroughly mix the raw materials to form an artificial stone blank. Place the artificial stone blank into a hot-press mold with a textured surface, the texture depth of which is 0.5-2mm. During the hot-pressing process, control the temperature at 120-150℃, the pressure at 5-8MPa, and the holding time at 10-15 minutes to allow the blank to solidify and form the artificial stone panel 2 with a textured surface. Perform post-treatments such as grinding and polishing on the formed artificial stone panel 2 to remove surface imperfections and burrs, improving the surface quality and gloss. During grinding, use sandpaper of different grits for gradual grinding, and finally polish with polishing wax.

[0038] Installation of connecting components: Install the fixed part of the foldable hinge onto the support frame 1, securing it using bolts or welding. When bolting, ensure the tightening torque is within the specified range, generally 8-12 N·m; when welding, ensure welding quality, avoiding incomplete or missed welds. Connect the moving part of the hinge to the door frame or other fixed structure. During installation, pay attention to adjusting the hinge's position and angle to ensure the door can open and close normally, with an opening angle generally between 90° and 180°. Install damping devices, such as damping washers or damping springs, between the moving parts of the hinge. Damping washers can be made of rubber or silicone, with a thickness of 2-3 mm; the spring constant of the damping spring is selected based on the weight of the door and usage requirements, generally 5-10 N / mm.

[0039] Overall Assembly: Embed the artificial stone panel 2 into the slot 11 of the supporting frame 1, ensuring a tight fit between the panel and the frame. The depth of the slot 11 should be 5-8mm. During the embedding process, tools such as a rubber mallet can be used to gently tap the panel to ensure it is fully embedded in the slot 11. Perform an overall inspection of the assembled door, checking for smooth opening and closing, good sealing performance, and any deformation of the frame. If any problems are found, adjust and repair them promptly. Install decorative strips or other accessories on the door surface to enhance its aesthetics and practicality. Decorative strips can be made of metal, plastic, or wood, selected according to the door's design style.

[0041] This structural design fundamentally solves the problem of the heavy weight of traditional artificial stone doors, significantly reducing the weight of the door and making it easier to transport, install, and use daily. At the same time, the use of thin artificial stone panels 2 also lays the foundation for further enriching door designs and reducing costs.

[0042] The above are merely the principles and preferred embodiments of this utility model.
