Description

Technical Field

[0001] This utility model relates to a melamine decorative door, belonging to the field of furniture panels. Background Technology

[0002] Melamine, chemically known as melamine-formaldehyde resin, is a synthetic thermosetting engineering plastic, often simply referred to as "melamine resin" in the industry. Compared to general-purpose plastics such as PP and PE, melamine possesses significant advantages such as high temperature resistance, flame retardancy, high hardness, and scratch resistance, making it a promising material for furniture panels.

[0003] However, plastic materials generally have inherent defects. Even high-performance melamine resin has shear strength and rigidity far lower than metal. If ordinary metal fasteners are used to lock the melamine door panel directly, local stress concentration is very likely to occur at the fixing position, leading to cracking of the door panel. In scenarios such as cabinet doors that require repeated opening and closing and long-term stress, melamine material will undergo slow plastic deformation, also known as creep. Relying solely on the material itself for connection will gradually loosen and fail over time, seriously affecting the product's lifespan.

[0004] Currently, there are melamine board doors, and there are two main methods for fixing melamine boards: one is to use a metal frame to hold and fix the plastic door panel, and the other is to combine the plastic door panel with a metal door panel. Although both methods improve the connection strength to some extent, they both suffer from high costs and complex manufacturing processes.

[0005] Therefore, this utility model provides a melamine decorative door with a combination of plastic and partial metal materials. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a melamine decorative door that combines plastic with partial metal materials.

[0007] This utility model is implemented as follows: A melamine decorative door includes a door panel, a fixing plate, and a pin. The fixing plate is embedded at both ends of the edge of one end face of the door panel, and the pins are embedded on the door panels on both sides of the fixing plate. The pins and the fixing plate are both made of metal.

[0008] As a further improvement, a first groove and a second groove are formed on one end face of the door panel, and the fixing plate and the pin correspond to the shape of the first groove and the second groove, and the fixing plate and the pin are respectively embedded in the first groove and the second groove.

[0009] As a further improvement, the door panel, fixing plate, and pin are integrally molded using a mold.

[0010] As a further improvement, the door panel has several observation windows.

[0011] As a further improvement, the observation windows are arranged in an array or symmetrically.

[0012] As a further improvement, a third groove is provided on the door panel along the edge of the observation window, in which a window pane is detachably and fixedly connected.

[0013] As a further improvement, the window slat is made of plastic material.

[0014] As a further improvement, the depth h1 of the first groove and the second groove is less than the thickness h2 of the door panel.

[0015] As a further improvement, the pin is a column with threads engraved on its inner surface.

[0016] The beneficial effects of this utility model are as follows: By embedding a metal fixing plate and a pin at the key connection position of the door panel, this utility model utilizes the high strength and high stability characteristics of metal components to effectively transfer the force of the door panel to the metal parts, completely solving the problem of local stress concentration cracking caused by the low shear strength of melamine material. At the same time, it avoids the connection loosening failure caused by creep of plastic under long-term stress, significantly improving the connection stability and service life of the door.

[0017] The door panel of this utility model is made of melamine resin material, and metal material is used only in key connection parts. Compared with the traditional all-metal frame fixing or plastic-metal composite structure, the amount of metal material used is greatly reduced, and the raw material cost is reduced. At the same time, the door panel and metal components are integrally molded, which eliminates complicated subsequent assembly steps, simplifies the production process, improves production efficiency, and is conducive to large-scale production. The observation window on the door panel of this utility model meets the user needs of observing the indoor status without opening the door, and is especially suitable for special scenarios such as clean rooms. The plastic window is removable and replaceable, making maintenance convenient. The metal components are embedded in the groove of the door panel and are not exposed on the surface of the door panel, ensuring the flatness and decoration of the door appearance. Moreover, the observation window can be flexibly arranged in an array or symmetrically to adapt to different decoration needs. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Reference Figures 1-6 As shown, this embodiment provides a specific implementation of a melamine decorative door, including a door panel 10, a fixing plate 20, and a latch 30. The door panel 10 is the main structural component of the melamine decorative door, integrally molded from melamine resin material. It is the core component for realizing the decorative and basic protective functions of the door, playing a core role in separating space and decorating the environment. At the same time, it provides the installation base for components such as the fixing plate, latch, and observation window. Its inherent high temperature resistance, flame retardancy, and scratch resistance ensure the performance of the door. The door panel 10 has a fixing plate 20 embedded at both ends of the edge of one end face. The fixing plate 20 is a block component made of high-strength metal material. During the connection between the door panel 10 and the door frame or the assembly of the door panel itself, the fixing plate 20 disperses the force at the connection point, avoids local stress concentration that could cause the door panel to crack, and provides support for the overall positioning of the door panel 10. The door panels 10 on both sides of the fixing plate 20 are fitted with pins 30. The pins 30 cooperate with external fasteners to achieve fixation. They are the core components for the door panels to achieve movable connection and locking functions. The external fasteners include, but are not limited to, hinges. They are adapted to and connected with hinges, door locks and other components through threaded structure to transfer the force of the door panel to the metal components, effectively avoiding the loosening of the connection caused by creep of the melamine material. At the same time, they realize the opening and closing function of the door and improve the durability of the connection. Both the pins 30 and the fixing plate 20 are made of metal materials.

[0029] The pin 30 is a column with threads engraved on its inner surface, including but not limited to cylindrical and polygonal columns, such as regular hexagonal columns and regular octagonal columns. The threaded structure on the inner surface of the pin 30 can be precisely matched with metal parts such as hinges and door locks, realizing a stable connection between the melamine door panel and the metal connector, breaking through the limitations of single material connection, and expanding the application scenarios of melamine decorative doors.

[0030] In this embodiment, the door panel 10 has several observation windows 40 to realize the visualization function of the door, which is common in scenarios where it is necessary to observe the internal state. The observation windows 40 are arranged in an array or symmetrically, depending on the actual use requirements. The edges of the observation windows 40 are kept at a certain distance from the edges of the door panel to avoid affecting the structural strength of the door panel.

[0031] In other embodiments, the observation window 40 can be used in conjunction with the window slat 50. A third groove 103 is provided on the door panel 10 along the edge of the observation window 40. The window slat 50 is detachably and fixedly connected in the third groove 103. The window slat 50 is a sheet-like component made of plastic material, and its size is adapted to the third groove 103 to seal the light-transmitting component of the observation window 40.

[0032] The window slat 50 provides a sealed and protective function for the observation window 40, preventing dust, moisture and other impurities from entering the room, while ensuring good light transmission and not affecting the observation effect. The plastic material is both lightweight and economical.

[0033] In this embodiment, the fixing plate 20 and the pin post 30 can be manufactured in various ways, including but not limited to a detachable fixed connection fitting process and a mold integral molding process. The following are examples: The first type is a detachable and fixed connection fitting process: a first groove 101 and a second groove 102 are opened on one end face of the door panel 10, the fixing plate 20 and the pin 30 correspond to the shape of the first groove 101 and the second groove 102, and the fixing plate 20 and the pin 30 are respectively embedded in the first groove 101 and the second groove 102.

[0034] Furthermore, the depth h1 of the first groove 101 and the second groove 102 is less than the thickness h2 of the door panel 10.

[0035] The first groove 101 and the second groove 102 are adapted to the shape and size of the fixing plate 20 and the pin 30, respectively, and provide a preset structure for the installation space of the metal components. The shape includes, but is not limited to, cylinders, polygons, etc. The first groove 101 and the second groove 102 are used to accurately position the fixing plate and the pin, ensuring that the metal components are tightly connected to the door panel, avoiding loosening or displacement after installation, and at the same time, allowing the metal components to be embedded inside the door panel without affecting the appearance flatness of the door.

[0036] The second method is the integrated molding process: the door panel 10, the fixing plate 20, and the pin 30 are integrally molded. The height of the fixing plate 20 and the pin 30 is less than the thickness h2 of the door panel 10. This process can ensure that the metal components are tightly bonded to the melamine door panel, avoid gaps during assembly, and further improve the connection stability.

[0037] In summary, this utility model has the following advantages: This utility model, by embedding a metal fixing plate 20 and a pin post 30 at the key connection position of the door panel 10, utilizes the high strength and high stability characteristics of the metal components to effectively transfer the force on the door panel 10 to the metal parts. This completely solves the problem of local stress concentration cracking caused by the low shear strength of melamine material, and at the same time avoids the connection loosening failure caused by creep of plastic under long-term stress, significantly improving the connection stability and service life of the door.

[0038] The door panel 10 of this utility model is made of melamine resin material, and metal material is used only in key connection parts. Compared with the traditional all-metal frame fixing or plastic-metal composite structure, the amount of metal material used is greatly reduced, and the raw material cost is reduced. At the same time, the door panel and metal components adopt a mold integral molding process, which eliminates complicated subsequent assembly steps, simplifies the production process, improves production efficiency, and is conducive to large-scale production. The observation window on the door panel 10 of this utility model meets the usage requirements of observing the indoor status without opening the door, and is especially suitable for special scenarios such as clean rooms. The plastic window is removable and replaceable, making maintenance convenient. The metal components are embedded in the groove of the door panel and are not exposed on the surface of the door panel, ensuring the flatness and decoration of the door appearance. Moreover, the observation window can be flexibly arranged in an array or symmetrically to adapt to different decoration requirements.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
