Description

Technical Field

[0001] This utility model relates to the field of architectural decorative grille technology, and in particular to an aluminum alloy door and window decorative grille structure. Background Technology

[0002] In the field of modern architectural decoration, aluminum alloy doors and windows are widely used in various building projects, including residential buildings, commercial complexes, and public buildings, due to their superior performance, such as excellent corrosion resistance, high strength-to-weight ratio, and excellent processing performance. As consumers' demands for both aesthetic appeal and functional practicality in architecture continue to rise, aluminum alloy doors and windows are no longer limited to basic functions like lighting and ventilation; they have become an important component of building facade decoration. Against this backdrop, decorative grilles for aluminum alloy doors and windows have emerged. They not only enhance the layering and artistic expression of doors and windows through rich design options (such as vertical stripes, grids, and custom patterns), but also provide a certain degree of protection (preventing children from climbing and blocking foreign objects from entering), sun shading (reducing direct sunlight and lowering indoor energy consumption), and privacy protection (avoiding direct views from the outside to the inside), becoming a key component for enhancing the overall value of aluminum alloy doors and windows. Despite the aforementioned advantages and increasingly widespread application of aluminum alloy door and window decorative grilles in the market, existing products still have many shortcomings that urgently need to be addressed in actual use and installation, making it difficult to fully meet the requirements of modern architecture for efficient construction, robust durability, and integrated aesthetics.

[0003] The prior art discloses an aluminum alloy door and window with a detachable safety grille, which includes a door and window frame and a safety grille. The safety grille is fixedly connected to the four corners of the frame with mounting plates. The four corners of one side of the door and window frame are fixedly embedded with a housing. The housing has a mounting groove on one side surface. The mounting plate is inserted into the housing through the mounting groove. One end of the mounting plate is provided with a mounting component. The housing has a disassembly mechanism inside. The disassembly mechanism includes screws, a drive plate, a square bar, two movable blocks, two connecting rods, and two fixed plates. Although the patent still has problems such as insufficient ease of installation (it requires pre-drilling holes and positioning in the door and window frame or wall, and then fixing the grille components one by one with multiple fasteners), connection stability is easily affected by the environment (long-term exposure to the outdoor environment makes it susceptible to corrosion due to rain, humidity, ultraviolet rays, etc., and temperature changes cause thermal expansion and contraction of aluminum alloy materials), poor aesthetic coordination and customization adaptability (most of the grille connectors are exposed, with screws, buckles and other parts directly exposed on the grille surface, which destroys the integrity and aesthetic lines of the grille shape).

[0004] In view of the above-mentioned shortcomings of existing aluminum alloy door and window decorative grilles, there is an urgent need to develop a new type of aluminum alloy door and window decorative grille structure that is easy to install, has a stable connection and is aesthetically pleasing, and has good compatibility with door and window functions. Therefore, this utility model proposes an aluminum alloy door and window decorative grille structure to provide greater convenience for the installation and replacement of aluminum alloy door and window decorative grilles.
