[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The aluminum-plastic co-extruded composite profile energy-saving doors and windows, through the reinforcement plate to provide stable support for the main rod of the installation, can significantly improve the overall structural strength and anti-deformation ability of the profile, avoid bending or warping of the doors and windows during long-term use, wind pressure or installation, ensure the sealing and stability of the doors and windows, extend the service life, and are suitable for complex use environments such as high-rise buildings and windy areas. At the same time, the support structure does not affect the energy-saving thermal conductivity of the profile itself, taking into account both strength and energy-saving core requirements. The sound insulation cotton can greatly improve the sound insulation and noise reduction performance of the doors and windows, effectively blocking outdoor traffic noise, environmental noise and other noises from being transmitted to the room, creating a quiet and comfortable living or office environment, and meeting the stringent sound insulation requirements in different scenarios.

[0020] (2) The aluminum-plastic co-extruded composite profile energy-saving doors and windows achieve convenient connection between the main installation rod and the secondary installation rod through the limiting block. This installation method does not require complicated tools or professional skills training, and workers can quickly get started, which greatly reduces the installation difficulty and construction threshold, shortens the installation time of a single set of doors and windows, and is especially suitable for batch construction scenarios, effectively improving the overall construction efficiency and reducing labor input costs. At the same time, the connection structure design is precisely adapted, and there is no need to repeatedly adjust the alignment during installation. It can not only ensure the connection between the main installation rod and the secondary installation rod, avoiding loosening caused by long-term use or environmental vibration, but also ensure the sealing performance and structural stability of the doors and windows after installation, without affecting the core functions such as energy saving and sound insulation. It simplifies the construction process while taking into account the reliability of use, reducing construction and later maintenance costs, and fully meeting the multiple needs of building construction scenarios for installation convenience, efficiency and stability, thereby improving the product's construction adaptability and market competitiveness.

[0021] (3) The aluminum-plastic co-extruded composite profile energy-saving doors and windows achieve efficient indoor and outdoor ventilation through automatic ventilation fans. Air circulation can be completed without opening the glass, avoiding the large-scale direct exchange of indoor and outdoor air caused by traditional window ventilation. It effectively reduces the large fluctuations in indoor temperature. Especially in scenarios where air conditioning is used for heating, heating is running, or there are large temperature differences in spring and autumn, it can retain the original suitable indoor temperature to the maximum extent and reduce the energy consumption of temperature control equipment, which meets the core requirements of energy-saving doors and windows. At the same time, this ventilation method not only meets the need for fresh indoor air, but also eliminates concerns about dust, noise, and mosquito intrusion caused by opening windows, improving the comfort and convenience of living or working. No additional ventilation accessories are required. On the basis of ensuring energy saving, the functionality of the product is expanded, further enhancing the practicality and market competitiveness of the product. Attached Figure Description
