Description

Technical Field

[0001] The present invention belongs to the technical field of U-PVC plastic steel windows, and particularly relates to a new type of aluminum-plastic U-PVC window glass sash and screen sash universal profile with flat frames inside and outside. Background Art

[0002] The aluminum-plastic U-PVC window glass sash and screen sash is a new type of door and window profile design that combines aluminum-plastic composite materials with U-PVC (unplasticized polyvinyl chloride). It is developed specifically for the needs of modern buildings. Its core feature is to integrate the glass window sash (glass sash) and the screen window sash (screen sash) into a flat frame structure inside and outside, achieving universal and multi-functional installation.

[0003] In the traditional design of aluminum-plastic U-PVC window glass sash and screen sash, there are often many inconveniences in the installation of the window sash and the screen sash. On the one hand, the installation positions of the window sash and the screen sash are easily limited, making it difficult to achieve the design of flat frames inside and outside, which affects the aesthetics and practicality of the window. On the other hand, the installation process of the traditional screen window is cumbersome, and the connection between the screen window and the window frame is not tight enough, easily allowing mosquitoes to enter the room. At the same time, the screen window also lacks a stable handle position, causing inconvenience in use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a new type of aluminum-plastic U-PVC window glass sash and screen sash universal profile with flat frames inside and outside.

[0005] The technical solution adopted to solve the above technical problem is: a new type of aluminum-plastic U-PVC window glass sash and screen sash universal profile with flat frames inside and outside, including an outer frame assembly. On one side of the outer frame assembly, an aluminum-plastic outward-opening assembly and an aluminum-plastic double inward-opening assembly are respectively installed. The outer frame assembly, the aluminum-plastic outward-opening assembly, and the aluminum-plastic double inward-opening assembly all adopt European standard grooves.

[0006] Further, the outer frame assembly includes two casement frames and a T-shaped mullion. The two casement frames are located on the outermost sides, and the T-shaped mullion is located between the two casement frames. The aluminum-plastic outward-opening assembly and the aluminum-plastic double inward-opening assembly are respectively located between one of the casement frames and the T-shaped mullion. Inside the casement frames and the T-shaped mullion, first steel liners are fixedly connected, and the first steel liners are connected to form a whole.

[0007] Through the above technical solution, the stability and strength of the outer frame assembly are achieved. At the same time, the setting of the first steel liners also enhances the anti-deformation ability of the outer frame assembly. In addition, the design of the casement frames and the T-shaped mullion makes the installation positions of the window sash and the screen sash more flexible, no longer limited to the installation positions in the traditional design, thus achieving the design of flat frames inside and outside, improving the aesthetics and practicality of the window. At the same time, because the first steel liners are connected to form a whole, the stability of the entire outer frame assembly is stronger.

[0008] Further, a first aluminum frame is fixedly connected by meshing on one side of the casement frame. A first rubber strip is fixedly connected between the first aluminum frame and a connecting end of the casement frame away from the outer side. A second aluminum frame is fixedly connected by meshing on one side of the T-shaped mullion. The second aluminum frame and the end of the T-shaped mullion close to the casement frame are fixedly connected by another first rubber strip.

[0009] Through the above technical solution, the connection stability between the casement frame, the T-shaped mullion and the aluminum frame is further enhanced, effectively preventing loosening or deformation caused by long-term use or external forces. The setting of the first rubber strip not only plays a sealing role, but also improves the overall sound insulation and heat insulation performance, providing a more comfortable living environment for users. At the same time, the design of the first aluminum frame and the second aluminum frame makes the installation of the window sash and the screen sash more convenient, and can ensure the stability and sealing performance after installation, thus further improving the use effect and safety of the window.

[0010] Further, fixed frames are respectively fixedly connected by meshing between the casement frame and the T-shaped mullion away from the aluminum-plastic outward-opening assembly and the aluminum-plastic double inward-opening assembly. The fixed frames are located on the side away from the first aluminum frame and the second aluminum frame. Second rubber strips are respectively fixedly connected to the inner top corner ends of the two fixed frames close to each other.

[0011] Through the above technical solution, the sealing performance between the casement frame and the T-shaped mullion is effectively improved, further preventing the penetration of air, moisture or dust. The setting of the second rubber strip not only enhances the connection tightness between the frames, but also provides additional sound insulation and heat insulation effects, making the heat preservation and energy-saving performance of the window more prominent. In addition, the design of the fixed frame enables the window sash and the screen sash to fit more closely when closed, improving the overall sealing and stability, thereby enhancing the wind pressure resistance of the window and ensuring the safety and comfort of users.

[0012] Further, the aluminum-plastic outward-opening assembly includes two symmetrically arranged first casement sashes. Third lining steels are arranged inside both of the first casement sashes. A third aluminum frame is fixedly connected by meshing on one side of the first casement sash. The third aluminum frame and the connecting end of the first casement sash are fixedly connected by another casement frame. First mounting frames are respectively rotatably connected to the ends of the two first casement sashes away from each other. The two first mounting frames are attached to both ends of the first casement sash through first rubber strips. The two first mounting frames are respectively fixedly connected by meshing with the T-shaped mullion in the middle and the casement frame on the other side. Outer-opening sashes are respectively rotatably connected to the sides of the two first mounting frames away from the first casement sashes. Second lining steels are arranged inside the outer-opening sashes.

[0013] Through the above technical solutions, not only the structural strength and stability of the aluminum-plastic outward-opening component are enhanced, but also the window opens and closes more smoothly, reducing the problems of loosening or deformation caused by long-term use. The first casement sash is fixedly connected to the third aluminum profile frame in a meshing manner, and through the further fixation of the casement frame, the stability of the entire outward-opening component is ensured, improving the safety performance of the window. At the same time, the first installation frame is attached to both ends of the first casement sash through the first rubber strip, effectively improving the sealing performance of the window, preventing the penetration of air, moisture or dust, and further enhancing the heat preservation and energy-saving effects of the window. In addition, the second steel liner provided on the inner side of the outward-opening sash not only increases the load-bearing capacity of the outward-opening sash, but also improves the overall wind pressure resistance of the window, ensuring the safety and comfort of users.

[0014] Furthermore, the aluminum-plastic double inward-opening component includes two symmetrically arranged second installation frames. The two second installation frames are respectively rotatably connected to the T-shaped middle stile located in the middle and the casement frame located on the other side. A sealing plug is fixedly connected to the middle of the mutually remote sides of the two second installation frames through the first rubber strip. The two sealing plugs are respectively fixedly connected to the T-shaped middle stile and the casement frame located on the other side in a meshing manner.

[0015] Through the above technical solutions, not only the sealing performance of the aluminum-plastic double inward-opening component is improved, but also its structural stability and durability are enhanced. The setting of the sealing plug effectively fills the gaps between the second installation frame, the T-shaped middle stile and the casement frame, avoiding the penetration of air, moisture or dust, and further improving the heat preservation, sound insulation and energy-saving effects of the window. At the same time, the rotational connection of the second installation frame with the T-shaped middle stile and the casement frame, and the meshing and fixed connection of the sealing plug ensure the stability and smoothness of the aluminum-plastic double inward-opening component when opening and closing, reducing the problems of loosening or deformation caused by long-term use.

[0016] Furthermore, the two second installation frames are fixedly connected to a second pressing strip at their inner ends in a meshing manner. The sides of the two second pressing strips away from the second installation frames are respectively fixedly connected to the casement frame and the T-shaped middle stile through the first rubber strip. First inward-opening sashes are provided on the sides of the two second pressing strips away from the second installation frames. The two first inward-opening sashes are respectively rotatably attached to the second aluminum profile frame and the first aluminum profile frame. A second inward-opening sash is provided inside the first inward-opening sash. A first pressing strip is fixedly connected to the middle of the second inward-opening sash in a meshing manner.

[0017] Through the above technical solutions, not only the structural stability and sealing performance of the aluminum-plastic double inward-opening assembly are further enhanced, but also the flexibility and versatility of the window are improved. The setting of the second bead effectively enhances the sealing effect at the edge of the window through the fixed connection of the first rubber strip with the casement frame and the T-shaped mullion, preventing the penetration of external air, moisture or dust, and further improving the heat insulation, sound insulation and energy-saving performance of the window. At the same time, the design of the first inward-opening sash and the second inward-opening sash enables the window to be flexibly opened or closed as needed, meeting the diverse needs of users for window use. The rotational fit of the first inward-opening sash with the second aluminum frame and the first aluminum frame, and the first bead meshing and fixedly connected to the middle of the second inward-opening sash ensure the stability and smoothness of the window when opening and closing, reducing the problems of loosening or deformation caused by long-term use.

[0018] Further, a second notch is provided on the side of the first mounting frame close to the outward-opening sash. The size of the second notch is 14×3.2×18.4 (unit: mm). A first notch is provided at the corresponding position of the middle of the outward-opening sash and the first mounting frame. The size of the first notch is 15×3×20 (unit: mm). A groove is provided in the middle of the first mounting frame. The groove is provided at the connection with the outward-opening sash. The size of the groove is 33.5×15×33.5 (unit: mm). A chamfer of R10 (unit: mm) is provided on one side of the groove.

[0019] Through the above technical solutions, the screen of the outward-opening sash is placed on the outermost side to make way for the handle position. At the same time, the U-shaped notch of the groove realizes the integrated design of the window screen, that is, the glass sash opens outward and the screen sash opens inward. On the premise of the same window frame, the outward-opening sash partially overlaps with the first mounting frame, improving the aesthetics, and the second lining steel can be placed inside the outward-opening sash, greatly improving the strength.

[0020] Further, a third notch is provided at the bottom end of the second inward-opening sash. The size of the third notch is 10×2.9×14.6 (unit: mm). A fourth notch is provided on one side of the second inward-opening sash. The fourth notch is meshed and fixedly connected to one end of the first bead. A fifth notch is provided at one end of the first inward-opening sash away from the fitting end. The size of the fifth notch is 2.9×4.2×7.8 (unit: mm). A sixth notch is provided at the end of the second bead away from the second mounting frame. The size of the sixth notch is 2.9×2.2×7.8 (unit: mm). The above notches are all European standard notches.

[0021] Through the above technical solution, the first inward-opening sash and the second inward-opening sash can be stably and firmly installed in the first installation frame and the second installation frame. At the same time, the outward-opening sash can also be stably connected to the first installation frame through the cooperation of the first notch and the second notch. The sizes of the notches are precisely designed to ensure the tight fit between the components, avoiding installation problems caused by size mismatches. In addition, the first pressing strip and the second pressing strip are fixedly engaged with the corresponding notches of the inward-opening sash through their respective notches, further enhancing the stability and firmness of the window sash structure.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. By applying the European standard groove design of the traditional broken bridge aluminum window to the aluminum-plastic U-PVC window, the present invention places the screen mesh on the outermost side, creating space for the handle. To achieve the integration of window screen, outward-opening glass sash, and inward-opening screen sash, a U-shaped notch of the secondary frame is innovatively dug on the basis of the same frame type, enabling the window screen to partially overlap with the secondary frame. Under the same frame type, the double inward-opening design with flush interior and exterior, as well as the window screen integration design of outward-opening glass sash and inward-opening screen sash, are simultaneously realized, solving the problems of difficult installation of traditional window screens, easy contact with the secondary frame, and lack of handle position.
