Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and more specifically to an integrated structure of a metal door and window compensation frame and a screen frame. Background Technology
[0002] Currently, over 90% of inward-opening metal doors and windows (such as thermally broken aluminum doors and windows) do not have a pre-designed structure for screen installation. When users need to install screens, they can only use an "external" solution: fixing an independent screen frame to the outside of the door or window with bolts or adhesive, and then installing the screen sash. This method has significant drawbacks: the externally attached screen frame relies on only 4-6 bolts to bear the entire load, and the bolt holes are prone to stress fatigue under long-term wind loads, leading to the risk of the entire screen falling off. Industry reports show that there are over 200 screen falling accidents annually in coastal areas; the screen frame and window sash use a hard contact without an elastic sealing structure. When the wind speed is >8m / s, airflow through the gaps causes high-frequency vibration noise (measured at 45-60dB), and water seepage is likely to occur during heavy rain. To solve this problem, the industry is gradually promoting an "integrated window and screen" design (integrating the screen into the main frame of the door or window), but a fundamental bottleneck still exists: users must bear the cost of the screen sash regardless of whether they need it, and it cannot be disassembled for cleaning. Furthermore, due to the lack of pre-existing structural features during the installation of previous doors and windows, it was impossible to upgrade to an integrated window screen system.
[0003] Existing technologies cannot simultaneously meet the requirements of safety, adaptation to old windows, and on-demand use. Therefore, there is an urgent need for a metal door and window compensation frame with integrated screen frame structure, which is a problem that needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the present invention provides an integrated window screen structure for a metal door and window compensation frame that combines a screen frame and a window screen frame, which meets the requirements of safety, adaptation to old windows, and on-demand use.
[0005] To achieve the above objectives, this utility model provides the following technical solution, including a main frame of a door and window and an operable sash, with a compensation frame that is fixed to the outdoor side of the main frame of the door and window by bolts; a screen frame is detachably connected to the compensation frame; the compensation frame protrudes outward to the outdoor side to form an L-shaped support structure, the support is engaged with the bottom of the screen frame, and the protrusion depth is greater than the thickness of the screen frame.
[0006] Preferably, in the above-mentioned integrated screen structure of metal door and window compensation frame and screen frame, the inner side of the screen frame is provided with a rubber strip groove, and a sealing rubber strip with a hollow cavity structure is embedded in the groove.
[0007] The sealing strip has a double-lip design in its cross-section, with one lip contacting and sealing the opening fan.
[0008] Preferably, in the above-mentioned integrated window and screen structure of metal door and window compensation frame and screen frame, the L-shaped support of the compensation frame is provided with a quick-release slot; the bottom of the screen frame is provided with a barb that matches the quick-release slot, forming a snap-fit connection.
[0009] Preferably, in the above-mentioned integrated window and screen structure of metal door and window compensation frame and screen frame, the thickness of the compensation frame is 1.2-1.5 times the wall thickness of the main frame profile of the door and window, and its protruding part is provided with reinforcing ribs.
[0010] Preferably, in the above-mentioned integrated window and screen structure of metal door and window compensation frame and screen frame, a waterproof adhesive strip groove is provided at the connection between the compensation frame and the main frame of the door and window, and the groove is filled with sealant.
[0011] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated window screen structure with a metal door and window compensation frame and a screen frame. This utility model completely eliminates the risk of bolt fatigue and detachment of traditional external screens by integrating the compensation frame and the screen frame with a rigid connection. The soft connection design based on the double-lip sealing strip suppresses wind noise and enhances waterproofing. The outward protruding structure of the compensation frame makes the screen frame completely separate from the thickness space of the door and window opening sash, improving sound insulation and heat insulation. The quick-release slot and barb structure realizes quick disassembly and assembly, and users can disassemble the screen seasonally. Attached Figure Description

Obviously, the drawings described below are only embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.
[0013] Figure 1 The attached figure is a schematic cross-sectional view of the overall structure of this utility model. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see the appendix Figure 1 This utility model discloses an integrated structure of a metal door and window compensation frame and a screen window frame.
[0016] This utility model includes a main frame 1 for doors and windows and an operable sash 2. A window repair frame 3 is provided, which is fixed to the outdoor side of the main frame 1 by bolts. A screen window 4 frame is detachably connected to the window repair frame 3. The window repair frame 3 protrudes outward to the outdoor side to form an L-shaped support structure. The support is engaged with the bottom of the screen window 4 frame, and the protrusion depth is greater than the thickness of the screen window 4 frame.
[0017] To further optimize the above technical solution, the inner side of the screen window frame 4 is provided with a rubber strip groove, and a sealing rubber strip with a hollow cavity structure is embedded in the groove.
[0018] The sealing strip has a double-lip design in cross-section, with one lip contacting and sealing the opening fan 2.
[0019] To further optimize the above technical solution, the L-shaped support of the window frame 3 is provided with a quick-release slot; the bottom of the screen window 4 frame is provided with a barb that matches the quick-release slot, forming a snap-fit connection.
[0020] To further optimize the above technical solution, the thickness of the window frame 3 is 1.2-1.5 times the wall thickness of the main frame 1 of the door and window, and its protruding part is provided with reinforcing ribs.
[0021] To further optimize the above technical solution, a waterproof adhesive strip groove is provided at the connection between the window frame 3 and the main frame 1 of the door and window, and the groove is filled with sealant.
[0022] To further optimize the above technical solution, the compensation frame is vertically fixed to the outside of the main frame of the door and window by bolts to form a rigid support base. The L-shaped support converts the lateral wind pressure of the screen into vertical shear force, which is borne by the bolts (the traditional external type bears bending moment and is prone to overturning); the reinforcing ribs suppress the deformation of the support, and the wedge-shaped slope of the slot produces a self-locking effect.
