[0029] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.

[0030] Please refer to Figures 1 to 4 The reliable concealed screen door and window of this application embodiment includes a composite window frame 10, a movable window sash 20 disposed on the composite window frame 10, and a concealed screen assembly 30 disposed within the composite window frame 10.

[0031] The movable window sash 20 opens / closes relative to the composite window frame 10 to meet the needs of ventilation, lighting and sealing. The movable window sash 20 is equipped with composite glass 40 to meet the needs of sound insulation, heat insulation and safety performance of doors and windows.

[0032] In the specific implementation process, the composite window frame 10 includes a window stile 1 and a fixed side 2 arranged opposite to each other. The movable window sash 20 is connected to the fixed side 2, and the movable window sash 20 can be set on the fixed side 2 by means of hinge. That is, the movable window sash 20 can rotate relative to the fixed side 2 to connect with or maintain a distance from the window stile 1, thereby realizing the opening / closing of the movable window sash 20 relative to the composite window frame 10.

[0033] The fixed edge 2 has an installation space 21, and the folded screen 30 is configured in the installation space 21 to achieve the purpose of hiding the screen in the door and window.

[0034] Furthermore, the window stile 1 includes a first frame 11, a second frame 12, and at least two intermediate profiles 13. The first frame 11 and the second frame 12 are arranged opposite to each other, and the intermediate profiles 13 are arranged at intervals. Their two ends are respectively connected to the first frame 11 and the second frame 12 to form a stable load-bearing frame. The intermediate profile 13 near the fixed edge 2 is provided with a fastening seat 3. When the movable window sash 20 is opened relative to the composite window frame 10, the folding screen 30 opens from the fixed edge 2 toward the window stile 1 and is fixed on the fastening seat 3, or the folding screen 30 folds and retracts from the window stile 1 toward the fixed edge 2 into the installation space 21. That is, the fastening seat 3 provides a reliable fixing point for the folding screen 30, thereby bearing the force of the folding screen 30 in the tensile state.

[0035] To improve the connection strength between the fastening seat 3 and the intermediate profile 13, a first connecting adhesive layer 41 is provided on the side of the fastening seat 3 facing the intermediate profile 13. The first connecting adhesive layer 41 fixes the fastening seat 3 and the intermediate profile 13. The first connecting adhesive layer 41 buffers the tensile impact force of the fastening seat 3 and improves the overall anti-loosening and fatigue resistance of the structure, thereby improving the reliability of the internal structure of the hidden screen door and window.

[0036] In one example, the fastening seat 3 is integrally connected to the fixing body 31 on the side facing the intermediate profile 13, and the first connecting adhesive layer 41 fixes the fixing body 31 and the intermediate profile 13 respectively. The outer surface of the fixing body 31 may be provided with a corrugated pattern or a matrix hole to enhance the firmness with the first connecting adhesive layer 41.

[0037] Furthermore, the two ends of the fixing body 31 maintain gaps with the outer walls of the first frame 11 and the second frame 12, respectively. A second connecting adhesive layer 42 is provided in the gap. The second connecting adhesive layer 42 fixes the fixing body 31 and the first frame 11, as well as fixes the fixing body 31 and the second frame 12, thereby achieving a multi-faceted and stable connection of the fastening seat 3 and improving its load-bearing and durability performance.

[0038] In one example, the first frame 11 and the second frame 12 are provided with a first snap-fit ​​groove 61 on their opposite sides. The first snap-fit ​​groove 61 protrudes from the first frame 11 and the second frame 12 respectively. The two ends of the intermediate profile 13 are provided with first snap-fit ​​blocks 62, which are matched in the first snap-fit ​​groove 61.

[0039] Preferably, the first snap-fit ​​block 62 is snapped into the first snap-fit ​​slot 61.

[0040] This ensures a stable connection between the first frame 11, the second frame 12, and the intermediate profile 13.

[0041] Among them, the two ends of the fixing body 31 facing the middle profile 13 are provided with fixing grooves 32 opposite to the first snap-fit ​​groove 61. The outer wall of the first snap-fit ​​groove 61 extends into the fixing groove 32 to further ensure the connection stability between the fastening seat 3 and the middle profile 13.

[0042] Furthermore, a third connecting adhesive layer 43 is filled between the outer walls of the fixing groove 32 and the first snap-fit ​​groove 61 to further enhance the tensile and vibration resistance of the fastening seat 3, thereby improving the reliability of the internal structure of the hidden screen door and window.

[0043] The first snap-fit ​​groove 61 includes a first groove block 601 and a second groove block 602 integrally connected to the outer walls of the first frame 11 and the second frame 12. The first groove block 601 and the second groove block 602 are arranged opposite to each other, and the first groove block 601 and the second groove block 602 together form a groove that gradually narrows towards the first snap-fit ​​block 62. This allows for self-guiding positioning and clamping fixation after the first snap-fit ​​block 62 is inserted. In other words, the gradually narrowing groove not only improves the alignment accuracy of the assembly, but also reduces the risk of loosening of the snap-fit ​​parts during long-term use.

[0044] In addition, the outer wall portion of the first groove block 601 extends into the fixing groove 32.

[0045] In one example, the folded screen 30 has a fastening block 5 corresponding to the fastening seat 3 on the side facing the window stile 1. After the folded screen 30 is opened from the fixed edge 2 toward the window stile 1, the fastening block 5 is connected to the fastening seat 3 to fix the folded screen 30.

[0046] That is, by engaging the fastening block 5 with the fastening seat 3, the folding screen 30 is stably covered in the opening area of ​​the movable window sash 20 after it is opened, and is stably connected between the window stile 1 and the fixed edge 2.

[0047] Both the fastening block 5 and the fastening seat 3 are metal parts.

[0048] It is understood that the specific connection structure and function of the fastening block 5 and the fastening seat 3 in the embodiments of this application are available to those skilled in the art based on the prior art, and the structure and working principle of the fastening block 5 and the fastening seat 3 will not be described in detail here.

[0049] In one example, the folding screen 30 has a movable seat 7 on the side facing the window stile 1. A receiving cavity 71 is opened on one side of the movable seat 7. The folding screen 30 is folded and housed in the receiving cavity 71. The fastening block 5 is integrally connected to the movable seat 7. The movable seat 7 can move back and forth along the direction from the fixed edge 2 to the window stile 1. In use, after the movable window sash 20 is opened relative to the composite window frame 10, the movable seat 7 stretches the folding screen 30 along the direction from the fixed edge 2 to the window stile 1, so that it unfolds and covers the area of ​​the opened movable window sash 20. When it is necessary to close the movable window sash 20 or to store the folding screen 30, the movable seat 4 presses the folding screen 30 along the direction from the window stile 1 to the fixed edge 2 to fold it and store it back into the receiving cavity 71, thereby realizing the hiding and unfolding of the screen.

[0050] It should be noted that one end of the folded mesh 30 is fixedly connected to the inner wall of the fixed edge 2 within the installation space 21, and the other end of the folded mesh 30 is fixedly connected to the inner wall of one side of the receiving cavity 71.

[0051] In one example, the fastening seat 3, the folding screen 30, the first connecting adhesive layer 41 and the intermediate profile 13 are centrally symmetrical along the direction from the fixed edge 2 to the window stile 1, so as to ensure the balance and stability of the folding screen 30 when unfolding and retracting, and also to enhance the overall harmony of the door and window appearance.

[0052] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
