[0028] 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.
[0029] Please refer to Figures 1 to 3 The stable 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.
[0030] 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.
[0031] 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.
[0032] Furthermore, the fixed edge 2 includes a first frame 21, a second frame 22, and at least two intermediate profiles 23. The first frame 21 and the second frame 22 are arranged opposite each other and maintain an installation space 24. The intermediate profiles 23 are arranged at intervals and their two ends are respectively connected to the first frame 21 and the second frame 22 to enhance structural stability, so that the first frame 11 and the second frame 12 form an integrated frame structure, thereby ensuring the shape stability and load-bearing capacity of the installation space 24, so as to accommodate the hidden mesh assembly 30.
[0033] The hidden mesh assembly 30 is configured in the installation space 24. The hidden mesh assembly 30 includes a fixed base 3, a movable base 4 and a folded mesh 5. The fixed base 3 is connected to the intermediate profile 23. The movable base 4 is arranged on one side of the fixed base 3, and a receiving cavity 41 is opened on the side of the movable base 4 facing the fixed base 3. The folded mesh 5 is housed in the receiving cavity 41, and both ends of the folded mesh 5 are connected to the fixed base 3 and the inner wall of the receiving cavity 41 on the side away from the fixed base 3, respectively.
[0034] In use, when the movable window sash 20 is opened relative to the composite window frame 10, the movable seat 4 stretches and folds the screen 5 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 and hide the screen assembly 30, the movable seat 4 presses and folds the screen 5 along the direction from the window stile 1 to the fixed edge 2, folds it, and stores it back into the receiving cavity 41, thereby realizing the hiding and unfolding of the screen.
[0035] Furthermore, the fixing seat 3 is connected to the intermediate profile 23, and the two ends of the folded mesh 5 are respectively connected to the fixing seat 3 and the inner wall of the receiving cavity 41 on the side away from the fixing seat 3, thereby ensuring the structural reliability of the hidden mesh assembly 30 within the composite window frame 10.
[0036] In one example, the fixing base 3 includes a base plate 31 and fixing claws 32 integrally connected to the base plate 31. The two fixing claws 32 are arranged opposite to each other. One end of the folded mesh 5 is snapped between the two fixing claws 32. The base plate 31 is connected to the intermediate profile 23 to ensure that the fixing base 3 is firmly connected to the intermediate profile 23.
[0037] In order to enhance the fixing strength, a first connecting adhesive layer 61 is provided between the base plate 31 and the intermediate profile 23. The first connecting adhesive layer 61 can be made of high-strength weather-resistant adhesive, which can maintain the connection stability for a long time and also has waterproof and vibration-proof functions.
[0038] Furthermore, the two ends of the base plate 31 maintain gaps with the outer walls of the first frame 21 and the second frame 22, respectively. A second connecting adhesive layer 62 is provided in the gap. The second connecting adhesive layer 62 fixes the base plate 31 and the first frame 21, as well as the base plate 31 and the second frame 22. Thus, the second connecting adhesive layer 62 can absorb the slight displacement caused by temperature and humidity changes or mechanical stress while fixing the base plate 31 and the first frame 21 and the second frame 22, thereby improving the durability of the entire window.
[0039] In one example, for ease of installation and positioning, the first frame 21 and the second frame 22 are provided with a first snap-fit groove 101 on their facing sides, and the two ends of the intermediate profile 23 are provided with a first snap-fit block 102, which is matched in the first snap-fit groove 101.
[0040] Furthermore, the two ends of the base plate 31 facing the middle profile 23 are provided with fixing grooves 311 opposite to the first snap-fit groove 101. The outer wall portion of the first snap-fit groove 101 extends into the fixing groove 311, thereby further enhancing the connection strength between the base plate 31 and the first frame 21 and the second frame 22.
[0041] Furthermore, a third bonding adhesive layer 63 is filled between the outer wall of the fixing groove 311 and the first snap-fit groove 101 to further enhance the bonding strength and sealing performance.
[0042] In one example, to ensure the stability of the folded screen 5 after it is stretched into place, the movable seat 4 is provided with a fastening block 42 at the end opposite to the folded screen 5. This ensures that after the movable seat 4 stretches the folded screen 5 from the fixed edge 2 toward the window stile 1, the fastening block 42 is connected to the fastening seat (not shown) opposite to the window stile 1. That is, the fastening block 42 can be engaged with the fastening seat at the opposite position of the window stile 1, thereby preventing the screen from shrinking or shaking under wind pressure.
[0043] To prevent the ends of the folded mesh 5 from coming loose during use, the ends of the fixing claws 32 are integrally connected with arc-shaped clamping bodies 32a. The arc-shaped clamping bodies 32a of the two fixing claws 32 are bent face to face towards the folded mesh 5 to clamp the ends of the folded mesh 5. That is, the arc-shaped clamping bodies 32a can stably hold the ends of the folded mesh 5 while avoiding sharp angle clamping that could damage the mesh.
[0044] In addition, the fixed seat 3, the movable seat 4 and the folding screen 5 are symmetrical along the direction from the fixed edge 2 to the window stile 1 to ensure the balance of the screen's unfolding and retraction, and also to enhance the overall harmony of the door and window's appearance.
[0045] It is understood that the structural design of the fixing seat 3 in this application ensures the connection reliability of the hidden screen assembly 30 within the composite window frame 10. The specific structure and function of the folded screen 5 are known to those skilled in the art based on the prior art, and the structure and working principle of the folded screen 5 will not be described in detail here.
[0046] 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.
