Description

Technical Field

[0001] This application relates to the field of door and window sealing technology, and in particular to a sealing structure for doors and windows. Background Technology

[0002] Aluminum alloy doors and windows are made of aluminum alloy profiles. They are lightweight, corrosion-resistant, high-strength, easy to surface treat, and come in a variety of styles. Aluminum alloy doors and windows are the most basic configuration for ordinary residences. Aluminum alloy doors and windows have strong fire resistance, long service life, and energy saving. They are also the most important factors affecting lighting, ventilation, and comfort. Doors and windows are made of energy-saving aluminum alloy extruded profiles for frames, mullions, and sashes.

[0003] Regarding the aforementioned technologies, the inventors believe that traditional sealing strips are prone to significant degradation in sealing performance due to aging and deformation after long-term use. Furthermore, the inadequate design of the sealing structure when doors and windows are closed allows outside air and rainwater to easily seep into the room through gaps. Therefore, a sealing structure for doors and windows is proposed to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this application provides a sealing structure for doors and windows.

[0005] The sealing structure for doors and windows provided in this application adopts the following technical solution:

[0006] A sealing structure for doors and windows includes a mounting frame. Multiple slide rails are fixedly connected to the inner walls of both sides of the mounting frame. A first door / window and a second door / window are provided on the inner wall of the mounting frame. The first and second doors / windows are slidably connected to the multiple slide rails. A first expansion block is fixedly connected to the outer wall of the first door / window, and a main sealing groove is formed on the outer wall of the first expansion block. A second expansion block is fixedly connected to the outer wall of the second door / window, and a main sealing plate is fixedly connected to the outer wall of the second expansion block. The main sealing plate is adapted to the main sealing groove. A fixing component is fixedly connected to the outer wall of the second door / window.

[0007] Preferably, the outer wall of the main sealing plate is provided with a fixing groove, and the fixing groove is adapted to the fixing component.

[0008] Preferably, the fixing component includes a fixing plate, which is slidably connected to the second door / window and adapted to the fixing groove. A support plate is fixedly connected to the outer wall of the fixing plate, and two spring members are provided between the support plate and the second door / window. The two spring members are fixedly connected to the support plate and the second door / window, and a handle is fixedly connected to the outer wall of the fixing plate.

[0009] Preferably, auxiliary sealing grooves are provided on both inner walls of the mounting frame, and auxiliary sealing plates are fixedly connected to the outer side walls of the first and second doors and windows, wherein the auxiliary sealing plates are adapted to the auxiliary sealing grooves.

[0010] Preferably, a sealing strip is fixedly installed on the outer wall of the main sealing plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By configuring a first expansion block and a second expansion block, the two blocks are aligned, allowing the main sealing groove inside the first expansion block to align with the main sealing plate on the second expansion block. This allows the main sealing plate to enter the main sealing groove, working in conjunction with the auxiliary sealing plates on both sides to seal the first and second doors / windows. Simultaneously, the fixing plate in the fixing assembly is fixed to the fixing groove and provides further sealing, further improving the airtightness between the first and second doors / windows. Compared to existing technologies, this method can seal larger gaps between the door / window frame and the door / window sash, effectively blocking most rainwater and dust intrusion, forming a sealed barrier. This significantly improves the overall sealing performance of the doors and windows, making the indoor environment quieter and more comfortable. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 Figure 4 provides a further detailed description of this application.

[0019] Example 1:

[0020] A sealing structure for doors and windows includes a mounting frame 1. Multiple slide rails 4 are fixedly connected to the inner walls of both sides of the mounting frame 1. A first door / window 2 and a second door / window 3 are provided on the inner wall of the mounting frame 1. The first door / window 2 and the second door / window 3 are slidably connected to the slide rails 4. The bottom and top of the first door / window 2 and the second door / window 3 are respectively slidably connected to the slide rails 4, allowing the first door / window 2 and the second door / window 3 to slide and move. The first door / window 2 and the second door / window 3 are slightly misaligned. A first expansion block 14 is fixedly connected to the outer wall of the first door / window 2. The outer wall of the first expansion block 14 has a main sealing groove 13. A second expansion block 15 is fixedly connected to the outer wall of the second door / window 3. The first expansion block 14 and the second expansion block 15 correspond to each other. In the gap between the first window 2 and the second window 3, and the outer wall of the second expansion block 15 is fixedly connected to the main sealing plate 10, the main sealing plate 10 is adapted to the main sealing groove 13. When the first window 2 and the second window 3 are moved to close the window as a whole, the main sealing plate 10 and the main sealing groove 13 are engaged, thereby sealing the gap between the first window 2 and the second window 3 and improving the sealing performance between the first window 2 and the second window 3. The outer wall of the second window 3 is fixedly connected to the fixing component, which can fix the first window 2 and the second window 3, and at the same time improve the sealing effect of the main sealing plate 10 and the main sealing groove 13, further improving the sealing performance between the first window 2 and the second window 3.

[0021] Reference Figure 4 The outer wall of the main sealing plate 10 is provided with a fixing groove 9, and the fixing groove 9 is adapted to the fixing component, so that the fixing component engages with the 0, thereby fixing the main sealing plate 10 and completing the fixing between the first door and window 2 and the second door and window 3. At the same time, the fixing component engages with the fixing groove 9, which provides an additional sealing effect between the main sealing plate 10 and the main sealing groove 13.

[0022] Reference Figure 3 The fixing assembly includes a fixing plate 5, which is slidably connected to the second door / window 3 and adapted to the fixing groove 9. A support plate 7 is fixedly connected to the outer wall of the fixing plate 5, and two spring members 6 are provided between the support plate 7 and the second door / window 3. The two spring members 6 are fixedly connected to the support plate 7 and the second door / window 3. A handle 8 is fixedly connected to the outer wall of the fixing plate 5. By pulling the handle 8, the handle 8 causes the fixing plate 5 to retract. When the main sealing plate 10 enters the main sealing groove 13, the pull on the handle 8 is released, which causes the spring members 6 on both sides to cause the support plate 7 to rebound, ensuring that the fixing plate 5 and the fixing groove 9 are engaged, thus completing the fixing of the main sealing plate 10 and further completing the fixing between the first door / window 2 and the second door / window 3.

[0023] Reference Figure 2The inner walls on both sides of the mounting frame 1 are provided with auxiliary sealing grooves 12, and the outer walls of the first door and window 2 and the second door and window 3 are fixedly connected with auxiliary sealing plates 17. The auxiliary sealing plates 17 are adapted to the auxiliary sealing grooves 12. When the windows are closed, the auxiliary sealing plates 17 on both sides of the first door and window 2 and the second door and window 3 engage with the auxiliary sealing grooves 12 to seal and prevent rainwater and dust from entering. The outer wall of the main sealing plate 10 is fixedly installed with sealing strips 11, which facilitates the improvement of the sealing performance between the main sealing plate 10 and the main sealing groove 13.

[0024] The implementation principle of a sealing structure for doors and windows in this application embodiment is as follows: By installing the mounting frame 1 to a suitable position, the first door / window 2 and the second door / window 3 are moved, causing the main sealing plate 10 and the main sealing groove 13 on the first door / window 2 and the second door / window 3 to move towards each other. At the same time, by pulling the handle 8, the handle 8 drives the fixing plate 5 to retract. After the main sealing plate 10 and the main sealing groove 13 are locked and sealed, the pull on the handle 8 is released, causing the springs 6 on both sides to release potential energy and drive the support plate 7 to rebound, thereby causing the fixing plate 5 to rebound and engage with the main sealing plate. The fixing groove 9 on the 10 engages to fix the main sealing plate 10, thus completing the fixation between the first door / window 2 and the second door / window 3. At this time, the main sealing plate 10 and the main sealing groove 13 engage to seal the auxiliary sealing plates 17 on both sides of the first door / window 2 and the second door / window 3 and the auxiliary sealing grooves 12 on both sides of the mounting frame 1, thereby improving the sealing performance of the doors and windows and preventing the intrusion of rainwater and dust. At the same time, the fixing plate 5 and the fixing groove 9 are sealed to a certain extent, further improving the sealing effect of the main sealing plate 10 and the main sealing groove 13, and greatly increasing the sealing performance of the device.
