Description

Technical Field

[0001] This utility model relates to the field of thermally broken aluminum frame technology, and more specifically, to a thermally broken aluminum sealing frame. Background Technology

[0002] Thermally broken aluminum windows and doors are increasingly favored as a type of thermal insulation building material. Their use represents a close integration of technology and daily life. However, common thermally broken aluminum windows are assembled from an outer frame, a sub-frame, and an opening frame. When closed, gaps exist between these three components, allowing outside water to enter the window frame and then seep into the room. Currently, sealing is mostly achieved by installing sealing strips. Existing products typically use sealing strips between the opening frame and the sub-frame, but there is an installation gap between the outer frame and the sub-frame, making it impossible to install sealing strips. Furthermore, a water accumulation channel is formed between the two, which easily leads to water accumulation. Water from the outside can easily seep into the room through the gaps between the outer frame and the sub-frame. Therefore, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0003] This utility model provides a thermally broken aluminum sealing frame, which aims to improve the problem that there is an installation gap between the outer frame and the sub-frame, making it impossible to install a sealing strip. In addition, a water accumulation groove is formed between the two, which easily accumulates water, and water from the outside can easily seep into the room from the gap between the outer frame and the sub-frame.

[0004] To achieve the above objectives, this utility model provides a thermally broken aluminum sealing frame, the specific technical solution of which is as follows:

[0005] A thermally broken aluminum sealing frame includes an outer frame fixed to a wall, a sub-frame inside the outer frame, an opening fan frame on the sub-frame, a first sealing strip on the outer side of the opening fan frame, a first inclined surface on the outer side of the outer frame that cooperates with the first sealing strip, and a second inclined surface on the outer side of the sub-frame that cooperates with the first sealing strip.

[0006] When the opening fan frame is closed, it abuts against the outer frame and the sub-frame. At this time, the first sealing strip on the opening fan frame fits tightly against the first inclined surface on the outer frame and the second inclined surface on the sub-frame. Thus, the first sealing strip seals the gaps between the opening fan frame and the outer frame, as well as between the opening fan frame and the sub-frame.

[0007] In one embodiment, the first sealing strip includes a first sealing part and a second sealing part. When the opening fan frame is closed, the first sealing part is tightly fitted together with the first inclined surface, thereby sealing the gap between the outer frame and the opening fan frame. At the same time, the second sealing part is tightly fitted together with the second inclined surface, thereby sealing the gap between the sub-frame and the opening fan frame.

[0008] In one embodiment, the interior of the opening fan frame is provided with an overlapping plate, and the inner side of the sub-frame is provided with a second sealing strip that cooperates with the overlapping plate. When the opening fan frame is closed, the overlapping plate can fit tightly with the second sealing strip, thereby sealing the gap between the sub-frame and the opening fan frame.

[0009] In one embodiment, two second sealing strips are provided, so that when the open sash is closed, both second sealing strips can fit tightly together with the overlapping plate.

[0010] In one embodiment, the outer side of the overlapping plate is provided with a corrugated pattern, which can compress the second sealing strip when the opening fan frame is closed.

[0011] The beneficial effects of this embodiment are:

[0012] 1. A first sealing strip is provided on the outer side of the opening fan frame, a first inclined surface that cooperates with the first sealing strip is provided on the outer side of the outer frame, and a second inclined surface that cooperates with the first sealing strip is provided on the outer side of the sub-frame. When the opening fan frame is closed, the opening fan frame abuts against the outer frame and the sub-frame. At this time, the first sealing strip on the opening fan frame is tightly fitted with the first inclined surface on the outer frame and the second inclined surface on the sub-frame. Thus, the first sealing strip seals the gaps between the opening fan frame and the outer frame, as well as between the opening fan frame and the sub-frame, preventing external water from penetrating. At the same time, because the outer frame has the first inclined surface and the sub-frame has the second inclined surface, external water flows down along the inclined surface and will not accumulate, further preventing water from penetrating inward. The entire structure has good sealing performance and plays a good waterproof role.

[0013] 2. An overlapping plate is installed inside the opening sash frame. The length of the overlapping plate is twice that of the existing one. A second sealing strip is installed on the inner side of the sub-frame to cooperate with the overlapping plate. There are two second sealing strips. When the opening sash frame is closed, the overlapping plate can fit tightly with the two second sealing strips, thereby sealing the gap between the sub-frame and the opening sash frame. Because the length of the overlapping plate is longer, the contact area between the overlapping plate and the second sealing strip is increased, thereby strengthening the sealing effect and preventing water from seeping into the room from the inside of the sub-frame and the opening sash frame, thus achieving a good sealing and waterproof function.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] Please see Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides a thermally broken aluminum sealing frame, including an outer frame 100 fixed to the wall, a sub-frame 200 fixed inside the outer frame 100 by screws, the sub-frame 200 is used to install window sash, and an opening sash frame 300 is hinged on the sub-frame 200, the opening sash frame 300 can be opened or closed on the sub-frame 200.

[0035] Please see Figure 2 , Figure 5 and Figure 7 A first sealing strip 400 is provided on the outer side of the opening fan frame 300, a first inclined surface 110 that cooperates with the first sealing strip 400 is provided on the outer side of the outer frame 100, and a second inclined surface 210 that cooperates with the first sealing strip 400 is provided on the outer side of the sub-frame 200. When the opening fan frame 300 is closed, the opening fan frame 300 abuts against the outer frame 100 and the sub-frame 200. At this time, the first sealing strip 400 on the opening fan frame 300 is tightly fitted together with the first inclined surface 110 on the outer frame 100 and the second inclined surface 210 on the sub-frame 200, thereby sealing the gaps between the opening fan frame 300 and the outer frame 100 and between the opening fan frame 300 and the sub-frame 200.

[0036] Please see Figure 1 , Figure 6 , Figure 7 and Figure 10 Preferably, the first sealing strip 400 includes a first sealing part 410 and a second sealing part 420. When the opening fan frame 300 is closed, the first sealing part 410 is tightly fitted together with the first inclined surface 110, thereby sealing the gap between the outer frame 100 and the opening fan frame 300. At the same time, the second sealing part 420 is tightly fitted together with the second inclined surface 210, thereby sealing the gap between the sub-frame 200 and the opening fan frame 300.

[0037] Please see Figure 1 , Figure 6 and Figure 7 The first sealing strip 400 seals the gaps between the opening fan frame 300 and the outer frame 100, as well as between the opening fan frame 300 and the sub-frame 200, preventing external water from penetrating. At the same time, since the outer frame 100 is provided with the first inclined surface 110 and the sub-frame 200 is provided with the second inclined surface 210, external water flows down along the inclined surface and will not accumulate, further preventing water from penetrating into the interior. The entire structure has good sealing performance and plays a good waterproof role.

[0038] Please see Figure 1 , Figure 3 , Figure 8 and Figure 9 It should be noted that an overlapping plate 310 is provided inside the opening fan frame 300, and a second sealing strip 500 that cooperates with the overlapping plate 310 is provided on the inner side of the sub-frame 200. The existing overlapping portion is generally 5mm-6mm, while the overlapping plate 310 of this application is 10mm-15mm long, which is 1-2 times the traditional length. The overall length of the overlapping plate 310 is increased, and the number of sealing strips is increased, thus the sealing effect is better. Preferably, a corrugated pattern is provided on the outer side of the overlapping plate 310. When the opening fan frame 300 is closed, the corrugated pattern can compress the second sealing strip 500. This design increases the contact area between the second sealing strip 500 and the overlapping plate 310, resulting in a better sealing effect and stronger waterproof performance. When the opening fan frame 300 is closed, the overlapping plate 310 can fit tightly against the second sealing strip 500, thus sealing the gap between the sub-frame 200 and the opening fan frame 300. It should be noted that there are two second sealing strips 500, whereas traditionally only one sealing element is used. Increasing the number of sealing strips improves the sealing effect. When the opening fan frame 300 is closed, both second sealing strips 500 can fit tightly against the overlapping plate 310.
