Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and more specifically, to a waterproof structure for an aluminum alloy inward casement window. Background Technology

[0002] Most aluminum alloy inward-opening casement windows on the market have drainage holes directly located in the outer frame groove, or simply recessed and sloped to create drainage holes. Their waterproofing structure is simple, and the products are almost identical. In strong winds and rain, water can easily seep into the interior through the sealing strip between the window sash and frame, resulting in inadequate waterproofing. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waterproof structure for an aluminum alloy inward-opening casement window.

[0004] The objective of this utility model is achieved through the following technical solution: A waterproof structure for an aluminum alloy inward-opening casement window includes a first sealing mechanism disposed on the window frame and a second sealing mechanism disposed on the window sash. When the window sash is closed, the second sealing mechanism is sealed to the first sealing mechanism to achieve multi-layer sealing.

[0005] Furthermore, in this utility model, the first sealing mechanism includes a first sealing part, an equal pressure sealing strip, and an outdoor sealing strip arranged sequentially at intervals on the window frame, and the equal pressure sealing strip is provided with a second sealing part and a third sealing part; when the window sash is in the closed state, the second sealing mechanism is simultaneously sealed and connected with the first sealing part, the second sealing part, the third sealing part, and the outdoor sealing strip.

[0006] Furthermore, in this utility model, the second sealing mechanism includes an indoor sealing strip, a heat insulation strip, and a fourth sealing part arranged sequentially and at intervals on the window sash. The heat insulation strip is provided with a first inner sealing strip and a second inner sealing strip at intervals. When the window sash is closed, the indoor sealing strip abuts against the first sealing part, the first inner sealing strip abuts against the second sealing part, the second inner sealing strip abuts against the third sealing part, and the fourth sealing part abuts against the outdoor sealing strip.

[0007] Furthermore, in this invention, the second sealing part is an inclined surface.

[0008] Furthermore, in this utility model, a drainage hole is provided on the window frame near the outdoor sealing strip.

[0009] The beneficial effects of this utility model are: This utility model provides a waterproof structure for an aluminum alloy inward-opening casement window. By installing a first sealing mechanism on the window frame and a second sealing mechanism on the window sash, when the window sash is closed, the second sealing mechanism is sealed to the first sealing mechanism, which can form a multi-layer seal between the window sash and the window frame, thereby improving the waterproof effect.

[0012] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0013] Please see Figure 1 and Figure 2 This utility model provides a technical solution: A waterproof structure for an aluminum alloy inward-opening casement window includes a first sealing mechanism installed on the window frame 101 and a second sealing mechanism installed on the window sash 201. When the window sash 201 is closed, the second sealing mechanism is sealed to the first sealing mechanism to achieve multi-layer sealing between the window sash 201 and the window frame 101, thereby improving the waterproof effect.

[0014] Specifically, such as Figure 1As shown, in this embodiment, the first sealing mechanism includes a first sealing part 301, an equal pressure sealing strip 302, and an outdoor sealing strip 303, which are sequentially and spaced apart on the window frame 101. The first sealing part 301 is located near the indoor side, and the outdoor sealing strip 303 is located near the outdoor side. A slot is provided at a corresponding position on the window frame 101, and the outdoor sealing strip 303 is engaged in the slot. The equal pressure sealing strip 302 is provided with a second sealing part 304 and a third sealing part 305. When the window sash 201 is in the closed state, the second sealing mechanism is simultaneously sealed and connected to the first sealing part 301, the second sealing part 304, the third sealing part 305, and the outdoor sealing strip 303.

[0015] Specifically, such as Figure 1 As shown, in this embodiment, the second sealing mechanism includes an indoor sealing strip 401, a heat insulation strip 402, and a fourth sealing part 403 arranged sequentially and at intervals on the window sash 201. The indoor sealing strip 401 is located near the indoor side, and the fourth sealing part 403 is located near the outdoor side. A slot is provided at a corresponding position on the window sash 201, and the indoor sealing strip 401 is engaged in the slot. A first inner sealing strip 404 and a second inner sealing strip 405 are installed at intervals on the heat insulation strip 402.
