Description

Technical Field

[0001] This utility model relates to the field of door and window sealing technology, and more specifically, to door and window sealing components. Background Technology

[0002] Door and window sealing components refer to a series of sealing devices used during door and window installation to ensure that doors and windows are tightly closed and to prevent air, moisture, dust and noise from entering or leaving. Their main function is to improve the heat insulation, sound insulation and wind pressure resistance of doors and windows, thereby improving the overall use effect and comfort of doors and windows.

[0003] Traditional sealing components mostly use fixed rubber strips for compression sealing. When the doors and windows are closed, the sealing is achieved solely by the pre-compression of the rubber strip. However, in actual use, window frame deformation, such as thermal expansion and contraction of aluminum alloy profiles due to temperature differences, or installation errors can easily increase the sealing gap, leading to increased air leakage.

[0004] Therefore, we made improvements and proposed a door and window sealing component. Utility Model Content

[0035] Please refer to Figure 1-5 The door and window sealing assembly includes: a frame 1; sealing assemblies 2 are provided on both sides of the inner cavity of the frame 1; window frames 3 are installed on both sides of the front side of the frame 1; windows 4 are installed in the inner cavity of the window frames 3; handles 5 are installed on one side of the front side of the window frames 3; and sealing grooves 6 are opened on the top and bottom of the rear side of the window frames 3.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The sealing assembly 2 includes two push rods 201, both of which are movably connected to the front side of the inner cavity of the frame 1. A first inclined plate 202 is fixedly installed on the rear side of the push rods 201, and a first spring 203 is fixedly installed on the rear side of the first inclined plate 202. A second inclined plate 204 is movably connected to the top and bottom of the rear side of the first inclined plate 202. A third inclined plate 205 is movably connected to the front side of the opposite side of the two second inclined plates 204. A fixing plate 206 is fixedly installed between the front sides of the four third inclined plates 205. A sealing gasket 207 is installed on the top and bottom of the front side of the fixing plate 206, and multiple second springs 208 are fixedly installed on the top and bottom of the rear side of the fixing plate 206. The side of the first spring 203 closest to the frame 1 is fixedly connected to the frame 1, and the side of the second spring 208 closest to the frame 1 is fixedly connected to the frame 1. The surface of the push rod 201 is slidably connected to the inner cavity of the sealing gasket 207. The sealing gasket 207 cooperates with the sealing groove 6. First limiting blocks 209 are fixedly installed on both sides of the first inclined plate 202, and the first limiting blocks 209 are slidably connected to the inner cavity of the frame 1. A sliding block 210 is fixedly installed on the rear side of the second inclined plate 204, and a sliding rod 211 is slidably connected to the inner cavity of the sliding block 210. Support blocks 212 are fixedly installed on the top and bottom of the sliding rod 211, and the side of the support block 212 closest to the frame 1 is fixedly connected to the frame 1. Two second limiting blocks 213 are fixedly installed on the top and bottom of the fixed plate 206, and the second limiting blocks 213 are slidably connected to the inner cavity of the frame 1. When window 4 is closed, the rear side of window frame 3 pushes the push rod 201 backward, causing the push rod 201 to drive the first inclined plate 202 to compress the first spring 203. As the first inclined plate 202 moves backward, it pushes the second inclined plate 204 to unfold to both sides through the hinge points at the top and bottom. The second inclined plate 204 then pushes the third inclined plate 205 forward, forming a three-stage transmission. The third inclined plate 205 drives the fixed plate 206 forward, while the second spring 208 is compressed and stores energy. The fixed plate 206 pushes the sealing gasket 207 into the sealing groove 6. When the sealing groove 6 is completely filled, the sealing gasket 207 is deformed by compression and fits tightly against the groove wall, blocking the airflow and water flow channels. If the window frame deforms and causes the sealing groove 6 to shift, the first spring 203 and the second spring 208 release their elastic force, pushing the fixing plate 206 to adaptively adjust its displacement, ensuring that the sealing gasket 207 is continuously compressed. After the window 4 is opened, the push rod 201 loses its compressive force, the first spring 203 and the second spring 208 reset, driving the fixing plate 206 to move, and the sealing gasket 207 exits from the sealing groove 6, avoiding long-term compression that leads to elastic decay.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
