[0017] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Figures 1 - 3 Shown is the overall structure schematic diagram of a plastic-steel window with high sound insulation of the present utility model. Please refer to Figures 1 - 3 , A plastic-steel window with high sound insulation in this embodiment includes a main frame 100 fixed on a wall. A concave slot 110 is provided on one side of the main frame 100 and along the circumferential direction of the main frame 100, and the concave slot 110 is through at both ends. A C-shaped sealing strip 200 is fixedly inserted and embedded inside the concave slot 110, and the opening of the C-shaped sealing strip 200 faces outward. A window frame 300 matching the main frame 100 is hinged on one side of the main frame 100. The inner side of the window frame 300 has soundproof glass 310. The four sides of the side of the window frame 300 facing the main frame 100 have convex strips 320 corresponding to the concave slot 110 and simultaneously fitting and matching with the C-shaped sealing strip 200. The inner cavities of the main frame 100 and the window frame 300 also have sound-absorbing fillers 400.

[0021] The cross-section of the rib 320 is a trapezoidal structure, and the inner side of the C-shaped sealing strip 200 facing the rib 320 is also a trapezoidal structure. At the same time, the inclined angles on both sides of the rib 320 are smaller than the inclined angles on both sides of the inner surface of the C-shaped sealing strip 200. Such a structural design enables the rib 320 to form a closer contact when embedded in the inner side of the C-shaped sealing strip 200, avoiding the occurrence of gaps between the rib 320 and the C-shaped sealing strip 200 due to improper closing of the window, and effectively preventing the entry of noise; moreover, this "curved" sealing has a better sound insulation effect compared to straight sealing; in addition, the inside of the rib 320 is a hollow structure, which can further reduce the transmission of sound. There are also hollow cavities 210 on both sides inside the C-shaped sealing strip 200, and the hollow cavities 210 correspond to the inclined surface parts on both sides of the C-shaped sealing strip 200 respectively. It can be understood that when the rib 320 is embedded in the inner side of the C-shaped sealing strip 200, the hollow cavities 210 can form more elastic avoidance spaces for the rib 320, thereby further increasing the contact surface and the sound insulation and sealing effect between the rib 320 and the C-shaped sealing strip 200.

[0022] The sound-absorbing filler 400 is a sound-absorbing foam material. In this embodiment, the sound-absorbing filler 400 can adopt common sound-absorbing foam materials on the market. This kind of sound-absorbing foam material is a porous polymer material, and its internal structure is similar to that of a sponge, having good sound-absorbing properties, which further improves the sound insulation of the entire frame. In addition, this plastic-steel window makes clever use of the central chamber structure inside the plastic-steel window, and injects sound-absorbing foam material into the chamber, which neither affects the weight of the window body nor has a sound insulation effect.

[0023] Furthermore, a plurality of injection holes communicating with the inner chambers of the main frame 100 and the window frame 300 are provided on the outer sides of the main frame 100 and the window frame 300, and a plug 600 is provided inside the injection holes. During actual production, the sound-absorbing foam fluid can be injected into the inner chambers of the main frame 100 and the window frame 300 through the injection holes by means of later drilling or reservation, and then sealed tightly with the plug 600 after completion, which is simple and effective.

[0024] Furthermore, sound-absorbing membranes 500 are respectively attached to the sides of the sound-insulating glass 310 facing the outdoors and the indoors. Here, the sound-absorbing membranes 500 in this embodiment can adopt common weather-resistant sound-absorbing membranes on the market, which have the characteristics of being colorless and transparent, having the function of absorbing and degrading low-frequency noise, and sound-absorbing membranes 500 are attached to both the inner and outer surfaces of the glass, further improving the sound insulation effect of the plastic-steel window, which is simple and practical.

[0025] In summary, for the plastic-steel window with high sound insulation of the present embodiment, during use, by designing the cross-section of the rib 320 as a trapezoidal structure, and the inner side of the C-shaped sealing strip 200 facing the rib 320 is also a trapezoidal structure. At the same time, the inclined angles on both sides of the rib 320 are smaller than the inclined angles on both sides of the inner surface of the C-shaped sealing strip 200. In this way, when the rib 320 is embedded inside the C-shaped sealing strip 200, a closer contact can be formed, avoiding the occurrence of gaps between the rib 320 and the C-shaped sealing strip 200 due to the improper closing of the window, and effectively preventing the entry of noise. Moreover, this "curved" sealing has a better sound insulation effect compared to the straight surface sealing. In addition, the inside of the rib 320 is a hollow structure, which can further reduce the transmission of sound. At the same time, sound-absorbing fillers 400 are injected into the inner chambers of the main frame 100 and the window frame 300, further improving the sound insulation of the entire frame.

[0026] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
