DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] Referring to Figures 1-4 , the present utility model provides a technical solution: a steel soundproof window with a high sound insulation amount, including a steel window frame 1. Four hinges 2 are respectively hinged on the front and back of the steel window frame 1. One side of two of the front hinges 2 is fixedly connected to a first inner window sash 3, and one side of the other two front hinges 2 is fixedly connected to a third inner window sash 5. One side of two of the back hinges 2 is fixedly connected to a third outer window sash 6, and one side of the other two back hinges 2 is fixedly connected to a first outer window sash 8. A fixing rod 10 is fixedly connected inside the steel window frame 1, and a rotating rod 11 is rotatably connected to the surface of the fixing rod 10. By setting the rotating rod 11, it is convenient to open the window according to the lever principle. A first telescopic rod 12 and a second telescopic rod 14 are slidably connected inside the rotating rod 11.

[0022] Wherein, one side of the first inner window sash 3 close to the first outer window sash 8 is fixedly connected to a first mounting block 13, and one end of the first telescopic rod 12 is rotatably connected inside the first mounting block 13.

[0023] Wherein, one side of the third outer window sash 6 close to the third inner window sash 5 is fixedly connected to a second mounting block 15, and one end of the second telescopic rod 14 is rotatably connected inside the second mounting block 15.

[0024] Wherein, two sound-absorbing louvers 9 are fixedly connected inside the steel window frame 1. By setting the sound-absorbing louvers 9, noise reduction treatment is carried out on the sound, achieving reduction or even isolation of noise pollution to the environment. The lower end surfaces of the two sound-absorbing louvers 9 are both fixedly connected to a bellows protective cover 16.

[0025] Wherein, the two bellows protective covers 16 are fixedly installed inside the steel window frame 1, and an installation opening is provided at the center of the two bellows protective covers 16. The surface of the rotating rod 11 is fixedly connected inside the installation opening.

[0026] Wherein, a second inner window sash 4 is fixedly installed on the front of the steel window frame 1, and a second outer window sash 7 is fixedly installed on the back of the steel window frame 1.

[0027] The working principle of the present utility model: When in use, when the user pulls open the first inner window sash 3, the angle of the rotating rod 11 changes, thereby pushing the third outer window sash 6 to flip outwards. At the same time, the first telescopic rod 12 and the second telescopic rod 14 are forced to extend outwards, further pushing the flip of the third outer window sash 6. The wind direction forms an S-shaped flowing wind direction in the soundproof window. After noise reduction treatment by the sound-absorbing louvers 9, the present device makes the process of air convection ventilation through the sound-absorbing louvers 9 during the window-opening process fast, simple, time-saving and labor-saving.
