[0031] like Figure 1-3 As shown, Example 1: A combined noise reduction window frame includes a window frame body 1, and slots 9 are provided on both sides of the front and rear ends of the top of the window frame body 1, and springs 10 are fixedly connected to the upper sides of the inner walls of the slots 9, and blocks 8 are rotatably connected to the tops of the springs 10, and knobs 7 are slidably connected to the inner walls of the blocks 8, and main bevel gears 11 are fixedly connected to the bottom ends of the knobs 7, and auxiliary bevel gears 12 are meshedly connected to the lower sides of the outer walls of the main bevel gears 11, and bidirectional threaded rods 13 are fixedly connected to the left ends of the auxiliary bevel gears 12, and sliders 14 are threadedly connected to the left and right sides of the outer walls of the bidirectional threaded rods 13, and mounting components are provided at the upper and lower ends of the window frame body 1, and a noise reduction window body 2 is fixedly connected to the inner wall of the window frame body 1. The mounting assembly includes a mounting frame 16, a plurality of through holes 17 are provided at the front end of the mounting frame 16, limit blocks 15 are provided on the left and right sides of the inner wall of the mounting frame 16, the opposite ends of the limit blocks 15 are respectively fixedly connected to the opposite ends of the sliders 14, the shape of the through holes 17 matches the limit blocks 15, the outer walls of the clamping blocks 8 are provided on the inner walls of the clamping grooves 9, the left ends of the two-way threaded rods 13 are respectively rotatably connected to the front and rear parts of the left side of the inner wall of the window frame body 1, the top ends of the main bevel gears 11 are respectively rotatably connected to the front and rear parts of the upper side of the inner wall of the window frame body 1, and the outer walls of the sliders 14 are slidably connected to the inner wall of the window frame body 1.

[0032] Specifically, the worker first fixes the installation frame 16 at the upper and lower ends of the window. After the fixing is completed, the limit blocks 15 at the upper and lower ends are inserted into the installation frame 16 through the through holes 17, and then the block 8 and the rotating knob 7 are pulled upward. The knob 7 drives the main bevel gear 11, the auxiliary bevel gear 12, and the two-way threaded rod 13 to rotate. The two-way threaded rod 13 drives the sliders 14 and the limit blocks 15 on both sides to move to both sides. Move the limit blocks 15 to a farther distance from the through holes 17, and the window frame body 1 can be fixed on the installation frame 16. After the installation is completed, the block 8 is released and the block 8 is inserted into the slot 9 by the spring 10 to limit the knob 7 to prevent the window frame body 1 from falling off the installation frame 16. During disassembly, the worker only needs to rotate the knob 7 in the opposite direction and move the limit block 15 to the position of the through hole 17 to remove the window frame body 1 from the installation frame 16. As a result, the worker does not need to spend a lot of time to disassemble the noise reduction window body 2, which makes it convenient for the worker to quickly disassemble the window frame body 1 from the installation frame 16, thereby improving work efficiency.

[0033] like Figure 1 , 4 As shown, Example 2: The noise reduction window body 2 includes an outer glass layer 3, a hollow layer 4, a sound insulation cotton layer 5 and an inner glass layer 6, the bottom end of the outer glass layer 3 is fixedly connected to the top end of the hollow layer 4, the bottom end of the hollow layer 4 is fixedly connected to the top end of the sound insulation cotton layer 5, the bottom end of the sound insulation cotton layer 5 is fixedly connected to the top end of the inner glass layer 6, the top end of the outer glass layer 3 is set to face the outdoors, and the bottom end of the inner glass layer 6 is set to face the indoors.

[0034] Specifically, when the window frame body 1 is in use, the outer glass layer 3 can isolate external noise, the hollow layer 4 forms an air layer inside the noise reduction window body 2, which can help reduce the conduction of noise, and the sound insulation cotton layer 5 can absorb the incoming sound wave energy and reduce the reflection and propagation of noise in the window frame. The inner glass layer 6 is similar to the outer glass layer 3 and also plays a role in isolating noise. The two layers of glass can further reduce the permeability of noise. By isolating and absorbing noise multiple times, the impact of external noise on the indoor environment is reduced.

[0035] Working principle: First, the worker fixes the installation frame 16 at the upper and lower ends of the window. After the fixation is completed, the limit blocks 15 at the upper and lower ends are inserted into the installation frame 16 through the through holes 17, and then the block 8 and the rotating knob 7 are pulled upward. The knob 7 drives the main bevel gear 11 to rotate, and the main bevel gear 11 drives the secondary bevel gear 12 to rotate. The secondary bevel gear 12 drives the two-way threaded rod 13 to rotate, and the two-way threaded rod 13 drives the sliders 14 and the limit blocks 15 on both sides to move to both sides. Move the limit blocks 15 to a farther distance from the through holes 17, and then the window frame body 1 can be fixed on the installation frame 16. After the installation is completed, release the block 8, and use the spring 10 to clamp the block 8 into the slot 9 to limit the knob 7 to prevent the window frame body 1 from falling off the installation frame 16. When disassembling, the worker only needs to rotate the knob 7 in the opposite direction to move the limit blocks 15 is moved to the position of the through hole 17, and the window frame body 1 can be removed from the installation frame 16, so that workers do not need to spend a lot of time to remove the noise reduction window body 2, which makes it convenient for workers to quickly remove the window frame body 1 from the installation frame 16, thereby improving work efficiency. When the window frame body 1 is in use, the outer glass layer 3 can isolate external noise, and the hollow layer 4 forms an air layer inside the noise reduction window body 2, which can help reduce the conduction of noise. The sound insulation cotton layer 5 can absorb the incoming sound wave energy and reduce the reflection and propagation of noise in the window frame. The inner glass layer 6 is similar to the outer glass layer 3 and also plays a role in isolating noise. The two layers of glass can further reduce the permeability of noise. By isolating and absorbing noise multiple times, the impact of external noise on the indoor environment is reduced.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
