Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to a sound-insulating and noise-reducing aluminum alloy door and window. Background Technology
[0002] Aluminum alloy doors and windows are door and window systems with aluminum alloy frames. According to the opening method, they can be divided into casement doors and windows, double doors and windows, sliding doors and windows, top-hung doors and windows, etc. Because aluminum alloy is used as the frame structure, it has the advantage of good durability.
[0003] Casement windows are connected to the outer frame by a rotating mechanism. To ensure the stability of the rotation, a gap is left between the window and the outer frame, which results in greater noise in the room during use, thus reducing the practicality of the device. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a soundproof and noise-reducing aluminum alloy door and window.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a soundproof and noise-reducing aluminum alloy door and window, including a window frame, a window body rotatably mounted on the window frame, the window body and the window frame being rotatably connected by a hinge, a through groove being opened through the window body, a glass window being fixedly installed in the through groove, a sealant being applied between the glass window and the through groove, sound insulation cotton being installed on the inner bottom wall and inner top wall of the window frame, and a movable component for moving the sound insulation cotton being provided inside the window frame.
[0006] By adopting the above technical solution, when the staff uses the window body, they can open or close the window body through the handle on the window body. During this process, when the staff closes the window body, they can move the sound insulation cotton through the moving component, thereby filling the gap between the window body and the window frame. In this process, the sound insulation cotton reduces indoor noise, thus improving the practicality of the device.
[0007] Furthermore, the inner bottom wall and inner top wall of the window frame are provided with sliding grooves, the sound insulation cotton matches the sliding grooves, and the inner wall of the sliding grooves are symmetrically provided with mounting grooves. The moving component includes a mounting rod that is slidably disposed in the mounting groove and a first spring that is fixedly disposed on the side wall of the mounting rod. The other end of the first spring is fixedly disposed on the inner wall of the mounting groove, and the mounting rod and the sound insulation cotton are fixed to each other.
[0008] By adopting the above technical solution, when the staff closes the window body, the mounting rod slides towards the window body under the action of the first spring, thereby causing the sound insulation cotton to move towards the window body under the action of the mounting rod. This causes the sound insulation cotton to press against the side wall of the window body, thus filling the gap between the window body and the window frame. In this process, the sound insulation cotton reduces indoor noise, thereby improving the practicality of the device.
[0009] Furthermore, a movable groove is provided on the inner wall of both mounting grooves. A movable rod is slidably disposed in the movable groove. Two connecting grooves are provided through the side wall of the movable rod. The connecting grooves are matched with the mounting rod. A fixing groove is provided on the side wall of the mounting rod. The movable rod is matched with the fixing groove. A first inclined surface is provided on the inner wall of the fixing groove. A second spring is fixedly disposed on the side wall of the movable rod. The other end of the second spring is fixedly disposed on the inner wall of the movable groove.
[0010] Furthermore, a drive groove is provided through the inner wall of the moving groove, and a drive component is slidably disposed in the drive groove. A second inclined surface is provided on the edge where the side wall of the moving rod away from the second spring intersects with the side wall near the drive component.
[0011] By adopting the above technical solution, when a worker needs to open the window, the worker slides the drive component, causing it to gradually approach and eventually press against the second inclined surface. This causes the moving rod to slide under the action of the drive component, bringing the inner wall of the connecting groove on the moving rod into contact with the first inclined surface. This causes the mounting rod to slide away from the window body under the action of the moving rod, and consequently, the sound insulation cotton moves away from the window body under the action of the mounting rod. This reduces the probability of the sound insulation cotton obstructing the worker's opening of the window. Subsequently, when the worker closes the window, the worker slides the drive component in the opposite direction, causing the moving rod to return to its original position under the action of the second spring. This causes the mounting rod to slide under the action of the first spring, gradually filling the gap between the window frame and the window body with the sound insulation cotton, thereby improving the window's sound insulation effect.
[0012] Furthermore, a first fixing hole is provided on the inner wall of the drive groove, and a second fixing hole is provided on the side wall of the drive component. A fixing rod is slidably disposed in the first fixing hole, and the fixing rod is slidably connected to the second fixing hole.
[0013] Furthermore, a third spring is fixedly installed on the side wall of the fixing rod, and the other end of the third spring is fixedly installed on the inner wall of the first fixing hole. The end of the fixing rod away from the third spring is provided with a rounded corner.
[0014] By adopting the above technical solution, during the process of the operator sliding the drive component, the distance between the first fixing hole and the second fixing hole gradually decreases until they are directly opposite each other. At this time, under the action of the third spring, one end of the fixing rod slides into the second fixing hole, thereby fixing the drive component and reducing the probability of the fixing rod sliding when subjected to external force, thus improving the stability of the device. In addition, the rounded corners reduce the probability of the fixing rod obstructing the drive component when the operator slides it, thereby improving the stability of the device.
[0015] Furthermore, the sound insulation cotton is made of sponge material.
[0016] By adopting the above technical solution, the sound insulation cotton made of sponge material improves the sound insulation effect of the sound insulation cotton, thereby improving the practicality of the device.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. In this application, when the staff uses the window body, the staff can open or close the window body through the handle on the window body. During this process, when the staff closes the window body, the staff can move the sound insulation cotton through the moving component, so that the sound insulation cotton fills the gap between the window body and the window frame. During this process, the sound insulation cotton reduces indoor noise, thereby improving the practicality of the device.
[0019] 2. In this application, when the staff closes the window body, the mounting rod slides towards the window body under the action of the first spring, thereby causing the sound insulation cotton to move towards the window body under the action of the mounting rod, so that the sound insulation cotton presses against the side wall of the window body, thereby filling the gap between the window body and the window frame. In this process, the sound insulation cotton reduces indoor noise, thereby improving the practicality of the device.
[0020] 3. In this application, when a worker needs to open the window body, the worker slides the drive component, causing it to gradually approach and eventually press against the second inclined surface. This causes the moving rod to slide under the action of the drive component, bringing the inner wall of the connecting groove on the moving rod into contact with the first inclined surface. This causes the mounting rod to slide away from the window body under the action of the moving rod, and consequently, the sound insulation cotton to move away from the window body under the action of the mounting rod. This reduces the probability of the sound insulation cotton obstructing the worker's opening of the window body. Subsequently, when the worker closes the window body, the worker slides the drive component in the opposite direction, causing the moving rod to return to its original position under the action of the second spring. This causes the mounting rod to slide under the action of the first spring, gradually filling the gap between the window frame and the window body with the sound insulation cotton, thereby improving the window's sound insulation effect.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0027] like Figure 1-4 As shown in the illustration, this application discloses a soundproof and noise-reducing aluminum alloy door and window, including a window frame 1, a window body 11, a glass window 12, sound insulation cotton 13, a moving assembly 3, a moving rod 4, a second spring 44, a driving component 5, a fixing rod 6, and a third spring 7. The window frame 1 is a cuboid structure. The window body 11 is rotatably mounted on the window frame 1, and the window body 11 and the window frame 1 are rotatably connected by a hinge. A through groove 2 is provided through the window body 11. The glass window 12 is fixedly installed in the through groove 2, and sealant is applied between the glass window 12 and the through groove 2. Two sound insulation cotton 13s are provided and installed on the inner bottom wall and inner top wall of the window frame 1 to reduce noise.
[0028] When the staff uses the window body 11, they can open or close the window body 11 using the handle on the window body 11. During this process, when the staff closes the window body 11, they can move the sound insulation cotton 13 using the moving component 3, thereby filling the gap between the window body 11 and the window outer frame 1. In this process, the sound insulation cotton 13 reduces indoor noise, thereby improving the practicality of the device.
[0029] The inner bottom and top walls of the window frame 1 are provided with sliding grooves 21, and the sound insulation cotton 13 matches the sliding grooves 21. The inner walls of the sliding grooves 21 are symmetrically provided with mounting grooves 22. A movable component 3 is disposed inside the window frame 1 to move the sound insulation cotton 13. The movable component 3 includes a mounting rod 31 and a first spring 32. The mounting rod 31 is a rectangular rod structure, slidably disposed within the mounting groove 22, and fixed to the sound insulation cotton 13. One end of the first spring 32 is fixedly disposed on the side wall of the mounting rod 31, and the other end is fixedly disposed on the inner wall of the mounting groove 22.
[0030] When the staff closes the window body 11, the mounting rod 31 slides towards the window body 11 under the action of the first spring 32, thereby causing the sound insulation cotton 13 to move towards the window body 11 under the action of the mounting rod 31. This causes the sound insulation cotton 13 to press against the side wall of the window body 11, thus filling the gap between the window body 11 and the window outer frame 1. In this process, the sound insulation cotton 13 reduces indoor noise, thereby improving the practicality of the device.
[0031] The inner walls of the two mounting slots 22 are jointly provided with a movable slot 23. The movable rod 4 is slidably disposed in the movable slot 23. Two connecting slots 41 are provided through the side wall of the movable rod 4. The connecting slots 41 are matched with the mounting rod 31. A fixing slot 42 is provided on the side wall of the mounting rod 31. The movable rod 4 is matched with the fixing slot 42. The inner wall of the fixing slot 42 is provided with a first inclined surface 43. One end of the second spring 44 is fixedly disposed on the side wall of the movable rod 4, and the other end of the second spring 44 is fixedly disposed on the inner wall of the movable slot 23.
[0032] A drive groove 24 is provided through the inner wall of the moving groove 23. The drive member 5 is slidably disposed in the drive groove 24. A second inclined surface 51 is provided on the edge where the side wall of the moving rod 4 away from the second spring 44 intersects with the side wall of the moving rod 4 near the drive member 5.
[0033] When the staff needs to open the window body 11, they slide the drive component 5, causing it to gradually approach and eventually press against the second inclined surface 51. This causes the moving rod 4 to slide under the action of the drive component 5, bringing the inner wall of the connecting groove 41 on the moving rod 4 into contact with the first inclined surface 43. This causes the mounting rod 31 to slide away from the window body 11 under the action of the moving rod 4, and consequently, the sound insulation cotton 13 to move away from the window body 11 under the action of the mounting rod 31. This reduces the probability of the sound insulation cotton 13 obstructing the staff when opening the window body 11. Subsequently, when the staff closes the window body 11, they slide the drive component 5 in the opposite direction, causing the moving rod 4 to return to its original position under the action of the second spring 44. This causes the mounting rod 31 to slide under the action of the first spring 32, filling the gap between the window frame 1 and the window body 11 with the sound insulation cotton 13, thereby improving the window's sound insulation effect.
[0034] A first fixing hole 25 is provided on the inner wall of the drive groove 24, and a second fixing hole 26 is provided on the side wall of the drive component 5. The fixing rod 6 is a round rod structure with its axis horizontal. The fixing rod 6 is slidably disposed in the first fixing hole 25, and the fixing rod 6 is slidably connected to the second fixing hole 26.
[0035] One end of the third spring 7 is fixedly mounted on the side wall of the fixing rod 6, and the other end of the third spring 7 is fixedly mounted on the inner wall of the first fixing hole 25. The end of the fixing rod 6 away from the third spring 7 is provided with a rounded corner.
[0036] As the operator slides the drive component 5, the distance between the first fixing hole 25 and the second fixing hole 26 gradually decreases until they are directly opposite each other. At this time, under the action of the third spring 7, one end of the fixing rod 6 slides into the second fixing hole 26, thereby fixing the drive component 5 and reducing the probability of the fixing rod 6 sliding when subjected to external force, thus improving the stability of the device. In addition, the rounded corners reduce the probability of the fixing rod 6 obstructing the drive component 5 when the operator slides it, thereby improving the stability of the device.
[0037] To improve the practicality of the device, the sound insulation cotton 13 is made of sponge material. The sponge material improves the sound insulation effect of the sound insulation cotton 13, thereby improving the practicality of the device.
[0038] The working principle of the soundproof and noise-reducing aluminum alloy door and window in this embodiment is as follows: When the staff uses the window body 11, the staff can open or close the window body 11 through the handle on the window body 11. During this process, when the staff closes the window body 11, the staff can move the sound insulation cotton 13 through the moving component 3, so that the sound insulation cotton 13 fills the gap between the window body 11 and the window outer frame 1. During this process, the sound insulation cotton 13 reduces the indoor noise, thereby improving the practicality of the device.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
