Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a noise reduction structure for door and window frames and the door and window frames thereof. Background Technology

[0002] With the increasing number of high-rise buildings in cities and the growing severity of noise pollution, the sound insulation and noise reduction performance of doors and windows has become an important indicator when purchasing them.

[0003] Chinese Patent No. CN215718322U discloses a noise reduction device for door and window frames. The noise reduction device includes a window frame, on which a rotating shaft is rotatably mounted. The axis of rotation of the rotating shaft is parallel to the plane of the window frame. A connecting plate is slidably mounted on the window frame. The sliding direction of the connecting plate is perpendicular to the axis of rotation of the rotating shaft. Sound-absorbing cotton is wound around the rotating shaft. One end of the sound-absorbing cotton is mounted on the rotating shaft, and the other end is mounted on the connecting plate. A winding component is provided on the rotating shaft to drive the rotating shaft to wind up the sound-absorbing cotton. A fixing component is provided on the window frame to fix the connecting plate. The sound-absorbing cotton has the effect of reducing noise.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: the rotating shaft is equipped with a winding sleeve for driving the rotating shaft to wind up the sound-absorbing cotton. The sound-absorbing cotton usually uses its internal tiny pores and channels to reduce noise. Winding up the sound-absorbing cotton by the rotating shaft and the winding sleeve will limit the thickness of the sound-absorbing cotton and limit the noise reduction effect. At the same time, the winding process will compress the sound-absorbing cotton, thereby damaging the internal structure of the sound-absorbing cotton and weakening the noise reduction effect.

Since adjacent mounting backplates 22 are rotatably connected by connecting plates 25, several mounting backplates 22 can be rolled up using a structure similar to bamboo slips, thus allowing the mounting backplates 22 to be wound and stored, while simultaneously storing the sound-absorbing cotton 3. Protective plates 23 are fixedly connected to both ends of the mounting backplates 22. The protective plates 23 and the mounting backplates 22 can protect the sound-absorbing cotton, preventing compression of the sound-absorbing cotton 3 during winding. In addition, compared with the prior art that uses a rotating shaft and winding sleeve for storage, this application uses a winding storage method similar to bamboo slips and sets up a protective structure for the sound-absorbing cotton, thereby allowing the use of thicker sound-absorbing cotton 3, ensuring the noise reduction effect of the noise reduction structure, and having better practicality.

[0029] A binding strap 6 is fixedly connected to one side of the mounting plate 11, and a binding strap 7 is fixedly connected to the other side of the mounting plate 11.

The snap-fit ​​block 8 can support the lower end of the installation mechanism 2, which helps to improve the stability of the installation mechanism 2 when it is installed on the door and window frame body 1 in the unfolded state.

[0034] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0035] The mounting mechanism 2 includes a fixing strip 21 and several mounting back plates 22. A single piece of sound-absorbing cotton 3 is fixedly mounted on several mounting back plates 22. Since adjacent mounting back plates 22 are rotatably connected by connecting plates 25, the mounting back plates 22 are rolled up using a structure similar to bamboo slips, allowing for the winding and storage of the mounting back plates 22 and the sound-absorbing cotton 3. Protective plates 23 are fixedly connected to both ends of the mounting back plates 22. The protective plates 23 and the mounting back plates 22 can protect the sound-absorbing cotton and prevent compression of the sound-absorbing cotton 3 during winding. Compared with the prior art that uses a rotating shaft and winding sleeve for storage, this application uses a winding storage method similar to bamboo slips and sets up a protective structure for the sound-absorbing cotton, thus allowing the use of thicker sound-absorbing cotton 3, ensuring the noise reduction effect of the noise reduction structure, and having better practicality. The winding can be completed by using binding strap 1 6 and binding strap 2 7. The mounting mechanism 2 is then bound and fixed to prevent it from coming apart, facilitating the normal use of the window or door. Several snap-fit ​​blocks 8 are fixedly connected to the main body 1 of the window or door frame. Snap-fit ​​rods 26 are fixedly connected to the lower end of the connecting plate 25 at the lower end. The snap-fit ​​blocks 8 and snap-fit ​​rods 26 are positioned one-to-one. Snap-fit ​​slots 9 are provided on the snap-fit ​​blocks 8, and the snap-fit ​​rods 26 are snapped into the slots 9. When the mounting mechanism 2 is unfolded, the snap-fit ​​rods 26 can be snapped onto the snap-fit ​​blocks 8 one by one, while the connecting block 24 is snapped onto the fixing block 10. The connecting block 24 and the fixing block 10 can fix the side end of the mounting mechanism 2, and the snap-fit ​​blocks 8 can support the lower end of the mounting mechanism 2. This improves the stability of the mounting mechanism 2 when it is installed on the main body 1 of the window or door frame in the unfolded state, prevents the mounting mechanism 2 from accidentally falling off the main body 1 of the window or door frame, ensures sound insulation and noise reduction, and enhances the reliability of the device.
