Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a double-layer aluminum door and window with windproof and noise reduction functions. Background Technology

[0002] Double-glazed aluminum doors and windows refer to door and window products made of aluminum alloy with a double-layered glass structure. They are widely used in family bedrooms, living rooms, balconies and other areas.

[0003] Currently, existing double-layer aluminum doors and windows (such as patent publication number: CN215292106U) disclose a door and window structure that, by setting up a railing that can move up and down, allows for free adjustment of the railing's height, adapting to different window installation heights and resident heights. At the same time, by moving the railing upwards, it is easy to adjust the first connecting component to fix the relative position of the window body and window frame, thus eliminating the problem of inconvenience when opening the window outwards when the railing is indoors.

[0004] In the aforementioned patents, double-layer aluminum doors and windows mostly have an inner and outer two-layer sealing structure. With long-term use, the sealing strips are prone to aging, hardening, and cracking, resulting in a decrease in sealing performance. In addition, the gap between the two window frames is sometimes sealed only by the rough edges, resulting in poor windproof and noise reduction effects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-layer aluminum door and window with windproof and noise reduction functions. It solves the technical problems that double-layer aluminum doors and windows mostly have an inner and outer two-layer sealing structure, and the sealing strips are prone to aging, hardening, and cracking after long-term use, resulting in a decline in sealing performance. In addition, some gaps between the two window frames are only sealed with rough edges, resulting in poor windproof and noise reduction effects.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-layer aluminum door and window with windproof and noise reduction functions includes a frame body and a window body. One end of the window body is connected to the frame body through a bearing. A partition strip is provided on the inner side of the frame body. The window body also includes:

[0008] A partition assembly is disposed on the side of the window body. The partition assembly includes an annular rubber strip and sound-absorbing cotton. The sound-absorbing cotton has a multi-layer stacked structure, and the annular rubber strip is connected to the sound-absorbing cotton.

[0009] Preferably, one side of the partition strip has a groove structure, and the partition strip is made of metal.

[0010] A knob is provided at the side end of the window body, and a bevel gear is fixedly installed at the end of the knob.

[0011] Preferably, a drive screw is provided at both ends of the window body, and each drive screw is connected to a knob;

[0012] Each of the drive screws has a sleeve rotatably mounted on its surface, and the thread helix angle of the drive screw and the sleeve is less than the friction angle;

[0013] Each of the sleeves is fixedly mounted with a guide slide plate at its top end, and each of the guide slide plates is fixedly mounted with a friction block at its top end. Each of the friction blocks has a trapezoidal structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, the rotating window body drives the annular rubber strip to reset and align with the side end of the partition strip. The annular rubber strip is inserted into the side end of the partition strip for sealing. The window body squeezes the annular rubber strip so that it engages and bends at the side end of the partition strip, effectively blocking airflow from entering through the gap and achieving windproof function. Sound-absorbing cotton is installed at the side end of the window body and at the connection end between the frame body and the window body to absorb noise transmitted from the window gap and achieve noise reduction.

[0016] In this utility model, an arc-shaped slot is provided on the inner side of the frame body, and the friction block is a trapezoidal structure. The friction block is inserted into the slot to generate a pre-tightening force on the frame body and the window body, so that the frame body and the window body fit together more tightly. At the same time, the horizontal insertion structure increases the stress points at both ends of the window body, ensuring the structural strength of the window body. Attached Figure Description

[0023] This application provides a double-layer aluminum window with windproof and noise reduction functions. It effectively solves the problems of double-layer aluminum windows, which are mostly sealed with inner and outer layers. Under long-term use, the sealing strips are prone to aging, hardening, and cracking, resulting in a decline in sealing performance. In addition, some gaps between the two window panels are only sealed with rough edges, resulting in poor windproof and noise reduction effects. The rotating window body drives the annular sealing strip to reset and align with the side end of the partition strip. The annular sealing strip is inserted into the side end of the partition strip for sealing. The window body squeezes the annular sealing strip so that it engages and bends at the side end of the partition strip, effectively blocking airflow from entering through the gap and achieving windproof function. Sound-absorbing cotton is installed at the side end of the window body and the connection end between the frame body and the window body to absorb noise transmitted from the window gaps and achieve noise reduction. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problems that double-layer aluminum doors and windows mostly have an inner and outer two-layer sealing structure, and that the sealing strips are prone to aging, hardening, and cracking after long-term use, resulting in a decrease in sealing performance. In addition, some gaps between the two window frames are only sealed with rough edges, resulting in poor windproof and noise reduction effects. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a double-layer aluminum door and window with windproof and noise reduction functions, including a frame body 11 and a window body 12. One end of the window body 12 is connected to the frame body 11 through a bearing. A partition strip 13 is provided on the inner side of the frame body 11. By pushing the window body 12, the window body 12 can rotate around the end connected to the frame body 11, and the rotating window body 12 engages with the frame body 11.

[0026] The partition assembly is located on the side of the window body 12. The partition assembly includes an annular rubber strip 14 and sound-absorbing cotton 15. The sound-absorbing cotton 15 has a multi-layer stacked structure. The annular rubber strip 14 is connected to the sound-absorbing cotton 15. At the same time, the rotating window body 12 drives the annular rubber strip 14 to reset. The annular rubber strip 14 is made of elastic material and has a semi-arc structure. The window body 12 drives the annular rubber strip 14 to connect with the side end of the partition strip 13. The annular rubber strip 14 is inserted into the side end of the partition strip 13 for sealing. The window body 12 is fixed by rotating the handle on the side of the window body 12. The sound-absorbing cotton 15 is set on the side of the window body 12 and at the connection end of the frame body 11 and the window body 12 to absorb noise transmitted through the gaps.

[0027] One side of the partition strip 13 has a groove structure. The partition strip 13 is made of metal and is rigid as a whole. The window body 12 moves the annular rubber strip 14 to squeeze the side end of the partition strip 13, so that the annular rubber strip 14 engages and bends at the side end of the partition strip 13.

[0028] A knob 21 is provided on the side end of the window body 12. A bevel gear is fixedly installed at the end of the knob 21. By rotating the knob 21, the knob 21 can drive two drive screws 16 to rotate simultaneously through the bevel gear.

[0029] A drive screw 16 is provided at both ends of the window body 12. Each drive screw 16 is connected to the knob 21. The drive screw 16 rotating in the forward direction is connected to the sleeve 17. The drive screw 16 rotates inside the sleeve 17 and generates a thrust on the sleeve 17, allowing the sleeve 17 to slide inside the window body 12.

[0030] Each drive screw 16 has a sleeve 17 rotatably mounted on its surface. The thread helix angle of the drive screw 16 and the sleeve 17 is less than the friction angle. When the sleeve 17 stops rotating, the drive screw 16 and the sleeve 17 can lock themselves to fix the position of the guide slide plate 18.

[0031] Each sleeve 17 has a guide slide plate 18 fixedly installed at its top end, and each guide slide plate 18 has a friction block 19 fixedly installed at its top end. Each friction block 19 has a trapezoidal structure. The sliding sleeve 17 drives the guide slide plate 18 to slide on the side of the window body 12. At the same time, the friction block 19 is installed at the top end of the guide slide plate 18. The guide slide plate 18 drives the friction block 19 to insert into the inside of the frame body 11. The inside of the frame body 11 is provided with an arc-shaped groove. Since the friction block 19 has a trapezoidal structure, the friction block 19 inserts into the groove, generating a pre-tightening force on the frame body 11 and the window body 12, so that the frame body 11 and the window body 12 fit more tightly. At the same time, the horizontal insertion structure increases the stress points at both ends of the window body 12, ensuring the structural strength of the window body 12.

[0032] Working principle:

[0033] In the first step, the frame body 11 and the window body 12 are connected by a bearing. When the window needs to be opened, the window body 12 is pushed and rotates around the bearing end connected to the frame body 11 to open the window. When closing, the window body 12 is pushed in the opposite direction and rotates around the bearing and gradually approaches the frame body 11 until they are connected.

[0034] A partition component is installed on the side of the window body 12. The annular rubber strip 14 is a semi-circular elastic material structure that connects with the multi-layer stacked sound-absorbing cotton 15. When the window is closed, the rotating window body 12 drives the annular rubber strip 14 to reset and connect with the side end of the partition strip 13. The annular rubber strip 14 is inserted into the side end of the partition strip 13 for sealing. The window body 12 squeezes the annular rubber strip 14 so that it engages and bends at the side end of the partition strip 13, effectively blocking airflow from entering through the gap and achieving windproof function. Sound-absorbing cotton 15 is installed on the side of the window body 12 and at the connection end between the frame body 11 and the window body 12. The porous structure of the sound-absorbing cotton 15 absorbs noise transmitted from the window gap by absorbing, reflecting and scattering sound, thus achieving noise reduction.

[0035] The second step involves installing a knob 21 at the side end of the window body 12, with a bevel gear fixed at its end. Rotating the knob 21 drives two drive screws 16 to rotate simultaneously via the bevel gear transmission. The drive screws 16 are connected to the sleeve 17. The forward-rotating drive screws 16 exert a thrust on the sleeve 17, causing the sleeve 17 to slide inside the window body 12. Since the thread helix angle of the drive screws 16 and the sleeve 17 is less than the friction angle, the two can lock themselves when the sleeve 17 stops rotating.

[0036] A guide slide plate 18 is fixed at the top of the sleeve 17. A trapezoidal friction block 19 is installed at the top of the guide slide plate 18. The sliding sleeve 17 drives the guide slide plate 18 to slide on the side of the window body 12. The guide slide plate 18 then drives the friction block 19 to insert into the arc-shaped slot inside the frame body 11. The cooperation between the trapezoidal friction block 19 and the slot generates a pre-tightening force on the frame body 11 and the window body 12, making them fit more tightly. At the same time, this horizontal insertion structure increases the stress points at both ends of the window body 12, improving the overall structural strength of the window.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
