[0016] As a preferred embodiment of the present invention, the bottom support beam, side plate protective beam, top limiting beam, protective plate and baffle are all made of high-strength aluminum alloy.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. The cleaning components located on the bottom sides of the first and second doors allow for simultaneous opening and closing of the device without the need for separate cleaning, making it convenient to use and saving cleaning time. During use, pulling the second door pushes the guide wheels at the bottom of the walking block to move within the guide rail. The guide wheels cause the cleaning components to slide along the guide rail, allowing them to engage with the second slide rail. As the walking block slides along the second slide rail, it pushes the cleaning blocks at its ends, causing the first cleaning brushes on both sides of the cleaning block to clean the bottom and sidewalls of the second slide rail, thus removing accumulated dust. The second cleaning brushes further improve the cleaning effect by removing dust accumulated inside the guide rail, preventing bacteria and dust from accumulating and effectively avoiding interference with door sliding due to excessive internal dust accumulation. The cleaned dust is then pushed out of the device via the second exit rail, preventing dust buildup and further improving the cleaning effect.

[0019] 2. By pulling the second stop door, the top pulley moves inside the second slide groove, and the bottom pulley moves inside the second slide rail. This helps reduce friction between the devices, reduces resistance, facilitates the operation of the device, and reduces the noise of pushing and pulling. At the same time, when the second stop door slides to the end, the side of the protective plate drives the limiting plate into the second limiting groove. The shock-absorbing pad reduces the sound of the collision between the protective plate and the side plate protective beam. A vacuum cavity is left between the first glass window and the second glass window. The sealing strip not only seals the vacuum cavity but also protects the first and second glass windows. The vacuum helps to block the transmission of sound and reduce noise. With the action of the pad and the shock-absorbing pad, the sound generated by the device due to vibration can be reduced.

[0020] 3. Through the first and second magnetic blocks, the magnetic force enables the two rubber pads to come into close contact, greatly improving the sealing effect of the door leaf. It can not only prevent wind but also prevent sound from spreading through the gap between the first and second door stops. The door frame of the device is made of high-strength aluminum alloy, which enhances the sturdiness and service life of the device. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This invention provides, for example Figures 1-11 The high-strength aluminum alloy door and window with sound insulation and noise reduction is shown, including an outer frame, an inner sash, and a cleaning component 6. The outer frame includes a bottom support beam 1, side panel protective beams 2, and a top limiting beam 3. The inner sash includes a first door stop 4 and a second door stop 5. The bottom support beam 1 supports the first door stop 4 and the second door stop 5. There are two side panel protective beams 2, which are symmetrically distributed at the top of both ends of the bottom support beam 1. The top limiting beam 3 is fixedly connected to the top of the two side panel protective beams 2 respectively. The bottom support beam 1, the two side panel protective beams 2, and the top limiting beam 3 form a U-shaped structure. The first door stop 4 and the second door stop 5 are both located inside the outer frame and are slidably connected to the outer frame, which facilitates pushing and pulling the first door stop 4 and the second door stop 5 to open or close the device. The bottom sides of the first door stop 4 and the second door stop 5 are provided with cleaning components 6, which can clean the device at the same time as pushing and pulling to open or close it, without the need for separate cleaning, which is convenient to use and helps to save cleaning time.

[0037] The inner side of the side panel protective beam 2 is provided with a first limiting groove 21 that mates with the second stop door 5 and a second limiting groove 22 that mates with the first stop door 4, thereby allowing the side panel protective beam 2 to engage with the first stop door 4 and the second stop door 5, which helps to improve the sealing effect of the device. The inner side of the top limiting beam 3 is provided with a first sliding groove that mates with the first stop door 4 and a second sliding groove that mates with the second stop door 5, which facilitates the limiting of the inner fan and improves the stability of the device. The first stop door 4 and the second stop door 5 have the same structure. The door 5 includes a protective plate 51, a baffle 56, a first glass window 57, and a second glass window 58. Limiting plates 52 are fixedly connected to both sides of the protective plate 51. Shock-absorbing pads are fixedly connected to the outer side of the limiting plates 52, and the limiting plates 52 cooperate with the first limiting groove 21. The top of the protective plate 51 is provided with a top pulley 53 that cooperates with the second sliding groove, and the bottom of the protective plate 51 is provided with a bottom protrusion 54. The side of the bottom protrusion 54 is provided with a bottom pulley 55 that cooperates with the second sliding rail 12, which helps to reduce resistance.

[0038] The bottom support beam 1 has a first slide rail 11 that cooperates with the first gate 4 and a second slide rail 12 that cooperates with the second gate 5. The inner bottom walls of the first slide rail 11 and the second slide rail 12 are provided with guide rails. The cleaning component 6 includes a hinge block 61 that is fixedly connected to the first gate 4 or the second gate 5. A connecting rod 62 is hinged to the end of the hinge block 61. A traveling block 63 is hinged to the end of the connecting rod 62 away from the hinge block 61. The traveling block 63 cooperates with the first slide rail 11 or the second slide rail 12. A cleaning block 64 for cleaning the first slide rail 11 or the second slide rail 12 is fixedly connected to the end of the traveling block 63 away from the connecting rod 62. A guide wheel 66 that cooperates with the guide rail is rotatably connected to the bottom of the traveling block 63.

[0039] Specifically, in use, this device moves by pulling the second stop gate 5. The bottom protrusion 54 of the protective plate 51 slides inside the second slide rail 12, and the top of the protective plate 51 slides inside the second slide groove, thus limiting the movement of the second stop gate 5 and improving the stability of the device. Furthermore, the top pulley 53 travels inside the second slide groove, and the bottom pulley 55 travels inside the second slide rail 12, which helps reduce friction between the components, reduces resistance, facilitates the operation of the device, and reduces pushing and pulling noise. The second door 5 drives the hinge block 61 to move, the hinge block 61 pushes the connecting rod 62 to move, the connecting rod 62 drives the walking block 63 to move, thereby pushing the guide wheel 66 at the bottom of the walking block 63 to move inside the guide rail. The guide wheel 66 can drive the cleaning component 6 to slide along the direction of the guide rail, so that the cleaning component 6 can cooperate with the second slide rail 12. When the second door 5 slides to the end, the side of the protective plate 51 drives the limiting plate 52 to enter the second limiting groove 22. The shock-absorbing pad can reduce the sound of the collision between the protective plate 51 and the side plate protective beam 2.

[0040] The cleaning block 64 is equipped with first cleaning brushes on both sides and a second cleaning brush at the bottom. The first cleaning brushes contact the side and bottom walls of the first slide rail 11 or the second slide rail 12, and the second cleaning brushes contact the side and bottom walls of the guide rail. While the traveling block 63 slides along the trajectory of the second slide rail 12, the traveling block 63 pushes the cleaning block 64 at its end to move, so that the first cleaning brushes on both sides of the cleaning block 64 clean the bottom and side walls of the second slide rail 12, thereby cleaning the dust accumulated inside the second slide rail 12. The second cleaning brush cleans the dust accumulated inside the guide rail, which greatly improves the cleaning effect, prevents bacteria and dust from hiding, and effectively avoids the door sliding being affected by too much dust accumulated inside.

[0041] like Figure 8 As shown, both sides of the walking block 63 are rotatably connected to walking wheels 65. The walking wheels 65 cooperate with the first slide rail 11 or the second slide rail 12. While the walking block 63 is moving, the walking wheels 65 contact the bottom wall of the second slide rail 12, thereby supporting the cleaning component 6, which helps to reduce the resistance of the cleaning component 6 and facilitates the operation of the device.

[0042] like Figure 7As shown, both ends of the first slide rail 11 are provided with a first outlet rail 111 connected to the first slide rail 11, and both ends of the second slide rail 12 are provided with a second outlet rail 121 connected to the second slide rail 12. Both the first outlet rail 111 and the second outlet rail 121 are arc-shaped and open outward. When the second gate 5 slides, when the cleaning component 6 slides to the second outlet rail 121, the guide wheel 66 drives the walking block 63 to rotate along the bending direction of the guide rail, thereby driving the connecting rod 62 to rotate. The connecting rod 62 is hinged to the hinge block 61. The connecting rod 62 has a certain length so that the cleaning component 6 does not affect the sliding of the second gate 5 while rotating, thereby pushing the dust cleaned inside through the second outlet rail 121 to the device, avoiding the accumulation of dust inside, and further improving the cleaning effect.

[0043] A further optimization of the above embodiment is that baffles 56 are provided on both the front and rear sides of the protective plate 51. The baffles 56 and the protective plate 51 are detachably connected by screws, which facilitates the disassembly and assembly of the device. The interior of the protective plate 51 is provided with a slot that cooperates with the first glass window 57 and the second glass window 58. The sides of the first glass window 57 and the second glass window 58 are fixedly connected with pads 59. The pads 59 are located inside the slots, thereby fixing and protecting the first glass window 57 and the second glass window 58. The pads 59 can also dampen the first glass window 57 and the second glass window 58, which helps to reduce the noise caused by vibration.

[0044] In a further optimization of the above embodiment, a sealing strip 50 is fixedly connected to the inner side of the protective plate 51 at the position between the first glass window 57 and the second glass window 58. The sealing strip 50 is in contact with the first glass window 57 and the second glass window 58, and a vacuum cavity is left between the first glass window 57 and the second glass window 58. The sealing strip 50 can not only seal the vacuum cavity, but also protect the first glass window 57 and the second glass window 58. The vacuum helps to block the transmission of sound and can further reduce noise.

[0045] like Figure 1 , Figure 9 and 11 As shown, anti-vibration pads 561 are fixedly connected to the inner sides of both baffles 56. The anti-vibration pads 561 are in contact with the first glass window 57 or the second glass window 58, which can prevent damage to the first glass window 57 or the second glass window 58 during the installation of the baffles 56, and can also reduce vibration and noise of the device.

[0046] In a further optimization of the above embodiment, a first magnetic block 411 is fixedly connected to the side of the first gate 4 near the second gate 5, and a second magnetic block 511 is fixedly connected to the right side of the second gate 5 near the first gate 4. The first magnetic block 411 and the second magnetic block 511 are magnetically attracted to each other, and a rubber pad 412 is fixedly connected to the opposite side of the first magnetic block 411 and the second magnetic block 511.

[0047] Specifically, when the door needs to be closed, the user pushes the first door stop 4 and the second door stop 5 to slide to both ends, so that the first magnetic block 411 on the side of the first door stop 4 gets close to the second magnetic block 511 on the side of the second door stop 5. Under the action of magnetic force, the two rubber pads 412 can be brought into close contact, which greatly improves the sealing effect of the door. It can not only prevent wind but also prevent sound from spreading through the gap between the first door stop 4 and the second door stop 5.

[0048] To enhance the robustness and service life of the device, the bottom support beam 1, side plate protective beam 2, top limiting beam 3, protective plate 51 and baffle 56 are all made of high-strength aluminum alloy, which can greatly improve the robustness of the device.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
