Description

Technical Field

[0001] This utility model relates to the technical field of door and window materials, specifically to a dustproof and soundproof aluminum profile for doors and windows. Background Technology

[0002] The background technology of aluminum profiles for dustproof and soundproof doors and windows can be summarized as follows: Traditional door and window profiles have significant shortcomings in dealing with noise pollution and dust intrusion. Ordinary aluminum alloy doors and windows, due to their simple structural design and limited sealing performance, cannot meet the dual requirements of modern buildings for sound insulation and noise reduction (especially in traffic arteries and busy urban areas) and dust prevention and cleanliness (such as in medical, laboratory, and high-precision manufacturing environments). Early improvement solutions mostly adopted the addition of rubber sealing strips or simple hollow structures, but these had problems such as narrow sound insulation bands and easy aging and failure of elastic seals. With the advancement of materials science and profile processing technology, modern solutions tend towards composite designs—using multi-cavity structures to block the sound bridge effect, combined with gradient sealing systems (such as EPDM rubber strips and brush seals) to achieve dynamic sealing, and filling the profile with sound-absorbing materials (such as polyurethane foam) to widen the sound insulation band. Some high-end products also use nano-coating technology to enhance surface dust repellency. These technological evolutions have driven the development of aluminum profiles from single enclosure functions to multi-functional integrated designs to meet the needs of green buildings and healthy living environments.

[0003] Application number CN202121233180.X discloses a dustproof and noise-reducing aluminum profile for doors and windows, including the aluminum profile, sound insulation cotton, and a first positioning plate. The aluminum profile and the sound insulation cotton are slidably connected. A support block is slidably connected to the outer side of the end of the sound insulation cotton near the center of the aluminum profile. A positioning block is slidably connected to the outer side of the support block. A connecting block is fixedly connected to the outer side of the end of the support block near the center of the positioning block. Through the arrangement of the sound insulation cotton, support block, positioning block, connecting block, connecting rod, positioning rod, and first spring, when the sound insulation cotton, support block, positioning block, connecting rod, and first spring are used, the noise reduction and sound insulation material can be effectively controlled. In use, the sound insulation cotton is first placed inside the aluminum profile of the door and window. Then, the positioning rod inside the positioning block is pulled, causing the positioning rod to compress the spring. This causes the positioning rod to drive the connecting rod, which in turn pulls the support block to slide inside the positioning block. This allows the support block to fix the sound insulation cotton inside the aluminum profile of the door and window, enhancing the sound insulation effect of the aluminum profile and increasing privacy protection. However, the drawback is that the window constructed by the device does not yet provide convenient opening and closing of the window, thus not improving the ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof and soundproof aluminum profile for doors and windows, which solves the problem that windows constructed with the aforementioned device do not yet provide convenient opening and closing functions, and thus do not improve ease of use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dustproof and soundproof aluminum profile for doors and windows, including a frame assembly. A braking assembly is installed on one side of the bottom of the frame assembly, and a flip-up window assembly is installed on the top of the braking assembly. The flip-up window assembly is set inside the window frame of the frame assembly.

[0007] The flip-up window assembly includes a central rod, which is limited and installed at the other end of the connecting plate. The central rod is also installed inside the aluminum window frame via a reinforcing sleeve. A flip-up window flap is installed in the middle of the central rod via a fixing ring.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a dustproof and soundproof aluminum profile for doors and windows, including a frame assembly 1, a braking assembly 2 installed on one side of the bottom of the frame assembly 1, and a flip-up window assembly 3 installed on the top of the braking assembly 2. The flip-up window assembly 3 is set inside the window frame of the frame assembly 1.

[0026] The flip-up window assembly 3 includes a center rod 301, which is limited at the other end of the connecting plate 204. The center rod 301 is installed inside the aluminum window frame 102 through a reinforcing sleeve rod 302. Meanwhile, a flip-up window flap 304 is installed in the middle of the center rod 301 through a fixing ring 303. The flip-up window flap 304 is limited inside the aluminum window frame 102.

[0027] By installing the flip-up window assembly 3 on the device, the device can be used to merge and open the window by means of the braking assembly 2, making the window more convenient to use.

[0028] The frame assembly 1 includes a mounting bracket 101, an aluminum window frame 102 is fixedly mounted on one side of the top of the mounting bracket 101, and a limiting frame 103 is fixedly mounted on one side of the aluminum window frame 102.

[0029] The braking assembly 2 includes a pneumatic telescopic pump 201, which is fixedly mounted on the top of the mounting bracket 101 via a bracket. A telescopic brake rod 202 is mounted on the top of the pneumatic telescopic pump 201. A connecting plate 204 is connected to the top of the telescopic brake rod 202 via a limiting rod 203. The end of the limiting rod 203 is limited and installed inside the linkage bracket 205. Several connecting plates 204 are connected to the linkage bracket 205 via several limiting rods 203. During the braking control phase, after receiving a control signal, the pneumatic telescopic pump 201 drives the telescopic brake rod 202 to perform vertical reciprocating motion. The linear motion is converted into multi-directional linkage through the hinged limiting rod 203. The linkage bracket 205 constrains the motion trajectory, causing the connecting plate 204 to produce a precise angular deflection.

[0030] The reinforcing sleeve 302 is fixedly installed inside the limiting frame 103. During the window leaf transmission stage, the connecting plate 204 drives the central rod 301 to rotate around the axis of the reinforcing sleeve 302. The fixing ring 303 transmits the torque to the flip window leaf 304. The window leaf rotates 0-90° around the central rod as the axis, and then enters the dynamic sealing stage. When in the open state, the edge of the flip window leaf 304 keeps in sliding contact with the inner wall of the aluminum window frame 102 when it flips.

[0031] The aluminum window frame 102 has several limiting slots 1021 on both sides, and a center rod 301 is installed inside the limiting slots 1021 for limiting.

[0032] The aluminum window frame 102 includes an outer window frame layer 1022. The outer wall of the outer window frame layer 1022 has several sound-absorbing ports 1023. The sound-absorbing ports 1023 are equipped with corresponding sound insulation pads 1024. A reinforcing frame 1025 is fixedly installed inside the sound insulation pads 1024. In order to achieve sound insulation and dust prevention, after external noise enters through the honeycomb sound-absorbing ports 1023, it is absorbed by the porous sound-absorbing cotton sound insulation pads 1024 in multiple frequency bands. The cross reinforcing ribs in the vacuum cavity block the sound wave transmission path. The composite structure of the outer window frame layer 1022 and the reinforcing frame 1025 forms a physical dust barrier.

[0033] This device controls the opening and closing of the tilting window through a pneumatically driven multi-link braking system, and achieves dynamic sealing in conjunction with a composite sound insulation structure. The specific working process is as follows: During the braking control phase, the pneumatic telescopic pump 201 receives a control signal and drives the telescopic brake rod 202 to perform vertical reciprocating motion. The linear motion is converted into multi-directional linkage through the hinged limit rod 203, and the linkage bracket 205 constrains the motion trajectory, causing the connecting plate 204 to produce a precise angular deflection, further realizing the opening and closing effect of the tilting window 304. Then, in the window slat transmission phase, the connecting plate 204 drives the central rod 301 to rotate around the axis of the reinforcing sleeve rod 302. The fixing ring 303 transmits torque to the tilting window 304, and the window slat performs a 0-90° tilting motion around the central rod as the axis. After that, it enters the dynamic sealing phase. When in the open state, the edge of the tilting window 304 rotates with the aluminum profile window. The inner wall of the frame 102 maintains sliding contact, achieving sound insulation and dust prevention. External noise enters through the honeycomb-shaped sound-absorbing port 1023 and is absorbed by the porous sound-absorbing cotton sound insulation pad 1024 in multiple frequency bands. The cross-shaped reinforcing ribs in the vacuum cavity block the sound wave transmission path. The composite structure of the outer layer 1022 of the window frame and the reinforcing frame 1025 forms a physical dust barrier. This device achieves stepless speed adjustment of the window sash through a pneumatic and multi-link combination drive system. The trajectory constraint design of the linkage bracket 205 ensures that the synchronization error of multiple windows is <0.5mm. The interference fit design of the reinforcing sleeve rod 302 and the limiting frame 103, together with the shock-absorbing rubber layer, eliminates resonance leakage. When closed, the window sash and the limiting groove 1021 form a labyrinth-like sealed channel. The honeycomb-shaped sound-absorbing port 1023 achieves a noise reduction coefficient (NRC) of 0.85. The vacuum cavity, together with the cross-shaped reinforcing ribs, achieves an airborne sound insulation Rw ≥42dB.
