Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and more specifically, it relates to a sealing device for aluminum alloy doors and windows. Background Technology

[0002] The sealing performance of aluminum alloy doors and windows directly affects the sound insulation, heat insulation and waterproofing of buildings. In the existing technology, the gap between the window and the outer frame is often difficult to completely eliminate. Especially under the action of temperature difference or wind pressure, the thermal expansion and contraction of metal profiles will cause the gap to expand further. This structural defect means that there are still air infiltration channels when the doors and windows are closed, which not only reduces the energy-saving effect, but also makes it easy to have water leakage problems in windy and rainy weather, seriously affecting the comfort of use and building energy efficiency.

[0003] From the perspective of actual usage needs, traditional sealing structures still have the problem of aging and deformation after long-term use. The sealing strip is prone to hardening and cracking under repeated opening and closing and ultraviolet radiation, losing its elasticity and compensation ability. On the other hand, simple rubber seals are difficult to meet both durability and sealing pressure requirements. Especially in high-rise buildings, when encountering strong winds, even slight deformation of the door and window frames can directly lead to sealing failure, resulting in obvious wind howling and airflow infiltration.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sealing device for aluminum alloy doors and windows, which has the following beneficial effects:

[0017] 1. This aluminum alloy door and window sealing device significantly improves the sealing performance of doors and windows through its innovative airbag structure. The airbag adopts a frame-shaped design that fits tightly into the connecting groove. After inflation, it can adaptively fill various irregular gaps between the window and the outer frame, effectively solving the sealing failure problem caused by thermal expansion and contraction or deformation of traditional sealing strips.

[0018] 2. The inflation mechanism adopts a pneumatically driven design, which achieves automatic opening and closing through the synergistic effect of air pressure and spring. During inflation, the sealing block automatically disengages from the through hole to form an airflow channel. After inflation is completed, it automatically resets and seals, ensuring both inflation efficiency and airtightness.

[0019] 3. The sealing mechanism utilizes a dual adjustment method of threaded drive and spring preload to precisely control the sealing pressure according to actual needs. The knob with anti-slip strip design makes operation more convenient and reliable. The entire device, through the elastic compensation characteristics of the airbag, can not only adapt to the deformation of doors and windows during daily opening and closing, but also maintain a stable sealing effect under conditions of strong wind pressure or temperature changes, significantly improving the sound insulation, heat insulation, and waterproof performance of doors and windows. The threaded engagement structure of the transmission sleeve and the mounting sleeve allows for adjustable sealing pressure, extending the service life of the sealing components and solving the pain point of easy aging and failure of traditional sealing devices.

An inflation mechanism is provided on the outer wall of the airbag 4. The inflation mechanism includes a mounting sleeve 5, a mounting plate 6, an air outlet 7, a sealing sleeve 8, a sealing block 9, and a through hole 10. The mounting sleeve 5 is connected to the outer wall of the airbag 4 and fixedly connected to the outer frame 1. The mounting plate 6 abuts against the bottom surface of the mounting sleeve 5. Multiple sets of air outlets 7 are provided on the outer wall of the mounting plate 6. The sealing sleeve 8 is fixed to the inner wall of the mounting sleeve 5. The sealing block 9 is provided with... Multiple sets of sealing blocks 9 are fixed on the top surface of the mounting plate 6. Multiple sets of through holes 10 are distributed on the outer wall of the cover 8 and are slidably connected to multiple sets of sealing blocks 9. A sealing mechanism is provided inside the mounting sleeve 5. The sealing mechanism includes a slide rod 11, a slide sleeve 12, a transmission sleeve 13, a knob 14 and a compression spring 15. The slide rod 11 is rotatably mounted on the top surface of the mounting plate 6 and is rotatably connected to the cover 8. The slide sleeve 12 slides on the outer wall of the slide rod 11. The transmission sleeve 13 is fixed on the outside of the slide sleeve 12. The knob 14 is fixed at the top of the slide rod 11. The two ends of the compression spring 15 are respectively fixedly connected to the knob 14 and the slide sleeve 12.

[0030] The airbag 4 is frame-shaped and installed in the connecting groove 3. The frame structure of 4 achieves a complete seal with the gaps in the doors and windows.

[0031] A sealing ring 16 is installed on the inner side of the mounting plate 6. The sealing ring 16 is slidably connected to the mounting sleeve 5. The sealing ring 16 enhances the airtightness between 5 and 6 to prevent air leakage.

[0032] The top surface of the sealing block 9 and the outer sides of the multiple through holes 10 are all provided with rounded corners. The rounded corner design of 9 and 10 reduces the frictional resistance during relative movement.

[0033] The upper half of the slide rod 11 is set as a polygon and is slidably connected to the slide sleeve 12. The polygonal structure of 11 and 12 form an anti-rotation guide mechanism.

[0034] The outer wall of the transmission sleeve 13 and the inner wall of the mounting sleeve 5 are threaded together, and the pressure adjustment function is achieved through the threaded connection between 13 and 5.

[0035] The outer wall of the knob 14 is fixed with anti-slip strips 17. Multiple sets of anti-slip strips 17 are provided to increase the operating friction of the knob 14 and facilitate the application of force.

[0036] The top of the mounting sleeve 5 is fixed with a connecting tube 18, and the outside of the connecting tube 18 is provided with external threads. The external thread structure of 18 enables quick connection with the inflation device.

[0037] In this embodiment, during use, the connecting pipe 18 is threadedly connected to the external inflation pipe, and the mounting sleeve 5 is inflated by the external inflation device. When the inflation pressure is greater than the preset force of the compression spring 15, the air pressure pushes multiple sets of sealing blocks 9 to slide along the through hole 10. At the same time, the multiple sets of sealing blocks 9 push the mounting plate 6 to disengage from the mounting sleeve 5. The mounting plate 6 slides along the sliding sleeve 12 via the sliding rod 11. The sliding rod 11 drives the knob 14 to compress the compression spring 15. When the multiple sets of sealing blocks 9 disengage from the through hole 10, a flow space is formed. Subsequently, the airflow is injected into the airbag 4 through multiple sets of air outlets 7 for inflation. After completion, the compression spring 15 resets and pushes the knob 14 to drive the sliding rod 11 to slide along the sliding sleeve 12 and drive the mounting plate 6 to reset and adhere to the inner wall of the mounting sleeve 5. At the same time, the multiple sets of sealing blocks 9 slide into the through hole 10 for sealing. The airbag 4 seals the gap between the window 2 and the outer frame 1.

[0038] More specifically, when it is necessary to adjust the sealing of the mounting sleeve 5, turn the knob 14 to drive the slide rod 11 to rotate, the slide rod 11 to drive the slide sleeve 12 to rotate, the slide sleeve 12 to drive the transmission sleeve 13 to rotate and engage with the inner wall of the mounting sleeve 5 through the thread. The transmission sleeve 13 drives the slide sleeve 12 to slide along the slide rod 11 and compress the compression spring 15, pressing the compression spring 15 so that the mounting plate 6 is pressed against the inner wall of the mounting sleeve 5 for sealing.

[0039] In summary, during use or operation of the overall equipment: When in use, the connecting pipe 18 is threadedly connected to the external inflation pipe. Inflation is then performed on the mounting sleeve 5 via an external inflation device. When the inflation pressure exceeds the preset force of the compression spring 15, the air pressure pushes multiple sealing blocks 9 to slide along the through hole 10. Simultaneously, the multiple sealing blocks 9 push the mounting plate 6 away from the mounting sleeve 5. The mounting plate 6 slides along the sliding sleeve 12 via the sliding rod 11. The sliding rod 11 drives the knob 14 to compress the compression spring 15. When the multiple sealing blocks 9 disengage from the through hole 10, a flow space is formed. Subsequently, airflow is injected into the airbag 4 through multiple air outlets 7 for inflation. After inflation, the compression spring 15 resets, pushing the knob 14 to slide the sliding rod 11 along the sliding sleeve 12 and causing the mounting plate 6 to reset and adhere to the inner wall of the mounting sleeve 5. Simultaneously, the multiple sealing blocks 9 slide into the through hole 10 for sealing, and the airbag 4 seals the gap between the window 2 and the outer frame 1.

[0040] When it is necessary to adjust the sealing of the mounting sleeve 5, turn the knob 14 to drive the slide rod 11 to rotate, the slide rod 11 to drive the slide sleeve 12 to rotate, the slide sleeve 12 to drive the transmission sleeve 13 to rotate and engage with the inner wall of the mounting sleeve 5 through the thread. The transmission sleeve 13 drives the slide sleeve 12 to slide along the slide rod 11 and compress the compression spring 15. The compression spring 15 is pressed so that the mounting plate 6 is pressed against the inner wall of the mounting sleeve 5 to seal.
