Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to an adaptive sealing thermal break door and window. Background Technology

[0002] Thermally broken aluminum windows and doors use insulated aluminum profiles and double-glazed glass, offering energy-saving, sound insulation, noise reduction, dustproofing, and waterproofing functions. The thermal conductivity coefficient (K-value) of thermally broken aluminum windows and doors is below 3W / ㎡·K, reducing heat loss by half compared to ordinary windows and doors, lowering heating costs by approximately 30%, and providing sound insulation of over 29 decibels. They also exhibit excellent water tightness and air tightness.

[0003] Most existing thermally broken aluminum windows and doors have the sealing strips directly fixed to the window sash or frame sidewalls, which cannot self-seal when the window sash is opened and closed, affecting the airtightness of the thermally broken aluminum windows and doors and reducing their airtightness.

[0004] To address the aforementioned issues, an improved adaptive sealing thermal break door / window is now designed. Utility Model Content

The first fixed frame, the first connecting pipe, and the sealing airbag are interconnected.

[0009] As a further embodiment of this utility model: the switching mechanism includes a second fixed frame, which is installed at the bottom of the mounting box. A second piston block is slidably connected to the inner wall of the second fixed frame. A spring for pushing the second piston block upward is installed at the lower end of the second piston block, and the lower end of the spring is installed at the bottom of the second fixed frame. A second sliding rod is installed at the upper end of the second piston block, and a rack is vertically installed at the upper end of the second sliding rod through the second fixed frame. Sliding sealing rings are installed at the sliding connection of the second sliding rod and the second fixed frame, as well as on the side wall of the second piston block. A second... Two connecting pipes are connected. One end of the second connecting pipe near the second fixed frame is positioned above the second piston block.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4 In this embodiment of the present invention, the adaptive sealing thermal break window includes a window frame 1, a window sash 2 is provided inside the window frame 1, one side of the window sash 2 is rotatably connected to the window frame 1 by a hinge, an installation box 5 is installed on the side of the window sash 2 away from the hinge, the installation box 5 and the hinge are both located on the same side of the window frame 1 and the window sash 2, a groove 8 is provided on the side wall of the window sash 2, a sealing airbag 9 for sealing the gap between the window frame 1 and the window sash 2 is installed inside the groove 8, an adaptive sealing mechanism for inflating and deflating the sealing airbag 9 is provided at the rotatable connection between the window frame 1 and the window sash 2, and an opening and closing mechanism for the user to open and close the window sash 2 is provided on the installation box 5.

[0024] The adaptive sealing mechanism includes several first fixed frames 3. The first fixed frames 3 are horizontally arranged on the side of the window sash 2 and the window frame 1 near the mounting box 5. One end of the first fixed frame 3 is rotatably connected to the window sash 2 via a hinge. A first piston block 10 is slidably connected to the inner wall of the first fixed frame 3. A first slide rod 4 is installed on the side of the first piston block 10 away from the rotating end of the first fixed frame 3 and the window sash 2. The end of the first slide rod 4 away from the first piston block 10 passes through the first fixed frame 3 and is rotatably connected to the window frame 1 via a hinge. Sliding sealing rings are installed on the sliding connection of the first slide rod 4, the first fixed frame 3, and the side wall of the first piston block 10. A first connecting pipe 11 is installed on the side wall of the first fixed frame 3 near the first slide rod 4. The end of the first connecting pipe 11 near the first fixed frame 3 is located on the side of the first piston block 10 near the first slide rod 4. The output end of the first connecting pipe 11 passes through the window sash 2 and is connected to the sealing airbag 9. The first fixed frame 3, the first connecting pipe 11, and the sealing airbag 9 are interconnected.

[0025] When the window sash 2 is opened, the window sash 2 causes the first fixed frame 3 and the first sliding rod 4 to swing. The first sliding rod 4 pushes the first piston block 10 to move along the inner wall of the first fixed frame 3, so that the first piston block 10 moves towards the bottom of the first fixed frame 3. This draws the air inside the sealing airbag 9 into the first fixed frame 3 through the first connecting pipe 11, causing the sealing airbag 9 to contract and making it easier to open the window sash 2.

[0026] When the window sash 2 is closed, the window sash 2 causes the first fixed frame 3 and the first sliding rod 4 to swing. The first sliding rod 4 pulls the first piston block 10 to move along the inner wall of the first fixed frame 3, causing the first piston block 10 to move to one side of the first sliding rod 4. This allows the air inside the first fixed frame 3 to be transported to the sealing airbag 9 through the first connecting pipe 11, causing the sealing airbag 9 to expand and seal the gap between the window frame 1 and the window sash 2.

[0027] The switching mechanism includes a second fixed frame 19, which is installed at the bottom of the mounting box 5. A second piston block 17 is slidably connected to the inner wall of the second fixed frame 19. A spring 18 for pushing the second piston block 17 upward is installed at the lower end of the second piston block 17. The lower end of the spring 18 is installed at the bottom of the second fixed frame 19. A second slide rod 15 is installed at the upper end of the second piston block 17. A rack 13 is vertically installed through the second fixed frame 19 at the upper end of the second slide rod 15. Sliding sealing rings are installed at the sliding connection of the second slide rod 15 and the second fixed frame 19, as well as on the side wall of the second piston block 17. A second connecting pipe 16 is installed at the upper end of the side wall of the second fixed frame 19. One end of the connecting pipe 16 near the second fixed frame 19 is positioned above the second piston block 17. The other end of the second connecting pipe 16 away from the second fixed frame 19 passes through the mounting box 5 and the window sash 2 and connects to the sealing airbag 9. The sealing airbag 9, the second connecting pipe 16, and the mounting box 5 are interconnected. Inside the mounting box 5 near the upper end of the second slide rod 15, there is a gear 12 that works with the rack 13. The gear 12 meshes with the lower end of the rack 13. A rotating rod 14 is installed at the center of the gear 12. Both ends of the rotating rod 14 pass through the side wall of the mounting box 5 and are fitted with a rotating frame 7 for driving the rack 13 to rotate. The rotating rod 14 is rotatably connected to the side wall of the mounting box 5. A handle 6 is vertically installed at the lower end of the rotating frame 7.

[0028] In use, first lift handle 6 upwards. Handle 6 drives rotating frame 7 to rotate, rotating frame 7 drives rotating rod 14 to rotate, rotating rod 14 drives gear 12 to rotate, gear 12 drives rack 13 to move downwards, rack 13 pushes second slide rod 15 to move, second slide rod 15 pushes second piston block 17 to move, and compresses spring 18. Thus, some air inside sealing airbag 9 is drawn into mounting box 5 through second connecting pipe 16, reducing the degree of expansion and sealing of sealing airbag 9. After releasing handle 6, under the action of elasticity, spring 18 pushes second piston block 17 to move upwards, and air is delivered into sealing airbag 9 through second connecting pipe 16, and handle 6 returns to the vertical position.

[0029] The working principle of adaptive sealing thermal break doors and windows:

[0030] When opening window sash 2, first lift handle 6 upwards. Handle 6 drives rotating bracket 7 to rotate. Rotating bracket 7 drives rotating rod 14 to rotate. Rotating rod 14 drives gear 12 to rotate. Gear 12 drives rack 13 to move downwards. Rack 13 pushes second slide rod 15 to move. Second slide rod 15 pushes second piston block 17 to move and compresses spring 18. Thus, through second connecting pipe 16, some air inside sealing airbag 9 is drawn into mounting box 5, reducing the degree of expansion and sealing of sealing airbag 9.

[0031] Then the window sash 2 is opened, and the window sash 2 causes the first fixed frame 3 and the first sliding rod 4 to swing. The first sliding rod 4 pushes the first piston block 10 to move along the inner wall of the first fixed frame 3, so that the first piston block 10 moves to the bottom of the first fixed frame 3, thereby drawing the air inside the sealing airbag 9 into the first fixed frame 3 through the first connecting pipe 11, causing the sealing airbag 9 to contract, making it easier to open the window sash 2.

[0032] After the handle 6 is released, the spring 18 pushes the second piston block 17 upward under the action of the elastic force, and delivers air into the sealed airbag 9 through the second connecting pipe 16, and resets the handle 6 to the vertical position.

[0033] When closing window sash 2, first lift handle 6 upwards. Handle 6 drives rotating bracket 7 to rotate, rotating bracket 7 drives rotating rod 14 to rotate, rotating rod 14 drives gear 12 to rotate, gear 12 drives rack 13 to move downwards, rack 13 pushes second slide rod 15 to move, second slide rod 15 pushes second piston block 17 to move, and compresses spring 18, thereby drawing some air from inside sealing airbag 9 into mounting box 5 through second connecting pipe 16, reducing the degree of expansion and sealing of sealing airbag 9.

[0034] The window sash 2 causes the first fixed frame 3 and the first sliding rod 4 to swing. The first sliding rod 4 pulls the first piston block 10 to move along the inner wall of the first fixed frame 3, causing the first piston block 10 to move to one side of the first sliding rod 4. This allows the air inside the first fixed frame 3 to be transported to the sealing airbag 9 through the first connecting pipe 11, causing the sealing airbag 9 to expand and seal the gap between the window frame 1 and the window sash 2.

[0035] After the handle 6 is released, the spring 18 pushes the second piston block 17 upward under the action of the elastic force, and delivers air into the sealed airbag 9 through the second connecting pipe 16, and resets the handle 6 to the vertical position.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
