Description

Technical Field

[0001] This utility model relates to the field of thermally broken aluminum insulated windows, specifically a thermally broken aluminum insulated window structure. Background Technology

[0002] Thermally broken aluminum windows refer to windows made using thermally broken aluminum profiles as the frame material. The term "thermally broken aluminum" refers to the addition of a non-metallic thermal break strip inside the aluminum alloy frame, achieving a thermal break effect. This design effectively prevents heat transfer between the indoor and outdoor areas, reducing energy consumption and improving living comfort. In existing technology, patent publication number CN 218493426 U discloses a thermally broken aluminum window, including a window frame. The inner wall of the window frame is rotatably connected to the window sash via hinges or latches. A protective component is provided on the inner wall of the window frame, with the protective left hinge acting behind the window sash to isolate it from the outside environment. Although thermal insulation can be achieved through the thermal break strip between the inner and outer aluminum alloy frame panels, in the closed state, due to dimensional errors or installation factors, the window frame and window sash may not fit tightly enough, affecting the thermal insulation effect of the thermally broken aluminum window. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a thermally broken aluminum window structure. The structure uses the thrust generated by the closing of the glass sash frame to drive the air extraction component to work, so that a negative pressure is created between the glass sash frame and the sealing component. Atmospheric pressure is used to make the glass sash frame and the sealing component fit more tightly, thereby improving the airtightness of the thermally broken aluminum window and enhancing its thermal insulation effect. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a thermally broken aluminum window structure, including a thermally broken aluminum window frame, wherein glass sash frames are hinged to both the left and right ends of the thermally broken aluminum window frame, and a sealing mechanism is also included.

[0005] Sealing mechanism: It includes a sliding groove, a hollow sliding plate, a frame, and an air extraction piston. The sliding grooves are respectively set at the rear end of the thermally broken aluminum window frame. The upper end of the sliding groove is longitudinally connected to the sealing sliding groove with elastic limit hollow sliding plates. The front end of the hollow sliding plates is provided with a frame. The front end of the frame is an open structure. The hollow sliding plates are all connected to the frame. The air extraction piston is slidably connected inside the hollow sliding plates. The thrust generated by the closing of the glass sash frame drives the air extraction component to work, so that a negative pressure appears between the glass sash frame and the sealing component. Atmospheric pressure is used to make the glass sash frame and the sealing component fit more tightly, improve the sealing performance of the thermally broken aluminum window, and enhance the thermal insulation effect of the thermally broken aluminum window.

[0006] Furthermore, the sealing mechanism also includes a linkage frame, a large gear, a small gear, and a drive rack plate. The linkage frames are located inside the slide groove. The upper longitudinal plates of the linkage frames pass through the clearance sliding holes on the rear side of the hollow slide plate and are fixedly connected to the suction piston. The lower longitudinal plate of the linkage frame is a rack plate. The large gears are rotatably connected to the lower end of the slide groove through a rotating shaft. The large gears are meshed with the adjacent linkage frames. The outer arc surface of the rotating shaft of the large gear is provided with a small gear. The drive rack plate is longitudinally slidably connected inside the slide groove. The drive rack plate is meshed with the small gear to provide power for the movement of the suction piston.

[0007] Furthermore, the diameter of the large gear is twice the diameter of the small gear, so that the moving speed of the suction piston is twice the moving speed of the hollow slide plate.

[0008] Furthermore, rubber strips are fixedly fitted at both the upper and lower ends of the frame to make the frame fit more tightly with the glass sash frame.

[0009] Furthermore, the hollow slide plate is provided with guide plates on both the left and right sides, and springs are provided between the guide plates and the rear inner wall of the slide groove. Guide posts are provided on the rear inner wall of the slide groove, and the front ends of the guide posts pass through the interior of the springs and slide longitudinally with the guide holes of the guide plates to provide elastic limiting for the hollow slide plate.

[0010] Furthermore, the front surface of the drive rack plate and the front surface of the frame are located in the same vertical plane, ensuring the synchronous movement of the hollow slide plate and the drive rack plate.

[0011] Furthermore, the rear inner wall of the slide is provided with support columns, which are longitudinally slidably connected to the guide holes at the rear end of the drive rack plate, providing guidance and support for the movement of the drive rack plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This thermally broken aluminum window structure has the following advantages:

[0013] The thrust generated when the glass frame closes drives the air extraction component to work, creating negative pressure between the glass frame and the sealing component. Atmospheric pressure is then used to make the glass frame and the sealing component fit more tightly, improving the airtightness of the thermally broken aluminum window and enhancing its thermal insulation effect.

[0019] 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.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a thermally broken aluminum window structure, including a thermally broken aluminum window frame 1. The thermally broken aluminum window frame 1 adopts the thermally broken aluminum window commonly used in the prior art, and is composed of inner and outer aluminum alloy frames and thermal insulation strips. The thermal insulation strips can be made of polyamide or PVC material. Through the thermal insulation strips, heat is blocked from being conducted between the inner and outer aluminum alloy frame plates, thereby improving the thermal insulation effect of the thermally broken aluminum window. Both ends of the thermally broken aluminum window frame 1 are hinged to glass sash frames 2. The glass sash frames 2 are all equipped with glass inside, and also include a sealing mechanism 3.

[0021] Sealing mechanism 3 includes a sliding groove 31, a hollow sliding plate 32, a frame 33, and an air extraction piston 34. The sliding groove 31 is respectively located at the rear end of the thermally broken aluminum window frame 1. Hollow sliding plates 32 with elastic limits are longitudinally slidably connected within the sealing grooves at the upper end of the sliding grooves 31. A frame 33 is provided between the front ends of the hollow sliding plates 32. The front end of the frame 33 has an open structure, and the hollow sliding plates 32 are all connected to the frame 33. An air extraction piston 34 is slidably connected inside each hollow sliding plate 32. Both the hollow sliding plate 32 and the air extraction piston 34 are made of sealing ceramic material. The air extraction piston 34 is a plate-shaped structure that matches the inner cavity of the hollow sliding plate 32, ensuring a sealed contact between the thermally broken aluminum window frame 1, the hollow sliding plate 32, and the air extraction piston 34. When the glass sash frame 2 is closed, when the glass sash frame 2... Upon contact with the rubber strip 4, as the glass sash frame 2 continues to move, it will push the hollow sliding plate 32 to move backward in the sealing groove of the slide 31. At the same time, the hollow sliding plate 32 slides relative to the air extraction piston 34, drawing out the air inside the frame 33 and reducing the air pressure inside the frame 33. Under the action of atmospheric pressure, the glass sash frame 2 and the rubber strip 4 are tightly fitted, improving the sealing effect between the glass sash frame 2 and the thermally broken aluminum window frame 1, and further improving the heat insulation effect of the thermally broken aluminum window. The sealing mechanism 3 also includes a linkage frame 35, a large gear 36, a small gear 37, and a drive rack plate 38. The linkage frame 35 is located inside the slide 31. The upper longitudinal plate of the linkage frame 35 passes through the clearance sliding hole on the rear side of the hollow sliding plate 32 and is fixedly connected to the air extraction piston 34. The lower longitudinal plate of the frame 35 is a rack plate. Large gears 36 are rotatably connected to the lower end of the slide groove 31 via rotating shafts. The large gears 36 mesh with adjacent linkage frames 35. Small gears 37 are provided on the outer arc surface of the rotating shafts of the large gears 36. Drive rack plates 38 are longitudinally slidably connected to the interior of the slide groove 31. Drive rack plates 38 mesh with small gears 37. When the glass window frame 2 is closed, the glass window frame 2 will contact the front surface of the drive rack plate 38 during its movement, pushing the drive rack plate 38 backward. Through the meshing connection between the drive rack plate 38 and the small gears 37, the small gears 37 drive the coaxial large gears 36 to rotate clockwise. Through the meshing connection between the large gears 36 and the linkage frame 35, the linkage frame 35 is driven to move backward. The diameter of wheel 36 is twice the diameter of pinion 37, ensuring that the moving speed of linkage frame 35 is twice the moving speed of drive rack plate 38. This guarantees that the hollow slide plate 32 slides relative to the suction piston 34 during its movement. Rubber strips 4 are fixedly fitted at both the upper and lower ends of frame 33, making the contact between frame 33 and glass panel frame 2 tighter. Guide plates 7 are provided on both the left and right sides of hollow slide plate 32. Springs 6 are provided between guide plates 7 and the rear inner wall of slide groove 31. Guide posts 5 are provided on the rear inner wall of slide groove 31. The front ends of guide posts 5 pass through the interior of springs 6 and slide longitudinally through guide holes in guide plates 7. Under the guidance and support of guide posts 5, the longitudinal movement of hollow slide plate 32 and the extension and retraction of springs 6 are provided.The hollow sliding plate 32 is easily reset when the window is opened by the elastic force of spring 6. The front surface of the drive rack 38 and the front surface of the frame 33 are located in the same vertical plane, ensuring synchronous movement of the drive rack 38 and the frame 33. Supports 8 are provided on the rear inner wall of the slide groove 31, and the supports 8 are longitudinally slidably connected to the guide holes at the rear end of the drive rack 38, providing guidance and support for the longitudinal movement of the drive rack 38.

[0022] The working principle of the thermally broken aluminum window structure provided by this utility model is as follows: During use, the thermal insulation strip in the middle of the thermally broken aluminum window frame 1 blocks heat conduction between the inner and outer aluminum alloy frame plates, improving the thermal insulation effect of the thermally broken aluminum window. When the glass sash frame 2 is closed, after the glass sash frame 2 contacts the rubber strip 4, as the glass sash frame 2 continues to move, it will overcome the elastic force of the spring 6, pushing the hollow sliding plate 32 backward in the sealed sliding groove of the sliding groove 31. Simultaneously, during the movement, the glass sash frame 2 will contact the front surface of the drive rack plate 38 and push the drive rack plate 38 backward. Through the meshing connection between the drive rack plate 38 and the pinion 37, the pinion 37 drives the coaxial large gear 36 to... The mechanism rotates clockwise, and through the meshing connection between the large gear 36 and the linkage frame 35, it drives the linkage frame 35 to move backward. Because the diameter of the large gear 36 is twice the diameter of the small gear 37, the speed at which the linkage frame 35 moves is twice that of the driving rack plate 38. The linkage frame 35 drives the air extraction piston 34 to slide inside the hollow slide plate 32, extracting the air from inside the frame 33 and reducing the air pressure inside the frame 33. After the glass sash frame 2 is closed, the position of the glass sash frame 2 remains unchanged, maintaining a negative pressure state inside the frame 33. Under the action of atmospheric pressure, the glass sash frame 2 and the rubber strip 4 are tightly fitted, improving the sealing effect between the glass sash frame 2 and the thermally broken aluminum window frame 1, and further improving the heat insulation effect of the thermally broken aluminum window.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
