Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a high-sealing, energy-saving aluminum alloy door and window. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made using extruded aluminum alloy profiles for the frame, mullions, and sashes. They are also known simply as aluminum doors and windows. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing structural members to support and transmit their own weight and loads, as well as those made of wood or plastic composites, referred to as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows. Currently, most aluminum alloy doors and windows are sliding structures, providing ventilation and rain protection.
[0003] Currently, existing aluminum alloy doors and windows suffer from poor sealing due to the gap between the two sliding windows, leading to problems such as water seepage and drafts. Furthermore, the rapid exchange rate between indoor and outdoor air causes energy loss when heating or cooling equipment is turned on, making it difficult to achieve energy-saving effects. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a high-sealing, energy-saving aluminum alloy door and window.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-sealing energy-saving aluminum alloy door and window, including a rectangular window frame and two sliding windows. The two sliding windows are horizontally slidably arranged in the rectangular window frame. Each of the two sliding windows has an installation groove on an adjacent side. An elastic rubber sheet is provided at the opening of the installation groove. A pushing rod is slidably arranged in the installation groove. A plurality of grooves are provided on one side of the pushing rod, which are spaced apart along its length. A magnet is provided in the groove.
[0006] By employing the above technical solution, which includes mounting grooves, pushing rods, and magnets, when the two sliding windows slide to the closed position within the rectangular window frame, the elastic rubber sheets on both sides align. At this time, the magnets on the two pushing rods attract each other, generating a force that moves the pushing rods closer together. Under the continuous pushing pressure of the pushing rods, the elastic rubber sheets on both sides deform and fit tightly together, completely filling the gap that originally existed between the two elastic rubber sheets, thus achieving high sealing performance of the doors and windows. This effectively prevents water leakage and air leakage problems. When heating or cooling equipment is turned on indoors, the gap between the two sliding windows will not cause indoor and outdoor air exchange, thus achieving energy-saving effects.
[0007] Furthermore, the sliding window is provided with an extension plate on one side of the groove of the mounting slot. One side of the elastic rubber sheet is connected to the side of the extension plate away from the mounting slot, and the other side is connected to the window body of the sliding window on the side of the mounting slot away from the extension plate.
[0008] By adopting the above technical solution and setting an extension plate, the elastic rubber sheet is tilted relative to the sliding window. When the sliding window switches from the closed state to the open state, the tilted elastic rubber sheet can be directly offset during the separation process, avoiding the wear caused by friction when the two elastic rubber sheets move relative to each other in the parallel state of the sliding window. This not only ensures the durability of the sealing structure, but also further consolidates the stable performance of high sealing performance.
[0009] Furthermore, the groove is provided with three fixed tubes arranged at intervals along the length of the push rod, and a slide rod connected to the push rod is slidably disposed in the fixed tube.
[0010] By adopting the above technical solution, a fixed tube and a sliding rod are set up, and the pushing rod and the sliding rod move synchronously. The sliding rod can slide smoothly in the fixed tube. This cooperation provides stable support for the sliding of the pushing rod and ensures the stability of the sliding of the pushing rod.
[0011] Furthermore, the fixing tube is fitted with a tension spring, one end of which is connected to the push rod and the other end is connected to the bottom of the mounting groove.
[0012] By adopting the above technical solution, a tension spring is set up. When the push rod moves and pushes the elastic rubber sheet, the tension spring is stretched. When the sliding window switches from the closed state to the open state, the tension spring releases its elasticity and pulls the push rod back to its original position.
[0013] Furthermore, sealing rubber sheets are provided at both ends of the mounting groove, and the sides of the sealing rubber sheets are respectively connected to the groove wall, the extension plate, and the elastic rubber sheet of the mounting groove.
[0014] By adopting the above technical solution and setting a closed rubber sheet, external dust is prevented from entering the groove wall, extension plate and space between elastic rubber sheets. This effectively prevents dust from adhering to the surface of the slide rod or accumulating around the tension spring, ensuring that the slide rod always slides smoothly in the fixed tube and that the tension spring can also extend and retract stably.
[0015] Furthermore, the sliding window is also provided with an installation strip, and the installation strip is provided with a felt sealing strip.
[0016] By adopting the above technical solution and setting up installation strips and felt sealing strips, when the two sliding windows are closed, the felt sealing strips will fit tightly between the two windows. With their soft and elastic properties, they fill the space between the two sliding windows, forming another layer of sealing defense between the two sliding windows, further enhancing the overall sealing performance and improving the sealing effect more comprehensively.
[0017] Furthermore, the sliding window is provided with a fixing strip, and a T-shaped groove is formed on the fixing strip along its length direction. The mounting strip is slidably connected to the T-shaped groove.
[0018] By adopting the above technical solution, and setting a fixing strip and a T-slot, when the felt sealing strip ages or wears down due to long-term use and affects the sealing effect, after the sliding window is removed from the rectangular window frame, the installation strip can be slid out along the T-slot to replace the felt sealing strip. Then, the new installation strip and the new felt sealing strip can be slid into the T-slot to reset, ensuring the continuous stability of the sealing performance.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, an installation groove, a pushing rod, and magnets are provided. When the two sliding windows slide to the closed position within the rectangular window frame, the elastic rubber sheets on both sides align. At this time, the magnets on the two pushing rods attract each other due to magnetic attraction, causing the pushing rods to move closer to each other. Under the continuous pushing pressure of the pushing rods, the elastic rubber sheets on both sides deform and fit tightly together, completely filling the gap that originally existed between the two elastic rubber sheets, thus achieving high sealing performance of the doors and windows. This effectively avoids water leakage and air leakage problems. When heating or cooling equipment is turned on indoors, the gap between the two sliding windows will not cause indoor and outdoor gas exchange, thus achieving energy-saving effects.
[0021] 2. In this application, an extension plate is provided so that the elastic rubber sheet is tilted relative to the sliding window. When the sliding window is switched from the closed state to the open state, the tilted elastic rubber sheet can be directly offset during the separation process, avoiding the wear caused by friction when the two elastic rubber sheets move relative to each other in the parallel state of the sliding window. This not only ensures the durability of the sealing structure, but also further consolidates the stable performance of high sealing performance.
[0022] 3. In this application, a closed rubber sheet is provided to prevent external dust from entering the groove wall, extension plate and space between elastic rubber sheet. This effectively prevents dust from adhering to the surface of the slide rod or accumulating around the tension spring, ensuring that the slide rod always slides smoothly in the fixed tube and that the tension spring can also extend and retract stably.

Detailed Implementation
[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-6 As shown in the illustration, this application discloses a high-sealing, energy-saving aluminum alloy door and window, including a rectangular window frame 10 and two sliding windows 20. Both sliding windows 20 are horizontally slidably disposed within the rectangular window frame 10. Each sliding window 20 has an installation groove 21 on its adjacent side, with an elastic rubber sheet 22 at the groove opening. A pushing rod 30 is slidably disposed within the installation groove 21. Several grooves are spaced along the length of the pushing rod 30, and magnets 31 are disposed within these grooves. When the two sliding windows 20 slide to the closed state within the rectangular window frame 10, the elastic rubber sheets 22 on both sides align. At this time, the magnets 31 on the two pushing rods 30 generate a force due to magnetic attraction, causing the pushing rods 30 to move closer to each other. Under the continuous pushing pressure of the pushing rods 30, the elastic rubber sheets 22 on both sides deform and fit tightly together, completely filling the gap between the two elastic rubber sheets 22, thus achieving high sealing performance of the door and window. This effectively avoids water seepage and ventilation problems. When heating or cooling equipment is turned on indoors, the gap between the two sliding windows 20 will not cause indoor and outdoor air exchange, thus achieving energy-saving effect.
[0032] Specifically, to avoid wear and tear caused by friction between the two elastic rubber sheets 22 when they move relative to each other in a parallel state with the sliding window 20, an extension plate 23 is provided on one side of the sliding window 20 located in the groove of the mounting groove 21. One side of the elastic rubber sheet 22 is connected to the side of the extension plate 23 away from the mounting groove 21, and the other side is connected to the window body of the sliding window 20 on the side of the mounting groove 21 away from the extension plate 23. This makes the elastic rubber sheet 22 tilted relative to the sliding window 20. When the sliding window 20 switches from the closed state to the open state, the tilted elastic rubber sheet 22 can be directly offset during the separation process, which not only ensures the durability of the sealing structure, but also further consolidates the stable performance of the high sealing performance.
[0033] During installation, three fixed tubes 40 are spaced apart along the length of the push rod 30 within the groove. A sliding rod 41, connected to the push rod 30, is slidably mounted within each fixed tube 40, perpendicular to the push rod 30. The push rod 30 and sliding rod 41 move synchronously, allowing the sliding rod 41 to slide smoothly within the fixed tubes 40. This arrangement provides stable support for the sliding of the push rod 30, ensuring its stability. To ensure the push rod 30 returns to its original position when the sliding window 20 switches from the closed to the open state, a tension spring 42 is fitted over the fixed tube 40. One end of the tension spring 42 is connected to the push rod 30, and the other end is connected to the bottom of the mounting groove 21. When the push rod 30 moves and pushes against the elastic rubber sheet 22, the tension spring 42 is stretched. When the sliding window 20 switches from the closed to the open state, the tension spring 42 releases its elasticity, pulling the push rod 30 back to its original position.
[0034] In the specific configuration, sealing rubber sheets 24 are also provided at both ends of the mounting groove 21. The sides of the sealing rubber sheets 24 are connected to the groove wall of the mounting groove 21, the extension plate 23, and the elastic rubber sheet 22, respectively. The sealing rubber sheets 24 prevent external dust from entering the space between the groove wall, the extension plate 23, and the elastic rubber sheet 22, effectively preventing dust from adhering to the surface of the slide rod 41 or accumulating around the tension spring 42, ensuring that the slide rod 41 always slides smoothly in the fixed tube 40, and that the tension spring 42 can also extend and retract stably.
[0035] The sliding window 20 is also equipped with an installation strip 50, on which a felt sealing strip 51 is installed. When both sliding windows 20 are closed, the felt sealing strip 51 fits tightly between the two windows, filling the space between them with its soft and elastic properties, forming another layer of sealing between the two sliding windows 20, further enhancing the overall sealing performance and improving the sealing effect. The sliding window 20 is also equipped with a fixing strip 52, on which a T-shaped groove 53 is formed along its length, and the installation strip 50 is slidably connected to the T-shaped groove 53. When the felt sealing strip 51 ages or wears down due to long-term use, affecting the sealing effect, after the sliding window 20 is removed from the rectangular window frame 10, simply slide the installation strip 50 along the T-groove 53 to replace the felt sealing strip 51. Then, slide the new installation strip 50 along with the new felt sealing strip 51 into the T-groove 53 to reset it, ensuring the continuous stability of the sealing performance.
[0036] The operating principle of a high-sealing energy-saving aluminum alloy door and window in this embodiment is as follows: When the two sliding windows 20 slide to the closed state within the rectangular window frame 10, the elastic rubber sheets 22 on both sides align. At this time, the magnets 31 on the two push rods 30 generate a force due to magnetic attraction, causing the push rods 30 to move closer to each other. Under the continuous pushing of the push rods 30, the elastic rubber sheets 22 on both sides deform and fit tightly together, completely filling the gap that originally existed between the two elastic rubber sheets 22. The felt sealing strip 51 will fit tightly between the two windows, further enhancing the overall sealing performance.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
