Description

Technical Field

[0001] This invention relates to the field of aluminum alloy door and window technology, specifically to an aluminum alloy door and window with adjustable window gaps. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. They are also called aluminum doors and windows for short. Aluminum alloy doors and windows usually include a window frame and a window body. The window body and the window frame are connected by a rotating joint to achieve the purpose of adjusting the window gap.

[0003] Most current window frames and window bodies are connected by hinges, which have a low coefficient of friction and weak stability between the window frame and window body. The window body is easy to close, thus reducing ventilation. At the same time, the window body and window frame are mostly sealed by sealing strips. When the window body is opened and closed, friction occurs between the window body and the sealing strip, which can easily cause the sealing strip to fall off, reducing the service life of the sealing strip. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum alloy door and window with adjustable window gaps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable aluminum alloy door and window includes a window body and a window frame. The window frame has symmetrically distributed cavities inside. A rotating rod passes through the window body and is rotatably connected to the window frame. Both ends of the rotating rod extend into two cavities. Each cavity is equipped with a self-locking component. When the window body is opened outward, the self-locking component restricts the rotation of the rotating rod to fix the window body. The bottom of the window frame has a groove, and a sealing strip is slidably connected inside the groove. The sealing strip is connected to a pop-out component. When the window body is about to close, the pop-out component pops out the sealing strip to achieve a seal between the window body and the window frame.

[0007] Preferably, the self-locking assembly includes a turntable fixed to the outside of the rotating rod. The turntable has circumferentially distributed slots on its side wall. The cavity has a locking block that matches the slots. The side of the locking block away from the turntable is connected to the inner wall of the cavity via a first spring. The inner wall of the cavity has a guide groove. The locking block is fixedly connected to a guide rod that matches the guide groove. The guide rod extends into the guide groove and slides with the inner wall of the guide groove. The guide rod has the function of inserting into the guide groove, and the guide groove has the function of facilitating the sliding of the locking block and the guide rod.

[0008] Preferably, a first traction rope is fixedly connected to the end of the guide rod. The first traction rope passes through the side wall of the window frame. An L-shaped locking rod is fixedly connected to one end of the first traction rope that passes through the side wall of the window frame. A limiting groove adapted to the L-shaped locking rod is provided on the side wall of the window frame. The limiting groove has the function of placing the first traction rope.

[0009] Preferably, a stop rod is slidably connected inside the limiting groove, and a slider is fixedly connected to the stop rod. A groove is provided on the side wall of the limiting groove, and the slider is located inside the groove and slidably connected to it. One side of the slider abuts against the inner wall of the groove. A second spring is provided inside the groove, and the other side of the slider is connected to another inner wall of the groove through the second spring. A channel is connected to the side wall of the groove away from the slider, and the channel extends into the cavity. A take-up roller is fixedly connected to the outside of the rotating rod, and a second traction rope is fixedly connected to the slider. The second traction rope passes through the channel and is fixedly connected to the take-up roller. The second traction rope has the function of driving the slider to move.

[0010] Preferably, the pop-out assembly includes a first air bag fixed inside the cavity, a cam fixedly connected to the outside of the rotating rod to compress the first air bag, a second air bag fixed inside the groove, the second air bag being in contact with the bottom of the sealing strip, an air pipe being provided inside the sealing strip, and the second air bag being connected to the first air bag through the air pipe, the air pipe having the function of conveying gas.

[0011] Preferably, a pressure plate is provided between the cam and the first air bag, and the bottom of the pressure plate is in contact with the first air bag. Multiple slide rods are fixedly connected inside the cavity, and the slide rods pass through the pressure plate and are slidably connected to it. The cam has the function of squeezing the first air bag. Both the first air bag and the second air bag are provided with an expansion layer inside, and the materials of the first air bag and the second air bag are both wear-resistant materials.

[0012] Preferably, the bottom of the sealing strip is fixedly connected with multiple limiting rods, the lower end of the limiting rods extends into the window frame and is slidably connected thereto, and a third spring is provided on the outside of the limiting rod. The two ends of the third spring are fixedly connected to the top of the sealing strip and the bottom of the groove, respectively. The third spring has the function of facilitating the reset of the limiting rod.

[0013] Preferably, the rotating rod is rotatably connected to the window frame via an elastic component, which provides a rotational force to the rotating rod to improve the stability between the window and the window frame.

[0014] Preferably, the elastic component includes a push plate fixed to the outside of the rotating rod, and the cavity has a plurality of circumferentially distributed truncated cones inside. The inclined surface of the truncated cones abuts against the push plate. A fourth spring is fixedly connected to the bottom of the truncated cones. The end of the fourth spring away from the truncated cones is fixedly connected to the inner wall of the cavity. A support rod is fixedly connected to the bottom of the truncated cones. The support rod extends into the window frame and is slidably connected to it. The support rod facilitates sliding with the window frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The window gap size can be adjusted by using the rotating rod to connect with the window frame. The self-locking component restricts the rotation of the rotating rod, thereby restricting the rotation of the window, which effectively improves the stability between the window and the window frame, allowing the window to be opened for a long time and ensuring ventilation.

[0017] 2. By providing a rotational elastic force to the rotating rod through the elastic component, the self-locking component and the elastic component work together to restrict the rotation of the window on the one hand, and to a certain extent, also to restrict the window from continuing to open outward, further improving the stability between the window and the window frame;

[0018] 3. When the window is about to close, the pop-out component ejects the sealing strip from inside the groove. The top of the sealing strip fits tightly against the bottom of the window, sealing the window and frame and preventing rainwater from seeping into the room from the bottom of the window. The sealing strip only moves upward to achieve a seal when the window is about to close, reducing friction between the window and the sealing strip and preventing the sealing strip from falling off due to prolonged opening and closing of the window, thus extending the service life of the sealing strip.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 3 An adjustable aluminum alloy door and window includes a window body 2 and a window frame 1. The window frame 1 has symmetrically distributed cavities 102 inside. A rotating rod 4 passes through the window body 2 and is rotatably connected to the window frame 1. The two ends of the rotating rod 4 extend into the two cavities 102 respectively. Each cavity 102 is equipped with a self-locking component. When the window body 2 is opened outward, the self-locking component is used to restrict the rotation of the rotating rod 4 to fix the window body 2. The bottom of the window frame 1 is provided with a groove 101. A sealing strip 3 is slidably connected inside the groove 101. The sealing strip 3 is connected to a pop-out component. When the window body 2 is about to close, the pop-out component is used to pop out the sealing strip 3 to achieve a seal between the window body 2 and the window frame 1.

[0031] In this embodiment, rotating the window 2 outwards allows for adjustment of the window gap size via the rotating rod 4 and the window frame 1, improving ventilation and enhancing the practicality of the window 2. During the outward rotation of the window 2, the self-locking component inside the cavity 102 restricts the rotation of the rotating rod 4, thereby restricting the rotation of the window 2. This effectively improves the stability between the window 2 and the window frame 1, allowing the window 2 to be opened for extended periods while maintaining ventilation. When the window 2 is about to close, the window 2 ejects the sealing strip 3 from inside the groove 101 via the pop-out component. The top of the sealing strip 3 fits tightly against the bottom of the window 2, providing a seal between the window 2 and the window frame 1. This prevents rainwater from seeping into the room from the bottom of the window 2. Furthermore, the sealing strip 3 only moves upwards to achieve a seal when the window 2 is about to close, reducing friction between the window 2 and the sealing strip 3. This prevents the sealing strip 3 from falling off due to prolonged opening and closing of the window 2, thus extending the service life of the sealing strip 3.

[0032] Please see Figure 3 and Figure 4 The self-locking assembly includes a turntable 6 fixed to the outside of the rotating rod 4. The turntable 6 has circumferentially distributed slots 601 on its side wall. The cavity 102 has a locking block 9 adapted to the slots 601 inside. The side of the locking block 9 away from the turntable 6 is connected to the inner wall of the cavity 102 through a first spring 11. The inner wall of the cavity 102 has a guide groove. The locking block 9 is fixedly connected to a guide rod 10 adapted to the guide groove. The guide rod 10 extends into the guide groove and slides in connection with the inner wall of the guide groove.

[0033] When adjusting the window gap, the window body 2 is rotated outward. The window body 2 drives the turntable 6 to rotate via the rotating rod 4. As the turntable 6 rotates, it presses against the inclined surface of the locking block 9, causing the locking block 9 to move away from the turntable 6. When the window gap adjustment is complete, the locking block 9 automatically enters one of the slots 601 under the action of the first spring 11. The flat surface of the locking block 9 then limits the turntable 6 through the slot 601, thereby restricting the rotation of the rotating rod 4 through the turntable 6. This effectively improves the stability between the window body 2 and the window frame 1, allowing the window body 2 to be opened for a long time and ensuring ventilation. The cross-section of the locking block 9 can be trapezoidal, and the guide groove guides the locking block 9 through the guide rod 10, ensuring the stability of the locking block 9 when it moves.

[0034] Please see Figure 4 and Figure 5 The guide rod 10 is fixedly connected to a first traction rope 12 at its end. The first traction rope 12 passes through the side wall of the window frame 1. One end of the first traction rope 12 that passes through the side wall of the window frame 1 is fixedly connected to an L-shaped locking rod 13. The side wall of the window frame 1 is provided with a limiting groove 14 that is adapted to the L-shaped locking rod 13.

[0035] When it is necessary to close window 2, insert the lower end of L-shaped lever 13 into the limiting groove 14. During the insertion process, L-shaped lever 13 pulls the lever 9 to the outside of the slot 601 through the first traction rope 12 and guide rod 10. The lever 9 is no longer limited, and window 2 can be closed at this time.

[0036] In another embodiment, please refer to Figure 4 and Figure 5 The limiting groove 14 is slidably connected to a stop rod 15, and the stop rod 15 is fixedly connected to a slider 16. The limiting groove 14 has a sliding groove on its side wall. The slider 16 is located inside the sliding groove and is slidably connected to it. One side of the slider 16 is in contact with the inner wall of the sliding groove, and the other side of the slider 16 is connected to the other inner wall of the sliding groove through a second spring 17. A channel is connected to the side wall of the sliding groove away from the slider 16. The channel extends into the cavity 102. The rotating rod 4 is fixedly connected to a take-up roller 7. The slider 16 is fixedly connected to a second traction rope 701. The second traction rope 701 passes through the channel and is fixedly connected to the take-up roller 7.

[0037] In this embodiment, during the closing process of window 2, the rotating rod 4 drives the take-up roller 7 to rotate. As window 2 closes, the second traction rope 701 is in a taut state. When window 2 is about to close, the take-up roller 7 drives the slider 16 to slide inside the slide groove through the second traction rope 701. The slider 16 drives the abutment rod 15 to move. The abutment rod 15 pushes the L-shaped locking rod 13 out from inside the limiting groove 14. Without the limiting groove 14 limiting the L-shaped locking rod 13, the locking block 9 automatically resets under the action of the first spring 11, so that when the user opens window 2 again, the locking block 9 can limit the turntable 6 again. The second spring 17 plays a reset role for the abutment rod 15 through the slider 16.

[0038] Please see Figure 6 and Figure 7 The pop-out component includes a first air bag 26 fixed inside the cavity 102, a cam 8 for squeezing the first air bag 26 fixedly connected to the outside of the rotating rod 4, a second air bag 22 fixed inside the groove 101, the second air bag 22 abutting against the bottom of the sealing strip 3, and the second air bag 22 communicating with the first air bag 26 through the air pipe 21.

[0039] When the window 2 is about to close, the rotating rod 4 compresses the first air bag 26 through the cam 8. The gas inside the first air bag 26 enters the second air bag 22 through the air pipe 21. The second air bag 22 expands and compresses the sealing strip 3, so that the top of the sealing strip 3 fits tightly against the bottom of the window 2, improving the sealing performance. Moreover, the sealing strip 3 will only move upward to achieve a seal when the window 2 is about to close, reducing the friction between the window 2 and the sealing strip 3. This can prevent the sealing strip 3 from falling off due to long-term opening and closing of the window 2, and improve the service life of the sealing strip 3.

[0040] Please see Figure 6 A pressure plate 25 is provided between the cam 8 and the first air bag 26. The bottom of the pressure plate 25 is in contact with the first air bag 26. A plurality of slide rods 27 are fixedly connected inside the cavity 102. The slide rods 27 pass through the pressure plate 25 and are slidably connected to it.

[0041] When window 2 is about to close, cam 8 squeezes the first air bag 26 through pressure plate 25. The setting of pressure plate 25 makes the first air bag 26 bear force evenly, which improves the service life of the first air bag 26. The slide bar 27 plays a limiting role on pressure plate 25, which improves the stability of pressure plate 25 when it moves.

[0042] Please see Figure 7 The bottom of the sealing strip 3 is fixedly connected to a plurality of limiting rods 24. The lower end of the limiting rods 24 extends into the window frame 1 and is slidably connected thereto. A third spring 23 is provided on the outside of the limiting rods 24. The two ends of the third spring 23 are fixedly connected to the bottom of the sealing strip 3 and the bottom of the groove 101, respectively.

[0043] The third spring 23 acts as a reset mechanism for the sealing strip 3. When the window 2 is opened, the cam 8 no longer squeezes the first air bag 26. Under the action of the third spring 23, the sealing strip 3 automatically enters the groove 101. As the sealing strip 3 moves downward, it squeezes the second air bag 22. The gas inside the second air bag 22 flows back to the first air bag 26 through the air pipe 21. The window frame 1 uses the limiting rod 24 to reset the sealing strip 3, which improves the stability of the sealing strip 3 when it moves.

[0044] In another embodiment, please refer to Figure 2 and Figure 8 The rotating rod 4 is rotatably connected to the window frame 1 through an elastic component. The elastic component is used to provide a rotational elastic force to the rotating rod 4 to improve the stability between the window 2 and the window frame 1.

[0045] In this embodiment, the self-locking component restricts the rotation of the rotating rod 4, and the elastic component provides a rotational elastic force to the rotating rod 4. Through the cooperation of the self-locking component and the elastic component, the rotating rod 4 is fixed. On the one hand, it can restrict the rotation of the window 2, and on the other hand, it can also restrict the window 2 from continuing to open outward to a certain extent, further improving the stability between the window 2 and the window frame 1. The elastic component can be a torsion spring. Both ends of the rotating rod 4 are rotatably connected to the inner wall of the cavity 102 through the torsion spring. The torsion spring applies a rotational elastic force to the rotating rod 4, and in conjunction with the use of the self-locking component, it can effectively improve the stability between the window 2 and the window frame 1. When the self-locking component no longer restricts the window 2 from closing, the rotating rod 4 automatically rotates under the action of the torsion spring, and the window 2 can automatically close.

[0046] In another embodiment, please refer to Figure 8 The elastic component includes a push plate 5 fixed to the outside of the rotating rod 4. The cavity 102 has a plurality of truncated cones 18 arranged in a circular pattern. The inclined surface of the truncated cones 18 abuts against the push plate 5. A fourth spring 19 is fixedly connected to the bottom of the truncated cones 18. The end of the fourth spring 19 away from the truncated cones 18 is fixedly connected to the inner wall of the cavity 102. A support rod 20 is fixedly connected to the bottom of the truncated cones 18. The support rod 20 extends into the window frame 1 and is slidably connected to it.

[0047] When window 2 is opened to a certain position, the torsion spring is compressed to its maximum extent. At this time, window 2 may not be able to open normally. In this embodiment, the torsion spring is replaced by the push plate 5, the frustum 18, and the fourth spring 19. The rotating rod 4 rotates while driving the push plate 5 to rotate. The push plate 5 presses against the inclined surface of the frustum 18, and the frustum 18 presses against the fourth spring 19. The fourth spring 19 applies a rotational elastic force to the rotating rod 4 through the frustum 18 and the push plate 5, thereby improving the stability between window 2 and window frame 1. When the opening angle of window 2 is large, the push plate 5 slides over the top of one of the frustums 18. At this time, the inclined surface of the next frustum 18 will continue to apply a rotational elastic force to the rotating rod 4 through the push plate 5, which can effectively avoid the phenomenon that the torsion spring is compressed to its maximum extent, causing window 2 to be unable to open normally.

[0048] Working Principle: This aluminum alloy door and window utilizes the rotating connection between the rotating rod 4 and the window frame 1 to adjust the window gap size, improving ventilation and enhancing the practicality of the window 2. During the outward rotation of the window 2, the rotating rod 4 drives the turntable 6 to rotate. Simultaneously, the turntable 6 presses against the inclined surface of the locking block 9, causing the locking block 9 to move away from the turntable 6. When the window gap adjustment is complete, the locking block 9 automatically enters one of the slots 601 under the action of the first spring 11. The plane of the locking block 9 then limits the rotation of the turntable 6 through the slot 601, thereby restricting the rotation of the rotating rod 4. This effectively improves the stability between the window 2 and the window frame 1, allowing the window 2 to be opened for extended periods and ensuring ventilation. Simultaneously, the rotation of the rotating rod 4 also drives the push plate 5 to rotate. The push plate 5 presses against the inclined surface of the frustum 18, which in turn presses against the fourth... Spring 19, the fourth spring 19, applies a rotational force to the rotating rod 4 through the frustum 18 and the push plate 5. On the one hand, it can limit the rotation of the window 2, and on the other hand, it can also limit the window 2 from continuing to open outward to a certain extent, which further improves the stability between the window 2 and the window frame 1. When the window 2 is about to close, the rotating rod 4 squeezes the first air bag 26 through the cam 8. The gas inside the first air bag 26 enters the second air bag 22 through the air pipe 21. The second air bag 22 expands and squeezes the sealing strip 3, so that the top of the sealing strip 3 fits tightly with the bottom of the window 2, which improves the sealing performance. The sealing strip 3 will only move upward to achieve a seal when the window 2 is about to close, which reduces the friction between the window 2 and the sealing strip 3, and can avoid the phenomenon of the sealing strip 3 falling off due to long-term opening and closing of the window 2, thus improving the service life of the sealing strip 3.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
