[0001] The present invention relates to the technical field of aluminum alloy doors and windows, and particularly relates to a combined aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles as frames, mullions, and sash materials, and are abbreviated as aluminum doors and windows. There are five types of aluminum alloy doors and windows: sliding aluminum alloy doors, sliding aluminum alloy windows, casement aluminum alloy doors, casement aluminum alloy windows, and aluminum alloy floor spring doors. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing member substrate and those combined with wood and plastic, abbreviated as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows.

[0003] Currently, when the existing aluminum alloy doors and windows are in use, they are soundproofed by double-layer glass, but the soundproofing effect is not very ideal. In the hot summer, the heat insulation effect is also relatively poor, and it cannot ensure the light brightness while isolating the heat of the sun's rays. Summary of the Invention

[0004] The purpose of the present invention is to provide a combined aluminum alloy door and window to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A combined aluminum alloy door and window, comprising:

[0007] The inner window includes an inner frame body. A transmission cavity is formed in the upper part of the side wall of the inner frame body. Glasses are respectively installed on the inner and outer sides of the inner frame body. An isolation cavity is provided between the two glasses. A storage box is installed at the top of the isolation cavity. A first winding shaft and a second winding shaft are rotatably nested inside the storage box. A soundproof, heat-insulating and transparent film is wound around the first winding shaft, and a soundproof and light-blocking cloth is wound around the second winding shaft;

[0009] Preferably, one end of the soundproof, heat-insulating and transparent film is wound around the first winding shaft, and the other end of the soundproof, heat-insulating and transparent film extends out of the storage box. One end of the soundproof, heat-insulating and transparent film extending out of the storage box is connected to a first counterweight shaft;

[0010] Due to the first counterweight shaft, the part of the soundproof, heat-insulating and transparent film extending out of the storage box is in a taut state, facilitating the lowering of the soundproof, heat-insulating and transparent film.

[0011] Preferably, one end of the sound insulation and light shielding cloth is wound around the second winding shaft, and the other end of the sound insulation and light shielding cloth extends out of the storage box. A second counterweight shaft is connected to the end of the sound insulation and light shielding cloth that extends out of the storage box;

[0012] The second counterweight shaft makes the part of the sound insulation and light shielding cloth extending out of the storage box in a taut state, which is convenient for putting down the sound insulation and light shielding cloth.

[0013] Preferably, the driving mechanism includes a moving frame, a rotating shaft, a first bevel gear, and a second bevel gear;

The double-sided bevel gear is located between the first bevel gear and the second bevel gear, and the double-sided bevel gear is respectively matched with the first bevel gear and the second bevel gear;

[0015] When the double-sided bevel gear moves forward and contacts the first bevel gear, the rotation of the double-sided bevel gear can drive the rotation of the first bevel gear, so that the first winding shaft rotates, thereby realizing the putting down or winding up of the sound insulation and heat insulation transparent film. When the double-sided bevel gear moves backward and contacts the second bevel gear, the rotation of the double-sided bevel gear can drive the rotation of the second bevel gear, so that the second winding shaft rotates, thereby realizing the putting down or winding up of the sound insulation and light shielding cloth.

[0016] Preferably, the front end of the rotating shaft slidably penetrates through the front side wall of the transmission cavity and extends to the outside of the inner frame body. A push-pull rotating block is fixed at the front end of the rotating shaft. The push-pull rotating block is convenient for pushing or pulling the rotating shaft to move, thereby pulling the double-sided bevel gear forward to contact the first bevel gear, or pushing the double-sided bevel gear backward to contact the second bevel gear, and rotating the push-pull rotating block is convenient for driving the surface bevel gear to rotate.

[0020] Under the elastic force of the first spring, the first limiting clamping plate is in contact with the first bevel gear, and the first bevel gear is locked by the first teeth on the first limiting clamping plate, so as to lock the first winding shaft and prevent the first winding shaft from rotating. When the moving frame moves forward, it pushes the first limiting clamping plate away from the first bevel gear, releases the locking of the first bevel gear, and thus releases the locking of the first winding shaft;

[0021] Under the elastic force of the second spring, the second limiting clamping plate is in contact with the second bevel gear, and the second bevel gear is locked by the second teeth on the second limiting clamping plate, so as to lock the second winding shaft and prevent the second winding shaft from rotating.

By providing a storage box between two glasses, the storage box stores a sound insulation and heat insulation transparent film and a sound insulation and light shielding cloth, and the retracting and releasing adjustment is carried out through a driving mechanism. The sound insulation and heat insulation transparent film and the sound insulation and light shielding cloth can be put down at the same time to form a new sound insulation layer, thereby improving the sound insulation effect and making the combined aluminum alloy doors and windows have good sound insulation effect;

[0043] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0044] The present invention provides a combined aluminum alloy door and window as shown in Figures 1 to 9 and includes:

[0045] An outer frame 1 and two inner windows 2 symmetrically and rotatably installed in the outer frame 1;

[0046] The inner window 2 includes an inner frame body 3. A transmission cavity 4 is opened in the upper part of the side wall of the inner frame body 3. Glass 5 is installed on the inner and outer sides of the inner frame body 3 respectively. An isolation cavity 6 is provided between the two glasses 5. A storage box 7 is installed at the top of the isolation cavity 6. A first winding shaft 8 and a second winding shaft 9 are rotatably nested inside the storage box 7. A sound insulation and heat insulation transparent film 10 is wound on the first winding shaft 8, and a sound insulation and light shielding cloth 11 is wound on the second winding shaft 9;

[0047] One ends of the first winding shaft 8 and the second winding shaft 9 close to the transmission cavity 4 extend into the transmission cavity 4. A driving mechanism for driving the first winding shaft 8 and the second winding shaft 9 to rotate forward and backward is provided in the transmission cavity 4.

[0048] As shown in Figures 2 to 3 , one end of the sound insulation and heat insulation transparent film 10 is wound on the first winding shaft 8, the other end of the sound insulation and heat insulation transparent film 10 extends out of the storage box 7, and one end of the sound insulation and heat insulation transparent film 10 extending out of the storage box 7 is connected with a first counterweight shaft 12;

[0049] One end of the sound insulation and light shielding cloth 11 is wound on the second winding shaft 9, the other end of the sound insulation and light shielding cloth 11 extends out of the storage box 7, and one end of the sound insulation and light shielding cloth 11 extending out of the storage box 7 is connected with a second counterweight shaft 13.

[0050] The part of the sound insulation and heat insulation transparent film 10 extending out of the storage box 7 is in a taut state through the first counterweight shaft 12, which facilitates the lowering of the sound insulation and heat insulation transparent film 10. The part of the sound insulation and light shielding cloth 11 extending out of the storage box 7 is in a taut state through the second counterweight shaft 13, which facilitates the lowering of the sound insulation and light shielding cloth 11.

[0051] As Figures 4 to 9 shown, the driving mechanism includes a moving frame 14, a rotating shaft 15, a first bevel gear 16 and a second bevel gear 17;

[0052] The first bevel gear 16 is fixedly installed at one end of the first winding shaft 8 in the transmission cavity 4. The second bevel gear 17 is fixedly installed on the second winding shaft 9. The moving frame 14 is slidably connected to the side wall of the transmission cavity 4 close to the storage box 7. The rotating shaft 15 is rotatably installed in the moving frame 14. A double-sided bevel gear 18 is fixedly sleeved on the shaft body of the rotating shaft 15 in the moving frame 14. The double-sided bevel gear 18 is between the first bevel gear 16 and the second bevel gear 17, and the double-sided bevel gear 18 is respectively matched with the first bevel gear 16 and the second bevel gear 17;

[0053] When the double-sided bevel gear 18 moves forward and contacts the first bevel gear 16, the rotation of the double-sided bevel gear 18 can drive the rotation of the first bevel gear 16, so that the first winding shaft 8 rotates, thereby realizing the lowering or winding of the sound insulation and heat insulation transparent film 10. When the double-sided bevel gear 18 moves backward and contacts the second bevel gear 17, the rotation of the double-sided bevel gear 18 can drive the rotation of the second bevel gear 17, so that the second winding shaft 9 rotates, thereby realizing the lowering or winding of the sound insulation and light shielding cloth 11.

[0054] The front end of the rotating shaft 15 slidably penetrates through the front side wall of the transmission cavity 4 and extends outside the inner frame body 3. A push-pull rotating block 19 is fixed at the front end of the rotating shaft 15. It is convenient to push or pull the rotating shaft 15 to move through the push-pull rotating block 19, thereby pulling the double-sided bevel gear 18 forward to contact the first bevel gear 16, or pushing the double-sided bevel gear 18 backward to contact the second bevel gear 17, and it is convenient to drive the double-sided bevel gear 18 to rotate by rotating the push-pull rotating block 19.

[0055] The first bevel gear 16 is located in front of the second bevel gear 17. A first limit clamping plate 20 abuts against the front side of the first bevel gear 16. The first limit clamping plate 20 is slidably connected to the side wall of the transmission cavity 4 close to the storage box 7. A first spring 21 is connected between the front side of the first limit clamping plate 20 and the front side wall of the transmission cavity 4. The first limit clamping plate 20 is provided with first teeth on the side close to the first bevel gear 16;

[0056] The rear side of the second bevel gear 17 abuts against a second limit clamping plate 22. The second limit clamping plate 22 is slidably connected to a side wall of the transmission cavity 4 close to the storage box 7. A second spring 23 is connected between the rear side of the second limit clamping plate 22 and the rear side wall of the transmission cavity 4. A second set of teeth is provided on the side of the second limit clamping plate 22 close to the second bevel gear 17;

[0057] The front and rear ends of the moving frame 14 respectively abut against the first limit clamping plate 20 and the second limit clamping plate 22;

[0058] Under the elastic force of the first spring 21, the first limit clamping plate 20 abuts against the first bevel gear 16, and the first bevel gear 16 is locked by the first set of teeth on the first limit clamping plate 20, so as to lock the first winding shaft 8 and prevent the first winding shaft 8 from rotating. When the moving frame 14 moves forward, it pushes the first limit clamping plate 20 away from the first bevel gear 16, releases the locking of the first bevel gear 16, and thus releases the locking of the first winding shaft 8;

[0059] Under the elastic force of the second spring 23, the second limit clamping plate 22 abuts against the second bevel gear 17, and the second bevel gear 17 is locked by the second set of teeth on the second limit clamping plate 22, so as to lock the second winding shaft 9 and prevent the second winding shaft 9 from rotating. When the moving frame 14 moves backward, it pushes the second limit clamping plate 22 away from the second bevel gear 17, releases the locking of the second bevel gear 17, and thus releases the locking of the second winding shaft 9.

[0060] As Figure 9 shown, the moving frame 14 includes an upper plate 24 and a lower plate 25. Two support plates 26 are fixed between the upper plate 24 and the lower plate 25. The structure of the moving frame 14 is simple and convenient to manufacture;

[0061] The rotating shaft 15 is rotatably connected to the two support plates 26. The double-sided bevel gear 18 is located between the two support plates 26, so that the rotating shaft 15 is stably installed and rotates stably.

[0062] As Figure 9 shown, the double-sided bevel gear 18 is composed of two bevel gears symmetrically welded together. It is simple to manufacture. When the double-sided bevel gear 18 moves forward to contact the first bevel gear 16, it can mesh with the first bevel gear 16. When the double-sided bevel gear 18 moves backward to contact the second bevel gear 17, it can mesh with the second bevel gear 17.

[0063] As Figures 2 to 3 shown, a first accommodation cavity 27 and a second accommodation cavity 28 are formed in the storage box 7. The first accommodation cavity 27 is located in front of the second accommodation cavity 28. Openings are formed at the bottoms of the first accommodation cavity 27 and the second accommodation cavity 28;

[0064] The first winding shaft 8 is rotatably installed in the first accommodating cavity 27, and the second winding shaft 9 is rotatably installed in the second accommodating cavity 28. The sound-insulating and heat-insulating transparent film 10 and the sound-insulating and light-shielding cloth 11 respectively penetrate through the corresponding openings.

[0065] In the present invention, when light shielding is required, only need to push the push-pull rotary block 19 in the direction of the inner window 2, so that the push-pull rotary block 19 drives the double-sided bevel gear 18 to move backward through the rotating shaft 15 and contact the second bevel gear 17. At the same time, when the rotating shaft 15 moves, it drives the moving frame 14 to move backward, pushing the second limit clamping plate 22 away from the second bevel gear 17, releasing the locking of the second bevel gear 17, thereby releasing the locking of the second winding shaft 9. Then rotate the push-pull rotary block 19 to drive the double-sided bevel gear 18 to rotate. The double-sided bevel gear 18 rotates and meshes with the second bevel gear 17 to drive the second winding shaft 9 to rotate, so as to realize the lowering or winding of the sound-insulating and light-shielding cloth 11. When the sound-insulating and light-shielding cloth 11 is lowered, light shielding can be carried out. After completion, release the push-pull rotary block 19. Under the elastic force of the second spring 23, the second limit clamping plate 22 abuts against the second bevel gear 17, and the second bevel gear 17 is locked by the second teeth on the second limit clamping plate 22, thereby locking the second winding shaft 9 to prevent the second winding shaft 9 from rotating;

[0066] When it is necessary to ensure the illumination brightness while isolating the heat of the sun's sunlight, only need to push the push-pull rotary block 19 in the direction away from the inner window 2, so that the push-pull rotary block 19 drives the double-sided bevel gear 18 to move forward through the rotating shaft 15 and contact the first bevel gear 16. At the same time, when the rotating shaft 15 moves, it drives the moving frame 14 to move forward. The moving frame 14 moves forward to push the first limit clamping plate 20 away from the first bevel gear 16, releasing the locking of the first bevel gear 16, thereby releasing the locking of the first winding shaft 8. Then rotate the push-pull rotary block 19 to drive the double-sided bevel gear 18 to rotate. The double-sided bevel gear 18 rotates and meshes with the first bevel gear 16 to drive the first winding shaft 8 to rotate, so as to realize the lowering or winding of the sound-insulating and heat-insulating transparent film 10. When the sound-insulating and heat-insulating transparent film 10 is lowered, the illumination brightness can be ensured while isolating the heat of the sun's sunlight;

[0067] When only sound insulation is needed, the sound-insulating and heat-insulating transparent film 10 or the sound-insulating and light-shielding cloth 11 can be lowered separately for sound insulation, or the sound-insulating and heat-insulating transparent film 10 and the sound-insulating and light-shielding cloth 11 can be lowered simultaneously to form a new sound-insulating layer, thereby improving the sound-insulating effect and making the combined aluminum alloy doors and windows have good sound-insulating performance.

[0068] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
