Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy casement doors and windows, and in particular to an energy-saving heat-insulating aluminum alloy casement door and window. Background Art

[0002] Aluminum alloy casement doors and windows are a common type of window and door, widely used in residences, office buildings, and commercial structures. They are favored for their excellent thermal insulation, sound insulation, and corrosion resistance, making them particularly suitable for buildings with high energy-saving and environmental protection requirements. With the increasing demand for energy conservation and environmental protection in the construction industry, building energy conservation has become a key consideration in design and construction. Aluminum alloy casement doors and windows, through their excellent thermal insulation properties, effectively reduce energy loss within buildings, significantly improving their energy efficiency.

[0003] When it comes to building energy conservation, aluminum alloy doors and windows, particularly through their multi-layer insulation and sealing technology, can effectively reduce heat exchange in buildings, lowering winter heating loads and summer air conditioning requirements, thereby achieving energy savings and consumption reductions. Furthermore, aluminum alloy casement doors and windows, through their excellent airtightness and watertightness, reduce energy loss in buildings and maintain a more stable indoor temperature, which is particularly important in the design of energy-efficient buildings.

[0004] The document with the prior art publication number CN221779300U provides a casement aluminum alloy door and window. By setting an adjustment structure, when the window needs to be opened or closed, it is only necessary to start the electric telescopic rod. The piston rod of the electric telescopic rod is extended to drive the window to rotate and open, and the piston rod of the electric telescopic rod is retracted to drive the window to rotate and close. People do not need to manually pull the handle to close the window, thereby avoiding the situation where manual closing of the window is difficult due to the large outward expansion angle of the casement aluminum alloy door and window, the window handle is far away from the room, and the window is exposed to the wind in a large area.

[0005] When opened, existing windows lack effective wind-guiding features, blocking crosswinds from outside, preventing the outside air from flowing smoothly into the room. This design not only reduces the window's ventilation efficiency, but can also cause excessive wind impact on the window structure, resulting in damage or instability.

[0006] In summary, the prior art lacks a technology for guiding air into the room through a window. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] like Figures 1-8The energy-saving heat-insulating aluminum alloy casement door and window shown in the figure includes an aluminum alloy window frame 1, a rotating frame 2 is rotatably connected to the inside of the aluminum alloy window frame 1, an adjustable air guide frame 3 is rotatably connected to the inside of the rotating frame 2, a wiping strip 4 is slidingly fitted on the adjustable air guide frame 3, an adjustment mechanism 5 is rotatably connected to the inner wall of the upper end of the rotating frame 2, an opening and closing mechanism 6 is rotatably connected to the inner wall of the bottom end of the aluminum alloy window frame 1, a transmission shaft 7 is rotatably connected to the inner wall of one side of the aluminum alloy window frame 1, and a gauze curtain 8 is placed on the inner wall of the top end of the aluminum alloy window frame 1.

[0022] like Figure 3 As shown, an opening and closing wheel 201 is fixedly connected to the bottom end of the rotating frame 2.

[0023] like Figure 4 As shown, the inner wall of the adjustable air guide frame 3 is a symmetrical structure and is fixedly connected to a double-layer glass 301, and a vacuum cavity is provided between the double-layer glass 301. The upper and lower ends of the adjustable air guide frame 3 are fixedly connected to a rotating shaft 302, and the rotating shaft 302 is rotatably connected to the rotating frame 2. The outer wall of the rotating shaft 302 at the top is fixedly connected to a worm gear 303, and two sliding grooves 304 are provided on the side of the adjustable air guide frame 3 close to the wiping strip 4.

[0024] By setting up an adjustable air guide frame 3, when the rotating frame 2 is rotated and opened, the adjustable air guide frame 3 can be driven to rotate through the adjustment mechanism 5, so that the adjustable air guide frame 3 is in a tilted state. At this time, the outdoor lateral wind can be effectively guided to flow in through the double-layer glass 301 on the adjustable air guide frame 3. Through the tilted adjustable air guide frame 3, the wind force will be guided and dispersed, reducing the pressure directly impacting the window, thereby reducing the risk of damage or deformation of the window. At the same time, the vacuum cavity inside the double-layer glass 301 reduces heat radiation and convection, thereby achieving a heat insulation effect.

[0025] like Figure 5 As shown, a rubber strip is fixedly connected to the side of the wiping strip 4 facing the double-layer glass 301, and sliders 401 are fixedly connected at both ends of the wiping strip 4. The sliders 401 are slidingly matched with the inner wall of the slide groove 304. A push-pull rod group 402 is rotatably connected to the inner wall of the top end of the wiping strip 4. The top end of the push-pull rod group 402 is rotatably connected to the adjustable air guide frame 3, and a gear 404 is fixedly connected to the outer wall of the top end of the push-pull rod group 402.

[0026] A transmission rack 405 is provided on one side of the gear 404 for meshing transmission. The transmission rack 405 is slidably fitted across the inner wall of the adjustable air guide frame 3. A spring 406 is fixedly connected to the inner end of the transmission rack 405. The other end of the spring 406 is fixedly connected to the inner wall of the adjustable air guide frame 3. A triangular block 403 is fixedly connected to the outer end of the transmission rack 405. The outer wall of the triangular block 403 is in sliding contact with the inner wall of the rotating frame 2. When the adjustable air guide frame 3 rotates, the triangular block 403 no longer contacts the inner wall of the rotating frame 2. The spring 406 drives the connected transmission rack 405 to move, allowing the transmission rack 405 to rotate the push-pull rod assembly 402 connected to the gear 404, which in turn drives the connected wiping strip 4 downward.

[0027] like Figure 6 As shown, the adjustment mechanism 5 includes a worm 501, which is rotatably connected to the inner wall of the rotating frame 2, and the worm 501 is meshingly transmitted with the worm wheel 303. One end of the worm 501 is fixedly connected to a driven wheel 502, and one side of the driven wheel 502 is meshingly transmitted with a transmission wheel 503. The transmission wheel 503 is rotatably connected to the inner wall of the rotating frame 2 through a pin shaft, and the other end of the pin shaft extends through the inner wall of the rotating frame 2 to the outside and is fixedly connected to a driving wheel 504. One side of the driving wheel 504 is meshingly transmitted with a fixed gear plate 505, and the fixed gear plate 505 is fixedly connected to the aluminum alloy window frame 1. As the rotating frame 2 rotates, the fixed gear disc 505 causes the driving wheel 504 engaged therewith to rotate. At this time, the driving wheel 504 drives the connected transmission wheel 503 to rotate, so that the transmission wheel 503 can drive the worm 501 connected to the driven wheel 502 to rotate, so that the worm 501 can drive the adjustable air guide frame 3 connected to the worm wheel 303 to rotate.

[0028] like Figure 7As shown, the opening and closing mechanism 6 includes a universal joint 601, which is rotatably connected to the inner wall of the bottom end of the aluminum alloy window frame 1. A sleeve rod 602 is fixedly connected to one end of the universal joint 601, and a handwheel 603 is slidably provided on the outer wall of the sleeve rod 602. A tension spring 604 is fixedly connected to the handwheel 603, and the other end of the tension spring 604 is fixedly connected to the sleeve rod 602. A threaded rod 605 is fixedly connected to the other end of the universal joint 601, and an adjustment rack 606 is threadedly connected to the outer wall of the threaded rod 605. The adjustment rack 606 is meshed with the opening and closing wheel 201. The tension spring 604 can drive the handwheel 603 to return to the inside of the aluminum alloy window frame 1, avoiding the inconvenience caused by the handwheel 603 being located outside. Pull the handwheel 603 out of the aluminum alloy window frame 1 and rotate it, so that the handwheel 603 can drive the threaded rod 605 connected to the sleeve rod 602 to rotate, so that the threaded rod 605 can drive the adjustment rack 606 to move, so that the adjustment rack 606 can drive the opening and closing wheel 201 to rotate, thereby driving the rotating frame 2 connected to the opening and closing wheel 201 to rotate and open.

[0029] like Figure 7 As shown, a synchronous gear 701 is fixedly connected to the bottom end of the transmission shaft 7, and the synchronous gear 701 is meshed with the opening and closing wheel 201 for transmission. A spiral groove 702 is opened on the outer wall of the transmission shaft 7.

[0030] like Figure 3 、 Figure 8 As shown, one end of the gauze curtain 8 is wound and connected to a gauze curtain shaft 801, which is rotatably connected to the inner wall of the top of the aluminum alloy window frame 1. One end of the gauze curtain shaft 801 is fixedly connected to a coil spring 802, and the other end of the coil spring 802 is fixedly connected to the inner wall of the top of the aluminum alloy window frame 1. The other end of the gauze curtain 8 is fixedly connected to a pull-out frame 803, and the two ends of the pull-out frame 803 are slidably matched with the inner wall of the aluminum alloy window frame 1. The inner walls of both sides of the aluminum alloy window frame 1 are symmetrically fixedly connected with sponge strips 101. One end of the pull-out frame 803 is fixedly connected to a raised ring 804, and the inner wall and the raised part of the raised ring 804 are slidably matched with the outer wall of the drive shaft 7 and the inner wall of the spiral groove 702. The sponge strip 101 can block the gap between the gauze curtain 8 and the aluminum alloy window frame 1, improving the insect-proof effect. The coil spring 802 enables the gauze curtain shaft 801 to drive the gauze curtain 8 to automatically rewind and reset. When the rotating frame 2 rotates, the connected opening and closing wheel 201 will drive the meshing synchronous gear 701 to rotate. At this time, the synchronous gear 701 will drive the connected transmission shaft 7 to rotate. At this time, the transmission shaft 7 will drive the pulling frame 803 connected to the raised ring 804 to move downward through the opened spiral groove 702, so that the gauze curtain 8 can be pulled downward.

[0031] Working principle: When it is necessary to open the window, first grasp and pull the hand wheel 603 outwards, pull the hand wheel 603 out of the aluminum alloy window frame 1 and rotate it, so that the hand wheel 603 can drive the threaded rod 605 connected to the sleeve rod 602 to rotate, so that the threaded rod 605 can drive the adjustment rack 606 to move, so that the adjustment rack 606 can drive the opening and closing wheel 201 to rotate, thereby driving the rotating frame 2 connected to the opening and closing wheel 201 to rotate and open; As the rotating frame 2 rotates, the fixed gear plate 505 causes the driving wheel 504 meshing with it to rotate. At this time, the driving wheel 504 drives the connected transmission wheel 503 to rotate, so that the transmission wheel 503 can drive the worm 501 connected to the driven wheel 502 to rotate, so that the worm 501 can drive the adjustable air guide frame 3 connected to the worm wheel 303 to rotate; When the adjustable air guide frame 3 rotates, the triangular block 403 is no longer in contact with the inner wall of the rotating frame 2. The spring 406 drives the connected transmission rack 405 to move, so that the transmission rack 405 can drive the push-pull rod group 402 connected to the gear 404 to rotate, so that the push-pull rod group 402 can drive the connected wiping strip 4 to move downward, wiping and cleaning the outer side of the double-layer glass 301; At the same time, when the rotating frame 2 rotates, the connected opening and closing wheel 201 will drive the meshing synchronous gear 701 to rotate. At this time, the synchronous gear 701 will drive the connected transmission shaft 7 to rotate. At this time, the transmission shaft 7 will drive the pulling frame 803 connected to the raised ring 804 to move downward through the opened spiral groove 702, so that the gauze curtain 8 can be pulled downward for insect prevention.
