Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy door and window technology, specifically to a heat-insulating aluminum alloy door and window. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made with extruded aluminum alloy profiles as frames, mullions, and sashes. They are also known simply as aluminum doors and windows. Aluminum alloy doors and windows include those using aluminum alloy as the load-bearing structure (the structure that bears and transmits its own weight and load) and those made of wood or plastic composites, referred to as aluminum-wood composite doors and windows or aluminum-plastic composite 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.
[0003] Existing aluminum alloy doors and windows have poor thermal insulation performance, resulting in rapid heat loss when there is a large temperature difference between indoors and outdoors. Furthermore, the aluminum alloy doors and windows currently in use have struts between the sash and the frame to control the opening and closing range of the sash. However, during use, the struts are prone to slippage due to prolonged contact with dust, which affects the smoothness of the aluminum alloy doors and windows. At the same time, the struts make it difficult to clean the inside of the window groove. Utility Model Content
[0004] The purpose of this utility model is to provide a heat-insulating aluminum alloy door and window to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating aluminum alloy door and window, comprising a window frame, a window sash on the window frame, the window sash being rotatably connected to the window frame via a mounting rod, glass embedded in the window sash, a laminated layer within the glass, two sets of symmetrically distributed ratchet wheels sleeved on the mounting rod, two sets of symmetrically distributed pawls within the window frame, both sets of pawls being rotatably connected to the window frame via rotating rods, each set of rotating rods being sleeved with a first gear, two sets of symmetrically distributed first racks within the window frame, the two sets of first racks being fixedly connected via a connecting frame, a fixing block being fixedly mounted on the connecting frame, a fixing rod within the window frame, two sets of symmetrically distributed fixing brackets sleeved on the fixing rod, each set of fixing brackets corresponding to a fixing block, an installation frame fixedly mounted on the window frame, a retractable rod rotatably mounted within the installation frame, and a heat-insulating film sleeved on the retractable rod.

The two ends of the first torsion spring are respectively fixedly connected to the pawl and the window frame.
[0007] As a further preferred embodiment of this technical solution, both sets of the first racks are respectively configured to correspond to the first gear, and the two sets of the first racks are respectively meshed with the corresponding first gear.
[0008] As a further preferred embodiment of this technical solution, both sets of fixing frames are movably engaged with the fixing block, and a second torsion spring is sleeved on the fixing rod. The two ends of the second torsion spring are respectively fixedly connected to the two sets of fixing frames and the fixing rod.
[0009] As a further preferred embodiment of this technical solution, a locking rod is slidably installed inside the mounting frame. The left side of the locking rod is movably engaged with the mounting frame. The locking rod is fixedly connected to the end of the insulation film away from the winding rod. Two sets of symmetrically distributed disc springs are sleeved on the winding rod. The inner and outer ends of the disc springs are fixedly connected to the winding rod and the mounting frame, respectively.
[0010] As a further preferred embodiment of this technical solution, the mounting frame is provided with two sets of symmetrically distributed card holders. The two sets of card holders are respectively movably engaged with the card rod. Each set of card holders is fixedly sleeved with a stop block. The two sets of card holders are slidably connected to the mounting frame through the stop block. Each set of card holders is sleeved with a spring.

[0012] This utility model provides a heat-insulating aluminum alloy door and window, which has the following beneficial effects:
[0013] (1) This utility model achieves a certain degree of heat insulation by setting a vacuum-laminated glass, and limits the rotation angle of the ratchet by setting two sets of pawls, thereby limiting the opening and closing angle of the window sash, avoiding the problem that the window sash cannot be firmly fixed when it is not needed. Moreover, the ratchet and pawl are set inside the window sash and the window frame, so they will not rust or lose their function due to contact with dust in the air for a long time. Furthermore, the ratchet and pawl are located inside, which not only achieves control over the opening and closing range of the window sash, but also does not affect the cleaning of the aluminum alloy door and window groove.
[0014] (2) This utility model further enhances the thermal insulation performance of the aluminum alloy doors and windows in some usage environments by setting the installation frame and the retractable thermal insulation film in the installation frame, based on the glass containing the laminate. When used in a cold environment, the thermal insulation film is pulled out in the installation frame by the clamp rod, and the handle is turned to drive the second gear to rotate synchronously. With the cooperation of two sets of second racks, the two sets of clamps are slid synchronously, which makes it easy for the clamp rod to engage into the installation frame. After the handle is released, the two sets of clamps automatically engage with the clamp rod under the action of the spring and the third torsion spring, so that the thermal insulation film covers the doors and windows, thus enhancing the thermal insulation function of the aluminum alloy doors and windows.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a heat-insulating aluminum alloy door and window includes a window frame 1, a window sash 2 on the window frame 1, the window sash 2 being rotatably connected to the window frame 1 via a mounting rod 5, a glass 3 embedded in the window sash 2, a laminated layer 4 within the glass 3, two sets of symmetrically distributed ratchet wheels 6 sleeved on the mounting rod 5, two sets of symmetrically distributed pawls 8 inside the window frame 1, both sets of pawls 8 being rotatably connected to the window frame 1 via rotating rods 7, both sets of rotating rods 7 being sleeved with first gears 10, two sets of symmetrically distributed first racks 11 inside the window frame 1, the two sets of first racks 11 being fixedly connected by a connecting frame 12, a fixing block 13 fixedly mounted on the connecting frame 12, and a fixing rod 14 inside the window frame 1. Two sets of symmetrically distributed fixing brackets 15 are sleeved on the fixing rod 14. Both sets of fixing brackets 15 are correspondingly set with the fixing block 13. An installation frame 17 is fixedly installed on the window frame 1. A retractable rod 18 is rotatably installed inside the installation frame 17. An insulation film 20 is sleeved on the retractable rod 18. A certain degree of heat insulation is achieved through the glass 3 with vacuum interlayer 4. The rotation angle of the ratchet 6 is limited by the two sets of pawls 8, thereby limiting the opening and closing angle of the window sash 2. This avoids the problem of the window sash 2 opening on its own when not needed and not being securely fixed. The two sets of pawls 8 are distributed correspondingly with the two sets of ratchet 6, and the two sets of pawls 8 respectively engage with the corresponding ratchet 6. Each of the two sets of rotating rods 7 is fitted with a first torsion spring 9. The two ends of the first torsion spring 9 are fixedly connected to the pawl 8 and the window frame 1, respectively. Each of the two sets of first racks 11 is correspondingly set with the first gear 10. Each of the two sets of first racks 11 is meshed with the corresponding first gear 10. Each of the two sets of fixing brackets 15 is movably engaged with the fixing block 13. A second torsion spring 16 is fitted on the fixing rod 14. The two ends of the second torsion spring 16 are fixedly connected to the two sets of fixing brackets 15 and the fixing rod 14, respectively. When the window sash 2 needs to be opened, the connecting bracket 12 is pulled to engage the fixing block 13 with the two sets of corresponding fixing brackets 15. Under the action of the second torsion spring 16, the two sets of fixing brackets 13 are engaged with the fixing block 13. Once the fixed bracket 15 secures the fixed block 13, the sliding of the two sets of connecting brackets 12 causes the two sets of first racks 11 to slide synchronously, thus limiting the position of the two sets of first racks 11. The two sets of first gears 10, which mesh with the two sets of first racks 11, drive the corresponding rotating rods 7 and pawls 8 to deflect synchronously, releasing the position limitation effect of the pawls 8 on the ratchet 6. At this time, the mounting rod 5 can rotate freely in the mounting frame 17, thereby driving the window sash 2 to rotate. After the fixed bracket 15 is released from securing the fixed block 13, the two sets of pawls 8 return to their original positions under the action of the first torsion spring 9, and continue to limit the rotation of the ratchet 6 and the mounting rod 5. The window sash 2 cannot rotate freely.
[0023] like Figure 4 and Figure 5As shown, a locking rod 21 is slidably installed inside the mounting frame 17. The left side of the locking rod 21 is movably engaged with the mounting frame 17. The locking rod 21 is fixedly connected to the end of the insulation film 20 away from the winding rod 18. Two sets of symmetrically distributed coil springs 19 are sleeved on the winding rod 18. The inner and outer ends of the coil springs 19 are fixedly connected to the winding rod 18 and the mounting frame 17, respectively. Two sets of symmetrically distributed brackets 22 are provided inside the mounting frame 17. The two sets of brackets 22 are movably engaged with the locking rod 21. A stop block 23 is fixedly sleeved on each set of brackets 22. Both sets of brackets 22 are slidably connected to the mounting frame 17 through the stop block 23. A spring 23 is sleeved on each set of brackets 22. The two ends of the spring 23 are fixedly connected to the stop block 23 and the mounting frame 17, respectively. A second rack 25 is fixedly installed on each set of brackets 22. A handle 26 is rotatably installed inside the frame 17. A third torsion spring 28 is sleeved on the handle 26. The two ends of the third torsion spring 28 are fixedly connected to the handle 26 and the mounting frame 17, respectively. A second gear 27 is sleeved on the handle 26. The second gear 27 is meshed with two sets of second racks 25. When it is necessary to enhance the heat insulation function of the aluminum alloy door and window, the handle 26 drives the second gear 27 to rotate, which, together with the two sets of second racks 25, pushes the two sets of brackets 22 outward synchronously. The bracket 21 is pulled so that the heat insulation film 20 covers the glass 3. The bracket 21 is engaged with the mounting frame 17. When the handle 26 is released, the two sets of brackets 22 automatically engage with the bracket 21 under the action of the third torsion spring 28 and the spring 23, thus completing the fixation of the bracket 21 and the heat insulation film 20.
[0024] This utility model provides a heat-insulating aluminum alloy door and window. The specific working principle is as follows: A certain degree of heat insulation is achieved through the glass 3 with a vacuum interlayer 4. The rotation angle of the ratchet 6 is limited by two sets of pawls 8, thereby limiting the opening angle of the window sash 2. This avoids the problem of the window sash 2 opening automatically and not being securely fixed when not needed. When the window sash 2 needs to be opened, the connecting bracket 12 is pulled, causing the fixing block 13 to engage with the two corresponding fixing brackets 15. Under the action of the second torsion spring 16, the two fixing brackets 15 secure the fixing block 13. The sliding of the two connecting brackets 12 drives the two sets of first racks 11 to slide synchronously, limiting the position of the two sets of first racks 11. The two sets of first gears 10, meshing with the two sets of first racks 11, drive the corresponding rotating rod 7 and pawls 8 synchronously. The ratchet 8 is deflected, releasing the positional constraint of the ratchet 6. At this time, the mounting rod 5 can rotate freely in the mounting frame 17, thereby driving the window sash 2 to rotate. After the fixing bracket 15 is released from fixing the fixing block 13, the two sets of ratchet 8 return to their original positions under the action of the first torsion spring 9, and continue to restrict the rotation of the ratchet 6 and the mounting rod 5. The window sash 2 cannot rotate freely. When it is necessary to enhance the heat insulation function of the aluminum alloy door and window, the handle 26 drives the second gear 27 to rotate, which, together with the two sets of second racks 25, pushes the two sets of brackets 22 outward synchronously. The bracket 21 is pulled so that the heat insulation film 20 covers the glass 3. The bracket 21 is engaged with the mounting frame 17. When the handle 26 is released, the two sets of brackets 22 automatically engage with the bracket 21 under the action of the third torsion spring 28 and the spring 23, thus completing the fixation of the bracket 21 and the heat insulation film 20.
