Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to a foldable and liftable multi-functional upward-folding window. Background Technology
[0002] Traditionally, folding windows mostly use single-axis hinges or segmented folding structures, requiring manual operation of each window sash to open and close, a cumbersome and laborious process. Especially in high-rise buildings, users need to stretch their bodies to reach the top window sash, posing a safety hazard. In addition, the lack of an effective fixing mechanism after folding makes the window sash susceptible to deformation or accidental falling due to wind swaying, and the window frame and sash rely solely on ordinary sealing strips, which are prone to aging and air leakage after long-term use, affecting thermal insulation and sound insulation performance.
[0003] Existing folding window lifting mechanisms mostly rely on independent motors or complex pulley systems, which are costly and difficult to maintain. Manual lifting designs often result in high operating resistance due to unreasonable transmission structures. Furthermore, the locking between window sashes often uses pins or hooks, which require two hands to operate and lack stability. After folding, the large gap between the window sashes leads to a decrease in sealing performance. In addition, there is a lack of design to prevent accidental slippage, which poses a safety hazard. Therefore, we have proposed this multi-functional upward folding window that can be folded and lifted. Utility Model Content
[0004] The purpose of this invention is to provide a foldable and liftable multi-functional upward-folding 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 foldable and liftable multi-functional upward-folding window, including a mounting frame. Two grooves are symmetrically opened on the two inner sidewalls of the mounting frame. A folding hinge one is installed on the top of the inner side of the two grooves. An upper window frame is movably connected to the end of the folding hinge one. A folding hinge two is installed on the side of the upper window frame away from the folding hinge one. A lower window frame is movably connected to the end of the folding hinge two. Locking components are provided on the upper window frame and the lower window frame. An adjustment component is provided on the mounting frame.
[0006] Preferably, the adjusting assembly includes a movable block and a reciprocating screw. The groove has mounting slots on both inner sidewalls along the horizontal direction. The top of each of the two mounting slots is rotatably connected to a reciprocating screw. The movable block is threaded onto each of the two reciprocating screws. A crossbar is inserted into one side of the lower window frame. The two ends of the crossbar are rotatably connected to the two movable blocks respectively.
[0007] Preferably, the lower end of the mounting frame has an inner cavity, and two gears are symmetrically rotatably connected to the bottom two ends of the inner cavity. A toothed belt is meshed and wound around the two gears. The lower ends of the two reciprocating lead screws pass through the inner cavity, and the lower ends of the two reciprocating lead screws are respectively connected to the upper ends of the two gears.
[0008] Preferably, a mounting plate is connected to the lower end of the outer wall of the mounting frame. The mounting plate has a sliding groove extending into the inner cavity on the side away from the mounting frame. An operating rod is slidably connected to the sliding groove. One end of the operating rod extends into the inner cavity and is connected to a toothed belt. The mounting plate has two symmetrically arranged limiting grooves in the vertical direction on the inner side of the sliding groove. Two rollers are symmetrically rotatably connected to both sides of the operating rod, and the two rollers are respectively connected to the two limiting grooves.
[0009] Preferably, the inner sidewall of the groove is symmetrically connected with two sealing gaskets.
[0010] Preferably, the locking assembly includes a limiting rod, an installation opening is provided at the lower center of the upper window frame, a limiting rod is rotatably connected to the inner center of the installation opening, a connecting rod is connected to one end of the limiting rod, one end of the connecting rod passes through the upper window frame and is connected to a handle, and a slot is provided at the upper center of the lower window frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This foldable and liftable multi-functional upward-folding window uses a lever-driven toothed belt to drive two gears to rotate synchronously, which in turn drives two reciprocating screws to control the synchronous lifting and lowering of two movable blocks. This allows for one-handed operation, enabling the simultaneous folding or unfolding of the upper and lower window frames, significantly reducing the operating force. The limiting groove and roller form a sliding track to ensure the stability of the lever's movement trajectory and prevent the window frame from accidentally slipping. The crossbar passes through the lower window frame and rotates with the movable block, enhancing the structural rigidity during the lifting process and preventing skewing and jamming.
[0013] 2. This multi-functional folding window features a folding and lifting mechanism. The upper window frame's limiting rod is inserted into the lower window frame's slot via a rotating handle, achieving a rigid mechanical lock between the window sashes. This eliminates the risk of swaying during folding. The double sealing gaskets inside the groove fit tightly against the window frame, forming a double sealing barrier with the layered structure of the folded window sashes. This significantly improves airtightness and sound insulation. Furthermore, the coordinated movement of folding hinge one, folding hinge two, and the adjustment components ensures precise opening and closing of the window sashes, reducing friction wear and extending service life.

[0023] like Figures 1 to 6As shown, this embodiment of the foldable and height-adjustable multi-functional upward-folding window includes a mounting frame 1, which serves as the mounting carrier for the entire upward-folding window. Two grooves 2 are symmetrically formed on the two inner sidewalls of the mounting frame 1. A folding hinge 3 is mounted on the top of the inner side of each groove 2. The folding hinge 3 connects the mounting frame 1 to the upper window frame 4 and bears the main weight of the window sash. The end of the folding hinge 3 is movably connected to the upper window frame 4. A second folding hinge 5 is mounted on the side of the upper window frame 4 away from the first folding hinge 3. The second folding hinge 5 connects the upper window frame 4 to the lower window frame 6, enabling segmented folding of the window sash. The end of the second folding hinge 5 is movably connected to... A lower window frame 6 is connected to the upper window frame 4. Locking components are installed on both the lower window frame 6 and the upper window frame 4. An adjustment component is installed on the mounting frame 1. The adjustment component includes a movable block 7 and a reciprocating screw 9. The threaded groove of the reciprocating screw 9 is designed as a closed-loop structure. When the movable block 7 rises to the top or falls to the bottom, it automatically moves in the opposite direction. The groove 2 has mounting slots 8 on both inner walls along the horizontal direction. The top of each of the two mounting slots 8 is rotatably connected to the reciprocating screw 9. The movable block 7 is threaded onto each of the two reciprocating screws 9. A crossbar 22 is inserted on one side of the lower window frame 6. The crossbar 22 passes through the lower window frame 6 and is rotatably connected to the movable block 7, so that the lifting force is evenly distributed. The motion is evenly transmitted to the window sash to prevent jamming. The two ends of the horizontal bar 22 are rotatably connected to two movable blocks 7. An inner cavity 10 is opened inside the lower end of the mounting frame 1. Two gears 11 are symmetrically rotatably connected to the bottom ends of the inner cavity 10. The gears 11 symmetrically mesh with toothed belts 12 to ensure synchronous rotation of the double reciprocating screws 9. Toothed belts 12 are meshed and wound around the two gears 11. The toothed belts 12 are rigidly connected to the operating lever 14, converting linear motion into rotational motion. The lower ends of the two reciprocating screws 9 penetrate into the inner cavity 10, and the lower ends of the two reciprocating screws 9 are respectively connected to the upper ends of the two gears 11. The outer wall of the mounting frame 1... The lower end is connected to a mounting plate 13. The mounting plate 13 has a sliding groove 15 on the side away from the mounting frame 1, which extends through to the inner cavity 10. The sliding groove 15 is slidably connected to an operating rod 14. One end of the operating rod 14 extends into the inner cavity 10 and is connected to the toothed belt 12. The mounting plate 13 is located inside the sliding groove 15 and has two limiting grooves 16 symmetrically opened in the vertical direction. Two rollers 17 are symmetrically rotatably connected to both sides of the operating rod 14. The two rollers 17 are respectively connected to the two limiting grooves 16. Two sealing gaskets 23 are symmetrically connected to the inner wall of the groove 2, which form a noise reduction and waterproof sealing effect when the window is closed.
[0024] Specifically, when using this foldable and liftable multi-functional upward-folding window, by horizontally pulling the operating lever 14 on the mounting plate 13, the roller 17 rolls within the limiting groove 16, restricting the operating lever 14 to move only in the horizontal direction to prevent accidental disengagement. The operating lever 14 moves along the slide groove 15, driving the toothed belt 12 to move. The toothed belt 12 drives two gears 11 to rotate synchronously, driving two reciprocating screws 9 to rotate. The reciprocating screws 9 drive the movable block 7 to move linearly along the vertical direction of the mounting groove 8, and push it through the crossbar 22. The lower window frame 6 moves down or up, and the lower window frame 6 drives the upper window frame 4 through the second folding hinge 5. The angle of the first folding hinge 3 changes synchronously, and the window sash can be vertically opened to the maximum position. Alternatively, the upper window frame 4 and the lower window frame 6 can be stacked and folded. After the window sash is fully folded, the sealing gasket 23 on the inner side of the groove 2 tightly adheres to the surface of the window frame, forming a sealed barrier, which significantly improves air tightness and sound insulation. The coordinated movement of the first folding hinge 3, the second folding hinge 5 and the adjustment components ensures that the opening and closing trajectory of the window sash is accurate, reduces frictional wear and extends service life.
[0025] Furthermore, the locking component includes a limiting rod 19, which is a steel component. After rotation, it is embedded in the slot 21 of the lower window frame 6 and has high wind pressure resistance. An installation port 18 is opened at the center of the lower end of the upper window frame 4. The limiting rod 19 is rotatably connected to the center of the inner side of the installation port 18. One end of the limiting rod 19 is connected to a connecting rod. One end of the connecting rod passes through the upper window frame 4 and is connected to a handle 20. A slot 21 is opened at the center of the upper end of the lower window frame 6.
[0026] Furthermore, by grasping the handle 20 at the lower end of the upper window frame 4 and rotating the handle 20, the connecting rod is driven to disengage the limiting rod 19 from the slot 21 of the lower window frame 6, thus releasing the overlapping folded state of the upper window frame 4 and the lower window frame 6. This makes it safer to use and avoids instability of the upper window frame 4 and the lower window frame 6 in inclement weather. Rotating the handle 20 and inserting the limiting rod 19 into the slot 21 locks the upper window frame 4 and the lower window frame 6. This ensures that after the window sash is fully folded, the sealing gasket 23 inside the groove 2 tightly adheres to the surface of the window frame, forming a sealed barrier, significantly improving airtightness and sound insulation, and increasing the stability of the upper window frame 4 and the lower window frame 6.
[0027] The usage method of this embodiment is as follows: When using this foldable and liftable multi-functional upward folding window, by holding the handle 20 at the lower end of the upper window frame 4 and rotating the handle 20, the connecting rod is driven to disengage the limiting rod 19 from the slot 21 of the lower window frame 6. By horizontally pulling the operating rod 14 on the mounting plate 13, the operating rod 14 moves along the slide groove 15. The operating rod 14 drives the toothed belt 12 to move, and the toothed belt 12 drives the two gears 11 to rotate synchronously, driving the two reciprocating screws 9 to rotate. The reciprocating screws 9 drive the movable block 7 to move along the slide groove 15. The groove 8 moves vertically in a straight line, pushing the lower window frame 6 to move down or up via the crossbar 22. The lower window frame 6 drives the upper window frame 4 via the second folding hinge 5. The angle of the first folding hinge 3 changes synchronously, allowing the window sash to be vertically unfolded to its maximum position. Alternatively, the upper window frame 4 and the lower window frame 6 can be folded together. After the window sash is fully folded, the sealing gasket 23 inside the groove 2 tightly adheres to the surface of the window frame, forming a sealed barrier. After the operation is completed, rotate the handle 20, and the limit rod 19 is inserted into the slot 21 to lock the upper window frame 4 and the lower window frame 6.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
