[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0027] like Figure 1 and Figure 2 As shown in the figure, this application provides a self-balancing mechanical hand-cranked lifting window system, including a window frame 1, a fixed sash 6, an upper opening sash 2, a lower opening sash 3, a self-balancing mechanism 4, and a drive mechanism 5; wherein, the fixed sash 6 is disposed inside the window frame 1 and located at the bottom of the window frame 1, serving to fix the railing and protect the safety of people inside. The upper opening sash 2 and the lower opening sash 3 are disposed inside the window frame 1 and located above the fixed sash 6, with the lower opening sash 3 located below the upper opening sash 2.

[0028] The drive mechanism 5 can drive the upper opening sash 2 to rise or fall. The lower opening sash 3, under the action of the self-balancing mechanism 4, can fall as the upper opening sash 2 rises and rise as the upper opening sash 2 falls, thereby realizing the opening and closing of the window sash.

[0029] The vertical frame of window frame 1 is provided with a U-groove. Both sides of the upper opening sash 2 and the lower opening sash 3 are embedded in the U-groove with a groove depth of 17mm, ensuring that the window sash moves up and down in the groove without coming out of the groove.

[0030] In one embodiment of this example, as Figure 3 and Figure 4 As shown, the self-balancing mechanism 4 includes a fixed pulley 41 fixed to the top of the vertical frame of the window frame 1, two steering wheels 42 fixed in the middle of the vertical frame of the window frame 1, and a steel cable 43 wound around the fixed pulley 41 and the steering wheels 42. A first lead screw 445 slide rod assembly 44 is provided at one end of the steel cable 43, and a second lead screw 455 slide rod assembly 45 is provided at the other end of the steel cable 43. The lower opening fan 3 is connected to the first lead screw 445 slide rod assembly 44, and the upper opening fan 2 is connected to the second lead screw 455 slide rod assembly 45.

[0031] Specifically, the first lead screw 445 slide rod assembly 44 includes a first slider 441, a second slider 442, a first roller 443 fixed on the first slider 441, a second roller 444 fixed on the second slider 442, and a first lead screw 445 that passes through and connects the first slider 441 and the second slider 442. The end of the steel cable 43 is connected to the first lead screw 445 by a first threaded sleeve 446.

[0032] The second lead screw 455 slide rod assembly 45 includes a third slider 451, a fourth slider 452, a third roller 453 fixed on the third slider 451, a fourth roller 454 fixed on the fourth slider 452, and a second lead screw 455 that passes through and connects the third slider 451 and the fourth slider 452. The end of the steel cable 43 is connected to the second lead screw 455 by a second threaded sleeve 456.

[0033] Both the fixed pulley 41 and the steering pulley 42 are made of high-quality 45# steel, with a bearing diameter of 25mm and a material of 316 stainless steel, bearing capacity exceeding 10KN. The steel cable 43 is an 8mm diameter stainless steel wire rope, with a single strand bearing capacity of 838KG and a single opening valve bearing capacity of 250KG, exceeding a safety factor of 3 times. The two ends of the steel cable 43 are connected to the lead screw using threaded sleeves to ensure a safe and reliable connection. The U-groove depth of the fixed pulley 41 and the steering pulley 42 is 10mm to ensure that the steel cable 43 will not disengage while running within the groove. The first roller 443 and the second roller 444 are SG15 rollers.

[0034] It should be noted that the self-balancing mechanism 4 in this application is provided in two sets, and the two sets of self-balancing mechanisms 4 are symmetrically arranged in the vertical frames of the window frame 1 on both sides to ensure the stability of the operation of the upper opening sash 2 and the lower opening sash 3.

[0035] In one embodiment of this example, as Figure 5 As shown, the drive mechanism 5 includes an upper machine 51 fixed to one side of the vertical frame of the window frame 1, a roller support 52 fixed to the other side of the vertical frame of the window frame 1, and a transverse transmission rod 53 connected between the upper machine 51 and the roller support 52. The transverse transmission rod 53 is rotatably connected to the roller support 52 and to the upper machine 51. A first gear 54 and a second gear 55 are fixed at both ends of the transverse transmission rod 53. A first rack 56 and a second rack 57 are vertically fixed on the vertical members on both sides of the upper opening fan 2. The first gear 54 meshes with the first rack 56, and the second gear 55 meshes with the second rack 57. A lower machine 58 is fixed on one side of the vertical frame of the window frame 1 and below the upper machine 51. A vertical transmission rod 59 is connected between the upper machine 51 and the lower machine 58. A rotating handle 581 is installed on the lower machine 58.

[0036] The lower unit 58 uses a 1.5-module 20-tooth hand-cranked steering mechanism with a 1:1 rotation ratio. The upper unit 51's mechanism uses a worm gear drive with a 20:1 transmission ratio, providing strong torque up to 400N. The outer shell is protected by thickened cast aluminum alloy. The gears are 2-module boss gears, and the rack is a matching 2-module rack. The transverse transmission rod 53 connects the boss gears on both sides in series, forming a concentric shaft to ensure simultaneous drive on both sides of the window sash and even force distribution.

[0037] When the handle 581 is turned to drive the lower unit 58, it drives the vertical transmission rod 59. The vertical transmission rod 59 drives the upper unit 51. The upper unit 51 transmits power to the horizontal transmission rod 53 through its internal structure. The horizontal transmission rod 53 drives the first gear 54 and the second gear 55 to rotate. The rotation of the first gear 54 and the second gear 55 drives the first rack 56 and the second rack 57 to move up and down, thereby driving the upper opening sash 2 to move. Since the upper opening sash 2 and the lower opening sash 3 are linked by the self-balancing mechanism 4, the lower opening sash 3 will move in the opposite direction to the movement of the upper opening sash 2, thus realizing the opening and closing of the window.

[0038] In one embodiment of this invention, the upper unit 51 has a self-locking function, and can only be driven by rotating the handle 581. This is irreversible, preventing the window sash from rotating dangerously under other forces. The upper unit 51 has a speed ratio of 20:1, which reduces effort during rotation and prevents excessively high speeds, ensuring smooth operation of the lifting window.

[0039] The top and bottom crossbeams of the upper opening fan 2 and the lower opening fan 3 are respectively connected to the crossbeam in the frame material and the upper crossbeam of the fixed fan 6 by hooks. This can limit the running distance of the upper opening fan 2 and the lower opening fan 3 and prevent the upper opening fan 2 from falling and the upper opening fan 2 and the lower opening fan 3 from colliding.

[0040] This application provides a self-balancing mechanical hand-cranked lifting window system. Rotating the handle 581 drives the lower mechanism 58, which in turn drives the vertical transmission rod 59. The vertical transmission rod 59 drives the upper mechanism 51, which in turn transmits power to the horizontal transmission rod 53 via its internal structure. The horizontal transmission rod 53 drives the first gear 54 and the second gear 55 to rotate. The rotation of the first gear 54 and the second gear 55 drives the first rack 56 and the second rack 57 to move up and down, thereby moving the upper opening sash 2. Since the upper opening sash 2 and the lower opening sash 3 are linked by the self-balancing mechanism 4, the lower opening sash 3 will move in the opposite direction to the movement of the upper opening sash 2, thus opening and closing the window. This application can meet the mechanical opening requirements of ultra-wide and ultra-large panel lifting windows, enhance the visual space, provide a transparent visual effect, have a large window opening area, and offer good ventilation.
