Description

Technical Field

[0001] This utility model belongs to the field of rope winding technology, specifically relating to a rope winding device for wide-width louvered insulated glass. Background Technology

[0002] Venetian blind insulated windows are a widely used type of window. Based on the different mechanisms that drive the blinds, they are divided into manual and motorized types.

[0003] Motorized venetian blinds insulated glass units on the market consist of multiple slats, each connected in sequence to a tilting ladder rope and a retractable cord. These ropes are then connected to a winding mechanism. Specifically, the tilting ladder rope is connected to a tilting mechanism, which in turn is connected to a transmission component. When the transmission component rotates, it drives a tilting wheel within the tilting mechanism, which in turn rotates the tilting ladder rope, causing the slats to adjust their angle. The retractable cord is wound around a drum in the winding mechanism. The drum, driven by the transmission component, rotates to wind and release the cord, thus controlling the slats' movement. Therefore, the operational stability of the winding mechanism, including the tilting and retracting mechanisms, directly affects the performance of the motorized venetian blinds insulated glass unit.

[0004] The utility model patent with publication number CN213775192U discloses a modular flip-up rope reel for an electric louver. Although it achieves an integrated design of the flipping mechanism and the rope reeling mechanism, it still has the problem of being too tall overall. It needs to be matched with a wide frame, which does not meet the aesthetic needs of modern users and cannot be used in wide louvered insulated glass.

[0005] Therefore, there is an urgent need to design a rope winder for wide-width louvered insulated glass to solve the above problems. Utility Model Content

[0045] See Figure 2In this embodiment, the other end of the drive shaft 4 is also provided with a limiter 7. The limiter 7 is a conventional component used to control the lifting end point of the Venetian blind. It can monitor the movement range of the Venetian blind and send a signal when the limit is reached to stop the motor 3 from running, preventing the motor 3 from causing damage due to continuous movement. Since this technical measure is a conventional means, the specific structure and installation method will not be described in detail.

[0046] It also includes a rope winding mechanism 5, two lifting ropes 6, and two tilting ladder ropes 8.

[0047] See Figure 3 and Figure 4 The rope winding mechanism 5 includes a rope winding drum 51, a transmission screw 52, ​​a support and tilting seat 53, a rope guide slide 54, two fixed slide rods 55, and a support seat 56.

[0048] The support flipping seat 53 and the support seat 56 are respectively located on both sides of the rope drum 51. The two ends of the rope drum 51 are provided with first gear shafts 511. The outer ends of the two first gear shafts 511 are rotatably connected to the support flipping seat 53 and the support seat 56 respectively.

[0049] See Figures 5 to 9 The lower part of the support flipping seat 53 is provided with a first pull rope routing cavity 531, and a first guide rope wheel 532 is installed in the first pull rope routing cavity 531.

[0050] The transmission screw 52 is located above the rope drum 51. The two ends of the transmission screw 52 are provided with second gear shafts 521. The outer ends of the two second gear shafts 521 are rotatably connected to the support flipping seat 53 and the support seat 56, respectively. The gears of the first gear shaft 511 and the second gear shaft 521 on the same side mesh with each other.

[0051] See Figure 10 The upper part of the guide rope slide 54 is connected to the transmission screw 52, ​​the middle part of the guide rope slide 54 is sleeved with the rope drum 51, and the lower part of the guide rope slide 54 is sleeved with the fixed slide rod 55. The two ends of the fixed slide rod 55 are respectively fixed in the support flip seat 53 and the support seat 56. A second rope guide cavity 541 is provided below the guide rope slide 54, and a second guide rope wheel 542 is installed in the rope guide cavity 541.

[0052] The outer side of the support tilting base 53 is provided with a rotatable tilting wheel 533.

[0053] See Figure 8 The first gear shaft 511 in the middle is provided with a rope fixing hole 5111. The rope fixing hole 5111 is used to fix one end of the lifting rope 6. After the other end of the lifting rope 6 is wound around the winding drum 51, it passes through the second guide rope wheel 542 in the second rope routing cavity 541, and then through the first guide rope wheel 532 in the first rope routing cavity 531 downwards, passing through the blades in sequence, and is fixed to the bottom beam of the louver.

[0054] The support seats 56 of the two rope winding mechanisms 5 are arranged adjacent to each other. The drive shaft 4 enters from the flip wheel 533 on one side of the support flip seat 53, passes through the four first gear shafts 5111 in sequence, and exits from the flip wheel 533 on the other side of the support flip seat 53. The drive shaft 4 drives the flip wheel 533 and the first gear shaft 511 to rotate synchronously.

[0055] The upper end of the flip ladder rope 8 is wound around the flip wheel 533, and the lower end is fixed to the bottom beam of the venetian blind. The blades of the venetian blind 1 are sequentially overlapped on the flip ladder rope 8.

[0056] In this embodiment, both the first gear shaft 511 and the second gear shaft 521 are rotatably connected to the support flipping seat 51 via bearings.

[0057] See Figure 10 In this embodiment, a lead screw mounting hole 543 is provided on the upper part of the guide rope slide 54, and a lead screw sleeve 544 is embedded in the lead screw mounting hole 543. The lead screw sleeve 544 has an internal thread that matches the thread of the transmission lead screw 52.

[0058] See Figure 9 In this embodiment, the second gear shaft 521 has a lead screw mounting slot 5211 at its center, and the end of the transmission lead screw 52 is inserted into the lead screw mounting slot 5211.

[0059] See Figure 5 In this embodiment, the support flipping seat 53 is provided with a bracket 534, and the flipping wheel 533 is rotatably provided on the bracket 534.

[0060] Lifting principle: The motor 3 is electrically connected to the controller. The controller controls the output shaft of the drive motor 3 to rotate forward and backward, and the transmission shaft 4 to rotate forward or backward. This can increase or decrease the number of turns of the lifting rope 6 on the two rope drums 51, thus enabling the slats of the Venetian blind 1 to rise or fall. At the same time, the first gear 511 and the second gear 521 mesh and drive the screw 52 to rotate, causing the guide rope slide 54 to move on the screw 52.

[0061] The adjustable winding spacing of the lifting rope 6 on the rope drum 51 prevents uneven winding, tangling, rope biting, or even knotting of the lifting rope 6 on the rope drum 51.

[0062] Flipping principle: A small rotation of the drive shaft 4 can drive the flipping wheel 533 to rotate. The rotation of the flipping wheel 533 drives the flipping ladder rope 8 to rotate. The rotation of the flipping ladder rope 8 drives the Venetian blind 1 slats to flip, thereby adjusting the angle of the Venetian blind slats. When the Venetian blind slats are flipped to a certain angle, the flipping resistance of the Venetian blind 1 slats increases, and the flipping ladder rope 8 will slip relative to the flipping wheel 533. The rotation of the flipping wheel 533 will no longer drive the Venetian blind 1 slats to change angle.

[0063] The structure of the rope winding device has been further simplified, making it more compact and reducing the overall height. This allows for a lower window frame height and increased light transmission area. Two rope winding mechanisms are mounted on the drive shaft, with the support base serving as a load-bearing center, making it suitable for wide-pane louvered insulated glass. The rope winding guide slider has been improved to a three-point positioning system with a top lead screw and two bottom slide rails. Compared to the existing single lead screw positioning, the slider's operation is more stable, allowing for more precise and smooth rope winding. The integrated structure combining rope winding and ladder rope flipping is now more convenient to assemble and reduces production costs.

[0064] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
