Technical Field

[0001] The utility model relates to the technical field of rolling curtain devices, in particular to a steel wire guided windproof rolling curtain. Background Art

[0002] Roller blinds are a type of covering used for doors and windows. They are made of a variety of materials depending on the needs of use. Commonly used materials include cloth, plastic, and metal. Their main functions include shading, heat insulation, privacy protection, and beautification and decoration. They are widely used in windows in homes such as bedrooms, living rooms, studies, and kitchens, commercial places such as offices, shops, and restaurants, and some public places such as schools, hospitals, and libraries.

[0003] When you need both ventilation and shading, you need to open the window and then lower the roller blinds. However, the texture of the roller blinds is relatively soft. When the window is ventilated, air will flow through the window. At this time, the shading roller blinds will swing randomly under the blowing of the air flow. On the one hand, the shading effect is affected. On the other hand, long-term shaking will also produce noise, and in severe cases, the roller blinds will be damaged. Utility Model Content

[0026] Example 1

[0027] See also Figure 1-5 A wire-guided windproof roller shutter comprises a top beam 1 connected to the top of an installation opening, a curtain 2 provided in the top beam 1, and a driving structure for rolling up the curtain 2 built into the top beam 1, a bottom beam 10 provided at the bottom end of the curtain 2, edge guide ropes 7 provided near both ends of the top beam 1, a tensioning beam 3 provided under the edge guide rope 7, the tensioning beam 3 connected to the bottom end of the installation opening, edge pulleys 12 provided near both ends of the tensioning beam 3, the edge pulleys 12 rollingly cooperating with the edge guide rope 7, a first tensioning assembly 8 for tightening the edge guide rope 7 provided on the tensioning beam 3, and a guide assembly 6 for slidingly cooperating with the edge guide rope 7 provided on the side of the bottom beam 10;

[0028] In the present invention, an edge guide rope 7 and a guide assembly 6 are provided. The edge guide rope 7 is connected between the top beam 1 and the tensioning beam 3 and is kept taut by the first tensioning assembly 8. The edge guide rope 7 is then connected to the bottom beam 10 by the guide assembly 6. When the curtain 2 is released, the curtain 2 moves downward under the drive of the bottom beam 10. When the air flow blows, the taut edge guide rope 7 supports and limits the bottom beam 10 and the curtain 2, thereby preventing the curtain 2 from shaking at will, preventing the shading effect of the curtain 2 from being affected, and preventing the curtain 2 from being easily damaged due to long-term shaking.

[0029] The guide assembly 6 can connect the bottom beam 10 with the edge guide rope 7, so that the bottom beam 10 always moves along the edge guide rope 7 through the guide assembly 6 when rising, falling, or standing still. The tightened edge guide rope 7 stabilizes the position of the bottom beam 10, so that the bottom beam 10 can move stably and avoid being disturbed by airflow.

[0030] It should also be further explained that the device can be set at an angle using the taut edge guide rope 7, that is, the bottom beam 10 can slide obliquely along the inclined edge guide rope 7, so that the device can be installed on some inclined windows, such as skylights on sloping roofs, further increasing the scope of application of the device.

[0031] A chute 5 is provided on the bottom beam 10 at a position corresponding to the guide assembly 6, and the guide assembly 6 is arranged in the chute 5;

[0032] By setting the slide groove 5, the slide groove 5 can limit the position of the guide component 6, so that the guide component 6 can be set to any position on the bottom beam 10 through the slide groove 5, which makes it easy for the guide component 6 to adjust its own position according to the position of the edge guide rope 7.

[0033] The guide assembly 6 includes a connecting plate 601 that is slidably engaged with the chute 5. Bolts 602 are provided on both sides of the connecting plate 601. The other end of the bolt 602 passes through the connecting plate 601 and is in contact with the inner wall of the chute 5. A washer 604 is provided between the bolt 602 and the connecting plate 601. A guide sleeve 603 is provided on the connecting plate 601, and the guide sleeve 603 is slidably engaged with the edge guide rope 7.

[0034] By setting the connecting plate 601 and the bolt 602, the connecting plate 601 can carry the guide sleeve 603, so that the guide sleeve 603 can move along the edge guide rope 7 and standardize the movement path of the bottom beam 10. In addition, the connecting plate 601 can slide in the slide groove 5 on the bottom beam 10 to achieve the purpose of adjusting its own position. When fixing, the bolt 602 is tightened so that the bottom surface of the bolt 602 fits with the bottom beam 10, and a supporting force is applied, so that the connecting plate 601 fits in the slide groove 5 under the action of the supporting force, so that it fits and is fixed with the slide groove 5. In this way, there is no need to open the bolt 602 hole on the bottom beam 10, which ensures the sealing performance of the bottom beam 10 and prevents the inside of the bottom beam 10 from being eroded by wind and rain.

[0035] The first tensioning assembly 8 includes a threaded member 801, with a first threaded rod 802 and a second threaded rod 803 connected to the ends of the threaded member 801, respectively. The end surface of the first threaded rod 802 is provided with a hook 804, and the end surface of the second threaded rod 803 is provided with a connecting ring 805. The connecting ring 805 and the hook 804 are respectively connected to the ends of the edge guide rope 7;

[0036] By setting the threaded member 801, when the threaded member 801 is rotated forward, the threaded member 801 will move the first threaded rod 802 and the second threaded rod 803 connected at both ends inward, so that the first threaded rod 802 pulls the edge guide rope 7 through the hook 804, and the second threaded rod 803 pulls the edge guide rope 7 through the connecting ring 805, so that the edge guide rope 7 is tightened, which facilitates the installation of the equipment.

A central pulley 13 is provided at the center of the tensioning beam 3 in rolling engagement with the central guide rope 4.

[0039] By setting a center guide rope 4, in this embodiment, a center guide rope 4 is added at the center position of the top beam 1 and the tensioning beam 3, and the guide tensioning and second tensioning components 9 are installed accordingly. The center guide rope 4 is used to further support the center position of the bottom beam 10, so that the movement process of the bottom beam 10 is more stable and the windproof ability is stronger.

[0040] The second tensioning assembly 9 includes a fixing plate 901, which is connected to the tensioning beam 3. A support plate 902 is provided on the fixing plate 901. A third threaded rod 904 is slidably provided in the support plate 902. One end of the third threaded rod 904 is connected to a nut 903, and the other end is connected to the central guide rope 4.

[0041] By setting a third threaded rod 904 and a nut 903, one end of the third threaded rod 904 is connected to the center guide rope 4, and the other end is connected to the nut 903. By rotating the nut 903, the third threaded rod 904 can be pulled, and the third threaded rod 904 pulls the center guide rope 4, so that the center guide rope 4 is tightened.

[0042] A cover plate 11 is provided on the tension beam 3, and through holes are provided on the cover plate 11 at positions corresponding to the center guide rope 4 and the edge guide rope 7;

[0043] By setting the cover plate 11, the cover plate 11 can cover the tensioning beam 3 and protect the first tensioning component 8 and the second tensioning component 9 on the tensioning beam 3, prevent dust or rainwater from eroding the first tensioning component 8 and the second tensioning component 9, and protect the long-term stable operation of the equipment.
