Description

Technical Field

[0001] The present invention relates to the technical field of building sunshade, and more particularly to a building energy-saving and heat-insulating sunshade device and a method of using the same. Background Art

[0002] To conserve energy and maintain heat, buildings are often equipped with energy-saving, heat-insulating shading devices. Especially in hot summer regions, shading significantly reduces building energy consumption and improves indoor living comfort. Architectural shading options include window shading, roof shading, wall shading, and landscaping shading. Of these shading measures, window shading is undoubtedly the most important.

[0003] After searching, the patent number CN215211963U discloses a building energy-saving, heat-insulating and sun-shading device, which states that "it includes a telescopic plate and a support frame, the support frame is arranged on one side of the telescopic plate, and the top of the support frame is rotatably connected to the top of the telescopic plate, the telescopic plate includes a rotating shell, a cable and an extension plate, the rotating shell is arranged on one side of the support frame, and the top of the rotating shell is rotatably connected to the top of the support frame, the extension plate is arranged on the inner side of the rotating shell and is slidably connected to the rotating shell, one end of the cable is fixedly connected to the upper end of the extension plate, and the other end of the cable is fixedly connected to the support frame, the support frame provides power to pull the cable, so that the extension plate is retracted into the inner side of the rotating shell, and the support frame is retracted at the same time..." From the content, it can be seen that this patent only uses the cable to retract the extension plate into the rotating shell. Since the cable is relatively soft, the extension plate is not stable, is not suitable for use in harsh environments, and has a limited scope of use. In view of this, we propose a building energy-saving, heat-insulating and sun-shading device and a method for using the same. Summary of the Invention

A building energy-saving, heat-insulating and sun-shading device according to claim 4, characterized in that: The folding bracket (7) comprises: A third fixing seat (701) is arranged on the outer side of the wall; A first connecting rod (702) is arranged on the third fixing seat (701); The first connecting rod (702) is rotatably connected to the third fixing seat (701), a stud (703) is provided on the rear side of the first connecting rod (702), and a tightening knob (704) is threadedly connected to the stud (703); a second connecting rod (705) arranged on the first connecting rod (702); Wherein, the second connecting rod (705) is rotatably connected to the first connecting rod (702) via a stud (703); a fourth fixing seat (706) arranged on the second connecting rod (705); The fourth fixing seat (706) is rotatably connected to the second connecting rod (705), and the fourth fixing seat (706) is arranged at the bottom of the sun visor (101).

6. A building energy-saving, heat-insulating and sun-shading device according to claim 5, characterized in that: A through hole (801) is provided on the rotating rod (8), and the rotating rod (8) is connected to the fastening knob (704) via the through hole (801).

7. A method for using the building energy-saving, heat-insulating and sun-shading device according to claim 6, characterized in that: The steps include: Step 1: The driving motor inside the chassis (201) can be controlled to operate by an external control device. After the control operation, the lifting seat (205), the first fixed seat (206), the long rod (207) and the second fixed seat (208) can be driven to move up and down by the screw rod (203). The moving long rod (207) can drive the sun visor (101) to rotate through the U-shaped plate (105), so that the angle of the sun visor (101) can be adjusted to provide shade; Step 2: The electric push rod (301) can be controlled to be extended and retracted through an external control device. The extended electric push rod (301) can drive the movable plate (303) to move along the direction of the sun visor (101) through the vertical plate (302) to adjust the sunshade range. At the same time, during the movement of the movable plate (303), the first brush (107) on the fixed plate (106) can continuously rub against the top of the movable plate (303) to clean the top of the movable plate (303), and the movable plate (303) will drive the second brush (304) to move to clean the top of the sun visor (101) for use; Step 3: The folding plate (4) can be rotated and unfolded. After unfolding, the round rod (502) can be inserted into the first insertion hole (104) of the sun visor (101), and then the screw rod (503) can be inserted into the second insertion hole (401) of the folding plate (4). After insertion, the nut (504) can be rotated to fix it, thereby fixing the folding plate (4) and increasing the shading range. Step 4: The rotatable support hook (602) is aligned with the upper fixing ring (601). After alignment, the support hook (602) can be hung on the upper fixing ring (601) to support the folding plate (4); Step 5: The fastening knob (704) can be tightened. After the fastening knob (704) is tightened, the first connecting rod (702) and the second connecting rod (705) can be fixed to achieve support for the sun visor (101); Step 6: The rotating rod (8) can be moved. When moving, the through hole (801) can be aligned with the fastening knob (704) and clamped. After clamping, the fastening knob (704) can be tightened or loosened for easy use.
