Description

Technical Field

[0001] This utility model belongs to the field of sunshade technology, specifically relating to a sunshade device for buildings. Background Technology

[0002] Sunshade devices are generally used to block sunlight, such as curtains and roller blinds, and are widely used in outdoor public places, commercial buildings, residential areas, and other places. They can provide sun protection and a cool environment.

[0003] Existing roller blinds typically hang naturally, raised or lowered by rotating rollers. When it's windy, the blinds are often blown around, causing the bottom edge to sway back and forth. This not only fails to provide adequate shade but also disturbs occupants and can even cause noise pollution from the bottom edge hitting the glass frame. Motorized roller blinds, in particular, can experience violent shaking if the rollers retract quickly when the bottom edge is swaying, potentially colliding with nearby people. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a building sunshade device that can ensure the stability of the roller blind and prevent it from swaying back and forth due to the wind.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a building shading device, comprising:

[0027] The present invention will be further described in detail below with reference to specific embodiments, so that those skilled in the art can more clearly understand the present invention.

[0028] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0029] Example 1

[0030] This embodiment provides a building shading device, including:

[0031] Framework 1. For example, see Figure 1 Frame 1 has a square-shaped structure and is adapted to the window.

[0032] Rotating cylinder 5, which is rotatably mounted at the top within frame 1. See, for example... Figure 2-3 The rotating cylinder 5 is arranged along the length of the frame 1. The rotating cylinder 5 extends from the inner wall of one side of the frame 1 to the inner wall of the other side, and the two ends of the rotating cylinder 5 are respectively fitted with the inner walls of the two sides of the frame 1 to ensure that the rotating cylinder 5 can rotate normally within the frame 1.

[0033] Motor 2 is used to drive the rotating drum 5 to rotate. For example, motor 2 can drive the rotating drum 5 to automatically rotate in both directions, that is, to automatically rewind or automatically unwind.

[0034] The blind curtain 7 has one end connected to the outer wall of the rotating cylinder 5, and the other end of the blind curtain 7 is provided with a first magnet 8. For example, see Figure 1-2 The blind 7 is a roller blind. The top of the blind 7 is connected to the outer wall of the rotating cylinder 5, and the top of the blind 7 is rolled up to the outside of the rotating cylinder 5. The bottom of the blind 7 is provided with a first magnet 8. The length of the blind 7 is the same as or similar to that of the rotating cylinder 5, so that the blind 7 covers the entire rotating cylinder 5. In this way, when the blind 7 is lowered, it can fully cover the inner side of the entire frame 1, achieving a good blocking effect.

[0035] The limiting frame 10 has sliding grooves 11 on both inner walls of the frame 1. The limiting frame 10 slides in conjunction with the sliding grooves 11. A second magnet 9 is provided inside the limiting frame 10, and the second magnet 9 magnetically attracts the first magnet 8. For example, see... Figure 2 The inner walls on both sides of the frame 1 are provided with vertical sliding grooves 11, and the two sliding grooves 11 are arranged opposite each other and at the same horizontal height. The limiting frame 10 is set horizontally, and the two ends of the limiting frame 10 are respectively slidably engaged with the two sliding grooves 11, that is, the limiting frame 10 can slide stably up and down in the sliding grooves 11.

[0036] Based on the above structure, the sunshade device provided in this embodiment has the bottom end of the shade curtain 7 connected to the limiting frame 10, so that the bottom end of the shade curtain 7 can only move up and down along the sliding groove 11, thereby improving the stability of the shade curtain 7 and preventing the bottom end of the shade curtain 7 from swaying back and forth due to the wind.

[0037] The limiting frame 10 can also act as a counterweight, so that the curtain 7 remains vertical during the rolling or lowering process, making the rolling or lowering process of the curtain 7 smoother and gentler.

[0038] The blind curtain 7 and the limiting frame 10 are magnetically secured, making disassembly and installation very convenient and applicable to a wide range of situations. For example, when the window is closed, the second magnet 9 can be separated from the first magnet 8, allowing the bottom of the blind curtain 7 to detach from the limiting frame 10, eliminating the need to bring the limiting frame 10 to a high position when rolling up the blind curtain 7. For example, for sealed windows without ventilation, the limiting frame 10 can be directly removed without dragging it up or down.

[0039] Example 2

[0040] Based on Embodiment 1, in this embodiment, the cross-section of the limiting frame 10 can be a U-shaped structure, similar to a box structure with an open top. The first magnet 8 is adapted to the limiting frame 10, and the planar dimension of the first magnet 8 is smaller than the planar dimension of the top opening of the limiting frame 10, ensuring that the first magnet 8 can smoothly enter the limiting frame 10.

[0041] The second magnet 9 is fixed inside the bottom of the limiting frame 10. That is, after the second magnet 9 and the first magnet 8 are magnetically attracted and fixed, they are both located inside the limiting frame 10. In this way, the limiting frame 10 can play a protective and concealing role, preventing the second magnet 9 and the first magnet 8 from being directly exposed to the outside, making the overall curtain 7 neater and more aesthetically pleasing.

[0042] Both the first magnet 8 and the second magnet 9 are strip-shaped structures. The second magnet 9 and the first magnet 8 are adapted to the blind curtain 7. For example, the second magnet 9 and the first magnet 8 are of the same or similar length to the blind curtain 7, making the blind curtain 7 more stable.

[0043] Example 3

[0044] Based on Example 1, see Figure 3 In this embodiment, a platform 4 is fixed on the side wall of the frame 1, and a motor 2 is mounted on the platform 4.

[0045] The sunshade device provided in this embodiment also includes a rotating shaft 3. Rotating holes are provided on both side walls of the frame 1. The rotating shaft 3 is rotatably mounted in the rotating holes via bearings, and the rotating shaft 3 is horizontally positioned. The rotating shaft 3 is coaxially fixed to the rotating cylinder 5, and the power output end of the motor 2 is coaxially fixed to the rotating shaft 3. Thus, the motor 2 can drive the rotating shaft 3 to rotate, thereby driving the rotating cylinder 5 to rotate, automatically retracting or lowering the sunshade curtain 7.

[0046] The sunshade device provided in this embodiment also includes a fixing ring 6, which is coaxially sleeved on the outside of the rotating shaft 3. The inner end of the fixing ring 6 is fixed to the rotating shaft 3, and the outer end of the fixing ring 6 is fixed to the rotating cylinder 5. Multiple fixing rings 6 are provided between the rotating cylinder 5 and the rotating shaft 3, and the multiple fixing rings 6 are evenly spaced along the axial direction of the rotating shaft 3.

[0047] Among them, the fixing ring 6 can connect the rotating shaft 3 and the rotating cylinder 5, and multiple fixing rings 6 are evenly spaced along the axial direction of the rotating shaft 3, which can play a stable supporting role and ensure that the structure of the rotating cylinder 5 is more stable.

[0048] The mechanisms, components, and parts in this invention that are not specifically described are all existing structures in the prior art and can be purchased directly from the market.

[0049] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," etc., indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
