Description

Technical Field

[0001] This utility model belongs to the field of residential sun shading, and in particular relates to an adjustable sun shading structure for residential windows. Background Technology

[0002] Architectural shading is a technical means of blocking or regulating solar radiation from entering a building by designing or installing shading facilities (such as sunshades, louvers, and green shading). Its core purpose is to improve the indoor thermal environment, reduce air conditioning energy consumption, and simultaneously ensure adequate lighting and visual comfort. Common forms include fixed (eaves, grilles) and adjustable (roller blinds, horizontal blinds), requiring optimized design based on building orientation and climate characteristics to achieve a balance between energy efficiency and aesthetics.

[0003] Roller blinds get their name from the way they are rolled up and down by a roller. They are widely used in formal settings such as offices, office buildings, banks, and schools. However, existing roller blinds hang down naturally when they are lowered, and the fabric is not restricted during use. Therefore, when the fabric is blown by the wind or pushed by external forces, it will swing and sway, which will affect the sunshade effect. In addition, the counterweight strip at the bottom can easily cause collision injuries to people when it swings. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable sunshade structure for residential windows that can restrict the curtain and prevent it from swinging.

[0005] The adjustable sunshade structure for the residential window includes two vertically arranged guide rods, which are symmetrically distributed at left and right intervals. A support plate is vertically fixed to the top of the two guide rods. A rotating shaft is horizontally installed between the two support plates, and a curtain is fixed on the rotating shaft. A driving device for driving the rotating shaft to rotate is provided on one of the support plates. Several guide blocks are evenly fixed on the left and right edges of the curtain. Guide grooves that are vertically connected and used for sliding of the guide blocks are opened on the inner sidewalls of the two guide rods. Positioning components for guiding and positioning the guide blocks during winding are provided on the two support plates.

[0006] Furthermore, the positioning component includes two clamping plates with an arc-shaped structure. The two clamping plates are hinged to the inner wall of the support plate and are symmetrically distributed with a front-to-back gap. A torsion spring is installed between the clamping plates and the support plate. The inner wall of the two clamping plates is provided with a slot for guiding and limiting the guide block.

[0007] Furthermore, a mounting rod is horizontally fixed between the two support plates, and a freely swinging sunshade plate is mounted on the mounting rod.

[0008] Furthermore, the light-shielding plate is made of an elastic material.

[0009] Furthermore, each guide rod is fixed with several mounting rings.

[0010] Furthermore, a connecting plate is horizontally fixed between the lower ends of the two guide rods.

[0011] Furthermore, a counterweight strip is horizontally fixed at the lower end of the curtain.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The drive unit causes the curtain to unfold and fall. The guide blocks on both edges of the curtain slide smoothly along the guide groove. Because the guide blocks are located in the guide groove, they restrain the left and right edges of the curtain, preventing the curtain from swinging and waving when blown by the wind or pushed by the outside. This prevents the curtain from swaying and causing collision injuries to nearby people, and avoids excessive gaps that could lead to light leakage, thus improving the light-blocking effect. When the shaft rewinds the curtain, the guide blocks slide smoothly upward along the guide groove. At the same time, two clamps press against the corresponding guide blocks. After the guide blocks pass through the guide groove, they enter and pass through the slot. The slot guides and positions the passing guide blocks, preventing them from moving laterally, thus ensuring that they are stably rewound on the shaft. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0015] Example This embodiment describes an adjustable sunshade structure for a residential window, such as... Figure 1 , Figure 3 and Figure 5 As shown, it includes two vertically arranged guide rods 1, which are symmetrically distributed with left and right intervals. Since the two guide rods 1 are distributed with left and right intervals, the side of the two guide rods 1 facing each other is the inner side, and the side facing away from each other is the outer side. A connecting plate 8 is horizontally fixed between the lower ends of the two guide rods 1, such as... Figure 1 and Figure 8 As shown, the connecting plate 8 is fixed to the lower end of the two guide rods 1. During installation, the connecting plate 8 is attached to the bottom of the window, and the two guide rods 1 are connected through the connecting plate 8, so that the two guide rods 1 and the connecting plate 8 are combined into a U-shaped structure. Each guide rod 1 has several mounting rings fixed on it, such as Figure 5 , Figure 6 and Figure 8 As shown, each guide rod 1 has three mounting rings evenly distributed along its length on both the front and rear sides. All mounting rings are flush with the outer side wall of the guide rod 1. During installation, two guide rods 1 are attached to the left and right side walls of the window, and a screw is inserted into each mounting ring. The mounting rings are fixed to the wall by the screws, thereby fixing the guide rod 1 to the side walls of the window. The tops of the two guide rods 1 are vertically fixed with support plates 2, such as... Figure 1 and Figure 9 As shown, the support plate 2 is vertically located on the outer side of the top of the guide rod 1; A pivot is horizontally installed between the two support plates 2, such as Figure 2 and Figure 9 As shown, the two support plates 2 have through holes, and the two ends of the rotating shaft are inserted into the through holes, allowing the rotating shaft to rotate freely. A curtain 5 is fixed on the pivot, such as Figure 6 As shown, one end of the curtain 5 is fixed to the pivot. When the pivot rotates in the forward and reverse directions, the curtain 5 will be rolled up or lowered, thereby adjusting the length of the curtain 5 to meet the window shading effect of different users. The curtain 5 is an existing product, which is usually made of cotton, linen, fiber and other materials. A counterweight 7 is horizontally fixed to the lower end of the curtain 5, such as... Figure 1 , Figure 8 and Figure 9As shown, the weight of the lower end of the curtain 5 is increased by the counterweight 7, and the lower end of the curtain 5 is pulled downward by the counterweight 7. One of the support plates 2 is equipped with a drive device 6 for driving the rotation of the shaft, such as... Figure 8 and Figure 9 As shown, in this embodiment, the driving device 6 uses a combination of a ball wheel and a torsion spring, which is a common product for existing roller blinds. The ball wheel is fixed to the shaft. By pulling the ball wheel, the ball wheel is rotated. At this time, the ball wheel drives the shaft to rotate, so that the curtain 5 can be moved up and down for adjustment. Of course, the driving device 6 can also be a motor. Several guide blocks 9 are evenly fixed on both sides of the curtain fabric 5, such as... Figure 5 , Figure 6 and Figure 9 As shown, all guide blocks 9 are evenly distributed at equal intervals along the left and right edges of the curtain fabric 5. In this embodiment, the guide blocks 9 are horizontal elongated cylindrical structures. When the curtain fabric 5 is rolled up on the rotating shaft, the guide blocks 9 on both sides of the curtain fabric 5 will be rolled up on both ends of the rotating shaft. When the cylindrical guide blocks 9 are stacked together by their special shapes, it is not easy for them to skew or slip. The inner walls of the two guide rods 1 are provided with guide grooves that are open vertically and used for sliding of the guide block 9, such as... Figure 5 , Figure 7 and Figure 9 As shown, the cross-section of the guide groove is T-shaped. When the curtain 5 is lowered from the pivot, the edge of the curtain 5 moves downward and inserts into the guide groove, and continues to move downward along the guide groove. At the same time, when the curtain 5 moves downward, it will drive the guide blocks 9 on it to enter the guide groove one after another, and continue to move downward along the guide groove. The guide groove guides and restricts the guide blocks 9. Because the guide blocks 9 are located in the guide groove, they will restrain the left and right edges of the curtain 5, preventing the curtain 5 from swinging and waving when blown by the wind or pushed by the outside, preventing the curtain 5 from causing collision injury to nearby people during the swinging process, avoiding the phenomenon of light leakage due to excessive gaps, and thus improving the light blocking effect. A mounting rod is horizontally fixed between the two support plates 2, and a freely swinging light-shielding plate 4 is threaded through the mounting rod. Figure 6 and Figure 8 As shown, the mounting rod is located above the curtain 5. With the support of its own weight, the swing end of the light-shielding plate 4 is attached to the rolled-up curtain 5. The curtain 5 blocks the gap between the curtain 5 and the top of the window, preventing excessive light from leaking out from the gap of the curtain 5. The light-shielding plate 4 swings to adapt to different diameters of the rolled-up curtain 5. The light-shielding plate 4 is made of materials such as rubber, silicone, and thermoplastic elastomer. Because the light-shielding plate 4 is elastic and deformable, it avoids the impact on the rolling movement when there is contact between the light-shielding plate 4 and the guide block 9. To elaborate further, such as Figure 1 , Figure 3 and Figure 7 As shown, this embodiment preferably includes two clamping plates 3, which have an arc-shaped structure. The two clamping plates 3 are hinged to the inner wall of the support plate 2, and are symmetrically distributed with a front-to-back gap. The clamping plates 3 are hinged to the inner wall of the support plate 2 via a pivot, and a pivot is horizontally fixed on the inner wall of the support plate 2. One end of the clamping plate 3 has a through hole for inserting the pivot, allowing the two clamping plates 3 to swing freely. Figure 6 As shown, they are symmetrically distributed, with the curtain 5 passing between the two clamping plates 3; a torsion spring 10 is installed between the clamping plate 3 and the support plate 2, as... Figure 7 and Figure 9 As shown, the torsion spring 10 is mounted on the pivot. An opening for placing the torsion spring 10 is provided at the end of the clamping plate 3. One end of the torsion spring 10 is fixed to the clamping plate 3, and the other end is fixed to the support plate 2. The torsion spring pushes the clamping plate 3 to swing in the direction of the pivot, causing the swinging ends of the two clamping plates 3 to press against the guide block 9. The two clamping plates 3, through their own swinging characteristics, adapt to being wound into guide blocks 9 of different sizes. The inner walls of the two clamping plates 3 are provided with slots for guiding and limiting the guide blocks 9, such as... Figure 3 , Figure 7 and Figure 9 As shown, when the two clamping plates 3 are pressed against the guide block 9, the guide block 9 will independently engage in the slot. When the curtain 5 is rolled up, the guide blocks 9 will successively enter and pass through the slot. The slot guides and positions the passing guide blocks 9 to prevent lateral movement, thereby stably rolling them up on the shaft. This whole assembly constitutes a positioning component for guiding and positioning the guide blocks 9 during winding. Of course, the positioning component can also use elastic sheets. The clamping plates 3 have an arc-shaped structure, and the two clamping plates 3 are hinged to the support plate 2. On the inner wall, two clamping plates 3 are symmetrically distributed at a front-to-back interval. Elastic sheets are fixed on the hinge ends of the two clamping plates 3, and the other ends of all the elastic sheets are fixed on the support plate 2. The inner walls of the two clamping plates 3 are provided with slots for guiding and limiting the guide block 9. By pushing the clamping plates 3 with the elastic sheets, the swing ends of the two clamping plates 3 are pressed against the guide block 9. The slots guide and position the passing guide block 9 to prevent the guide block 9 from moving laterally, thereby stabilizing the guide block 9 wound on the rotating shaft.

[0016] In actual use, during installation, the two guide rods 1 are first fixed to the walls on both sides of the window using mounting rings. When shading is needed, pulling down the bead chain rotates the bead wheel, which in turn rotates the shaft, causing the curtain 5 to unfold and fall. The guide blocks 9 on both edges of the curtain 5 slide smoothly along the guide grooves, and the counterweight 7 keeps the curtain 5 vertical. Because the guide blocks 9 are located within the guide grooves, they restrain the left and right edges of the curtain 5, preventing it from swaying or flapping in the wind or when pushed by external forces, and preventing damage to the surrounding area during the swaying of the curtain 5. To prevent collision injuries to nearby personnel and avoid excessive gaps that could lead to light leakage, thus improving the light-blocking effect; when it is necessary to roll up the curtain 5, pull the pull bead in the opposite direction, the bead wheel drives the rotating shaft to rotate, the rotating shaft rolls up the curtain 5, the guide block 9 slides smoothly upward along the guide groove, at the same time the two clamping plates 3 will press on the corresponding guide block 9, after the guide block 9 passes through the guide groove, it will enter and pass through the slot, the slot guides and positions the passing guide block 9 to prevent the guide block 9 from moving laterally, thus stably rolling it up on the rotating shaft.
