Abstract
Description
Technical Field
[0001] This utility model relates to the field of public facilities technology, specifically to a windproof and rainproof device for public seats. Background Technology
[0002] Public seating is a feature placed in public places for people to rest and socialize. It is typically long and narrow, and is found in areas such as lawns, squares, and parks. Public seating serves as a tool for public activities; it is the material basis for defining the function of public spaces and an important factor in expressing their form.
[0003] Outdoor public seating is made from a variety of materials, including wood, stone, metal, and glass. Wood has a natural texture and a comfortable feel, and is often used in natural environments such as parks. However, wood is difficult to maintain, is prone to rot under prolonged exposure to wind and sun, and is difficult to dry quickly after being soaked in water, affecting its continued use. While fixed rain shelters exist in existing technology, in practical use, they are difficult to integrate with the environment. In parks and green areas that emphasize nature, the rain shelters also block sunlight, affecting the user experience in winter. Therefore, there is room for technological improvement. Utility Model Content
[0004] This invention aims to solve the aforementioned technical problems that fixed rain shelters are difficult to integrate into natural environments, affect the experience of sunlight in winter, and are inconvenient to adjust, by providing a windproof and rainproof device for public seats.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a windproof and rainproof device for public seats, including two uprights, both of which are fixedly connected to the back panel of the public seat through metal connectors; a top plate is welded to the top of the uprights, and a rectangular groove is provided on the top plate;
[0006] A rain shield is hinged to the top plate, and the rain shield can cover the rectangular groove; a driving structure is provided between the bottom surface of the rain shield and the top plate;
[0007] A mesh fabric is movable on the top plate, and the mesh fabric can cover the rectangular groove when unfolded; the front and rear ends of the mesh fabric are respectively provided with a movable strip that can move on the top plate and a fixed strip that is fixed on the top plate; a linkage structure is provided between the movable strip and the rain shield.
[0008] Furthermore, the drive structure includes mounting boxes located below the top plate and near both sides. Each mounting box has an electric push rod hinged to its bottom surface, and the output end of each electric push rod extends out of the mounting box and is hinged to the rain shield.
[0009] Furthermore, the top plate and near both sides are provided with through slots that allow the electric push rod to pass through; the bottom surface of the mounting box is a grid plate.
[0010] Furthermore, the linkage structure includes symmetrical guide wheels on the top plate and located in front of the rectangular groove; fixed ears on the moving bar near both ends; and pull ropes fixed to the bottom surface of the rain shield near both ends, with each pull rope passing around the guide wheel and connected to the corresponding fixed ear.
[0011] Furthermore, a limiting slider is provided below the moving bar and near both ends, and a limiting groove is provided on the top plate that can be slidably connected with the limiting slider. A sliding rod is provided in the limiting groove that can pass through the limiting slider and be slidably connected with it; a spring is provided on the side of the limiting slider away from the guide wheel and outside the sliding rod.
[0012] Furthermore, the pull rope is a metal rope.
[0013] The advantages of this utility model compared with the prior art are as follows:
[0014] The rain shelter can be covered or uncovered according to actual needs, and can be flipped up and retracted when sunlight is needed. When retracted, the rectangular groove is exposed, which can increase the area for wind to pass through on windy days. This avoids the problem of fixed rain shelters increasing wind resistance and causing the shelter to tip over.
[0015] When the rain shelter is retracted, the mesh fabric will automatically extend, which can intercept litter such as fallen leaves, insects, and bird droppings while reducing the obstruction of sunlight, thus improving the comfort of public seating. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] Example 1, in conjunction with Appendix Figure 1 A windproof and rainproof device for public seats includes two uprights 1, which are fixed to the back panel of the public seats by metal connectors. The metal connectors can be clamps or directly fixed by expansion bolts to ensure the stability of the uprights and the structure described below.
[0023] Combined with appendix Figure 1 , 2 A top plate 2 is welded to the column 1, and a rectangular groove 3 is provided on the top plate 2; the top plate 2 mainly serves to support the rain shield 4 and the mesh 8 mentioned below.
[0024] Combined with appendix Figure 1 , 2 3, 4. A rain shield 4 is hinged to the top plate 2, and the rain shield 4 can cover the rectangular groove 3. A driving structure is provided between the bottom surface of the rain shield 4 and the top plate 2. Specifically, the driving structure includes a mounting box 5 located below the top plate 2 and near both sides. An electric push rod 6 is hinged to the bottom surface of the mounting box 5. The output end of the electric push rod 6 extends out of the mounting box 5 and is hinged to the rain shield 4. The mounting box 5 is used to provide space for the electric push rod 6 so that after its actuating end drives the rain shield 4 to flip down, the electric push rod 6 can enter the mounting box 5 to avoid blocking the rain shield 4.
[0025] Based on the above structure, the top plate 2 is provided with through slots 7 on both sides to allow the electric push rod 6 to pass through; the bottom surface of the mounting box 5 is a mesh plate, which is used to drain water after the mounting box 5 is filled with water to avoid water accumulation.
[0026] Combined with appendix Figure 1 , 2 3, 4, A mesh 8 is movable on the top plate 2. When the mesh 8 is unfolded, it can cover the rectangular groove 3. The front and rear ends of the mesh 8 are respectively provided with movable strips 9 that can move on the top plate 2 and fixed strips 10 that are fixed on the top plate 2.
[0027] Based on the above structure, a linkage structure is provided between the movable strip 9 and the rain shield 4. Specifically, the linkage structure includes symmetrical guide wheels 11 located on the top plate 2 in front of the rectangular groove 3; fixed ears 12 are provided on the movable strip 9 near both ends; pull ropes 13 are fixedly connected to the bottom surface of the rain shield 4 near both ends, and the pull ropes 13 pass around the guide wheels 11 and are connected to the corresponding fixed ears 12; the pull ropes 13 are metal ropes; thus, in the above structure, when the electric push rod 6 drives the rain shield 4 to open upward, the rain shield 4 drives the pull ropes 13 and the fixed ears 12 to move, thereby driving the movable strip 9 to move, gradually opening the mesh 8 to cover the rectangular groove 3; the mesh 8 has mesh and a certain degree of permeability, which can intercept fallen leaves, insects, bird droppings and other garbage while reducing the obstruction of sunlight, thus improving the comfort of public seats.
[0028] Based on the above structure, a limiting slider 14 is provided below the moving strip 9 and near both ends. A limiting groove 15 is provided on the top plate 2, which can be slidably connected to the limiting slider 14. A sliding rod 16 is provided in the limiting groove 15, which can pass through the limiting slider 14 and be slidably connected to it. A spring 17 is provided on the side of the limiting slider 14 away from the guide wheel 11 and outside the sliding rod 16. The limiting slider 14, the limiting groove 15, and the sliding rod 16 are used to limit the moving strip 9, so that it only moves on the top plate 2 and does not come off upward. The spring 17 causes the moving strip 9 to move towards the direction closer to the fixed strip 10 after the moving strip 9 loses tension, that is, when the rain shield 4 flips down. This can prevent the rain shield 4 from directly pressing on the mesh cloth 8, causing the accumulated impurities on it to be squeezed and fall off. When it is retracted, the mesh cloth 8 can be pocketed to collect impurities, making it less likely for the impurities to be squeezed and broken and fall off.
[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
