Description

Technical Field

[0001] This utility model belongs to the field of invisible screen door and window technology, specifically relating to a new type of windproof sheet structure and screen door and window. Background Technology

[0002] Invisible screen doors and windows are a common mosquito-proof structure. During use, the screen mesh and windproof sheet are sewn together, requiring a windproof sheet guide rail on the frame. Current technology places the windproof sheet guide rail on the side wall of the screen mesh track. While this guide rail can guide the windproof sheet, the vertical installation of the guide rail and the side sliding of the windproof sheet necessitate a specific height requirement for the guide rail. Taking doors and windows with vertically installed screen boxes as an example, the current windproof sheet structure generally results in the upper and lower frame heights being greater than the windproof sheet guide rail height. This makes it difficult to achieve a narrower bottom width and effectively reduce the height of the top and bottom frames. Furthermore, in strong winds, the screen mesh may tilt, causing one side to move away from or be compressed against the windproof sheet guide rail, increasing friction on the contact surface and leading to difficulty in sliding, thus affecting its effectiveness. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of windproof sheet structure and screen door / window with reasonable structural design and smooth operation.

[0005] The end of the mesh stretching opening of the gauze box is provided with a guide rail, and the guide rail is provided with a T-shaped slide rail groove;

[0006] The windproof sheet and the mesh are rolled up in a flat shape inside the gauze box. When the windproof sheet enters the T-shaped slide rail groove, the windproof sheet and the mesh are guided by the T-shaped slide rail groove to deform from a straight line into a T-shape and slide in the T-shaped slide rail groove.

[0007] A further preferred embodiment includes a first windproof guide member, which is disposed on the side of the guide rail near the yarn box and located on the yarn box seat. The surface of the first windproof guide member near the yarn box is an inclined guide surface, used to guide the windproof sheet into the T-shaped slide rail groove and make the windproof sheet and the yarn mesh form a T-shape in the T-shaped slide rail groove.

[0008] A further preferred embodiment includes a second windproof guide, wherein the second windproof guide is disposed on the side of the guide rail near the end of the yarn box, the second windproof guide is located on one side of the yarn mesh, and the surface near the yarn box is an inclined guide surface. The inclined guide surface of the second windproof guide and the inclined guide surface of the first windproof guide form a figure-eight shape and gradually narrow in the direction of the guide rail.

[0009] The windproof sheet is guided by the inclined guide surfaces of the first and second guide members of the windproof sheet and enters the T-shaped slide rail groove.

[0010] A further preferred embodiment is that the surface of the inclined guide surface is a plane, an arc surface, or a wavy surface.

[0011] A further preferred embodiment is that the vertical distance between the inclined guide surface of the second guide member of the windproof sheet and the windproof sheet is not higher than the vertical distance between the top wall of the transverse groove of the T-shaped slide rail groove and the windproof sheet.

[0012] A further preferred embodiment is that an L-shaped anti-scratch component is provided on the side of the guide rail near the end of the yarn box, the component is located on the other side of the yarn mesh, and the surface facing the windproof sheet is flat.

[0014] The limiting block is engaged in the limiting slot of the gauze box for limiting.

[0015] A further preferred embodiment is that the limiting block is a T-shaped block or a dovetail-shaped block.

[0016] A further preferred embodiment is that the width of the transverse groove of the T-shaped slide rail matches the width of the windproof sheet, and the width of the vertical groove of the T-shaped slide rail matches the width of the mesh.

[0017] A further preferred embodiment is that the top end of the second guide member of the windproof sheet has an integrally formed protrusion;

[0018] The top of the limiting block extends to the raised outer side.

[0019] A screen door / window includes a frame and a screen box disposed at one end of the frame, wherein a T-shaped groove is provided on the frame;

[0020] It also includes the aforementioned new windproof sheet structure;

The windproof sheet and mesh are rolled up in a planar shape inside the mesh box. When the windproof sheet enters the T-shaped slide rail groove, the T-shaped slide rail groove guides the windproof sheet and mesh to deform from a straight line into a T-shape and slide within the groove. This structure not only facilitates the storage of the entire mesh and windproof sheet inside the mesh box, but also allows them to form a T-shape within the T-shaped slide rail groove when pulled, thus reducing the frame height. Existing technologies have a frame height of 3cm, while this design reduces it to approximately 1cm, achieving an ultra-thin effect. Furthermore, the T-shaped windproof sheet and mesh structure effectively reduce friction with the T-shaped slide rail groove, ensuring smooth and effective movement even in strong winds. It also improves insect and dust prevention, making it highly versatile.

[0025] At the same time, the plane of the windproof sheet and the mesh can be gradually transformed into a T-shape, thereby improving the stability and effectiveness of use. After passing through the first and second guide members of the windproof sheet, the windproof sheet and the mesh also form a T-shape, which improves the effectiveness and reliability of wind protection.

[0026] It also provides a screen door and window that can ensure the ultra-thin effect of the upper and lower frame edges of the overall window, and also helps to improve the smoothness of the use of the screen door and window. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] See Figures 1 to 3b As shown, a novel windproof sheet structure includes a windproof sheet 2 disposed on the sliding edge of a mesh screen 1. The windproof sheet is generally made of a strip material with certain elasticity and hardness requirements, and can be made of plastic, steel strip, or other similar materials. The end of the mesh screen is fixed to the mesh screen pull rod 16. In this embodiment, when the mesh screen pull rod is pulled to move horizontally within the guide rail, the bottom windproof sheet will be guided and transformed into a T-shape with the mesh screen as it enters the T-shaped groove. In this embodiment, the above structure can achieve effective windproofing at the edge, improve dust and insect prevention, and since the windproof sheet is located at the edge of the mesh screen, the height of the frame edge can be reduced, achieving an ultra-thin effect, and ensuring smooth horizontal movement even in strong winds.

[0040] A guide rail 4 is provided at the end of the yarn stretching opening of the yarn box 3, and a T-shaped slide rail groove 5 is provided on the guide rail; the windproof sheet and the yarn are rolled up in the yarn box in a planar shape, and when the windproof sheet enters the T-shaped slide rail groove, the windproof sheet and the yarn are guided by the T-shaped slide rail groove to deform from a straight line into a T-shape and slide in the T-shaped slide rail groove.

[0041] Furthermore, it also includes a first windproof guide 17, located on the side of the guide rail near the yarn box end and on the yarn box base 19. The first windproof guide 17 can be integrally manufactured with the yarn box base or manufactured separately and fixed to the yarn box base. The surface of the first windproof guide 17 near the yarn box is an inclined guide surface, lower on the side near the yarn box and higher on the side away from the yarn box. The surface of the inclined guide surface can be flat, curved, or wavy, used to guide the windproof sheet into the T-shaped slide rail groove and make the windproof sheet and the yarn mesh form a T-shape within the T-shaped slide rail groove. The first windproof guide 17 deforms the outer side of the windproof sheet as it passes through, gradually making it perpendicular to the yarn mesh, ensuring effectiveness and reliability in use. Furthermore, a second windproof guide 6 is provided at the connection between the guide rail and the yarn box. The second windproof guide 6 is located on the side of the guide rail near the yarn box, on the side of the yarn mesh. The surface of the second windproof guide 6 near the yarn box is an inclined guide surface. The inclined guide surface of the second windproof guide 6 and the inclined guide surface of the first windproof guide 6 form a figure-eight shape and gradually narrow in the direction of the guide rail. The windproof sheet is guided by the inclined guide surfaces of the first and second windproof guide 6 and enters the T-shaped slide rail groove. The surface of the inclined guide surface can be a flat surface, an arc surface, or a wavy surface. In this embodiment, the second windproof guide 6 can be set on the guide rail or on the yarn box.

[0042] During processing, the vertical distance between the inclined guide surface of the second guide member of the windproof sheet and the windproof sheet is no higher than the vertical distance between the top wall of the transverse groove of the T-shaped slide rail and the windproof sheet. The windproof sheet is guided by the inclined guide surface of the second guide member and enters the T-shaped slide rail groove. Under the guidance of the inclined guide surface, the windproof sheet and the mesh form a T-shape. Furthermore, in this embodiment, an L-shaped anti-scratch component 18 is also provided on the side of the guide rail near the mesh box. This component is located on the other side of the mesh, and the surface facing the windproof sheet is flat. It is used to press down the windproof sheet that is upturned on the other side of the mesh to avoid the windproof sheet directly rubbing against the alloy track. Through the above structure, smooth translation can be guaranteed, and damage to the windproof sheet can be prevented, ensuring the effectiveness and reliability of insect and dust prevention. The height of the inclined guide surface away from the mesh box is low, which can prevent the windproof sheet from loosening or falling off, ensuring the effectiveness of guidance.

[0043] In practical applications, the outer surface of the second guide member of the windproof sheet is integrally formed with a limiting block 8; the limiting block is locked into the limiting slot 9 of the gauze box for limiting. Through the above structure, after assembly, the position of the second guide member of the windproof sheet can be guaranteed to be stable and reliable, preventing tilting or displacement, and also preventing damage, which is also conducive to ensuring the guiding effectiveness of the windproof sheet.

[0044] In practical applications, the limiting blocks are T-shaped or dovetail-shaped. This improves assembly effectiveness, prevents loosening or displacement, and facilitates disassembly and assembly.

[0045] In this embodiment, the horizontal groove width of the T-shaped slide rail groove matches the width of the windproof sheet, and the vertical groove width of the T-shaped slide rail groove matches the width of the mesh. This structure ensures the smooth and effective use of the mesh and windproof sheet.

[0046] Furthermore, in practical applications, the top of the second guide member of the windproof plate is integrally formed with a protrusion 10; the top of the limiting block extends to the outer side of the protrusion. Through the above structure, the height of the limiting block can be increased, ensuring strength and assembly effectiveness during assembly. The height of the protrusion can be machined and set as needed.

[0047] This utility model has positive effects: Its structure is reasonably designed, including a windproof sheet placed at the edge of the mesh, and a T-shaped slide rail groove on the guide rail. The windproof sheet and mesh are rolled up in a planar shape inside the mesh box. When the windproof sheet enters the T-shaped slide rail groove, the T-shaped slide rail groove guides the windproof sheet and mesh to deform from a straight line into a T-shape and slide within the groove. This structure not only facilitates the storage of the entire mesh and windproof sheet inside the mesh box, but also allows them to form a T-shape within the T-shaped slide rail groove when pulled, thus reducing the frame height. Existing technologies have a frame height of 3cm, while this design reduces it to approximately 1cm, achieving an ultra-thin effect. Furthermore, the T-shaped windproof sheet and mesh structure effectively reduce friction with the T-shaped slide rail groove, ensuring smooth and effective movement even in strong winds. It also improves insect and dust prevention, making it highly versatile.

[0048] At the same time, the plane of the windproof sheet and the mesh can be gradually transformed into a T-shape, thereby improving the stability and effectiveness of use. After passing through the first and second guide members of the windproof sheet, the windproof sheet and the mesh also form a T-shape, which improves the effectiveness and reliability of wind protection.

Thus, the windproof sheet and the screen are in straight contact and can slide within the screen guide groove, ensuring effective and smooth use. In this embodiment, the screen box can be installed on the side of the frame to achieve left-right extension, or on the top edge of the frame to achieve up-down extension.

[0051] Furthermore, in this embodiment, the screen box is provided with a limiting groove, and the limiting block of the second guide member of the windproof sheet is locked in the limiting groove. Moreover, a rubber inner rail 13 is provided in the T-shaped groove; this can reduce the resistance of the screen and improve the mosquito and dust prevention effects, and the rubber inner rail is provided with a T-shaped groove.

[0052] In practical applications, the second guide member of the windproof sheet is provided with a limiting protrusion 14; the surface of the frame is provided with a limiting slot 15 that mates with the limiting protrusion; during assembly, the frame and the windproof guide member are combined and the limiting protrusion is inserted into the limiting slot. This structure ensures the positional accuracy of the connection between the second guide member of the windproof sheet and the frame, prevents tilting or displacement, and improves installation stability and reliability.

[0053] A type of screen door and window can also ensure the ultra-thin effect of the upper and lower frame edges of the overall window, and also help improve the smoothness of the use of the screen door and window.

[0054] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
