Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] Figure 1 The diagram illustrates the curtain structure of an embodiment. A curtain 1 includes: a roller 10, a support 20, a curtain body 30, and a horizontal rod 40. The roller 10 is mounted on the support 20. A first side 301 of the curtain body 30 is connected to the roller 10, and the opposite second side 302 is connected to the horizontal rod 40. Rotating the roller 10 causes the curtain body 30 to roll up / unroll. The horizontal rod 40 is connected to the curtain body 30 and moves in unison with it. A reinforcing structural layer 50 is provided on one side of the curtain body 30. The reinforcing structural layer 50 includes several continuously connected reinforcing units 501. Each reinforcing unit 501 includes a base layer 502 and a reinforcing layer 503. The base layer 502 and the reinforcing layer 503 are stacked to form a two-layer corner plate structure 5011. The apex edge 5012 of the corner plate structure 5011 serves as a support and is linearly connected to one side of the curtain body 30 at intervals.

[0035] To explain further, Figure 2 This is a schematic diagram of the shape of the reinforcing structure layer in an embodiment. Figure 3 This is a schematic diagram illustrating the connection between the reinforcing structural layer and the curtain body in an embodiment. The reinforcing structural layer 50 includes a plurality of continuously connected reinforcing units 501. Figure 2The reinforcing unit 501 includes a base layer 502 and a reinforcing layer 503, and the base layer and the reinforcing layer are laminated to form a two-layered angle plate structure 5011. The top corner edges 5012 of the angle plate structure 5011 are arranged at intervals. The top corner edges 5012 of the angle plate structure 5011 are linearly connected to the surface of the curtain body 30. Figure 3 The top corner edges 5012 of the angle plate structure 5011 are linearly connected to the surface of the curtain body 30.

[0036] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0037] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0038] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0039] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0040] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0041] Further explanation, the reinforcing layer 503 and the base layer 502 form a gusset structure shape, on one side of the gusset structure, the cross-sectional shape of the reinforcing layer 503 is not limited to the shape in the drawings of the present application, which can be rectangular, arc-shaped, trapezoidal, multiple curve-shaped, etc. The change of the cross-sectional shape of the reinforcing layer 503 will not have a greater impact on the inherent mechanism of improving the bending strength of the reinforcing structure layer 50.

[0042] Further explanation, the base layer 502 can be a multi-layer composite layer of more than two layers of material, and the reinforcing layer 503 can also be a multi-layer material layer of more than two layers, so the reinforcing unit 501 formed thereby can also be a multi-layer structure of three, four, five or more than two layers, which will not be exemplified one by one here; it can be known that to increase the bending strength of the reinforcing unit 501 composed of the base layer 502 and the reinforcing layer 503, more layers of the reinforcing layer 503 can be provided for adjustment, and for different bending deformation of the product, the reinforcing structure layer 50 with corresponding bending strength can be used to resist the bending deformation of the product, so that better flatness of the product can be achieved.

[0043] Further explanation, by setting the reinforcing structure layer 50 as a reinforcing unit 501 of at least two layers of structure including the base layer 502 and the reinforcing layer 503 connected continuously, the strength of the reinforcing unit 501 is enhanced by the reinforcing layer 503, the bending strength of the reinforcing structure layer 50 is improved, thereby overcoming the limitation of the single-layer gusset structure reinforcing structure layer 50 in improving the bending strength. Further, the reinforcing unit 501 is set as a gusset structure, and the top corner edges of the gusset structure have good straightness and bending resistance, so that the bending deformation strength in the direction of the gusset structure is further enhanced, and the continuously connected gusset structure can also be rolled in the direction orthogonal to the structure extension direction. By setting the gusset structure on the surface of the curtain body, the bending deformation strength of the curtain is greatly enhanced, thereby improving the flatness of the curtain, and the curtain can also be rolled, so that the problem of unevenness of the curtain after being rolled and unfolded on the curtain surface can be effectively solved.

[0044] Further explanation, the horizontal rod 40 has the functions of decoration and counterweight, and its shape is not unique, the cross section can be trapezoidal, rectangular or circular. The material of the horizontal rod 40 can be selected from metal materials such as iron and stainless steel, and can also be selected from plastic and glass fiber, etc. The two ends of the horizontal rod 40 can be provided with end covers for beautification, and the end covers can be increased by a small step for limiting the rolled curtain surface and shielding the gap. The connection between the roller 10, the horizontal rod 40 and the curtain body 30 can be any one of bonding, pressing, buckling, etc.

[0045] Preferably, Figure 4The side plate connection diagram of the gusset structure of the embodiment. In any two adjacent gusset structures 5011, the two side plates 5013 close to each other are connected to form a reverse gusset structure 5014 (the part in the dashed line box). Figure 4

[0046] Further explanation, the two side plates are connected, which can keep the gusset structure 5011 stable relative to the surface of the curtain body 30, avoid the two side plates of the gusset structure 5014 from shaking, keep the angle of the gusset structure 5014 stable, thereby improve the stability of the gusset structure 5014, and further ensure the straightness and bending resistance of the top corner edge, that is, ensure the flatness of the surface of the curtain body 30 in the direction of the top corner edge. The reverse gusset structure formed by the reverse gusset structure and the gusset structure can further improve the support stability. The reverse gusset structure and the surface of the curtain body 30 form a triangular stable structure, which can better improve the stability of the gusset structure, keep the angle of the gusset structure stable, ensure the straightness and bending resistance of the top corner edge, avoid the gusset structure from shaking relative to the surface of the curtain body, ensure the connection stability of the gusset structure and the surface of the curtain body, avoid the separation of the top corner edge and the curtain surface due to the shaking and twisting of the gusset structure, and thereby keep the curtain surface have long-term stable flatness under the action of the top corner edge.

[0047] Further, Figure 5 The relationship between the top corner edge of the reinforcing structure layer and the direction of the shaft axis of the embodiment is shown in the diagram. The top corner edges 5012 of all the gusset structures are parallel to each other and consistent with the direction of the shaft axis 100 (the direction indicated by the arrow in the middle). Figure 5

[0048] Further explanation, the top corner edges 5012 of the gusset structures 5011 are parallel to each other, which is beneficial to provide a more uniform support force, ensure the effective connection of the reinforcing structure layer 50 and the surface of the curtain body 30, and keep the flatness of the surface of the curtain body 30. For the window curtain, it is beneficial to uniformly wind and store, and avoid excessive local bending to form creases.

[0049] Further explanation, here the parallel top corner edges of the gusset structures can refer to the parallel top corner edges 5012 in the same plane of the gusset structure, or refer to the parallel top corner edges 5012 in space. At this time, the top corner edges 5012 of the gusset structure are not completely in the same plane, that is, the edges are parallel to each other in space.

[0050] Further, Figure 6 The size diagram of the side plate of the gusset structure of the embodiment. The wall width of one side plate of the gusset structure 5011 is denoted as D, and the wall width of the other side plate is denoted as d.

[0051] ​​The wall width of the two side plates of the gusset structure 5011 can be directly set to be equal, that is, D=d. In this way, the two side plates 5013 with equal wall width connected in series can make the gusset structure 5011 provide balanced bending resistance, avoiding the influence of the torsion of the gusset structure 5011 itself on the flatness of the curtain.

[0052] Further explanation and description, the wall width of the two side plates of the gusset structure 5011 described herein can be equal, that is, the wall width of the two side plates of all gusset structures 5011 on the reinforcing structure layer 50 is equal; or the wall width of the two side plates of all gusset structures on the reinforcing structure layer 50 is not completely equal, and only the wall width of the two side plates of the same gusset structure on the reinforcing structure layer 50 is equal.

[0053] Further explanation and description, a single gusset structure can be formed by bending the sheet material, and the sheet material is bent in one direction at a position line on the sheet material, and then the sheet material is bent in the opposite direction at a position line a certain distance away from the position line. In this way, the sheet material is continuously bent in two opposite directions at a certain interval to form the reinforcing structure layer.

[0054] Further explanation and description, the sheet material can use plastic materials such as polyethylene terephthalate (PET), polycarbonate (PC), and polymethyl methacrylate (PMMA). The plastic material can be a roll of plastic material that is continuously bent and then cut to the size of the curtain surface, and then adhered to the curtain surface by adhesive. Alternatively, the plastic material can be a single sheet that is continuously bent and then adhered to the curtain surface.

[0055] Further, Figure 7 The reinforcing layer in the embodiment is arranged on the base layer. As shown in FIG. a of Figure 7 The reinforcing layer 503 can be arranged on only one side of the base layer 502, as shown in FIG. a of Figure 7 The reinforcing layer 503 can be arranged on both sides of the base layer 502, as shown in FIG. b of

[0056] Further, Figure 8 The reinforcing structure layer 50 in the embodiment is arranged on the base layer 502. As shown in FIG. a of

[0057] The size of the reinforcing structure layer 50 is arranged to cover the surface area of the curtain 30. Specifically, the length G of the reinforcing structure layer 50 is equal to the length of the surface of the curtain 30, and the width K of the reinforcing structure layer 50 is equal to the width of the surface of the curtain 30.

[0058] Further explanation, the size of the reinforcing structure layer 50 fully covers the surface of the curtain 30, which can provide more complete bending resistance to the surface of the curtain 30, avoiding local deformation of the surface of the curtain without the reinforcing structure layer.

[0059] Further explanation, in the case of relatively flat edges on the surface of the curtain, the length G of the reinforcing structure layer 50 can be smaller than the length of the curtain 30, and the width K of the reinforcing structure layer 50 can be smaller than the width of the surface of the curtain 30. In this way, the weight of the curtain can be reduced, and the flatness requirement of the curtain can be more easily achieved.

[0060] Further, Figure 9 The size of the reinforcing unit of the embodiment is shown in the figure. The height of the reinforcing unit is h, and the thickness of the reinforcing unit is L. h can be set to 2mm-100mm, and L can be set to 2mm-50mm.

[0061] Further explanation, the height h and the thickness L of the reinforcing unit can determine the amount of material, the difficulty of forming, the bending resistance of the formed reinforcing structure layer, and the size of the rolled curtain. Therefore, under the premise of meeting the bending resistance of the reinforcing structure layer, appropriate height and thickness are beneficial to saving cost and avoiding the size of the rolled curtain being too large, which occupies a large space. When the height h of the reinforcing unit is less than 2mm and the thickness L is less than 2mm, the difficulty of forming the reinforcing structure layer is greatly increased, and the bending resistance of the formed reinforcing structure layer is relatively small, which is not conducive to resisting the bending deformation of the curtain surface after rolling. When the height h is greater than 100mm and the thickness L is greater than 50mm, the amount of material used and the size of the rolled curtain are greatly increased. The large amount of material used leads to the weight of the curtain being too heavy, and the large size of the rolled curtain is not conducive to the packaging, transportation and installation of the curtain, and also reduces the service life of the curtain.

[0062] Further, the height h of the reinforcing unit can gradually decrease / increase along one direction, and the thickness L can gradually increase / decrease along one direction.

[0063] In addition, the height h and the thickness L of the reinforcing unit can also change as follows: the height h changes along one direction, and the thickness L remains unchanged; the thickness L changes along one direction, and the height h remains unchanged.

[0064] Further, Figure 10 Another angle plate structure of the embodiment is shown in the figure. Two adjacent angle plates 5011 can also be connected by a connecting piece 601, which can be a flat plate or a curved plate. Figure 10 As shown in FIG. a, the cross-sectional shape of the connecting piece 601 can be linear; as shown in FIG. b, the cross-sectional shape of the connecting piece 601 can be arc-shaped, and of course it can also be other curved shapes. Figure 10 As shown in FIG. b, the cross-sectional shape of the connecting piece 601 can be arc-shaped, and of course it can also be other curved shapes.

[0065] The corner plate structures 5011 are connected by the connecting pieces, so as not to be isolated from each other, to form a whole, to realize the continuity of the reinforcing structure layer 50, to avoid the shaking / twisting of the corner plate structures 5011, to cause the reinforcing structure layer 50 to be separated from the surface of the curtain body 30, and to further maintain the long-term stable connection between the surface of the curtain body and the reinforcing structure layer and the flatness of the connection between the reinforcing structure layer and the surface of the curtain body.

[0066] Further explanation and description, the connecting piece 601 can be a two-layer structure as shown in the drawings, can also be a one-layer structure, or a three-layer, four-layer and more layer structure, mainly to make the corner plate structures not isolated from each other, to form a whole. Figure 10

[0067] Further, on the side of the reinforcing structure layer 50 away from the curtain body 30, a protective film layer can also be provided to cover the reinforcing structure layer 50, and the protective film layer is also rolled or unrolled together when the curtain body 30 is rolled or unrolled, so that the rolling or unrolling process of the curtain body 30 is more beautiful.

[0068] Further, Figure 11 For another window curtain structure diagram of the embodiment, the window curtain 1 further comprises a curtain box 70 and a side frame 80. The curtain box 70 is provided with a cavity for accommodating the roller 10, and covers the roller 10 to play a role of decoration and beauty of the window curtain. The curtain box 70 is provided with an opening, so that the curtain body can be stretched out of the opening when being stretched out, and can be rolled into the opening when being rolled. The side frame 80 is located on the two sides of the curtain body 30 which are not in the rolling direction of the roller 10. The side frame 80 and the curtain body 30 are connected through a guide rail 801. The two sides of the curtain body 30 are embedded in the guide rail 801 to be fixed. In this way, the two sides of the curtain body 30 can slide in the guide rail 801, so as to realize the rolling and stretching of the curtain body.

[0069] In addition, the setting of the side frame 80 and the guide rail 801, and the embedding and fixing of the curtain body 30 in the guide rail 801 can effectively enhance the stability of the window curtain when encountering wind.

[0070] Further explanation and description, the curtain box 70 can also be provided with a motor. The motor is connected with one end of the roller. The motor provides power for the rolling and unrolling of the whole window curtain. The motor drives the roller to rotate, so as to realize the control of the rolling and unrolling of the window curtain.

[0071] The shape of the curtain box 70 can be square, circular or polygonal, etc. The decorative edge (cover) of the curtain box 70 is generally used for hidden or embedded products. The shape of the decorative edge (cover) can be "L" shape, "T" shape or special shape. The connection between the parts in the curtain box 70 can be achieved by using screws, buckles or welding.

[0072] ​In summary, the curtain of the utility model, through setting the reinforcing structure layer 50 into the reinforcing unit of at least two layers of structure of the continuous connection including the base layer 502 and the reinforcing layer 503, the strength of the reinforcing unit 501 is enhanced through the reinforcing layer 503, the bending strength of the reinforcing structure layer 50 is improved, thereby overcoming the limitation of the bending strength improvement of the reinforcing structure layer of the single layer angle plate structure. Further set the reinforcing unit shape into the angle plate structure, and the top corner edge of the angle plate structure has good straightness and bending resistance, so that the bending deformation strength in the extension direction of the angle plate structure is further enhanced, and the continuously connected angle plate structure can also be rolled in the direction orthogonal to the structure extension direction, by setting the angle plate structure on the curtain surface, the bending deformation strength of the curtain can be greatly enhanced, thereby improving the flatness of the curtain, and the curtain can also be rolled, so that the unevenness problem of the bending deformation of the curtain after being rolled and unfolded on the curtain surface can be effectively solved.

[0073] The above is only the preferred embodiment of the utility model, and it should be pointed out that the above preferred embodiment should not be regarded as the limitation of the utility model, and the protection scope of the utility model should be limited by the range defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the utility model, and these improvements and refinements should also be regarded as the protection scope of the utility model.
