Description

Technical Field

[0001] The utility model relates to the field of sunshade equipment, in particular to a stackable and foldable louver blade structure. Background Art

[0002] At present, most of the louver grilles on the sun room are fixed louver blades, which can only be opened and closed by flipping in place, and all louver blades cannot be moved and stacked to one side to form a better landscape effect and ventilation effect. For this reason, a louver grille that can stack louver blades to one side has emerged, such as the technical solution disclosed in the Chinese patent literature, with patent application number 202111668959.9 and the name "a stackable flip louver grille", which mainly includes a slide rail, a plurality of blades, and a synchronous limit rod, wherein the slide rail is provided with a power assembly, the blade is provided with a power shaft and a parallel shaft, and the blades are connected together by a steel cable, each blade is slidably set on the slide rail through a power shaft, and the power shaft of the first blade in the forward direction is hinged on the power assembly, and each blade is slidably set on the synchronous limit rod through a parallel shaft. When in use, the first blade is driven to slide on the slide rail by the power assembly, and then the subsequent blades are linked to slide by the steel cable, and finally the blades are synchronously flipped by the synchronous limit rod to realize the opening or closing of the louver grille. Although this solution can move all the louver blades and stack them to one side, it still has the following shortcomings in actual application:

[0003] First, since the blades of the louver grille are overlapped with each other when the louver grille is closed, when the louver grille is opened, the rear end of each blade flips downward, leaving an open gap between the blades. This causes accumulated water, dust, leaves and other debris on the blades to fall directly off, causing the sunroom to become dirty instantly, affecting the environmental sanitation in the sunroom, and there is also a safety hazard of being hit by debris.

[0004] Secondly, since the blades of the louver grille are overlapped with each other when closed, and a waterproof rubber pad is provided at the overlapping part of one of the blades, although it can improve the waterproof performance, it is difficult to ensure whether there is any debris affecting the sealing of the overlap during each closing process. When there is debris at the overlap and encounters typhoons and heavy rains, the overlap is very prone to water leakage, and its reliability in preventing water leakage is still relatively poor.

[0005] Therefore, it is very necessary to redesign a stackable and foldable louver blade structure that prevents water leakage and debris from falling, so as to better meet the application needs of the shading equipment industry. Utility Model Content

[0006] The utility model aims to solve the above-mentioned problems and shortcomings and to provide a stackable and foldable louver blade structure. In the process of unfolding and stacking and folding, each blade body of the louver blade structure has a leak-proof and waterproof adhesive strip to cover the hinge seam formed between each adjacent blade body, thereby ensuring that there is no water leakage between each adjacent blade body and having high anti-leakage performance; and it is well ensured that the louver structure has good stacking and folding performance and occupies a smaller area after folding, so that the sunroom can obtain a larger and more open transparent area after the louver is folded; and the leak-proof and waterproof adhesive strip can also intercept the accumulated water, dust, leaves and other debris on the blade body at the hinge between each adjacent blade body to prevent the debris from falling, thereby ensuring that the environmental sanitation in the sunroom is not affected and preventing people from being hit by debris, thereby having high safety.

[0007] The technical solution of the utility model is implemented as follows: a stackable foldable louver blade structure includes a plurality of blade bodies, wherein each two adjacent blade bodies are hinged to each other, and a leak-proof and waterproof rubber strip arranged along the length direction is also connected to the hinge between each two adjacent blade bodies, so that the hinge seam formed between each two adjacent blade bodies can be covered by the leak-proof and waterproof rubber strip.

[0008] Preferably, each blade body is provided with a rubber strip embedding groove, and the leak-proof and water-stopping rubber strip is provided with a rubber strip embedding portion matching the rubber strip embedding groove, and the rubber strip embedding portion is embedded in the rubber strip embedding groove.

[0009] Preferably, the utility model further comprises a hinge, and every two adjacent blade bodies are hinged together through the hinge.

[0010] Preferably, a hinge blade sinking groove is further provided on the blade body, and the fixed end of the hinge hinge is embedded in the hinge blade sinking groove.

[0011] Preferably, the blade body includes two first profile parts and a second profile part connecting the two first profile parts.

[0012] Preferably, the two first profile parts are respectively provided with a profile embedding groove, and the second profile part is provided with a profile embedding portion matching the profile embedding groove, and the profile embedding portion is embedded in the profile embedding groove.

[0013] Preferably, a radial cross-sectional height of the second profile portion is lower than a radial cross-sectional height of the first profile portion, so as to form a water collecting and drainage groove between the second profile portion and the two first profile portions.

[0014] Preferably, a water guiding slope is respectively provided on one side of the two first profile portions facing the second profile portion.

[0015] The beneficial effects of the utility model are as follows: since the blade bodies of the utility model are connected together by a hinged manner, the blade bodies can be stacked and folded, and the gaps between the blade bodies can be greatly reduced. Moreover, by connecting the leakproof and waterproof adhesive strips arranged along the length direction at the hinge between each two adjacent blade bodies, the leakproof and waterproof adhesive strips can be used to block the hinge seams formed between each two adjacent blade bodies during the unfolding, stacking and folding process. Even in the event of a typhoon or heavy rain, it can be ensured that there will be no water leakage between each two adjacent blade bodies, greatly improving its water-proof performance. At the same time, during the stacking and folding process, the leakproof and waterproof adhesive strips can also intercept the accumulated water, dust, leaves and other debris on the blade bodies at the hinge between each two adjacent blade bodies to prevent the debris from falling, thereby ensuring that the environmental sanitation in the sun room is not affected, and preventing people from being hit by debris, which is highly safe. In addition, the structural design can well ensure that the shutter structure has good stacking and folding performance and occupies a smaller area after folding, so that the sun shed can obtain a larger and more open transparent area after the shutters are folded.

[0020] like Figure 1 and Figure 2As shown, the stackable foldable shutter blade structure described in the utility model includes a plurality of blade bodies 1. In order to achieve the purpose proposed by the utility model, each adjacent two blade bodies 1 are hinged together, and the hinge between each adjacent two blade bodies 1 is also connected with a leakproof waterproof adhesive strip 2 arranged along its length direction, so that the hinge seam formed between each adjacent two blade bodies 1 is blocked by the leakproof waterproof adhesive strip 2. In the process of unfolding and stacking and folding, each blade body 1 of the utility model has a leakproof waterproof adhesive strip 2 to block the hinge seam formed between each adjacent two blade bodies 1, which can ensure that there is no water leakage between each adjacent two blade bodies 1, and the water leakage prevention performance is high; and the leakproof waterproof adhesive strip 2 can also intercept the accumulated water, dust, leaves and other debris on the blade body 1 at the hinge between each adjacent two blade bodies 1, to prevent the debris from falling, to ensure that the environmental sanitation in the sun room is not affected, and to prevent people from being hit by debris, with high safety.

[0021] In order to more easily, stably and reliably install the rubber strip embedding portion 21 and the blade body 1 together, as shown in FIG. Figure 1 As shown, each blade body 1 is provided with a rubber strip embedding groove 11 , and the leakproof and waterproof rubber strip 2 is provided with a rubber strip embedding portion 21 matching the rubber strip embedding groove 11 , and the rubber strip embedding portion 21 is embedded in the rubber strip embedding groove 11 .

[0022] In order to prevent the rubber strip embedding portion 21 and the rubber strip embedding groove 11 from being easily loosened, Figure 1 As shown, the radial cross-sections of the rubber strip embedding portion 21 and the rubber strip embedding groove 11 are both T-shaped, circular, square or triangular. Of course, they can also be heart-shaped or other shapes that can achieve the purpose of preventing loosening.

[0023] In order to make it easier for each two adjacent blade bodies 1 to be hinged together, Figure 2 As shown, the utility model further includes a hinge 3, and each two adjacent leaf bodies 1 are hinged together through the hinge 3. The hinge 3 is not only easy to implement, but also has a simple structure and occupies less space. In actual application, the hinge 3 is a hinge 3 with hinge leaves commonly used in the market.

[0024] In order to make the gap between each adjacent two blade bodies 1 smaller after the blade bodies 1 are stacked and folded together, as shown in FIG. Figure 2 and Figure 3As shown, the blade body 1 is also provided with a hinge blade sinking groove 12, and the fixed end of the hinge hinge 3 is embedded in the hinge blade sinking groove 12. Specifically, the fixed end of the hinge hinge 3 is a hinge blade. In this way, the distance that the hinge hinge 3 protrudes from the blade body 1 can be reduced, thereby further reducing the volume of each blade body 1 after being stacked and folded together, and occupying less space.

[0025] In order to make the blade body 1 easier to process and produce, Figure 3 As shown, the blade body 1 includes two first profile parts 13 and a second profile part 14 connecting the two first profile parts 13. Since the blade profile with a large width needs to be produced by extrusion processing with a larger diameter column, not only there is a lot of waste, but also the mold is large and the cost is high. At the same time, the blade profile with a large width is not easy to cool and shape quickly, and there is a situation that it is easy to collapse and deform, and the yield rate is low. Through such a split structural design, it can be divided into several blade profiles with small widths for processing and production. In this way, not only there is less waste, the mold is also small, and it can be quickly cooled and shaped, and the yield rate is high. In actual application, the first profile part 13 is made of aluminum profile, and the second profile part 14 can be made of aluminum profile or other materials. In this way, the material cost and weight of the blade body 1 can be reduced according to actual needs.

[0026] In order to more easily, stably and reliably install the second profile part 14 and the first profile part 13 together, as shown in FIG. Figure 3 As shown, the two first profile parts 13 are respectively provided with profile embedding grooves 131 , and the second profile part 14 is provided with a profile embedding portion 141 matching the profile embedding groove 131 , and the profile embedding portion 141 is embedded in the profile embedding groove 131 .

[0027] In order to prevent the profile embedding portion 141 and the profile embedding groove 131 from being easily loosened, Figure 3 As shown, the radial cross-sections of the profile embedding portion 141 and the profile embedding groove 131 are both T-shaped, circular, square or triangular. Of course, they can also be heart-shaped or other shaped structures, as long as they can achieve the purpose of preventing loosening.

[0028] In order to make the blade body 1 have the function of collecting and draining water, Figure 3 As shown, the radial cross-sectional height of the second profile part 14 is lower than the radial cross-sectional height of the first profile part 13, so as to form a water collection and drainage groove between the second profile part 14 and the two first profile parts 13. In this way, rainwater can be drained away in time when it rains.

[0029] In order to guide rainwater into the drainage trough, Figure 3As shown, the two first profile parts 13 are respectively provided with water guiding slopes 132 on one side facing the second profile part 14. This is more conducive to collecting water and draining rainwater.

[0030] like Figure 4 As shown, in actual application, rainwater in the water collection and drainage trough flows to the sun room troughs on both sides of the water collection and drainage trough for drainage.

[0031] When the blade body 1 adopts a split structural design, a leak-proof waterproof strip 2 can also be provided thereon to shield the joint between the first profile part 13 and the second profile part 14. This can facilitate the processing and production of the blade body 1 while ensuring the water-proof performance.

[0032] Through the above-mentioned structural design, when the louver blade structure is applied to the sun room shelf, it is only necessary to set a pulley on each blade body 1, so that each blade body 1 can slide on the slide rail on the sun room shelf through the pulley to realize the movement and unfolding and the movement and stacking and folding of the louver blade structure.
