TECHNICAL FIELD

The present application discloses a louver blade, a louver blade assembly, and a pergola.

BACKGROUND

The louver pergola is a sunshade tool that can achieve light transmission and shading by controlling the flipping of the louvers. Compared with the traditional pergola, it has won the favor of more people because of its flexibility in use. However, the current louver pergolas on the market are relatively poor in waterproof performance due to gaps between the louver blades. In order to solve the problem of waterproofing, CN112609913A discloses a louver blade assembly, comprising a louver blade assembly and a frame, the louver blade assembly comprises a number of louver blades arranged in sequence, a linkage bar for linking a plurality of the louver blades, and a louver quick-installation piece for cooperating with the frame; The louver blade comprises a louver blade body, a drainage hanging bucket located on the side of the louver blade body, and a waterproof strip arranged on the louver blade body. By adding a waterproof strip, the waterproof partition between adjacent louver blades can be realized and the collision between the louvers after they are closed can be avoided. However, the waterproof strip is prone to aging after long-term exposure to the sun and rain, which makes later maintenance difficult, and repeated disassembly and assembly will also damage the appearance of the product.

FIG. 1 is a schematic structural diagram of an embodiment of a louver blade according to the present application. The louver blade is mainly used in external louvers, pergolas, and venetian blinds. The louver blade comprises a louver blade body 1, wherein a first matching part 11 and a second matching part 12 are respectively provided on two long sides of the louver blade body 1. When in use, a plurality of louver blades are used together. When the plurality of louver blades are closely matched with each other to realize the shielding effect, the plurality of louver blade bodies 1 are horizontally unfolded and cooperate with each other. At this time, a louver blade body 1 cooperates with a second mating part 12 of an adjacent louver blade body 1 through its first matching part 11, i.e. louver blade body 1 cooperates with a second mating part 12 of an adjacent louver blade body 1 through its first matching part 11, so that an overlapping sealing area is formed between two adjacent louver blade bodies 1. Therefore, when the plurality of louver blade bodies cooperate to achieve shading, there is no gap between two adjacent louver blades, and water or sunlight cannot pass between two adjacent louver blades, and the waterproof and sunshade effect is good, and the vision is smooth and beautiful.
In the embodiment, the first matching part 11 is an undercut structure, the second matching part 12 is adapted to the structure of the first matching part (11), the first matching part 11, the second matching part 12 are integrally formed with the louver blade body 1. The second matching part 12 can be a vertical plate structure, or a plate structure with an inverted L-shaped cross section, or a P-shaped or barb-shaped cross-sectional structure. In other embodiments, a sealing strip may also be arranged on the side of the second matching part 12 close to the first matching part 11.
Further, the louver blade body 1 can be a flat plate structure. In this embodiment, the louver blade body 1 is a plate structure with a middle part protruding upwards, and a cross section of the louver blade body 1 is in the shape of an arch bridge. This facilitates the drainage of rainwater and reduces the accumulation of rainwater.
Referring to FIG. 2 -FIG. 6 , in an application scenario, a plurality of louver blades are assembled on the beam frame 2 to form a louver blade assembly. Both short sides of each louver blade body 1 on the louver blade assembly are respectively connected with an end plate 2. A rotating shaft 21 is arranged on the end plate 2, and a plurality of the louver blade bodies 1 are respectively hinged on the beam frame 3 through the rotating shaft 21. A hinge hole is formed above the end plate 2. Transmission rods 4 are provided on both sides of the louver blade bodies 1, a fixed shaft is arranged on the transmission rod 4, and the end plate 2 is hinged to the fixed shaft of the transmission rod 4 through a hinge hole. The plurality of louver blade bodies 1 are also hinged to the two transmission rods 4 through the end plates 2 on both sides respectively, and one of the rotating shafts 21 is connected with a driving mechanism, and the driving mechanism drives one of the louver blades to rotate, so that the transmission rod 4 drives each of the louver blade bodies 1 to rotate synchronously.
In order to install the louver blades on the beam frame 2, the two beams 32 connected to the rotating shaft 21 are provided with inverted Z-shaped grooves for installing the rotating shaft 21. The inverted Z-shaped groove is arranged on the upper end of the inner beam 32. The installation of the louver blades is done by putting the rotating shafts 21 on both sides of the louver blades into the inverted Z-shaped grooves. The inverted Z-shaped groove can limit the movement of the rotating shaft 21, thereby preventing the louver blades from falling off due to the sliding of the rotating shaft 21.
The driving mechanism can be a manual handpiece, a hand wheel, or an electric motor. The driving mechanism can manually or electrically drive the louver blade body 1 to turn over, so as to control the closing or opening of the louver blade assembly, which can be set according to needs, without further limitation.
In detail, the end plate 2 has an L-shaped structure, and the two sides of the end plate 2 are connected to the first matching part 11 and the second matching part 12 by screws, and the end plate 2 is provided with drain holes 22 and drain ports 23. The rainwater on the louver blade body 1 can be drained away through the drain holes 22 and the drain ports 23.
In addition, the beam frame 3 is formed by connecting four beams end to end. In order to ensure the stability of the beam structure and good load-bearing performance, the beam includes an outer beam 31 and an inner beam 32 arranged in parallel, and the outer beam 31 and the inner beam 32 are connected by a horizontal connecting beam 33. In this embodiment, the outer beam 31 and the inner beam 32 are vertical plates, and the horizontal connecting beam 33 is a horizontal plate. A first drainage groove 34 is positioned between the outer beam 31 and the inner beam 32. The rainwater falling on the beam frame 3 can be collected into the first drainage groove 32, and then drained away through the first drainage groove 34, which can reduce rainwater splashing. One side of the inner beam 32 is provided with a second drainage groove 36, and the notch of the second drainage groove 36 is arranged between the louver blade body 1 and the beam, that is, the second drainage groove 36 is arranged below0 the end plate 2. The rainwater discharged through the drain hole 22 and the drain port 23 of the end plate 2 will flow to the second drainage groove 36 and be diverted through the second drainage groove 36, which can also reduce rainwater splashing.
Referring to FIGS. 7-10 , in an application scenario, the louver blade assembly is prepared as a pergola, and the louver blade assembly of the pergola is connected with four posts 5 for supporting the louver blade assembly. The middle part of the post 5 is provided with a drainage channel, and the drainage channel communicates with the first drainage groove 32 and the second drainage groove 36. Rainwater can be diverted to the drainage channel through the first drainage groove 32 and the second drainage groove 36, and then stored or discharged through the drainage channel.
In detail, in order to facilitate assembly and disassembly, a coordination groove 51 adapted to a corner of the beam frame 3 of the louver blade assembly is formed at one end of the post 5, and a plurality of the reinforcing ribs 52 are arranged in the coordination groove 51, Two adjacent reinforcing ribs 52 can form a inlay groove. Both sides of the corners of the beam frame body 3 are provided with fillets 35. The fillet 35 is adapted to the inlay groove. The quantity of fillets 35 can be set as required. When the beam frame 3 is connected with the post 5, the fillet 35 is inserted between two reinforcing ribs 52.
In order to further improve the stability of the connection between the beam frame 3 and the post 5, the beam frame 3 and the post 5 can also be connected by locking bolts, and the locking bolts are preferably arranged in the first drainage groove 32 on one side of the outer beam 31.
In addition, the top and bottom of the post 5 are provided with a sealing plate 6, and the sealing plate 6 is connected with the post 5 by screws. The sealing plate 6 at the bottom of the post 5 can seal the bottom of the drainage channel, which is conducive to storing rainwater. When drainage is required, the sealing plate 6 at the bottom of the post 5 can be disassembled.
In summary, the present application discloses a louver blade, which comprises a louver blade body, wherein a first matching part and a second matching part are respectively provided on two long sides of the louver blade body. When a plurality of louver blade bodies are assembled on the beam frame and the louver blade assembly is fully closed, a plurality of louver blade bodies are horizontally unfolded and cooperate with each other, a louver blade body cooperates with a second mating part of an adjacent louver blade body through its first matching part, so that an overlapping sealing area is formed between two adjacent louver blade bodies, so that no gap fit can be realized, and the function of tight fit and shielding can be realized.
