Secondly, the present application features a simple structure, and convenient and safe operations. A fastening bolt is used to connect a positioning insertion plate located outside the cross beam, and the positioning insertion plate only needs to be inserted into a corresponding assembly slide rail, allowing for relative position limiting of the cross beam and the upright column. Then, the fastening bolt is tightened to drive the positioning insertion plate to elastically deform to be secured in the assembly slide rail, thus fixing the cross beam to the upright column.

Thirdly, the present application achieves firm connection between the assembly crank and the louver blade through the fitting between an insertion post and an insertion hole and fitting between a limiting slot and a snap-fitted protrusion. Compared with the prior art, the present application provides convenient assembly and disassembly, which is time-saving and labor-saving, ensuring stable connection.

Lastly, in the present application, a water baffle is used to divide a water collecting slot into two chambers, with a seam located in one of the chambers. The water baffle ensures that water in the seam-free chamber does not flow into the chamber with the seam. A water guide plate above the water leakage cavity guides water to a side of the water baffle away from the water leakage cavity, preventing rainwater flowing down from the louver blade above the water leakage cavity from entering the water leakage cavity. This effectively prevents water in the water collecting slot from leaking through the seam, thereby preventing water leakage in the middle of the frame body of the louver canopy.

An upper end of the assembly crank 18 is provided with an insertion post 19 and a limiting slot 20. The louver blade 1 is provided with an insertion hole 21 for the insertion post 19 to be inserted into and fit within, and a snap-fitted protrusion 22 clamped in the limiting slot 20. A lower end of the assembly crank 18 is provided with a transmissive fitting hole 23 in transmissive fitting with the drive assembly.

As shown in FIGS. 8-11, the present application achieves firm connection between the assembly crank 18 and the louver blade 1 through the fitting between an insertion post 19 and an insertion hole 21 and fitting between a limiting slot 20 and a snap-fitted protrusion 22. Compared with the prior art, the present application provides convenient assembly and disassembly, which is time-saving and labor-saving, ensuring stable connection.

To further improve the connection firmness between the louver blade 1 and the assembly crank 18, the insertion post 19 is disposed on a side wall surface of an upper end of the louver blade 1, and the limiting slot 20 is provided on a top surface of the upper end of the louver blade 1. In other words, the fitting between the insertion post 19 and the insertion hole 21 provides lateral limiting and connection between the louver blade 1 and the assembly crank 18, while the fitting between the limiting slot 20 and the snap-fitted protrusion 22 provides vertical limiting and connection between the louver blade 1 and the assembly crank 18.

Furthermore, considering the guidance for rainwater and the lateral position of the insertion hole 21, a top surface of a rear portion of the louver blade 1 bends downwards to form a water receiving groove 24. The insertion hole 21 is provided on a side wall of the water receiving groove 24, a bottom surface of an end of the water receiving groove 24 is provided with a drainage hole 25, and the corresponding cross beam directly located below the drainage hole 25 is provided with a water collecting slot 11 for collecting rainwater.

Meanwhile, the specific structure of the drive assembly is as follows: As shown in FIGS. 10-13, the drive assembly includes a transmission shaft tube 27 that is rotatably connected to the frame body, the transmission shaft tube 27 is provided with a transmission crank 28, the transmission crank 28 is hinged with a transmission rod 30 in a transmissive manner via a connecting rod 29, and the assembly cranks 18 are each hinged with the transmission rod 30 via a transmissive fitting hole 23.

To limit the louver blade 1 in the closed state, the transmission crank 28 includes a connecting sleeve that sleeves the transmission shaft tube 27 and a connection rod with one end disposed on the connecting sleeve, and the other end of the connection rod is connected to the connecting rod 29. During rotation of the transmission shaft tube 27, the connecting rod 29 contacts the connecting sleeve to prevent the transmission shaft tube 27 from continuously rotating in a same direction, as shown in FIGS. 11 and 12.

Further, a lower end of a side wall of each of the horizontal support beams 2 close to the louver blade 1 is provided with a flow guide plate 10. A water collecting slot 11 is formed between each of the flow guide plates 10 and the corresponding horizontal support beam 2, and a seam 31 is formed between two flow guide plates 10 of the same cross beam. The water collecting slots 11 are each provided with a water baffle 32 for separating the water collecting slots 11. Two water baffles 32 of the same cross beam are respectively located on two sides of the corresponding seam 31, with a water leakage cavity 33 formed between the two water baffles 32. A water guide plate 34 that guides water to a side of the water baffle 32 away from the water leakage cavity 33 is provided above the water leakage cavity 33.

As shown in FIGS. 14-20, in the present application, a water baffle 32 is used to divide a water collecting slot 11 into two chambers, with a seam 31 located in one of the chambers. The water baffle 32 ensures that water in the chamber without the seam 31 does not flow into the chamber with the seam 31. A water guide plate 34 above the water leakage cavity 33 guides water to a side of the water baffle 32 away from the water leakage cavity 33, preventing rainwater flowing down from the louver blade 1 above the water leakage cavity 33 from entering the water leakage cavity 33. This effectively prevents water in the water collecting slot 11 from leaking through the seam 31, thereby preventing water leakage in the middle of the frame body of the louver canopy.

To prevent the water guide plate 34 from shifting and falling, as shown in FIGS. 16, 17, and 20, an insertion block plate 35 is disposed below the water guide plate 34, and the insertion block plate 35 is inserted in the water leakage cavity 33.

To facilitate processing, reduce assembly steps, and ensure the connection strength between the insertion block plate 35 and the water guide plate 34, as shown in FIGS. 16, 17, and 20, the insertion block plate 35 and the water guide plate 34 form an integral structure, a T-shaped structure.

To facilitate the insertion of the insertion block plate 35 into the water leakage cavity 7, as shown in FIGS. 16 and 17, two side walls of a lower end of the insertion block plate 35 close to the water baffle 32 are both inclined surfaces, and the two inclined surfaces are both inclined towards the middle from top to bottom.

To enable the lower surface of the water guide plate 34 to fit onto the upper surface of the water baffle 32 and prevent water from entering the space between the water guide plate 34 and the water baffle 32, the height of the insertion block plate 35 is lower than the height of the water baffle 32.
