[0035] 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.

[0036] Reference Figures 1-5 An embodiment of this utility model is provided: a high-density ventilation PVC louver, including a frame 1, angle adjustment components are provided on the inner sides of both ends of the frame 1, a drive component is provided on the inner side of the end of the frame 1, a limit component is provided on the inner sides of both ends of the frame 1, and two mounting components are provided on the outer sides of both ends of the frame 1.

[0037] The angle adjustment assembly includes a connecting frame 13, which is rotatably connected to the inner side of the end of frame 1. Multiple connecting rods 17 are fixedly connected to the inner side of the connecting frame 13, and each connecting rod 17 has a connecting block 8 fixedly connected to its end. When the connecting frame 13 rotates, it drives the multiple connecting rods 17 fixedly connected to its inner side to rotate, thereby causing the connecting block 8 connected to the end of the connecting rod 17 and the blade 6 fixed inside the connecting block 8 to rotate together, thus adjusting the angle of the blade 6 and controlling the ventilation volume and direction. The drive assembly includes a control wheel 5, which is rotatably connected to the inner side of the end of frame 1. A semicircular block 16 is fixedly connected to the end of the control wheel 5, and another semicircular block 16 is rotatably connected to its end. Connecting rods 15 are rotatably connected to both sides of the end of the two semicircular blocks 16, and connecting blocks 14 are fixedly connected to the other ends of the two connecting rods 15. The connecting blocks 14 are fixedly connected to the outer side of the middle of one of the connecting frames 13. Rotating the control wheel 5 drives the semicircular block 16 fixed at its end to rotate. When the semicircular block 16 rotates, the connecting rod 15, which is rotatably connected to both ends, pulls the connecting block 14. Since the connecting block 14 is fixed to the outer side of the middle of one of the connecting frames 13, the connecting frame 13 will rotate about the rotational connection point with the frame 1.

[0038] Reference Figure 2 , Figure 4 and Figure 7The limiting component includes a connecting rod 18, which is rotatably connected to the inner side of the connecting frame 13 and the inner end of the connecting rod 17. A slider 12 is fixedly connected to the side of the connecting rod 18. A groove 19 is provided on the inner side of the end of the frame 1, and the slider 12 is slidably connected to the inner side of the groove 19. When the connecting frame 13 rotates, the connecting rod 18 rotates with the connecting frame 13. Because the slider 12 is fixedly connected to the side of the connecting rod 18 and is slidably connected in the groove 19 on the inner side of the end of the frame 1, the slider 12 slides in the groove 19, limiting the movement trajectory of the connecting rod 18, thereby limiting the rotation angle of the connecting frame 13 and ensuring that the blade 6 can only rotate within a specified angle range.

[0039] Reference Figure 1 , Figure 2 and Figure 6 The installation assembly includes a slot block 2, which is fixedly connected to the outside of the frame 1. A snap-fit ​​block 3 is slidably connected to the inside of the slot block 2, and two fixing bolts 4 are installed on the inner side of the end of the snap-fit ​​block 3. During installation, the snap-fit ​​block 3 is aligned with the slot block 2, and then the snap-fit ​​block 3 is inserted into the inside of the slot block 2, allowing it to slide within the slot block 2. Once it reaches the appropriate position, the snap-fit ​​block 3 is fixed in the installation position using the two fixing bolts 4 installed on the inner side of the end of the snap-fit ​​block 3, thereby fixing the entire louver frame 1 in place.

[0040] Reference Figure 1 , Figure 2 and Figure 7 The frame 1 has a drainage channel 9 on its inner bottom side, and multiple drainage holes 10 on the inner bottom side of the drainage channel 9. Multiple connecting blocks 8 are fixedly connected to blades 6 on their inner sides, and the ends of the blades 6 are interlocked. Because the ends of the blades 6 are interlocked, rainwater will collect in the drainage channel 9 on the inner bottom side of the frame 1, and then drain out of the louvers through the multiple drainage holes 10 on the inner bottom side of the drainage channel 9, preventing rainwater from accumulating inside the louvers. Multiple drainage grooves 7 are provided on the outer sides of the multiple blades 6. When rainwater falls on the blades 6, it will flow down along the multiple drainage grooves 7 on the outer side of the blades 6. Limiting plates 11 and 20 are fixedly connected to both ends of the frame 1, with two blades 6 respectively located on the sides of the limiting plates 11 and 20. During rotation, the position of the blades 6 is restricted, preventing them from wobbling and ensuring the stability of the connection between the blades 6. This also improves the sealing of the louvers when closed, preventing dust, insects, etc., from entering the room.

[0041] Working principle: First, rotating the control wheel 5 drives the semicircular block 16 at the end to rotate. The semicircular block 16 drives the connecting block 14 to move through the connecting rod 15. Since the connecting block 14 is fixed on the outer side of the middle of one of the connecting frames 13, the connecting frame 13 will rotate around the rotation connection point with the frame 1. The connecting rod 17 and the connecting block 8 on the inner side of the connecting frame 13 will also rotate, thereby driving the blade 6 fixedly connected to the inner side of the connecting block 8 to rotate, realizing the adjustment of the blade 6 angle, thereby controlling the ventilation volume and ventilation direction.

[0042] When the connecting frame 13 rotates, the connecting rod 18 will rotate together with the connecting frame 13. The slider 12 on the side of the connecting rod 18 slides in the groove 19 opened on the inner side of the end of the frame 1. Through the cooperation of the slider 12 and the groove 19, the rotation angle of the connecting frame 13 is limited, thereby ensuring that the blade 6 rotates within the specified angle range, playing a limiting role and preventing the blade 6 from rotating excessively and affecting the normal use and structural stability of the louver.

[0043] When rainwater enters the louvers, the multiple drainage channels 7 on the outer side of the blades 6 can guide the rainwater to the drainage channel 9 on the inner side of the bottom of the frame 1, and then drain the rainwater through the multiple drainage holes 10 on the inner side of the bottom of the drainage channel 9, so as to avoid the rainwater from accumulating inside the louvers, prevent water accumulation from damaging the louvers, and extend their service life.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
