[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figures 1 to 6 As shown, the pneumatic blade connection mechanism of the first embodiment of the utility model is applied to pneumatic louver curtain walls, and specifically includes a connection member 10, a pneumatic blade 20, a rotating assembly 30 and a locking element 40.

[0050] The connecting member 10 is provided with a first connecting hole 11; the pneumatic blade 20 is provided with a second connecting hole 21; during assembly, the rotating assembly 30 is assembled and connected in the first connecting hole 11 and the second connecting hole 21, thereby realizing the assembly connection between the connecting member 10 and the pneumatic blade 20; the locking element 40 is assembled and connected to the rotating assembly 30 to prevent the pneumatic blade 20 from falling off. The connecting member 10 and the pneumatic blade 20 can swing with the rotating assembly 30 as the axis to realize the function of swinging with the wind.

[0051] In this embodiment, the connecting member 10 is provided with symmetrically distributed connecting arms 12, the first connecting hole 11 is provided on the connecting arm 12, the connecting arm 12 provides an assembly space, and the connecting member 10 and the connecting arm 12 form a C-shape, and the connecting member 10 is formed by stamping or bending, which reduces the difficulty of production; specifically, the corners of the lower end of the connecting arm 12 are provided with abutting edges 13, which are used to limit the rotation angle of the wind blade 20. Both sides of the wind blade 20 are provided with side edges 22 arranged perpendicularly thereto, and the second connecting hole 21 is provided on the side edges 22. A weight-bearing member 23 is provided on the side edges 22, so that the wind blade 20 remains vertical in a windless state.

[0052] In this embodiment, if Figure 5 to Figure 6 As shown, the connecting member is a connecting shaft 31, and the locking element 40 is a buckle 41. Specifically, the connecting shaft 31 includes a convex ring 311, a first shaft portion 312 provided on one side of the convex ring 311, and a second shaft portion 313 provided on the other side of the convex ring 311, and a groove 314 is provided on the outer wall of the second shaft portion 313 away from the convex ring 311.

[0053] During installation, if Figure 4 As shown, the first shaft portion 312 is connected to the inner side of the first connection hole 11, specifically by riveting or screwing, so that the connection shaft 31 is integrally connected to the connection member 10. The second shaft portion 313 is connected to the second connection hole 21, and a gap is left between the second shaft portion 313 and the second connection hole 21 to ensure that the wind blade 20 can swing around the second shaft portion 313. A clamping block 411 is provided on the inner side of the buckle 41, and the clamping block 411 is clamped in the groove 314, against the side 22, to prevent the wind blade 20 from being separated from the connection shaft 31.

[0054] In this embodiment, if Figures 1 to 4 As shown, the rotating assembly 30 also includes a first sleeve 32 made of non-metallic material. The first sleeve 32 is sleeved on the outer side of the second shaft portion 313 and inserted into the inner side of the second connecting hole 21; the first sleeve 32 is located between the second shaft portion 313 and the second connecting hole 21, reducing the friction between the pneumatic blade 20 and the connecting shaft 31, thereby playing a role in noise reduction.

[0055] Compared with the existing pneumatic blade connection mechanism, the three components of the rotating assembly 30, the pneumatic blade 20 and the connecting member 10 are connected to each other through the snap connection of the buckle 41 and the connecting shaft 31, which is easy to install; and the working noise is reduced by the first sleeve 32.

[0056] See also Figures 7 to 9 FIG. 1 is a pneumatic blade connection mechanism of the second embodiment of the present invention. The pneumatic blade connection mechanism of the second embodiment is different from the first embodiment in that the connection assembly and the locking element 40 are provided. In this embodiment, the rotating assembly 30 is a screw 33 and the locking element 40 is a nut 42.

[0057] During installation, the screw 33 passes through the second connecting hole 21, the nut 42 and the first connecting hole 11 in sequence; the nut 42 and the screw 33 are screwed together through threads to clamp the air blade 20; a rotation gap is left between the tail end of the screw 33 and the first connecting hole 11 to ensure that the air blade 20 swings around the screw 33 as the axis.

[0058] In this embodiment, if Fig. 9 As shown, a non-metallic gasket 34 is sleeved on the outer side of the screw 33, and the gasket 34 is arranged between the nut 42 and the connecting member 10. At the same time, a second sleeve 35 made of non-metallic material is sleeved on the outer side of the screw 33, and the second sleeve 35 is inserted into the inner side of the first connecting hole 11 to reduce friction and play a role in noise reduction.

[0059] In this embodiment, if Fig. 9 As shown, the gasket 34 and the second sleeve 35 are an integrated structure.

[0060] See also Figures 10 to 12 As shown, the pneumatic blade connection mechanism of the third embodiment of the utility model is similar to the pneumatic blade connection mechanism of the second embodiment, and the difference is that the gasket 34 and the second sleeve 35 adopt a separate structure.

[0061] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
