[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention is now described with reference to the accompanying drawings.

[0035] The present invention provides a pneumatic curtain wall structure, which has the advantages of firm, reliable and stable structure, durable pneumatic curtain wall and the like.

[0036] To this end, the present invention proposes a wind-driven curtain wall structure with a swing axis, such as Figure 1 , Figure 2 and Figure 3 As shown, the pneumatic curtain wall structure comprises:

[0037] A first vertical bracket 1, and a second vertical bracket 2 parallel to the first vertical bracket 1; the first vertical bracket 1 and the second vertical bracket 2 are both hollow pipes, such as aluminum profiles or plastic steel, used to support the entire structure, with a light structure and convenient installation and drilling;

[0038] The transverse bracket 3 is a plurality of transverse brackets parallel to each other, and the two ends of the transverse bracket are respectively connected to the first vertical bracket 1 and the second vertical bracket 2; the transverse bracket 3 is a hollow pipe, such as an aluminum profile or plastic steel, and the two ends are fixed to the first vertical bracket and the second vertical bracket by bolts, and the transverse bracket is used to carry the wind blade; thus, the installation is convenient and the structure is firm;

[0039] A plurality of pneumatic blade connection devices 4 are arranged on the transverse bracket, and a limiting device 6 is arranged on the pneumatic blade connection device 4, and the limiting device 6 includes a transverse limiting portion and a circumferential limiting portion;

[0040] Wind blade 5, such as Figure 4 , Figure 5 and Figure 6 As shown, it is in sheet form and can be made of plastic, aluminum or aluminum alloy, or steel sheet. There are multiple of them and they are connected to the pneumatic sheet connecting device through a limit device. The multiple pneumatic sheets are located in a plane when stationary and swing when the wind blows to form a pneumatic curtain wall. Multiple pneumatic sheets are arranged on each horizontal bracket and are independent of each other.

[0041] The first sleeve 50, such as Figure 4 , Figure 5 and Figure 6 As shown, it is connected to the top of the wind blade 5, and the axis of the first sleeve 50 and the wind blade 5 are located in the same plane;

[0042] The swing shaft 55 is arranged in the first sleeve 50 and fixedly connected to the first sleeve 50; the lateral limit portion includes a second sleeve 60; both ends of the swing shaft 55 are rotatably arranged in the second sleeve 60, the outer diameter of the first sleeve 50 is larger than the inner diameter of the second sleeve 60, and both ends of the swing shaft 55 extend out of the first sleeve 50 and enter into the shaft hole 601 of the second sleeve 60. The wind-actuated blade 5 is connected to the second sleeve 60 through the swing shaft 55, so that it can swing with the wind, and has small resistance, small wear, and is durable;

[0043] The first sleeve 50 is limited between two adjacent second sleeves 60, so that the second sleeve 60 forms an axial limit, i.e., a lateral limit, on the first sleeve 50, and the first sleeve 50 is fixedly connected to the swing shaft 55, so that the first sleeve 50 is fixedly connected to the wind blade 5, so that the second sleeve 60 forms an axial limit, i.e., a lateral limit, on the wind blade 5. Through the axial limit between the sleeves, the wind blade 5 is subjected to uniform axial force, has strong wind resistance, and can move with the wind when the wind blows, but is not easily twisted or damaged.

[0044] The first shaft sleeve 50, the second shaft sleeve 60 and the swing shaft 55 are all located inside the tubular protective cover and are protected by the tubular protective cover. Therefore, the service life and rotation of the pneumatic blade can be effectively guaranteed.

[0045] Furthermore, if Figure 7 and Figure 8 As shown, the circumferential limit portion is connected to the lower part of the second sleeve 60; the circumferential limit portion includes a clamping device that forms a fixed angle and clamps on both sides of the wind blade 5. The clamping device can be formed by two clamping edges and a clamping surface that form an angle.

[0046] Furthermore, if Figure 7 and Figure 8 As shown, the clamping device includes a first clamping surface 8 and a second clamping surface 14 clamped on both sides of the pneumatic blade, and the axis of the first sleeve 50 is parallel to the first clamping surface 8 and the second clamping surface 14. The clamping device is composed of, for example, a first clamping plate 61 and a second clamping plate 63 that form an angle. The first clamping surface 8 is the inner side surface of the first clamping plate 61, and the second clamping surface 14 is the inner side surface of the second clamping plate 63. In this way, the clamping area or limiting area for the swing of the pneumatic blade 5 is larger, and the pneumatic blade 5 is not easy to twist and damage. The width of the lateral limiting portion, i.e., the second sleeve 60, is equal to the width of the circumferential limiting portion, i.e., the two clamping plates. In this way, it is convenient to manufacture the limiting device 6 in an integrated manner. For example, the limiting device 6 is made of plastic steel or aluminum alloy or steel through an integrated mold.

[0047] A hollow triangular or fan-shaped space is formed between the first clamping surface 8 and the second clamping surface 14; the triangular or fan-shaped space limits the wind blade to swing only within the angle of the fan in the swinging state, so that the wind blade can only swing circumferentially within a certain angle, which increases stability. The wind blade is vertically downward under the action of gravity when it is stationary, ensuring the beauty of the wind-driven curtain wall; the entire curtain wall can be kept flat and the structure is stable and durable in a windless state. The angle between the first clamping surface 8 and the second clamping surface 14 is an acute angle, which can be between 30 degrees and 60 degrees, for example, 30 degrees, 45 degrees, and 60 degrees, so as to control the swing of the wind blade 5 within the range of gentle swinging, and prevent the wind blade 5 from swinging too much when the wind is too strong, thereby damaging the wind blade 5.

[0048] Preferably, Figure 1 As shown, both ends of the transverse bracket 3 are connected to the first vertical bracket 1 and the second vertical bracket 2 by bolts respectively; both ends of multiple transverse brackets are connected to the first vertical bracket and the second vertical bracket by bolts respectively, and the bolt connection facilitates the disassembly of the device, and facilitates the construction and replacement of the device.

[0049] Preferably, Figure 2 As shown, the cross-section of the transverse bracket 3 is rectangular, for example, a regular quadrilateral hollow tube, and grooves 7 are provided at the upper and lower ends of the transverse bracket; the length direction of the transverse bracket is parallel to the axial direction of the swing shaft 55, and the wind-actuated blade connecting device 4 is engaged with the groove 7 so that the wind-actuated blade connecting device 4 can be stably fixed on the transverse bracket.

[0050] Preferably, Figure 2 As shown, the transverse bracket is clamped with a plurality of wind blade connection devices 4 through grooves 7; the clamping connection mode facilitates the removal of the wind blade connection devices and the connection is stable. In addition, on the basis of the clamping connection between the wind blade connection devices 4 and the transverse bracket 3, the wind blade connection devices 4 can also be fastened to the transverse bracket 3 by bolts to increase stability.

[0051] Preferably, Figure 3 As shown, the pneumatic blade connection device 4 includes a fixed portion connected to the transverse bracket 3 and an extended portion extending outward from the transverse bracket, and the pneumatic blade is connected to the extended portion; that is, the pneumatic blade connection device is "L"-shaped, leaving sufficient swing space for the pneumatic blade 5. There is a clamping table 11 on the fixed portion, and a limiting device 6 on the extended portion. The extended portion has an outer end and an inner end, the inner end of the extended portion is connected to the fixed portion, the pneumatic blade is connected to the outer end of the extended portion, and the limiting device is arranged at the outer end of the extended portion. Such a structure is convenient for connection with the transverse bracket and for swinging and limiting the pneumatic blade 5.

[0052] Preferably, Figure 3 and Figure 4 As shown, the fixed part includes a vertical beam 10 and a clamping platform 11 arranged at the upper and lower ends of the vertical beam, the extending part includes a horizontal beam 9, and the limiting device 6 is arranged on the horizontal beam; the clamping platform 11 and the horizontal beam 9 are respectively located on the left and right sides of the vertical beam 10; the grooves 7 at the upper and lower ends of the horizontal bracket match the clamping platforms 11 at the upper and lower ends of the vertical beam; the pneumatic blade connecting device connects the pneumatic blade and the horizontal bracket, and multiple pneumatic blade connecting devices are connected to multiple horizontal brackets to form a pneumatic curtain wall.

[0053] Preferably, Figure 5 , Figure 6 and Figure 7As shown, the wind blade 5 includes a connecting portion 51 connected to the first sleeve 50 and a rectangular blade 53 located below the connecting portion and connected to the connecting portion. The connecting portion 51 is located between two adjacent second sleeves 60, or in other words, the connecting portion 51 is equal to the length of the first sleeve 50, so that the wind blade 5 can have room to swing. The rectangular blade 53 is located below the second sleeve 60, and the axial length of the first sleeve 50 is less than the length of the rectangular blade 53, and the length of the rectangular blade 53 is greater than the length of the connecting portion 51. In this way, the second sleeve 60 does not affect the rotation of the connecting portion 51 or the swing shaft of the wind blade 5, and can limit the rectangular blade 53, resulting in a simple result and good swinging effect and limiting effect.

[0054] Preferably, the transverse supports are provided in one or more rows, and a plurality of the pneumatic blade connecting devices are provided on each row of transverse supports; each pneumatic blade is connected to two adjacent pneumatic blade connecting devices arranged transversely, and the plurality of pneumatic blades are spaced apart from each other and arranged independently, and form a matrix; or it may be a triangular curtain wall, a quadrilateral curtain wall, etc.

In the case of wind, the pneumatic blade 5 can only swing circumferentially within a certain angle. Due to the limiting effect of the first clamping surface on the left side, the pneumatic blade 5 can swing from the vertical direction to a maximum of Figure 3 The dotted line position of the left wind moving piece 5 in the figure is limited by the second clamping surface on the right side and can swing to Figure 3 The dotted line position of the right side air moving piece 5 in the figure. And when limiting, the limiting of the air moving piece 5 by the first clamping surface 8 is surface contact, and the inner wall of the first clamping surface 8 and the outer side surface of the air moving piece 5 overlap each other, so that the stability of the limiting is achieved.
