Several elastic rods 6-10 are evenly installed on the ball head rod 6-2 in an umbrella-shaped structure, and all the elastic rods 6-10 extend outwardly and contact the inner surface of the outer wall 3. The elastic rod 6-10 can effectively buffer the deflection of the outer wall 3 in any direction, absorb external wind force, and enable the outer wall 3 to reset. The end of the elastic rod 6-10 that contacts the outer wall 3 is spherical and is equipped with a sliding ball 6-11. The sliding ball 6-11 is tightly attached to the outer wall 3. By setting the sliding ball 6-11, when the outer wall 3 is deflected, the sliding ball 6-11 can slide on the outer wall 3, further exerting the role of the elastic rod 6-10.

[0028] See attached Figure 1 and attached Figure 2In order to enhance the spacing adjustment effect between the inner wall 2 and the outer wall 3, the adjustment device 5 is optimized, and the flexible connecting member can be selected as a connecting rope 5-2.

It can also cooperate with the stabilizing device 6 to further stabilize the outer wall 3 and prevent the outer wall 3 from falling off.

[0029] See attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 6 , an annular plate 6-9 is arranged on the ball head rod 6-2, and a plurality of groups of elastic rods 6-10 are evenly arranged between the annular plate 6-9 and the outer wall 3, one end of the elastic rod 6-10 can be installed on the outer edge of the annular plate 6-9, or can be directly connected to the ball head rod 6-2, and the connection is located above the annular plate 6-9. A limiting rod 6-12 is also arranged at the end of the stable base 6-1 away from the inner wall 2, and one end of the limiting rod 6-12 is installed on one side of the opening 6-8, and a limiting hole 6-13 matching with the limiting rod 6-12 is arranged on the annular plate 6-9, and the limiting rod 6-12 is arranged in the limiting hole 6-13. By setting the limiting rod 6-12 and the limiting hole 6-13, the movement process of the ball head rod 6-2 in the cavity 6-5 can be further stabilized. The other end of the limiting rod 6-12 is provided with a limiting component 6-14, and the cross section of the limiting component 6-14 is larger than the cross section of the limiting hole 6-13. By providing the limiting component 6-14, it can cooperate with the baffle 6-6 and the limiting ball head rod 6-2 to further prevent the ball head rod 6-2 from escaping from the cavity 6-5. In this embodiment, the limiting component 6-14 is a limiting block, and those skilled in the art can also choose a limiting ball as the limiting component 6-14.

[0030] See attached Figure 3 and attached Figure 7The outer surface of the ball head 6-3 is provided with an arc-shaped first slide groove 6-31, and the inner surface of the ball seat 6-4 is provided with a second slide groove 6-41 matched with the first slide groove 6-31. The slideway composed of the first slide groove 6-31 and the second slide groove 6-41 is provided with a ball 6-15. By providing the first slide groove 6-31 and the second slide groove 6-41, the ball 6-15 can slide in the slideway composed of the first slide groove 6-31 and the second slide groove 6-41. The cross-sections of the first slide groove 6-31 and the second slide groove 6-41 are both semicircular, and the plane where the first slide groove 6-31 is located is perpendicular to the plane where the inner wall 2 is located, and the plane where the second slide groove 6-41 is located is perpendicular to the plane where the outer wall 3 is located. By setting the cross-sections of the first slide groove 6-31 and the second slide groove 6-41 to be semicircular, the ball 6-15 can slide smoothly in the slide; by setting the plane where the first slide groove 6-31 is located to be perpendicular to the plane where the inner wall 2 is located, and the plane where the second slide groove 6-41 is located to be perpendicular to the plane where the outer wall 3 is located, under the action of the ball 6-15, the ball seat 6-4 and the outer wall 3 can be deflected with the ball head 6-3 as the center, preventing the ball seat 6-4 and the outer wall 3 from rotating with the ball head rod 6-2 as the rotation axis.

[0031] See attached Figure 5, the inner wall 2 is installed with mounting bolts 9. When in use, the inner wall 2 is installed on the wall by the mounting bolts 9, so that the curtain wall units 1 are arranged in sequence. The adjusting bases 5-11 installed on the four sides of the inner wall 2 are divided into four groups, including two groups in the horizontal direction and two groups in the vertical direction. That is, the wire take-up 5-1 on one curtain wall unit is divided into two groups of wire take-ups 5-1 in the horizontal direction and two groups of wire take-ups 5-1 in the vertical direction. The wire take-ups 5-1 in the same horizontal direction in the curtain wall unit 1 can be sequentially connected through the horizontal connecting shaft 7, and the wire take-ups 5-1 in the same vertical direction in the curtain wall unit 1 can be sequentially connected through the vertical connecting shaft 8. The wire pulley of the wire take-up 5-1 in the horizontal direction is set at one end of the adjusting base 5-1 close to the outer wall 3, and the wire pulley of the wire take-up 5-1 in the vertical direction is set at the end of the adjusting base 5-1 close to the outer wall 3. One end of the inner wall 2 is close to the horizontal connecting shaft 7, so that the horizontal connecting shaft 7 and the vertical connecting shaft 8 are misaligned to avoid contact with each other; one end of the horizontal connecting shaft 7 and the vertical connecting shaft 8 are respectively connected to the output end of the driving motor, and the driving motor drives the horizontal connecting shaft 7 and the vertical connecting shaft 8 to rotate respectively, and then can drive the wire take-up device 5-1 in the same horizontal direction or vertical direction to work, and the wire take-up device 5-1 in the horizontal direction and the vertical direction of the inner wall 2 can work at the same time or separately, so as to actively adjust the posture of the outer wall 3 to adapt to various wind environments; when a group of wire wheels tighten the connecting When the rope 5-2 is pulled, the outer wall 3 will deflect toward the direction of the wire wheel. At this time, the elastic rod 6-10 on this side is deformed by force to support the outer wall 3. When the four sets of wire wheels tighten the connecting rope 5-2 together, the outer wall 3 will translate as a whole close to the inner wall 2. At this time, the ball head rod 6-2 compresses the spring 6-7. When the external wind force hits the outer wall 3, the outer wall 3 will deflect with the ball head 6-3 as the center in accordance with the wind force, thereby reducing the impact of the wind force on the outer wall 3. The elastic rod 6-10 on the deflected side is deformed by force to buffer the wind force and enhance the supporting effect on the outer wall 3. When the wind force is transmitted to the ball head rod 6-2 When the wind changes direction, the outer wall 3 will deflect with the ball head 6-3 as the center in accordance with the wind force, always follow the wind direction, reduce impact, and effectively extend the service life of the curtain wall unit 1; when the wind weakens or disappears, the outer wall 3 will be reset under the action of the elastic component 6-7 and the elastic rod 6-10; the present invention can not only effectively bear and unload external wind loads according to the wind direction, but also strengthen the connection reliability between the inner wall 2 and the outer wall 3, and improve the stability of the curtain wall.

[0032] The curtain wall unit of the first embodiment can be used alone or spliced ​​to form a curtain wall. Each of the curtain wall units 1 is connected by a connecting shaft, and the connecting shaft includes several horizontal connecting shafts 7 and several vertical connecting shafts 8. The curtain wall units 1 in the same row are connected by the horizontal connecting shaft 7, and the curtain wall units 1 in the same column are connected by the vertical connecting shaft 8. The horizontal connecting shaft 7 and the vertical connecting shaft 8 respectively penetrate all the adjustment bases 5-11 in the same horizontal direction and the same vertical direction, and are connected to the wire take-up device 5-1 in the adjustment base 5-11. One end of all the horizontal connecting shafts 7 and all the vertical connecting shafts 8 is connected to a driving motor, and the driving motor drives the horizontal connecting shaft 7 and the vertical connecting shaft 8 to rotate, thereby driving the wire take-up device 5-1 to tighten or loosen the connecting rope 5-2. The other ends of all the horizontal connecting shafts 7 and all the vertical connecting shafts 8 are located in the adjustment base 5-11 of the first curtain wall unit 1 in the same row / column. All the horizontal connecting shafts 7 can be connected to the same driving motor or to different driving motors. The connection schemes of all the longitudinal connecting shafts 8 and the drive motor can be the same as that of the transverse connecting shaft 7 .

[0033] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
