[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Figure 1-2 The utility model provides an embodiment: a corner profile connection structure for a curtain wall, including a column 1 and a curtain wall panel 22. The front and rear sides of the column 1 are rotatably connected to a first rotating shaft 2, and the outer wall of the first rotating shaft 2 is fixedly connected to a connecting column 3. The connecting column 3 is fixed by the first rotating shaft 2, so that the connecting column 3 can rotate inside the two sides of the column 1. The outer wall of the connecting column 3 is fixedly connected to a mounting frame 4, and the mounting frame 4 is used to install the curtain wall panel 22. A cavity is opened through the upper and lower parts of the column 1, and a synchronization mechanism is provided inside the cavity. The synchronization mechanism works internally by setting the cavity. One side of the column 1 is fixedly connected to a shell 5, and the shell 5 is used to support the first threaded rod 6. A slide groove 23 is opened on the front and back sides of the shell 5. The inside of the shell 5 is rotatably connected to the first threaded rod 6, and the outer wall of the first threaded rod 6 is threadedly connected to the moving block 7. The outer walls of the moving block 7 are fixedly connected to connecting blocks 8 on both sides. When the moving block 7 drives the connecting block 8 to move in the shell 5, the connecting block 8 moves in the slide groove 23, which can not only guide the connecting block 8 when sliding, but also slide the connecting block 8 in the slide groove 23 when the moving block 7 moves, limiting the sliding distance. One side of the connecting block 8 is fixedly connected to the first bracket 24, and the inside of the first bracket 24 is rotatably connected to the connecting plate 9.

[0039] Secondly, one end of the connecting plate 9 is rotatably connected to the second bracket 10, the first bracket 24 is used to connect one end of the connecting plate 9, and the second connecting bracket is used to connect the other end of the connecting plate 9. One side of the second bracket 10 is fixedly connected to the fixing plate 11, and then the direction of the moving block 7 is driven to move according to the rotation of the first threaded rod 6 in the shell 5, so that the direction in which the moving block 7 moves is caused to allow the first connecting bracket to drive one end of the connecting plate 9 to move, so that the other end of the connecting plate 9 pushes the curtain wall panels 22 on both sides of the column 1 to expand to both sides or retract to both sides of the shell 5. One end of the curtain wall panel 22 is connected to the inside of the mounting frame 4, so that one end of the curtain wall panel 22 is fixed, and the fixing plate 11 is connected to one side of the curtain wall panel 22 by a nut, and is connected to the curtain wall panel 22 by a nut, so that the second bracket 10 is fixed to one side of the curtain wall panel 22.

[0040] Reference Figure 1-2 When the fixing plate 11 is not connected to the curtain wall panel 22, the operator accidentally touches one of the curtain wall panels 22 when installing the curtain wall panel 22. At this time, the angles of the curtain wall panels 22 on both sides of the column 1 are inconsistent, which requires manual adjustment of one of them when installing the fixing plate 11, greatly reducing the construction efficiency. At this time, through the synchronization mechanism, the synchronization mechanism includes a first gear 12 and a second gear 14. The front and rear sides of the cavity are evenly rotated and connected with two second shafts 13. The first gear 12 is fixedly connected to the outer wall of the second shaft 13, and the two second gears 14 are meshed with each other. The first gear 12 is fixedly connected to both ends of the first rotating shaft 2. The first gear 12 and the second gear 14 mesh with each other. When the first gear 12 drives one of the second gears 14 to rotate on the second rotating shaft 13, one of the second gears 14 transmits the transmission to the other second gear 14 to drive the other second gear 14 to rotate the first gear 12 on the first rotating shaft 2 on the other side of the column 1, thereby causing the first gear 12 on one side of the column 1 to rotate counterclockwise. Through the transmission of the two second gears 14, the second gear 14 on the other side of the column 1 rotates clockwise. A clamping plate 15 is slidably connected to one side of the interior of the installation frame 4. The clamping plate 15 is used to clamp the curtain wall panel 22 when it is installed in the installation frame 4. A second threaded rod 17 is rotatably connected to the center of one side of the splint 15, and the second threaded rod 17 is threadedly connected to the inside of the mounting frame 4. The upper and lower parts of one side of the splint 15 are fixedly connected with a sliding rod 16, and the sliding rod 16 is slidably connected to the inside of the mounting frame 4. When the second threaded rod 17 is rotated, the thread on the second threaded rod 17 pushes the splint 15 to move to the other side of the inside of the mounting frame 4, thereby clamping and fastening one end of the curtain wall panel 22 placed in the mounting frame 4, and the sliding rod 16 is fixedly connected to the upper and lower parts of the splint 15 to position the position of the splint 15 when it moves.

[0041] Reference Figure 2-3The upper surface of the column 1 is fixedly connected to a block 18, and the lower surface of the column 1 is fixedly connected to a slot plate 20. The block 18 is interlocked with the slot provided in the slot plate 20. The block 18 is in the shape of a dovetail slider, and the slot provided on the upper surface of the slot plate 20 is a dovetail groove. The block 18 corresponds to the slot plate 20. Due to the special shape of the dovetail slider and the dovetail groove, the block 18 has transverse and longitudinal connection rigidity, which can provide a high load-bearing capacity. This matching method can withstand large vertical and transverse loads. When the block 18 on one three-dimensional column is interlocked with the slot plate 20 on another column 1, the overall length of the column 1 is increased. One side of the block 18 is fixedly connected to a limit plate 19, which is used to limit the position when it cooperates with the slot plate 20. One end of the first threaded rod 6 is fixedly connected to a handle 21, which is used to drive the first threaded rod 6 to rotate.

[0042] Working principle: When using this device, first, when the overall length of the column 1 needs to be adjusted, the block 18 on one three-dimensional column is engaged with the card slot plate 20 on the other column 1, and a limit plate 19 is fixedly connected to one side of the block 18 to limit the position when cooperating with the card slot plate 20, thereby increasing the overall length of the column 1, and the first rotating shaft 2 is rotatably connected to both sides of the column 1, and the outer wall of the first rotating shaft 2 is connected to the connecting column 3, and the installation frame 4 is installed on one side of the connecting column 3, and then one end of the curtain wall panel 22 is inserted into the installation frame 4, and then by rotating The second threaded rod 17 pushes the clamping plate 15 to move to one side of the mounting frame 4 through the rotation of the second threaded rod 17, thereby clamping the curtain wall panel 22, and then rotating one of the curtain wall panels 22. At this time, the first gears 12 at both ends of the first rotating shaft 2 drive one of the second gears 14 to rotate on the second rotating shaft 13. Because the two second gears 14 are engaged with each other, one of the second gears 14 rotates to drive the other second gear 14, and then rotates the first gear 12 on the first rotating shaft 2 on the other side of the column 1, so that the first gear 12 on one side of the column 1 To rotate counterclockwise, the second gear 14 on the other side of the column 1 is driven by the two second gears 14, so that the second gear 14 on the other side of the column 1 rotates clockwise so that the two curtain wall panels 22 are opened and closed synchronously. Then, the connecting blocks 8 are fixedly connected on both sides of the moving block 7 in the shell 5 to connect the first bracket 24. One end of the connecting plate 9 is connected to the inside of the first bracket 24, and the other end of the connecting plate 9 is connected to the second bracket 10, and a fixing plate 11 is fixedly connected to one side of the second bracket 10. Then, the fixing plate 11 is fixed to one side of the curtain wall panel 22 by bolts. When it is necessary to adjust the opening and closing angle between the two curtain wall panels 22 When the moving block 7 moves to the left, the first connecting frame drives one end of the connecting plate 9 to move, so that the other end of the connecting plate 9 pushes the curtain wall panels 22 on both sides of the column 1 to expand to both sides, so that the angle of the corner position of the curtain wall panels 22 is expanded. When the moving block 7 moves to the right, the curtain wall panels 22 on both sides of the column 1 are retracted toward both sides of the shell 5 through the connecting plate 9, so that the angle of the corner position of the curtain wall panels 22 is reduced, so as to adjust the angle between the two curtain wall panels 22 to fit.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
