[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] See also Figure 1-Figure 9A curtain wall structure that is easy to install, comprising four groups of curtain wall sheets 1, four corners of the curtain wall sheets 1 are symmetrically provided with fixing holes 101, the four groups of curtain wall sheets 1 are connected by the same docking unit 2, the docking unit 2 comprises a mounting seat 21, a welding pipe 22 is arranged on the mounting seat 21, the docking unit 2 also comprises four extension plates 3 that are equidistantly distributed in a circular ring shape, a support column 31 is fixedly installed at one end of the extension plate 3 away from the welding pipe 22, and a docking column 32 is arranged at the end of the support column 31;

[0035] The support column 31 has four movable grooves 4 equidistantly distributed in a circular shape inside, and the four movable grooves 4 extend to the inside of the docking column 32, the inner side surface of the movable groove 4 is slidably connected with a movable plate 41, the inner side surface of the docking column 32 is provided with a guide groove 42, the inside of the guide groove 42 is slidably connected with a docking block 43, the docking block 43 is provided with an arc portion 44 on the side away from the support column 31, a linkage plate 45 is rotatably connected between the docking block 43 and the movable plate 41, an extension groove connected to the movable groove 4 is provided inside the support column 31, the ends of the four movable plates 41 are fixedly connected to the same connecting plate 46, and a support spring 47 is fixedly connected between the connecting plate 46 and the inner wall of the extension groove.

[0036] In this embodiment, a working cavity is opened on one side of the movable groove 4 close to the guide groove 42 , and the linkage plate 45 is arranged inside the working cavity, and the specification of the working cavity is adapted to the linkage plate 45 .

[0037] It should be noted that the working cavity is connected to the movable groove 4 and the guide groove 42 , and its size specification can meet the movement requirements of the linkage plate 45 when the movable plate 41 moves.

[0038] In this embodiment, the shape and size of the docking column 32 are compatible with the fixing hole 101, and the diameter of the support column 31 is larger than the aperture value of the fixing hole 101, so that the docking column 32 can be stably inserted into the fixing hole 101, thereby stably connecting the curtain wall piece 1, and the diameter of the support column 31 is larger than the aperture value of the fixing hole 101, so that the support column 31 can limit the movement of one side of the curtain wall piece 1, so that with the cooperation of the docking block 43, the curtain wall piece 1 can be stably fixed.

[0039] In this embodiment, the distance between the connecting block 43 and the end of the supporting column 31 is adapted to the thickness of the curtain wall sheet 1, so that after the curtain wall sheet 1 is installed, the connecting block 43 can stably squeeze the curtain wall sheet 1, making the installation stability of the curtain wall sheet 1 better.

[0040] Before installing the curtain wall sheet 1, the mounting seat 21 is welded and fixed on the preset support frame through the welding pipe 22. During installation, the operator aligns the fixing hole 101 on the suspended curtain wall sheet 1 with the docking block 43 and presses it in the direction close to the mounting seat 21. When subjected to the pressing force, the inner wall of the fixing hole 101 will contact and squeeze the circular arc portion 44 on the docking block 43. Under the guiding action of the circular arc portion 44, the docking block 43 is pushed in the inner direction of the guide groove 42, so that it can move into the guide groove 42 and enter. In this process, under the transmission action of the linkage plate 45, the docking block 43 can drive the movable plate 41 and the connecting plate 46 to move when it moves, and the connecting plate 46 will compress the support spring 47 during the movement;

[0041] When the docking block 43 completely enters the guide groove 42, the movement of the curtain wall piece 1 is no longer hindered. At this time, the fixing hole 101 on the curtain wall piece 1 can continue to move until the curtain wall piece 1 contacts the end of the support column 31. When the curtain wall piece 1 passes through the end of the docking block 43, under the action of the rebound force of the support spring 47, the docking block 43 moves in the opposite direction and resets, and contacts the surface of the curtain wall piece 1. Therefore, with the cooperation of the support column 31, the curtain wall piece 1 can be stably fixed, and the curtain wall piece 1 can also be quickly installed.

[0042] Embodiment 2:

[0043] See also Figure 3 The interior of the mounting seat 21 is equidistantly provided with four sets of wheel grooves 5 in a circular shape, the inner side of the wheel groove 5 is rotatably connected with a winding wheel 51, a connecting groove 52 is provided between the wheel groove 5 and the extension groove, a pulling rope 53 is wound on the outside of the winding wheel 51, and a hand wheel 54 corresponding to the winding wheel 51 is rotatably connected to the outside of the mounting seat 21.

[0044] In this embodiment, one end of the pulling rope 53 is rolled up on the outer surface of the winding wheel 51 , and the other end of the pulling rope 53 passes through the connecting groove 52 and is fixedly connected to the connecting plate 46 . The hand wheel 54 is coaxially fixedly connected to the winding wheel 51 .

[0045] During subsequent disassembly, the operator can manually rotate the reel 51 indoors to reel in one end of the pulling rope 53, so that under the guiding action of the connecting groove 52, the other end of the pulling rope 53 can pull the connecting plate 46 to move it and drive the movable plate 41 to move. Under the transmission action of the linkage plate 45, the docking block 43 can be pulled to slide along the inner wall of the guide groove 42 and enter the interior of the guide groove 42, so that it no longer restricts the movement of the curtain wall piece 1. At this time, the curtain wall piece 1 can be adsorbed and suspended by the adsorption suspension equipment to achieve its disassembly, thereby making the subsequent disassembly of the curtain wall piece 1 safer.

[0046] Embodiment three:

[0047] See also Figure 5-Figure 9 The docking column 32 includes a fixed portion 321 and a movable portion 322. The fixed portion 321 is provided with a connecting groove 6 extending to the inside of the support column 31. The end of the movable portion 322 is fixedly connected to the connecting column 61. The inner wall of the guide groove 42 is provided with a limiting guide groove 62. The shape of the limiting guide groove 62 is T-shaped. The surface of the docking block 43 is fixedly connected with a limiting guide block 63. The shape and size of the limiting guide block 63 are adapted to the limiting guide groove 62. The limiting guide block 63 is slidably connected to the inner side surface of the limiting guide groove 62.

[0048] In this embodiment, straight grooves 64 are symmetrically provided on both sides of the inner wall of the connecting groove 6, and a first arc block 65 is fixedly connected inside the straight groove 64. Moving grooves are symmetrically provided on both sides inside the connecting column 61, and a second arc block 66 is slidably connected inside the moving groove. A connecting spring 67 is fixedly connected between the second arc block 66 and the inner wall of the moving groove. An embedding groove is provided at the end of the movable part 322, and a pulling block 68 is slidably connected inside the embedding groove. A wiring groove is provided between the embedding groove and the moving groove, and one end of a traction rope 69 is fixedly connected to the surface of the second arc block 66, and the other end of the traction rope 69 passes through the wiring groove and is fixedly connected to the pulling block 68, and a finger groove 610 is provided on the surface of the pulling block 68.

[0049] In this embodiment, the first arc block 65 and the second arc block 66 are both provided with straight facing ends away from the arc side. When the straight facing end of the second arc block 66 abuts against the surface of the straight groove 64 close to the pull block 68, the distance between the movable part 322 close to the fixed part 321 and the end face of the support column 31 is greater than the thickness of the curtain wall sheet 1. When the connecting column 61 moves to abut against the inner wall of the connecting groove 6, the second arc block 66 moves to the straight facing end and abuts against the straight facing end of the first arc block 65.

[0050] It should be added that the shape of the connecting column 61 is a rectangular strip, and the shape and specification of the connecting groove 6 are adapted to the connecting column 61, so that the connecting column 61 cannot rotate during the sliding process along the inner wall of the connecting groove 6, thereby ensuring the stability of the movable part 322 during operation, and at the same time effectively preventing the movable part 322 from rotating during operation, causing the linkage plate 45 to be damaged by the rotational force;

[0051] Furthermore, under the supporting force of the connecting spring 67 , the friction resistance of the docking block 43 when sliding along the inner wall of the guide groove 42 is much smaller than the friction resistance of the connecting plate 46 when moving under the supporting force of the supporting spring 47 .

[0052] It should be noted that, before the curtain wall piece 1 is installed, the movable portion 322 and the fixed portion 321 are spaced apart so that the distance between the movable portion 322 and the support column 31 is greater than the thickness of the curtain wall piece 1. Therefore, during the installation process, when the curtain wall piece 1 abuts against the end faces of the support column 31, the docking block 43 and the curtain wall piece 1 are in a separated state. Therefore, the curtain wall piece 1 will not hinder the resetting of the docking block 43.

[0053] After the curtain wall sheet 1 is installed to abut against the end surface of the supporting column 31, the operator directly manually presses the movable portion 322 to move it in the direction of the fixed portion 321. During this process, the movable portion 322 moves to drive the connecting column 61 to move along the inner wall of the connecting groove 6 and drive the second arc block 66 to move. During the movement of the second arc block 66, it will contact the arc portion on the first arc block 65, so that the second arc block 66 moves toward the inside of the moving groove and compresses the connecting spring 67, so that the second arc block 66 enters the inside of the moving groove, so that the second arc block 66 can pass through the end of the first arc block 65, and after passing, under the action of the rebound force of the connecting spring 67, the second arc block 66 moves in the opposite direction to reset, and makes the straight end on the second arc block 66 abut against the straight end on the first arc block 65, so that the reverse movement of the second arc block 66 is blocked;

[0054] When the movable portion 322 moves, it drives the docking block 43 to move. When it moves to the point where the straight end on the first arc block 65 abuts against the straight end on the second arc block 66, the docking block 43 moves to abut against the surface of the curtain wall piece 1, thereby cooperating with the support column 31 to stably fix the curtain wall piece 1.

[0055] When the position of the docking block 43 needs to be adjusted after the curtain wall panel 1 needs to be disassembled, the operator pulls the pulling block 68 outward through the finger groove 610 to pull the traction rope 69, so that the other end of the traction rope 69 pulls the second arc block 66 to move into the movable groove. At this time, the reverse movement of the second arc block 66 is no longer restricted. At this time, the operator can pull the movable part 322 in the reverse direction to drive the docking block 43 to move in the reverse direction and reset.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
