[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The fixing frame is provided with a connection component and a groove. The connecting sheet metal is fixed to the wall with bolts. The curtain wall panel is placed close to the fixing frame, and the support plate is placed on top of the fixing frame. This can save some effort. The installation rod is aligned with the installation groove, and the curtain wall panel is pressed to press the installation rod into the installation groove. When the installation rod is completely inserted into the installation groove, the first spring pushes the triangular block into the locking groove through the sliding cross block. The installation rod is locked by inserting the triangular block into the locking groove. The curtain wall panel is fixed by locking the installation rod, and the installation rod enters the installation groove. When the curtain wall panel is installed, the fixing block enters the groove at the same time, the extrusion block is inserted into the containing groove, the extrusion block squeezes the two locking block inclined surfaces, the locking block is squeezed out of the sliding groove by the extrusion block, and inserted into the locking groove.

(2) Before installing the curtain wall panel, open the flip plate and inject polyurethane foam into the placement groove. As the installation rod enters the installation groove, the installation groove squeezes the flip plate to rotate into the placement groove, squeezing the polyurethane foam in the placement groove out of the placement groove, so that the polyurethane foam fills the installation groove or seeps out of the installation groove. When the polyurethane foam expands and solidifies, the polyurethane foam remaining in the placement groove lifts the flip plate, so that the flip plate is stuck in the recessed groove inside the installation groove. The solidified polyurethane foam cooperates with the flip plate and the recessed groove to improve the stability of the curtain wall panel and the polyurethane After the ester foam glue expands and solidifies, it can fill the gap between the installation rod and the installation groove to prevent the curtain wall panel from shaking due to processing accuracy problems during subsequent use. After fixing the curtain wall panel on one side of the fixed frame, use a tool corresponding to the non-circular groove on the rotating disk to rotate the rotating disk. The rotating disk drives the first threaded rod to rotate, and the first threaded rod drives the second threaded rod to rotate through the rotating plate. The second threaded rod and the first threaded rod enter the threaded groove and drive the connecting vertical plate to move toward the vertical rod direction of the fixed frame. The connecting vertical plate drives the rod to insert into the slot and the through hole to lock the installation rod inside the installation groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The curtain wall panel 2 is provided with a placement slot 24 , which is arranged on the short cross bar. A flip plate 241 is rotatably connected in the placement slot 24 , and the rotation axis of the flip plate 241 is arranged in the placement slot 24 at one side close to the locking assembly 23 .

[0026] The working principle of the present invention is as follows: when installing, firstly, the connecting sheet metal 13 is fixed to the wall by bolts, the curtain wall panel 2 is placed close to the fixing frame 1, and the support plate 21 is placed on the fixing frame 1. When installing the curtain wall panel 2, the fixing frame 1 has a supporting effect on the curtain wall panel 2 through the support plate 21. When installing the curtain wall panel 2, some effort can be saved. The installation rod 22 is aligned with the installation groove 11, the curtain wall panel 2 is pressed, and the installation rod 22 is pressed into the installation groove 11. The installation rod 22 squeezes the triangular block 125 obliquely. The triangular block 125 is inserted into the sliding cavity 122. When the installation rod 22 is completely inserted into the installation groove 11, the installation rod 22 no longer squeezes the triangular block 125. The first spring 123 pushes the sliding horizontal block 124, thereby pushing the triangular block 125 out of the sliding cavity 122 through the sliding horizontal block 124. The triangular block 125 is inserted into the locking groove 221. The installation rod 22 is locked by inserting the triangular block 125 into the locking groove 221, and the curtain wall panel 2 is fixed by locking the installation rod 22. When the installation rod 22 enters the installation groove 11, the fixing block 231 enters the groove 15 at the same time, and the extrusion block 151 is inserted into the containing groove 232 as 131 enters, and the extrusion block 151 squeezes the inclined surfaces of the two locking blocks 235, so that the distance between the two locking blocks 235 increases, and the locking block 235 is squeezed out of the sliding groove 233 by the extrusion block 151 and inserted into the locking groove 152. The locking component 23 is fixed in the groove 15 by the extrusion force during installation, and the locking component 23 and the groove 15 cooperate with the installation rod 22 and the connecting component 12 to fix the curtain wall panel 2 on the outside of the fixing frame 1 first. Due to the setting of the support plate 21, the physical strength of the construction workers can be saved when installing the curtain wall panel 2, and the support plate 21 is attached to the fixing frame 1, which can assist the construction workers in calibrating the position of the curtain wall panel 2 and improve the installation time. Before installing the curtain wall panel 2, the flip plate 241 is opened and polyurethane foam is injected into the placement groove 24. The flip plate 241 is supported by the polyurethane foam and cannot be rotated into the placement groove 24. As the installation plug rod 22 enters the installation groove 11, the installation groove 11 squeezes the flip plate 241 to rotate into the placement groove 24. At the same time, the polyurethane foam in the placement groove 24 is squeezed out from the placement groove 24, so that the polyurethane foam fills the installation groove 11 or seeps out from the installation groove 11. When the polyurethane foam expands and solidifies, the polyurethane foam remaining in the placement groove 24 lifts the flip plate 241, so that the flip plate 241 is stuck in the recessed groove inside the installation groove 11. The solidified polyurethane foam cooperates with the flip plate 241 and the recessed groove to improve the stability of the curtain wall panel 2. After the polyurethane foam expands and solidifies, it can fill the gap between the installation plug rod 22 and the installation groove 11 to prevent the curtain wall panel 2 from shaking due to processing accuracy problems during subsequent use. After the curtain wall panel 2 is fixed on one side of the fixed frame 1, a tool corresponding to the non-circular groove on the rotating disk 184 is used to rotate the rotating disk 184. The rotating disk 184 drives the first threaded rod 185 to rotate. The first threaded rod 185 drives the second threaded rod 188 to rotate through the rotating plate 187. The second threaded rod 188 and the first threaded rod 185 enter the threaded groove 16 and drive the connecting vertical plate 181 to move toward the vertical rod direction of the fixed frame 1. The connecting vertical plate 181 drives the insertion rod 183 to insert into the slot 17 and the through hole 222, and locks the installation insertion rod 22 inside the installation groove 11.

The protection scope of the present invention is defined by the claims.
