Sliding cavities are respectively formed at both ends of the connecting short rod. A sliding cross block is slidably connected in the sliding cavity. One end of the sliding cross block is fixedly connected with a triangular block, and a first spring is arranged between the other end of the sliding cross block and the inside of the sliding cavity.

[0008] Preferably, locking grooves are formed on both sides inside the groove, and an extrusion block is fixedly connected to one side inside the groove. The two locking grooves are arranged oppositely.

[0009] Preferably, the fixed frame is composed of two vertical rods and two horizontal rods. Thread grooves are formed on both of the two vertical rods of the fixed frame. Insertion slots are formed on both the upper sides of the vertical rods of the fixed frame. The four connecting short rods are respectively arranged in the two vertical rods and the horizontal rods. Thread grooves are also formed on the connecting short rods inside the vertical rods. The thread grooves correspond to the second threaded rod and the first threaded rod, and the inserting rods correspond to the insertion slots.

[0010] Preferably, three support plates are fixedly connected to the side of the curtain wall board facing the fixed frame. Four groups of installation inserting rods are arranged on one side of the curtain wall board, and two groups of locking components are arranged on one side of the installation inserting rods.

[0011] Preferably, the installation inserting rod is composed of a short cross bar and a short vertical rod. The installation inserting rod is integrally L-shaped. Two locking grooves are formed on the installation inserting rod. One of the locking grooves is formed at one end of the short vertical rod, and the other locking groove is formed at one end of the short cross bar. A through hole is formed on the installation inserting rod and is arranged on the short vertical rod.

[0012] Preferably, the locking assembly includes a fixed block fixedly connected to the installation insertion rod. Two groups of the fixed blocks are respectively fixedly connected to the short vertical rod and the short horizontal rod on the installation insertion rod.

The sliding grooves are connected to the receiving groove in a penetrating manner. A connecting groove is formed on one side inside the sliding groove. Locking blocks are respectively slidably connected in the two sliding grooves. A connecting plate is fixedly connected to one side of each locking block. A second spring is arranged between the two connecting plates.

[0013] Preferably, a placement groove is provided on the curtain wall panel. The placement groove is arranged on the short horizontal rod. A flipping plate is rotatably connected in the placement groove. The rotation axis of the flipping plate is arranged on one side of the placement groove close to the locking assembly.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0015] (1) A connecting component and a groove are arranged in the fixed frame. Bolts are used to fix the connecting sheet metal to the wall. The curtain wall panel is close to the fixed frame. The support plate is placed on the upper part of the fixed frame, which can save some effort. The installation insertion rod is aligned with the installation groove. Press the curtain wall panel to insert the installation insertion rod into the installation groove. When the installation insertion rod completely enters the installation groove, the first spring pushes the triangular block into the locking groove through the sliding cross block. The installation insertion rod is locked by the triangular block inserted into the locking groove. When the installation insertion rod enters the installation groove, the fixed block also enters the groove at the same time. The extrusion block is inserted into the receiving groove. The extrusion block extrudes the inclined surfaces of the two locking blocks. The locking blocks are extruded out of the sliding groove by the extrusion block and inserted into the locking groove. Through the extrusion force during installation, the locking assembly is fixed in the groove. The locking assembly and the groove cooperate with the installation insertion rod and the connecting component to fix the curtain wall panel on the outer side of the fixed frame first. Due to the setting of the support plate, the physical strength of the construction workers can be saved during the installation of the curtain wall panel. Moreover, the support plate fits on the fixed frame, which can assist the construction workers to calibrate the position of the curtain wall panel and improve the installation time;

[0016] (2)Before installing the curtain wall panel, lift the flipping plate and inject polyurethane foam into the placement groove. As the installation rod enters the installation groove, the installation groove squeezes the flipping 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 oozes out of the installation groove. When the polyurethane foam expands and cures, the polyurethane foam remaining in the placement groove pushes up the flipping plate, causing the flipping plate to be stuck in the concave groove inside the installation groove. Through the cooperation of the cured polyurethane foam with the flipping plate and the concave groove, the stability of the curtain wall panel is improved. Moreover, after the polyurethane foam expands and cures, it can fill the gap between the installation rod and the installation groove, preventing 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 fixing 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. 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 towards the vertical rod of the fixing frame. The connecting vertical plate drives the insertion rod to insert into the insertion slot and the through hole, locking the installation rod inside the installation groove.

The overall shape of the installation plug rod 22 is L-shaped. Two locking grooves 221 are formed on the installation plug rod 22. One of the locking grooves 221 is formed at one end of the short vertical bar, and the other locking groove 221 is formed at one end of the short cross bar. A through hole 222 is formed on the installation plug rod 22. The through hole 222 corresponds to the slot 17. The through hole 222 is arranged on the short vertical bar.

[0037] The locking component 23 includes a fixed block 231 fixedly connected to the installation plug rod 22. The fixed block 231 corresponds to the groove 15. Two groups of fixed blocks 231 are respectively fixedly connected to the short vertical bar and the short cross bar on the installation plug rod 22. A receiving groove 232 is formed on one side of the fixed block 231 facing the fixed frame 1. Sliding grooves 233 are formed on both sides of the fixed block 231. The sliding grooves 233 are connected to the receiving groove 232 in a through manner. A connecting groove 234 is formed on one side inside the sliding groove 233. Locking blocks 235 are respectively slidably connected in the two sliding grooves 233. Both ends of the locking block 235 are provided with inclined surfaces. The top view of the sliding groove 233 is a parallelogram. A connecting plate 236 is fixedly connected to one side of the locking block 235. A second spring 237 is arranged between the two connecting plates 236.

[0038] A placing groove 24 is formed on the curtain wall panel 2. The placing groove 24 is arranged on the short cross bar. A turning plate 241 is rotatably connected in the placing groove 24. The rotation axis of the turning plate 241 is arranged on one side of the placing groove 24 close to the locking component 23.

[0039] The working principle of the present invention: During installation, first fix the connecting sheet metal 13 to the wall through bolts, bring the curtain wall panel 2 close to the fixed frame 1, and make the support plate 21 rest on the upper part of the fixed frame 1. When installing the curtain wall panel 2, the fixed frame 1 has a supporting effect on the curtain wall panel 2 through the support plate 21, and part of the effort can be saved when installing the curtain wall panel 2. Align the installation plug rod 22 with the installation groove 11, press the curtain wall panel 2, and press the installation plug rod 22 into the installation groove 11. The installation plug rod 22 squeezes the inclined surface of the triangular block 125, so that the triangular block 125 enters the sliding cavity 122. When the installation plug rod 22 completely enters the installation groove 11, the installation plug rod 22 no longer squeezes the triangular block 125. The first spring 123 pushes the sliding cross block 124, and then through the sliding cross block 124, the triangular block 125 is pushed out of the sliding cavity 122. The triangular block 125 is inserted into the locking groove 221. The installation plug 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 plug rod 22;

[0040] When the installation plug rod 22 enters the installation groove 11, the fixing block 231 simultaneously enters the groove 15. As the extrusion block 151 enters with the 131, it inserts into the receiving groove 232. The extrusion block 151 extrudes the inclined surfaces of the two locking blocks 235, increasing the distance between the two locking blocks 235. The locking blocks 235 are extruded by the extrusion block 151 out of the sliding groove 233 and inserted into the locking groove 152. Through the extrusion force during installation, the locking component 23 is fixed in the groove 15. The locking component 23 and the groove 15 cooperate with the installation plug rod 22 and the connecting component 12 to first fix the curtain wall panel 2 on the outside of the fixing frame 1. Due to the setting of the support plate 21, when installing the curtain wall panel 2, it can save the physical strength of the construction workers. Moreover, the support plate 21 fits on 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;

[0041] Before installing the curtain wall panel 2, lift the flipping plate 241 and inject polyurethane foam into the placing groove 24. The flipping plate 241 is supported by the polyurethane foam and cannot be turned into the placing groove 24. As the installation plug rod 22 enters the installation groove 11, the installation groove 11 squeezes the flipping plate 241 to rotate into the placing groove 24. At the same time, the polyurethane foam in the placing groove 24 is extruded from the placing groove 24, so that the polyurethane foam fills the installation groove 11 or oozes out from the installation groove 11. When the polyurethane foam expands and cures, the polyurethane foam remaining in the placing groove 24 pushes up the flipping plate 241, making the flipping plate 241 stuck in the recessed groove inside the installation groove 11. Through the cooperation of the cured polyurethane foam, the flipping plate 241 and the recessed groove, the stability of the curtain wall panel 2 is improved. And after the polyurethane foam expands and cures, it can fill the gap between the installation plug rod 22 and the installation groove 11, preventing the curtain wall panel 2 from shaking due to processing accuracy problems during subsequent use;

[0042] After fixing the curtain wall panel 2 on one side of the fixing frame 1, use a tool corresponding to the non-circular groove on the rotating disk 184 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 towards the vertical rod of the fixing frame 1. The connecting vertical plate 181 drives the plug rod 183 to insert into the slot 17 and the through hole 222, locking the installation plug rod 22 inside the installation groove 11.

[0043] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
