[0023] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0024] Figure 1-Figure 5 It is the best embodiment of the utility model, and the following Figure 1-Figure 5 The utility model is further described.

[0025] like Figure 1-Figure 5 As shown, a connection assembly for curtain wall installation includes a keel frame 1 and two splicing blocks 2. The keel frame 1 is fixedly installed on the outer wall of the building by bolts or welding. Two splicing holes are opened on one side of the keel frame 1, and sliding openings are opened on both sides of the two splicing blocks 2. A fixing mechanism is slidably installed in the sliding opening. The two splicing blocks 2 are fixedly installed in the two splicing holes by the fixing mechanism, and the same curtain wall panel body 3 is fixedly installed on one side of the two splicing blocks 2.

[0026] The fixing mechanism includes a fixing block 6. The splicing block 2 is hollow. The fixing blocks 6 are symmetrically and slidably installed on both sides of the splicing block 2. The fixing grooves are symmetrically arranged on both sides of the splicing hole. The fixing blocks 6 can extend into the fixing grooves on the corresponding sides. A connecting plate 5 is rotatably installed on one side of the two fixing blocks 6. A lifting block 4 is arranged between the two connecting plates 5. The connecting plate 5 is rotatably connected to the lifting block 4. A threaded rod 7 is rotatably installed on the inner bottom wall of the splicing block 2. The lifting block 4 is screwed on the threaded rod 7. In the initial state, the two fixing blocks 6 are both arranged in the splicing block 2. The connecting plate 5 is gradually inclined downward in the direction close to the lifting block 4. When the threaded rod 7 rotates, the lifting block 4 can be driven to move upward or downward. When the lifting block 4 moves upward, it will drive the two connecting plates 5 to move and make the connecting plate 5 move to the horizontal. At this time, the connecting plate 5 pushes the two fixing blocks 6 to extend out of the splicing block 2 and extend into the corresponding fixing grooves. A rotating rod 8 is fixedly installed on the top of the threaded rod 7, and a limit ring 13 is fixedly installed outside the rotating rod 8. The limit ring 13 is installed at the connection between the threaded rod 7 and the rotating rod 8 to prevent the lifting block 4 from detaching from the threaded rod 7. A knob disk 9 is fixedly installed on the top of the rotating rod 8. A knob opening is opened on the upper side of the splicing block 2, and the knob disk 9 is rotatably installed in the knob opening. An installation opening is opened on the upper side of the keel frame 1, and the installation opening is connected to the splicing hole. When installing, a plum screwdriver is inserted to rotate the knob disk 9. A cross plum blossom groove is opened on the upper side of the knob disk 9. A plurality of plug-in grooves 10 are opened on the upper side of the knob disk 9. The plurality of plug-in grooves 10 are evenly spaced around the cross plum blossom groove. A sliding hole is opened on the keel frame 1, and a plug-in rod 11 is slidably installed in the sliding hole. The size of the plug-in rod 11 corresponds to the plug-in groove 10, and a limiting component is slidably installed on the inner wall of the fixed block 6.

[0027] Furthermore, the limiting assembly includes a slider 14, which is slidably installed in the fixed block 6. An avoidance opening is provided on the upper side of the fixed block 6. A push rod 15 is fixedly installed on the upper side of the slider 14. A movable groove 16 is provided on the inner top wall of the fixed groove. The movable groove 16 has a movable range, which allows the push rod 15 to move a certain distance in the movable groove 16. In this way, the push rod 15 will not be limited in motion when it is retracted. A pop-up unit is rotatably installed on the inner wall of the fixed block 6.

[0028] Furthermore, the pop-up unit includes a trigger rod 20, which is L-shaped, and one end of its vertical portion is rotatably mounted on the inner wall of the fixed block 6, and the horizontal portion extends to one side of the slider 14, and a spring 21 is arranged between the slider 14. Two V-shaped rods 19 are rotatably mounted on the inner wall of the fixed block 6 through a rotating shaft, and the two V-shaped rods 19 have the same size. The pop-up unit also includes a driving gear 18, which is fixedly mounted between the two V-shaped rods 19 and mounted on the rotating shaft. A partial gear 17 is fixedly mounted on one side of the connecting plate 5, and the partial gear 17 is coaxial with the hinge axis of the connecting plate 5 and the fixed block 6, and the partial gear 17 is meshed with the driving gear 18. In the initial state, the horizontal portion of the trigger rod 20 contacts the extrusion rod at the lower portion of the V-shaped rod 19.

[0029] When the connecting plate 5 gradually rotates to be parallel, it drives part of the gear 17 to rotate clockwise, and part of the gear 17 drives the driving gear 18 to rotate counterclockwise. The driving gear 18 drives the V-shaped rod 19 to rotate counterclockwise through the rotating shaft, so that the extrusion rod under the V-shaped rod 19 moves upward and squeezes one end of the trigger rod 20, so that the trigger rod 20 rotates. When the trigger rod 20 rotates to a horizontal position and continues to rotate upward from the horizontal position, the upper side of the V-shaped rod 19 limits and fixes the trigger rod 20, and drives the slider 14 to move upward under the tension of the spring 21. The slider 14 drives the ejector rod 15 to pop out and insert it into the movable groove 16. When the connecting plate 5 moves in the opposite direction, it drives part of the gear 17 to rotate in the opposite direction. At this time, the ejector rod 15 will not shrink immediately, but will make a small displacement in the movable groove 16. When the trigger rod 20 rotates to a horizontal position and rotates downward from the horizontal position, the ejector rod 15 will shrink immediately and contact the secondary limit fixation.

[0030] Furthermore, stabilizing rods 12 are fixedly installed on both sides of the lifting block 4, two extension openings are opened on the upper side of the splicing block 2, and two stabilizing grooves are opened on the top wall of the splicing hole. The two stabilizing rods 12 can be inserted into the stabilizing grooves through the two extension openings, so as to improve the fixing stability of the splicing block 2.

[0031] Working principle: When the device is in use, first install the keel frame 1 on the exterior wall of the building, then move the curtain wall panel body 3 with the splicing blocks 2 close to the keel frame 1, and insert the two splicing blocks 2 into the splicing holes, observe whether the knob disk 9 on the upper side of the splicing block 2 is aligned with the installation port, and then use a plum screwdriver to align with the cross plum slot on the knob disk 9 and rotate the knob disk 9, the knob disk 9 drives the rotating rod 8 to rotate, the rotating rod 8 drives the threaded rod 7 to rotate, the threaded rod 7 drives the lifting block 4 to move upward, the lifting block 4 drives the connecting plates 5 on both sides to move, so that the two connecting plates 5 gradually move to the horizontal, the two connecting plates 5 drive the corresponding fixing blocks 6 to move, so that the two fixing blocks 6 gradually extend out and enter the fixing groove for fixing, and in the process of the lifting block 4 rising, it drives the two stabilizing rods 12 to move upward, so that the two stabilizing rods 12 are inserted into the two stabilizing grooves for limit fixing.

[0032] When the connecting plate 5 gradually rotates to be parallel, the partial gear 17 is driven to rotate clockwise, and the partial gear 17 drives the driving gear 18 to rotate counterclockwise. The driving gear 18 drives the V-shaped rod 19 to rotate counterclockwise through the rotating shaft, so that the extrusion rod under the V-shaped rod 19 moves upward and squeezes one end of the trigger rod 20, so that the trigger rod 20 rotates. When the trigger rod 20 rotates to the horizontal and continues to rotate upward from the horizontal, the upper side of the V-shaped rod 19 limits and fixes the trigger rod 20, and under the tension of the spring 21, the trigger rod 20 is pulled back. The force drives the slider 14 to move upward, and the slider 14 drives the push rod 15 to pop out and insert into the movable groove 16, performing secondary limit fixation on the fixed block 6 to increase the clamping stability of the fixed block 6. When the knob is turned to the maximum value, slowly turn the knob disk 9 left and right and continue to press the plug-in rod 11 downward by hand. When the plug-in rod 11 is inserted downward into the plug-in slot 10, the positioning of the knob disk 9 is completed, and one splicing block 2 is fixed. Repeat the above operation to complete the installation of another splicing block 2 and complete the installation of the device.
