[0024] The top of the tray 1 is provided with four groups of grooves 11, and the inner bottom of the grooves 11 is fixedly provided with two groups of teeth 12 in a mirror-image manner, and the inclination of the teeth 12 is opposite. Two groups of fixed blocks 13 are fixedly provided at the bottom of one side of the fixed splint 8, and a movable rod 14 is slidably penetrated through the center of the fixed block 13, and an adjusting disk 15 is fixedly provided at the top of the movable rod 14, and a spring 16 is fixedly provided between the bottom end of the adjusting disk 15 and the top end of the fixed block 13, and a locking block 17 is fixedly provided at the bottom end of the movable rod 14, and the locking block The bottom end of 17 is triangular, and the inclination direction of the triangular slope is in the opposite direction of the inclination of the teeth 12 directly below. When working, after the staff fixes the duct anti-seismic bracket to the indoor ceiling, the duct needs to be fixed. In order to enable the duct anti-seismic bracket to fix ducts of different sizes and circular ducts, the duct is first located between the fixed clamping plates 8 directly above the tray 1. The staff turns the handle 4, and the screw 3 rotates while driving the moving rod 5 to move relative to it. At the same time, the moving block 7 drives the fixed clamping plate 8 to move, and the duct The tube is clamped and fixed, and the rubber pad 10 increases the friction with the air duct. At the same time, when fixing a square air duct, the upper and lower ends of the fixing clamp 8 are vertical, which can fix it. When fixing a circular air duct, the middle of the fixing clamp 8 is a concave V-shaped structure, which can fix the circular air duct, thereby improving the scope of application. In order to prevent the position of the fixing clamp 8 from shifting after the air duct is fixed, causing the air duct to loosen, when the fixing clamp 8 clamps the air duct, it drives the fixing block 13 to move while moving, and the fixing block 13 drives the movable rod 14 to move, and the movable rod 14 The locking block 17 is driven to move, and the locking block 17 is inserted into the gap between the teeth 12 under the elastic potential energy of the spring 16. When the locking block 17 moves toward the center point again, the movement is not restricted because its bottom is consistent with the inclination direction of the teeth 12. When the fixed splint 8 moves toward the edge of the tray 1 due to external force, the position of the fixed splint 8 is always limited because the bottom end of the locking block 17 is stuck in the gap of the teeth 12. When disassembly is required, only the adjusting disk 15 needs to be pulled to make the locking block 17 leave the teeth 12 to stop fixing the air duct, thereby ensuring the fixing stability of the air duct.

[0025] Furthermore, an insertion rod 18 is movably inserted into the top of the sleeve rod 9, and an array of through holes 19 is opened on one side of the insertion rod 18. A fixing bolt 20 is provided on one side of the sleeve rod 9 through a threaded rotation. The fixing bolt 20 is rotated and penetrates the through hole 19. A first fixing plate 21 is fixedly provided on the top of the insertion rod 18, and first mounting ears 22 are fixedly provided on the tops of both sides of the sleeve rod 9. An oblique support rod 23 is rotatably provided on the first mounting ear 22 by a rotating rod. A second fixing plate 24 is provided at the other end of the oblique support rod 23, and a second mounting ear 25 is fixedly provided at the bottom center of the second fixing plate 24. The two mounting ears 25 are rotatably connected to one end of the diagonal support rod 23 through a rotating rod. Fixing screw holes 26 are provided at the four corners of the first fixing plate 21 and the second fixing plate 24. When working, firstly, the extension length of the insertion rod 18 needs to be adjusted according to the installation height of the air duct. First, the insertion rod 18 is pulled out. After determining the extension length, the fixing bolt 20 is rotated to insert it into the through hole 19 at the corresponding position, and the position of the insertion rod 18 and the sleeve rod 9 is fixed. Then, the first fixing plate 21 is fixed to the top surface of the wall through the fixing screw hole 26, and then the diagonal support rod 23 is rotated to adjust its angle and then the second fixing plate 24 is fixed to the top surface of the wall through the fixing screw hole 26.

[0026] Working principle: First of all, the extension length of the plug rod 18 needs to be adjusted according to the installation height of the air duct. First, pull out the plug rod 18, and after determining the extension length, rotate the fixing bolt 20 to insert it into the through hole 19 at the corresponding position, fix the position of the plug rod 18 and the sleeve rod 9, and then fix the first fixing plate 21 to the top surface of the wall through the fixing screw hole 26, and then rotate the diagonal support rod 23, adjust its angle, and then fix the second fixing plate 24 to the top surface of the wall through the fixing screw hole 26; after the staff fixes the air duct anti-seismic bracket to the indoor ceiling, the air duct needs to be fixed. In order to enable the air duct anti-seismic bracket to fix air ducts of different sizes and at the same time fix the circular air duct, first the air duct is located between the fixed splints 8 just above the tray 1, and the staff rotates the handle 4. While the screw 3 rotates, the moving rod 5 is driven to move relatively, and at the same time, the moving block 7 drives the fixed splint 8 to move, clamps and fixes the air duct, and the rubber pad 10 increases the friction with the air duct. At the same time, when the square air duct is fixed When the air duct is fixed, the upper and lower ends of the fixing clamp 8 are vertical, which can fix it. When fixing a circular air duct, the middle of the fixing clamp 8 is a concave V-shaped structure, which can fix the circular air duct, thereby improving the scope of application. In order to prevent the position of the fixing clamp 8 from shifting after the air duct is fixed, causing the air duct to loosen, when the fixing clamp 8 clamps the air duct, it drives the fixing block 13 to move, the fixing block 13 drives the movable rod 14 to move, the movable rod 14 drives the locking block 17 to move, and the locking block 17 is in the spring 16 is inserted into the gap between the teeth 12 under the elastic potential energy, and when the locking block 17 moves toward the center point again, the movement is not restricted because its bottom is consistent with the inclination direction of the teeth 12. When the fixed splint 8 moves toward the edge of the tray 1 due to external force, the bottom end of the locking block 17 is stuck in the gap between the teeth 12, and the position of the fixed splint 8 is always limited. When it needs to be disassembled, it only needs to pull the adjusting disk 15 to make the locking block 17 leave the teeth 12 to stop fixing the air duct, thereby ensuring the fixing stability of the air duct.
