[0002] Ventilation ducts are widely used in hotels, guesthouses, supermarkets, office buildings, government agencies, small villas and other buildings. Since the ducts are hollow and thin, they are not suitable for pre-embedding in concrete floors. They are usually installed on the roof ceiling with the help of brackets. Another important function of earthquake-resistant brackets is earthquake resistance. When vibration occurs, the ducts are prone to swing and fall off, or become disconnected due to swinging in all directions. The earthquake-resistant brackets can greatly improve the installation stability of the ducts.

[0003] However, the current two-way seismic-resistant bracket for air ducts still has the following shortcomings: when the current two-way seismic-resistant bracket for air ducts is installed, the connection between the support frame and the bracket is mostly connected by fasteners, and the height of the support frame is often unable to be adjusted. Therefore, the angle when it is connected to the roof is relatively fixed. Secondly, if the direction of the support frame needs to be adjusted during installation, it also needs to be disassembled and reassembled, which is time-consuming and labor-intensive. Secondly, the clamping and limiting work of the air duct is relatively inconvenient, and it often cannot be adjusted according to the size of the air duct, and its applicability is poor.

[0004] Therefore, how to provide a bidirectional earthquake-resistant bracket for an air duct is an urgent problem to be solved by those skilled in the art. Utility Model Content

The outer side and the front side of the movable seat 3 are movably installed with a support frame 8 through a rotating shaft. During operation, the staff needs to hold one side of the movable seat 3 and then rotate the screw rod 2. At this time, the movable seat 3 can be prevented from rotating when the screw rod 2 rotates, and it can be ensured that the movable seat 3 can be displaced up and down when the screw rod 2 rotates;

[0026] Secondly, a plurality of mounting holes 6 are provided in the fixing rod 1, and the fixing rod 1 can be fixedly installed on the top of the wall by using the mounting holes 6 in conjunction with expansion bolts;

[0027] In addition, a fixing seat 9 is movably installed on the top of the support frame 8 through a rotating shaft, and holes for fixing are opened on both sides of the top of the fixing seat 9. The fixing seat 9 can be used in conjunction with expansion bolts to complete the fixed connection with the wall top;

[0028] It should be noted that a hexagon socket head 19 is fixedly installed at the bottom of the movable column 17 and below the bottom rod 4. The staff can insert a hexagonal wrench into the hexagon socket head 19 to rotate the screw rod 2;

[0029] In this embodiment, it can first be fixed on the roof above the air duct through the fixing rod 1, and then the plug block 14 can be inserted into the slot 18, and then the screw 7 can be screwed into the screw hole 15 to complete the fixation. Then the staff can hold one side of the movable seat 3 and rotate the screw 2. At this time, the movable seat 3 can be moved up or down to adjust the height. After adjusting the appropriate height, it can be fixed to the roof through the fixing seat 9. At this time, the support frame 8 can complete the support and earthquake resistance work from both sides.

[0030] refer to Figure 1-3 A slide groove 10 is provided in the center of the top of the bottom rod 4, and a bolt 11 is movably installed in the slide groove 10. The slide groove 10 is an inverted T-shape, and the head end of the bolt 11 is placed at the bottom of the inner side of the slide groove 10, so that the bolt 11 can slide left and right in the slide groove 10, but cannot fall off in the slide groove 10;

[0031] A through hole 12 is provided at the bottom of one side of the clamping plate 5, and a bolt 11 passes through the through hole 12. There are two groups of clamping plates 5, and the two groups of clamping plates 5 are symmetrically installed on both sides of the top of the bottom rod 4 through two groups of bolts 11, and nuts 13 are screwed on the bolts 11. The bottom of the clamping plate 5 is designed to be open, and the opening at the bottom of the clamping plate 5 is placed on the bottom rod 4, so as to ensure that the clamping plate 5 can stably move left and right;

[0032] In this embodiment, the two groups of clamps 5 can be placed on both sides of the air duct respectively, and then the distance between the two groups of clamps 5 can be adjusted by sliding the bolts 11 in the slide groove 10, and the clamps 5 can be fixed by rotating the nuts 13, so that the clamps 5 can complete the clamping and limiting of the two sides of the air duct.

[0033] Working principle: First, the fixing rod 1 can be fixed on the roof above the air duct by passing the expansion bolt through the installation hole 6, and then the bottom rod 4 can be placed under the air duct for support, and the plug blocks 14 on the top of the screw rods 2 on both sides can be inserted into the slots 18, and then the screws 7 are screwed in to fix it. Then, hold the movable seat 3 with one hand and rotate the screw rod 2 with the other hand. The screw rod 2 can be rotated under the plug block 14 through the movable block 16. When the screw rod 2 is located in the screw hole of the movable seat 3 and rotates, the movable seat 3 can be driven to move up and down. At this time, the support frame 8 can be driven to move up and down, and the rotating screw rod 2, if the movable seat 3 is not held, the movable seat 3 will rotate with the screw rod 2 to adjust the position of the support frame 8. After the movable seat 3 moves up and down to a suitable position, the fixed seat 9 on the top of the support frame 8 can be fixed to the roof. At this time, the support frame 8 can complete the lateral support and reinforcement work, thereby achieving a better earthquake-resistant effect. When the pipeline is placed above the bottom rod 4, the two groups of clamps 5 can slide left and right in the slide groove 10 through the bolts 11 to adjust the spacing. After the two groups of clamps 5 are moved to both sides of the air duct, the nuts 13 can be rotated, and the fixing work of the clamps 5 can be completed at this time.
