[0002] Smoke exhaust ducts are an important part of the fire protection system. When a fire occurs in a building, the smoke exhaust ducts can exhaust the toxic smoke indoors to the outside and supply natural air to the room, providing precious time for trapped people to escape and firefighters to rescue.

[0003] The authorized patent with known application number: CN202320399572.6 discloses a seismic-resistant bracket for an assembled fire-fighting smoke exhaust duct. Its background technology raises the problem that "the existing mounting bracket has poor overall seismic resistance, resulting in insufficient support and fixation of the smoke exhaust duct". To this end, the technical solution to this problem is "including a support base, a clamping mechanism and a fixing bolt, one side of the clamping mechanism is inserted into the interior of the support base, the clamping mechanism is movably connected to the support base through four symmetrically arranged fixing bolts, and a plurality of compression springs are fixedly connected to the upper surface of the clamping mechanism, and the plurality of compression springs are symmetrically arranged between the four fixing bolts, and a buffer pad is arranged inside the clamping mechanism".

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: although the technical solution provided achieves the effect of making the connection between the bracket as a whole and the wall more stable, when it is used, the distance between the two plug-in plates is fixed and cannot be adjusted, which makes it inconvenient to adapt and fix the air ducts according to different widths, and the air ducts are clamped and fixed by bolts, and the disassembly and assembly steps are relatively cumbersome and time-consuming, which reduces the convenience and applicability of the air duct installation.

[0015] The adjusting component comprises an adjusting screw rotatably connected to one side of the top of the supporting base plate and a guide rod fixedly connected to the other side of the top of the supporting base plate. The movable plate is threadedly connected to the surface of the adjusting screw and is slidably connected to the guide rod.

The trapezoidal limit block is squeezed by the limiting slot, so that the trapezoidal limit block drives the movable rod to slide into the storage slot and compresses the spring. When the clamping block contacts and clamps the tube, the pushing is stopped. At this time, the extrusion force on the trapezoidal limit block disappears, and under the action of spring one, the trapezoidal limit block is driven to move down and reset and clamp into the corresponding limiting slot to fix the clamping block. Therefore, the effect of quick adaptation and clamping according to the width of the air duct is achieved, and there is no need to frequently tighten the bolts for clamping, which reduces the time for installation and disassembly of the air duct, effectively improving the convenience and flexibility of disassembly and assembly of the air duct as well as the scope of application.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0029] See also Figure 1 - Figure 4 The utility model provides a fire smoke exhaust duct earthquake-resistant bracket, comprising: a supporting bottom plate 1, and two groups of limit slots 2 are symmetrically opened on the top of the supporting bottom plate 1;

[0030] Two clamping blocks 3 are symmetrically slidably clamped on the top of the supporting base plate 1, and a storage groove is provided on one side of the clamping block 3;

[0031] Two movable rods 4 are symmetrically arranged in the receiving groove and slidably connected to the clamping block 3;

[0032] A trapezoidal limit block 5 fixedly connected to the bottom end of the movable rod 4 and engaging with the limit slot 2;

[0033] A spring 6 is sleeved on the surface of the movable rod 4 and its two ends are respectively connected to the trapezoidal limit block 5 and the clamping block 3;

[0036] The technical solution provided by this embodiment is as follows: when installing the air duct, the air duct is placed on the supporting base plate 1, and then the two clamping blocks 3 are pushed to slide close to each other. At this time, the trapezoidal limit block 5 is squeezed by the inner wall of the limit slot 2 during the sliding process of the clamping block 3, and under the action of the squeezing force, the trapezoidal limit block 5 moves into the storage slot, and at the same time drives the movable rod 4 to slide into the clamping block 3, so that the spring 6 is compressed to produce elastic deformation. When the clamping block 3 contacts and clamps the pipe, the pushing stops. At this time, the trapezoidal limit block 5 is squeezed The force disappears, and under the action of spring 1 6, the trapezoidal limit block 5 is driven to move down and reset into the corresponding limit slot 2 to fix the clamping block 3. Conversely, when disassembling the air duct, it is only necessary to lift the pulling block 7 to drive the trapezoidal limit block 5 and the limit slot 2 to separate, and move the clamping block 3 to release the fixation of the air duct. Therefore, the effect of fast adaptation and clamping according to the width of the air duct is achieved, and there is no need to frequently tighten the bolts for clamping, which reduces the time of air duct installation and effectively improves the convenience, flexibility and scope of application of air duct installation.

At the same time, when it is vibrated, the buffer pad 9, the damper 11 and the spring 13 are used in combination to buffer and reduce shock, so as to avoid damage or loosening of the air duct caused by vibration, thereby ensuring the use effect and installation stability of the air duct.
