[0002] Fire-resistant ventilation ducts are a key component of building fire protection systems, primarily used for smoke extraction and ventilation during fires to ensure personnel evacuation and fire rescue. Smoke extraction refers to the removal of smoke and harmful gases generated at the fire scene from the building through smoke extraction fans and ducts. Ventilation refers to the supply of fresh air to the fire scene through the fire-resistant ventilation ducts via a make-up air system during a fire, maintaining a negative pressure state indoors and preventing smoke backflow.

[0003] Currently, when installing ventilation ducts, it is often necessary to use fixing components to support and fix them. Existing fixing components mostly use a hanger structure to suspend and fix the ventilation duct to the top of the building wall. However, since the hanger is often an integrated structure, and the ventilation ducts are of different sizes, it is difficult to effectively adapt them. After the duct is placed on the hanger support, there is still a lot of room for movement, which makes it unstable and greatly affects stability and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fire ventilation pipe installation and fixing component. By symmetrically arranging two sets of movable seats, positioning columns, slides, and sliders on a support plate, and with the cooperation of structures such as cavities, toothed columns, and gears, after the fire ventilation pipe is placed on the support plate, the movable seats can be controlled to move the two sets of positioning columns close together and abut against both sides of the fire ventilation pipe. Conversely, the two sets of positioning columns can be controlled to move away from each other. Thus, the distance between the two sets of positioning columns can be adjusted according to the pipe model, so that the fire ventilation pipe can be quickly and securely fastened to the support plate. This effectively adapts to the installation and fixing of various types of fire ventilation pipes, and the operation is simple and convenient, greatly ensuring stability and safety, thereby solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire ventilation pipe installation and fixing assembly, comprising:

[0006] A support plate, wherein both ends of the top side of the support plate are provided with connectors;

[0007] The cavity is located inside the support plate, and symmetrical toothed columns that can move towards or away from each other are arranged on both sides of the cavity. A slider is fixed at the opposite end of each toothed column. The top side of the support plate has slides that match the sliders.

[0013] Preferably, the limiting structure includes a cavity at the bottom of the connecting rod, a spring is provided inside the cavity, limiting heads are symmetrically fixed at both ends of the spring, one end of the limiting head extends out of the connecting rod relative to the spring, and multiple sets of limiting holes matching the limiting heads are symmetrically provided on both sides of the connecting column.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] By symmetrically arranging two sets of movable seats, positioning columns, slides, and sliders on the support plate, and with the cooperation of structures such as cavities, toothed columns, and gears, after the fire ventilation pipe is placed on the support plate, the movable seats can be controlled to drive the two sets of positioning columns to quickly approach and press against both sides of the fire ventilation pipe. Conversely, the two sets of positioning columns can be controlled to move away from each other.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figures 1-6 The fire ventilation duct installation and fixing assembly shown includes:

[0029] Support plate 1, with connectors 2 provided at both ends of the top side of support plate 1;

[0030] The connector 2 includes a connecting column 200 and a connecting rod 201. The bottom end of the connecting column 200 is fixedly connected to the support plate 1, and the bottom end of the connecting rod 201 can be inserted into the sliding cavity 19. The top end of the connecting rod 201 is provided with a fixing seat 3, and both ends of the fixing seat 3 are provided with fixing holes. A limiting structure is provided between the connecting rod 201 and the connecting column 200. Based on this, by nailing the fixing seat 3 to the roof with screws, and in conjunction with the connector 2, the support plate 1 can be suspended and fixed, thereby allowing the fire ventilation pipe to be installed on the support plate 1.

[0031] The limiting structure includes a cavity 22 located at the bottom of the connecting rod 201. A spring 23 is provided inside the cavity 22. Limiting heads 21 are symmetrically fixed at both ends of the spring 23. One end of the limiting head 21 extends out of the connecting rod 201 relative to the spring 23. Multiple sets of limiting holes 20 matching the limiting head 21 are symmetrically provided on both sides of the connecting column 200.

[0032] By pressing the limiting head 21, the limiting head 21 slides within the cavity 22 and compresses the spring 23. Then, the limiting head 21 can exit the limiting hole 20 and retract into the cavity 22, thus releasing the fixation. Afterward, the connecting rod 201 can be pulled to slide within the connecting column 200. When the limiting head 21 is released, the spring 23 rebounds, allowing the limiting head 21 to reset and insert into the corresponding limiting hole 20 for re-locking. This allows for quick adjustment of the length of the connecting piece 2, thereby adjusting the support plate 1's support and fixing height for the fire ventilation pipe, greatly improving the usability.

[0033] The cavity 4 is located inside the support plate 1, and symmetrical toothed columns 7 that can move towards or away from each other are arranged on both sides of the cavity 4. Slider 6 is fixed at the opposite ends of the two toothed columns 7. Slides 5 that match the slider 6 are opened at both ends of the top side of the support plate 1. The top ends of the two sliders 6 pass through the slides 5 and are provided with movable seats 9. Positioning columns 10 are fixed at both ends of the top side of the movable seats 9. The top end of the positioning columns 10 is provided with a pressing structure. Gear 8 is rotatably connected to the middle of the cavity 4 through a rotating shaft, and the two toothed columns 7 mesh with the gear 8. The support plate 1 is provided with a driving structure, which is used to drive the toothed columns 7 to move.

[0034] The drive structure includes a threaded rod 11 rotatably connected to one end of the cavity 4 via a bearing, wherein a toothed post 7 is threadedly connected to the outside of the threaded rod 11, and one end of the threaded rod 11 extends to the outside of the support plate 1 and is provided with a handle 12.

[0035] T-shaped limiting blocks 13 are fixed to the adjacent outer ends of the two toothed columns 7, and T-shaped limiting grooves 14 matching the T-shaped limiting blocks 13 are opened on both sides of the cavity 4. Based on this, by setting the T-shaped limiting blocks 13 and the T-shaped limiting grooves 14, the stable movement of the toothed column 7 along the straight line can be greatly ensured.

[0036] In use, the fire ventilation pipe can be placed on the support plate 1. By turning the handle 12, the handle 12 can drive the threaded rod 11 to rotate, causing the threaded rod 11 to drive the toothed column 7 to move in the cavity 4. Then, under the meshing of the toothed column 7 and the gear 8, the two toothed columns 7 can be driven to move towards each other. After that, the toothed column 7 drives the movable seat 9 to move through the slider 6, thereby causing the movable seat 9 to drive the positioning column 10 to move. Then, the two sets of positioning columns 10 move closer to each other and abut against the two sides of the fire ventilation pipe. Conversely, the two sets of positioning columns 10 can be controlled to move away from each other. Thus, the distance between the two sets of positioning columns 10 can be adjusted according to the pipe model, so that the fire ventilation pipe can be quickly and securely fastened to the support plate 1. This can effectively adapt to the installation and fixing of various types of fire ventilation pipes, and the operation is simple and convenient, greatly ensuring stability and safety.

[0037] The pressing structure includes a threaded channel 15 located at the top of the positioning post 10, a stud 16 inside the threaded channel 15, the top of the stud 16 extending outside the threaded channel 15, and a pressure plate 17.

[0038] After the positioning post 10 clamps the fire ventilation pipe, the pressure plate 17 at the top of the positioning post 10 can be screwed on. With the screw connection of the threaded channel 15 and the stud 16, the pressure plate 17 can be raised and lowered, so that the pressure plate 17 can be lowered and pressed against the top side of the fire ventilation pipe. With the cooperation of multiple sets of pressure plates 17, the fire ventilation pipe can be further limited and reinforced, so that the fire ventilation pipe can be more stable and reliable, and the use effect is better.

[0039] Rubber pads 18 are provided on the inner sides of both the pressure plate 17 and the positioning post 10. Based on this, the elasticity of the rubber pads 18 can further enhance the tightness when pressed together.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
