Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0026] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0027] This embodiment discloses a fixing structure for fire-fighting smoke exhaust ducts, including a fixing plate 1, mounting components, a support plate 7, and snap-fit ​​components; the fixing plate 1 consists of two pieces, arranged side by side with a gap, and connected as a whole by a fixing support plate 2; the mounting components consist of multiple sets, respectively connected to the bottom of the two fixing plates 1 at intervals, each set of mounting components including two vertically spaced mounting plates 3, the outer mounting plate 3 having multiple pairs of insertion interfaces 8 spaced through from top to bottom, and the inner... The mounting plate 3 has a recessed insertion groove 4 on its side wall near the outer side, corresponding to the insertion interface 8; the support plate 7 has four through-holes 71 on both sides corresponding to the two sides of the mounting plate 3, which are adapted to fit with the mounting plate 3 so that the support plate 7 can be fitted onto the two opposing mounting plates 3 from bottom to top to support the air duct; the snap-fit ​​is detachably inserted into the insertion interface 8, and its end extends into the insertion groove 4, and the top of the snap-fit ​​abuts against the bottom of the support plate 7.

[0028] In the above embodiment, through the functions of the mounting plate 3, the plug interface 8, the plug slot 4, the support plate 7, the sleeve interface 71, and the snap fastener, the air duct is lifted and clamped between the two mounting plates 3. Then, the sleeve interface 71 is aligned with the mounting plate 3, and the support plate 7 is sleeved on the two mounting plates 3. Finally, the snap fastener is inserted into the plug interface 8 and the plug slot 4 to fix it on the mounting plate 3 and support the support plate 7. In this way, the entire air duct can be supported. The whole process is relatively convenient, takes less time, and has high installation efficiency. Moreover, the staff only needs to lift the air duct upwards, without pushing the air duct. Fewer staff are required, and the labor cost is low.

[0029] In the above embodiment, two fixing plates 1 are fixed to the ceiling by fixing bolts. Each set of installation components includes two mounting plates 3. The two mounting plates 3 are vertically fixed to the bottom of the fixing plate 1 and are arranged relatively at intervals. The two mounting plates 3 can improve the support effect of the entire air duct and improve the support strength of the entire device. There are two pairs of plug interfaces 8. The two pairs of plug interfaces 8 are opened from top to bottom at intervals on the outer mounting plate 3. Each pair of plug interfaces 8 consists of two plug interfaces 8, which are arranged side by side at intervals. The plug groove 4 is recessed on the inner mounting plate 3 corresponding to the two pairs of plug interfaces 8, so that the snap-fit ​​parts can pass through the plug interfaces 8 from the outside to the inside and be inserted into the plug groove 4 for fixation. There are two sleeve interfaces 71 on each side. The two sleeve interfaces 71 are arranged at intervals corresponding to the two mounting plates 3. The diameter of the sleeve interface 71 can be slightly larger than the outer diameter of the mounting plate 3, so that the support plate 7 can be fitted onto the mounting plates 3 on both sides through the sleeve interfaces 71 on both sides, so as to surround the air duct sandwiched between the two mounting plates 3.

[0030] In the above embodiment, the fixing plate 1 is first fixed to the ceiling, then the air duct is lifted and clamped between the two mounting plates 3, then the sleeve interface 71 of the support plate 7 is aligned with the mounting plate 3 and lifted up to above the insertion interface 8, then the snap-fit ​​is inserted into the insertion interface 8 and the insertion slot 4 to support the support plate 7, and the support plate 7 is fixed on the two mounting plates 3, thereby supporting the air duct.

[0031] In one optional embodiment, the snap-fit ​​component includes an inverted L-shaped limiting block 5. Two snap-fit ​​plates 6 are horizontally connected at intervals to the end of the limiting block 5 near the mounting plate 3, corresponding to the insertion interface 8. The two snap-fit ​​plates 6 are respectively adapted to the insertion interface 8 and the insertion slot 4.

[0032] Preferably, the top ends of the two snap-fit ​​plates 6 are respectively provided with limiting grooves 61, and the bottom end of the support plate 7 is located between two adjacent sleeve interfaces 71 and is connected to the limiting grooves 61 with limiting protrusions 72, which are adapted to fit with the limiting grooves 61 to fasten the snap-fit ​​plates 6 to the insertion interface 8 and the insertion groove 4.

[0033] Furthermore, the limiting protrusion 72 and the limiting groove 61 are arranged in the shape of an inverted frustum.

[0034] In the above embodiment, when the end of the snap-fit ​​plate 6 is fully inserted and abuts against the inner wall of the insertion slot 4, the limiting slot 61 is exactly aligned with the limiting protrusion 72. When the support plate 7 moves downward and abuts against the snap-fit ​​plate 6, the limiting protrusion 72 at the bottom of the support plate 7 will be just locked into the limiting slot 61. Through the action of the limiting protrusion 72 and the limiting slot 61, the snap-fit ​​plate 6 can be locked, preventing the snap-fit ​​plate 6 from being moved outward and disengaged from the insertion interface 8 and the insertion slot 4 by external force, which would cause the support plate 7 to fall down.

[0035] In one optional embodiment, a straight guide rail 73 is formed through the end face of the support plate 7 between the two sleeve interfaces 71. A pair of clamping components are slidably connected to the guide rail 73, which are suitable for clamping the air duct from both sides to fix it. The clamping components can further clamp the air duct to prevent it from shaking or becoming unstable.

[0036] Preferably, the clamping assembly includes a clamping block 9, a moving rod 10, and a locking sleeve 12. The clamping block 9 is vertically disposed on the guide rail 73. The moving rod 10 is vertically connected to the bottom end of the clamping block 9 and extends downward through the guide rail 73 at a predetermined distance. The portion of the moving rod 10 located in the guide rail 73 is a smooth rod structure, and the portion located below the guide rail 73 is a threaded structure. The locking sleeve 12 is sleeved on the threaded portion of the moving rod 10 and screwed into the threaded portion.

[0037] In the above embodiment, the width of the clamping block 9 is less than the width of the support plate 7, and the length is half the length of the duct. The two clamping blocks 9 are respectively arranged opposite to each other and have a gap with the end face of the support plate 7. The moving rod 10 is vertically inserted in the guide rail 73. Its top end is fixedly connected to the clamping block 9, and its bottom end extends downward for a certain length. The part located inside the guide rail 73 is a smooth rod structure, and the part located below the guide rail 73 is a threaded structure. The smooth rod structure allows the moving rod 10 to drive the clamping block 9 to move back and forth, thereby adjusting the distance between the two clamping blocks 9 to adapt to ducts of different sizes. The threaded structure allows the locking sleeve 12 to be screwed in and abut against the bottom of the support plate 7 to fix the moving rod 10 and prevent the moving rod 10 from driving the clamping block 9 to move.

[0038] In one optional embodiment, the two side walls of the guide rail 73 are respectively provided with grooves 74 in the shape of a straight line. Slider blocks 11 are connected to the outer sides of the smooth rod structure of the moving rod 10 corresponding to the grooves 74, and the sliders 11 are adapted to the grooves 74. This improves the smoothness of movement of the moving rod 10 in the guide rail 73 and the movement of the clamping block 9 on the support plate 7.

[0039] In one optional embodiment, a handrail block 13 is radially connected to the outer wall of the locking sleeve 12; rubber pads are connected to both the end of the clamping block 9 away from the sleeve interface 71 and the top end of the locking sleeve 12. The handrail block 13 facilitates the rotation of the locking sleeve 12, and the rubber pads ensure that the clamping block 9 is in tight contact with the air duct, and that the locking sleeve 12 is in tight contact with the bottom end of the support plate 7, resulting in a good fixing effect.

[0040] In one optional embodiment, the lower end of one side of the fixing plate is provided with an L-shaped first notch, and the upper end of the other side is provided with a second notch that matches the first notch. During assembly, the first notch of one set of fixing plates and the second notch of the adjacent set can be aligned and superimposed, so that the fixing plates of the adjacent sets can be tightly and seamlessly connected together. Then, they can be fixed to the ceiling with fixing bolts, so that the fixing plates are in a whole state, supporting each other, improving the tightness and aesthetics of the fixing plates.

[0041] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any changes and modifications made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of protection of the present invention.
