Description

Technical Field

[0001] The utility model relates to the technical field of composite air ducts, in particular to a composite air duct reinforcement structure. Background Art

[0002] Composite duct is a new type of duct material, which is lighter, stronger, more corrosion-resistant and easier to install than traditional metal duct. The inner and outer wall materials of composite duct are both polymer materials, and the middle layer is reinforced with steel wire skeleton to form a composite structure, so it is called composite duct. It is suitable for a variety of spaces, such as commercial places, stadiums, electronics, food factory production places, supermarkets and other business places. It can be directly connected to the outlet of fan equipment or connected to iron duct.

[0003] At present, when installing the composite air duct, in order to avoid deformation of the top, it is necessary to support and reinforce it to ensure the strength of the composite air duct. The existing reinforcement method is mainly to perform reinforcement operation through a threaded screw. During reinforcement, it is necessary to drill a hole on the surface of the composite air duct, then pass the threaded screw through the air duct, and finally complete the reinforcement through the combination of a nut and a gasket. During use, this reinforcement method will cause cold bridges and condensation and dripping (i.e., the air humidity in the air duct is high, and the temperature difference between the inside and outside of the duct is large, which easily causes cold bridge condensation). At the same time, the installation position of the threaded screw is generally in the middle of the composite air duct. When the composite air duct is long, the connection operation between the nut and the threaded screw inside the composite air duct is very inconvenient. For this reason, a composite air duct reinforcement structure is proposed. Utility Model Content

[0008] Furthermore, a non-slip pad is fixedly connected to one side of the outer surface of the metal plate, and the non-slip pad abuts against the inner wall of the composite air duct body to increase the friction of the metal plate and prevent the metal plate and the inner wall of the composite air duct body from slipping.

[0009] Furthermore, the plurality of pushing assemblies all include a screw rod, and the screw rod is rotatably mounted on the inner top of the support seat, a nut is threadedly sleeved on the outer surface of the screw rod, and the nut is fixedly mounted inside the through groove, and the screw rod rotates to drive the movable plate to move through the nut.

[0010] Furthermore, the synchronous drive assembly includes a driving screw head, and the driving screw head is arranged on the outside of the support seat, one end of the driving screw head is fixedly connected to a rotating shaft, and the rotating shaft passes through the outer wall of the support seat and extends to the interior and is rotatably connected thereto, a plurality of worms are fixedly sleeved on the outer surface of the rotating shaft, the outer surfaces of the plurality of worms are meshingly connected with worm wheels, and the worm wheels are fixedly sleeved on the outer surface of the screw, and the worm and worm wheel cooperate to have a self-locking property, and when the worm does not rotate, the worm wheel cannot rotate.

[0011] Furthermore, the mounting holes of the sealing flange and the mounting flange are located in the same position, which is beneficial for connecting two adjacent composite pipelines.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the composite air duct reinforcement structure, through the arranged positioning frame, abutment plate, support seat, movable plate, through groove, pushing assembly and synchronous drive assembly, adopts an inserted positioning expansion installation to replace the original threaded screw reinforcement method when reinforcing a long composite air duct.
