Description

Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to a composite air duct structure. Background Technology

[0002] A search revealed patent number CN202221669001.1, which discloses a composite duct structure. The structure includes a rectangular duct body, each comprising a main body. Flanges are located at the center of all four sides of one end of the main body. Each flange has a connecting arm and a slot structure located on one side of the connecting arm. Two rectangular duct bodies are present, with the flanges at each end corresponding to each other and connected by H-shaped locking pins. Each H-shaped locking pin has a first locking arm, a second locking arm, and an intermediate arm connecting the first and second locking arms. Each H-shaped locking pin is inserted into the slot structure of one rectangular duct body's end flange via its first locking arm and into the slot structure of the adjacent flange at the other rectangular duct body's end via its second locking arm. Compared to the prior art where adjacent flanges are fixed with multiple bolts, the above example uses only one H-shaped locking pin to fix adjacent flanges, requiring fewer H-shaped locking pins and resulting in higher installation efficiency.

[0003] The aforementioned patent improves installation efficiency by using H-shaped locking pins. However, in actual use, it has been found that composite ducts often lack adequate protection during transportation. For example, simple foam boards or corrugated cardboard boxes are often used for filling and wrapping to reduce vibration and impact during transport. While this does reduce deformation caused by vibration, severe impacts can directly lead to dents on the duct surface, affecting its performance and aesthetics. Therefore, we propose a composite duct structure. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] This utility model provides a composite duct structure that can solve the problem of deformation caused by collisions during transportation. The specific solution is as follows:

[0006] A composite duct structure includes a duct body, an insulated pipe fixedly connected inside the duct body, a reinforcing component inside the insulated pipe, and the outer side wall of the insulated pipe being fitted and connected to the inner side wall of the duct body. Protective components are provided on both sides of the duct body, each protective component including an upper support and a lower support. Multiple reinforcing ribs are vertically connected between the upper and lower supports, and steel connecting rods are fixedly installed between the multiple vertically arranged reinforcing ribs. A connecting plate is fixedly installed between the left and right sets of upper supports, and the bottom sides of the connecting plate are connected to the top wall of the insulated pipe through connecting parts.

[0007] As a preferred technical solution of this utility model, the reinforcing component includes a fixing plate, which is fixedly installed on the bottom side of the inner wall of the insulation pipe and connected by bolts. A support plate is fixedly installed at the top center of the fixing plate, and a ventilation groove is opened in the middle of the support plate.

[0008] As a preferred embodiment of this utility model, multiple support columns are fixedly connected to both sides of the support plate, the ends of the multiple support columns are fitted into the two inner side walls of the insulation pipe, and the top of the support columns is fixedly connected to the support frame.

[0009] As a preferred embodiment of this utility model, multiple reinforcing blocks are fixedly connected to both ends of the support frame, and the top wall of the support frame is fixed to the inner bottom wall of the insulation pipe to enhance the rigidity and support of the insulation pipe.

[0010] As a preferred technical solution of this utility model, the connecting component includes a steel block, which is disposed on the top wall of the insulation pipe. Both sides of the top of the steel block are fixedly connected to docking seats, and the top of the docking seats is connected to a fixing rod. The fixing rod passes through the air duct body and connects to the connecting plate.

[0011] As a preferred embodiment of this utility model, a sealing gasket is pre-set at the intersection of the fixing rod and the duct body.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] By setting a protective structure consisting of an upper support and a lower support on the outer wall of the duct body, and setting several reinforcing ribs and connecting rods between the upper support and the lower support, the side wall of the duct body is protected, which can greatly reduce the deformation of the duct body caused by vehicle vibration during transportation.

[0014] By adding an insulation pipe inside the duct body, water vapor in the air can be prevented from condensing into water droplets when cold air blows inside the duct, thus preventing condensation on the outer wall of the duct. Furthermore, the insulation pipe is reinforced with additional components to further improve the rigid support effect inside the insulation pipe.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0024] See Figures 1-4This utility model provides a composite duct structure, including a duct body 1, with an insulation pipe 2 fixedly connected inside the duct body 1. The insulation pipe 2 has a reinforcing component inside, and the outer side wall of the insulation pipe 2 is fitted and connected to the inner side wall of the duct body 1. By setting the insulation pipe 2, condensation and water droplet problems are avoided, protecting the duct and the environment. Furthermore, when the surface temperature of the cold air duct is lower than the dew point temperature of the ambient air, water vapor in the air will condense into water droplets. After setting the insulation pipe 2, the surface temperature of the duct is greater than or equal to the dew point temperature, thus preventing condensation.

[0025] Protective components are installed on both sides of the duct body 1. The protective components include an upper support 3 and a lower support 4. Multiple reinforcing ribs 5 are vertically connected between the upper support 3 and the lower support 4. Steel connecting rods 6 are fixedly installed between the multiple vertically arranged reinforcing ribs 5. A connecting plate 7 is fixedly installed between the two sets of upper supports 3. The bottom sides of the connecting plate 7 are connected to the top wall of the insulation pipe 2 through connecting parts. By setting the upper support 3 and the lower support 4, protective support is formed on the outer wall of the duct body 1, which can enhance the rigidity of the duct body 1 itself. During transportation, it is avoided that the duct body 1 will be directly damaged or deformed due to collision. When disassembling later, the upper support 3 and the lower support 4 can be removed using a suitable wrench.

[0026] Furthermore, during transportation, multi-layered stacked ducts are prone to deformation of the lower ducts due to the weight of the upper layer. The support frame can transfer the upper load to the floor of the carriage through the support, avoiding direct pressure on the ducts and absorbing high-frequency vibrations during transportation, thus reducing the vibration amplitude on the surface of the duct body 1. The combined structure of the upper support 3, the lower support 4, and the reinforcing rib 5, through multiple mechanisms of "rigid support + load distribution + vibration control", fundamentally solves the problem of deformation and damage during duct transportation, and is especially suitable for large-size, thin-walled, or composite material duct bodies 1.

[0027] The reinforced components include a fixing plate 11, which is fixedly installed on the bottom side of the inner wall of the insulation pipe 2 and connected by bolts. A support plate 16 is fixedly installed at the top center of the fixing plate 11. A ventilation slot 14 is opened in the middle of the support plate 16. The support plate 16 serves as a vertical support structure. By opening the ventilation slot 14, the blockage of airflow inside the pipe is reduced. That is, the gas flow between the duct body 1 and the insulation pipe 2 can flow directly through the ventilation slot 14.

[0028] Multiple support columns 15 are fixedly connected to both sides of the support plate 16. The ends of the multiple support columns 15 are fitted into the two inner side walls of the insulation pipe 2. The top of the support column 15 is fixedly connected to the support frame 13.

[0029] Multiple reinforcing blocks 12 are fixedly connected to both ends of the support frame 13. The top wall of the support frame 13 is fixed to the inner bottom wall of the insulation pipe 2 to enhance the rigidity and support of the insulation pipe 2.

[0030] The connecting component includes a steel block 8, which is set on the top wall of the insulation pipe 2. Both sides of the top of the steel block 8 are fixedly connected to the docking seat 9. The top of the docking seat 9 is connected to the fixing rod 10. The fixing rod 10 passes through the air duct body 1 and connects with the connecting plate 7.

[0031] A sealing gasket is pre-installed at the intersection of the fixing rod 10 and the duct body 1. Since the fixing rod 10 is connected to the top of the internal insulation pipe 2, two holes will appear on the top wall of the duct body 1. By using the sealing gasket to connect the fixing rod 10 and the duct body 1, the sealing of the inner ring of the hole is increased, preventing the airflow inside the duct body 1 from flowing outward in the later stage, and increasing the overall sealing performance.

[0032] By setting a protective structure consisting of an upper support and a lower support on the outer wall of the duct body, and setting several reinforcing ribs and connecting rods between the upper support and the lower support, the side wall of the duct body is protected, which can greatly reduce the deformation of the duct body caused by vehicle vibration during transportation.

[0033] By adding an insulation pipe 2 inside the duct body 1, water droplets can be prevented from condensing due to water vapor in the air when cold air blows inside the duct, thus preventing condensation on the outer wall of the duct. Furthermore, a reinforcing component is added inside the insulation pipe to further improve the rigid support effect inside the insulation pipe.
