Description

Technical Field

[0001] The utility model relates to the field of air ducts, in particular to a spliced air duct structure. Background Technique

[0002] The air duct is a key component for transporting air in ventilation and air conditioning systems. Its main function is to introduce fresh air into the room or exhaust the indoor air. The materials of the air duct usually include galvanized steel sheets, stainless steel, plastics or aluminum materials, which have good corrosion resistance and strength. According to the installation position and use, the air duct can be divided into different shapes such as circular, square and rectangular. When designing the air duct, factors such as air flow, wind speed and noise need to be considered to ensure the efficient operation of the system.

[0003] A reasonable air duct layout can reduce air resistance, improve energy efficiency and optimize indoor air quality. In addition, the insulation and sealing performance of the air duct are also crucial to prevent energy loss and the generation of condensate. In practical applications, the cleaning and maintenance of the air duct system are also important links that cannot be ignored to avoid the accumulation of dust and pollutants and ensure the normal operation of the ventilation system. The air duct plays an important role in the ventilation, air conditioning and air purification of modern buildings, and its design and maintenance directly affect the comfort and health of the indoor environment.

[0030] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a spliced air duct structure, including a duct 1, which is a path for conveying air. Flanges 2 are fixedly connected to both the left and right sides of the duct 1. The flanges 2 are for facilitating the connection of the ducts 1 to each other. A plurality of outer shells 3 are fixedly connected to the inside of the left flange 2. A fixing plate 4 is fixedly connected to the inner wall of the outer shell 3. A spring 5 is fixedly connected to the left side of the fixing plate 4. The left end of the spring 5 is fixedly connected to a baffle 6. A pressure rod 7 is fixedly connected to the inside of the baffle 6. The right end of the pressure rod 7 is fixedly connected to a connecting block 8. Four pull rods 9 are rotatably connected to the outside of the connecting block 8. A stop block 10 is rotatably connected to the outside of the pull rod 9. An extension section 11 is fixedly connected to the right end of the duct 1. The outer shell 3 is used for connecting and protecting the internal parts. The fixing plate 4 is used for fixing and supporting the fixing plate 4. The pressure rod 7 is for facilitating manual pressing to drive the baffle 6 to compress the spring 5. The baffle 6 bears the pressure from the spring 5 and drives the pressure rod 7 to move synchronously. The spring 5 is used to push the baffle 6 and drive the pressure rod 7 to reset. The connecting block 8 is for simultaneously driving the four pull rods 9 to deflect. The pull rod 9 is for pulling the stop block 10 to move. The stop block 10 is used to block the outlet of the flange 2 to prevent the duct 1 from detaching. The extension section 11 is for inserting into the inside of another duct 1. Among them, the diameter of the extension section 11 is smaller than that of the duct 1. A sealing component is installed inside the duct 1. The sealing component is used to seal the spliced ducts 1 to prevent air leakage. The outside of the pressure rod 7 is slidably connected inside the outer shell 3. The outside of the pressure rod 7 is slidably connected inside the fixing plate 4. The pressure rod 7 can only move left and right under the limitation of the outer shell 3 and the fixing plate 4 and will not move randomly or wobble. The outside of the baffle 6 is slidably connected to the inner wall of the outer shell 3. The baffle 6 can only move left and right under the limitation of the outer shell 3 to avoid random movement. The spring 5 is sleeved outside the pressure rod 7 to keep the spring 5 stable. The outside of the stop block 10 is slidably connected inside the outer shell 3. The stop block 10 is in contact with the left side of the right flange 2. The pull rod 9 blocks the flange 2 on another duct 1 to fix it. The outside of the outer shell 3 is slidably connected inside the right flange 2. The spring 5 is sleeved inside the outer shell 3 to keep the spring 5 stable.

[0031] Refer to Figure 1 - Figure 3, the sealing assembly includes two support frames 12, a wire reel 14 and a sealing gasket 17. The bottom of the support frame 12 is fixedly connected to the top of the pipeline 1. A worm 13 is rotatably connected between the tops of the two support frames 12. The bottom of the wire reel 14 is rotatably connected to the top of the pipeline 1. A worm gear 15 is fixedly connected to the top of the wire reel 14. The worm gear 15 meshes with the worm 13. A rope 16 is fixedly connected to the outside of the wire reel 14. The outside of the sealing gasket 17 is fixedly connected to the inside of the pipeline 1. The support frame 12 is used to support and connect the worm 13. The meshing between the worm 13 and the worm gear 15 is to drive the wire reel 14 to rotate. The wire reel 14 is used to wind the rope 16 and tighten the rope 16. The rope 16 is arranged inside the pipeline 1 to tighten the sealing gasket 17. The sealing gasket 17 is used for sealing to prevent air leakage at the interface. The outside of the rope 16 is arranged inside the pipeline 1, and the outside of the sealing gasket 17 is sleeved inside the rope 16. The sealing gasket 17 is tightened by the rope 16 and abuts against the extension joint 11 to achieve sealing.

[0032] Working principle: When installing this device, first press the pressure rod 7. Under the connection of the fixed plate 4, the baffle 6 is driven to compress the spring 5. At the same time, the connecting block 8 pulls the pull rod 9 to retract the stop block 10 into the housing 3. Then align the extension joint 11 on another pipeline 1 with the left end of the pipeline 1 and insert it. Then release the pressure rod 7. At this time, the spring 5 pushes the baffle 6 to drive the pressure rod 7 to pull the connecting block 8, so that the pull rod 9 pushes the stop block 10 out and expands, blocking the left side of the right flange 2 on another pipeline 1 to achieve splicing and fixing. After splicing, then rotate the worm 13 to drive the worm gear 15 to make the wire reel 14 rotate, pull the rope 16, tighten the rope 16, and at the same time tighten the sealing gasket 17, so that the sealing gasket 17 tightly adheres to the outer wall of the extension joint 11 to achieve sealing and avoid air leakage affecting the conveying efficiency.
