Description

Technical Field

[0001] The utility model belongs to the technical field of integrated flange air ducts, and particularly relates to an integrated flange air duct. Background Art

[0002] The integrated flange duct, also known as the common plate flange duct or flangeless duct, is a modern duct connection method. Its main feature is that the duct and the flange are formed in one piece, and no additional flange connectors are required, thereby simplifying the processing and installation process. This type of duct has the advantages of easy processing, material saving, and good sealing.

[0003] A Chinese patent with announcement number "CN208417801U" discloses a rectangular common plate flange air duct, including an air duct shell, which is fixedly placed on an air duct hanger, and the air duct hanger is suspended by a galvanized wire hanger, and an expansion bolt is arranged at the top of the galvanized wire hanger. The top of the air duct shell is provided with a first reinforcement member, a second reinforcement member and a third reinforcement member from left to right in sequence, and the air duct shell includes a horizontal side plate and a vertical side plate, and a horizontal flange plate is arranged at the end of the horizontal side plate.

[0004] However, this flange air duct still has some shortcomings. Because the inside of the flange air duct is ventilated for a long time, there is some dust and pollutants in the circulating air. These dust and pollutants will be adsorbed on the inner wall of the flange air duct. After a long period of accumulation, it will affect the normal use of the flange air duct. At the same time, because the flange air duct is not easy to disassemble and assemble, it is not conducive to the user to clean the dust and pollutants later. Utility Model Content

When in use, the position of the mounting plate 11 is fixed by a positioning piece matching the positioning hole 12. When the wind passes through the inner side of the flange air duct body 1, its filter plate 13 can effectively filter the dust and pollutants circulating in the wind, thereby preventing a large amount of dust and pollutants from accumulating on the inner wall of the flange air duct body 1. Because the filter plate 13 is installed in the connecting frame 6, when it is necessary to deal with the dust, the first bolt 10 is screwed out of the first screw hole 9, and then the block 7 is pulled out of the slot 5, and the connecting frame 6 will be disassembled individually, which is also beneficial for the user to uniformly clean the dust and pollutants blocked in the connecting frame 6.

[0026] refer to Figures 1 to 4A fixing block 15 is fixedly connected to one side of the filter plate 13, and the rear side of the fixing block 15 is in contact with the inner wall of the connecting frame 6.

A handle 18 is fixedly connected to one side of the filter plate 13 and is connected to the inner wall of the connecting frame 6. The shape of the handle 18 is concave, and the shape of the corner of the handle 18 is arc-shaped. Due to the existence of the second bolt 17, the screwing of the second bolt 17 can effectively fix the position of the filter plate 13, thereby preventing the filter plate 13 from being displaced. The handle 18 can provide the user with a gripping point. When the filter plate 13 needs to be removed, the second bolt 17 is screwed out of the second screw hole 16, and then the filter plate 13 is pulled out along the slide groove 14. Therefore, the purpose of individually disassembling and assembling the filter plate 13 can be achieved, and it is also convenient for the user to maintain or replace the filter plate 13 at a later time.

[0031] Principle and advantages of use: When in use, the position of the mounting plate 11 is fixed by a positioning piece matching the positioning hole 12. When wind passes through the inner side of the flange duct body 1, the filter plate 13 can effectively filter the dust and pollutants circulating in the wind, thereby preventing a large amount of dust and pollutants from accumulating on the inner wall of the flange duct body 1. Because the filter plate 13 is installed in the connecting frame 6, when it is necessary to deal with the dust, the first bolt 10 is screwed out of the first screw hole 9, and then the card block 7 is pulled out of the card slot 5, and the connecting frame 6 will be disassembled individually, which is also conducive to the user to uniformly clean the dust and pollutants blocked in the connecting frame 6. Due to the existence of the second bolt 17, the screwing of the second bolt 17 can effectively fix the position of the filter plate 13, thereby preventing the filter plate 13 from being displaced. The handle 18 can provide the user with a gripping point. When the filter plate 13 needs to be disassembled, the second bolt 17 is screwed out of the first screw hole 9, and then the card block 7 is pulled out of the card slot 5. The connecting frame 6 will be disassembled individually. At the same time, it is also convenient for the user to clean the dust and pollutants blocked in the connecting frame 6 in a unified manner. Due to the existence of the second bolt 17, the screwing of the second bolt 17 can effectively fix the position of the filter plate 13, thereby preventing the filter plate 13 from being displaced. The handle 18 can provide the user with a gripping point. The second screw hole 16 is pulled out, and then the filter plate 13 is pulled out along the slide groove 14, so that the purpose of individually disassembling and assembling the filter plate 13 can be achieved, and it is also convenient for the user to maintain or replace the filter plate 13 later. Due to the presence of the rubber pad 20, the rubber pad 20 is a rubber product with good anti-slip ability and rubber shock absorption ability, thereby effectively improving the stability of the fixed position of the mounting plate 11. Due to the presence of the sealing ring 8, the sealing ring 8 can effectively seal the connection point between the connecting frame 6 and the flange duct body 1, thereby avoiding the situation that air leakage occurs at the connection point between the two, thereby effectively improving the overall sealing of the flange duct body 1. Due to the opening of the strip opening 2, the user can directly view the inner side of the flange duct body 1 through the transparent glass 3 without opening the flange duct body 1. If there is a foreign object on the inner side of the flange duct body 1, the staff can also know it in time and then deal with it.
