The air duct single body is provided with the indentation groove, and the indentation groove extends along the direction from the front end opening to the rear end opening of the air duct single body, namely, the indentation groove has the same flow direction as the air in the air duct, and plays roles of diversion and shock absorption, so that the stability of the air duct can be enhanced.
Description
Technical Field
The utility model relates to an air duct structure.
Background
The ventilating duct is a ventilating metal duct of industrial and civil buildings, and is a municipal infrastructure for reducing the concentration of harmful gases in order to circulate air. The ventilating duct is divided into materials, generally comprising: steel plate air pipes (common steel plates), galvanized plate (white iron) air pipes, stainless steel ventilation pipes and the like.
To increase the wind resistance of the ductwork, it is generally achieved by increasing the thickness of the sheet material from which the ductwork is made, but this method is relatively costly.
Disclosure of Invention
The utility model aims to provide an air duct structure, which comprises a plurality of air duct monomers connected end to end in sequence, wherein each air duct monomer comprises a front port and a rear port; the air pipe monomer is provided with a plurality of indentation grooves extending along the direction from the front port to the rear port; the indentation grooves are uniformly distributed at intervals.
The air duct single body is provided with the indentation groove, and the indentation groove extends along the direction from the front end opening to the rear end opening of the air duct single body, namely, the indentation groove has the same flow direction as the air in the air duct, and plays roles of diversion and shock absorption, so that the stability of the air duct can be enhanced.
When the method is implemented, the indentation groove is pressed on the basis of the original plate, the plate with increased thickness is not required to be purchased, and the cost is saved.

Detailed Description
The present application is further described with reference to the following drawings:
referring to fig. 1-7, an air duct structure comprises a plurality of air duct monomers 1 which are connected end to end in sequence, wherein each air duct monomer 1 comprises a front port 11 and a rear port 12; the air duct unit 1 is provided with a plurality of indentation grooves 13 extending along the direction from the front port 11 to the rear port 12; the indentation grooves 13 are uniformly spaced apart.
The utility model discloses a be equipped with indentation groove 13 on tuber pipe monomer 1 of this technical scheme, indentation groove 13 extends along the direction of the preceding port 11 of tuber pipe monomer 1 toward back port 12, promptly with intraductal gas flow direction the same, plays water conservancy diversion, absorbing effect, and then can strengthen the stability of tuber pipe.
In the implementation, the indentation groove 13 is pressed on the basis of the original plate, the plate with increased thickness is not required to be purchased, and the cost is saved.
The cross section of the indentation groove 13 is U-shaped. The U-shaped indentation groove 13 has smooth flow guiding and is not easy to stick to the mold in the pressing process.
The front port 11 and the rear port 12 of the air duct monomer 1 are respectively provided with a connecting frame 2, and specifically, the connecting frames 2 are arranged around the periphery of the port of the air duct monomer 1. The connecting frame 2 is provided with a connecting hole 21; the connecting frames 2 on the rear ports 12 of the air duct monomers 1 are abutted against the connecting frames 2 on the front ports 11 of the adjacent air duct monomers 1, connecting pieces are arranged in the connecting holes 21 of the two connecting frames 2 in a penetrating mode to be fixedly connected, and the elastic gaskets 4 are arranged between the two connecting frames 2 in a clamping mode, so that the tightness between the connecting frames 2 can be improved, and air leakage is prevented.
The connecting piece comprises a bolt 3, and a locking nut 31 is arranged at the tail end of the bolt 3.
The air duct monomers 1 are spliced through the connecting frame 2 and are matched and fixed through the bolts 3 and the locking nuts 31, so that the operation is simple and the implementation is easy.
The connecting frame 2 is provided with a ring groove 22 into which the end part of the air supply pipe monomer 1 is inserted. Glue is filled in the ring groove 22 to fix the air duct unit 1 and the connecting frame 2.
The ring groove 22 provides a connecting space for the air duct single body 1, and can ensure the stability and the tightness of connection by filling glue for bonding. And compared with the connection mode of folding and winding the plate on the frame body, the material is saved.
The above-mentioned preferred embodiments should be regarded as illustrative examples of embodiments of the present application, and all such technical deductions, substitutions, improvements and the like which are made on the basis of the embodiments of the present application, are considered to be within the scope of protection of the present patent.
