Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a stainless steel air duct with high strength. Background Art

[0002] Stainless steel air ducts can be divided into two types: round and rectangular. Finished air ducts of various shapes, specifications and models and plates can be produced according to the different requirements of the project site. The main materials of stainless steel air ducts are: SUS304, 316, 303, etc. The surface properties of stainless steel air ducts mainly include 8K mirror panels, colored stainless steel plates, stainless steel frosted plates, stainless steel brushed plates, stainless steel patterned plates, stainless steel etched plates, titanium, snowflake sand, 2B plates, BA plates and industrial medium and thick plates. When assembling and docking the existing air ducts, because the air ducts are basically suspended, docking is difficult, and the air ducts are large in size and have a certain length tolerance. When docking, the length cannot be adjusted, so a high-strength stainless steel air duct is urgently needed. Utility Model Content

[0003] 1. Technical Problems to be Solved by the Utility Model

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-strength stainless steel air duct, which has the advantages of freely adjusting the length of the air duct and reducing the difficulty of installation, thereby solving the problem that the length cannot be adjusted and precise docking is difficult due to tolerances in the production of air ducts.

[0005] 2. Technical solution

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A high-strength stainless steel air duct comprises a tube body and an adjusting piece installed in the middle of the tube body, and the tube body is divided into two.

[0008] As an optimization, the adjusting member includes fixing rings respectively installed on opposite surfaces of the two tube bodies, and the fixing rings are two semicircular ring pieces that are locked and fixed and a retractable corrugated soft sleeve fixed between the fixing rings.

[0009] As an optimization, sliding holes and adjusting columns are arranged on opposite sides of the two tube bodies.

[0010] As an optimization, the two tube bodies can be fixed by a plurality of adjustment columns.

[0011] As an optimization, the sliding hole and the adjustment column radius correspond to each other to achieve a sliding connection.

[0012] As an optimization, a connecting ring that is directly connected to other air ducts on opposite sides of the two pipe bodies.

[0013] As an optimization, the sliding distance of the adjustment column is half of the depth of the sliding hole. When the air ducts are docked, the docking is first achieved through the connecting rings on the opposite sides of the two tube bodies. At that time, because the air duct docking requires precise control of the tube body length, when docking, the tube body is dragged out in a single direction so that the adjustment column on one side of the tube body slides out of the sliding hole, thereby increasing the overall air duct length. The air duct length can also be reduced to adapt to different situations, thereby increasing the adaptability and freedom of air duct docking. When adjusting the length, the two slidingly connected tube bodies 1 are connected by the corrugated soft sleeve 22 between the adjusting parts 2. At that time, after the length is adjusted, the corrugated soft sleeve 22 can be expanded and contracted to seal the moving part of the tube body 1 to ensure air tightness.

[0014] As an optimization, a sealing gasket is embedded in the outside of the connecting ring, and the gasket is made of rubber material, and the sealing gaskets are pressed in pairs to ensure the sealing performance.

[0015] As an optimization, the inside of the pipe body includes an insulation layer made of polystyrene material wrapped on the air duct and cross-staggered reinforcement ribs fixed in the insulation layer, and the reinforcement ribs are used to improve the strength of the air duct. The above insulation layer can achieve that the high-temperature gas or low-temperature gas in the pipe can hinder the heat exchange between the inside and outside of the air duct to a certain extent, so that the air duct layout space is affected by the temperature of the gas in the air duct, and the cross-structure of the reinforcement ribs increases the strength of the outer layer of the air duct, so that the air duct will not be dented or deformed due to collision or falling during transportation.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the utility model are: the utility model is a high-strength stainless steel air duct, which is provided with sliding holes and adjusting columns on the opposite surfaces of two tube bodies. When docking with other air ducts, the tube body is slid on one side to allow the adjusting column to slide outward from the sliding hole or slide inward to increase or retract the length of the air duct, so as to adjust to the length suitable for docking, and a corrugated soft sleeve is fixed between the two groups of tube bodies to ensure sealing while adapting to the length adjustment of the two tube bodies. In summary, the tube body with adjustable length is used to reduce the installation difficulty when docking the air ducts. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, the adjusting member 2 includes fixing rings 21 respectively mounted on opposite surfaces of the two tube bodies 1 , and the fixing rings 21 are two semicircular ring pieces that are locked and fixed, and a retractable corrugated soft sleeve 22 is fixed between the fixing rings 21 .

[0028] In this embodiment, the sliding holes 131 and the adjusting posts 132 are disposed on opposite sides of the two tube bodies 1 .

[0029] In this embodiment, the two tube bodies 1 can be fixed by a plurality of adjustment columns 132 .

[0030] In this embodiment, the sliding hole 131 and the adjusting column 132 have corresponding radii to achieve sliding connection.

[0031] In this embodiment, a connecting ring 10 is directly connected to the opposite sides of the two pipe bodies 1 and is connected to other air ducts.

[0032] In this embodiment, the sliding distance of the adjusting column 132 is half of the depth of the sliding hole 131 .

[0033] When the air ducts are connected, the connection rings 10 on the opposite sides of the two pipe bodies 1 are first used to connect the two pipe bodies 1. At that time, because the length of the pipe body 1 needs to be precisely controlled during the connection of the air ducts, the pipe body 1 is dragged out in a single direction during the connection, so that the adjustment column 132 on one side of the pipe body 1 slides out from the sliding hole 131, thereby increasing the overall length of the air duct. The length of the air duct can also be reduced to adapt to different situations, thereby increasing the adaptability and freedom of the air duct connection.

[0034] When adjusting the length, the two slidingly connected tube bodies 1 are connected by the bellows soft sleeve 22 between the adjusting parts 2. After the length is adjusted, the bellows soft sleeve 22 can be extended and retracted to seal the movable part of the tube body 1 to ensure air tightness.

[0035] Embodiment 2

[0038] The above-mentioned insulation layer 4 can be used to hinder the heat exchange between the inside and outside of the duct by the high-temperature gas or low-temperature gas in the duct to a certain extent, so that the duct layout space is affected by the gas temperature in the duct, and the cross structure adopted by the reinforcing ribs 3 increases the strength of the outer layer of the duct, so that the duct will not be dented or deformed due to collision or falling during transportation.
