Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a quick air duct support frame. Background Art

[0002] Air ducts are mainly used for gas transportation. Air ducts are suitable for the installation of air conditioning and ventilation engineering in industries and various buildings. They are widely used in food processing, machinery manufacturing, pharmaceutical products, electronics industry, shopping centers, cotton textiles, sports and entertainment cultural venues, hotels, supermarkets, office buildings, government agencies, small villas, family homes and aerospace manufacturing.

[0003] The existing traditional duct support frame consists of two support rods that directly penetrate the two ends of the duct and are fixed by nuts to support the duct and prevent the inner wall of the duct from collapsing. However, since the support frame is mostly fixed, the fixed frame cannot be folded, so it is large in size and occupies a large space during transportation, which is inconvenient to use. At the same time, the size of the above-mentioned duct support frame is mostly fixed, so the duct support frame cannot be adjusted, and thus cannot be used for ducts of different lengths, resulting in reduced practicality and inconvenience for promotion. In view of this, we introduce a duct quick support frame. Summary of the invention

[0031] The fixing bracket A1, the fixing bracket B3, the fixing bracket C5 and the fixing bracket D4 are provided with an adjustment mechanism inside, and the lower pressure column 11 of the adjustment mechanism drives the spring 15 to be compressed so that the length of the fixing bracket A1, the fixing bracket B3, the fixing bracket C5 and the fixing bracket D4 can be adjusted.

[0032] The fixed bracket B3 and the fixed bracket D4 are respectively connected to a plug-in block 13 on one side, and the plug-in block 13 is welded to the fixed bracket B3 and the fixed bracket D4. The plug-in block 13 is inserted into the interior of the fixed bracket A1 and the fixed bracket C5. The interior of the plug-in block 13 is provided with a fixed cavity 14, and the fixed cavity 14 and the plug-in block 13 are integrally formed.
