An air duct butt joint device for ventilation construction

Abstract

The invention discloses an air duct butt joint device for ventilation construction, relates to the technical field of air duct butt joint devices, and solves the problem that the air duct has a high integrity after the existing air duct butt joint, so that after the air duct is installed, the air duct It is impossible to disassemble a single section separately, which is a troublesome problem when disassembling and maintaining a certain section of air duct. An air duct jointing device for ventilation construction, comprising a joint air duct; the joint air duct is plugged outside the main air duct. The device docks the two main air ducts by plugging in one end of the main air duct outside the main air duct, and the butt air duct of the device can be independently expanded and contracted, thereby completing the disassembly of the main air duct inside the docked air duct at one end. After the air duct system is installed, the single-section main air duct can be disassembled independently, so as to facilitate the repair and maintenance of the air duct system.

Description

technical field [0001] The invention belongs to the technical field of air duct jointing devices, and more specifically relates to an air duct jointing device for ventilation construction. Background technique [0002] Ventilation engineering is a general term for air supply, exhaust, dust removal, pneumatic conveying, and smoke prevention and exhaust system engineering. At present, multiple air ducts are used in ventilation engineering to connect to realize the air supply function of the fan, so that the interior of the building can be ventilated. , dust removal and cooling, etc. [0003] For example, in the patent with the application number: CN201611027655.3, a device for realizing the docking / separation of the temperature regulating unit and the launching tube is disclosed. The purpose is to provide an air duct sealing docking device with simple structure, large ventilation volume, strong environmental adaptability, and quick docking and separation of the launch tube an...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides an air duct docking device for ventilation construction, to solve the problem of connecting the two ends of the air duct with a fixing frame through rivets, and fixing the two ends with screws. The frame is fixed to realize the docking of the air duct. The integrity of the air duct in this docking method is high, so that after the installation of the air duct is completed, the air duct cannot be disassembled in a single section. When disassembling and maintaining a certain section of the air duct It is troublesome, the steps are cumbersome, and the practicability is not high
