[0002] HVAC is an integral part of a building. It includes three aspects: heating, ventilation, and air conditioning. When transporting gas, corresponding HVAC pipes are generally required for transportation. Since HVAC pipes are generally of a specified length during production, and the installation position is relatively uncertain, corresponding connecting devices are generally required to connect multiple HVAC pipes to facilitate long-distance transportation. Most of the existing HVAC pipe connecting devices use a long tube, through which the ends of the two HVAC pipes to be connected are sealed and wrapped, and most of them are welded or fixed. When a component is damaged, it is not convenient to disassemble. When the HVAC pipe enters, the width of the long tube cannot adapt to the size of most HVAC pipes, and the long tube is wider than the HVAC pipe, that is, the HVAC pipe will shake in the long tube, and there is a defect that the pipe cannot be maintained stable.
