Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning parts, and in particular to a flexible connecting device for air-conditioning pipes. Background Art

[0002] Air conditioning ducts are essential accessories in air conditioning work, and in actual use, air conditioning ducts need to be butt-jointed and assembled between pipes.

[0003] For example, Chinese patent application CN220186104U discloses an air-conditioning duct, which records: by providing a duct body, a connecting ring, a locking block, a guide surface, a reset piece and a connecting hole, during the assembly of the air-conditioning duct, the staff only needs to press two adjacent duct bodies in a direction toward each other, which simplifies the steps for the staff to assemble the air-conditioning duct, thereby reducing the occurrence of complicated operating steps when the staff assembles the air-conditioning duct.

[0004] During the installation process of the above-mentioned air-conditioning ducts, the ducts are butt-jointed and assembled. The air-conditioning ducts that are butt-jointed and assembled between the ducts will generate vibration and noise in actual use, causing discomfort to the users. In addition, the two ducts cannot be axially adjusted, and it is necessary to measure the distance between the two ducts in advance to select ducts of appropriate lengths, which brings difficulties to the installation of the ducts on site. Therefore, the butt-jointed installation between the above-mentioned two ducts cannot adapt to different installation environments and space limitations, resulting in extremely difficult installation, difficulties in maintenance and replacement of parts, and the fixed duct layout limits the operating space, making duct maintenance and repair work more complicated and difficult.
