Description

Technical Field

[0001] The utility model relates to the field of air conditioner installation, and more specifically to a hose-type connecting device for an indoor unit of an air conditioner and an outdoor unit of an air conditioner. Background Art

[0002] When connecting the indoor and outdoor units of the air conditioner, pipe docking installation is required, and in order to facilitate adjustment and control, hoses are mostly used for combined positioning.

[0003] However, in the existing hose connection device structure, most of them simply use a clamp to clamp and position the hose. In this way, the clamp and the hose are installed separately, which is easy to fall off and misaligned, resulting in insufficient clamping stability and leakage. In addition, it cannot effectively protect after installation and positioning, resulting in poor safety of the clamp positioning position. The hose is also easy to collapse and reduce the inner diameter, affecting the passability, which needs to be improved. Utility Model Content

The fixed pipe on the surface of the outer shell is connected with the hose for combined installation, and the positioning buckle connection clamp at the end can be used to ensure the strength of the integrated structure while pressing and positioning in an annular manner to avoid falling off and dislocation. At the same time, the protective tube is installed through the connecting ring, which can be connected for protection after installation to ensure safety. This can greatly improve the convenience and stability of use and ensure the safety and efficiency of the connection.
