Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration machinery, and more specifically, it relates to a refrigeration unit with a quick-release pipe joint structure. Background Art

[0002] A refrigeration unit with a quick-release pipe joint structure is a device specifically used to provide a cooling effect. Its characteristic lies in the quick disassembly and installation of pipe connections. Refrigeration units with quick-release pipe joint structures are widely used in equipment such as air conditioners, refrigerators, cold storages, and automotive air conditioners, providing a convenient and comfortable environment for people's lives and work. With the continuous development of technology, the design and functions of refrigeration units are also constantly improved and innovated to meet higher performance and environmental protection requirements.

[0003] In the existing technology, firstly, some devices cannot achieve quick and firm snap-fitting fixation, which will result in more time and effort required to complete the connection during the operation process, reducing work efficiency. The stability of the connection will be affected, possibly leading to loosening or leakage at the connection point, increasing maintenance costs and safety risks. Secondly, in cases where precise control or a large force is required, this may lead to inaccurate operation or damage to the equipment. The movement range of the snap-fitting components will not be restricted, possibly resulting in an unstable position of the snap-fitting rod during the operation process, affecting the accuracy of the connection. Finally, the connection of some devices is unstable and prone to loosening. Summary of the Utility Model
