Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a quick connector. Background Technology
[0002] Quick couplings are devices used for connecting automotive parts. Their main function is to enable the rapid connection and disconnection of liquid and gas transmission lines in a car. In a car's cooling system, coolant needs to circulate between different components. Quick couplings allow water pipes connecting components such as the radiator and engine to be easily connected during installation and maintenance without complicated tools. Compared to traditional connection methods, this method greatly saves time and labor costs. Quick couplings have a wide range of applications in automobiles, and their importance lies in their efficiency and convenience. In the automotive transmission system, hydraulic lines are connected via quick couplings.
[0003] A search revealed Chinese Patent Publication No. CN219198482U, which discloses a quick connector. The quick connector includes a hollow connector body with both ends connected. The connector body includes a connecting portion and a rotating portion rotatably connected to one end of the connecting portion. The end of the connecting portion facing the rotating portion mates with the rotating portion to form a first interface for connecting a cooling water conduit. The inner wall of the rotating portion has a limiting groove for inserting an adapter. This application facilitates changing the orientation of the cooling water conduit connected to the quick connector according to actual conditions. However, while this device can change the orientation of the cooling water conduit connected to the quick connector, it cannot quickly connect the connector, leading to increased production time and reduced production efficiency. Utility Model Content
