Which two parts of the Quick Coupling jointly realize the connection function between the hose and the equipment?

As an efficient and convenient fluid transmission connection device, the core function of the Quick Coupling is to realize the fast, safe and reliable connection and disconnection between the hose and the equipment through its unique structural design. The realization of this function mainly depends on the two core components of the Quick Coupling: the connector body (socket or female end) and the connector plug (male end).
The inner cavity of the connector body is usually equipped with precision sealing elements, such as O-rings, V-rings or specially customized sealing rings. These sealing elements are made of highly elastic and wear-resistant materials, which can fit tightly when the connector plug is inserted to effectively prevent fluid leakage. At the same time, the material and size of the sealing elements are strictly calculated and tested to ensure good sealing performance under various working conditions.
In order to ensure the firmness of the connection, a complex locking mechanism is usually designed in the connector body. These mechanisms may include spring-loaded steel balls, sleeves, claws, etc., which can automatically lock when the connector plug is inserted to prevent it from accidentally falling off. The design of the locking mechanism not only takes into account the stability of the connection, but also takes into account the convenience of operation, allowing users to easily connect and disconnect operations. In some specific application scenarios, a one-way valve may also be installed in the connector body. When the connector body is separated from the connector plug, the one-way valve will automatically close to prevent fluid backflow or leakage, thereby protecting the system from damage.
As the movable end of the Quick Coupling, the connector plug is also designed with attention to the tightness of the connection, the convenience of operation and durability. The shape and size of the connector plug usually match the inner cavity of the connector body precisely to ensure a tight fit during the insertion process. This fit not only helps to enhance the stability of the connection, but also reduces the risk of fluid leakage.
The connector plug may be designed with structures that cooperate with the locking mechanism in the connector body, such as grooves, flanges or specially shaped heads. These structures can interact with the locking mechanism during insertion to achieve automatic locking. At the same time, these designs also take into account the convenience of user operation, making the connection and disconnection process easier. In some cases, the connector plug may also be equipped with additional sealing elements, such as O-rings or sealing rings. These sealing elements can further enhance the sealing performance of the connection and ensure that a good sealing effect can be maintained under various working conditions.
When it is necessary to connect the hose and the equipment, the user only needs to align the connector plug with the connector body and gently insert it. During the insertion process, the connector plug pushes the locking mechanism in the connector body and automatically locks it. At the same time, the sealing elements between the connector plug and the connector body are in close contact and form a sealed connection. In this way, a quick and effective connection is achieved between the hose and the device.
When it is necessary to disconnect, the user only needs to press the release button on the connector body (if designed) or use other unlocking methods (such as rotation, sliding, etc.) to unlock the locking mechanism. Then, the user can gently pull out the connector plug to disconnect. During the disconnection process, if a one-way valve is installed in the connector body, the one-way valve will automatically close to prevent fluid leakage.
