[0016] Fig. 2 It is the connecting locking structure schematic view of the utility model. DETAILED DESCRIPTION

[0017] As Figs. 1-2As shown, a quick-connect connector includes a housing 4 and a movable component 1, which is a linearly movable assembly. The movable component 1 and the housing 4 form a gas passage for the medium to pass through. The gas passage has an inlet connector 2 and an outlet connector 3 at both ends, which is the flow channel for the test gas. In this application, the movable component 1 is designed to control the cutting off or opening and closing of the gas passage. Only misalignment or other coordination is needed to meet the requirements. This is an existing basic design, and it will not be elaborated or limited further here. The inlet connector 2 is located on the outer casing 4, and the outlet connector 3 is located at the outermost end of the movable part 1. The outer casing 4 has an opening at the outlet connector 3 for the movable part 1 to extend out. The outlet connector 3 and the movable part 1 are axially linked. The outlet connector 3 includes several threaded teeth 5 evenly arranged around the circumference and a sealing ring 12 fitted at the root. The opening has a groove near the inner edge to at least partially accommodate the sealing ring 12. The threaded teeth 5 have a radially outward expanding or inward contracting state. The outer casing 4 has an air hole 9, a thumb valve, or a pressure rod 8 for driving the movable part 1. The outlet connector 3 is mainly composed of threaded teeth 5 and a sealing ring 12. The movable part 1 can push out or push out the threaded teeth 5 axially in the outer casing 4, so that the sealing ring 12 cannot fill the gap, which is beneficial for venting residual gas in the connector. The design of the threaded teeth 5 allows the fluid to exert an external force when passing through, i.e., expansion locking, which is beneficial for shortening the test time and strengthening the connection tightness. This design allows the moving part 1 to seal or release air during operation, resulting in smooth and efficient action; the design is ingenious and reasonable. Simultaneously, the expansion-type locking minimizes damage to the threaded teeth, and an expansion groove is also incorporated in this embodiment. An expansion groove is provided on the inner wall of the threaded claw 5, and the groove opening is directly connected to the air passage. The expansion groove design allows the gas to exert a direct radial force on the threaded claw 5, aiding in maintaining the locking state. The sealing ring 12 is simple and reliable in design, easy to replace, and has low maintenance costs; different materials can be used depending on the fluid. The inlet connector 2 is located on the radial side wall of the outer shell 4 and is integrally connected to the outer shell 4. This is a conventional design, using a threaded connection, which ensures structural strength and facilitates production and use.

[0018] The outlet connector 3 has a positioning groove 6 at the root of the thread claw 5 for installing the sealing ring 12, which strengthens the installation and positioning of the sealing ring 12. The groove design is to avoid excessive compression of the sealing ring 12, which could cause displacement, and to leave a certain space for deformation sealing.

[0019] The outer casing 4 has a clearance part 7 at the outlet connector 3, and the diameter of the clearance part 7 is smaller than the diameter of the outer casing 4. Generally, three different lengths are designed at this location to meet the clearance requirements and prevent volume interference.

[0020] The outer casing 4 is equipped with a rotating pressure rod 8, which, during rotation, links the movable component 1 to move axially back and forth. This is one embodiment; the pressure rod 8, in conjunction with a piston, compresses the space within the piston cavity, thereby driving the movable component 1 to move. Alternatively, the drive can be directly controlled by an air source through an additional air hole 9, using the movable component 1 itself as a piston rod. When not in use, the air hole 9 can be sealed with an internal hex nut or similar material. A thumb valve can also be used to lift or press down the lever to control the drive air source, or directly link the piston to adjust the volume of the piston cavity; these details are not elaborated upon here. In this embodiment, the pressure rod 8 is further provided with a protruding interlocking part 10, which has a connecting hole 11 for linkage control with other mechanisms. The connecting hole 11 facilitates installation, connection, and operation. It should be noted that during implementation, a piston-driven pneumatic drive method can be used, and the air hole 9, pressure rod 8, and thumb valve can be produced simultaneously; these three are not contradictory structures.

[0021] The gas pipeline has a built-in one-way valve in the flow direction, enabling quick, leak-free connection and quick, leak-free disconnection. In the disconnected state: it closes the channel to the test end, preventing gas leakage from the connector tip (and also preventing external air from entering the test system). In the connected state: when the connector is correctly inserted and locked at the workpiece port, the channel opens, allowing test gas to enter the workpiece. In the disconnected state: when the connector is pulled out, it quickly resets and closes the channel, preventing gas leakage (and also preventing the instantaneous release of gas from the workpiece, which could cause contamination or danger). This product is generally compatible with most one-way valves, depending on the specific application requirements; it is a mature technology.

[0022] The sealing ring 12 is an O-ring made of nitrile rubber through one-time injection molding, which facilitates replacement and reduces production and usage costs, while meeting design requirements. The outer shell 4 has a piston cavity formed together with the end of the movable part 1. In this embodiment, a piston-driven method is used as an example, but it is not the only limitation.
