[0007] Preferably, the joint and the connecting pipe are integrally injection-molded.

[0008] Preferably, a protective cover is fixedly connected to the side wall of the joint, and a gap is provided between the protective cover and the joint.

[0009] Preferably, a sealing ring is fixedly connected to the inner wall of the connecting pipe, a guide ring is fixedly connected to the inner wall of the connecting pipe located on the sealing ring, and the inner wall of the guide ring is provided with a chamfered corner.

[0010] Preferably, an identification plate is fixedly connected to the side wall of the connecting pipe.

[0012] Compared with the prior art, the utility model provides a plug-in locking structure and a plug-in connector, which has the following beneficial effects:

[0013] 1. The plug-in locking structure and the plug-in connector, when the interior of the tube is filled with liquid and is affected by pressure, the U-shaped clamp is squeezed and pushed to slide along the inner wall of the opening. Since the U-shaped clamp has good elasticity, the U-shaped clamp rebounds and is pressed against the side wall of the tube, thereby ensuring the tightness of the connection and improving the anti-pullout effect.

[0014] 2. The plug-in locking structure and the plug-in parts can improve the tightness of the U-shaped clamp sliding inside the joint through the sealing gasket to prevent leakage. The sealing ring and the guide ring can improve the stability and sealing of the pipe body plugged into the connecting pipe. The identification plate can improve the recognition effect.

[0015] 3. The plug-in locking structure and the plug-in connector are plugged into the pipe opening of another pipe body or machine body. The anti-pullout ring can improve the anti-pullout effect, and the limit stop ring can play a blocking effect to prevent loss caused by excessive plug-in. BRIEF DESCRIPTION OF THE DRAWINGS
