Further preferably, the thickness of the middle section between two adjacent notches remains unchanged, so that when the clamping block passes over the notch and rotates a certain angle, the clamping plate has a wedge-shaped slope or a trapezoidal slope, which can realize the buckle connection and the locking of the male Luer connector 1 and the female Luer connector 2. In addition, in the case of combining with the embodiment in which the first sealing ring and the second sealing ring are arranged on the end surface of the male matching portion, the sealing ring can be pressed while locking, which can further improve the sealing effect.

[0049] When the pipeline quick-insert connector protected by the utility model connects two sections of pipelines, the first pipe connector of the male Luer connector 1 is connected to one end of the pipeline, and the female Luer connector 2 is connected to the other end of the pipeline, and then the male Luer connector 1 and the female Luer connector 2 are connected by quick-insert buckle through the first clamping plate 102 and the first clamping part 202 to achieve pipeline connectivity. The rotating clamping structure makes the connection fast and firm, improves the efficiency of liquid transfer, and can achieve stable and tight connection of pipelines between two different bag bodies through this quick-insert clamping method. When there is no need to transfer liquid, the male Luer connector 1 and the female Luer connector 2 are disconnected, and then the male Luer plug 3 is quickly connected to the female Luer connector 2 to block the pipeline on one side of the female Luer connector to prevent liquid leakage in the pipeline at this end of the female Luer connector 2, and the female Luer plug 4 is quickly connected to the male Luer connector 1 to block the pipeline on one side of the male Luer connector 1 to prevent liquid leakage in the pipeline at this end of the male Luer connector 1.
