[0014] Such as figure 1 , figure 2 As shown, the present invention is a pneumatic quick connector, which includes a female connector 1 connected with an air inlet pipe and a male connector 6 connected with an outlet pipe. A locking sleeve 12 is fixedly installed on the air outlet end of the female connector 1. The locking sleeve 12 and the female connector 1 are connected by threads. A guide sleeve 7 is sandwiched between the locking sleeve 12 and the inner wall of the female connector 1, and a check valve core 3 that can move back and forth is movably inserted in the inner hole of the guide sleeve 7. The inner wall of the guide sleeve 7 is provided with a groove 7.1, which is embedded with a Y-shaped sealing ring 8. When the check valve core 3 is inserted into the inner hole of the guide sleeve 7, the Y-shaped sealing ring 8 is compared with other sealing rings. The friction force is smaller, and it is not easy to damage or fall off, which facilitates the installation of the ...
