[0022] The present utility model provides a pneumatic quick connector, including a connector body 101 and a clearance groove 102, and the clearance groove 102 is arranged inside the connector body 101;
[0023] It further includes a connecting component, which includes a connecting thread 103, a first sealing ring 104, a fitting chamfer 105, a fixing part and an auxiliary part. The outer surface of one end of the joint body 101 has the connecting thread 103. The first sealing ring 104 is detachably connected to the joint body 101 and is located inside the joint body 101, and the first sealing ring 104 is located above the clearance groove 102. The fitting chamfer 105 is arranged on the outer surface of the joint body 101. The fixing part is arranged above the joint body 101, and the auxiliary part is arranged outside the joint body 101.
[0024] In this embodiment, the connecting thread 103 enables the joint body 101 to be more conveniently connected to an external device at one end. The fitting chamfer 105 enables the joint body 101 to have a better fit with the external device during connection. By controlling the fixing part, the device connected to the other end of the joint body 101 can be fixed, making the connection more firm, and solving the problem that the stability is weak when the pneumatic quick-connect joint is connected to an external device, resulting in an insecure connection.
[0025] Further, the fixing part includes a fixing ring 106, a chute 107, a slider 108, a fixing block 109, a sliding rod 110, a rotating ring 111 and a limiting groove 112. The fixing ring 106 is fixedly connected to the joint body 101 and is located above the joint body 101. The surface of the fixing ring 106 has the chute 107. The slider 108 is slidably connected to the chute 107 and is located inside the chute 107, and the chute 107 is adapted to the slider 108. The fixing block 109 is fixedly connected to the slider 108 and is located at one end of the slider 108 away from the chute 107. The sliding rod 110 is fixedly connected to the slider 108 and is located above the slider 108. The rotating ring 111 is rotatably connected to the fixing ring 106 and is located above the fixing ring 106. The surface of the rotating ring 111 has the above-mentioned limiting groove 112, and the limiting groove 112 is adapted to the sliding rod 110.
[0026] In this embodiment, by rotating the rotating ring 111, the limiting groove 112 rotates accordingly, causing the sliding rod 110 to move towards the center of the rotating ring 111 under the cooperation of the slider 108 and the chute 107, driving the slider 108 to slide towards the center of the rotating ring 111 in the chute 107, thereby driving the fixing block 109 to move until it fits against the outer wall of the external device, achieving the purpose of fastening the external device.
[0027] Further, the fixing component further includes a connecting ring 113 and a fastening block 114. The connecting ring 113 is fixedly connected to the rotating ring 111 and is located outside the rotating ring 111.
