[0021] Please see Figures 1-6This utility model provides a technical solution: a quick-connect fitting for nylon tubing, comprising a tubing connector 1 and a fixing mechanism 5. One side of the inner wall of the tubing connector 1 is connected to a first-order nylon tubing 2, and the other side is connected to a second-order nylon tubing 3. Sealing rings 4 are connected to both sides of the outer wall of the tubing connector 1. The fixing mechanism 5 includes a fixing ring 501, a limiting strip 502, a magnetic ring 503, a limiting ring 504, an arc-shaped fixing pin 505, a transmission block 506, a rotating ring 507, an extension seat 508, a circular track 509, a spring 510, a rotating seat 511, and an iron... The limiting block 512 and the circular slide rail 513, as well as the outer walls of the first nylon pipe 2 and the second nylon pipe 3, are all connected to a fixing ring 501. A limiting strip 502 is fixedly connected to one side of the outer wall of the fixing ring 501. A limiting ring 504 is welded to the side of the pipe connector 1 near the sealing ring 4. A limiting groove is formed inside the limiting ring 504, and the limiting strip 502 extends into it. An arc-shaped fixing pin 505 is connected inside the limiting strip 502, and a transmission block 506 is welded to one side of the outer wall of the arc-shaped fixing pin 505. A rotating ring 507 is welded to the middle of the outer wall of the transmission block 506. The limiting strip 502 is shaped like a "..." The components are arranged in a cross shape. A fixing groove is provided inside the limiting strip 502, into which an arc-shaped fixing pin 505 extends. A circular slide rail 513 is slidably connected inside the rotating ring 507, and the inner wall of the circular slide rail 513 is welded to the outer wall of the pipe connector 1. An extension seat 508 is welded to the side of the rotating ring 507 away from the transmission block 506. A circular track 509 is slidably connected inside the extension seat 508, and support blocks are connected to both sides of the outer wall of the circular track 509. The inner wall of the support blocks is welded to the pipe connector 1. The support blocks and the extension seat 508 are arranged in a cross shape. The outer wall of the circular track 509 is sleeved with… A spring 510, an extension seat 508, and a circular track 509 are connected to the spring 510 to form an elastic telescopic mechanism; a magnetic ring 503 is connected to the side of the fixed ring 501 away from the limiting strip 502, and an iron limiting block 512 is magnetically connected to the outer wall of the magnetic ring 503, and a rotating seat 511 is rotatably connected inside the iron limiting block 512; one side of the outer wall of the rotating seat 511 is welded to the limiting ring 504, and the rotating seat 511 and the iron limiting block 512 are arranged in a "+" shape; the rotating seat 511 has an "L" shape structure, and the rotating seat 511 and the iron limiting block 512 have a "U" shape structure.

[0022] In practical implementation, during the rapid connection of nylon tubing via the connector, when it is necessary to fix the nylon tubing, since the fixing ring 501 is connected to the limiting strip 502, firstly move nylon tubing 2 and nylon tubing 3 to align with both sides of the tubing connector 1. At this time, the fixing ring 501 drives the limiting strip 502 to insert into the limiting ring 504, thereby limiting nylon tubing 2 and nylon tubing 3 to prevent them from rotating freely. Then, push the rotating ring 507 to move along the circular slide rail 513. Since the rotating ring 507 is connected to the transmission block 506 and the extension seat 508, the spring 510 returns to its original position, generating elastic force that causes the extension seat 508 to move along the circular track 509, thereby assisting the rotating ring 507 in rotating. Furthermore, since the transmission block 506 is connected to the arc-shaped fixing pin 505... When the transmission block 506 moves, it will drive the arc-shaped fixing pin 505 to move together until the arc-shaped fixing pin 505 passes through the limiting strip 502. Then, the limiting strip 502 is fixed to prevent it from moving in a straight line. Since the rotating seat 511 and the iron limiting block 512 are rotatably connected, the iron limiting block 512 is then rotated to fit with the magnetic ring 503 to form a magnetic attraction connection. This provides a secondary limit for the first nylon tube 2 and the second nylon tube 3, improving their stability. Therefore, there is no need to repeatedly rotate the connecting joint or the nylon tube. Simply push the rotating ring 507 so that the arc-shaped fixing pin 505 passes through the limiting strip 502 to fix the nylon tube. The operation is simple and convenient and facilitates subsequent disassembly and maintenance. Thus, when using the quick-connect fitting for nylon tubes, it can facilitate the quick fixation of nylon tubes.

[0023] When it is necessary to disconnect the nylon tubing from the connector, first rotate the iron limiting block 512 to disengage it from the magnetic ring 503. Then, rotate the rotating ring 507 to move the transmission block 506 and the extension seat 508. At this time, the movement of the extension seat 508 will cause the spring 510 to deform. Then, the spring 510 will reset the arc-shaped fixing pin 505 to return to its original position until the transmission block 506 drives the arc-shaped fixing pin 505 to disengage from the limiting strip 502, thereby releasing the fixation of the nylon tubing. Then, move the first nylon tubing 2 and the second nylon tubing 3 in a straight line to disconnect the nylon tubing from the connector for maintenance.

[0024] In summary, when using this quick-connect nylon tubing connector, first move the tubing connector 1 so that one side aligns with nylon tubing 2, then move nylon tubing 3 to align with the other side of the connector 1. The sealing ring 4 ensures a tight seal at the connection point, thus connecting the two sets of nylon tubing. This is existing technology and will not be elaborated upon here. The fixing mechanism 5 inserts the limiting strip 502 into the limiting ring 504, thereby limiting the nylon tubing and preventing it from rotating freely. Then, the spring force generated by the spring 510 drives the rotating ring 507 to rotate until the arc-shaped fixing pin 505 penetrates the limiting strip 502, thus fixing the limiting strip 502 and preventing linear movement of the nylon tubing. Therefore, simply pushing the rotating ring 507 is sufficient to fix the nylon tubing. The operation is simple and convenient, and subsequent disassembly and maintenance are easy. Content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
