[0025] Please see Figure 1-3 This utility model provides a technical solution: a quick-connect structure for automotive nylon tubing, including a first connecting tube 1 and a second connecting tube 2. A sleeve frame 3 is fixedly connected to the end of the first connecting tube 1, and a plug 4 is fixedly connected to the end of the second connecting tube 2. The plug 4 is sleeved with the sleeve frame 3, and a sealing gasket 5 is provided at the connection between the plug 4 and the sleeve frame 3. A limiting device 6 is provided on the outside of the sleeve frame 3. A slot is provided on the surface of the plug 4, and the limiting device 6 is engaged with the slot of the plug 4. A reinforcing device 7 is provided inside the plug 4, and a slot is provided on the inner wall of the sleeve frame 3, with the reinforcing device 7 corresponding to the slot of the sleeve frame 3. The plug 4 fits into the sleeve 3, facilitating quick installation by workers. A sealing gasket 5 is installed at the connection between the plug 4 and the sleeve 3, significantly improving the sealing performance of the joint and preventing fluid leakage, thereby ensuring the safe and efficient operation of the transmission system. The limiting device 6 and the reinforcing device 7 ensure a stable connection between the plug 4 and the sleeve 3, effectively preventing the joint from loosening or falling off due to vibration or pressure changes. The design of the limiting device 6 makes the insertion and removal of the plug 4 simpler and faster, while the self-adjusting function of the reinforcing device 7 further simplifies the installation steps and improves work efficiency.

[0026] The plug 4 has a guide block 8 on its side wall, and the sleeve 3 has a mounting groove on its side wall. The guide block 8 corresponds to the mounting groove of the sleeve 3. The guide block 8 is provided so that when the plug 4 and the sleeve 3 are installed, the guide block 8 corresponds to the mounting groove of the sleeve 3, thereby improving the overall installation accuracy.

[0027] The limiting device 6 includes a first spring 61, a pressing block 62, a locking rod 63, a pull rod 64, and a pull ring 65.
