[0017] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A nylon quick-connect fitting includes: a male connector assembly 1, a female connector assembly 2, and a nylon tube 3. The male connector assembly 1 includes a left connector 11, an inner sleeve 12, and a fastening sleeve 13. The left connector 11 has a right stepped channel 111 inside. The inner sleeve 12 is snapped into the left connector 11 and has a slot 123. The fastening sleeve 13 is inserted into the inner sleeve 12. The nylon tube 3 is placed inside the fastening sleeve 13 and pushes the fastening sleeve 13 outward to snap into the slot 123. The nylon tube 3 is connected to the left end of the right stepped channel 111. The female connector assembly 2 includes a middle sleeve 21 and a right connector 22. The left end of the middle sleeve 21 is inserted into the right end of the right stepped channel 111 and is connected to the left end of the right stepped channel 111. The right connector 22 is sleeved on the right end of the middle sleeve 21 and is internally connected.

[0020] like Figures 1-3 As shown, the working principle of this utility model is as follows: In the male connector assembly, after the nylon tube is inserted into the fastening sleeve, the insertion of the nylon tube exerts an outward pushing force on the inserts due to the spaced-apart blocks at the right end of the fastening sleeve, causing the inserts to open outward. The inner sleeve has a slot, and the opened inserts can be engaged into the slot. This cooperation between the fastening sleeve and the inner sleeve achieves a quick and stable connection between the nylon tube and the male connector assembly. No additional tools are required, the operation is simple and convenient, and it greatly improves the installation efficiency of the nylon tube and the connector.

[0021] Regarding the connection between the male and female connector assemblies, the left end of the intermediate sleeve inserts into the right end of the right stepped channel of the left connector, with the two connected. This snap-fit ​​connection allows the male and female connectors to quickly align, enabling smooth fluid transfer between the male and female connector assemblies. Compared to traditional threaded connections or other complex connection methods, the quick-connect snap-fit ​​connection significantly reduces connection time, making it particularly suitable for work scenarios requiring frequent connection and disassembly.

[0022] As a further preferred embodiment, the left connector 11 is further provided with a left stepped channel 112. The left stepped channel 112 includes a channel 113, a channel 2 114, and a channel 3 115 that are connected to the right in sequence and have decreasing inner diameters. The right stepped channel 111 includes a channel 4 116 and a channel 5 117 that are arranged to the left in sequence and have decreasing inner diameters. The channel 5 117 extends into the channel 113 and has an outer diameter smaller than that of the channel 3 115. A sealing ring 1 is provided inside the channel 2 114 and is sleeved on the outside of the nylon tube 3. 4. The inner sleeve 12 includes a retainer 121 and a retainer 122. The retainer 121 and the retainer 122 are sequentially fitted to the left inside the second channel 114 and sleeved on the outside of the nylon tube 3. The retainer 122 is snapped into the left connector 11. The slot 123 is located between the retainer 121 and the retainer 122. The right end of the fastening sleeve 13 is provided with an insert 131 at intervals. The insert 131 is inserted through the nylon tube 3, opens outwards, and snaps into the slot 123. The right end of the nylon tube 3 abuts against the right end face of the outside of the fourth channel 116.

[0023] The left connector features a stepped left channel and a stepped right channel inside. Channel five extends into channel one and has a smaller outer diameter than channel three. This stepped channel structure provides installation positions and spatial layout for each component, resulting in a more compact and stable connection. A sealing ring inside channel two is fitted onto the outside of the nylon tube, effectively preventing fluid leakage from the gap between the nylon tube and the left connector, ensuring a tight seal. An inner sleeve and a retaining sleeve are sequentially fitted inside channel two and onto the outside of the nylon tube. The retaining sleeve engages inside the left connector, with a groove located between the retaining sleeve and the retaining sleeve, further enhancing the stability and sealing of the connection between the nylon tube and the left connector.

[0024] As a further preferred embodiment, a second sealing ring 5 is provided on the groove at the left end of the middle sleeve 21, and the second sealing ring 5 is fitted inside the right end of the right stepped channel 111. A third sealing ring 6 is provided on the groove at the right end of the middle sleeve 21, and the third sealing ring 6 is fitted inside the right side of the right connector 22. A fourth sealing ring 7 is provided on the groove in the middle of the middle sleeve 21, and the fourth sealing ring 7 is fitted inside the left side of the right connector 22. The installation of these sealing rings can form a sealing barrier at each connection gap when the male connector assembly and the female connector assembly are connected, effectively preventing fluid leakage from the connection of the male and female connectors.

[0025] As a further preferred embodiment, the right connector 22 is provided with a threaded groove 221 on its exterior. This threaded connection allows the quick-connect fitting to be securely installed in various piping systems or equipment, increasing the flexibility and versatility of its use.
