The sleeve 14 has a through insertion hole 15 inside. A plurality of first sealing rings 13 are installed on the end of the pipe body 11 near the external thread 12, and a plurality of second sealing rings 16 are installed on the inner wall of the end of the sleeve 14 near the pipe body 11. The end of the pipe body 11 near the external thread 12 is made of copper. In use, the tube body 11 is installed on the spindle via the external thread 12, and the first sealing ring 13 is installed at the end of the tube body 11. It is used to seal the connection between the tube body 11 and the spindle to prevent media leakage. The other tube is inserted into the insertion hole 15 of the sleeve 14, and the second sealing ring 16 fits tightly against the outer wall of the inserted tube to achieve bidirectional sealing under quick insertion. If the spindle overheats abnormally during production, the staff can quickly and conveniently remove the tube to deal with the abnormality without tools. The threaded connection section of the quick-connect connector is made of copper, which has good sealing performance, high pressure resistance, and is not easy to rust or corrode, and the connection to the spindle is firm.

[0017] Furthermore, such as Figure 1-5 As shown, a lower ball seat 21 is fixedly connected to one end of the tube body 11 away from the external thread 12. An upper ball seat 22 is detachably connected to the top of the lower ball seat 21 by bolts. A spherical cavity 23 is formed inside the upper ball seat 22 and the lower ball seat 21. A spherical seat 24 is provided inside the spherical cavity 23. A through hole is opened inside the spherical seat 24. The sleeve 14 is fixedly connected to the end of the through hole. The sleeve 14 passes through the top of the upper ball seat 22. During installation, a lower ball seat 21 is fixed to the end of the pipe body 11 away from the external thread 12. The lower ball seat 21 is connected to the upper ball seat 22 by bolts, and a spherical cavity 23 is formed inside. The ball seat 24 is placed in the spherical cavity 23 and can rotate freely. The through hole communicates with the sleeve 14 to allow the medium to flow smoothly. The bolt connection structure of the upper and lower ball seats 21 realizes the stable positioning of the ball seat 24, and at the same time facilitates disassembly and maintenance. The ball seat 24 can rotate at multiple angles in the spherical cavity 23, effectively compensating for the deviation of the pipe angle during pipe installation and improving installation flexibility and fitting accuracy.

[0018] Furthermore, such as Figure 1-5 As shown, a support ring 31 is fixedly connected to the middle of the insertion hole 15, and a plurality of spring pieces 32 are fixedly connected to the top of the support ring 31. The spring pieces 32 have an integrally formed barb portion 33 in the middle. The plurality of spring pieces 32 are evenly distributed in a ring array around the top of the support ring 31. The top of the spring pieces 32 is inclined towards the inner wall of the sleeve 14. A pressing sleeve 41 is slidably connected to the top of the sleeve 14. The bottom end of the pressing sleeve 41 is located at the top of the spring piece 32. A plurality of grooves 51 are formed on the surface of the spherical seat 24.

When the pressing sleeve 41 is pushed down, its bottom end squeezes the spring piece 32 outward, so that the barb part 33 is disengaged from the outer wall of the pipe, and the pipe can be easily pulled out, which is convenient to operate. A rubber ring 52 is provided in the groove 51 on the surface of the spherical seat 24. The rubber ring 52 fits tightly with the inner wall of the spherical cavity 23, which ensures the sealing while allowing the spherical seat 24 to rotate flexibly in the cavity.

[0019] Furthermore, such as Figure 1-5 As shown, the tube body 11 is a 90-degree vertical bend, and a spring 6 is fixed to the top of the sleeve 14. The spring 6 is sleeved on the surface of the pressing sleeve 41. When in use, the tube body 11 is designed at a 90º angle, which can effectively prevent multiple water and air tubes from folding and ensure water and air circulation. The top of the sleeve 14 is equipped with a spring 6, which supports the pressing sleeve 41 and keeps it away from the spring piece 32.

[0020] Working principle: During use, the tube body 11 is installed on the spindle via the external thread 12. The first sealing ring 13 is installed at the end of the tube body 11, which is used to seal the connection between the tube body 11 and the spindle to prevent media leakage. The other tube is inserted into the insertion hole 15 of the sleeve 14, and the second sealing ring 16 fits tightly against the outer wall of the inserted tube to achieve bidirectional sealing under quick insertion. If the spindle overheats abnormally during production, the operator can quickly and conveniently remove the tube without tools to handle the abnormality. The threaded connection section of the quick-connect fitting is made of copper, which has good sealing performance, high pressure resistance, and is not easy to rust or corrode, and the connection to the spindle is firm. During installation, a lower ball seat 21 is fixed to the end of the pipe body 11 away from the external thread 12. The lower ball seat 21 is connected to the upper ball seat 22 by bolts, and a spherical cavity 23 is formed inside. The ball seat 24 is placed in the spherical cavity 23 and can rotate freely. The through hole communicates with the sleeve 14 to allow the medium to flow smoothly. The bolt connection structure of the upper and lower ball seats 21 realizes the stable positioning of the ball seat 24, and at the same time facilitates disassembly and maintenance. The ball seat 24 can rotate at multiple angles in the spherical cavity 23, effectively compensating for the deviation of the pipe angle during pipe installation and improving installation flexibility and fitting accuracy. During use, a support ring 31 is fixedly connected to the insertion hole 15 in the middle of the sleeve 14. The spring pieces 32 evenly distributed on the top of the support ring 31 and its integrally formed barb part 33 can be clamped into the outer wall of the pipe to achieve quick positioning and anti-dislodgement function. When the pressing sleeve 41 is pushed down, its bottom end squeezes the spring piece 32 outward, so that the barb part 33 is disengaged from the outer wall of the pipe, and the pipe can be easily pulled out, which is convenient to operate. A rubber ring 52 is provided in the groove 51 on the surface of the spherical seat 24. The rubber ring 52 fits tightly with the inner wall of the spherical cavity 23, which ensures the sealing while allowing the spherical seat 24 to rotate flexibly in the cavity.
