[0008] Optionally, at least two bevel grooves are formed on the outer circumference of the hexagonal screw block, the limiting rod is located in the bevel groove, and a plurality of bevel teeth are formed on the end surface of one side of the limiting rod close to the joint, which cooperate with the bevel groove.

[0009] Optionally, a hose is sleeved on the outer circumference of the mounting ring.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the clamping assembly, the hose can be fixed on the copper joint by pulling the slip ring, and then the limit rod also resets the slip ring through the teeth to make the hose installation more compact and not easy to fall off. When it needs to be disassembled, the hose can be disassembled by rotating the limit rod, making the installation and disassembly of the hose simpler and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in Figure 1-2, a compression copper joint pipe fitting includes a joint 10, a hexagonal screw block 12 and a mounting ring 11 are fixed on the outer peripheral side of the joint 10, the mounting ring 11 is located at the end of the joint 10, a hose 13 is sleeved on the outer peripheral side of the mounting ring 11, the hexagonal screw block 12 is located in the middle part of the joint 10, and a compression assembly is also sleeved on the outer peripheral side of the joint 10, the compression assembly includes a slip ring 14, a retaining ring 15 is fixed to one end face of the slip ring 14, the end face of the mounting ring 11 away from the hexagonal screw block 12 is an inclined surface, and the end face of the mounting ring 11 close to the hexagonal screw block 12 is provided with a pressing groove 18, the pressing groove 18 matches the retaining ring 15, and the slip ring 14 is also rotatably connected to a limit rod 17, and a torsion spring is provided at the rotational connection between the limit rod 17 and the slip ring 14, and the limit rod 17 extends into the hexagonal screw block 12.

[0017] The slip ring 14 is located between the mounting ring 11 and the hexagonal screw block 12, and the retaining ring 15 is installed on one end face of the slip ring 14 close to the mounting ring 11. The retaining ring 15 is rotatably connected to one end face of the mounting ring 11 with a plurality of auxiliary wheels 16. At least two anti-slip rings are also provided on the outer peripheral side of the retaining ring 15. At least two helical tooth grooves are provided on the outer peripheral side of the hexagonal screw block 12. A limiting rod 17 is located in the helical tooth groove. A plurality of helical teeth are provided on one end face of the limiting rod 17 close to the joint 10, which cooperate with the helical tooth groove.

[0018] When in use, the hose 13 is put on the mounting ring 11. After passing over the mounting ring 11, the hose 13 will shrink and stick to the surface of the connector 10. At this time, the slip ring 14 is pulled in the direction close to the mounting ring 11. At this time, the buckle ring 15 will press the hose 13 on the inner side of the buckle ring 15, and then continue to squeeze it into the pressing groove 18. The auxiliary wheel 16 can make the squeezing process of the hose 13 smoother. When the hose 13 is completely squeezed between the mounting ring 11 and the buckle ring 15, the limit rod 17 is also reset by the teeth to limit the slip ring 14, so that the hose 13 is installed more tightly and not easy to fall off. When disassembly is required, the limit rod 17 needs to be manually rotated to the side away from the connector 10 to disengage the limit rod 17 from the hexagonal screw block 12. At this time, the slip ring 14 can be pulled in the direction close to the hexagonal screw block 12 to disengage the buckle ring 15 from the pressing groove 18, and then the hose 13 can be pulled out, making the installation of the hose 13 simpler and faster.

[0019] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
