[0002] Central air conditioning is a system that centrally handles air conditioning loads. Compared to traditional independent air conditioners, it has more powerful functions. Central air conditioning has various structures, and copper pipes are a key component for the normal circulation of refrigerant. When installing central air conditioning, it is usually necessary to connect the copper pipes of the indoor and outdoor units through a docking device. However, the existing docking devices for copper pipes in central air conditioning are not very secure and may leak or loosen during use.

[0003] As disclosed in announcement number CN220770390U, a copper pipe docking device for central air conditioning includes a sleeve made of rubber. The inner walls of the sleeve have symmetrical slots for inserting copper pipes at both ends. The side walls of the sleeve have symmetrical grooves at both ends outside the slots. The side wall of the groove near the slot is wedge-shaped, and the side wall away from the slot has internal threads. Fasteners for fixing the copper pipes are screwed onto the grooves. This utility model has a simple structure and reasonable design. Through the arrangement of the sleeve, slot, groove, internal threads, fasteners, sleeve, external threads, and nuts, it achieves the docking of air conditioning copper pipes. The wedge-shaped side wall of the groove near the slot, after the fastener is screwed into the groove, tightly presses the copper pipe against the groove wall, achieving a good sealing effect. This device has a simple structure, is easy to manufacture and install, and has a low cost, which helps enterprises save costs. However, its connection firmness is relatively poor during docking and installation. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figure 1 and Figure 2In this embodiment of the utility model, a central air conditioning docking device includes: an intermediate docking seat 1, a docking locking cap 2 screwed onto the outer side of one end of the intermediate docking seat 1, a docking locking ring 3 embedded on the inner side of one end of the intermediate docking seat 1, and an air conditioning copper pipe 4 inserted into the docking locking ring 3.

[0022] Reference Figure 3 The intermediate docking seat 1 includes a cylindrical docking seat body 10. One end of the cylindrical docking seat body 10 has a beveled inner annular groove 11. One end of the inner annular groove 11 has a copper tube insertion groove 12. One end of the copper tube insertion groove 12 has a fixed copper tube inner insertion connector 13. The outer side of the copper tube inner insertion connector 13 has a fixed anti-slip texture 14. The cylindrical docking seat body 10 has a through-hole 15 for a copper tube running through its center. The cylindrical docking seat body 10 has an outer... One end of the cylindrical docking seat is provided with an external thread 16. A central hexagonal seat 17 is fixedly provided in the middle of the outer side of the cylindrical docking seat 10. There are two sets of external threads 16. There are two sets of inclined annular grooves 11, copper tube insertion annular grooves 12, copper tube inner insertion pipes 13 and outer anti-slip textures 14. The two sets of inclined annular grooves 11, copper tube insertion annular grooves 12, copper tube inner insertion pipes 13 and outer anti-slip textures 14 are symmetrically arranged at both ends of the cylindrical docking seat 10.

[0023] Reference Figure 4 The locking cap 2 includes a locking cap hexagonal seat 20. One end of the locking cap hexagonal seat 20 has a locking cap internal thread hole 21. One end of the locking cap hexagonal seat 20 is fixedly connected to a locking tube limiting sleeve 22. One end of the locking tube limiting sleeve 22 has a copper tube through hole 23.

[0024] The above solution involves screwing two sets of locking caps 2 onto both sides of the intermediate docking seat 1 via external threads 16, and then pressing the locking ring 3 inward through the locking tube limiting sleeve 22. This tightly presses the air conditioning copper pipe 4 onto the outer surface of the copper pipe insert 13. This structure allows for rapid docking of the central air conditioning copper pipes and provides better docking stability. Furthermore, the anti-slip texture 14 on the outer surface of the copper pipe insert 13 further enhances the docking stability.

[0025] Reference Figure 5 The locking ring 3 includes a locking ring body 30, with an outer inclined surface 31 on the outside of the locking ring body 30 and a straight circular hole structure on the inside of the locking ring body 30.

[0026] The working principle of this utility model is as follows: First, the hexagonal locking cap seats 20 of the two sets of locking caps 2 are placed outwards through the copper tube through-holes 23 onto the outside of the two sets of air conditioning copper tubes 4. Next, the narrow edges of the outer inclined surfaces 31 of the two sets of locking rings 3 are placed outwards onto the outside of the two sets of air conditioning copper tubes 4. At this point, the two sets of air conditioning copper tubes 4 are placed on the outside of the inner insertion pipes 13 of the two sets of copper tubes until the air conditioning copper tubes 4 are embedded in the insertion ring grooves 12 of the two sets of copper tubes. Then, the two sets of locking rings 3 are pushed towards the middle locking seat 1 to embed them into the inclined surface. Inside the annular groove 11, the two sets of locking caps 2 are screwed onto both sides of the middle docking seat 1 via the external threads 16. The locking ring 3 is then pressed inward by the locking tube limiting sleeve 22, thereby tightly pressing the air conditioning copper pipe 4 onto the outer surface of the copper pipe insert 13. This structure allows for quick docking of the central air conditioning copper pipes and provides better docking firmness. The external anti-slip texture 14 on the outer surface of the copper pipe insert 13 further enhances the docking firmness.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
