Cover internal thread 14, the external screw thread on external thread column 7 are connected with protective cover internal thread 14.
Specifically, external thread column 7 is threaded through between rotating part 2 and copper nut 4, in order to make external thread column 7 that can not be pierced by
Rotating part 2 and copper nut 4, play position-limiting action, and the diameter of bore of external thread column 7 is less than the outer circumference diameter and copper spiral shell of rotating part 2
The outer circumference diameter of mother 4.When copper nut 4 is installed, with reference to Fig. 5-6, external thread column 7 is first penetrated to the external screw thread 3 of pipe fitting 1, because
The diameter of bore of external thread column 7 is less than the outer circumference diameter of rotating part 2, and external thread column 7 is blocked by rotating part 2.With reference to Fig. 7-8, then
Copper nut internal thread 15 is connect with the external screw thread 3 of pipe fitting 1, outer-hexagonal rotating part 2 and outer is clamped respectively with tools such as spanners
Hexagonal copper nut 4, while applying screw-down torque, the circular conical surface 12 of the horn mouth 13 and pipe fitting 1 that make copper nut 4 forms sealing
Face.Finally, protective cover 5 is inserted in copper nut 4 from one end of copper nut 4, the external screw thread on external thread column 7 and protective cover internal thread
14 are connected, and external thread column 7 is fastened as a whole with protective cover 5, because the diameter of bore of external thread column 7 is less than copper nut 4
Outer circumference diameter so that protective cover 5 can not the left and right play on copper nut 4 in an axial direction, it is ensured that protective cover 5 covers on copper nut always
4 periphery achievees the purpose that copper nut 4 is non-disconnectable.
Further, as shown in figure 9, in order to keep external thread column 7 and the connection of protective cover 5 more reliable, on external thread column 7
External screw thread is not easy to unclamp after connecting with protective cover internal thread 14, and bulge-structure 8, protrusion knot are arranged on the periphery of external thread column 7
Structure 8 has an inclined-plane, and the inside of protective cover 5 is correspondingly provided with the notch 9 coordinated with bulge-structure 8.It is outer on external thread column 7
Screw thread and protective cover internal thread 14 tighten connect when because bulge-structure 8 has an inclined-plane, protective cover internal thread 14 can
It is connected with the external screw thread on external thread column 7 with continuing sliding along inclined-plane, and after screw-thread fit connection finishes, protrusion
Structure 8 is embedded in the notch 9 on protective cover 5, and the external screw thread on external thread column 7 can not be unclamped with protective cover internal thread 14, even
It connects more reliable.
Embodiment three, as shown in figures 10-13, position limiting structure are the buckle 10 being arranged on protective cover, buckle 10 and copper spiral shell
The periphery clamping of female 4 one end.
Specifically, the material of buckle 10 is elastic material, convenient for deformation connection.When copper nut 4 is installed, 0-11 referring to Fig.1,
Copper nut internal thread 15 is connect with the external screw thread 3 of pipe fitting 1 first, 2 He of outer-hexagonal rotating part is clamped respectively with tools such as spanners
Outer-hexagonal copper nut 4, while applying screw-down torque, the circular conical surface 12 of the horn mouth 13 and pipe fitting 1 that make copper nut 4 forms sealing
Face.2-13 referring to Fig.1, then there is one end of buckle 10 to be inserted in copper nut 4 from one end of copper nut 4 protective cover 5, because of buckle
10 have elasticity, and when buckle 10 moves between copper nut 4 and rotating part 2, buckle 10 and one end of copper nut 4 are clamped.For
Make protective cover 5 can not on copper nut 4 left and right play in an axial direction, it is ensured that protective cover 5 covers on the periphery of copper nut 4 always,
Diameter of bore that buckle 10 in the inside circumference of protective cover 5 is surrounded is less than the outer circumference diameter and copper nut 4 of rotating part 2
Outer circumference diameter.
Further, once the rotating part 2 of pipe fitting 1 is pierced by from position limiting structure in order to prevent, protective cover 5 is in an axial direction
Play and cause copper nut 4 expose, add additonal limit structure in the other end of protective cover 5.When copper nut 4 and pipe fitting 1
After being fastenedly connected, copper nut 4 can not be pierced by from additonal limit structure, it is ensured that protective cover 5 covers on the outer of copper nut 4 always
It encloses, the protection of copper nut 4 is made more to insure, is safer.
The setting of additonal limit structure is also varied, if ensure copper nut 4 connect with pipe fitting 1 after copper nut 4
It can not be pierced by from additonal limit mechanism.In the present invention, additonal limit structure is the buckle living that can be pulled（Not
Diagram）, when protective cover 5 is inserted in copper nut 4, buckle living attaches the inner wall in protective cover 5, does not influence being inserted in for protective cover 5,
It is pulled open after position limiting structure, which completes limit, to be acted, then by buckle living, surrounded diameter of bore is buckled less than copper nut 4 by living
Outer circumference diameter, it is ensured that copper nut 4 can not be pierced by from living buckle.
Above-mentioned Anti-dismantling pipe connecting device is applied in air conditioner, is specifically used for the pipeline of indoor unit and outdoor unit
