Specific implementation mode
The specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figs. 1-12, the present invention is a kind of non-dismountable and anti-loosening tube joint assembly.
Air conditioner connecting tube pipe fitting is vibrated or other environment influence the loosening generated and people in order to solve by the present invention
For the leakage for the combustible refrigerant that dismounting occurs, provides a kind of non-dismountable and prevents the tube joint assembly loosened comprising
Straight connector 1, pipe nut 2, retaining set 3, shrapnel 4, baffle ring 5, clamp spring 6 with bell-mouthed connecting tube 7 and welding connecting tube 8.
Straight connector 1 is threadedly coupled with the Internal Pipe Thread 22 of pipe nut 2, is provided on the pipe nut 2 and is hooked slot 21, and retaining set 3 is logical
It crosses retaining hook slot 31 to be set on the hook slot 21 of pipe nut 2, shrapnel 4 and hook slot 21 and retaining hook the space that slot 31 is formed and be affixed
It closes, pipe nut 2 rotates clockwise, and pipe nut 2 is locked with straight connector 1；Engaging has clamp spring 6 on the annular groove 25 of pipe nut 2,
5 side of baffle ring is fitted on clamp spring 6, and the other side is fitted on the baffle ring step 24 of pipe nut 2, withholds part shrapnel 4.
The 1 outer circle peripheral surface one end of straight connector is prismatic surface 11, and the other end is external pipe thread 12, in external pipe thread 12
Open slot 13 is provided on busbar, the end of external pipe thread 12 is cone table 14；Endoporus is to be arranged with weldering on ladder round tube hole 15
Take over 8 in succession.The pipe nut 2, endoporus one end have with 1 external screw thread of straight connector, 12 matched Internal Pipe Thread 22, it is another
There are concave cone table top 23 corresponding with the cone table 14 in straight connector 1 and connecting tube perforation 26 in end；The peripheral surface of pipe nut 2
For ladder circle cylinder, middle part is a flange, and one end on external cylindrical surface is provided with the hook slot 21 that one end is closed, is not sealed
There is a stair-step 24 in the one end closed, has an annular groove 25 close to stair-step.Retaining set 3, endoporus with it is described
The cylindrical surface that pipe nut 2 is provided with hook slot 21 matches, and is additionally provided on endoporus periphery and 21 phase of hook slot on pipe nut 2
Corresponding retaining hooks slot 31；The peripheral surface of retaining set 3 is prismatic surface 32.It is provided on the outer circumference surface for hooking slot 21 in pipe nut 2
Retaining set 3 is put on, keeps 2 outer circle of pipe nut hook slot 21 corresponding with retaining set 3 endoporus retainings hook slot 31, is hooked in hook slot 21 and retaining
Shrapnel 4 is loaded onto in 31 space of slot, and baffle ring 5 is loaded onto on the step 24 of 4 end face of shrapnel on pipe nut 2, close to baffle ring on pipe nut 2
Clamp spring 6 is loaded onto in 5 annular groove 25.When the prismatic surface 32 on the retaining set 3 applies screw-down torque, shrapnel 4 blocks
3 inner ring retainings are covered in retaining to hook on slot 31, pipe nut 2 is driven to rotate, and pipe nut 2 is locked with straight connector 1；Stop when in described
When application reversely unscrews torque on the prismatic surface 32 of drill drift 3, retaining covers 3 inner rings and is slided on shrapnel 4, cannot drive pipe nut 2
Rotation cannot be such that the pipe nut 2 of locking is disengaged with straight connector 1.After pipe nut 2 and straight connector 1 are locked, straight connector 1
External pipe thread 12 on open slot 13 will prevent locking pipe fitting loosen.

More than, 13 bottom of open slot to bottom diameter position can prevent the spiral shell locked after such external pipe thread and Internal Pipe Thread locking
Line loosens.
Further, the hook slot 21 being arranged on 2 exterior circular column of pipe nut is 3 or 3 or more, and is uniformly distributed；
It is corresponding with the hook slot 21 on 2 exterior circular column of pipe nut that retaining covers the retaining hook slot 31 on 3 inner rings；4 numbers of shrapnel and hook slot 21
Number is identical.In this way, when applying screw-down torque to retaining set 3, it can guarantee that uniform force, stabilization, coupling mechanism force are big.
Further, the shrapnel 4 is angular structure, and arc transition between two sides.
Further, the material of the shrapnel 4 is high duty metal elastic material.
Further, it is hexagon or other prismatic that the retaining, which covers 3 peripheral surfaces,.
Further, the straight connector 1 and pipe nut 2 are metal material.
The bell-mouthed connecting tube 7 of band and welding connecting tube 8 drawn from air conditioner room unit and outdoor unit, welding connecting tube
8 are welded on the connecting tube welding hole 15 of the straight connector 1, and another connecting tube 7 with conical horn mouth passes through pipe
Perforation 26, is fitted in 7 peripheral surface of bell-mouthed connecting tube on 2 endoporus concave cone table top 23 of pipe nut in nut 2, to retaining set 3
Apply screw-down torque, tightens pipe nut 2 and straight connector 1,14 top pressure of circular cone table top of the external pipe thread end in straight connector 1
Connecting tube horn mouth medial surface realizes that air conditioner room unit is connected with the locking of outdoor unit connecting tube.Connecting tube joint lock is next,
The open slot 13 of external pipe thread 12 in straight connector 1 can prevent straight connector 1 and the threaded connection of pipe nut 2 from loosening；Connection
After pipe joint locking, when reversely unscrewing torque to 3 application of retaining set, retaining covers 3 endoporus and hooks the shrapnel 4 in slot 21 in pipe nut
Upper sliding cannot drive pipe nut 2 to rotate, to reach the non-removable purpose of straight connector 1 and pipe nut 2.It prevents
Pipe joint screw thread loosens, and prevents pipe fitting from occurring accidentally to dismantle, avoids air conditioner combustible refrigerant from leaking, ensure that the life of user
Life safety.
It is above the preferred embodiment of the present invention, protection scope of the present invention is not limited, for people in the art
The deformation and improvement that member's mentality of designing according to the present invention is made, all should be considered as within protection scope of the present invention.
