Described wedge-shaped cave 1014 is arranged on the Closed End of the union nut body 101 to the blind end of auxiliary nut 102
Side；It is preferred that the quantity in described wedge-shaped cave 1014 is at least 3, and the adapter spiral shell is divided equally in several wedge-shaped caves 1014
The circumference of the blind end of maternal body 101；Preferably, the Closed End of described auxiliary nut 102 is to the union nut body
The side of 101 blind end is provided with mounting hole 1024, and the mounting hole 1024 coordinates with the pin 107.
In another embodiment of the invention, connect refering to Figure 10 there is provided a kind of tamper-resistant union nut component comprising pipe
First 200 and above-described embodiment in union nut 100, the external screw thread of pipe joint 200 and the tapped blind hole 1011 of union nut 100
It is adapted.The method of its corresponding Anti-dismantling is included：When applying screw-down torque in auxiliary nut 102（In certain embodiments
It is rotate counterclockwise to turn clockwise, in other embodiment）, independent union nut body 101 and auxiliary nut 102
Two parts, the energy synchronous rotary under the drive of single direction rotation structure, it can be ensured that union nut body 101 leads to pipe joint 200
Threaded connection is crossed, so as to connect evaporator and connecting tube；But when applying in auxiliary nut 102 and unscrewing torque（In some implementations
It is rotate counterclockwise in example, is to turn clockwise in other embodiment）, auxiliary nut 102 can not butt tube nut body
101 apply moment of torsion, it is ensured that union nut body 101 is not released with pipe joint 200, it is ensured that union nut body 101 connects with pipe
Tight fit between first 200, plays the effect of Anti-dismantling.Specifically, when applying screw-down torque to auxiliary nut 102, pin
The cave bottom in the wedge-shaped cave 1014 of the blind end of 107 precession union nut body 101, due to the wedge of the blind end of union nut body 101
Shape cave 1014 is blocked by pin 107, now can be while stress, will take over spiral shell between auxiliary nut 102 and union nut body 101
Maternal body 101 is threadedly coupled with pipe joint 200, and when unscrewing torque to the application of auxiliary nut 102, pin 107 screws out adapter
The cave bottom in the wedge-shaped cave 1014 of the blind end of nut body 101, the smooth song in the wedge-shaped cave 1014 of the blind end of union nut body 101
There was only very small frictional force between face and pin 107, now the moment of torsion of auxiliary nut 102 is not transferred to union nut sheet
Body 101 and it is separated with pipe joint 200.
In another embodiment of the invention there is provided a kind of air conditioner, its evaporator and connecting tube use above-mentioned tamper
Unload the connection of formula union nut component.Tamper-resistant attachment structure can be achieved, secondary refrigerant leakage is prevented.
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for the present invention's
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
