Be formed with the second block face 83 between low-lying end 81, described second block face 83 in described pipe joint 50 with described
When union nut 60 reversely screws, backstop is on the second stop surface 92 of described gear piece 94.
So, when pipe joint 50 and union nut 60 are when sealed to close to each other, described first chisel teeth
High-end the 72 of 70 slip over first sidepiece 95 at the first place, side of described gear piece 94 and described second wedge
After second sidepiece 96 at the second place, side that high-end the 82 of shape tooth 80 slip over described gear piece 94, gear piece 94
Recover elastic deformation so that the between the first stop surface 91 of gear piece 94 with adjacent 2 first chisel teeths 70
One block face 73 is facing, between the second stop surface 92 of gear piece 94 with adjacent 2 second chisel teeths 80
Two block faces 83 are facing, when operator's maloperation, when reversely screwing pipe joint 50 with union nut 60, and tooth
Sheet 94 first stop surface 91 can backstop on the first block face 73, the second stop surface 92 backstop of gear piece 94
On the second block face 83, even if operator is the biggest, gear piece 94 is at the first block face 73 and the second block face
The common effect of 83 is lower to be reversed, to increase the dismounting difficulty of dismounting pipe joint 50 and union nut 60, it is to avoid
There is the thing of dismounting by mistake, it is to avoid the coolant leakage of air-conditioner, it is ensured that the life security of user.
Please refer to Fig. 4 to Fig. 7, described union nut 60 also includes being connected to described second outer-hexagonal section
The Taper Pipe section 63 of 61.The end 21 of described first connecting tube 20 is provided with the widest connecting portion of opening 22.
Described connecting portion 22 is folded between the end of described external thread section 52 and described Taper Pipe section 63.
One first conical surface 64 it is formed with in described Taper Pipe section 63.The end of described external thread section 52 is formed with
Two conical surfaces 54.The connecting portion 22 of described first connecting tube 20 is folded in described first conical surface 64 and described the
Between two conical surfaces 54.It is to be appreciated that between the connecting portion 22 of the first connecting tube 20 and Taper Pipe section 63 or
(figure is not can to arrange sealing ring between connecting portion 22 and the end of external thread section 52 of the first connecting tube 20
Show), to increase the sealing between three.
In the installation process of above-mentioned Anti-dismantling pipe connecting device 10, the one end 31 of the second connecting tube 30 is welded in
In described pipe joint 50, the first connecting tube 20 is penetrated to union nut 60 by the second outer-hexagonal section 61,
And the connecting portion 22 of the first connecting tube 20 is placed in the Taper Pipe section 63 of union nut 60.Then, by elasticity
Packing ring 90 is inserted in the external thread section 52 of pipe joint 50, re-uses screwing tool and is respectively acting on pipe joint 50
The first outer-hexagonal section 51 and the second outer-hexagonal section 61 of union nut 60 rotate forward (dextrorotation
Turn), external thread section 52 is locked in union nut 60, until first stop surface on elastic washer 90 two sides
91 and second stop surface 92 respectively with the first chisel teeth 70, second wedge of union nut 60 of pipe joint 50
Shape tooth 80 phase wedge shape is connected, due to the existence of elastic washer 90, make pipe joint 50 and union nut 60 it
Between cooperatively form sealing.Pipe joint 50 and union nut 60 just cannot be dismantled after once installing, it is to avoid send out
The thing of raw dismounting by mistake, it is to avoid the coolant leakage of air-conditioner, it is ensured that the life of user and property safety.
