To achieve the above object, the present invention proposes a kind of novel anti-loosening pipe joint connecting piece, including locking nut, pad
Circle, the locking nut is interior to be equipped with tapped through hole, and the tapped through hole lower end is equipped with nut circular slanting slope surface, the spiral shell
Female ring shape slope lower end is equipped with through-hole, and the tapped through hole, nut circular slanting slope surface are connected to through-hole, on the washer
Equipped with opening, the lower end of the washer is equipped with the washer annular ramp with the nut circular slanting slope surface cooperation in locking nut
Face.
Preferably, the angle of inclination phase at the angle of inclination and washer annular slope of the nut circular slanting slope surface
Together.
Preferably, the center of circle of the tapped through hole, nut circular slanting slope surface and through-hole is in same point.
Preferably, the washer inner ring surface is equipped with several anti-skid bulges.
Preferably, there is the washer toughness, the opening can be closed, open.
Preferably, the opening of the washer is in an open state in its natural state.
Preferably, when the opening of the washer is in nature opening state, the diameter of the washer is more than locking
The diameter of tapped through hole in nut.
Preferably, the opening of the washer is in the closure state, the diameter of the washer is slightly less than locking screw
The diameter of tapped through hole in mother, the diameter of the washer are more than the diameter of through-hole, the washer annular slope and spiral shell
Female ring shape slope engages.
Preferably, the locking nut is outer-hexagonal nut, the locking nut outer wall is equipped with outer-hexagonal bayonet.
Beneficial effects of the present invention：The present invention is compressed washer by nut, by being arranged washer on pipe fitting in spiral shell
When mother tightens, the opening of washer is tightened gradually, by washer by pipe fitting locking, makes the connection of pipe fitting and pipe fitting more closely,
By the way that anti-skid bulge is arranged in washer inner ring, the frictional force of washer and pipe fitting is increased, keeps pipe fitting not easily to fall off, ensures pipe fitting just
Often operation.
The feature and advantage of the present invention will be described in detail by embodiment combination attached drawing.

【Specific implementation mode】
Refering to fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of novel anti-loosening pipe joint connecting piece of the present invention, including locking nut 1,
Washer 2, the locking nut 1 is interior to be equipped with tapped through hole 11, and 11 lower end of tapped through hole is equipped with nut circular slanting slope surface
12,12 lower end of nut circular slanting slope surface is equipped with through-hole 13, the tapped through hole 11, nut circular slanting slope surface 12 and logical
Hole 13 is connected to, and the washer 2 is equipped with opening 21, and the lower end of the washer 2 is equipped with and the nut annular in locking nut 1
The washer annular slope 22 that slope 12 coordinates, angle of inclination and the washer annular ramp of the nut circular slanting slope surface 12
The angle of inclination in face 22 is identical, the center of circle of the tapped through hole 11, nut circular slanting slope surface 12 and through-hole 13 in same point,
2 inner ring surface of washer is equipped with several anti-skid bulges 23, and there is the washer 2 toughness, the opening 21 can be closed, beat
It opens, the opening 21 of the washer 2 is in an open state in its natural state, and the opening 21 of the washer 2 is in nature opening
When state, the diameter of the washer 2 is more than the diameter of the tapped through hole 11 in locking nut 1, the opening 21 of the washer 2
In the closure state, the diameter of the washer 2 is slightly less than the diameter of the tapped through hole 11 in locking nut 1, the pad
