All Middle faces are round and smooth contact, and edge will not scratch pipe fitting inner wall during deformation, two groove centers away from setting cause this bodily form
Variable is suitable, to ensure good locking effect.
In a kind of above-mentioned pipe fitting cutting ferrule, the groove is arc groove or triangular groove.So processing side
Just, the deformation quantity of groove can conveniently be controlled by the processing of groove width and groove depth.
In a kind of above-mentioned pipe fitting cutting ferrule, the inner wall of the body has two circles in a ring and respectively close to this
The deformation groove at internal wall both ends, the width of the deformation groove are the body width of 0.15-0.25, and the groove depth of deformation groove is 0.4-
1.0mm, the body width that two deformation grooves are symmetrical arranged and the centre-to-centre spacing of two deformation grooves is 0.6-0.7.Ensureing that body construction is strong
On the premise of degree, for increase deformation groove to increase the deformation quantity of body, deformation groove also enhances locking of the inner body wall to connecting tube
Effect.
As another situation, in a kind of above-mentioned pipe fitting cutting ferrule, have one in the middle part of the inner wall of the body
The deformation groove of ring shape, the width of the deformation groove are the body width of 0.15-0.25, and the groove depth of deformation groove is 0.4-
1.0mm.On the premise of structural strength is ensured, deformation groove adds the deflection of body, and improves the lock of inner body wall
Tight effect.
In a kind of above-mentioned pipe fitting cutting ferrule, the deformation groove is arc groove or triangular groove.
Compared with prior art, this pipe fitting has collapsible and deformable leeway with cutting ferrule, and locking effect is good, sealing
Property it is good, and two sides and arc surface make it that the contact of the outer circumferential surface of body is good, prevent the outer circumferential surface scratching of the body of deformation
Pipe fitting inner wall, connection reliability are good.

Embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Embodiment 1
As depicted in figs. 1 and 2, this pipe fitting includes body 1 annular in shape, the two sides 2 of the outer circumferential surface of body 1 with cutting ferrule
For male cone (strobilus masculinus) or extrados, the outer circumferential surface of body 1 offers the groove 3 of twice in a ring, and groove 3 is arc groove or triangle ditch
Groove, two grooves 3 are respectively positioned at the interior along 1 width of body that the width of place and groove 3 is 0.12-0.22, groove 3 of corresponding side surface 2
Groove depth be 0.4-1.0mm, the two sides 2 of the outer circumferential surface of body 1 are extrados in the present embodiment, and groove 3 is arc groove, groove
3 width is 0.18 1 width of body, and the groove depth of groove 3 is 0.5mm.
Further describe in detail, in order to which contact is good, the arc surface 4 with a circle radially protruding in the middle part of the outer circumferential surface of body 1, two
Groove 3 is located at 4 both sides of arc surface respectively, and the centre-to-centre spacing of two grooves 3 is 1 width of body of 0.4-0.6, two grooves in the present embodiment
3 centre-to-centre spacing is 0.5 1 width of body.
This pipe fitting opens up groove 3 with being fastened on the outer circumferential surface of body 1, during locking, work of the body 1 in extruding
Have under contraction and deformable leeway, the tightening of groove 3 allows body 1 preferably to lock connecting tube, the groove width of groove 3
With the setting of groove depth, on the one hand can ensure good locking effect, on the other hand can effectively prevent because body 1 deform it is excessive
And lead to not restore, body 1 is also prevented from during being extruded by squeeze crack, the arc surface 4 of 1 outer circumferential surface of body and be outer
So that contact of the body 1 in extrusion process is good, the outer circumferential surface scratching pipe for the body 1 for preventing from deforming connects for the two sides 2 of cambered surface
Head inner wall.
