In figure, joint body 1, nut 2, C-shaped ring 3, spool slot 4, external screw thread 5, pressure ring 6, spool 7.
Specific embodiment
The technical solution of the utility model is described in detail with reference to the accompanying drawing:
A kind of metal spool quick coupling as shown in Figs. 1-5, including joint body 1, nut 2 and C-shaped ring 3.Wherein connect
Head 1 both ends inner wall of ontology is equipped with spool slot 4, and spool slot 4 is adapted to 7 size of spool, and spool 7 is pressed into spool slot 4 after being inserted into connector
It is interior.The spool slot 4 of 1 two sides of joint body can be spaced apart or connects and be integrated.
What is illustrated in advance is position term " inside " " outside " used in the utility model description, is in basic connector
Heart line defines, rather than singly refers to the inner or outer of a certain separate part.
1 both ends outer wall of joint body is equipped with 5 structure of external screw thread, and the part of setting external screw thread 5 is cone, the cone
Outsole is in inside, and handle is in joint body end surface side.
Screw thread in the utility model nut 2 is the matched taper of conical end with joint body 1.The utility model
The bevel angle α of middle pyramidal structure is less than 3 degree.Preferably, the bevel angle of nut 2 is less than the inclined-plane of 1 cone of joint body
Angle, this angle difference is very small, so that the process that nut is tightened on external screw thread is gradually to become tight.
C-shaped ring 3 is mounted on spool 7, and C-shaped ring 3 is closely sleeved on spool 7, is matched with C-shaped ring structure, outside nut 2
Side is equipped with pressure ring 6, and the gear of pressure ring 6 is in 3 outside of C-shaped ring.Since 2 inner cavity of nut is taper, C-shaped ring 3 is closer to pressure ring 6, C-shaped ring 3
Opening with regard to smaller.
As shown in figure 4, this quick coupling is when in use, nut 2, C-shaped ring 3 first cover on metal spool 7, then by metal
Spool 7 is inserted into spool slot 4；Then nut 2 is shifted on external screw thread, while C-shaped ring 3 pushes joint body end face to by nut 2
Direction；During tightening nut 2, there is the limit of joint body on the inside of C-shaped ring, outside pressure ring 6 is constantly close.C-shaped ring 3
Accommodation space is gradually reduced to which diameter is shunk, increasing to the cohesive force of pipeline 7, to make spool fix, until C-shaped ring
Diameter can not be shunk again, and nut twists and is affixed to position.
