Practical effect.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of quick union.
The utility model is realized in this way a kind of quick union, including left interface, right interface and snap ring；The left side
The right end of interface is truncated cone-shaped protrusion；The truncated cone-shaped convex cross section is kidney-shaped；The left end of the right interface is truncated cone-shaped
Groove, one end shape for being equipped with truncated cone-shaped protrusion with left connector match, and there are also an annular grooves on the right side of rotary table connected in star, and the right side connects
The left end of mouth has peripherally and outwardly protruded out outward flange ring；The left and right connector is connected by snap ring, the left end inner surface of the snap ring
One end shape for being equipped with truncated cone-shaped protrusion with left connector matches, and right end has circumferentially inwardly protruded out inward flange ring；The inward flange ring
Internal diameter be equal to the outward flange ring outer diameter.
It is additionally provided with an annular groove on the truncated cone-shaped groove bottom wall, is equipped with sealing ring in annular groove；The right connector
Left end has peripherally and outwardly protruded out outward flange ring, is provided with external screw thread on the outward flange ring；
The truncated cone-shaped protrusion of the left connector is caught in the groove of right connector, and is connected by snap ring, the snap ring left end
Inner wall, which extends internally, annular chuck, and the right side of the annular chuck and the truncated cone-shaped protrusion left side of left connector offset,
The right end inner wall of snap ring is equipped with the inward flange ring that matches with right connector outward flange ring, inward flange ring be equipped with and outward flange
The internal screw thread that external screw thread on ring matches.
In order to facilitate worker operation, a positive stop lug boss is additionally provided on the right connector, the shape of positive stop lug boss, which can be processed, is
Hexagon.
Preferably, the snap ring material is consistent with left and right connector material.
Preferably, the sealing ring is rubber ring.
The utility model has the advantages that
1, the utility model is equipped with rubber ring in right connector, can promote the sealing effect of union.
2, left and right connector is connected using snap ring, and left and right connector can be rotated freely with respect to 360 ° when use, and personnel is facilitated to see
Examine the various detection devices installed on connector.
3, the utility model good connecting effect is not in easily to fall off, ensure that union using effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram after the utility model combines；
Fig. 3 is the perspective view of left connector in the utility model；
Drawing reference numeral explanation: raised 5. rotary table connected in stars 6. circle of right 3. snap ring of interface, 4. truncated cone-shaped of 1. left interface 2.
7. outward flange ring of connected in star, 8. inward flange ring
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Refering to fig. 1 and Fig. 2, a kind of quick union, including left interface 1, right interface 2 and snap ring 3；The left interface 1
Right end is truncated cone-shaped protrusion 4；The left end of the right interface 2 is rotary table connected in star 5, and the one of truncated cone-shaped protrusion 4 is equipped with left connector
Shape is held to match, there are also a circle connected in star 6, the left end of the right interface 2 has peripherally and outwardly protruded out outer on rotary table connected in star 5 right side
Flanged ring 7；The left and right connector 1,2 is connected by snap ring 3, and the left end inner surface of the snap ring 3 and left connector 1 are equipped with rotary table
One end shape of shape protrusion 4 matches, and right end has circumferentially inwardly protruded out inward flange ring 8；The internal diameter of the inward flange ring 8 is equal to described
The outer diameter of outward flange ring 7.
In the present embodiment, make encapsulation process filled with rubber ring in circle connected in star 6, the snap ring material connects with left and right
Head material is consistent.
A positive stop lug boss is additionally provided on the right connector 2, the shape of positive stop lug boss can be processed as hexagon.
Installation method:
Snap ring 3 is inserted in from the left side of left interface 1, resists the truncated cone-shaped protrusion 4 of left connector 1, and the truncated cone-shaped of left connector 1 is convex
It plays 4 to be pressed into the rotary table connected in star 5 of right interface 2, the outward flange ring 7 of right interface 2 is screwed into the inward flange ring 8 of connector, three is fast
Fast loose joint is fixed.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope.
