Description

The connecting head structure of pipe joint
Technical field
The utility model relates to the technical field that pipeline connects, and is specially a kind of connecting head structure of pipe joint.
Background technique
In the field of industrial automation, pneumatic or the hydraulic pressure of usual employing is as the power of automation, the conveyance conduit connection completing liquid or gas is requisite parts in automatic field, different length needs to be connected with the pipeline of different bearing of trend, mutual pipeline connection is realized by pipe joint usually, pipe joint and external pipe Placement one end are normally by being threaded, because the size of the pipeline connected is not fixed, the other end adopts external pipe connecting head usually, realize the connection with the pipeline of different size, existing external pipe connecting head usually adopts with the Placement of pipe joint and welds, this Placement can effectively reduce the leakage of joint, if but during frequent replacing external pipe, the dismounting of external pipe joint is comparatively difficult.
Summary of the invention
In order to solve the problem, the utility model provides a kind of connecting head structure of pipe joint, while ensure that good joint sealing performance, can realize the replacing of different size pipe coupling simply, easily, improve the adaptability of pipe joint.
Its technological scheme is such: a kind of connecting head structure of pipe joint, it comprises pipe joint, described pipe joint connects external pipe joint, it is characterized in that, described external pipe joint connecting end is symmetrical arranged fluted, stage clip is respectively arranged with in described groove, spherical ball connects described external pipe joint by stage clip, the spherical groove coordinated with described spherical ball is provided with inside described pipe joint, the degree of depth of described spherical groove is less than spherical radius, be provided with step inside described pipe joint, described step arranges seal ring.
It is further characterized in that: described pipe joint comprises the first connecting head and the second connecting head, and described second connecting head is corner shape, and described first connecting head connects described external pipe joint, and described first connecting head is connected by tightening nut with between the second connecting head; Described tightening nut is stepped, described first connecting head is provided with the projection coordinated with described tightening nut ladder, and described second connecting head has screw thread with the first connecting head joint arranged outside, and described screw thread coordinates with described tightening nut; Described second connecting head is provided with outside thread; Described external pipe fitting end connects described seal ring, and the width of described external pipe fitting end and step is less than described seal ring thickness.
After adopting structure of the present utility model, external pipe joint connecting end is symmetrical arranged fluted, stage clip is respectively arranged with in groove, spherical ball connects external pipe joint by stage clip, the spherical groove coordinated with spherical ball is provided with inside pipe joint, the degree of depth of spherical groove is less than spherical radius, step is provided with inside pipe joint, step arranges seal ring, during external pipe joint connecting tube joint, in external pipe joint Inserting Tube joint, pipe joint inwall compressing ball, make in the smooth Inserting Tube joint of external pipe joint, after ball arrives spherical groove, ball is by the pressure press-in spherical groove of spring, achieve fixedly being connected together of external pipe joint and pipe joint, the sealing of external pipe joint and pipe joint is realized by the seal ring of end, when extracting external pipe joint, pipe joint inwall compressing ball, in ball retraction groove, successfully external pipe joint is extracted, while ensure that good joint sealing performance, can be simple, realize the replacing of different size pipe coupling easily, improve the adaptability of pipe joint.
Accompanying drawing explanation
Fig. 1 is the main sectional view of connecting head structure of the utility model pipe joint;
Fig. 2 is that A is to enlarged diagram.
Embodiment
See Fig. 1, Fig. 2, a kind of connecting head structure of pipe joint, it comprises pipe joint 1, pipe joint 1 comprises the first connecting head 2 and the second connecting head 3, be connected by tightening nut 4 between the first connecting head 2 with the second connecting head 3, tightening nut 4 is stepped, first connecting head 2 is provided with the projection 5 coordinated with tightening nut 4 ladder, second connecting head 3 there is screw thread 6 with the first connecting head 2 joint arranged outside, screw thread 6 coordinates with tightening nut 4, first connecting head 2 connects external pipe joint 7, external pipe joint 7 connecting end is symmetrical arranged fluted 8, stage clip 9 is respectively arranged with in groove 8, spherical ball 10 connects external pipe joint 7 by stage clip 9, the spherical groove 11 coordinated with spherical ball 10 is provided with inside first connecting head 2, the degree of depth of spherical groove 11 is less than spherical radius, step 12 is provided with inside first connecting head 2, step 12 is arranged seal ring 13, during external pipe joint connecting tube joint, external pipe joint inserts in the first connecting head, pipe joint inwall compressing ball, external pipe joint is made to insert in the first connecting head smoothly, after ball arrives spherical groove, ball is by the pressure press-in spherical groove of spring, achieve fixedly being connected together of external pipe joint and the first connecting head, the sealing of external pipe joint and the first connecting head is realized by the seal ring of end, when extracting external pipe joint, first connecting head inwall compressing ball, in ball retraction groove, successfully external pipe joint is extracted, while ensure that good joint sealing performance, can be simple, realize the replacing of different size pipe coupling easily, improve the adaptability of pipe joint.
Second connecting head 3, in corner shape, realizes the connection of pipeline different amount.
Second connecting head 3 is provided with outside thread 14, achieves the second connecting head and be connected with the simple of externally connected pipe.
External pipe joint 7 end 12 connects seal ring 13, and the width of external pipe joint 7 end and step 12 is less than seal ring 13 thickness, ensure that seal ring oppressed by external pipe joint 7, ensure that the sealing of external pipe joint and the first connecting head better.
