Description

The connecting head structure of new tube joint
Technical field
The utility model relates to the technical field that pipeline connects, and is specially a kind of connecting head structure of new tube 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 new tube 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 new tube joint, it comprises pipe joint, described pipe joint connects external pipe joint, it is characterized in that, elongated slot is provided with inside described pipe joint, described elongated slot end is provided with the gradually narrow groove of width, be symmetrically arranged with outside described external pipe joint and coordinate and the projection corresponding with described groove with described elongated slot, described groove is provided with the bayonet socket with described male cooperation, be provided with step inside described pipe joint, described step arranges seal ring.
It is further characterized in that: described groove is provided with bayonet socket that is multiple and male cooperation; Described pipe joint comprises the first connecting head and the second connecting head, 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 corner shape; Described second connecting head is provided with outside thread; The minimum width of described groove and step is less than described seal ring thickness.
After adopting structure of the present utility model, elongated slot is provided with inside pipe joint, elongated slot end is provided with the gradually narrow groove of width, be symmetrically arranged with outside external pipe joint and coordinate and the projection corresponding with groove with elongated slot, step is provided with inside pipe joint, step arranges seal ring, during external pipe joint connecting tube joint, external pipe joint coordinates in Inserting Tube joint by protruding with the elongated slot inside pipe joint, after projection enters groove, rotate external pipe joint, projection snaps in bayonet socket, achieve the location of external pipe joint in pipe joint, the sealing of external pipe joint and pipe joint is realized by the seal ring of end, when extracting external pipe joint, press down external pipe joint, projection is separated with bayonet socket, rotating external pipe joint afterwards makes projection enter in elongated slot, 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 new tube joint;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
See Fig. 1, Fig. 2, a kind of connecting head structure of new tube 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, elongated slot 8 is provided with inside first connecting head 2, elongated slot 8 end is provided with the gradually narrow groove of width 9, be symmetrically arranged with outside external pipe joint 7 and coordinate and the projection 10 corresponding with groove 9 with elongated slot 8, groove 9 is provided with and protruding 10 bayonet sockets 11 coordinated, 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 coordinates in insertion first connecting head by protruding with the elongated slot inside the first connecting head, after projection enters groove, rotate external pipe joint, projection snaps in bayonet socket, achieve the location of external pipe joint in 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, press down external pipe joint, projection is separated with bayonet socket, rotating external pipe joint afterwards makes projection enter in elongated slot, 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.
Groove 9 is less than seal ring 13 thickness with the minimum width of step 10, ensure that seal ring oppressed by external pipe joint 7, ensure that the sealing of external pipe joint and the first connecting head better.
Groove 9 is provided with bayonet socket 11 that is multiple and male cooperation, realizes multi-stage sealed, ensure that the sealability of external pipe joint and pipe joint.
