Description
Technical field
The utility model relates to technical field of pipeline connection, and in particular to a kind of pipeline connecting assemble.
Background technique
It is existing that generally there is female screw connection or external screw thread connector to connecting pipe end, by different pipe fittings it
Between female screw connection be mutually threadedly coupled with external screw thread connector, to guarantee the leakproofness of connection, however this kind of mode
When upper and lower conduit volume weight is larger, just it is difficult to be rotatablely connected.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of pipeline connecting assemble:
A kind of pipeline connecting assemble, including being threadedly coupled the upper binding head of extraneous female screw connection, being threadedly coupled the external world
The lower union joint of external screw thread connector, the internal screw thread sealing ring for being socketed upper binding head and lower union joint,
The upper binding head lower end is equipped with circumferentially distributed and axially extending multiple hook items, and the hook end is equipped with
Interior curved hook, hook item outside are equipped with the rubber tube head of sealing cladding hook item；Rubber tube head upper end is fixedly connected
Connector lower end outer rim, rubber tube head lower end inner wall is equipped with the internal projecting ring outwardly protruded and its underpart outer rim is equipped with the first external screw thread
Portion；
The lower union joint successively includes constituting the detent head and internal projecting ring being clasped with multiple hook items from top to bottom
Constitute the sealed annular snap groove portion snapped connection, the second external thread part, second external thread part and the first of rubber tube head
External thread part forms external screw thread combination section, and the external screw thread combination section and internal screw thread sealing ring constitute sealed threaded connection.
Upper binding head is threadedly coupled two female screw connections to connecting tube with lower union joint respectively and external screw thread connects
Connector, at this time rotation are vertically connected with head and after rotation is fixedly mounted, then can plug each other so that detent without rotation to connecting tube
Head with hook item, internal projecting ring and annular snap groove portion mutually fix by detent, the former is mainly used for upper binding head and lower union joint
Mutual detent is fixed, and the latter is mainly used for sealing, after the installation is completed, then this is outer positioned at the internal screw thread sealing ring edge of lower union joint
Screw thread combination section is rotated up to the connection transitional region of covering upper binding head and lower union joint, to further complete pipeline
Seal operation.
Preferably, there are four the hook item is set, it is easily installed detent.
The utility model has the following beneficial effects: two pipe fittings can be completed without being threadedly coupled directly buckle in this product
Sealing install fix, reduce the use of components, enormously simplify installation steps.
Detailed description of the invention
Attached drawing 1 is the diagrammatic cross-section of upper binding head.
Attached drawing 2 is the diagrammatic cross-section of lower union joint and internal screw thread sealing ring.
Attached drawing 3 is the assembling section of embodiment.
1 upper binding head, 2 lower union joints, 3 internal screw thread sealing rings, 4 hook items, 5 rubber tube heads, 6 first external thread parts, in 7
Bulge loop, 8 detent heads, 9 annular snap groove portions, 10 second external thread parts.
Specific embodiment
The utility model is further described in 1-3 and embodiment with reference to the accompanying drawing.
Embodiment: a kind of pipeline connecting assemble, upper binding head 1, screw thread including being threadedly coupled extraneous female screw connection
It connects the lower union joint 2 of extraneous external screw thread connector, be socketed the internal screw thread sealing ring 3 of upper binding head 1 and lower union joint 2,
1 lower end of upper binding head is equipped with four circumferentially distributed and axially extending hook items 4,4 end of hook item
Equipped with interior curved hook, the rubber tube head 5 of sealing cladding hook item 4 is equipped on the outside of hook item 4；5 upper end of rubber tube head is solid
Surely 1 lower end outer rim of upper binding head is connected, 5 lower end inner wall of rubber tube head is equipped with the internal projecting ring 7 outwardly protruded and its underpart outer rim is set
There is the first external thread part 6；
The lower union joint 2 successively include from top to bottom constituted with four hook items 4 the detent head 8 being clasped, with it is interior
Bulge loop 7 constitutes the sealed annular snap groove portion 9 snapped connection, the second external thread part 10, second external thread part 10 and rubber
First external thread part 6 of tube head 5 forms external screw thread combination section, and the external screw thread combination section and internal screw thread sealing ring 3, which are constituted, to be sealed
Formula is threadedly coupled.
Upper binding head 1 is threadedly coupled two female screw connections and external screw thread to connecting tube with lower union joint 2 respectively
Connector, rotation at this time be vertically connected with first 2 can without rotation to connecting tube, after rotation is fixedly mounted, then plug each other so that
Detent head 8 with hook item 4, internal projecting ring 7 and annular snap groove portion 9 mutually fix by detent, the former is mainly used for upper binding head 1 under
The mutual detent of connector 2 is fixed, and the latter is mainly used for sealing, after the installation is completed, then by this positioned at the internal screw thread of lower union joint 2
Sealing ring 3 is rotated up along external screw thread combination section to the connection transitional region of covering upper binding head 1 and lower union joint 2, thus into
The seal operation of one step completion pipeline.Obviously, the above embodiments of the present invention is merely to illustrate that the utility model institute
The citing of work, and not limitations of the embodiments of the present invention.For those of ordinary skill in the art, exist
Other various forms of variations or variation can also be made on the basis of above description.There is no need and unable to all implementation
Mode gives poor example.And these connotation changes and variations that derived from for belonging to the utility model still belong to
In the protection scope of the utility model.
