This utility model purpose is: for the problems referred to above, it is provided that a kind of plastic tube joint for sealing connecting, to ensure
Connective stability between plasticity pipeline and sealing.
The technical solution of the utility model is: a kind of plastic tube joint for sealing connecting, for the connection of plasticity pipeline,
It includes the annular outer cover with opening, the fastening bolt being located at this annular outer cover opening part, is arranged in this ring
Sealing ring in shape shell, the axial two ends of described annular outer cover form radially inwardly projecting circle respectively
Arc-shaped clamp, the radially inner cambered surface of described circular arc clip is gathered and forms latch.
This utility model, on the basis of technique scheme, also includes following preferred version:
The circular arc forming five axially spaced-apart distributions in the radially inner cambered surface of described circular arc clip is convex
Rib, if all offering spaced apart along this circular arc shaped rib length direction on each described circular arc shaped rib
A dry arcuate groove, thus form described latch at two arcuate grooves of arbitrary neighborhood.
The axial cross section of described circular arc shaped rib is triangle.
The axial both ends of the surface of described sealing ring abut with the axial inner ends face of described two circular arc clips.
The seal lip ring of radially convex is formed on the inwall of described sealing ring.
Described fastening bolt has two, and is hexagon socket head cap screw.
Described circular arc clip is copper.
The utility model has the advantages that: owing to this pipe joint of this utility model is at the axial two ends of annular outer cover
Form radially inwardly projecting circular arc clip respectively, and in the radially inner cambered surface of circular arc clip
Gathering and form latch, it is when connecting plasticity pipeline, and latch can consolidate the outer wall of promptly pipeline, prevents pipe
Joint skids on pipeline outer wall, it is ensured that the connective stability between plasticity pipeline and sealing.And, band
The circular arc clip having latch is structure as a whole with annular outer cover, when reality is applied, it is not necessary to worry with card
The circular arc clip of tooth can move relative to annular outer cover, and structural stability is high.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of this utility model embodiment, in embodiment being described below
The required accompanying drawing used is briefly described, and the accompanying drawing in describing below is only some enforcements of the present invention
Example, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to root
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the three-dimensional structure diagram of plastic tube joint for sealing connecting in this utility model embodiment；
Fig. 2 is the A portion enlarged drawing of Fig. 1；
Wherein: 1-annular outer cover, 1a-opening, 2-fastening bolt, 3-sealing ring, 4-circular arc clip, 4a-
Latch, 41-circular arc shaped rib, 42-arcuate groove.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are to use
It is not limited to limit scope of the present utility model in explanation this utility model.The implementation condition used in embodiment
Can do adjustment further according to the condition of concrete producer, not marked implementation condition is usually in normal experiment
Condition.
Fig. 1 shows of this utility model this plastic tube joint for sealing connecting (hereinafter referred to as pipe joint)
Specific embodiment, identical with conventional pipelines joint, it also includes the annular outer cover 1 (tool of band opening 1a
Body is, the periphery of annular outer cover 1 axially disconnects and forms described opening 1a), be located at this annular outer cover and open
Fastening bolt 2 at Kou, the sealing ring 3 being arranged in this annular outer cover.Wherein fastening bolt 2 has two,
And it is hexagon socket head cap screw.During actual application, this pipe joint is set in the joint of two pipelines, by six
Angle spanner rotates described fastening bolt 2 and makes the gap of annular outer cover 1 opening part diminish, and then makes outside annular
Shell 1 forms radially inner chucking power to sealing ring 3, and shell is fastened, and and then makes the inwall of sealing ring
Shrink to clamp the outer wall realization sealing placing two pipelines therein.
The key improvements of the present embodiment is: the axial two ends of described annular outer cover 1 form radially respectively
Inwardly projecting circular arc clip 4 (circular arc clip 4 and annular outer cover 1 are structure as a whole), and circular arc
Gather in the radially inner cambered surface of shape clip 4 and form latch 4a.The aperture position of circular arc clip 4 and ring
The aperture position of shape shell 1 is corresponding.In this example, this circular arc clip 4 is copper.
Owing to the annular outer cover of this pipe joint of this enforcement have employed said structure, it is when connecting plasticity pipeline,
Latch 4a can consolidate the outer wall of promptly pipeline, prevents pipe joint from skidding on pipeline outer wall, it is ensured that plasticity pipeline
Between connective stability and sealing.And, with circular arc clip 4 and the annular outer cover 1 of latch 4a
It is structure as a whole, when reality is applied, it is not necessary to worry that the circular arc clip 4 with latch 4a can be relative to ring
Shape shell 1 moves.
With reference to shown in Fig. 2, above-mentioned latch 4a is obtained by following version: described circular arc clip
The circular arc shaped rib 41 of five axially spaced-apart distributions, each described circle is formed in the radially inner cambered surface of 4
All offer along this circular arc shaped rib length direction several arcuate grooves 42 spaced apart on arc fin 41,
Thus form described latch 4a at two arcuate grooves 42 of arbitrary neighborhood.And described circular arc shaped rib 41
Axial cross section is triangle.
And, the axial inner ends face of the axial both ends of the surface of described sealing ring 3 and described two circular arc clips 4 is supported
Connect, so can prevent sealing ring 3 from moving axially in the enclosure, it is ensured that the sealing between pipe joint and pipeline outer wall
Property.And on the inwall of sealing ring 3, form several seal lip rings 3a of radially convex, with further
Improve the sealing between this pipe joint and pipeline outer wall.
