In the circumferential clasp groove of elastic opening snap ring.Elastic opening snap ring top spreading is inserted in circumferential clasp when so being inserted by pipeline
Groove, wedging when being pulled out by pipeline and can not extract.This kind of pipeline latch fitting needs to set gap at pipeline and latch fitting opening,
When pipeline needs dismounting to pull away, to be inserted into ejection snap ring at snap ring for object (instrument) so that snap ring is not with pipeline
Move and towards conical surface movement, prevent locking and then pipeline can be extracted.Pipeline of the prior art and latch fitting open-ended gaps
Presence so that the combination of pipe fitting and pipeline is unstable, and pipeline easily rocks.
Utility model content
Regarding to the issue above, the utility model aims to provide and a kind of facilitate the dismounting of pipeline and greatly improve pipeline and latch fitting
Between stability pipeline latch fitting.
To realize the technical purpose, scheme of the present utility model is：A kind of pipeline latch fitting, for the pipeline reality of locked insertion
Existing pipeline connection, the latch fitting is hollow structure, is provided with to place the annular seal groove of sealing ring on its madial wall, and use
To place the draw-in groove of snap ring；The openend internal diameter of the latch fitting matches with the outer diameter tube that need to be inserted, and latch fitting inwall is opened in it
It is cone structure at mouth end to draw-in groove, the internal diameter of openend is less than draw-in groove diameter；It is provided with to stretch into thing on the openend
Part withstands the arc port of snap ring.
Preferably, the arc port is two, in being symmetrically set.
Preferably, the latch fitting is integrated cast metal construction, the pipe thickness of the latch fitting is 1.0~2.5mm.
Preferably, the radian of the arc port is 10~80 °.
Preferably, being additionally provided with connection bump on madial wall in the middle part of the latch fitting, the connection bump is located at annular
Seal groove inner side.
The beneficial effects of the utility model are, by the structure matched using pipeline tapping end internal diameter and outer diameter tube,
Can enable that pipe fitting holds pipeline very well so that pipeline is difficult to rock, and being arranged on for arc port do not influence anchor ear effect
In the case of insertion instrument can be facilitated to withstand snap ring, to extract the pipeline being connected with latch fitting；Further, latch fitting is used
Die cast is obtained so that the more solid practicality of pipeline latch fitting, improves anchor ear intensity.

Specific embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-5, specific embodiment described in the utility model is a kind of pipeline latch fitting, for the pipe of locked insertion
Road realizes that pipeline is connected, and the latch fitting 1 is hollow structure, is provided with to place the ring packing of sealing ring 7 on its madial wall
Groove 2, and it is used to place the draw-in groove 4 of snap ring 8；The internal diameter of openend 5 of the latch fitting 1 matches with the external diameter of pipeline 9 that need to be inserted, lock
The inwall of part 1 is cone structure at its openend 5 to draw-in groove 4, and the internal diameter of openend 5 is less than the diameter of draw-in groove 4；The openend 5
On be provided with to stretch into the arc port 6 that object withstands snap ring.The pipeline latch fitting of the design can have linkage function for one end
Latch fitting, the other end is straight-through or bending pipe structure；The pipeline latch fitting of the design can also have linkage function for two ends
Latch fitting, straight-through or bend pipe structure.Wherein Fig. 1,3 are the pipeline latch fitting of dual openings end bypass structure.
For installing/dismounting, the arc port 6 is two, in being symmetrically set.Being symmetrical arranged arc port can be conveniently
Insertion instrument, can preferably be used for fixing clasp, facilitate stress, the pipeline that extraction is connected with pipeline latch fitting；While openend
Reserved part is wider, can be very good to fix pipeline.It is symmetrical arranged the more convenient instrument insertion of arc port, more preferable fixing card
Ring.Arc port can be two, or three, or more, as long as facilitate insertion instrument fixing clasp.
In order that obtaining latch fitting stability more preferably, the latch fitting 1 is integrated cast metal construction, the thickness of pipe wall of the latch fitting 1
It is 1.0~2.5mm to spend.Existing latch fitting is generally obtained using die cast, and the material for using is relatively thin, less stable, and this
Body is gone using the latch fitting of cast metal construction, and latch fitting has certain thickness so that the more solid practicality of pipeline latch fitting, improves anchor ear
Intensity.
The radian of the arc port 6 is 10~80 °.The larger arc port of radian is more convenient stress, is conducive to extracting and pipe
The pipeline that road latch fitting is connected.
In order that the body that must be connected by latch fitting connects even closer, it is additionally provided with the madial wall in the middle part of the latch fitting
Connection bump, the connection bump is located at annular seal groove inner side.On the one hand connection bump can play position-limiting action to body,
Another aspect connection bump can form better seal structure with the sealing ring in annular seal groove.
When using, the sealing ring 7 of quality of rubber materials is placed in the annular seal groove 2 of latch fitting 1, from the opening of the one end of latch fitting 1
End 5 be put into it is jaggy elasticity snap rings 8, then pipeline 9 is inserted in latch fitting 1 through snap ring 8, the front end of pipeline 9 be connected
Raised 3 are in contact fixation, and the front center of pipeline 9 is sealed by sealing ring 7, and sealing ring forms a good sealing with connection bump
Structure；Spill tube seat 10 is provided with the pipeline 9, pipeline is held tightly by the snap ring 8 of spill tube seat 10 is waled, connection is completed；
Due to the structure that openend internal diameter and outer diameter tube match, can enable that pipe fitting holds pipeline very well so that pipeline is not
Easily rock.Simultaneously because the diameter of openend 5 is less than the diameter of draw-in groove 4, when pipeline 9 is outwards extracted, snap ring 8 can be held tightly so as to wale pipe
Road, because the diameter of openend 5 is small, openend is blocked snap ring is spacing, and snap ring cannot be expanded cannot also be extracted, and finally causes pipeline
Cannot be pulled out.
During dismounting, it is inserted into instrument in arc port 6 and fixes the snap ring of elasticity, because snap ring is jagged, the Vertical Square of snap ring 8
To pull-out tube road 9 after fixation, snap ring 8 can open amplification, and draw-in groove 4 is relatively large in diameter, and the stretching, extension that can meet snap ring is opened.Pipeline
9 can just separate with snap ring 8, it is taken apart from latch fitting 1.
The above, preferred embodiment only of the present utility model is not used to limit the utility model, every according to this
Any trickle amendment, equivalent and improvement that the technical spirit of utility model is made to above example, should be included in this
Within the protection domain of utility model technical scheme.
