Shape is even damaged, the final sealing property for influenceing bite type high-pressure oil pipe joint.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of bite type high-pressure oil pipe joint, nut can be avoided to twist
When tight, cause cutting ferrule deformation or even damage.
In order to achieve the above object, the utility model uses following technical scheme：
A kind of bite type high-pressure oil pipe joint, including fittings body, be threadedly coupled with the fittings body nut, be arranged at institute
The cutting ferrule between fittings body and the nut is stated, connecting tube is inserted in the fittings body, and passes through the nut and the card
Set is fixed；
A connecting portion is provided with the connector, the connecting portion lateral wall is connected with the nut thread, the company
Socket part madial wall is connected with the cutting ferrule and joint face is in inclined-plane, and the nut bottom, the company are pressed close in the connecting portion end
The first sealing tooth is provided with the inclined-plane of socket part, the second sealing tooth, and first sealing are provided with the inclined-plane of the cutting ferrule
Tooth and the second sealing tooth match.
A kind of above-mentioned bite type high-pressure oil pipe joint, wherein, set between the cutting ferrule end and the connecting portion bottom
It is equipped with the first sealing ring.
A kind of above-mentioned bite type high-pressure oil pipe joint, wherein, set between the connecting portion end and the nut bottom
It is equipped with the second sealing ring.
A kind of above-mentioned bite type high-pressure oil pipe joint, wherein, the crown of the first sealing tooth is towards the connecting portion
Bottom direction.
A kind of above-mentioned bite type high-pressure oil pipe joint, wherein, the crown of the second sealing tooth is towards the connecting portion
End direction.
Using above technical scheme, following beneficial effect can be reached：
Nut bottom is pressed close in the utility model connecting portion end, in the absence of very big gap, cutting ferrule can be avoided to deform, together
When, the first sealing ring is provided between cutting ferrule end and connecting portion bottom, when nut is tightened, cutting ferrule and the first sealing
Circle offsets, and operating personnel can be clearly felt that, and stops continuing to tighten nut, prevents cutting ferrule from deforming, while can avoid
The hardness touching of cutting ferrule and fittings body, it can equally avoid the deformation of cutting ferrule or even damage.
Brief description of the drawings
Fig. 1 is a kind of structural representation of bite type high-pressure oil pipe joint of the utility model；
Fig. 2 is A portions enlarged drawing in the utility model Fig. 1.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as of the present utility model
Limit.
As depicted in figs. 1 and 2, a kind of bite type high-pressure oil pipe joint, including fittings body 1, be threadedly coupled with fittings body 1
Nut 2, the cutting ferrule 3 being arranged between fittings body 1 and nut 2, connecting tube 100 are inserted in fittings body 1, and pass through the He of nut 2
Cutting ferrule 3 is fixed；A connecting portion 11 is provided with connector 1, the lateral wall of connecting portion 11 is threadedly coupled with nut 2, in connecting portion 11
Side wall is connected with cutting ferrule 3 and joint face is in inclined-plane, and the end of connecting portion 11 is pressed close to the bottom of nut 2, set on the inclined-plane of connecting portion 11
There is the first sealing tooth 12, the second sealing tooth 13 is provided with the inclined-plane of cutting ferrule 3, and the first sealing tooth 12 and second seals the phase of tooth 13
Matching.
Preferably, the crown of the first sealing tooth 12 seals the crown direction of tooth 13 towards the bottom direction of connecting portion 11, second
The end direction of connecting portion 11.
In the preferable embodiment of the utility model, it is close between the end of cutting ferrule 3 and the bottom of connecting portion 11 to be provided with first
Seal 4, when nut 2 is tightened, cutting ferrule 3 is constantly pushed into the bottom of connecting portion 11 by nut 2, until cutting ferrule 3 and first close
Seal 4 offsets, and operating personnel can be clearly felt that, and stops continuing to tighten nut 2, prevents cutting ferrule 3 from deforming, while can also
The liquid in connecting tube 100 is avoided to be let out between the joint face of cutting ferrule 3 and connecting portion 11.
In the preferable embodiment of the utility model, the second sealing is provided between the end of connecting portion 11 and the bottom of nut 2
Circle 5, the liquid leakage that can avoid reaching the bottom of nut 2 are gone out.
When specific installation, connecting tube 100 is inserted into fittings body 1, until the bottom of connecting portion 11, then successively
The first sealing ring 4, cutting ferrule 3, the second sealing ring 5 are inserted in, nut 2 is finally inserted in, then constantly tightens nut 2, now, nut
2 constantly promote cutting ferrule 3 to enter fittings body 1, until cutting ferrule 3 is entered at the first sealing ring 4 of the bottom of connecting portion 11, first is close
Seal 4 is preferably elastic rubber ring, and after being offseted with cutting ferrule 3, stopping continues to tighten nut, and now the first sealing ring 4 gives card
The power of 3 one bounce-backs are covered, promote cutting ferrule 3 to return, simultaneously as the first sealing crown of tooth 12 is towards the bottom direction of connecting portion 11,
The crown of second sealing tooth 13 is towards the end direction of connecting portion 11, and therefore, when cutting ferrule 3 is retracted, second on cutting ferrule 3 seals tooth
In the first sealing tooth 12 in 13 meeting Snap joint portions 11, it is allowed to fixed.Now, fittings body 1 and cutting ferrule 3 are substituted existing by tooth sealing
There is the face sealing in technology, not only increase sealing property, and connect more stable.
The foregoing is only the utility model preferred embodiment, not thereby limit embodiment of the present utility model and
Protection domain, to those skilled in the art, it should can appreciate that all with the utility model specification and diagram
Hold the scheme obtained by made equivalent substitution and obvious change, should be included in protection model of the present utility model
