Description
Technical field
The present invention relates to a kind of collar joint flexible sealing structure, belong to collar joint flexible sealing structure product skill
Art field.
Background technology
Current motor vehicle card shell type joint flexible sealing structure is typically by collar joint body, cutting ferrule, nut and pipe
Body constitutes (referring to GB/T3764-2008 cutting ferrules).And the key component cutting ferrule for sealing, metalwork is generally used due to material, and
Machining accuracy is also high, and when being fixedly connected with pipe fitting, forces cutting ferrule end to deform using necking mode and fixed with body；Due to
Being fastened in deformation process can make product sealing surface produce irregular deformation, so as to reduce sealing, easily cause three leakages (leakage
Oil, gas leakage, leak) phenomenon generation.Under serious conditions, motor vehicle steering system or brake system failure will be caused, harm is extremely
It is great.
Sealing qualification rate through the existing sealing structure of market survey is：Qualification rate is 97% when checking pressure is 1.0Mpa；
Qualification rate is 95% when checking pressure is 7.0Mpa；Qualification rate is 92% when checking pressure is 15.0Mpa；Verifying pressure is
Qualification rate is 88% during 30.0Mpa；Qualification rate is 85% when checking pressure is 40.0Mpa.Can be seen with this and have sealing structure
Sealing qualification rate can not meet demand, with pressure rise is used, percent defective rapidly increases.Also, generally using pressure
Under power, qualification rate is also satisfied with without decree manufacturer.
Therefore, existing motor vehicle card shell type joint flexible sealing structure existing defects, are badly in need of being improved.
The content of the invention
Three leakages (oil leak, gas leakage, leak) phenomenon can be effectively prevented to occur it is an object of the invention to provide one kind；It is provided simultaneously with
Difficulty of processing is low, steady quality, the collar joint flexible sealing structure beneficial to mass production.
Basic conception of the invention is：Cutting ferrule sealing surface is revised as a kind of flexible structure, thus reduce Product processing with
And technology difficulty, improve product hermeticity energy.Due to providing a kind of novel collar joint flexible sealing using the present invention
Structure, by hard-hard contact sealing structure of the prior art be changed to firmly-it is soft-contact sealing structure firmly, can effectively prevent three leakages
(oil leak, gas leakage, leak) phenomenon occurs, and can prevent metalwork from deforming；It is provided simultaneously with low difficulty of processing, steady quality, profit
The characteristics of mass production.In actual use, moreover it is possible to by the working of plastics that can be plastically deformed in flexible sealing structure
Or rubber parts plays certain cushioning effect, joint looseness seal failure caused by preventing because being given a shock or impacting, so that
Significantly extend the service life of product.Use collar joint flexible sealing structure sealing effectiveness for：Verifying pressure is
Qualification rate is 100% during 1.0Mpa；Qualification rate is 100% when checking pressure is 7.0Mpa；Checking pressure is qualified when being 15.0Mpa
Rate is 100%；Qualification rate is 100% when checking pressure is 30.0Mpa；Qualification rate is 99.5% when checking pressure is 40.0Mpa.
Can be found out with this be entirely capable of meeting demand using collar joint flexible sealing structure of the present invention, with pressure rise is used, be given up
Product rate has no and substantially increases.And, in the case where pressure is generally used, qualification rate makes manufacturer be satisfied with completely.And then prevented machine
The harm of motor-car steering or brake system failure.
Heretofore described sealing ring (5) be the working of plastics that can be plastically deformed (such as：PA、PE、POM、PET、PBT、
ABS etc.) or rubber parts, its section configuration can be circular or oval or rectangle or abnormal shape.
Heretofore described tubular body (3) and cutting ferrule (4) are linked together by riveting or be welded and fixed, and can also be used
Integral structure is made as an entirety.
Heretofore described nut (2) is rotatable to be slidably mounted on tubular body (3), tubular body (3) and cutting ferrule (4)
It is fixed together (can also use integral structure), one end contacts with nut (2)；Sealing ring (5) is assemblied in tubular body (3)
On cylindrical, one end is contacted with cutting ferrule (4), and the other end is contacted with the conical surface (6) in collar joint body；When nut (2) are rotated,
In the presence of the external screw thread (8) that the internal thread (7) that nut (2) has has with collar joint body (1), promote tubular body (3)
It is mobile to collar joint body (1) with cutting ferrule (4), while force sealing ring (5) to produce plastic deformation, while and collar joint
The internal conical surface (5), tubular body (3) are cylindrical and cutting ferrule (4) is in close contact, and fill mutual gap, form one and are resistant to
The sealing entirety of high pressure, so as to promote sealing function.
Specifically, collar joint flexible sealing structure of the present invention, it is characterized in that at least being connect including bite type
Head body (1), nut (2), tubular body (3), cutting ferrule (4) and sealing ring (5), the collar joint body (1) connect with bite type
The internal conical surface (6) of head and external screw thread (8), the nut (2) is with internal thread (7), tubular body (3) one end outer wall and cutting ferrule
(4) it is fixedly connected, the sealing ring (5) is nested with tubular body (3) one end outer wall and is contacted with cutting ferrule (4), the tubular body (3)
The other end exposed outside through nut (2), the conical surface (6) is adapted in the sealing ring (5) and collar joint body, it is described in
Screw thread (7) and external screw thread (8) are engaged.
Heretofore described tubular body (3) and cutting ferrule (4) can be integral type structure.When the tubular body (3) and cutting ferrule
(4) when for integral type structure, more precisely, cutting ferrule (4) will not also be moved tubular body (3) positioning because of the vibration in use
Position, and then ensure that firmness of the tubular body (3) in whole joint.In other words, tubular body (3) will not in this case
Come off because of external vibration.
Heretofore described sealing ring (5) is PA, PE, POM, PET, PBT or the ABS plastic part that can be plastically deformed etc.
Etc. the sealing ring (5) being made, or the sealing ring (5) being made up of rubber parts, the section configuration of the sealing ring (5) for circular or
Oval or rectangle or abnormal shape, the even special-shaped section with multi-angle.
Compared with the aforementioned existing similar products, collar joint flexible sealing structure of the invention can effectively prevent three leakages
(oil leak, gas leakage, leak) phenomenon occurs；Be provided simultaneously with low difficulty of processing, steady quality, beneficial to mass production the characteristics of.
Present disclosure is further described with the following Examples, but present disclosure is not limited only to implement
Involved content in example.
