Description
Technical field
The utility model is related to sealing ring technical fields, specifically, being related to a kind of pipeline sealing ring.
Background technology
Sealing ring plays important sealing function in two component connection relations, and the gap between two components is made to obtain
Reduce.The pipeline in many equipment is all to add the form of outer tube to obtain the extension of pipeline by inner tube now, now common sealing
Circle is generally conventional circular sealing ring or flat sealed circle, and sealing effect is poor, and required seal request is not achieved.
Utility model content
The purpose of this utility model is to provide a kind of pipeline sealing ring, leakproofness that is easy to use, improving pipeline.
Technical solution is used by pipeline sealing ring disclosed by the utility model:
A kind of pipeline sealing ring, including annular sealing member and the collapsed seal that is extended out from the annular sealing member side
Body, and the collapsed seal body forms the diminishing anti-horn mouth that is open far from annular sealing member, the collapsed seal body is small
Tip inside is the identical concentric circles of radius at mouthful, and the annular sealing member and collapsed seal body are coaxial, the collapsed seal body
Outer wall at least offer the first skewed slot that a notch is smaller, slot bottom is larger, the slot bottom of first skewed slot is close far from annular
Feng Ti, notch are close to annular sealing member.
Preferably, wall at least offers that a notch is smaller, slot bottom is larger in the collapsed seal body second
Skewed slot, the slot bottom of second skewed slot is far from annular sealing member, notch close to annular sealing member.
Preferably, the annular sealing member is equipped with boss in the side being connect with collapsed seal body.
Preferably, the boss medial surface is inclined-plane and boss bottom is small, top is big.
Preferably, the pipeline sealing ring material is rubber.
Preferably, the pipeline sealing ring is integrally formed.
The advantageous effect of pipeline sealing ring disclosed by the utility model is：In pipeline docking operation, by annular sealing member
The cascaded surface of inner tube is withstood, inner tube is close in end at collapsed seal body osculum, and outer tube slowly in access procedure, will slowly be shunk close
Envelope body and annular sealing member are pressed in inner tube, and the anti-horn mouth design of collapsed seal body keeps outer tube slide-in more smoothly while interior
Gap after pipe and outer tube connection between filling inner and outer tubes, leakproofness enhancing, while being opened by the outer wall of collapsed seal body
If notch is smaller, the first skewed slot that slot bottom is larger, the slot bottom of the first skewed slot is far from annular sealing member, notch close to ring packing
Body forms hangnail in the external wall of collapsed seal, and when outer tube skids off, hangnail turns up to form resistance, effectively prevent using because of long-time
It is slided outside outer tube and leakproofness is caused to reduce.
Description of the drawings
Fig. 1 is the stereogram of the utility model pipeline sealing ring；
Fig. 2 is the sectional view of the utility model pipeline sealing ring.
Specific implementation mode
The utility model is further elaborated and is illustrated with reference to specific embodiment and Figure of description:
It please refers to Fig.1 and Fig. 2, a kind of pipeline sealing ring, including annular sealing member 10 and from the annular sealing member 10 1
The collapsed seal body 20 that side extends out, and collapsed seal body 20 is diminishing anti-far from the formation opening of annular sealing member 10
Horn mouth, tip inside 40 is the identical concentric circles of radius at 20 osculum of collapsed seal body, when making outer tube enter to have just enter into, sealing
Circle is close to tip inside 40 at inner tube osculum with inner tube, and annular sealing member 10 and collapsed seal body 20 are coaxial, collapsed seal body
20 outer wall at least offers the first skewed slot 30 that a notch is smaller, slot bottom is larger, and the slot bottom of the first skewed slot 30 is far from annular
Close to annular sealing member 10,20 outer wall of collapsed seal body forms a circle hangnail, hangnail when sliding outside outer tube for seal 10, notch
It turns up to form resistance, effectively prevent causing leakproofness to reduce because long-time outside outer tube using sliding.
20 inner wall of collapsed seal body at least offers the second skewed slot 50 that a notch is smaller, slot bottom is larger, the second skewed slot
For 50 slot bottom far from annular sealing member 10, notch close to annular sealing member 10,20 inner wall of collapsed seal body forms a circle hangnail,
When making sliding outside outer tube, 20 inner ring hangnail of collapsed seal body turns up to form resistance, effectively prevent due to long-time is slided outside using outer tube
Leakproofness is caused to reduce.
Annular sealing member 10 the side being connect with collapsed seal body 20 be equipped with boss 60,60 medial surface of boss be inclined-plane and
60 bottom of boss is small, top is big, and after so that inner and outer tubes is connected, boss 60 wraps outer tube, increases leakproofness.
Pipeline sealing ring material is rubber.
Pipeline sealing ring is integrally formed, and keeps pipeline ring structure more secured.
In said program, in pipeline docking operation, annular sealing member 10 is withstood to the cascaded surface of inner tube, collapsed seal body
Inner tube is close in end at 20 osculums, and outer tube slowly in access procedure, slowly compresses collapsed seal body 20 and annular sealing member 10
Keep outer tube slide-in more smoothly in the anti-horn mouth design of inner tube, collapsed seal body 20, while being filled after inner and outer tubes connection
Gap between inner and outer tubes, leakproofness enhancing, while the smaller, slot bottom by notch that the outer wall of collapsed seal body 20 opens up
The first larger skewed slot 30, the slot bottom of the first skewed slot 30, close to annular sealing member 10, are being received far from annular sealing member 10, notch
20 outer wall of contracting seal forms hangnail, and when outer tube skids off, hangnail turns up to form resistance, effectively prevent using outer tube because of long-time
Outer cunning and cause leakproofness to reduce.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
