The present invention provides a kind of connection-peg, and Fig. 1 to Fig. 3 is an embodiment of connection-peg provided by the invention.
Specifically, Fig. 1 and Fig. 2 are please referred to, in the present embodiment, the connection-peg 100 includes main body 1 and annular seal
Component 2, the main body 1 are cylindrical in shape setting, and one end is formed with the insert port 11 being inserted into for butt joint 200, the annular seal
Component 2 is sheathed in the main body 1, the annular seal component 2 include from the inside to the outside successively the fixed inner seal ring 21 being arranged,
Seat ring 22 and exterior seal ring 23, wherein when the butt joint 200 is inserted into the main body 1, the annular seal component 2 is used
To be sheathed on outside the butt joint 200, the inner seal ring 21 forms sealing to the lateral wall with the butt joint 200 and matches
It closes, the inner sidewall of the exterior seal ring 23 and the main body 1 forms sealing cooperation.
It is described interior close when the butt joint 200 is inserted into the connection-peg 100 in technical solution provided by the invention
Seal 21 and the exterior seal ring 23 are resilient compressive state, when the butt joint 200 and the connection-peg 100 be not conllinear
When, the exterior seal ring 23 can effectively compensate for the distortion not generated collinearly and bias (please referring to Fig. 3).
In the butt joint 200 and the not conllinear connection-peg 100, effectively compensated for by the exterior seal ring 23
The annular seal component 2 still can be kept and 200 vertical seal of butt joint for the distortion and bias not generated collinearly
State, guarantee the effective decrement of the annular seal component 2 and sealed width, reduce the risk of leakage.Specifically, it asks
Referring to Fig.2, in the present embodiment, the trapezoidal setting in section of the exterior seal ring 23, and the thickness of the exterior seal ring 23 exists
In setting is gradually become smaller on the direction of inner sidewall far from the main body 1, in this way in the compensation that ensure that the exterior seal ring 23
It, can also there are the zone of action of the seat ring 22 while the stability of effect.
By the setting of the annular seal component 2, to guarantee the sealing performance of the connection-peg 100, it is possible to understand that
It is that, when the annular seal component 2 is equipped with multiple along the direction of insertion of the butt joint 200, the connection-peg may be implemented
It is multi-sealed between 100 and the butt joint 200, so that whole improve the sealing performance of the connection-peg 100.
When the butt joint 200 insertion (referring to Fig. 1, in the present embodiment, the inner sidewall of the main body 1 is formed with
Cricoid confined planes 13, the confined planes 13 are in be arranged towards the insert port 11, and be in relative to the annular seal component 2
It is arranged far from the insert port 11, to be limited in the direction of insertion of the butt joint 200 to the butt joint 200, passes through
The grafting positioning between the connection-peg 100 and the butt joint 200 may be implemented in the setting of the confined planes 13), it is described interior
Sealing ring 21 and the exterior seal ring 23, in the present embodiment, the material of the inner seal ring 21 and the exterior seal ring 23 is
Silica gel, the sealing ring elasticity better performances of such silica gel material, it is ensured that the inner seal ring 21 and the exterior seal ring 23
Decrement, to guarantee sealing effect.It is understood that the material of the inner seal ring 21 and the exterior seal ring 23 is not
It is limited to silica gel, can be other elaxtic seals similar to silica gel material.
The inner seal ring 21 and the exterior seal ring 23 pass through the seat ring 22 connection (in the present embodiment, the seat
Circle 22 is rigid plastics part or metalwork, and the seat ring 22 is designed as hard member, is compensated in this way in the exterior seal ring 23
When position deviation, it is ensured that the decrement of the inner seal ring 21 is unaffected), specifically, in the present embodiment,
The inner seal ring 21 and the exterior seal ring 23 are adhesively fixed with the seat ring 22, the inner seal ring 21 described in this way and described
Fixed form between both exterior seal rings 23 and the seat ring 22 is relatively simple and secured.
The annular seal component 2 is sheathed in the main body 1, specifically, in the present embodiment, the exterior seal ring 23
It is adhesively fixed with the inner sidewall of the main body 1, is mutually bonded with the main body 1 to fix the ring-type by the exterior seal ring 23
Seal assembly 2, the annular seal component 2 described in this way are installed relatively simple and secured.
Referring to Fig. 2, in the present embodiment, the inner sidewall of the main body 1 is equipped with cricoid mounting groove 12, and the ring-type is close
Sealing assembly 2 is set at the mounting groove 12, and by the setting of the mounting groove 12, the annular seal component 2 may be implemented
Installation positioning.Also, it can be that there are enough spaces for the annular seal component 2 that the mounting groove 12, which is arranged, so that the ring
Shape seal assembly 2 can freely swing, with guarantee the inner seal ring 21 can inclined posture, finally guarantee in not conllinear feelings
The decrement of the inner seal ring 21 can be vertical with the butt joint 200 always under condition.
As described above, the inner sidewall of the exterior seal ring 23 and the main body 1 is adhesively fixed, by the way that the peace is arranged
Tankage 12 can fill more glue in the mounting groove 12 with the fixation exterior seal ring 23 and the main body 1.
Referring to Fig. 4, the seat ring 22 is equipped with notch towards institute in another embodiment of connection-peg provided by the invention
The cricoid interior limiting slot 221 of inner seal ring 21 is stated, the part of the inner seal ring 21 is placed in the interior limiting slot 221
Interior, by the setting of the interior limiting slot 221, the installation that may be implemented between the seat ring 22 and the inner seal ring 21 is fixed
Position.And it is possible to more glue be filled in the interior limiting slot 221, with the fixation seat ring 22 and the inner seal ring
21。
Likewise, the seat ring 22 is equipped with cricoid outer limiting slot 222 of the notch towards the exterior seal ring 23, it is described outer
The corresponding outer limiting slot 222 of sealing ring 23 is convexly equipped with cyclic annular convex ribs 231, and the ring-type convex ribs 231 are placed in the outer limit
In the slot 222 of position, by the cooperation of the cyclic annular convex ribs 231 and the outer limiting slot 222, the seat ring 22 and described may be implemented
Installation positioning between exterior seal ring 23.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the design of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/it is used in it indirectly
He is included in scope of patent protection of the invention relevant technical field.
