Description
Technical field
The utility model is related to a kind of push-lock tubing sealing structures.
Background technology
Gas phase tubing, liquid phase tubing often need to be extended two sections of tubing sealed connections in process of deployment, existing skill
The sealing ring mode sealing effect used in art is unstable, and is easy to fail because of sealing ring aging.
Utility model content
The primary and foremost purpose of the utility model is to provide a kind of push-lock tubing sealing structure, with using in tubing gas phase,
Liquid phase pressure reaches self sealss effect.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of push-lock tubing sealing structure, including tubing, connector, sealing ring and fastening nut；Outside the tubing
Wall is equipped with annular protrusion；The connector is tubular, and both ends are equipped with internal thread；One end of the connector is from the convex annular
The side risen is socketed on the outer pipe wall；The sealing ring is between the connector and the annular protrusion；It is described tight
Gu nut is equipped with external screw thread, and is socketed on the outer pipe wall from the other side of the annular protrusion, and with the connector spiral shell
Line connects.
Preferably, the connector inner wall is equipped with ladder platform, and the ladder platform height is slightly larger than the height of the annular protrusion
Degree, the sealing ring are located in the ladder platform.
Preferably, the annular protrusion by spinning apparatus from the pipe material inner wall mould pressing.
Preferably, the angle of the annular protrusion and the outer pipe wall is more than 90 degree.
Preferably, the annular protrusion is globoidal structure.
Preferably, the side of the annular protrusion sealing ring forms wedge structure.
Push-lock tubing sealing structure provided by the utility model installation is simple, without tool can be realized installation and
Safeguard, and the gas phase in tubing is utilized, liquid phase pressure makes sealing ring deformation, reach self sealss effect.

Embodiment
A kind of push-lock tubing sealing structure, including tubing 1, connector 2, sealing ring 3 and fastening nut 4；The pipe
1 outer wall of material is equipped with annular protrusion 11；The connector 2 is tubular, and both ends are equipped with internal thread；One end of the connector 2 from
The side of the annular protrusion 11 is socketed on 1 outer wall of the tubing；The sealing ring 3 is located at the connector 2 and the annular
Between protrusion 11；The fastening nut 4 is equipped with external screw thread, and is socketed on the tubing 1 from the other side of the annular protrusion 11
Outer wall, and be threadedly coupled with the connector 2.
As the improvement of above-described embodiment scheme, 2 inner wall of the connector is equipped with ladder platform, and the ladder platform height is bigger
In the height of the annular protrusion 11, the sealing ring 3 is located in the ladder platform.
As the improvement of above-described embodiment scheme, the annular protrusion 11 is by spinning apparatus from 1 inner wall spinning of the tubing
Forming, makes 3 deformation of sealing ring using gas phase, the liquid phase pressure in tubing 1, reaches self sealss effect.
As the improvement of above-described embodiment scheme, the annular protrusion 11 and the angle of 1 outer wall of the tubing are more than 90 degree,
Or the annular protrusion 11 is globoidal structure, make sealing ring 3 by when pressure in tubing 1 to connector 2 and annular protrusion 11
Between squeeze, self sealss effect is more preferable.
Similarly, the side of the improvement as above-described embodiment scheme, 11 sealing ring 3 of the annular protrusion forms wedge-shaped knot
Structure makes sealing ring 3 be squeezed between connector 2 and annular protrusion 11 by when pressure in tubing 1, and self sealss effect is more preferable.
1 sealing structure of push-lock tubing provided in this embodiment only needs to form annular protrusion 11 in 1 end precompressed of tubing,
When installation, sealing ring 3 is first sleeved on annular protrusion 11 close to the side of nozzle, and connecting connector 2 is covered from the side, from annular protrusion
The fastening nut being socketed on tubing 1 is connected to connector 2 by 11 other side, you can realizes that one section of tubing 1 is connect with one
The sealed connection of part 2, the sealing element are similar with the connection mounting means of another section of tubing 1.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
