Description

Convenient for using the close tubing with connection of Push-fit

Technical field

The invention belongs to tubing technical fields, more particularly to a kind of convenient for using the close tubing with connection of Push-fit.

Background technique

For the tubing in the fields such as municipal drainage, industrial and mineral ventilation, due to being limited by road transport and construction site, usually It is linked into an integrated entity by several tubing socket joints.With the progress of plastic pipe technology, plastic pipe is applied more in above-mentioned field Come more extensive.The sealed connection mode of plastic pipe generally has sealing ring connection, flanged joint or electric melting connection, In at present The pipeline construction scene in the fields such as municipal drainage, industrial and mineral ventilation, plastic pipe in the prior art are tightly connected mode by very Big limitation, such as sealing ring connection type are constructed very laborious, it is easy to damage tubing；Such as flange connection, it needs Biggish construction space；Such as electric melting connection mode, it is desirable that construction site is more dried, in moist or rainy day feelings It cannot construct under condition.

It is a kind of convenient for using the close tubing with connection of Push-fit that application No. is 201710059508.2 disclosure of the invention Female end is set as after one end flaring of tubing, the other end is set as can be with the socket end of female end plug connection, socket joint connection Top of the Shi Mi with ring rib lodges along plugging direction, close on the close inner surface for fitting over expansion mouth in ring rib top surface after socket joint connection Or on the outer surface of plug division, there is no the reset space of reverse strain with ring rib due to close, plug division is difficult to from expansion mouth It is detached from, can also make tubing connection firm without secondary locking mechanism.Socket joint of the above application documents to tubing in the prior art Close to be improved with connection structure, connection installation is quick and convenient, after socket joint tubing it is close match connection effect it is further preferred that, tubing connection jail It leans on, therefore there is simple structure and reasonable design.

The tubing of the inserting mode designed in file disclosed above is after the completion of grafting, in water in the gap of junction Pressure can tend to become larger when increasing, and expansion mouth and plug division junction only have two layers of connection, and intensity is lower, last socket end with hold The synchronous expansion in mouth end, internal solution be extruded under high pressure effect to female end, the close ring rib of matching in socket end junction, after expansion Close with ring rib impact shape to female end, socket end junction, internal high-pressure solution leaks out, the tubing of designed inserting mode Biggish pressure can not be born after the completion of grafting.

Summary of the invention

The purpose of the present invention is to provide a kind of convenient for passing through two of design using the close tubing with connection of Push-fit It is staggeredly mating between the female end and socket end of tubing ontology corresponding end, total public company for thering are five layers to be staggered Socket part improves the anti-pressure ability of junction, improves the reliability of connection, after the completion of solving the connection of existing inserting mode The problem of can not bearing biggish pressure.

In order to solve the above technical problems, the present invention is achieved by the following technical solutions:

The present invention is a kind of convenient for using the close tubing with connection of Push-fit, including tubing ontology, the tubing ontology One end is set as female end after being flared, the tubing ontology other end is set as can be with the socket end of female end plug connection；It is described to hold Mouth end is disposed with the first undertaking notch, the second undertaking notch from inside to outside；The socket end is disposed with from inside to outside First plug division, the second plug division；Described first accepts notch and the first plug division grafting；Described second accepts notch and second Plug division grafting；

The second undertaking notch external annulus is provided with barb outer groove along axial linear arrangement；Second plug division outer ring Face is fixed with close with ring rib with the cooperation of barb outer groove along axial linear arrangement；

The socket end inner wall flaring has third socket；Anchor ring and first is accepted in notch inside the third socket Anchor ring is slidably connected；The female end internal diameter is identical as tubing ontology internal diameter.

Further, first plug division outer end perimeter surface is provided with the second barb outer groove；The first plug division week Side and transition annular groove is provided between the second barb outer groove and end；The second barb outer groove and the second holding groove The second fixed ring rib of mouth outer wall perimeter surface is mating.

Further, section is isosceles trapezoidal structure to the female end in the axial direction；The socket end is in the axial direction Section is isosceles trapezoidal structure；The female end is identical as the inclination angle of the isosceles trapezoidal structure of socket end and range of tilt angles It is 30 ° -60 °.

The invention has the following advantages:

1, staggeredly mating between the female end and socket end of the two root canal material ontology corresponding end that the present invention designs, always The public interconnecting piece for having five layers to be staggered, improves the anti-pressure ability of junction, improves the reliability of connection, interior The liquid in portion is not easy to ooze out from S-shaped gap, barb outer groove therein and it is close with ring rib is mating, outside the second barb Annular groove and the second mating anti-back of ring rib ensure the connection of long-time reliability.

2, female end, socket end is respectively set in the tubing ontology both ends that the present invention designs, and grafting is convenient when in use, connection Securely and reliably.

Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
