Description
Technical field
The invention belongs to tubing technical field, be specifically related to it is a kind of convenient for using the close tubing with connection of Push-fit,
It is mainly used in the fields such as municipal drainage pipe, industrial and mineral ventilation duct.
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 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.
" a kind of throttle type socket joint connects tubing without pad " (patent No.: 201310250854.0, the applying date:
2013.06.21), the novel bell and spigot frame for describing a kind of plastic pipe is fitted close so that tubing is close with company using annular ring
It connects, the tubing being connect using spacing collar with annular groove cooperation secondary locking phase socket joint.Tubing is to the close-fitting essence of annular ring
Spend it is more demanding, slightly mistake or annular ring interference fit, tubing socket joint is very laborious, is easy to damage in work progress
Tubing, construction efficiency is low, and construction cost is higher；Annular ring clearance fit, tubing cannot be close with connection, it is difficult to reach and apply
The design requirement of work.In socket joint connection procedure, with the increase for being fitted close annular ring, construct more and more laborious, and spacing collar
Secondary locking design with annular groove cooperation undoubtedly again increases difficulty of construction, even in the endpiece of socket joint connection procedure
Spacing collar fails to set into annular groove, loses the purpose of design of secondary locking.
Summary of the invention
The present invention mainly solves technical problem present in the above-mentioned prior art, provides a kind of convenient for using socket joint side
The close tubing with connection of formula.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: one kind is convenient for using socket joint
The close tubing with connection of mode, is set as female end after one end flaring of the tubing, the other end is set as to insert with female end
The socket end connect in succession is equipped with limit baffle ring close to socket end on outer pipe wall, and female end is limited in slotting when plug connection
On the limit baffle ring at mouth end, the female end and socket end are one of following two kinds of structure types: structure one, the female end
Expansion mouth inner surface is smooth, and axially spaced-apart setting is several close with ring rib, Mi Peihuan rib on the plug division outer surface of the socket end
Section it is wedge shaped, Mi Peihuan rib is tilted along plugging direction, and the inclination alpha of Mi Peihuan rib medial surface is 60-75 degree, and close matches ring
The outer diameter D on rib top is slightly larger than the internal diameter d of expansion mouth, and the inner port of expansion mouth, which squeezes close ring rib of matching, when socket joint connects makes its top
It lodges along plugging direction, after socket joint connection on the close inner surface for fitting over expansion mouth in the close top with ring rib；Structure two, it is described to hold
Axially spaced-apart setting is several close with ring rib on the expansion mouth inner surface at mouth end, and the section of Mi Peihuan rib is wedge shaped, and Mi Peihuan rib is suitable
Plugging direction inclination, the inclination alpha of Mi Peihuan rib medial surface be 60-75 degree, the plug division smooth outer surface of the socket end, and
The close internal diameter d ' with ring rib top is slightly smaller than the outer diameter D ' of plug division, and the external port of plug division squeezes close with ring rib when socket joint connects
Its top is set to lodge along plugging direction, after socket joint connection on the close outer surface for fitting over plug division in the close top with ring rib；Also,
In the structure one and structure two, the top of Mi Peihuan rib is by the close outside with ring rib towards the close medial surface cambered surface mistake with ring rib
It crosses.
Preferably, the inner surface of expansion mouth is equipped with and the close barb consistent with ring rib spacing in the structure one
Inner groove, barb inner groove away from pipe end be arranged, socket joint connection after the close top with ring rib it is close with embedded in it is corresponding
On hook inner groove；In the structure two, the outer surface of plug division be equipped with the close barb outer groove consistent with ring rib spacing,
Barb outer groove is arranged away from pipe end, and the close top surface with ring rib is close with embedded in corresponding barb outer groove after socket joint connection
On.
When adjacent tubing socket joint connects, deformation occurs the top of Mi Peihuan rib lodges along plugging direction, Mi Peihuan rib
Top surface is slided on the inner surface of expansion mouth or on the outer surface of plug division, and the rear close top surface with ring rib close can match socket joint in place
On the inner surface of expansion mouth or on the outer surface of plug division, there is no the reset space of reverse strain, grafting with ring rib due to close
Portion is difficult to be detached from from expansion mouth, can also make tubing connection firm without secondary locking mechanism.
It outside by the close top design Cheng Youmi with ring rib with ring rib, can towards the close medial surface cambered surface transition with ring rib
To further decrease resistance when socket joint connection, conducive to accelerating construction progress, construction efficiency is improved.
It is equipped on the inner surface of expansion mouth and deviates from the close barb inner groove consistent with ring rib spacing, barb inner groove
Pipe end setting, the close top surface with ring rib is close with being embedded on corresponding barb inner groove when socket joint；Or outside plug division
Surface is equipped with close with the consistent barb outer groove of ring rib spacing, and barb outer groove is away from pipe end setting, when socket joint
The close top surface with ring rib is close on corresponding barb outer groove, and two kinds of structure types all play the work of secondary locking
With so that tubing connection is more firm.
The present invention is close to the socket joint of tubing in the prior art to be improved with connection structure, and connection installation is quick and convenient,
After socket joint tubing it is close match connection effect it is further preferred that, tubing connection is firm, therefore has the characteristics that simple structure and reasonable design.
