Abstract
The utility model discloses a kind of plastic-coated steel connectors, it include the plastic layer of tubulose, the plastic layer inner wall is embedded with the metal joint of tubulose, the metal joint both ends are respectively flare, the metal joint inner wall forms cricoid retention bead, the metal joint outer wall forms cricoid reinforcing raised line, and the height of the retention bead is 0.2~0.5mm.The beneficial effects of the utility model are that built-in metal joint makes whole pipeline be metal seamless linking after connection uses, and intensity is more preferable with compressive resistance, long service life more corrosion-resistant than traditional structure, at low cost, easy to install and use.
Description
Technical field:
The utility model relates to plastic-coated steel technical fields, and in particular to a kind of plastic-coated steel connector.
Background technique:
Plastic-coated steel also known as plastics coated tube, steel-plastics composite pipe, plastic coated composite steel pipe, be using steel pipe as matrix, by spray, rolling,
Leaching inhales technique in one layer of plastic anti-corrosion layer of steel pipe (bottom tube) inner surface welding or in the steel modeling of surfaces externally and internally welding plastic erosion resistant coating
Composite steel tube.
Plastic-coated steel generallys use connector in construction and installation and when needing to be attached to realize connection, but straight tube it
Between jointing it is relatively simple, usually pure plastic part, being inserted into connector after being heated by plastic-coated steel outer wall makes it and connects
Together, the intensity of the connector is not high, and compressive resistance is poor, and corrosion resistance is also poor, and service life is short for head hot melt.
Utility model content:
The purpose of this utility model provides a kind of plastic-coated steel connector exactly in order to solve existing issue, built-in gold
Belong to connector makes whole pipeline be metal seamless linking after connection uses, and intensity is more preferable with compressive resistance, more than traditional structure
Add corrosion-resistant, long service life, it is at low cost, it is easy to use.
The technology solution of the utility model is as follows:
A kind of plastic-coated steel connector includes the plastic layer of tubulose, and the metal that the plastic layer inner wall is embedded with tubulose connects
Head, the metal joint both ends are respectively flare, and the metal joint inner wall forms cricoid retention bead, described
Metal joint outer wall forms cricoid reinforcing raised line, and the height of the retention bead is 0.2~0.5mm.
Preferably, the length of the flare of the metal joint end account for metal joint overall length 1/6~
1/5。
Preferably, the metal joint overall length is greater than 10mm.
Preferably, the spacing L between the retention bead end and flare is 2~5mm.
Preferably, the spacing between metal joint inner wall highest point and plastic layer inner wall is greater than 4mm.
The utility model has the beneficial effects that:
The connector of the utility model uses built-in metal joint, make after connection uses whole pipeline be metal without
Seam linking, intensity is more preferable with compressive resistance, long service life more corrosion-resistant than traditional structure, at low cost, and is equipped with limit convex
It rises, when use is easy for installation.
Detailed description of the invention:
Fig. 1 is the utility model structural profile illustration；
Fig. 2 is the structural schematic diagram after the utility model one end grafting plastic-coated steel.
In attached drawing: 1, plastic layer；2, metal joint；3, coating layer；4, metal inner pipe；21, flare；22, it limits
Protrusion；23, raised line is reinforced.
Specific embodiment:
As shown in Figs. 1-2, a kind of plastic-coated steel connector includes the plastic layer 1 of tubulose, 1 inner wall of the plastic layer insertion
There is the metal joint 2 of tubulose, 2 both ends of metal joint are respectively flare 21, and 2 inner wall of metal joint forms
Cricoid retention bead 22,2 outer wall of metal joint form cricoid reinforcing raised line 23, the insertion of reinforcing raised line 23 modeling
In glue-line, it is firmly combined metal joint 2 with plastic layer 1, the height of the retention bead 22 is 0.2~0.5mm, when in use
The metal inner pipe 4 of plastic-coated steel withstands retention bead 22, and when installation is convenient, will not push up excessive.
Specifically, the length of the flare 21 of 2 end of metal joint accounts for the 1/6 of 2 overall length of metal joint
~1/5,21 length of flare is too long to be caused to waste material.
Specifically, 2 overall length of metal joint is greater than 10mm, 2 overall length of metal joint is too short will lead to its with
Easily there is slot in the metal inner pipe 4 of plastic-coated steel when connecting cooperation or cooperation is not close.
Specifically, the spacing L between 22 end of retention bead and flare 21 is 3~5mm, and spacing L is too short
4 intubating length of metal inner pipe is too short when it being caused to connect cooperation with the metal inner pipe of plastic-coated steel, cooperates and easily loosens, not firm enough
Gu spacing L is too long, 4 material of metal inner pipe can be wasted.
Specifically, the spacing between the 2 inner wall highest point of metal joint and 1 inner wall of plastic layer is greater than 4mm, metal joint
Spacing between 1 inner wall of 2 inner wall highest points and plastic layer needs to accommodate the wall thickness and its external coating layer 3 of metal inner pipe 4.
The working principle of the utility model are as follows: plastic-coated steel includes metal inner pipe 4 and the painting that is wrapped in outside metal inner pipe 4
Layer 3 is moulded, the plastic-coated steel connector in this case is for the connection between straight tube, when in use, by the coating layer 3 outside plastic-coated steel
It is heated to softening, be inserted into the connector in this case, the outer diameter of 2 internal diameter of metal joint and metal inner pipe in this case matches
It closes, until metal inner pipe 4 further can not inwardly terminate after withstanding retention bead 22, both ends operation is identical, due to hot melt
Connection, therefore both ends are sealing, so that whole pipeline is metal seamless linking, intensity is more preferable with compressive resistance, compares traditional structure
More corrosion-resistant, long service life is at low cost, easy for installation.
The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness
The range of the utility model protection all should belong in every other embodiment obtained under the premise of labour.
