Description
Technical field：
The present invention relates to plastic-coated steel technical fields, and in particular to a kind of plastic-coated steel connector.
Background technology：
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 spraying, rolling,
Leaching inhales technique in one layer of plastic anti-corrosion layer of steel pipe (bottom tube) inner surface welding or the steel modeling in surfaces externally and internally welding plastic erosion resistant coating
Composite steel tube.
For plastic-coated steel in construction and installation and when needing to be attached, generally use connector realizes connection, but straight tube it
Between jointing it is relatively simple, usually pure plastic article, being inserted into connector after being heated by plastic-coated steel outer wall makes it with connecing
Together, the intensity of the connector is not high, resistance to compression force difference, and corrosion resistance is also poor, and service life is short for head hot melt.
Invention content：
The purpose of the present invention provides a kind of plastic-coated steel connector exactly in order to solve existing issue, and built-in metal connects
For head so that whole pipeline is metal seamless linking after connection uses, intensity is more preferable with compressive resistance, more resistance to than traditional structure
Corrosion, service life is long, at low cost, easy to use.
The technology solution of the present invention 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 limit protrusion, described
Metal joint outer wall forms cricoid reinforcing raised line, and the height of the limit protrusion 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 more than 10mm.
Preferably, the spacing L between the limit protrusion end and flare is 2~5mm.
Preferably, the spacing between the metal joint inner wall peak and plastic layer inner wall is more than 4mm.
The beneficial effects of the present invention are：
The connector of the present invention is using built-in metal joint, so that whole pipeline is metal seamless rank after connection uses
It connects, intensity is more preferable with compressive resistance, more corrosion-resistant than traditional structure, and service life is long, at low cost, and equipped with limit protrusion, makes
Used time is easy for installation.
Description of the drawings：
Fig. 1 is structural profile illustration of the present invention；
Fig. 2 is the structure diagram after grafting plastic-coated steel in one end of the present invention.
In attached drawing：1st, plastic layer；2nd, metal joint；3rd, coating layer；4th, metal inner pipe；21st, flare；22nd, it limits
Protrusion；23rd, 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 limit protrusion 22,2 outer wall of metal joint form cricoid reinforcing raised line 23, the reinforcing raised line 23 insertion modeling
In glue-line, metal joint 2 is made to be firmly combined with plastic layer 1, the height of the limit protrusion 22 is 0.2~0.5mm, when in use
The metal inner pipe 4 of plastic-coated steel withstands limit protrusion 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 long to lead to waste of materials.
Specifically, 2 overall length of metal joint is more than 10mm, 2 overall length of metal joint is too short can cause its with
Easily there is slot during the connection cooperation of metal inner pipe 4 of plastic-coated steel or cooperation is not close.
Specifically, the spacing L between 22 end of limit protrusion and flare 21 is 3~5mm, and spacing L is too short
It is caused to be connect with the metal inner pipe of plastic-coated steel, and 4 intubating length of metal inner pipe when coordinating is too short, and cooperation easily loosens, not firm enough
Gu spacing L is long, 4 material of metal inner pipe can be wasted.
Specifically, the spacing between the 2 inner wall peak of metal joint and 1 inner wall of plastic layer is more than 4mm, metal joint
Spacing between 1 inner wall of 2 inner wall peaks and plastic layer needs to accommodate the wall thickness of metal inner pipe 4 and its external coating layer 3.
The present invention operation principle be：Plastic-coated steel includes metal inner pipe 4 and the coating layer being wrapped in outside metal inner pipe 4
3, when in use, the coating layer 3 outside plastic-coated steel is heated for the connection between straight tube for the plastic-coated steel connector in this case
It to softening, is inserted into the connector in this case, 2 internal diameter of metal joint in this case is matched with the outer diameter of metal inner pipe, directly
Further can not inwardly it terminate after withstanding limit protrusion 22 to metal inner pipe 4, both ends operation is identical, due to hot-melt adhesive paste,
Therefore both ends are sealing so that whole pipeline is metal seamless linking, and intensity is more preferable with compressive resistance, more resistance to than traditional structure
Corrosion, service life is long, at low cost, easy for installation.
The foregoing is merely presently preferred embodiments of the present invention, and those of ordinary skill in the art are not making creative work
Under the premise of all other embodiments obtained, should all belong to the scope of protection of the invention.
