Abstract
The utility model relates to a pipe connector, which comprises a thermoplastic outer pipe and a metal inner core, wherein the inner side of the plastics outer pipe is equipped with a projection, the outer side of the metal inner core is equipped with a cupped portion which is relative to the projection of the outer tube, and the metal inner core is engaged and embedded in the plastics outer pipe through the cupped portion and the projection. The shape of the metal inner core is similar to the shape of the plastics outer pipe, the end portion of the metal inner core is retracted inwardly, thereby forming a cavity which is capable of being inserted and fused by a pipe, a ring fusing step is arranged on the end portion of the metal inner core. Compared with the prior art, the utility model spurns the traditional welded connection and the cutting ferrule connection, the connection of a thin wall metal compound pipe introduces a fusing mode, thereby guaranteeing the reliability of the connection, simultaneously reducing the cost, reducing the difficulty of the installment, improving the heat retaining property of the pipe and the aesthetic property of an interface.
Description
Technical field
The utility model relates to the tubing connection fittings, relates in particular to a kind of tube connection piece that is applied to connect composite pipe.
Background technique
At present, along with continuous progress in science and technology, generally adopt tubing such as pure copper tube, Stainless Steel Tube, Copper-plastic Composite Pipe and stainless steel plastic composite in industry and civil building and other fields, the link kind of these tubing is a lot, but conclude by Placement, mainly contain and be welded to connect three kinds of part, cutting ferrule link, threaded connectors etc., all there is defective separately in these three kinds of links, the used tube material and tube wall of threaded connector is thicker, cost is higher, cutting ferrule link reliability, heat insulating ability are relatively poor, and it is big to be welded to connect the part installation difficulty, and the jointing outward appearance is bad.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of cost low, the tube connection piece of simple, reliability and good heat preservation performance is installed.
The purpose of this utility model can be achieved through the following technical solutions: a kind of tube connection piece, form by thermoplastic outer tube and metal inner core, the inboard of described plastic outer tube is provided with bump, the outside of described metal inner core is provided with and the corresponding depressed part of outer tube bump, described metal inner core is embedded in plastic outer tube by above-mentioned jog cooperation, the shape of this metal inner core is similar to the shape of plastic outer tube, the end ecto-entad indentation of described metal inner core, form one and can supply tubing stretch into the cavity of welding, described metal inner core end is provided with ring-type welding step.
Described thermoplastic outer tube is the polypropylene outer tube.
The brass inner core that described metal inner core is nickel plating or chromium plating.
Described link is a tee pipe fitting.
Described link is a bend pipe tools.
Described link is a pipe joint.
Described link is the screw thread elbow.
Compared with prior art, the utility model has been abandoned traditional being welded to connect with cutting ferrule and has been connected, in the connection of thin-wall metal composite pipe, introduce the welding mode, thereby when guaranteeing connection reliability, reduced cost, lower installation difficulty, improved the heat insulating ability of pipe fitting and the aesthetic property of jointing; The utility model can be widely used in being connected of industry and cool and hot water pipe, purified water for drinking pipe and other fluid-transporting tubing of civil building.
