Abstract
A steel-plastic composite straight joint comprises a main body made of plastic, wherein an outer sleeve made of metal and a locking nut are sleeved on the outer side of the main body, the outer sleeve and the main body are connected in an injection molding mode, and the outer sleeve and the locking nut are in threaded connection; the surface of the interface part at the front part of the main body is provided with a sealing ring mounting groove ring and a non-return groove ring with inverted teeth; the front end and the rear end of the C-shaped ring are in an inclined plane shape, the front end of the C-shaped ring is contacted with the inner inclined plane of the locking nut, the rear end of the C-shaped ring is contacted with the front inclined plane of the outer sleeve, and the inner surface of the C-shaped ring is provided with convex teeth which are aligned with the groove ring; the rear part of the main body is provided with a thread for connecting a pipe.
Description
(1) technical field
The utility model relates to a kind of pipe coupling.
(2) technical background
The copper material manufacturing is adopted in existing pipe coupling mostly, and copper sleeve is firm, corrosion-resistant, and it is more satisfactory to be used to make pipe coupling.But because the price of copper skyrockets recently, the price of copper sleeve also rises thereupon.Under this background, joint for plastic tube with low cost arises at the historic moment, but joint for plastic tube is having inborn defective aspect fastness, the serviceability, not sun-resistant and temperature variation, and working life is short, reveals easily, can not large-scale promotion use.
(3) summary of the invention
The utility model will solve low, the easy leakage of intensity of existing joint for plastic tube, the problem of poor durability, provide a kind of existing intensity, durable, anti-leakage good, steel-plastic composite pipe joint with low cost again.
The utility model adopts following technological scheme:
A kind of steel is moulded compound straight joint, comprises the main body of a plastic material, and the described main body outside is with the overcoat and the locking nut of metal material, and described overcoat is connected with the main body injection moulding, is threaded between overcoat and the locking nut; The joining part site surface of body front part has seal ring that groove ring and the non-return groove ring that has pawl are installed; The front and back ends of C shape ring all takes the form of inclined plane, and the front end of C shape ring contacts with the interior inclined-plane of locking nut, and the rear end of C shape ring contacts with the front bevel of overcoat, on the internal surface of C shape ring protruding tooth is arranged, and this protruding tooth is aimed at described groove ring; Back body has and connects the screw thread that pipe is used.
Preferably, described outer putting has the injection moulding through hole, and main body is passed the injection moulding through hole.
Preferably, the inboard of described overcoat has scrobicular ring, and main body is filled up described scrobicular ring.
Main body of the present utility model adopts plastic material, has reduced cost, and plays the overcoat and the locking nut employing metal material of connection and fastening effect, has guaranteed intensity and serviceability.Adopt injection moulding to connect between main body and the overcoat, guaranteed that plastic components is connected with the firm of metal parts.When locking nut screwed, the front and back ends inclined-plane of C shape ring was squeezed, and inwardly shrank, and the protruding tooth on the C shape ring will be pressed into the contact segment of connecting tube over against the groove ring of its below, had played leakproof and the effect that firmly is connected.
The utility model has the advantages that: have good intensity, serviceability and cheap cost concurrently, anti-leakage is good and be connected firmly, being connected firmly of plastic components and metal parts, good airproof performance.
