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 positive elbow, the liner main body that comprises the rectangular elbow shape of a plastic material, the described liner main body outside is with the overcoat of metal material, described overcoat is connected with the main body injection moulding, the interface position of at least one liner main body has following bayonet arrangement: locking nut is equipped with at the interface position of overcoat, is threaded between overcoat and the locking nut; The joining part site surface of liner main body 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.
Further, on the described liner main body convex shoulder is arranged.
Preferably, the interface position of two liner main bodys has described bayonet arrangement.
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.
