Abstract
The utility model discloses a copper and plastic composite connector. The copper and plastic composite connector comprises a copper connector body and a plastic tube. The copper connector body is connected with the plastic tube. The copper connector body is connected with a hexagon nut in a threaded mode. A seal ring is tightly buckled by the hexagon nut and connected with the plastic tube. An arc groove is formed in the periphery of the connection portion between the copper connector body and the plastic tube. According to the copper and plastic composite connector, the copper connector body is connected with the hexagon nut in the threaded mode, the seal ring is tightly buckled by the hexagon nut and connected with the plastic tube, the arc groove is formed in the periphery of the connection portion between the copper connector body and the plastic tube, and therefore the technical problem that an ordinary connector is prone to water leakage, looseness and the like is solved.
Description
Technical field
The utility model relates to a kind of pipe connector lug, and a kind of copper is moulded composite-joint specifically.
Background technique
Joint is widely used in pipeline, each kind valve body connection function at present.Its structure of traditional joint is mostly the moulding of metal integrally casting, mainly exist be easily corroded, get rusty, the technological deficiency such as joint easily leaks.Certainly at present also exist some composite-joints and be mainly used in the connection of plastic pipe, there are the technological merits such as anticorrosive property is strong, easy to connect, but composite-joint is owing to being that the material of two kinds of materials connects, along with the variation of serviceability temperature tends to occur the leak of liquid fault of becoming flexible, coming off and cause in joint.How to prevent that the soundness of leaking and connecting from appearring in composite-joint, be the object that those skilled in the art study the working life of improving composite-joint always.
Summary of the invention
The utility model provides a kind of simple in structure, stable connection, copper easy to use to mould composite-joint.
A kind of copper is moulded composite-joint, comprise copper sleeve and plastic pipe, copper sleeve and plastic pipe join, the described copper sleeve hexagon nut that has been threaded, hexagon nut, by the seal ring connection plastic pipe that links closely, is close to the plastic pipe of connecting part to prevent because gap, the loosening water leakage fault causing appear in connecting part by seal ring; Described copper sleeve and plastic pipe connecting part periphery are provided with arc groove, make copper sleeve and plastic pipe join more stable firmly, the phenomenon such as prevent slip, come off.
On described copper sleeve outer tube wall and inner tubal wall, be equipped with screw thread, make joint more convenient in the time using connection, two kinds of Placements are provided.
The inwall caliber of described plastic pipe and one end, copper sleeve connecting part is less than the inwall caliber of the other end, to increase the fluid flow by plastic pipe.
Described plastic pipe and copper sleeve connecting part periphery are provided with two above tread plates, and tread plate distributes around plastic pipe even circumferential; Described tread plate and plastic pipe integrated injection molding, guarantee that copper moulds composite-joint and under use state, be difficult for skidding etc. technological deficiency, for user provides the stronger power that screws.
Described plastic pipe is provided with protruding positioning strip away from one end periphery of copper sleeve, the screw thread of positioning strip and copper sleeve periphery plays tooth position on same axis, and it completes pipeline after screwing and the conformity of composite-joint link position can to guarantee the pipeline that connects by the utility model.
The utility model is by the copper sleeve hexagon nut that has been threaded, hexagon nut links closely seal ring to connect the arc groove that plastic pipe and copper sleeve and plastic pipe connecting part periphery are provided with, and has solved ordinary couplings and the technical failure such as has easily leaked, becomes flexible in connecting part.
Brief description of the drawings
Be illustrated in figure 1 the utility model copper and mould composite-joint sectional structure schematic diagram.
Embodiment
Copper is moulded a composite-joint as shown in Figure 1, comprises copper sleeve 1 and plastic pipe 4, and copper sleeve 1 joins with plastic pipe 4, copper sleeve 1 hexagon nut 2 that has been threaded, and hexagon nut 2 links closely seal ring 6 to connect plastic pipe 4; Copper sleeve 1 is provided with arc groove 7 with plastic pipe 4 connecting part peripheries.On copper sleeve 1 outer tube wall and inner tubal wall, be equipped with screw thread.
Be less than the inwall caliber of the other end as the preferred plastic pipe 4 of structure and the inwall caliber of copper sleeve 1 one end, connecting part.
Mould the power that screws of composite-joint in order to improve copper, plastic pipe 4 and copper sleeve 1 connecting part periphery are provided with two above tread plates 3, and tread plate 3 distributes around plastic pipe 4 even circumferentials; Tread plate 3 and plastic pipe 4 integrated injection moldings.
