The technical solution of the utility model: a kind of fitting-type clamping element that connects plastic tube and metallic pipe coupling, it is characterized in that it is made of plastic sheath and metal retaining ring, said plastic sheath outer wall has the hollow slots of stepping down that makes things convenient for the logical part of mounting pipe, and the hollow slots of stepping down is shaped as passes through shape mutually with the logical part of pipe; One end of plastic sheath has radially bounding means, along portion positive stop lug boss is arranged in the opening of other end, and there is restraining groove the positive stop lug boss inboard; Said metal retaining ring outer wall one end has the ring boss, there is ring groove ring boss inboard, plastic sheath and metal retaining ring are when cooperating shape, and then the ring boss of metal retaining ring is butted in the restraining groove of plastic sheath, and the positive stop lug boss of plastic sheath is butted in the ring groove of metal retaining ring.
The logical part of above-mentioned said pipe is the logical part of the above pipe of uniguide link, three-way joint element or threeway.
Above-mentioned said outer wall has the plastic sheath of the hollow slots of stepping down, and the hollow slots of stepping down that its outer wall has can be word distribution, cross distribution, also can triangular in shapely distribute.
The radially bounding means that plastic sheath one end of above-mentioned said trough of belt has is radially rib or radially catch pawl.
Working procedure of the present utility model is: in the pipe connection fittings of earlier preprepared plastic tube is packed into metal retaining ring and plastic sheath composite structure, when plastic tube is in place when promptly being butted on the radially bounding means that plastic sheath one end has, not only can step down to install and make it to cooperate tight but also can conveniently observe and see plastic tube color and the position that assembles by the hollow slots of stepping down on the plastic sheath managing logical part, when plastic tube is in place, its color can be full of whole hollow slots to the bounding means inboard, easy operating the person observe, afterwards, again pipe joint is inserted in the above-mentioned integral plastics pipe, when the insertion end face of plastic sheath withstands on the confined planes of pipe joint, show to be in place.Clamp metal retaining ring with clamping tool this moment, and the position of metal retaining ring is with the screw thread position of malleation at pipe joint, and at this moment, the metal retaining ring of clamped distortion puts plastic tube in place with pipe joint is fastening, and plastic tube and metal pipe docking operation finish at this moment.
The superiority of the utility model product is: 1, the metal retaining ring can be finished fastening butt joint the between plastic tube and the metal pipe smoothly; 2, the plastic sheath usage of band hollow slots is accurate, can determine the working position of plastic tube, the logical part of pipe and metal retaining ring easily, makes the connection of installation uniguide, threeway or the logical part of many siphunculus become convenient, fast, has improved installation efficiency; 3, the total quality of the logical part of connecting tube is improved.
