Description
Technical field
The utility model relates to a kind of pipe joint, particularly relates to edge copper internal thread Loose joint bend.
Background technique
Union is industry and modal a kind of pipe joint in life, and union makes the connection of pipeline become simpler, dismantles, changes also more easily, greatly save the cost that pipeline connects.When home-use hot water or cold water's pipeline connects, often use the situation of union and the use of edge copper internal thread bend-head combination.Under normal circumstances, thermal fusion welding is carried out in one end of union and plastics one end of edge copper internal thread elbow, two pipe fittingss are combined into one, like this, the internal thread of the metal insert of edge copper internal thread just can be connected with the pipeline external screw joint in pipeline, the other end of union can carry out hot-melt adhesive paste with the plastic pipe in pipeline, utilizes the structure of union, and the pipeline be connected with this discrete can be rotated.But when edge copper internal thread elbow and union hot-melt adhesive paste being combined into one, usually pipe fitting can be caused to scrap because of fusing operation error, waste goods and materials, also connecting to pipeline makes troubles, thus reduces pipe fitting connection construction efficiency.
Summary of the invention
It is convenient, cost-saving that the purpose of this utility model is to provide a kind of Pipe installing, the edge copper internal thread Loose joint bend that connection sealing is good.
For achieving the above object, the utility model is by the following technical solutions:
Edge copper internal thread Loose joint bend, it comprises elbow main body, loose joint is flat holds and internal thread kink, described elbow main body one end is provided with inner screw thread insert, the other end is provided with outside thread kink, described inner screw thread insert and outside thread kink and elbow main body are formed in one, described inner screw thread insert outer side wall is provided with axial flange collar and at least two radial flange collars, described radial flange collar is embedded on the axial inwall in elbow main body one end, described axial flange collar is embedded on the radial junction surface of itself and elbow main body, described elbow main body the other end end is provided with the first back-up ring, one end of corresponding first back-up ring of described outside thread kink is provided with the first baffle ring, the madial wall of described outside thread kink first baffle ring is provided with radial flange collar and axial flange collar, described axial flange collar is embedded on the radial junction surface of itself and the first back-up ring, described radial flange collar is embedded on the axial outer wall of the elbow main body the other end, described loose joint is put down the one end of holding being connected with the elbow main body the other end and is provided with the second back-up ring, the sagittal plane of described internal thread kink is fastened on the second back-up ring, its axial internal thread is threaded with outside thread kink, the first described back-up ring is connected with the second back-up ring, seal ring is provided with between first back-up ring and the second back-up ring.
Described inner screw thread insert, outside thread kink and internal thread kink are by metal material moulding.
Described loose joint is flat hold identical with elbow main material, shaping by plastic materials.
Described inner screw thread insert end face one end is provided with regular polygon column surface, and described regular polygon is square, regular pentagon, regular hexagon, octagon etc., prevents inner screw thread insert from rotating and skids.
The outer surface that described elbow main body is provided with inner screw thread insert one end is provided with equally distributed non-slip bumps.
One end outer surface that described outside thread kink is provided with the first baffle ring is hexagonal structure.
Described internal thread kink outer surface is hexagonal structure.
Described outside thread kink is provided with screw thread one end and extends along first gear ring outer wall direction, and exceeds the first back-up ring.
The utility model adopts above technological scheme, described inner screw thread insert and outside thread kink and elbow main body are formed in one, without the need to edge copper internal thread and union being combined through hot melt operation again, solve the inconvenience of operating process when former technology makes two pipe fittings be combined into one by welding, eliminate the loss because operate miss brings, save operating procedure and installation time, in the cavity that outside thread kink and internal thread kink are formed, seal ring is provided with between the first described back-up ring and the second back-up ring, ensure that the water tightness of joint, reduce the probability that leaking appears in pipeline, described inner screw thread insert end face one end is provided with regular polygon column surface, prevent from inner screw thread insert from rotating to skid.Adopt the utility model Loose joint bend, the pipeline be connected with this discrete can be rotated, eliminate because combined pipe fitting fusing operation is slipped up the loss brought, and, due to without the need to two pipe fittings are carried out welding combination, the length in reserve of former pipe fitting welding end also can be saved, and saves material, reduces manufacture cost.
