Description
Technical field
The utility model relates to a kind of pipe joint, particularly relates to double loose joints elbow.
Technical background
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 90o bend-head combination.Under normal circumstances, welding being carried out in one end of one end of union and 90o elbow makes two pipe fittingss be combined into one.Like this, the other end of union and 90o elbow can carry out welding respectively and two pipelines are connected with orthogonal pipeline, utilize the structure of union, the pipeline connected by this discrete can be rotated.But when 90o elbow and union are combined into one by hot-melt adhesive paste, usually pipe fitting can be caused to scrap because of fusing operation error, waste goods and materials, also connecting to pipeline makes troubles.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and when providing a kind of Pipe installing, two ends can the double loose joints elbow of loose joint.
For achieving the above object, the utility model is by the following technical solutions:
Double loose joints elbow, comprise elbow main body, loose joint is put down and held and internal thread kink, described elbow main body one end is provided with outside thread kink, outside thread kink and elbow main body are formed in one, outside thread kink is slidably located in one end of elbow main body, the end of described elbow main body one end is provided with the first back-up ring, described outside thread kink sagittal plane is against on the first back-up ring, described loose joint is put down the connecting end held with elbow main body one end and is provided with the second back-up ring, described internal thread kink sagittal plane is fastened on the second back-up ring, and its axial internal thread is threaded with outside thread kink; The first described back-up ring is connected with the second back-up ring, is provided with seal ring between the first back-up ring and the second back-up ring.
Described outside thread kink and internal thread kink are by metal material moulding.
Described loose joint is flat hold with elbow main body shaping by plastic materials.
Described outside thread kink threadless one end outer surface is regular hexagon.
Described internal thread kink outer surface is regular hexagon.
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, by outside thread kink and elbow main body one-body molded, make its without the need to again through hot melt operation can by outside thread kink together with elbow body combination, 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; In the cavity that outside thread kink and internal thread kink are formed, seal ring is set between the first described back-up ring and the second back-up ring, thus ensure that the water tightness of joint, reduce the probability that leaking appears in pipeline.The utility model, by outside thread kink and the one-body molded and elbow main body one end that is slidably located in of elbow main body, defines double loose joints elbow, and therefore when connecting, two ends can be rotated, convenient operation, reduces the installation time.In addition, 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.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is further elaborated:
Fig. 1 is the utility model double loose joints elbow cross-section structure simplified schematic diagram;
Fig. 2 is the utility model double loose joints elbow structure simplified schematic diagram.
Embodiment
