Abstract
The utility model discloses a movable joint, which comprises a nut, a threaded joint, a plain joint and a gasket, wherein the outer side wall of the threaded joint is provided with an outer thread, the upper end surface of the threaded joint is provided with an annular slot, the gasket is placed in the annular slot, the plain joint is provided with a vertical pipe extending upwards and an outer edge extending outwards, the plain joint is arranged at the upper end surface of the threaded joint, the outer edge presses the gasket, the nut is provided with a lower edge extending downwards, the inner wall of the lower edge is provided with an inner thread matched with the outer thread of the threaded joint, the vertical pipe abuts upwards the lower edge and is inserted into the nut, and the lower edge is sleeved outside the threaded joint, and is in threaded connection with the threaded joint.
Description
Technical field
The utility model relates to a kind of union connecting for pipe fitting.
Background technique
Tradition pipe fitting Placement varied, have clamp band type connect, be threaded, but these connections all connection part is fixed, it cannot be rotated.
Model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model has been to provide the union that can rotate after a kind of connection.
The utility model takes following technological scheme to complete: union, comprise nut, inipple, plain adapter and packing ring, on the outer side wall of described inipple with outside thread, the upper-end surface of described inipple is with circular groove, described packing ring is inserted in circular groove, described plain adapter has upwardly extending vertical duct and outward extending outer, described plain adapter is placed in the upper-end surface of inipple, described outer packing washer, described nut has the lower edge to downward-extension, the inwall on lower edge is with the internal thread mating with the outside thread of inipple, described vertical duct is upwards pressed close to lower to inserting nut, described lower edge is enclosed within the periphery of inipple, and it is lower to being threaded with inipple.
In the utility model, insert in the upper end of inipple after the plain adapter that needs to connect, only nut screwing clamping can need be completed to connection on inipple, plain adapter after connection coordinates with the packing ring on inipple realizes sealing, plain adapter can also rotate in the space of inipple and nut encirclement formation simultaneously, make the connection sealing between pipe fitting tightr, and can flexible rotating.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The Split type structure schematic diagram of the union that Fig. 1 provides for the utility model the first embodiment, wherein nut is blind nut.
Fig. 2 partly cuts open schematic diagram for the structure of the union that the utility model the second embodiment provides, and wherein nut is round nut.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings more each details and the working principle thereof of embodiment below.
As Fig. 1, shown in Fig. 2, the union that the utility model provides, comprise nut 1, inipple 2, plain adapter 3 and packing ring 4, on the outer side wall of described inipple 2 with outside thread, the upper-end surface of described inipple 2 is with circular groove 5, described packing ring 4 is inserted in circular groove 5, described plain adapter 3 has upwardly extending vertical duct 31 and outward extending outer 32, described plain adapter 3 is placed in the upper-end surface of inipple 2, described outer 32 packing washers 4, described nut 1 has lower to 11 to downward-extension, lower along 11 inwall with the internal thread mating with the outside thread of inipple 2, described vertical duct 31 is upwards pressed close to lower to 11 insertion nuts 1, described lower to 11 peripheries that are enclosed within inipple 2, and be threaded with inipple 2 along 11 under it.In the present embodiment, above-mentioned nut 1 can be with the round nut of through hole upwards, or is the blind nut for upper end closed.
As shown in Figure 1 and Figure 2, in order to make the sealing of packing ring 4 tighter, on described inipple 2 with circular groove 5 cross sections be trapezoidal, described packing ring 4 cross sections are mate with circular groove 5 trapezoidal, described packing ring 4 embeds in circular groove 5, and upwards expose outside circular groove 5 part.
