Abstract

The utility model discloses a hinged joint with reliability in connection and good sealability. The hinged joint comprises a joint with outer threads at two ends and connecting nuts arranged at two ends of the joint and provided with inner threads, wherein two ends of the joint are provided with connecting cavities which are internally provided with a connecting bearing bush respectively, and each connecting bearing bush is formed by combining two bearing bushes and is symmetrically provided with lug bosses at inner circumference. The hinged joint disclosed by the utility model is suitable for pipeline connection.

Description

The movable joint jointing
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of movable joint jointing that has with the stereoplasm tube linkage function.
Background technique
Along with popularizing of plastic pipes such as PE, PR; Being connected between pipe fitting and the pipe fitting generally adopts joint for plastic tube to connect; And when stereoplasm tubes such as stainless steel are connected with it; Because both thermal expansion coefficient are different, seepage in use can take place or connect unstable phenomenon, influence is normally used.
The model utility content
The technical problem that the utility model will solve provides a kind of movable joint jointing reliable, good airproof performance that connects.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme:
The utility model comprises that two ends have externally threaded joint, are located at the attaching nut that the joint two ends have internal thread; Said joint two ends are provided with connection chamber; Be respectively equipped with the connection bearing shell in the said connection chamber; Said connection bearing shell is combined by two bearing shells, week is arranged with convex in the said connection bearing shell.
As preferably, said connection bearing shell one side is provided with Sealing.
As preferably, said Sealing is made up of the gasket seal of O-ring seals and both sides.
The utility model compared with prior art has following evident characteristic and beneficial effect:
1, connects reliably.Because the utility model has been set up the connection bearing shell in connection chamber, connection bearing shell and connecting tube are fixed, realize that through the attaching nut connecting tube is connected with the good of the utility model again, thereby improved reliability.
2, good airproof performance.Because the utility model adopts combined sealing structure, is made up of an O RunddichtringO and two gasket seals, thereby has effectively improved sealability.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model structural representation in use;
Fig. 3 connects the A-A of bearing shell to amplifying cut-away view among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Like Fig. 1, Fig. 2, shown in Figure 3: the utility model comprises that two ends have externally threaded joint 1; Be located at the attaching nut 2,3 that joint 1 two ends have internal thread, joint 1 two ends are provided with connection chamber, are respectively equipped with in the connection chamber to connect bearing shell 5,6; Connecting bearing shell 5,6 is combined by two bearing shells; Connect bearing shell 5, the 6 interior convexes 7 that are arranged with in week, connect bearing shell 5,6 one sides and be provided with Sealing, Sealing is made up of the gasket seal 9,10 of O-ring seals 8 and both sides; Adopt combined sealing structure, can effectively improve the sealability of the utility model.
As shown in Figure 3: the utility model snaps in the fixed hole on the connecting tube 11 through convex 7 on the connection bearing shell, thereby realizes that connecting tube 11 is connected with the good of the utility model in use.
