Abstract

The utility model relates to a movable joint of a pipeline, belonging to the field of connecting pieces of pipelines and comprising a joint A, a joint B and a locking nut. The locking nut is movably sleeved on the joint B through a bulge on the joint B; the joint A is sleeved with the joint B through a conical surface; the locking nut is connected with the joint A through a thread; and internal threads are respectively processed at the outer ends of the joint A and the joint B. The two joints of the movable joint of the pipeline are sleeved with each other through the conical surface and are locked and fixed through the locking nut, thereby the utility model solves the problems that a loose joint pad is needed to be additionally arranged between prior movable joints of a pipeline, and the loose joint pad is easily damaged by screwing when being installed and screwed to cause the movable joint to leak water. In addition, the utility model has the advantages of simple structure, convenient installation and use and good sealing effect, and is suitable for the connection of various pipelines.

Description

The Pipe moveable joint head
Technical field:
The utility model relates to a kind of Pipe moveable joint head, metal conduit link field.
Background technique:
In the connection of pipeline, generally all be to adopt union to connect, the loose joint that existing pipeline connects is to adopt the car seam, the mounting type that adds the loose joint pad, but easily the loose joint pad is revolved wound during the rotation of this mounting type, cause the union of pipeline to leak, and need reinstall, not only time-consuming but also take a lot of work.
Summary of the invention:
The purpose of this utility model is: a kind of loose joint pad that need not to install additional is provided, by the conical surface cooperation of two connecting heads, conical surface is closely contacted and reached pipe coupling by locking nut again to seal; And have simple in structure, easy to install, the Pipe moveable joint head of good sealing effect.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of Pipe moveable joint head, it is made up of connecting head A, connecting head B and locking nut, it is characterized in that: on connecting head B, connecting head A is by conical surface and connecting head B socket by the protruding movable set on the connecting head B for locking nut, and locking nut and connecting head A are by being threaded.
The outer end of described connecting head A and connecting head B is shaped on internal thread respectively.
The utility model beneficial effect compared with prior art is: two connecting heads adopt the conical surface socket, and be locked by locking nut, solved between the existing Pipe moveable joint head and will install the loose joint pad additional, when being installed, rotation easily the loose joint pad is revolved wound, the problem that causes union to leak, and simple in structure, easy to install, good sealing effect.
Description of drawings:
Accompanying drawing is the structural representation of Pipe moveable joint head.
Among the figure: 1, connecting head A, 2, locking nut, 3, connecting head B, 4, internal thread, 5, projection, 6, conical surface, 7, screw thread.
Embodiment:
This Pipe moveable joint head is made up of connecting head A1, connecting head B3 and locking nut 2, and locking nut 2 movable sets and can not be deviate from by 5 barriers of the projection on the connecting head B3 on connecting head B3.Connecting head A1 is connected with connecting head A1 by screw thread 7 by the locking nut on the connecting head B3 2 after the socket by conical surface 6 and connecting head B3 socket again, makes conical surface 6 sockets of connecting head A1 and connecting head B3 firm, and reaches the pipe coupling sealing.The outer end of connecting head A1 and connecting head B3 is shaped on internal thread 4 respectively, and its effect is to be used for connecting with the outside thread of the pipe head that will be connected.
During use, earlier connecting head B3 is connected with the pipe head that will be connected by internal thread 4, again connecting head A1 is connected with another root pipe head that will be connected by internal thread 4, again connecting head A1 is connected by conical surface 6 with connecting head B3 after connecting, at last locking nut 2 is connected by screw thread 7 with connecting head A1 and tightens, then connecting head A1 and connecting head B3 cooperating by conical surface 6, the Pipe moveable joint head is sealed fully, and do not need to add again in addition the loose joint pad, and it is simple in structure, easy to install.
