Abstract

The utility model relates to a pipe connector, which comprises a connecting pipe member which is used for connecting pipes. The internal wall of one end of the connecting pipe member is provided with internal threads, and the corresponding end part of the outer wall of a pipe is provided with external threads. The end part of the pipe is embedded in another pipe, and the external wall of the other pipe is provided with an annular groove. An annular clamping spring is arranged in the annular groove. An annular sealing ring and a baffle ring are orderly sheathed on the outer wall of the other pipe. The internal diameter of the other end of the connecting pipe member shrinks inward and is sheathed on other pipe. The internal side of an end opening of the connecting pipe member is contacted with the annular clamping spring. The other end of the connecting pipe member is matched and connected together with the pipe by the internal threads and the external threads. The utility model has the advantages of simple structure, convenient installation, superior sealing performance and long service life.

Description

Assembling pipe joint
The utility model relates to a kind of assembling pipe joint, relates in particular to a kind of assembling pipe joint that is used for conveyance fluid.
Traditional assembling pipe joint mainly comprises: the connection pipe fitting that is used for connecting tube, be positioned on the inwall at connection pipe fitting two ends and be respectively arranged with internal thread, be provided with outside thread with the corresponding pipe end outer wall of connection pipe fitting, be fastenedly connected by outside thread and internal thread respectively between pipeline and the connection pipe fitting, realize interconnecting between the pipeline, this connection pipe fitting adopts prefabricated standard piece to make mostly; Simultaneously, in order to improve the connection sealability between the pipeline, also between connection pipe fitting and pipeline, be provided with Sealing usually.But, because in the installation process of pipeline, the row of pipeline establishes general fibrous root and decides according to the concrete condition of erecting bed, the length of pipeline often can not pre-determine, therefore, the screw thread of pipe end needs after its length is determined, could carry out scene processing by the workmen.For this reason, there are many shortcomings in the assembling pipe joint of this structure when installing and using: because the outside thread process equipment of this pipeline is comparatively simple, the main manpower processing and fabricating that relies on forms, therefore, the externally threaded quality of processing of pipeline is difficult to guarantee, might influence the quality of connection of pipeline enclosure, and working strength of workers is higher, the installation speed of pipeline is slower; In addition, the externally threaded process equipment of these pipelines is relatively heavier mostly, carries also comparatively inconvenience.
It is a kind of easy for installation that the purpose of this utility model is to provide, and connects reliably, do not need the assembling pipe joint of field fabrication screw thread on pipeline outer wall.
For realizing the purpose of this utility model, a kind of assembling pipe joint comprises: the connection pipe fitting that is used for connecting tube, the inwall of connection pipe fitting one end is provided with internal thread, corresponding with it pipe end outer wall is provided with outside thread, the internal diameter of described pipe end and the corresponding cooperation of the external diameter of another pipe end, the end of pipeline is embedded in another pipeline, this pipeline outer wall is provided with annular groove, one notched annular spring is arranged in the annular groove, be arranged with O-ring seal and baffle ring on the outer wall of pipeline successively, the port of O-ring seal and pipeline offsets, baffle ring is arranged between annular spring and the O-ring seal, the internal diameter of another pipe end of connection pipe fitting is set on the pipeline after inwardly shrinking, the internal diameter of its serrated end matches with the external diameter of pipeline, the inner side surface and the annular spring of its serrated end offset, and are fastenedly connected by internal thread and outside thread between connection pipe fitting and the pipeline.
The utility model has the advantages that: this apparatus structure is simple, and is easy for installation; Because Sealing is arranged on the outside of pipeline, therefore, also can guarantee the sealability and the operational safety of this device, increases the service life.
Describe in detail bright below in conjunction with accompanying drawing furtherly to the utility model:
Fig. 1 is the exploded perspective view of the utility model assembling pipe joint;
Fig. 2 is the sectional view of the utility model assembling pipe joint.
1, pipeline, 2, pipeline, 3, connection pipe fitting, 4, internal thread, 5, outside thread, 6, annular groove, 7, annular spring, 8, O-ring seal, 9, baffle ring.
As Fig. 1, shown in 2, a kind of assembling pipe joint comprises: be arranged on the connection pipe fitting 3 between pipeline 1 and the pipeline 2, the inwall of connection pipe fitting 3 one ends is provided with internal thread 4, the outer wall of corresponding with it pipeline 1 end is provided with outside thread 5, the corresponding cooperation of external diameter of the internal diameter of pipeline 1 end and another pipeline 2 ends, the end of pipeline 2 is embedded in another pipeline 1, pipeline 2 outer walls are provided with annular groove 6, one notched annular spring 7 is arranged in the annular groove 6, be arranged with O-ring seal 8 and baffle ring 9 on the outer wall of pipeline 2 successively, O-ring seal 8 offsets with the port of pipeline 1, baffle ring 9 is arranged between annular spring 7 and the O-ring seal 8, the internal diameter of connection pipe fitting 3 another pipe ends is set on the pipeline 2 after inwardly shrinking, the internal diameter of its retract port matches with the external diameter of pipeline 2, the inner side surface of its serrated end also offsets with annular spring 7, be fastenedly connected by internal thread 4 and outside thread 5 between connection pipe fitting 3 and the pipeline 1, the cross section of annular spring 7 is circular, inboard at connection pipe fitting 3 serrated ends, for with the corresponding arc shaped surface of annular spring 7 profiles, described O-ring seal 8 can be made by elaxtic seals such as rubber.
In the utility model, because annular spring 7, baffle ring 9 and O-ring seal 8 are set in respectively on the outer wall of pipeline 2, simultaneously, the end of pipeline 2 is embedded in the pipe end of pipeline 1, pipeline 1,2 and connection pipe fitting 3 surround annular spring 7, baffle ring 9 and O-ring seal 8 and separate, therefore, this structure can guarantee that directly not outer with managing interior fluid or the pipe air of seal element contacts, thereby can guarantee the sealability of this device; Simultaneously, owing to when installation, only need offer an annular groove 6 on the outer wall of pipeline 2, can install pipeline, therefore, it installs and uses and processes all very convenient; In addition, because in use, the inboard of connection pipe fitting 3 retract port can produce introversive extruding force to annular spring 7, therefore, annular spring 7 can not produce loosening or displacement on pipeline 2, thereby, can guarantee the firm and unfailing performance that this assembling pipe joint connects, seepage can not take place in long-term the use yet, has prolonged working life.
