the utility model aims at providing an outer tooth loose joint structure that the dismantlement between the convenient pipeline, the single spare part of being convenient for to pipeline network are changed and are maintained to what prior art exists exactly.
In order to realize the purpose, the utility model discloses a technical scheme is: outer tooth loose joint structure, including the fixed head, outer tooth loose joint, the intermediate junction cover, the fixed cover of pipeline, the rear end of fixed head peg graft in the intermediate junction cover and with the front end threaded connection of intermediate junction cover, outer tooth loose joint rotationally the cover is established at the middle part of fixed head, the front end outside of outer tooth loose joint is equipped with the external screw thread that is used for connecting other pipelines, the rear end of intermediate junction cover is pegged graft in the fixed cover of pipeline, the middle part of intermediate junction cover and the front end threaded connection of the fixed cover of pipeline, the rear end of the fixed cover of pipeline is connected with pipeline protection spring.
The further improvement of the scheme is that the thread turning directions of the fixed head, the middle connecting sleeve and the pipeline fixing sleeve are the same and are opposite to the thread turning direction of the external thread movable joint.
The further improvement of the scheme is that the screw thread turning directions of the fixed head, the middle connecting sleeve and the pipeline fixing sleeve are right-handed, and the screw thread turning direction of the external thread movable joint is left-handed.
The further improvement of the scheme is that a sealing ring is arranged at the rear end of the threaded connection part of the fixed head and the middle connecting sleeve.
The further improvement of the scheme is that a sealing ring is arranged at the rear end of the threaded connection part of the middle connecting sleeve and the pipeline fixing sleeve.
The further improvement of the scheme is that the outer part of the rear end of the outer tooth loose joint is of a polygon structure.
The pipeline fixing sleeve is further improved in that the outer part of the front end of the pipeline fixing sleeve is of a polygon structure.
The utility model has the advantages that: the utility model provides an outer tooth loose joint structure, including fixed head, outer tooth loose joint, intermediate junction cover, pipeline fixed sleeve, the rear end of fixed head is pegged graft in intermediate junction cover and with the front end threaded connection of intermediate junction cover, outer tooth loose joint rotationally the cover is established at the middle part of fixed head, the front end outside of outer tooth loose joint is equipped with the external screw thread that is used for connecting other pipelines, the rear end of intermediate junction cover is pegged graft in pipeline fixed sleeve, the middle part of intermediate junction cover and the front end threaded connection of pipeline fixed sleeve, the rear end of pipeline fixed sleeve is connected with pipeline protection spring; the outer tooth movable joint of the utility model is rotatably sleeved at the middle part of the fixed head, when the outer tooth movable joint is disassembled, other parts can not rotate due to the rotation of the outer tooth movable joint, thereby being convenient for the disassembly between pipelines and greatly facilitating the replacement and maintenance work of single parts of a pipeline network; the utility model discloses a rear end of the fixed cover of pipeline is connected with the pipeline protection spring, can prevent effectively that the joint end of pipeline from being bent because of the effect of external force to can protect the pipeline effectively.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic sectional view of the present invention.
Description of reference numerals: the device comprises a fixed head 1, an outer tooth movable joint 2, a middle connecting sleeve 3, a pipeline fixing sleeve 4, a pipeline protection spring 5 and a sealing ring 6.
The specific implementation mode is as follows:
the utility model will be further explained with reference to the accompanying drawings, as shown in fig. 1-2, the utility model comprises a fixed head 1, an outer tooth movable joint 2, an intermediate connecting sleeve 3 and a pipeline fixing sleeve 4, the rear end of the fixed head 1 is inserted into the intermediate connecting sleeve 3 and is connected with the front end of the intermediate connecting sleeve 3 by screw thread, the outer tooth movable joint 2 is rotatably sleeved on the middle part of the fixed head 1, the outer part of the rear end of the outer tooth movable joint 2 is in a polygon structure, which is convenient for screwing or unscrewing the outer tooth movable joint 2, the outer part of the front end of the outer tooth movable joint 2 is provided with external screw threads for connecting other pipelines, the rear end of the intermediate connecting sleeve 3 is inserted into the pipeline fixing sleeve 4, the middle part of the intermediate connecting sleeve 3 is connected with the front end of the pipeline fixing sleeve 4 by screw thread, the rear end of the pipeline fixing sleeve 4 is connected with a pipeline protection spring 5, the outer part of, the utility model discloses a but the external tooth loose joint 2 rotationally overlaps the middle part at fixed head 1 and the screw thread direction is different with the screw thread direction of the rest spare parts, when dismantling external tooth loose joint 2, the rest spare parts can not rotate because of the rotation of external tooth loose joint 2, thereby be convenient for dismantle between the pipeline, greatly made things convenient for the work of changing and maintaining the single spare part of pipeline network; the utility model discloses a rear end of the fixed cover of pipeline 4 is connected with pipeline protection spring 5, can prevent effectively that the joint end of pipeline from being bent because of the effect of external force to can protect the pipeline effectively.
