Further, telescopic resilience body structure in a ring.
Further, it is in up-small and down-big tapered squeezing anchor ring that the inside of the dead ring, which is equipped with,;The external thread column Upper end on the outside of be equipped with up-small and down-big taper and be bonded anchor ring;The tapered squeezing anchor ring fitting of the dead ring is extruded in outer spiral shell On the taper fitting anchor ring of line column.
Further, the dead ring is made of polytetrafluoroethylene material.
The beneficial effects of the utility model
The utility model is additionally arranged guide post, is respectively equipped with a guide groove in the lower end surface two sides of dead ring, then will Dead ring is inserted in the upper end of guide post by guide groove, and what such dead ring can be more stable is mounted in annular mounting groove; The utility model is equipped with annular mounting groove, the lower end inside of annular mounting groove and upper spiral shell on the outside of the abutting land of upper nipple The inside of line connector communicates, and telescopic resilience body is mounted on the inner upper end of annular mounting groove by the utility model, and dead ring is pacified Mounted in the interior lower end of annular mounting groove, the internal screw thread of upper nipple is rotatably mounted on by external thread column in lower nipple When in anchor ring, telescopic resilience body is pressed down against dead ring and makes to be fitted on the inside of dead ring on the outside of the upper end of external thread column, by In a longitudinal lateral section for the dead ring of the utility model be in " shape structure, using dead ring to the upper end of external thread column and four Zhou Jinhang squeeze fitting so that external thread column of the invention connect with internal screw thread anchor ring more consolidate.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model.
Fig. 2 is the fractionation schematic cross-sectional view of the utility model.
Specific embodiment
The content of the present invention is described in further detail with reference to the accompanying drawing.
As illustrated in fig. 1 and 2, a kind of guide type ocean threaded drillpipe, including upper nipple 2, lower nipple 1, fastening Ring 3, telescopic resilience body 4, guide post 5;2 lower end inside of upper nipple is equipped with internal screw thread anchor ring 22;The interior spiral shell The upper end of line anchor ring 22, which is equipped with, abuts land 23;Annular mounting groove 21 is equipped on the outside of the abutting land 23;The annular The inside of the lower end inside of mounting groove 21 and upper nipple 2 communicates;The telescopic resilience body 4 is mounted on annular mounting groove 21 Inner upper end;The dead ring 3 is mounted on the interior lower end of annular mounting groove 21;The downward bullet of telescopic resilience body 4 Push dynamic dead ring 3;The upper end of the lower nipple 1 is equipped with external thread column 11;The lower nipple 1 passes through outer spiral shell Line column 11 is rotatably mounted in the internal screw thread anchor ring 22 of nipple 2;The external thread column 11 of the lower nipple 1 it is upper End face, which is connected to, abuts 23 lower end surface of land;A longitudinal lateral section for the dead ring 3 is in " shape structure;The flexible bullet Property body 4 be pressed down against dead ring 3 and be fitted in the inside of dead ring 3 on the outside of the upper end of external thread column 11.The dead ring 3 Lower end surface two sides be respectively equipped with a guide groove 32;The lower section two sides of the annular mounting groove 21 are installed by one guiding respectively Column 5;The dead ring 3 is inserted in the upper end of guide post 5 by guide groove 32.
As illustrated in fig. 1 and 2, further preferably, the telescopic resilience body 4 structure in a ring.Further preferably, described It is in up-small and down-big tapered squeezing anchor ring 31 that the inside of dead ring 3, which is equipped with,;It is equipped on the outside of the upper end of the external thread column 11 upper Small lower big taper is bonded anchor ring 111;The tapered squeezing anchor ring 31 of the dead ring 3 is bonded the cone for being extruded in external thread column 11 Shape is bonded on anchor ring 111.Further, the dead ring 3 is made of polytetrafluoroethylene material.
The utility model is additionally arranged guide post 5, is respectively equipped with a guide groove 32 in the lower end surface two sides of dead ring 3, so Dead ring 3 is inserted in the upper end of guide post 5 by guide groove 32 afterwards, what such dead ring 3 can be more stable is mounted on annular In mounting groove 21;The utility model is equipped with annular mounting groove 21, annular mounting groove on the outside of the abutting land 23 of upper nipple 2 The inside of 21 lower end inside and upper nipple 2 communicates, and telescopic resilience body 4 is mounted on annular mounting groove 21 by the utility model Inner upper end, dead ring 3 is mounted on to the interior lower end of annular mounting groove 21, lower nipple 1 pass through external thread column 11 When being rotatably mounted in the internal screw thread anchor ring 22 of nipple 2, telescopic resilience body 4 is pressed down against dead ring 3 and makes dead ring 3 Inside be fitted on the outside of the upper end of external thread column 11, since a longitudinal lateral section for the dead ring 3 of the utility model is in " shape knot Structure carries out extruding fitting to the upper end of external thread column 11 and surrounding using dead ring 3, so that external thread column of the invention 11 and internal screw thread anchor ring 22 connect it is more firm.
