Description

Rock core pipe joint hair blank

Technical Field

The utility model relates to a core tube connects technical field, especially relates to a core tube connects blank.

Background

The core barrel is a pipe connected to the drill bit for containing and protecting the core during drilling, and plays a role of guiding the drilling tool during drilling, the common core barrel is only a seamless steel pipe with screw threads at two ends, the diameter of the common core barrel is slightly smaller than that of the drill bit, several core barrels can be connected for preventing the drill hole from being bent, a long and thick drilling tool is formed, and at the moment, joints are needed to connect a plurality of core barrels.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a rock core pipe joint blank aiming at the technical defects, the socket end is adopted to be in a necking shape, and the connection function of the rock core pipe joint is realized through the necking socket end; adopt inside and the socket end of spigot end are provided with many strengthening ribs in body inner wall juncture, effectively promote the bulk strength of rock core coupling through the strengthening rib.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a tube body; one end of the pipe body is provided with a socket end; the other end of the pipe body is provided with a female end; a transition surface is arranged at the junction of the inner part of the socket end and the outer wall of the pipe body at the female end; the socket end is in a necking shape.

Further optimize this technical scheme, be provided with the notch in the position that the body is close to the spigot end.

Further optimising this solution, the recess is arranged inside the socket end.

Further optimize this technical scheme, the socket end is inside to be provided with many strengthening ribs with the female end in body inner wall juncture.

Compared with the prior art, the utility model has the advantages of it is following: the spigot end is in a necking shape, and the connection effect of the core barrel joint is realized through the necking spigot end; 2. adopt inside and the socket end of spigot end are provided with many strengthening ribs in body inner wall juncture, effectively promote the bulk strength of rock core coupling through the strengthening rib.
