The drilling rod being connected through a screw thread, the torque that can be transmitted is relatively small, and can only transmit unidirectional torque.It is torn open using ring flange connection
Dress is than relatively time-consuming.In the prior art, such as a kind of jumbolter drilling rod fast joint structure of Publication No. CN203961814U, this
Kind of drilling rod fast joint structure is connected and fixed mode using key connection and grafting U-typed card.This connection structure only passes through " U "
Type card fixes two sections of drilling rods, and U-typed Ka Chu is easily accessible boring mud and causes disassembly difficulty in use, and U-typed card may
It can be fallen from card slot, will lead to the separated of drilling rod causes to drill operating interruptions.For another example Publication No. CN205577893U is public
Opened it is a kind of can the auger stem that is threadedly coupled of positive and negative rotation, this auger stem using screw thread and key cooperation connection structure, when
It needs the removable pin that reverse key is covered to outside inwardly to press when needing to dismantle, so that the plunger of removable pin is oppressed elastic slice, release elastic slice
To the barrier effect of fixed pin.The connection structure components of this auger stem are more, structure is complex, manufacture and use not
It is enough convenient.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide, a kind of structure is simple, leakproofness
Interior locking type drilling rod good, convenient for disassembly and assembly and that torsion pass pressure transmission performance is good.
The technical problem to be solved by the present invention is to what is realized by technical solution below.The present invention is a kind of internal lock
Compact form drilling rod, its main feature is that: pin end and female connector including drilling rod ontology both ends, pin end is equipped with torsion pass external splines, female
Connector be equipped with the matched torsion pass internal spline of above-mentioned torsion pass external splines, on the pin end of torsion pass external splines root be equipped with limit
Shoulder, is equipped with installing pipe with one heart in drilling rod ontology, and installing pipe is fixed with close to one end of female connector with externally threaded lock
Tight coupling offers the internal screw thread to match with the external screw thread of lock-on connection on pin end inner wall, and lock-on connection is close to external screw thread
Outer wall be equipped with and compress shoulder, baffle ring is equipped between shoulder and torsion pass internal spline root compressing, in installing pipe close to public access
One end of head is equipped with rotating-barrel mechanism.
A kind of interior locking type drilling rod of invention described above, further preferred technical solution or technical characterstic
Be: the rotating-barrel mechanism includes two rotation slots being symmetrically provided on installation tube wall.
A kind of interior locking type drilling rod of invention described above, further preferred technical solution or technical characterstic
Be: the outer wall of the baffle ring and the inner wall of drilling rod ontology are against setting, and the inner wall of baffle ring and the outer wall of locked joints are against setting.
A kind of interior locking type drilling rod of invention described above, further preferred technical solution or technical characterstic
Be: the length of the installing pipe is no less than the 1/2 of drilling rod ontology total length.
A kind of interior locking type drilling rod of invention described above, further preferred technical solution or technical characterstic
It is: is equipped with rotary seal circle between the installing pipe and drilling rod inner body wall.
Compared with prior art, the invention has the following advantages: pin end and female connector of the invention passes through torsion pass
External splines, the cooperation of torsion pass internal spline are plugged in together, and can preferably be transmitted using torsion pass external splines and torsion pass internal spline positive and negative
Torque；Lock-on connection is connected in pin end by screw threads for fastening, and lock-on connection can be by baffle ring pressure using compression shoulder
Tightly in female connector torsion pass internal spline root, the axial locking of pin end and female connector is realized, being connected through a screw thread can be preferably
Pulling force and lower pressure are transmitted, torque can be transmitted by spline well；The present invention uses two kinds of connection types to pass respectively simultaneously
Torque delivery and pressure, the division of labor is clear, gives full play to the stress advantage of different connection types, simple and reliable for structure, dismounting side
Just.
