Description
Technical field
The utility model belongs to oil extraction technical field, specifically a kind of steady stable connection type oil drill rocker.
Background technique
Drilling rod is to bore mill equipment or bottom outlet device for connecting drilling machine landscape apparatus and being located at drilling well bottom end.The purposes of drilling rod
It is drilling mud to be transported to drill bit, and bottom outlet device is improved, reduced or rotated together with drill bit.In operation drilling rod be according to
Secondary end to end more, currently, the common connection type of drilling rod is threadedly coupled by root.The connection type forms standard, but
In actual use, the link position for still having small probability loosens situation.For this purpose, there are also drilling rods to use thread
Non-return structure between tooth, still, since drilling rod also needs to remove by root, so, non-return structure increases the tired of drilling rod dismounting
Difficulty, or even cause the damage of drilling rod spiral link structure.
Summary of the invention
To solve the above-mentioned problems, the utility model proposes a kind of new drilling rod, the thinking of the utility model is, due to boring
Bar will pressurize in interior bone in operation and inject mud, and the pressure of the mud of pressurization can be used as drilling rod connection knot
The external force of structure.Based on this, the embodiment of the utility model is as follows:
A kind of stable connection type oil drill rocker, including drilling rod ontology；It is equipped in drilling rod ontology coaxial with drilling rod ontology
Mud hole；It is connected with corresponding screw connection structure at the head and the tail both ends of drilling rod ontology, which includes external screw thread
Structure and internal thread structure；Internal thread structure is tubular, and the bottom surface of tubular is provided with first through hole, and first through hole and mud hole connect
Logical, the inner wall of tubular is equipped with internal screw thread, and external thread structure is cylindricality, and the second through-hole, the second through-hole and mud are provided in cylindricality
Hole connection, is equipped with external screw thread, it is characterized in that further including drilling rod disconnecting prevention structure, drilling rod disconnecting prevention structure is outside on cylindrical outer wall
It is provided with radial through-hole on helicitic texture, radial counterbore, the position pair of radial through-hole and radial counterbore are provided on internal thread structure
Answer (in the case where two drilling rods connect appropriate state, the axis of radial through-hole and radial counterbore is overlapped)；
Pin, pressure spring and pin end socket are connected in radial through-hole；Radial through-hole is divided into interconnected inside and outside two sections,
What it is close to the second through-hole is radial through-hole inner segment, and the internal diameter of radial through-hole inner segment is less than the internal diameter of radial through-hole outer segment；The pressure
The outer diameter of spring is identical as the internal diameter of radial through-hole outer segment；The pin end socket spiral is connected to radial through-hole outer segment, pin end socket
Centre be provided with pin hole；The axial cross section of the pin is T-shaped, the outer diameter and radial through-hole outer segment of larger one end of pin
Internal diameter it is identical, the outer diameter of smaller one end of pin is not more than the internal diameter of pin hole；The length of pin is not more than radial through-hole outer segment
Depth；Pressure spring described in smaller one end housing of pin.
The principle of this drilling rod is, in operation, pressure is transmitted to pin, pin ejection, limit by radial through-hole by mud
The radial counterbore in position.When stopping operation, mud loses pressure, then pressure spring resets pin, and radial counterbore is detached from limit state.
Further, the outer surface of the pin end socket is in radial through-hole.It prevents when repairing tooth, pin end socket influences to make
Industry.
Further, the outer surface of the pin end socket is equipped with interior hexagon indent.Convenient for using allen wrench operation.
Further, screw glue is coated between the pin end socket and radial through-hole.Fasten pin end socket and radial through-hole.
The utility model has been bonded adjacent oil drill rocker using new thinking, more reliably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of this oil drill rocker；
Fig. 2 is the partial structural diagram of external thread structure；
In figure: drilling rod ontology 1, mud hole 2, external thread structure 3, internal thread structure 4, first through hole 5, radial counterbore 6, the
Two through-holes 7, radial through-hole 8, pin 9, pressure spring 10, pin end socket 11, pin hole 12.
