Abstract
The present invention is a kind of connection fastening type oil drill rocker, including the body of rod, one end of the body of rod is equipped with the first threaded post, the second threaded post, first threaded post, the connection of the second threaded post are integral, first threaded post and second threaded post are coaxial, and first threaded post, the second threaded post, the body of rod are linked together composition multidiameter structure.It has the beneficial effect that：So that connection becomes to consolidate very much, the possibility loosened is very low for such design.
Description
Technical field
The present invention relates to oil drill rockers, and in particular to a kind of connection fastening type oil drill rocker.
Background technology
The connection of existing oil drill rocker is easy to happen loosening, the main reason for loosening be screw thread be squeezed and
Damage.Therefore need to provide a kind of technical solution to solve such technical problem.
Invention content
The present invention provides a kind of connection fastening type oil drill rockers, design and develop screwing for the multigroup screw thread of purpose of the present apparatus
Connection so that connection becomes to consolidate very much, and the possibility loosened is very low.
Present invention employs following technical solutions：A kind of connection fastening type oil drill rocker, including the body of rod 1, the body of rod 1
One end is equipped with the first threaded post 2, the second threaded post 3, and first threaded post 2, the connection of the second threaded post 3 are integral, described
First threaded post 2 and second threaded post 3 are coaxial, and first threaded post 2, the second threaded post 3, the body of rod 1 are linked together structure
At multidiameter structure, the other end of the body of rod 1 is equipped with the first threaded hole 4, the second threaded hole 5, first threaded hole 4, the
Two threaded holes 5 constitute shoulder hole structure, and first threaded hole 4 coordinates with 3 internal and external threads of the second threaded post, and described first
Threaded post 2 coordinates with 5 internal and external threads of the second threaded hole, and 1 head and the tail of the body of rod connect and compose the connection fastening type oil
Drilling rod.
Beneficial effects of the present invention are as follows：First threaded hole 4 coordinates with 3 internal and external threads of the second threaded post, institute
It states the first threaded post 2 with 5 internal and external threads of the second threaded hole to coordinate, forms two groups of screw threads screwed in this way and reach abundant fastening
Purpose, clamping formed depth have hierarchy screw-threaded coupling, the internal and external threads of two groups of different-diameters screw so that fixation more
Add firm.So that connection becomes to consolidate very much, the possibility loosened is very low.
Description of the drawings
Fig. 1 is the schematic diagram that the body of rod 1 of the present invention is connected with each other.
Fig. 2 is the schematic diagram that the body of rod 1 is separated.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1,2：The body of rod 1, the first threaded post 2, the second threaded post 3, the first threaded hole 4, the second threaded hole 5.
One end of a kind of connection fastening type oil drill rocker, including the body of rod 1, the body of rod 1 is equipped with the first threaded post 2, second
Threaded post 3, first threaded post 2, the connection of the second threaded post 3 are integral, first threaded post 2 and second screw thread
Column 3 is coaxial, and first threaded post 2, the second threaded post 3, the body of rod 1 are linked together composition multidiameter structure, the body of rod 1 it is another
One end is equipped with the first threaded hole 4, the second threaded hole 5, and first threaded hole 4, the second threaded hole 5 constitute shoulder hole structure, institute
It states the first threaded hole 4 with 3 internal and external threads of the second threaded post to coordinate, in first threaded post 2 and second threaded hole 5
External screw thread coordinates, and 1 head and the tail of the body of rod connect and compose the connection fastening type oil drill rocker., the first threaded post 2, the second screw thread
The external screw thread of column 3 is all made of the pipe screw thread with taper.
Operation instruction：First threaded hole 4 coordinates with 3 internal and external threads of the second threaded post, first threaded post 2
Coordinate with 5 internal and external threads of the second threaded hole, forms two groups of screw threads screwed in this way and achieve the purpose that fully to fasten, be clamped shape
There is the screw-threaded coupling of hierarchy, the internal and external threads of two groups of different-diameters are screwed at depth so that fixed more firm.
