The internal screw thread that screw thread matches；The cleaning piece is set to the inner periphery of cylinder.
Further, the cleaning piece is both ends that are multiple and being distributed in internal screw thread.
Further, the inner wall of the cylinder is additionally provided with poly- dirty slot.
Further, the poly- dirty slot is the strip groove axially extending along cylinder, and gathering dirt slot is multiple and along cylinder circumferential direction
It is uniformly distributed.
Further, the depth of the poly- dirty slot is not less than the height of internal screw thread.
Further, the cleaning piece is annular in shape, and the inner wall of the cylinder is equipped with the annular groove for clamping cleaning piece.
Further, the outer wall of the cylinder is fixed with rod-shaped turning handle.
Further, the cleaning piece is made of sponge.
The beneficial effects of the present invention are: oil tube external thread stay-furring tool of the invention, the external screw thread for being screwed into oil pipe is back-outed i.e. again
Can, convenient for clearing up oil tube external thread, wiping effect can be generated to oil tube external thread by cleaning piece, make snaking processing more
Thoroughly, while cleaning piece can stop dirt to drop down onto ground around, reduce cleaning task afterwards amount, avoid causing dirt to ambient enviroment
Dye, can be improved cleaning efficiency and quality compared with prior art, improves the stability of oil tube connection structure.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the cross-sectional view of Fig. 1；
Fig. 3 is perspective view of the invention.
Specific embodiment
Fig. 1 is the structural diagram of the present invention；Fig. 2 is the cross-sectional view of Fig. 1, and Fig. 3 is perspective view of the invention, as schemed institute
Show: the oil tube external thread stay-furring tool of the present embodiment, including cylinder 1 and cleaning piece 2；The inner wall of the cylinder 1 be equipped with outside oil pipe
The internal screw thread 3 that screw thread matches；The cleaning piece 2 is set to the inner periphery of cylinder 1；The cylinder of internal screw thread 3 and cleaning piece 2 will be had
1 external screw thread for being screwed into oil pipe is back-outed can clear up oil tube external thread again, simple to operate, cleaning piece 2 and external screw thread
Along the axial interphase distribution of cylinder 1, keeps each cleaning piece 2 consistent with oil tube external thread length with externally threaded total length, pass through
Cleaning piece 2 can generate wiping effect to oil tube external thread, effectively remove the dirt remained at the top of external screw thread, make snaking processing more
Thoroughly, while cleaning piece 2 can stop dirt to drop down onto ground around, reduce subsequent cleaning amount, avoid causing ambient enviroment
Pollution, can be improved cleaning efficiency and quality compared with prior art, improves the stability of oil tube connection structure.
In the present embodiment, the cleaning piece 2 is both ends that are multiple and being distributed in internal screw thread 3, can be produced to oil tube external thread
Raw wiping effect, effectively removes the dirt remained at the top of external screw thread, keeps snaking processing more thorough, while cleaning piece 2 can stop
Dirt drops down onto ground around, reduces subsequent cleaning amount, avoids polluting ambient enviroment.
In the present embodiment, the inner wall of the cylinder 1 is additionally provided with poly- dirty slot 4；Dirt can be accommodated, it is easy to use and dirt
Centralized collection processing, gathering dirt slot 4 is the spiral slot that lead angle is greater than internal screw thread 3, can be screwed into cylinder 1 when dirt is more
During dirt is exported, convenient for the removing of dirt.
In the present embodiment, the poly- dirty slot 4 is the strip groove axially extending along cylinder 1, and gathering dirt slot 4 is multiple and along cylinder
Body 1 is circumferential to be uniformly distributed；It is not only easy to process, but also be convenient for the dirt removal in poly- dirty slot 4；Poly- dirt slot 4 is at least three,
Internal thread part is set on cylinder 1 is divided into multiple radially movable sectorial blocks, the outside of cylinder 1 using poly- dirty slot as boundary
(outside of i.e. each sectorial block) it is coaxial be equipped with a sleeve；Sleeve and each sectorial block pass through the dovetail groove along sleeve circumferential direction
It is slidably matched with dovetail slide block, and the radially inner side face part corresponding with each sectorial block of sleeve is spiral cambered surface
(spiral cambered surface is the arcwall face formed along the snail line based on hub internal bore, makes point in spiral cambered surface to sleeve axis
Distance along the circumferentially continuous gradual change of sleeve, the distance of the specially point in spiral cambered surface to sleeve axis is circumferentially clockwise along sleeve
Direction becomes larger), axis axisymmetricly structure of each spiral cambered surface relative to sleeve, sectorial block radial outer side and helical arc
Face matches, therefore each sectorial block can be pushed to move radially inwardly by spiral cambered surface when rotating clockwise sleeve, otherwise band
It moves each sectorial block radially outward to disperse, limiting stand terrace realization sleeve and fan is set by corresponding to dovetail slide block on dovetail groove
The restriction of relative rotation between shape block, and then the amplitude that each sectorial block moves radially is limited, make during being screwed into oil pipe
Screw thread on each sectorial block matches with the screw thread on oil pipe, and realized by the dispersion of each sectorial block during back-outing and
Separation between oil pipe improves snaking efficiency convenient for quickly removing, and since each sectorial block is bascule, cylinder 1 is right
One frame of formation between each sectorial block and sleeve is answered, and forms partition between corresponding adjacent sectorial block, partition diameter is inside
The side wall of end face and adjacent two sectorial block cooperatively forms poly- dirty slot 4.
In the present embodiment, the depth of the poly- dirty slot 4 is not less than the height of internal screw thread 3；The groove bottom of i.e. poly- dirty slot 4 with it is interior
Cylindrical surface corresponding to 3 major diameter of screw thread is equal or lower than cylindrical surface corresponding to 3 major diameter of internal screw thread, effectively can collect and store
Dirt.
In the present embodiment, the cleaning piece 2 is annular in shape, and the inner wall of the cylinder 1 is equipped with the annular for clamping cleaning piece 2
Slot forms Embedded notch, and easy to disassemble, the cross section of the annular groove and cleaning piece 2 is swallowtail-shaped structure, makes
The suit of cleaning piece 2 is more stable in a ring groove, and cleaning piece 2 is avoided to fall off.
In the present embodiment, the outer wall of the cylinder 1 is fixed with rod-shaped turning handle 5, and when use rotates rod-shaped turning handle 5,
Convenient for operation, rod-shaped turning handle 5 is particularly fixed on the outer wall of the sleeve of the outside of cylinder 1.
In the present embodiment, the cleaning piece 2 is made of sponge, not only cheap, but also scale removal performance is good.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
