Further, the cleaning piece is multiple and be distributed in externally threaded both ends.
Further, the outer wall of the axis body is additionally provided with poly- dirty slot.
Further, the poly- dirt slot is along the axially extending bar-shaped trough of axis body, and it is multiple and circumferential along axis body to gather dirt slot
It is uniformly distributed.
Further, the depth of the poly- dirty slot is not less than externally threaded height.
Further, the cleaning piece is annular in shape, and the outer wall of the axis body is equipped with the annular groove for being set with cleaning piece.
Further, the rear end of the axis body is fixed with dish type turning handle.
Further, the cleaning piece is made of sponge.
The beneficial effects of the invention are as follows：The oil pipe internal thread stay-furring tool of the present invention, the internal thread for being screwed into oil pipe are back-outed i.e. again
Can, convenient for clearing up oil pipe internal thread, wiping effect can be generated to oil pipe internal thread by cleaning piece, make snaking processing more
Thoroughly, while cleaning piece can stop that dirt is fallen into oil pipe, reduce cleaning task afterwards amount, avoid causing oil pipe inner space
Pollution, can improve cleaning efficiency and quality, improve the stability of oil tube connection structure compared with prior art.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
Fig. 1 is the structural diagram of the present invention；Fig. 2 is the sectional view of Fig. 1, as shown in the figure：Spiral shell in the oil pipe of the present embodiment
Line stay-furring tool, including axis body 1 and cleaning piece 2；The outer wall of the axis body 1 is equipped with the external screw thread 3 to match with oil pipe internal thread；Institute
The excircle that cleaning piece 2 is set on axis body 1 is stated, the internal thread that the axis body 1 with external screw thread 3 and cleaning piece 2 is screwed into oil pipe is twisted again
Oil pipe internal thread can be cleared up by going out, simple to operate, cleaning piece 2 and external screw thread 3 along the axial interphase distribution of axis body 1,
Make each cleaning piece 2 consistent with oil pipe internal thread length with the total length of external screw thread 3, it can be to spiral shell in oil pipe by cleaning piece 2
Line generates wiping effect, effectively removes the dirt remained at the top of internal thread, makes snaking processing more thorough, while 2 energy of cleaning piece
Blocking dirt is fallen into oil pipe, is reduced cleaning task afterwards amount, is avoided polluting oil pipe inner space, with prior art phase
Than cleaning efficiency and quality can be improved, the stability of oil tube connection structure is improved.
In the present embodiment, the cleaning piece 2 is both ends that are multiple and being distributed in external screw thread 3, and oil pipe internal thread can be produced
Raw wiping effect effectively removes the dirt remained at the top of internal thread, makes snaking processing more thorough, while cleaning piece 2 can stop
Dirt is fallen into oil pipe, is reduced cleaning task afterwards amount, is avoided polluting oil pipe inner space.
In the present embodiment, the outer wall of the axis body 1 is additionally provided with poly- dirty slot 4, can accommodate dirt, easy to use and dirt
Centralized collection processing gathers the spiral slot that dirt slot 4 is more than external screw thread 3 for lead angle, axis body 1 can be screwed into when dirt is more
During dirt is exported, convenient for the removing of dirt.
In the present embodiment, the poly- dirty slot 4 is along the axially extending bar-shaped trough of axis body 1, and it is multiple and along axis to gather dirt slot 4
Body 1 is circumferential to be uniformly distributed, not only easy to process, but also is convenient for the dirt removal in poly- dirty slot 4；Poly- dirt slot 4 is at least three,
Axis body 1 is equipped with externally threaded part and is divided into multiple radially movable secter pats, the center of axis body 1 as boundary using poly- dirty slot
There are one central shafts for (inside of i.e. each secter pat) coaxial setting；Central shaft passes through with each secter pat around central shaft circumferential direction
Dovetail groove and dovetail slide block are slidably matched, and the radial outer side of central shaft and the corresponding part of each secter pat are spiral shell
Revolving cambered surface, (spiral cambered surface is the arcwall face formed along the snail line based on central shaft, makes point in spiral cambered surface to center
The distance of axis axis is along the circumferentially continuous gradual change of central shaft, and the specially point in spiral cambered surface to the distance of center shaft axis is along center
Axis week tapers into clockwise), each spiral cambered surface is relative to the axis axisymmetricly structure of central shaft, and secter pat is radially
Medial surface matches with spiral cambered surface, therefore while rotating clockwise central shaft can push each secter pat by spiral cambered surface radially
It is displaced outwardly, otherwise each secter pat is driven radially-inwardly to draw close, limiting stand is set by corresponding to dovetail slide block on dovetail groove
Terrace realizes the restriction of relative rotation between central shaft and secter pat, and then limits the amplitude that each secter pat moves radially, and makes
Screw thread during being screwed into oil pipe on each secter pat matches with the screw thread on oil pipe, and by each during back-outing
The separation between oil pipe is realized in the gathering of secter pat, convenient for quickly removing, improves snaking efficiency, since each secter pat is lives
Dynamic structure, therefore axis body 1 corresponds to one frame of formation between each secter pat and central shaft, and between corresponding adjacent secter pat
The side wall of formation partition board, partition board radial outer end face and adjacent two secter pat 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 external screw thread 3, i.e., the groove bottom of poly- dirty slot 4 with it is outer
Cylindrical surface corresponding to 3 path of screw thread is equal or cylindrical surface corresponding to less than 3 path of external screw thread, effectively can collect and store
Dirt.
In the present embodiment, the cleaning piece 2 is annular in shape, and the outer wall of the axis body 1 is equipped with the annular for being set with cleaning piece 2
Slot forms Embedded notch, easy to disassemble, and the cross section of the annular groove and cleaning piece 2 is swallowtail-shaped structure, is made
Cleaning piece 2, which is sleeved in annular groove, more to be stablized, and cleaning piece 2 is avoided to come off.
In the present embodiment, the rear end of the axis body 1 is fixed with dish type turning handle 5, and dish type turning handle 5 is consolidated by a center-pole
Due to the center of 1 rear end face of axis body, rotation dish type turning handle 5, easy to operation during use, towards in oil pipe when axis body 1 is screwed into
The front end of one end of side, opposite one end are rear end, and center-pole is particularly fixed on the rear end of the central shaft at 1 center of axis body
Face.
In the present embodiment, the cleaning piece 2 is made of sponge, not only cheap, but also scale removal performance is good.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail in good embodiment, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present 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 right of invention.
