Type wheel and ink writer
Technical field
The present invention relates to ink writer technical field, particularly relate to a kind of type wheel and ink writer.
Background technology
At present, after tubing manufactures molding, generally require on tubing, mark its model, size, manufacturer's letter
Breath or any one or more information such as material, to realize the functions such as differentiation between tubing.In tubing information
Tubing ink writer is often used to realize on mark.
As it is shown in figure 1, the structural representation that it is a kind of existing tubing ink writer.As it can be seen, this print
Word machine includes support 110, is arranged at the type wheel 120 on described support 110, and is arranged at described lettering
Guide wheel 130 below wheel.Wherein guide wheel 130 is used for supporting tubing, and type wheel 120 or guide wheel 130 permissible
Relative to the other side up and down, move left and right so that tubing is fixed by type wheel 120 or guide wheel 130 and
Information needed is stamped on it.
And during ink writer uses for a long time, the ink on type wheel surface can penetrate into type wheel wheel body with
Between lettering wheel shaft in the gap of contact, referring to Fig. 2, the wheel body 210 of type wheel is arranged on wheel shaft 220
B point in face is easy to be stained with ink, process over time, after ink parches solidification, and the wheel body of type wheel
210 will be sticked together with wheel shaft 220, make type wheel wheel body be difficult to from wheel shaft and unload, and then cause
Dismounting difficulty when dismounting and change or cleaning type wheel, and it is easily damaged type wheel.
Summary of the invention
In view of this, the present invention provides a kind of type wheel and ink writer, for solving the ink contamination of type wheel
The wheel body causing type wheel is difficult to technical problems such as dismantling and be easily damaged.
The present invention provides a kind of type wheel, comprising: wheel body, wheel shaft, top cap;Wherein, described wheel body,
It is sheathed on described wheel shaft;Top cap, is sheathed on described wheel shaft, and abuts with described wheel body.
Further, described top cap engages socket by thread with described wheel shaft.
The present invention also provides for a kind of ink writer, its type wheel as above.
In sum, type wheel provided by the present invention and ink writer, when dismantling the wheel body of type wheel, only
Top cap need to be rotated to dismantle wheel body, it is to avoid the impact of ink type wheel, decrease in unloading process print
The damage of character wheel.
Accompanying drawing explanation
Fig. 1 show the structural representation of a kind of existing tubing ink writer;
Fig. 2 show the schematic cross-section of a kind of existing type wheel;
Fig. 3 show the schematic cross-section of a kind of type wheel that one embodiment of the invention is provided;
Fig. 4 show one embodiment of the invention and also provides for a kind of ink writer.
Detailed description of the invention
For making the purpose of the present invention, feature become apparent, below in conjunction with the accompanying drawings the present invention is embodied as
Mode is further described.
In view of the type wheel of prior art tubing lettering during long-time use, the ink on type wheel
The contact surface between wheel body and wheel shaft can be polluted, solid along with ink, and then make wheel body the most firm with wheel shaft
Adhere and connect together, cause when dismantling type wheel, cause wheel body dismounting difficulty, and be easily damaged type wheel.
Attachment structure between wheel body and the wheel shaft of the type wheel of the improvement that the present invention proposes, thus avoid lettering oil
The ink impact on type wheel, decreases the type wheel damage at unloading process.
Refer to Fig. 3, the structural representation of its a kind of type wheel provided by one embodiment of the invention.Such as figure
Shown in, this type wheel, including: wheel body 310, wheel shaft 320, top cap 330;Wherein, described wheel body 310,
It is sheathed on described wheel shaft 320;Top cap 330, is sheathed on described wheel shaft 320, and with described wheel body 310
Abut;Described top cap 330 is sleeve-shaped, and its inwall has thread, and by described thread and described wheel shaft
Engagement socket.Utilize above-mentioned type wheel during long-time use, ink contamination wheel body 310 and sheathed with
The contact surface between top cap 330 on wheel shaft 320 and solid make wheel body 310 and top cap 330 stick in one
Rise, when dismantling type wheel wheel body, it is only necessary to rotate top cap 330, by the thread of described top cap 330 inwall
And engage the described wheel shaft 320 of socket with thread, top cap 330 will be produced one axial along described wheel shaft 320
Power, make wheel body 310 depart from described wheel shaft 320 smoothly, thus broken away from the ink harm to type wheel,
Decrease the damage in type wheel unloading process.
In embodiments of the present invention, described top cap 330 engages socket by thread with described wheel shaft 320, from
And make top cap 330 in rotation process, and rely on intermeshing thread between wheel shaft 320, can be to top
Cap 330 produces an axial propulsive force, and then promotes wheel body 310 to depart from wheel shaft 320 smoothly.
Refer to Fig. 4, the embodiment of the present invention also provides for a kind of ink writer, including support 410, is arranged at described
Type wheel 420 on support 410, and it is arranged at the guide wheel 430 below described type wheel.Wherein type wheel
420 are used for lettering body, have any one the type wheel structure described in above example.
In sum, type wheel that the embodiment of the present invention is provided and ink writer, at the wheel body of dismounting type wheel
Time, only need to rotate top cap to dismantle wheel body, it is to avoid the ink impact on type wheel, decrease unloading process
In damage to type wheel.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention, Ren Hesuo
Belong to and technical field has usually intellectual, without departing from the spirit and scope of the present invention, various when making
Change and retouching, therefore protection scope of the present invention is when being as the criterion depending on those as defined in claim.
