The continuous refill for ball-point pen of many steel balls
Technical field
The present invention relates to articles for daily use field, more particularly, to a kind of ball pen.
Background technology
Ball pen mainly uses ball and produces frictional force when writing with paper directly contact, so that ball is rolled in ball seat
Dynamic, take the ink in pen core or ink out of, to reach the purpose write.Ball pen is join that different pigment are write with ink one
Plant pen.Nib is a little steel ball, in bowl made of copper for embedded for a little steel ball small column build, connects afterwards equipped with inkPlastics
Pipe, ink rotates with steel ball and is flowed down by surrounding.Existing ball pen is all only 1 steel ball, and when using, nib is not little sometimes
When the heart scrapes cement flooring or other coarse hard things, steel ball will damage or come off, so whole ball pen just scrap it is impossible to
It is further continued for using.
Content of the invention
The technical problem to be solved is to provide a kind of many steel balls continuous refill for ball-point pen, and this pen core is inside penholder
Preset multiple steel balls, by push rod, standby steel ball can be pressed at nib, substantially increase ball pen in life span
Interior reliability, structure is simple, low cost.
The present invention is realized in:A kind of continuous refill for ball-point pen of many steel balls, including gland, penholder, push rod and steel ball, institute
State the top that gland is arranged on penholder, described steel ball has several, one of steel ball is arranged at the bottom nib of penholder,
Other steel ball is arranged in penholder, and described push rod is arranged in penholder, and the top of push rod and gland are fixedly linked, the bottom of push rod
Portion promotes the steel ball in penholder, is also set with back-moving spring outside the top of push rod.
The bottom of described penholder is provided with guide channel, and at described guide channel bottom nib, the internal diameter of opening is slightly less than
The external diameter of steel ball.
Described guide channel is inverted truncated cone-shaped.
The continuous refill for ball-point pen of the many steel balls of the present invention multiple steel balls in penholder internal preset, steel ball so during using
When accidentally slipping, by push rod, standby steel ball can be pressed at nib, such ball pen remains able to be continuing with, significantly
Improve reliability in life span for the ball pen, structure is simple, low cost.
Brief description
Fig. 1 is the structural representation of the continuous refill for ball-point pen of the many steel balls of the present invention.
In figure:1 gland, 2 penholders, 3 push rods, 4 steel balls, 5 back-moving springs, 6 guide channels.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content of present invention statement, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiment 1
As shown in figure 1, a kind of continuous refill for ball-point pen of many steel balls, including gland 1, penholder 2, push rod 3 and steel ball 4, described pressure
Lid 1 is arranged on the top of penholder 2, and described steel ball 4 has several, and one of steel ball 4 is arranged on the bottom nib of penholder 2
Place, steel ball 4 in addition is arranged in penholder 2, and described push rod 3 is arranged in penholder 2, the top of push rod 3 and gland 1 fixing phase
Even, the bottom of push rod 3 promotes the steel ball 4 in penholder 2, is also set with back-moving spring 5 outside the top of push rod 3.
In the present embodiment, in order to avoid steel ball 4 easily just slips, the bottom of described penholder 2 is provided with guiding and leads to
Road 6, at described guide channel 6 bottom nib, the internal diameter of opening is slightly less than the external diameter of steel ball 4.
In addition, in order to ensure that steel ball 4 is easily pushed in guide channel 6, described guide channel 6 is inverted round platform
Shape, guide channel 6 upper end open is big, and at nib, opening is little, and such steel ball 4 can be relatively easy to enter into guide channel
In 6.
The penholder 2 of the present invention and the penholder of ball pen are integral type, and the continuous refill for ball-point pen of this many steel ball can be directly as
Using, structure is simple, low cost, and reliability is high for piece ball pen.
