The continuous refill for ball-point pen of many steel balls
Technical field
The present invention relates to articles for daily use field, relate in particular to a kind of ball pen.
Background technology
Ball pen is mainly to utilize ball directly to contact generation frictional force with paper in the time writing, and ball is rolled in ball seat, takes ink or ink in pen core out of, to reach the object of writing.Ball pen is to join with ink a kind of pen that different pigment is write.Nib is a little steel ball, and little steel ball embedded in made of copper bowl of a small column build, and ink is equipped with in rear connection
plasticspipe, ink rotates and is flowed down by surrounding with steel ball.Existing ball pen is all to only have 1 steel ball, and when nib scrapes cement flooring or other coarse hard things because of carelessness in use sometimes, steel ball will damage or come off, and a whole like this ball pen is just scrapped, and cannot continue to use again.
Summary of the invention
Technical problem to be solved by this invention is to provide the continuous refill for ball-point pen of a kind of many steel balls, this pen core in penholder internal preset multiple steel balls, can steel ball for subsequent use be pressed into nib place by push rod, greatly improved the reliability of ball pen in life span, simple in structure, cost is low.
The present invention is achieved in that the continuous refill for ball-point pen of a kind of many steel balls, comprise gland, penholder, push rod and steel ball, described gland is arranged on the top of penholder, described steel ball has several, and one of them steel ball is arranged on the nib place, bottom of penholder, and other steel ball is arranged in penholder, described push rod is arranged in penholder, top and the gland of push rod are fixedly linked, and the bottom of push rod 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 the internal diameter of described nib place, guide channel bottom 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 in penholder internal preset multiple steel balls, like this when in use procedure when the careless slippage of steel ball, can steel ball for subsequent use be pressed into nib place by push rod, ball pen still can continue to use like this, greatly improve the reliability of ball pen in life span, simple in structure, cost is low.
Accompanying drawing explanation
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.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, the continuous refill for ball-point pen of a kind of many steel balls, comprise gland 1, penholder 2, push rod 3 and steel ball 4, described gland 1 is arranged on the top of penholder 2, and described steel ball 4 has several, one of them steel ball 4 is arranged on the nib place, bottom of penholder 2, other steel ball 4 is arranged in penholder 2, and described push rod 3 is arranged in penholder 2, and the top of push rod 3 and gland 1 are fixedly linked, 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, for fear of steel ball 4 easily with regard to slippage, the bottom of described penholder 2 is provided with guide channel 6, and the internal diameter of described guide channel 6 nib place, bottom openings is slightly less than the external diameter of steel ball 4.
In addition, in order to guarantee that steel ball 4 is easily pushed in guide channel 6, described guide channel 6 is inverted truncated cone-shaped, and guide channel 6 upper end open are large, and little near nib place opening, steel ball 4 can comparatively be easy to enter in guide channel 6 like this.
Penholder 2 of the present invention is integral type with the penholder of ball pen, and the continuous refill for ball-point pen of these many steel balls can directly use as a ball pen, and simple in structure, cost is low, and reliability is high.
