Abstract
The utility model discloses vibration pen core, relate to field of stationery, be specifically related to a kind of transformation of pen core structure.Comprise pen core (1) and writing core nib (2), writing core nib (2) is installed on the lower end of pen core (1), and the inside of pen core (1) bottom is provided with flexure strip (3), and the shape of flexure strip (3) is V-shaped; The fixed edge (4) of the V-shaped of flexure strip (3) is fixed on the inwall of pen core (1), and the upper surface of the active edges (5) of the V-shaped of flexure strip (3) is provided with groove; Active edges (5) cross section of flexure strip (3) is circular, and its diameter is less than the diameter of pen core (1).The utility model solves the pen core existed in prior art accurately cannot judge the problem whether ink uses.
Description
Technical field
The utility model relates to field of stationery, is specifically related to a kind of transformation of pen core structure.
Background technology
Water fillable, the accessory of writing implement, can repeatedly replace.With the tube of ink or ink among the ball shaft of a writing brush, there is metal penpoint front end, nib is embedded with the ball write, and common Neutral ball-point for ball-point pen nib diameter is different.It has irreplaceable effect in study and office, but we also have some inconvenience when using it.Such as do not know that when pen core ink is soon with having done, can not spare lead refills in time, cause the generation of a lot of problem, even can lead to miss significant opportunity.Although producer also makes transparent on design pen core and the pen cap now, so that user observes the service condition of ink, on market, the pen cap is mostly nontransparent, does not also observe the service condition of pen core.Thus spare lead refills is still important thing in life and work in time.
Pen core of the prior art also exists and accurately cannot judge the shortcoming whether ink uses.
Utility model content
The utility model provides vibration pen core, solves the pen core existed in prior art and accurately cannot judge the problem whether ink uses.
For solving the problem, the utility model adopts following technical scheme: vibration pen core, and comprise pen core 1 and writing core nib 2, writing core nib 2 is installed on the lower end of pen core 1, and the inside of pen core 1 bottom is provided with flexure strip 3, and the shape of flexure strip 3 is V-shaped; The fixed edge 4 of the V-shaped of flexure strip 3 is fixed on the inwall of pen core 1, and the upper surface of the active edges 5 of the V-shaped of flexure strip 3 is provided with groove; Active edges 5 cross section of flexure strip 3 is circular, and its diameter is less than the diameter of pen core 1.
Advantage of the present utility model: the utility model adds flexure strip in pen core, when ink makes to use up, the active edges 5 of flexure strip can collide with fixed edge 4, pen core is caused to shake, and through conduction and the reducing of tube wall, oscillation intensity increases, can obviously vibrate at nib place, even the pen cap also can vibrate, and user now can be reminded to change pen core.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is I place partial enlarged drawing in Fig. 1.
Symbol description in figure: 1 be pen core, 2 be writing core nib, 3 be flexure strip, 4 be fixed edge, 5 be active edges, 6 for the pen cap.
Detailed description of the invention
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1-2, vibration pen core, comprise pen core 1 and writing core nib 2, writing core nib 2 is installed on the lower end of pen core 1, and the inside of pen core 1 bottom is provided with flexure strip 3, and the shape of flexure strip 3 is V-shaped; The fixed edge 4 of the V-shaped of flexure strip 3 is fixed on the inwall of pen core 1, and the upper surface of the active edges 5 of the V-shaped of flexure strip 3 is provided with groove; The active edges cross section of flexure strip 3 is circular, and its diameter is less than the diameter of pen core 1.
The fixed edge 4 of flexure strip 3 is 1.8-2.2 centimetre with the distance of writing core nib 2 lower end.
The active edges of flexure strip of the present invention is separated with stator due to the damping action of ink in pen core, when ink makes to use up, active edges collides due to elastic reaction and fixed edge, pen core is caused to shake, and through conduction and the reducing of tube wall, oscillation intensity increases, can obviously vibrate at nib place, even the pen cap also can vibrate, and user now can be reminded to change pen core.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
Claims (2)
1. vibrate pen core, comprise pen core (1) and writing core nib (2), writing core nib (2) is installed on the lower end of pen core (1), it is characterized in that, the inside of pen core (1) bottom is provided with flexure strip (3), and the shape of flexure strip (3) is V-shaped; The fixed edge (4) of the V-shaped of flexure strip (3) is fixed on the inwall of pen core (1), and the upper surface of the active edges (5) of the V-shaped of flexure strip (3) is provided with groove; Active edges (5) cross section of flexure strip (3) is circular, and its diameter is less than the diameter of pen core (1).
2. vibrate pen core as claimed in claim 1, it is characterized in that, the fixed edge (4) of flexure strip (3) and the distance of writing core nib (2) lower end are 1.8-2.2 centimetre.
