Description
Technical field: the automatic propelling device that the present invention relates to a kind of.
Background technology: having had at present can the propelling pencil of automatic propelling, nib can elastic displacement, naturally can press nib, make the automatic propelling device action in pen send core, use easily after the pencil-lead exposed writes.But the structure of this automatic propelling device is quite complicated, the parts needed are many, assembling trouble, and the action chucking power of mechanism acts on pen core surface, easy generation damage, be only applicable to comparatively thin harder pencil-lead, the thicker pen core such as crayon core, erasing rubber core, solid fluorescence core, solid glue core, art designing's charcoal core for soft texture cannot be applied, and promotes the use of and is limited in scope.
Summary of the invention: for the deficiencies in the prior art, the invention provides a kind of simply reasonable in design, is suitable for the automatic propelling device of the pen of various pen core.
The present invention includes the damping pen cap being positioned at a shell front end, this damping pen cap is with back-moving spring, pivoting lever is arranged in a shell and its head exposes the rear end of a shell, one end of pen core is connected with damping pen cap, the other end then connects pen core actuator, the bar portion monodisplacement of this pen core actuator and pivoting lever coordinates, and forms pen core monodisplacement mechanism.
Monodisplacement fit form can have multiple, such as, on pivoting lever, be provided with unidirectional tooth bar, and the top of pen core actuator is provided with elastic fin, and free end and the unidirectional tooth bar of elastic fin match, and forms pen core monodisplacement mechanism.
Or can also be that the top of pen core actuator is provided with taper surface, the friction cap be enclosed within pen core actuator be also provided with taper surface corresponding matching, the bar portion frictional damping of this friction cap and pivoting lever coordinates, and forms pen core monodisplacement mechanism.
Reasonable in design of the present invention is simple, the parts used are few, easy to assembly, displacement mechanism is surperficial without direct chucking power to pen core, damage can not be produced, go for the different crayon core of various thickness soft or hard, erasing rubber core, solid fluorescence core, solid glue core, art designing's charcoal core, pencil-lead etc., have wide range of applications.In use procedure when damping pen cap contact paper, natural displacement can order about internal mechanism and carry out automatic propelling, operation nature is convenient, and pen core is frangibility not, is particularly suitable for children student and uses.
The present invention is further illustrated below in conjunction with drawings and Examples.

Embodiment 1: as shown in Figures 1 to 5, damping pen cap 2 is positioned at a shell 1 front end, this damping pen cap 2 is with back-moving spring 3, pivoting lever 4 is arranged in a shell 1 and its head exposes the rear end of a shell 1, one end of pen core 6 is connected with damping pen cap 2, the other end then connects pen core actuator 5, and the bar portion monodisplacement of this pen core actuator 5 and pivoting lever 4 coordinates, and forms pen core monodisplacement mechanism.The monodisplacement fit form of pen core actuator 5 and pivoting lever 4 can have multiple, the pivoting lever 4 of the present embodiment is provided with unidirectional tooth bar 7, the top of pen core actuator 5 is provided with elastic fin 8, and free end and the unidirectional tooth bar 7 of elastic fin 8 match, and forms pen core monodisplacement mechanism.
In use procedure, after the pen core 6 exposing damping pen cap 2 writes, the front end of damping pen cap 2 touches paper naturally, moves back some distances writing damping pen cap 2 under pressure in shrinking, and now pen core 6 is also withstood by pen core actuator 5 and keeps fixing.When damping pen cap 2 slightly mention leave paper time, back-moving spring 3 is by damping pen cap 2 elastic recovery, now pen core 6 can be pulled outwardly by damping action, pen core actuator 5 is also pulled, lift because the free end of elastic fin 8 moves along unidirectional tooth bar 7, can not block teeth portion, such pen core 6 can be automatically pulled out one section and expose damping pen cap 2 for writing description.Touch paper in the front end writing process of pen core 6 to be also under pressure, but pen core actuator 5 is when pushing inward trend, the free end of elastic fin 8 is pressed down against unidirectional tooth bar 7, and radical length is expanded, firmly block unidirectional tooth bar 7, such pen core actuator 5 cannot move together with pen core 6.
During use, pivoting lever 4 can rotate control unidirectional tooth bar 7 and elastic fin 8 contact cooperation.Be previously used in short-term in pen core 6 length, when namely pen core actuator 5 also moves on to unidirectional tooth bar 7 end, the cooperation departing from unidirectional tooth bar 7 and elastic fin 8 can be rotated, pen core 6 can be taken out completely and change like this.
The top of the pen core actuator 5 of the present embodiment is provided with two elastic fins 8, generally as shown in Figure 4, is staggeredly arranged in opposite directions, certainly also can as shown in Figure 6, and two elastic fins 8 are V-type distribution.Unidirectional tooth bar 7 on pivoting lever 4 also has two, and respectively with two elastic fin 8 corresponding matching, such screens is more reliable.The top of the below of elastic fin 8 free end, pen core actuator 5 also can be provided with smooth filler strip 9, form flaps down supporting construction, elastic fin 8 times compressive strains can be prevented like this, support more firm.In fact, the sidewall of pen core actuator 5 is also provided with pin 10, can prevent from rotating.
As shown in Figure 7, pivoting lever 4 and a shell 1 have displacement gaps in the axial direction, are pressingly to coordinate, also can press pivoting lever 4 so where necessary, move outside pen core actuator 5, and then make pen core 6 also shift out one section, reach the effect of manual knockout.
Embodiment 2: as shown in Fig. 8 to Figure 10, the large portion structure of the present embodiment is substantially identical with embodiment 1, but be provided with taper surface on the top of pen core actuator 5, the friction cap 11 be enclosed within pen core actuator 5 is also provided with taper surface corresponding matching, the bar portion frictional damping of this friction cap 11 and pivoting lever 4 coordinates, and forms pen core monodisplacement mechanism.
Use procedure is also similar, after the pen core 6 exposing damping pen cap 2 writes, the front end of damping pen cap 2 touches paper naturally, some distances are moved back writing damping pen cap 2 under pressure in shrinking, but when damping pen cap 2 slightly mention leave paper time, back-moving spring 3 is by damping pen cap 2 elastic recovery, pen core 6 can be pulled outwardly by damping action, pen core actuator 5 is also pulled outside, because now the taper surface of pen core actuator 5 and the taper surface of friction cap 11 disengage trend, can not be interrupted, such pen core 6 can be automatically pulled out one section and expose damping pen cap 2 for writing description.Touch paper in the front end writing process of pen core 6 to be also under pressure, but pen core actuator 5 is when pushing inward trend, the taper surface of friction cap 11 supports outward by the taper surface of pen core actuator 5, radial dimension expansion trend, the frictional damping of friction cap 11 and pivoting lever 4 increases, and pen core actuator 5 cannot be moved together with pen core 6.
The present embodiment is also provided with shedding deformation groove 12 on friction cap 11, and the radial dimension variation tendency of the cap 11 that rubs like this is more obvious, and the CONTACT WITH FRICTION of pivoting lever 4 is more reliable.Equally, the pivoting lever 4 of the present embodiment and a shell 1 also can be pressingly to coordinate, and also can press pivoting lever 4 so where necessary, reach the effect of manual knockout.
