Description

The side compression type lettering pen

Technical field

The utility model discloses a kind of side compression type lettering pen, belongs to learning tool class technical field.

Background technology

At present; ball pen can be divided into two big classes substantially; one class belongs to the classification that needs an artificial specially protection pearl; such as; the position that nib is locked in can write by a kind of locking device specific operation by the people when needs use or it is regained in shaft of a writing brush in time spent not perhaps directly just is used as another kind of safeguard measure with the cap for brush.Yet; it is exactly that nib in use is in naked state all the time that all there is a fatal shortcoming in these methods; thereby can not guarantee in use can not make the generation of accidents such as nib and its thing collision; this in addition device also needs artificially to go consciously to protect nib; thereby it is also inevitable owing to as forget that artificial factor such as withdrawal nib causes some to leak and unnecessary consequence such as pollution clothes as pen oil, so also just can not truly protect nib.Have the classification of protecting the pearl function automatically another kind of belonging to, as the patent No. is that the 03241740.3 two automatically pens that protect by the Shen Yihao application are exactly by a kind of device it just to be stretched out nib outside the shaft of a writing brush when being used, and nib is regained in the shaft of a writing brush, thereby reach the effect of protecting point in real time, but because it is not in conjunction with traditional advantage of self-locking fully, but by hand keep in real time the pen the state of writing, to ask for help like this hand in use the maintenance energy that should apply and unstable, do corresponding variation along with the variation of the suffered external force of nib, thereby do not reach the requirement of comfortableness, the most important thing is, when writing for a long time, because the fatigue of hand causes the power inequality that holds a pen, thereby can not satisfy the stability requirement of nib, and then the whole writing effect of influence.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of side compression type lettering pen easy to use, simple to operate.

The utility model is achieved through the following technical solutions:

The utility model comprises the shaft of a writing brush and is installed in pen core in the shaft of a writing brush, and the front end of pen core is with spring, wherein, has the hole on the described shaft of a writing brush and be provided with button in the hole, and this button is connected with interior pipe on being enclosed within pen core by bindiny mechanism.

A side of the close pen core tube wall protrusion of pipe has the projection of two symmetries in described, and locates vertically to have run through a manhole on the lower side at its center, side.

Described bindiny mechanism includes connecting rod, and the two ends of connecting rod respectively are provided with cylinder boss, and wherein in the end cylinder boss connection manhole on inner pipe, the both sides cylinder boss of the other end and the hole of button cooperatively interact by the disc spring of two symmetrical distributions.

The utility model is from the angle of functional characteristic, the pen power that is in what state as long as button is not squeezed (as the people not when writing) no matter, and then nib just can not be exposed to the outside, thereby plays the effect of automatic real-time guard nib.And since this moment button be in high raised position, thereby it in general just as the model of same submarine can allow the people pleasing.When people need write, just can be by the extruding button, make its just with ladder boss engagement till, also be that connecting rod is parallel with interior pipe the time.In this process, since an end of connecting rod with its mutually vertical the body of manhole on the button of hinge down move, thereby drive the motion forward of interior pipe by hinge, and then make nib expose nib, finally reach the state that to write, angle owing to connecting rod in this process and pen core diminishes gradually to zero simultaneously, thereby disc spring will be screwed.Under this state, because big spring is in compressive state, thereby the power that pen core is return together with interior pipe is backward arranged all in real time, because the effect of this power is exactly to make pen real-time recovery be arranged to the trend of not writing state, this point is similar with starting writing certainly in the past.But since its be not by the people again initiatively operation realize its restore funcitons, but make it return to the state do not write by the action (because certain random external factor makes a pen disengaging hand suddenly) of another kind of trigger-type.Thereby from then on angle is said, its different from the past starting writing certainly fully, and similar with above-mentioned said second kind.And, because connecting rod remains vertical with the mobile guide passage of button when writing, so this mechanism is in the dead-centre position, thereby no matter the suffered external force of nib is much, pipe and coupled link motion in all can't promoting, thereby just realized the auto-lock function of traditional pen, satisfied the stability of writing, the requirement of comfortableness.Yet, if lifting button is not under pressure and unclamps hand as the people, then since this moment disc spring also be in the state of screwing, though the size of its moment is very little, be enough to destroy above-mentioned dead point state, like this because the acting in conjunction of the moment of torsion of the thrust of big spring and disc spring, just can overcome the interior friction of system, pipe slides backward in promoting, and then drives by connecting rod and to lift button and move upward, and finally gets back to the state do not write again.

The utilization of the utility model innovation the dead point principle, and by adopting double-slider mechanism as enforcement body.Owing to adopted dead point mechanism; thereby when mechanism is in the dead-centre position; even be subjected to very big external force effect; also can not change the location status of mechanism, but can destroy its dead point state by less moment, thus the whole state of change system; and then realized replacing the function of the state of keeping mechanism more energetically with less power; satisfied the requirement of ergonomics, because compatible advantages such as traditional self-locking, vision protection, real-time guard nib, thereby reach the effect of achieving many things at one stroke.This utility model makes it when not writing state also in its design of having made novelty in appearance, on the whole just as same submarine model, thereby makes it that a kind of appreciation effect also can be provided when not using.
