About using advanced optimizing for dynamics:
Magnet if it does not exist then supports the conflict power generated between fixed link and support guide slope, and dynamics optimum range is as follows:
Normal writing physical strength+anti-error dynamics≤conflict power generated between support fixed link and support guide slope+support inner cylinder Interior reset spring falls to elastic force≤pen core maximum receiving dynamics-allowable error dynamics < pen core that interior bar generates is adjusted from desk It falls, the impact force that pen tip generates with making;
Magnet if it exists, and support fixed link be one when, then dynamics optimum range is as follows:
Normal writing physical strength+anti-error dynamics≤is fixed by the conflict power+support generated between support fixed link and support guide slope The reset spring in magnetic attraction+support inner cylinder between bar and adjusting interior bar is held to elastic force≤pen core maximum that interior bar generates is adjusted It is fallen by dynamics-allowable error dynamics < pen core from desk, the impact force that pen tip generates with making;
Magnet if it exists, and support fixed link be two and its it is above when, then dynamics optimum range is as follows:
Normal writing physical strength+anti-error dynamics≤is fixed by the conflict power+support generated between support fixed link and support guide slope The reset spring in magnetic attraction+support inner cylinder on bar between magnet is withstood forces to elastic force≤pen core maximum that interior bar generates is adjusted Degree-allowable error dynamics < pen core is fallen from desk, the impact force that pen tip generates with making;
Interpretation about above-mentioned normal writing physical strength: personalized designs can be carried out for different crowd, with the reality of different crowd Border situation formulates normal writing physical strength;A total normal writing physical strength can also be formulated for all groups, it is ensured that owner can be with It is normal to write;
Interpretation about above-mentioned anti-error dynamics: during actual production, the quality and actual effect of product can exist certain Amplitude, so, it is thus necessary to determine that dynamics offsets this influence;
The interpretation of dynamics is born about pen core maximum: when pen core produces, just determining it, there are a damage dynamics, but this is damaged The threshold of dynamics is close much higher than normal writing physical strength, and with the dynamics of shatter-resistant;But still it cannot achieve complete shatter-resistant; But its threshold meets design concept of the invention, is enough;
Interpretation about allowable error dynamics: if we are using pen core maximum receiving dynamics as standard, pen core service failure Probability will increase, so, need to reduce the range of this practical threshold, allowable error dynamics is then in preferably protection pen core It determines;
And it is laborsaving in order to easily facilitate people, then the smaller the better using dynamics, then practical dynamics is closer to normal writing+anti-error Dynamics, using effect is better, meanwhile, it is also maximum to the protection of pen core.
Stress analysis, is divided into the following four stage:
1, stand the stage: in the case where External force interference, the pen tip of pen core keeps the state for exposing penholder;
2, assault phase: when pen core is by the impact force for being greater than normal writing physical strength, then the meeting of support guide slope and fixed slope are divided From at this point, support fixed link, which can then enter, stablizes release area;Then quickly through stablize discharge area so that the pen tip of pen core into Enter in penholder, but also really its impact main body of impact force, by the pen tip of pen core, then is penholder;And the pen tip of pen core is only It bears at the beginning, the part of impact force of maximum threshold is also born without departing from it;And really it is enough to destroy pen core nib structure Impact force, then born by penholder;
3, the pressure release stage: the shock of a fall power at the beginning, after breaking the balance for supporting fixed link and adjusting land rapidly, repercussions It will continue to compressing reset spring, and the reset spring being therefore further compressed absorbs the kinetic energy of this part of impact force, then Accumulation of energy will be completed, after waiting impact forces to fail, is rebounded, this is harmful for pen core, because, the ring after falling Border is changeable, and the pen tip of the pen core to quick rebound may collide other objects, to cause secondary injury to pen tip; And it is shaken caused by impacting, can also have certain impact to the ink in pen core itself, can if things go on like this adversely affect;Therefore This, it should the impact force that this part repercussions of venting generate;After supporting fixed link to leave stable release area, damping will be entered Slope, and damp its outer diameter of slope be it is incremental, there is certain slope, so, damping slope can pass through frictional force and support fixed link Deformability carrys out this remaining repercussions impact force of offset;To reduce impact and compression to reset spring;
4, reseting stage: when repercussions impact force is damped slope, support fixed link and reset spring counteracting totally, then bullet is resetted Spring can discharge its compressed elastic force, enter again from standing chamber using chamber to push and adjust interior bar;And damp at this time slope and Fixed link is supported, generated frictional force can then weaken the elastic force that reset spring is discharged;Until support fixed link enters stabilization Discharge area, and at this time the elastic force of reset spring also discharge it is similar, still, damping slope and support fixed link, it is generated Frictional force also disappears, and stablizing release area then will not generate excessive frictional force with support fixed link;So fixed link to be supported Again it completes to contradict with adjusting land, that is, completes to reset.
The analysis of pen tip rate travel:
It 1, should be quick withdraw in penholder when receiving impact;
2, pressure release at a slow speed is carried out in penholder, until a moment of pausing is stood, after the completion of impact force absorbs;
3, pen tip starts to spring back at a slow speed, but at this point, pen tip does not expose penholder yet;
4, pen tip just exposes penholder, restores at a slow speed, returns to use state.
Structure of the invention is concentrated mainly on tail portion, so, it also may be incorporated into other existing lamps structure;Have it anti- Fall and correct the effect of writing physical strength;Such as, increase a pen cover for the present invention, thus, when not in use, pen cover is covered, in use, Pen cover is taken away, when falling or is firmly overweight, internal adjusting land and support fixed link can be just triggered, so that its pen core be made to withdraw In penholder;Or it is incorporated in the pen tool of other modes of operation, the function of making it have shatter-resistant and prevent writing physical strength overweight.
Compared with prior art, it after using above-mentioned technical proposal, has the following beneficial effects:
One, technically simple, production cost is low, can be widely applied;
Two, has the function of shatter-resistant;
Three, easy to use, mode of operation is quick;
Four, stable structure after using and distinguishing without using mode of operation, can prevent from accidentally grasping;
Five, the dynamics of rectifiable writing, the crowd that correction section habit is firmly write;
Six, it can be used as the attached shatter-resistant structure of other structures;
Seven, it can restore automatically, after falling, picking up can continue to write.
