Abstract
The invention discloses a kind of plumbous automatic control pencil that goes out automatically, not only easy to use owing to the lead for retractable pencil automatically retractable, prevent the lead for retractable pencil fracture, also help the advantage of correcting children's writing posture.The present invention is simple in structure, and parts are few, is easy to assembling, is convenient to promote.
Description
The present invention relates to a kind of writing implement of pencil, particularly can go out plumbous automatic control pencil automatically.
The kind of propelling pencil is a lot of both at home and abroad at present, and conclusion is got up, not outer two big classes.One class be the people for going out lead, wherein bag kind has " upward by formula ", " rotary extrusion type spinning " reach " inferior pumping type " three kinds again, these several pencils go out lead, the processing that all will pause in writing process, use are very inconvenient.One class is to go out lead automatically, as the existing patented technology of West Germany, japanese product and China, and its complex structure, parts are many, and process and assemble is strict, thus price is higher, thus bad for sales.
Purpose of the present invention is to provide a kind of simple in structure, and parts are few, and assembling can go out plumbous automatic control pencil easily automatically.
The present invention can realize that it is made up of button, dynamics adjusting nut, packing ring, dynamics regulating spring, dynamics regulating sleeve, adapter sleeve, lead core tube, penholder, retainer ring, clamping spring, clamper, retaining sleeve, nib and buffering apron by following measure.The flexible of its lead for retractable pencil mainly controlled by the dynamics regulating spring.When the power of writing or suitable with an angle, lead for retractable pencil is subjected to the pressure of dynamics regulating spring, can need stretch out with writing automatically; If write power or improper with an angle, then will compress the dynamics regulating spring, lead for retractable pencil can be withdrawn automatically.
The utility model compared with the prior art, its characteristics are:
1, dynamics governor motion and lead for retractable pencil clamping device establish one's own system respectively, do not disturb mutually;
2, the dynamics adjusting nut be located at outside the penholder regulate simple and convenient;
3, because the lead for retractable pencil automatically retractable is not only easy to use, prevent the lead for retractable pencil fracture, also help the advantage of correcting children's writing posture;
4, simple in structure, be easy to assembling, be convenient to promote.
To in conjunction with the accompanying drawings embodiments of the invention be described in further detail again down;
Fig. 1 is a profile of the present invention
Structure of the present invention such as Fig. 1, it is made up of button 1, dynamics adjusting nut 2, packing ring 3, dynamics regulating spring 4, dynamics regulating sleeve 5, adapter sleeve 6, lead core tube 7, penholder 8, retainer ring 9, clamping spring 10, clamper 11, retaining sleeve 12, nib 13 and buffering apron 14.
Begin to write, press button 1, pressure removes to compress clamping spring 10 by dynamics regulating sleeve 5, adapter sleeve 6, lead core tube 7, retainer ring, because retaining sleeve 12 restriction, cause clamping spring 10 to compress and can not move, therefore force clamper 11 to moving down, so clamper 11 is opened, then lead for retractable pencil can stretch out automatically, and is long as if stretching out, and only need push hard the lead extrusion core slightly makes suitable length.
The dynamics adjusting nut is left-handed, and then the pressure of dynamics regulating spring 4 increases, and causes the contractility of lead for retractable pencil to become big; Otherwise then the pressure of dynamics regulating spring 4 reduces, and causes the contractility of lead for retractable pencil to diminish.
In writing, because the pressure of dynamics regulating spring 4 by adapter sleeve 6, lead core tube 7, retainer ring 9, passes to clamping spring 10, clamper 11 is moved down open, then lead for retractable pencil need be sent with writing automatically.If write power or improper with an angle, then its power of writing is compressed dynamics regulating spring 4 by retaining sleeve 12, clamper 11, retainer ring 9, lead core tube 7, adapter sleeve 6, and then lead for retractable pencil can be withdrawn thereupon.
Buffering apron 14 can be protected the unlikely fracture of lead for retractable pencil in order to vibrationproof.
1 lead for retractable pencil of can packing into of knobbing up.
Claims (4)
1, a kind of propelling pencil of being formed by button 1, dynamics adjusting nut 2, packing ring 3, dynamics regulating spring 4, dynamics regulating sleeve 5, adapter sleeve 6, lead core tube 7, penholder 8, retainer ring 9, clamping spring 10, clamper 11, retaining sleeve 12, nib 13 and buffering apron 14, it is characterized in that dynamics governor motion and lead for retractable pencil clamping device self-organizing system respectively, do not disturb mutually.
2, propelling pencil as claimed in claim 1 is characterized in that dynamics adjusting nut 2 is located at outside the penholder 8, regulates simple and convenient.
3, propelling pencil as claimed in claim 1 is characterized in that buffering apron 14 is housed in nib, prevents the lead for retractable pencil fracture of being shaken.
4, propelling pencil as claimed in claim 1 is characterised in that altogether button 1 can extract, so that pack lead for retractable pencil into.
