Description
Technical field:
The utility model belongs to the stationery field, and the active myopia prevention of particularly a kind of favourable SH and sight protectio is write pen.
Background technology:
Existing have various tools, various pencils, ball pen, neutral water-color paintbrush etc. arranged as children and the juvenile writing implement that uses, above-mentioned all tools are except writing function, all can not allow student's eyes keep automatically normalized distance from keep correct body position to write, thereby cause myopia or other vision disorder easily.Trace it to its cause, when the student writes, it is too low to hold a pen, especially preschool child holds in the position of too close nib, blocks normal sight line, inevitable head want askew to a side and on all fours, just can see the writing that nib is write on paper, easily generation kopiopia of a specified duration does not note promptly causing easily hypometropia and stravismus.For this reason, the manufacturer also makes many effort, develop Nearsightedness-preventing pen miscellaneous, as ZL200620010200.6 promptly is the patent of a full-automatic myopia by name, humpback prevention students writing pen, this patent structure includes the cap for brush, penholder, pen cap, nib and nib lid, and the circuit board and the battery of band infrared receiving/transmission probe dynamically is installed in the penholder; Be pivoted with a thrust pin and in the pen cap and be convexly set in the power switch of pen cap outer surface, this power switch is extracted back automatic processing circuit plate power supply at the nib lid, and this thrust pin can be selected to conflict under circuit control or remove the upper end of conflict at pen core.Its major function is that infrared receiving/transmission mechanism is installed in penholder; and detect from the signal of writer face reflected back by it; whether control pen core upper end is headed on by the thrust pin; if the too close penholder of face; circuit drives thrust pin is removed contacting pen core; in a single day pen core is write pressurized and promptly can be bounced back, and can't use, and reaches protection eyes purpose.This patent provides the supporting of pencil, ball pen and neutral water-color paintbrush pen core, is not suitable for pen, how to design a kind of myopia prevention write pen the utility model research object.
Summary of the invention:
The purpose of this utility model is that the active myopia prevention of a kind of replaceable inking chamber of design is write pen.
Technical solutions of the utility model are achieved in that a kind of active myopia prevention writes pen, include the cap for brush, penholder, pen cap, fountain pen nib and nib lid, the circuit board of being with the infrared receiving/transmission probe and the battery that is fixed on pen arm end dynamically are installed in the penholder; Be pivoted with a thrust pin and in the pen cap and be convexly set in the power switch that pen cap outer surface energy is closed by the nib lid, it is characterized in that being pivoted with between pen cap and fountain pen nib a pen core, pen core is by nib, proposition, proposition overcoat and the ink barrel that is set in proposition overcoat rearward end are formed, dynamically pass the nib and the proposition heel of fountain pen nib and insert solid leading section jointly at the proposition overcoat, proposition overcoat rearward end is inserted solid at the ink barrel leading section, form the ink introduction channel, the ink barrel rear end face can be conflicted by the thrust pin and, between ink barrel rear end and pen cap, be provided with one and remain nib and stretch out back-moving spring outside the fountain pen nib.Whether can the nib of pen core normally be write, conflict on the rear end face of ink barrel according to the thrust pin; Pen core adopts nib, proposition and proposition overcoat and ink barrel split design, and the facility of changing ink barrel is provided, and is perhaps convenient to pouring into ink in the ink barrel.
Have a bigger cydariform inking chamber in the middle part of the described ink barrel, leading section is open interface, and it can form with proposition overcoat rearward end employing close-fitting nested structure and insert admittedly, and the rear end is the pipe bar of diameter less than 5mm, and rear end face of this pipe bar can be conflicted by the thrust pin and be reached.Make full use of the pen cap inner space, make ink barrel under the situation that does not influence dynamic retraction, can many cans ink, prolong the ability of continuing.
Described ink barrel rearward end is arranged with the moveable cap of a band salient point, and the salient point end face of this moveable cap can be conflicted by the thrust pin and be reached, and back-moving spring is set on the moveable cap, and the other end is conflicted on pen cap; Be fixed with a back-up ring in described pen cap, this back-up ring retaining makes the salient point end face keep having with thrust pin front end face the gap of 0.001mm-0.5mm in the lower edge of moveable cap.This gap is not influencing when writing, and eliminates the resistance of thrust pin swing, and the thrust pin can be swung under circuit control flexibly, and action of writing lack of standardization is reacted rapidly.
The utility model is diversified writing pen field; a kind of selection is provided; pen is write has higher practicality and artistry; and by replaceable ink barrel design, use cost is low, changes characteristics simple to operate; it has the myopia prevention function; can impel the writer to keep good pen holding posture all the time, prevent myopia, stravismus with vision protection, reaching initiatively, rectification holds a pen and sitting posture.
