Abstract

The utility model relates to an automatic ink controlling and moisturizing gel-ink pen. A miniature spring for jacking ball is not arranged in a written metal head of a gel-ink pen refill; a cavity in which a spring is mounted is arranged at one end of the gel-ink pen refill; and a ball valve can open and close the cavity end of the gel-ink pen refill under the action of a ball valve ejector rod so as to realize the ink controlling and moisturizing function. By adopting the technical scheme, the production cost of the gel-ink pen is greatly reduced.

Description

Automatically the control China ink neutral pen of jumping of preserving moisture

Technical field

The utility model relates to a kind of writing implement, more specifically says to relate to a kind of automatic control China ink neutral pen of jumping of preserving moisture.

Background technology

What common neutral pen core of jumping pen was stored is ink, because ink is easily mobile, volatile, therefore in the inner mode that adopts ultrafine microsprings roof pressure ball of the nib of pen core, the sealing delivery port prevents that ink from flowing out or volatilization, when writing, the reaction force that provides by paper, the roof pressure ball produces displacement, opens and writes mouth, and ink flows out.There is following defective in said structure: 1, written inner space is minimum, and therefore high for the microsprings requirement of using, at present for the higher microsprings of quality requirement, China also needs import; 2, the price height of spring almost reaches half cost of whole pen core, causes neutral the costing an arm and a leg of pen of jumping, and volume of production and marketing is low; 3, since spring and ball all be and be small, make spring usually can not face the roof pressure ball, form lateral deviation, cause when writing water outlet not smooth; Need apply bigger pressure when 4, writing, be easy to generate and eat the paper phenomenon; 5, under the active force of microsprings, ball comes off easily.

Summary of the invention

The purpose of this utility model is to overcome the defective of existing Neutral ball-point for ball-point pen, and a kind of no microsprings pen core that uses is provided, and has the black performance of keeping humidity of good control, cheap and good-quality neutral jump.

For achieving the above object, the utility model is equipped with pen core spring, Neutral ball-point for ball-point pen, a jumping bayonet lock successively, presses cap in a common jumping pen shell.Described Neutral ball-point for ball-point pen write the microsprings that the roof pressure ball is not set in the ferrule, the other end is provided with one section cavity, described cavity internal diameter is slightly larger than the internal diameter that Neutral ball-point for ball-point pen stores up black tube portion, the ball valve spring is housed in the cavity, the length of described ball valve spring is slightly larger than the length of cavity, diameter is slightly less than the cavity internal diameter and is slightly larger than the internal diameter that Neutral ball-point for ball-point pen stores up black tube portion, one end roof pressure is in the cavity inboard, can not slide to writing ferrule, the ball valve spring is under the situation of no external force, the cavity sub-fraction is extended in the other end, and ball valve is placed on it; Described ball valve push rod is connected to jumps a bayonet lock and presses cap inside, and one is provided with the spill pallet, the apical grafting ball valve, and the other end is supported to terminate in and is pressed crown end inside.Described ball valve is the silica gel ball, and its slightly larger in diameter is slightly less than in the cavity internal diameter and jumps a bayonet lock internal diameter; The length that the length restriction of described push rod is connected with ball valve at push rod is slightly larger than to jump a bayonet lock and press cap and patches together length.Be in when writing state at the utility model, jump a bayonet lock to the nib displacement, and location, a fixed gap is vacated on its top, presses cap and can freely separate with a jumping bayonet lock, thereby make the ball valve push rod can do displacement among a small circle, the ball valve spring pushes away ball valve the cavity of pen core, make the direct and atmosphere perforation of this end, the ink in the Neutral ball-point for ball-point pen can flow out freely writes ferrule, realizes writing function; Be in when not writing state, the pen core spring promotes the pen core indentation and jumps a pen shell, makes to jump a bayonet lock and press cap and be connected and lock together; The ball valve push rod holds out against ball valve in the cavity outside under the qualification of pressing cap, makes that this end is airtight, and in the effect of atmospheric pressure, the ink in the Neutral ball-point for ball-point pen can not flow freely, thereby reaches the purpose that the control ink flows.

The specific embodiment

Fig. 1 the utility model STRUCTURE DECOMPOSITION figure.

Fig. 2 the utility model inside is in the structure chart when not writing state.

Fig. 3 the utility model inside is in the structure chart when writing state.

The invention will be further described to engage accompanying drawing below:

Present embodiment is equipped with pen core spring 2, Neutral ball-point for ball-point pen 3 successively, jumps a bayonet lock 7, presses cap 8 based on the neutral pen of jumping of the comparatively common K35 type in market in a common jumping pen shell 1.Described Neutral ball-point for ball-point pen 3 write the trickle spring that the roof pressure ball is not set in the ferrule 9, the other end is provided with one section cavity 10, described cavity 10 internal diameters are slightly larger than the internal diameter that Neutral ball-point for ball-point pen stores up black tube portion, ball valve spring 4 is housed in the cavity 10, the summary length of described ball valve spring 4 is greater than the length of cavity 10, diameter is slightly less than the cavity internal diameter and is slightly larger than the internal diameter that Neutral ball-point for ball-point pen stores up black tube portion, one end roof pressure is in cavity 10 inboards, can not slide to writing ferrule 9, ball valve spring 4 is under the situation of no external force, cavity 10 sub-fractions are extended in the other end, and ball valve 5 is placed on it; Described ball valve push rod 6 is connected to jumps a bayonet lock 7 and presses cap 8 inside, and one is provided with the spill pallet, apical grafting ball valve 5, and the other end is supported to terminate in and is pressed inside, cap 8 top; Described ball valve is the silica gel ball, its slightly larger in diameter in cavity 10 internal diameters, be slightly less than and jump a bayonet lock 7 internal diameters; The length restriction of described ball valve push rod 6 exists: the length that ball valve push rod 6 is connected with ball valve 5 is slightly larger than to jump a bayonet lock 7 and press cap 8 and is adjacent to the length that patches together.

Be in when writing state at the utility model, jump a bayonet lock 7 to the nib displacement, and location, a fixed gap is vacated on its top, presses cap 8 and can freely separate with a jumping bayonet lock 7, thereby make ball valve push rod 7 can do displacement among a small circle, ball valve spring 4 pushes away cavity 10 with ball valve 5, make the direct and atmosphere perforation of this end, the ink in the Neutral ball-point for ball-point pen can flow out freely writes ferrule 9, realizes writing function; Be in when not writing state, pen core spring 2 promotes Neutral ball-point for ball-point pen 3 indentations and jumps in the pen shell 1, make to jump a bayonet lock 7 and press cap 8 and be connected and lock together, ball valve push rod 7 holds out against ball valve 5 in cavity 10 outsides under the qualification of pressing cap 8, make that this end is airtight, in the effect of atmospheric pressure, the ink in the Neutral ball-point for ball-point pen can not flow freely, thereby reaches the purpose that the control ink flows, guarantee that under the obsolete state of the utility model, ink is difficult for overflowing, volatilizing.

Because the utility model does not use microsprings, makes the cost of whole pen reduce greatly, to write Shi Buxu simultaneously and apply too big external force, the paper imagination is eaten in difficult generation, writes the ball difficult drop-off.
