Description

A kind of reusable gel ink pen

Technical field

The utility model relates to a kind of ball pen, particularly relates to a kind of reusable gel ink pen.

Background technology

Gel ink pen is because it writes comfortable feel, and ink viscosity is lower, and increases easily lubricated material, write lubricated smooth, lines are even, so gel ink pen becomes a kind of writing implement being widely used.But existing refill of gel-ink pen is perfuse ink again, can only use once, not only waste resource, but also increased the weight of contaminated environment, also increased cost simultaneously.

The existing patent No. is that the Chinese utility model of CN201020115767.6 discloses a kind of two refill gel pens of China ink that fill, comprise pen container, pen container two ends are provided with the pen container head being flexibly connected with pen container, on pen container head, cover has the cap for brush, the length of the ink tube of pen core is not more than half of pen container length, nib is flexibly connected with ink tube one end, in ink tube, be placed with oil sealing, oil sealing is separated into ink cavity and air chamber by ink tube, device for charging ink is located on ink tube near written one end, the bottle mouth position of oil storage bottle is provided with filler pipe, and filler pipe matches with device for charging ink.Wherein, in device for charging ink, filling body stretches in ink cavity through ink tube, filling body is through one end sealing of ink tube, filling body stretches into an end opening of ink cavity, the blind end of filling body is provided with filler port, and filling inboard wall of tube body is fixedly connected with cone shaped spring one end, and shutoff plug matches with filler port by cone shaped spring.During filling ink, the filler pipe of oil storage bottle is inserted in the filler port of filling body, the bottle of extruding oil storage bottle, cone shaped spring externally shrinks under the effect of pressure, then drives shutoff plug to retreat, shutoff plug leaves filler port, ink flow in filling body from oil storage bottle, in refueling process, after oil sealing, moves, the balance that has kept ink tube inner and outer air pressure, to avoid ink excessive; After having annotated, extract the filler pipe of oil storage bottle out filler port, external pressure disappears, and cone shaped spring restores to the original state, and drives shutoff plug again to block filler port.This utility model is offered through hole by the bottle mouth position at oil storage bottle, and the method that is provided with filler pipe on this through hole provides a kind of two refill gel pens of China ink that fill.But on the one hand, the filler pipe internal structure of this utility model is complicated, on the other hand, thereby the sealing of filler pipe is to utilize spring extruding shutoff plug to block filler port, when sealing-plug adopts the material of larger hardness, the sealing property that is unfavorable for filler port, when sealing-plug adopts the good material of toughness, can deform by the extruding of spring, the stability of impact sealing, simultaneously, because spring has elasticity, gel ink pen is subject in the situation of high vibration, easily there is strain in spring, thereby affected sealability, in addition, because the tube wall of ink tube is excessively thin, filler pipe is direct like this to be stretched in ink cavity through black oil pipe, filler pipe is when being subject to clashing into, be easy to make filler pipe to depart from from ink tube, cause loss of seal ability.To sum up, adopt this hermetically-sealed construction to realize effective must sealing to ink, especially for viscosity and the less ink of granularity.

Utility model content

The technical problems to be solved in the utility model is the present situation for prior art, and a kind of reusable gel ink pen of simple in structure, good sealing effect is provided.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of reusable gel ink pen, comprise pen core, pen container, pen container head and the cap for brush, described pen core comprises black oil pipe, is arranged on the nib of described black oil pipe one end, is arranged on the ink in described black oil pipe and is arranged on the Seal Oil on described ink, it is characterized in that: pen container and pen container head are integrated part, the cap for brush and pen container screw thread are movably connected; Offering closed hole near on written black oil pipe, on described closed hole, be provided with sealing-plug.

As improvement, described closed hole is through hole, on described through hole, is provided with protuberance, on described protuberance, is provided with screwed hole, and described screwed hole communicates with described through hole and the aperture of described screwed hole is greater than the diameter of described through hole; Described sealing-plug comprises the stick harness and the boss that is connected in described stick harness with described screwed hole threaded engagement.By protuberance is set, thereby increased the length of closed hole, improved sealability and sealing-plug and be attached to the reliability on black oil pipe; In addition, adopting is threaded relatively and is slidably connected has increased the path that ink leaks outside, and improves sealability.

Improve, on the lateral surface of described protuberance, centered by the center of described screwed hole, be provided with counter sink, on the boss on described sealing-plug, be provided with inner hexagonal hole, the boss of described sealing-plug is lower than described counter sink or concordant with described counter sink.By arranging, be applicable to the counter sink that the boss of sealing-plug is located on protuberance, thereby reduced the outward extending length of required protuberance, to be conducive to control the external diameter size of pen container, on the boss of sealing-plug, inner hexagonal hole to be set, facilitated the screw-in of sealing-plug simultaneously.

Improve, described pen container comprises left pen container and right pen container again, and described left pen container and described right pen container are flexibly connected.Pen container is made after Split type structure, can directly the cap for brush and pen container be made of one, reduced the quantity of parts, reduce costs.

Improve, described left pen container comprises inside tapered thread again, and described right pen container comprises outer cone thread, and described left pen container and described right pen container are fixed by described inside tapered thread and described outer cone thread screw thread.The relative regular screw threads structure of structure of taper thread can increase left and right pen container at the thickness of connecting portion, makes to connect more reliable.In addition, at the center of the end face of the described outer cone thread of described right pen container, offer pilot hole, described pilot hole diameter is identical with the external diameter of described black oil pipe.By pilot hole is set, black oil pipe is played to position-limiting action in middle part, reduce the possibility that nib rocks in writing process.

Improve, described left pen container comprises a Plug Division again, and described Plug Division inwall is provided with groove; Described right pen container comprises an insertion section, and described insertion section outer wall is provided with the projection fastening with described groove.For the movable connection method of the left and right pen container of another kind, the pulling out of left and right pen container, slotting connected mode have been realized.

Improve, the external diameter size of left pen container and right pen container is identical again.Left and right pen container size is made identical, made a both hands compact conformation, good visual effect, meet traditional pen holding habit simultaneously.

Compared with prior art, owing to the utility model has the advantage of: by the form of closed hole and sealing-plug, greatly simplified the hermetically-sealed construction of the through hole of original black oil pipe.When gel ink pen is used by sealing-plug plug on closed hole, prevent that ink from flowing out; While needing refilling, sealing-plug is taken off, the syringe needle by ink syringe pierces in through hole, realizes ink inject by the impressed pressure of ink syringe, after completing, directly sealing-plug is got back into.
