Abstract
The utility model discloses a reusable pen core, which comprises an ink oil tube, a pen head arranged at one end of the ink oil tube, ink arranged in the ink oil tube and sealing oil arranged on the ink and is characterized in that a seal hole is formed in the ink oil tube and in a position close to the pen head; a sealing plug is arranged on the seal hole. According to the utility model, the sealing to the seal hole is realized by using the sealing plug and the reusable pen core which is low in cost and convenient to assemble is provided.
Description
Technical field
The utility model relates to a kind of pen core, particularly relates to a kind of reusable pen core.
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 CN200320111310.8 discloses a kind of black Neutral ball-point for ball-point pen that fills, comprise nib, connector and oil pipe, its improvement is on the oil pipe of the top of this connector, to open one can fill black hole, having a button plug and be connected with botton-plug belt and be bonded on oil pipe correspondingly, is plugged with tail plug at the end of oil pipe.This utility model additionally increases botton-plug belt, and botton-plug belt is bonded in to the operation on oil pipe, increased processing cost, wherein when botton-plug belt is bonded on oil pipe, need strictly to be alignd with the hole on botton-plug belt in the hole on oil pipe, otherwise have a strong impact on sealing effectiveness, increased the difficulty of this operation, increased labour cost; In addition, between oil pipe and botton-plug belt, have and the bonding not firm phenomenon that easily occurs that ink leaks outside.
Utility model content
The technical problems to be solved in the utility model is the present situation for prior art, and the reusable pen core that a kind of cost is low and be convenient to assemble is provided.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of reusable pen core, comprise black oil pipe, be arranged on described black oil pipe one end nib, be arranged on the ink in described black oil pipe and be arranged on the Seal Oil on described ink, it is characterized in that: 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, described sealing-plug comprises the stopper being sealed and matched with described through hole and is connected in the boss of described stopper, at the described ink tube place near described nib, be provided with protuberance, described protuberance is provided with counter sink, described through hole runs through described protuberance and is positioned at described counter sink center, and described boss is placed in described counter sink.Wherein, described through-hole diameter is preferably 1mm～3mm, and through-hole diameter is 2mm more preferably.
Improve, described sealing-plug adopts silica gel material manufacture to form again.Sealing-plug adopts silica gel material to make, and utilizes the tension force of silica gel material to make sealing-plug coordinate more firmly with black oil pipe, thereby further improves sealing.
As another scheme of closed hole, described closed hole is screwed hole, and described sealing-plug comprises the stick harness and the boss that is connected in described stick harness with described screwed hole threaded engagement.Employing is threaded relatively and is slidably connected and increased the path that ink leaks outside, and improves sealability.
As improvement, near on the black oil pipe of described nib, be provided with protuberance, described screwed hole connects to this protuberance.By protuberance is set, thereby increased the length of screwed hole, improved sealability and sealing-plug and be attached to the reliability on black oil pipe.
Improve, on the protuberance on described black oil pipe, 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 the pen cap, on the boss of sealing-plug, inner hexagonal hole to be set, facilitated the screw-in of sealing-plug simultaneously.
The third scheme as closed hole, described closed hole is through hole, on described through hole, be provided with protuberance, on described protuberance, be provided with screwed hole, described screwed hole communicates with described through hole and the aperture of described screwed hole is greater than the diameter of described through hole, on the lateral surface of described protuberance, centered by the center of described screwed hole, is provided with counter sink; Described sealing-plug comprises with the stick harness of described screwed hole threaded engagement, is connected in the boss of described stick harness and extended and described through hole coordinates on described stick harness projection, on 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.Utilize the projection first to block the through hole on black oil pipe, thereby reduced quantity and ability that ink enters the screw thread section of screwing, more effectively must improve sealability.
Compared with prior art, owing to the utility model has the advantage of: directly adopt the mode of sealing-plug to seal closed hole, make hermetically-sealed construction relatively simple, reduced the parts of sealing use, reduce the matching requirements of pen core, thereby reduced the processing cost of pen core.
