Description

The medical marking pen for conveniently changing core

Technical field

The utility model belongs to marking pen field, is related to a kind of medical marking pen for conveniently changing core.

Background technique

Hospital pathology department staff during the work time, needs to be recorded data with gel ink pen, fills up a document, while also needing Made a mark outside sample with marking pen, it is therefore desirable to carry at least two pens, use it is extremely inconvenient, therefore need Want it is a kind of can the pen write of both ends, one is thicker marking pen, and one is thinner writing pen, existing this kind of category It is various, but all have the following problems.

First is that pen is the integrated design, pen core or addition ink can not be replaced, can only abandon, cause serious after being finished The wasting of resources；Second is that although pen is seperated design, pen core or addition ink can be replaced, but replaces pen core or addition ink Inconvenience is easy ink to be stained with to hand or other places, both unhygienic or dangerous under this particular surroundings of hospital；Third is that Both ends usually share one-pen core with pen, because of usage amount difference, often will appear a providing ink and do not catch up with and can not write word, Other end can also write, if the pen renewed wastes very much, it is necessary to be equipped with one-pen again；Fourth is that such product hermeticity can be compared with Often there is new pen and have more than is needed the case where how long just can not writing word on pen core and nib in difference, the moisture evaporation and condensation in ink； Fifth is that such most penholder of product is relatively large in diameter, it is not easy to grasp when being write with writing end；Sixth is that mark nib is prone to wear and leads Causing ink to be also not run out can not just write, and overexert and also resulted in mark nib retraction pen sometimes, and mark nib is not Easy to install and replacement, causes to waste.

Summary of the invention

In order to overcome above-mentioned problems of the prior art, the purpose of the utility model is to provide it is a kind of it is split type, can Facilitating succinct replacement pen core and mark nib, both ends not to share, one-pen core, sealing effect is good, part convenient to grasp, economizes on resources The medical marking pen for conveniently changing core, solve problems of the prior art.

The utility model the technical scheme adopted is that a kind of medical marking pen for conveniently changing core include neutral pen cover, Neutral pen cap, Neutral ball-point for ball-point pen, penholder, mark pen core, mark nib, mark pen cover and mark pen cap.

Penholder inner hole described further is equipped with interlayer, and penholder inner hole is divided into cavity I and cavity II, I He of cavity by interlayer Cavity II is not communicated with.

Further mark pen core is set in cavity II, and center pen core is set to cavity I, neutral pen cap and mark pen cap point It is not movably connected on penholder both ends, neutral pen cover covers outside neutral pen cap, and mark pen cover covers outside marking pen.

Mark pen core described further is cylindrical body, and one end is equipped with installation fixation hole.

One end of penholder installation gel ink pen described further is equipped with tapering, and tapering and the angle of Neutral ball-point for ball-point pen center line are 10-25 degree.

Mark nib described further includes groove I, cone portion and writing portion, and groove I is arranged in writing portion and cone The connection in portion.

Mark pen cap inner hole described further is equipped with groove II and taper hole, and groove II connects to form channel with taper hole.

It is equipped with sealing ring between mark nib described further and mark pen cap, sealing ring is placed in groove I and groove II It is interior.

The utility model has the beneficial effects that the cavity I and cavity II that are set up separately by penholder, by Neutral ball-point for ball-point pen and marking pen On the other hand the problem of core thoroughly separates, and on the one hand can solve shared pen core forms split type structure, solve replacement pen core Problem must be arranged by the completely isolated and rubber washer and sealing ring of cavity I and cavity II, can further guarantee to remember The leakproofness of number pen, prevents the moisture of marking pen in-core from evaporating, the centrum portion of mark nib setting, can solve replacement mark nib The problem of, the tapering on penholder, which can solve, is not easy the problem of grasping.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

A kind of medical marking pen for conveniently changing core, including neutral pen cover 1, neutral pen cap 2, Neutral ball-point for ball-point pen 3, penholder 4, note Number pen core 5, mark nib 6, mark pen cover 7 and mark pen cap 8.

4 inner hole of penholder described further is equipped with interlayer 401, and 4 inner hole of penholder is divided into cavity I 402 and sky by interlayer 401 Chamber II 403, cavity I 402 and cavity II 403 are not communicated with, therefore can play the role of sealing, isolation.

Cavity I 402 described further is 3 installation site of Neutral ball-point for ball-point pen, and cavity II 403 is 5 installation position of mark pen core It sets, Neutral ball-point for ball-point pen 3 and mark pen core 5 are completely separated out by interlayer 401, do not share one-pen core to reach, and play two Kind pen core separates effect easy to change.

Mark pen core 5 described further be cylindrical body, one end be equipped with installation fixation hole 501, installation fixation hole 501 with every Layer 401 matches, and limits the position of mark pen core 5, on the one hand prevents the play in penholder 4 of mark pen core 5, on the other hand guarantees Mark 6 insertion depths of nib, to influence written 6 water absorbing properties of mark.

One end that penholder 4 described further installs gel ink pen is equipped with tapering 404,404 surface of tapering and 3 center of Neutral ball-point for ball-point pen The angle of line is 10-25 degree, and usual writing pen finger tip grip part is all relatively thin, and the setting in tapering 404 is straight in order to reduce penholder Diameter solves the grasping habit problem in user finger tip portion when being write with the neutral tip of the brushstyle of a writing or painting, user can be allowed more comfortably to write.

Mark nib 6 described further includes groove I 601, cone portion 602 and writing portion 603, and groove I 601 is arranged In the junction of writing portion 603 and cone portion 602, cone portion 602 can facilitate the installation and replacement of mark nib 6, during installation Guiding role is played, while insertion mark pen core 5 can be facilitated, increases contact area, thus better extracting liquid.

8 inner hole of mark pen cap described further is equipped with groove II 801 and taper hole 802, and groove II and taper hole 802 connect Channel is formed, taper hole 802 is consistent with the taper of cone portion 602, guiding when taper hole 802 plays installation and replacement mark nib 6 Effect, while play nib to mark 6 limit function, just can not inwardly be moved again after mark nib 6 is installed in place, because This avoids the situation in the written 6 retraction pens of mark.

It is equipped with sealing ring 10 between mark nib 6 described further and mark pen cap 8, sealing ring 10 is placed in groove I In 601 and groove II 801, on the one hand the setting of sealing ring 10 is the limiting device of mark nib 6, it can be prevented from marking pen It falls off in cap 8, on the other hand plays the role of sealing, reduce ink and contacted with the direct of air, prevent ink volatilization too fast.

Rubber washer 9 is equipped between penholder 4 and mark pen cap 8 described further, rubber washer 9 plays sealing function, After penholder 4 and mark pen cap 8 are tightened, rubber washer 9 can eliminate the gap between penholder 4 and mark pen cap 8, then by marking pen Lid 7 install to when position, rubber washer 9 can eliminate the gap between mark pen cover 7 and penholder 4 shown in Fig. 1, thus reach every Exhausted air, sealing effect.
