Abstract

The utility model belongs to the technical field of the stationery, in particular to pearl pen is walked to straight liquid formula. This pearl pen is walked to straight liquid formula includes nib and pen -holder, establishes the refill in nib and pen -holder, connects annular limiting plate on the lateral wall of pen -holder top, establishes the enclosing cover at the pen -holder top cover in the annular limiting plate outside, connects annular boss in enclosing cover inside bottom, and it is continuous that the inboard of annular boss and pen -holder top outer wall pass through the screw, connect the round bar on enclosing cover inside top, the round bar outer wall passes through the screw thread with pen -holder top inner wall and links to each other, corresponds the refill top in the round bar bottom and establishes circular recess, sets firmly the rubber pad on circular recessed wall, and the top of refill links to each other with the rubber pad butt, the through -hole of the vertical setting that one about link up is equipped with at enclosing cover middle part. This pearl pen is walked to straight liquid formula can freely adjust according to the length of refill, and the refill after avoiding changing is provided convenience for the user because improper can't the placing of length is used in the pen -holder.

Description

A kind of direct-liquid type ball-point pen

(1) technical field

The utility model belongs to stationery technical field, particularly a kind of direct-liquid type ball-point pen.

(2) background technology

Existing direct-liquid type ball-point pen in use, because frequency of utilization is higher, often need to change pen core, but pen core market being applicable to the use of direct-liquid type ball-point pen is various, often occurs buying back oneself favorite pen core, but be but not suitable for the penholder of direct-liquid type ball-point pen, longlyer or too short than penholder to rock in penholder, cannot use, bring worry to user.

(3) summary of the invention

The utility model is in order to make up the deficiencies in the prior art, provide a kind of rational in infrastructure, convenient and practical direct-liquid type ball-point pen, can according to the length free adjustment of pen core, avoid the pen core after changing because improper cannot being placed in penholder of length uses, providing convenience to user, for regulating the enclosing cover of length not depart from penholder in use procedure, using flexibly, and avoid loss, solve problems of the prior art.

The utility model is achieved by the following technical solution:

A kind of direct-liquid type ball-point pen, the penholder comprising nib and be connected with written screw thread, a pen core is provided with in nib and penholder inside, the lateral wall on penholder top connects a horizontally disposed annular stop plate, the sheathed enclosing cover in penholder top outside annular stop plate, connect an annular boss arranged along penholder circumferential direction in the bottom of enclosing cover inside, the inner side of described annular boss is connected by screw thread with penholder top exterior walls; The round bar that penholder inside is stretched in a lower end is connected on the top of enclosing cover inside, round bar outer wall is connected by screw thread with penholder top inner wall, in round bar bottom, corresponding pen core top is provided with a circular groove, and circular groove inwall sets firmly a rubber blanket, and the top of described pen core abuts with rubber blanket and is connected; The through hole of the vertical setting of a up/down perforation is provided with in the middle part of enclosing cover.

The beneficial effects of the utility model are: this direct-liquid type ball-point pen passes through screw thread sheathed connection one enclosing cover in the outside on penholder top, the annular boss that enclosing cover inner lower edge is arranged is connected with penholder top exterior walls by screw thread, the round bar that a bottom and pen core top abut against is provided with in enclosing cover middle inside, and round bar outer wall is threaded with penholder top inner wall, this structural design fully can meet the flexible up-down adjustment of penholder to different length pen core.Owing to connecting an annular stop plate on the lateral wall on penholder top, can avoid that pen core is longer, enclosing cover produces penholder top and drop or lose when penholder top orientation rotates and regulates.Be provided with rubber blanket in circular groove due to round bar bottom, firmly, not rock when can ensure that pen core top fixes in circular groove, conveniently to write.

(4) accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the longitudinal sectional structure schematic diagram of Fig. 1.

In figure, 1 nib, 2 penholders, 3 pen cores, 4 annular stop plates, 5 enclosing covers, 6 annular boss, 7 round bars, 8 circular grooves, 9 rubber blankets, 10 through holes.

(5) detailed description of the invention

For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in accompanying drawing 1-2, the penholder 2 that this direct-liquid type ball-point pen comprises nib 1 and is connected with written 1 screw thread, a pen core 3 is provided with in nib 1 and penholder 2 inside, the lateral wall on penholder 2 top connects a horizontally disposed annular stop plate 4, the sheathed enclosing cover 5 in penholder 2 top outside annular stop plate 4, connect an annular boss 6 arranged along penholder 2 circumferential direction in the bottom of enclosing cover 5 inside, the inner side of described annular boss 6 is connected by screw thread with penholder 2 top exterior walls; The round bar 7 that penholder 2 inside is stretched in a lower end is connected on the top of enclosing cover 5 inside, round bar 7 outer wall is connected by screw thread with penholder 2 top inner wall, in round bar 7 bottom, corresponding pen core 3 top is provided with a circular groove 8, circular groove 8 inwall sets firmly a rubber blanket 9, and the top of described pen core 3 abuts with rubber blanket 9 and is connected; The through hole 10 of the vertical setting of a up/down perforation is provided with in the middle part of enclosing cover 5.

In use procedure, when direct-liquid type ball-point pen needs to change old pen core, rotate nib 1 to back out from penholder 2, take out the old pen core be finished, the pen core 3 bought is inserted along penholder in the rubber blanket 9 connected in the circular groove 8 of round bar 7 bottom, can according to pen core 3 length judged in advance, prior rotation regulates enclosing cover 5 to be connected to facilitate pen core 3 top to abut with rubber blanket 9 easily, nib 1 is enclosed within pen core 3 lower end and rotates with penholder 2 and tighten, now can regulate enclosing cover 5 the assurance second time of pen core 3 length according in nib 1 and penholder 2 rotation process: when nib 1 and penholder 2 are not yet tightened with regard to turning motionless, enclosing cover 5 can be rotated along penholder 2 to penholder top, when nib 1 and penholder 2 tighten that pen core 3 but exposes less time, enclosing cover 5 can be rotated in the opposite direction along penholder 2.Because round bar 7 outer wall and penholder 2 top inner wall are also threaded connection, can strengthen the pen core steadiness in the use procedure of direct-liquid type ball-point pen further, what prevent from pen core from rocking causing writes inconvenience.

The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
