Description

Efficient portable fountain pen capable of replacing pen core

Technical Field

The utility model relates to a stationery technical field, more specifically says that it relates to refill replacement efficient portable water pen.

Background

At present, in life, work and study, the application range of gel-ink pens is the most extensive, and gel-ink pens on the market have a plurality of models, but the common point is that the pen shell is a hollow cylinder, and the pen shell is opened in a threaded connection mode and then is put into a pen core.

The replacement of the pen core in the gel ink pen in the prior art is an inconvenient matter, and the pen head needs to be screwed out of the pen shell, a new pen core is inserted after the original pen core is pulled out, and the pen head is screwed into the pen shell to complete the fixation; meanwhile, the pen point is small in size and is often easy to lose in the replacement process, so that the pen shell cannot be used.

Therefore, a new solution is needed to solve this problem.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a refill replacement efficient portable water pen limits and fixes the nib end of refill through the joint between first connecting block and the second connecting block on the casing, just can follow first logical groove roll-off with first connecting block and second connecting block separation back former refill when needs are replaced to the refill, puts into and fixes the completion refill replacement that just can be quick with new refill this moment.

The above technical purpose of the present invention can be achieved by the following technical solutions: efficient portable water pen is replaced to refill, be equipped with the refill that supports the piece and overlap and be equipped with the rubber sleeve including casing and bottom, be equipped with first logical groove on the both ends of casing, casing bottom both sides are the first connecting block of fixedly connected with and second connecting block respectively, fixedly connected with fixture block on the first connecting block, be equipped with the draw-in groove that supplies the fixture block card to go into on the second connecting block, offer on first connecting block and the second connecting block and be used for putting into support the chamber of placing of piece.

By adopting the technical scheme, after the first connecting block and the second connecting block on the shell are disassembled, the placing cavity is exposed, the refill is pushed into the pen shell through the arrangement of the first through groove, and the first connecting block and the second connecting block are respectively pushed after the abutting block on the refill is placed in the installing cavity, so that the clamping block and the clamping groove can be clamped and the refill can be fixed; when the refill is replaced, the first connecting block and the second connecting block are separated, and then the shell is rotated, so that the first through groove is in a vertical state, the refill naturally falls off from the shell due to gravity, and the refill is convenient to replace; the placing groove limits the abutting block to prevent the pen core from sliding in the pen shell to influence writing.

The utility model discloses further set up to: and a first groove is formed in one side, far away from the top end of the shell, of the first connecting block and the second connecting block, and the diameter of the first groove is the same as that of the rubber sleeve.

By adopting the technical scheme, the first groove is used for being clamped into the rubber sleeve, and the rubber sleeve arranged on the pen core is mainly used for preventing ink from leaking from the front end due to air pressure at the tail of the pen and protecting the ball head at the front end of the neutral pen; after the pen core is installed on the shell, the front end of the pen core is still protected by the rubber sleeve, the pen core is well protected, and meanwhile, the material utilization rate can be improved.

The utility model discloses further set up to: the top end of the shell is rotatably connected with a baffle which is annular, a second through groove with the width consistent with that of the first through groove is formed in the baffle, and a friction strip is arranged on the outer surface of the baffle.

By adopting the technical scheme, the baffle rotationally connected with the top end of the shell is used for limiting the tail end of the pen core placed in the shell, so that the situation that the tip end of the pen core is stressed and the tail end is influenced to slightly swing in the writing process is avoided, the swinging range of the pen core can be greatly reduced after the tail end of the pen core is limited, and meanwhile, the tip end of the pen core can be slightly supported; the friction strips are arranged to facilitate the rotation of the baffle at the outer side, and the pen core can be normally taken out after the baffle rotates to the coincidence of the first through groove and the second through groove.

The utility model discloses further set up to: the shell is made of polymethyl methacrylate, and a plurality of reinforcing ribs are fixedly connected in the shell.

By adopting the technical scheme, the polymethyl methacrylate has better chemical stability and weather resistance, and meanwhile, the safety can be ensured due to the characteristics that the polymethyl methacrylate is not easy to break and the broken polymethyl methacrylate does not cut hands; the arrangement of the reinforcing ribs further improves the supporting strength of the shell, so that the shell is more difficult to break.

The utility model discloses further set up to: the shell is connected with a holding part in a sliding mode, and a supporting plate used for limiting the position of the holding part is arranged on the shell.

By adopting the technical scheme, the arrangement of the holding part can improve the writing feeling of a user, and the user holds the holding part to write after holding the shell; the arrangement of the abutting plate can improve the friction force between the holding part and the shell, and avoid the situation that the holding part can not be used for writing due to easy sliding in writing; when the refill is to be replaced, the first through groove can be exposed by sliding the holding part to the topmost end.

The utility model discloses further set up to: the shell is provided with a first sliding groove for the sliding connection of the holding part, the baffle is provided with a second sliding groove, and when the baffle rotates to the first through groove and the second through groove to be overlapped, the first sliding groove is communicated with the second sliding groove.

Through adopting above-mentioned technical scheme, first spout and second spout all are used for the slip of the portion of gripping, and the baffle will rotate the baffle when needing the replacement refill and make first logical groove and the coincidence of second logical groove, and first spout and second spout can switch on each other this moment for the portion of gripping can promote to the outside, and the refill just can be quick installation and replacement work after the portion of gripping is promoted to the outer end.

The utility model discloses further set up to: the casing top is equipped with the installation cavity, rubber sleeve joint in the installation cavity.

Through adopting above-mentioned technical scheme, the setting up of installation cavity will be convenient to accomodate rubber sleeve memorability, avoids the rubber sleeve can lose easily and then can't protect the refill point end.

To sum up, the utility model discloses following beneficial effect has:

the clamping between first connecting block and the second connecting block on through the casing restricts and fixes the piece of supporting on to the refill, just can follow first logical groove roll-off with first connecting block and second connecting block separation back former refill when replacing the refill, this moment with support the piece put into on the new refill place the chamber after just can accomplish the installation of refill laminating first connecting block and second connecting block, then will grip the portion of pushing down to support board department and restrict just can write again, promoted replacement speed by a wide margin and can also avoided the part to lose and lead to the unable use of pen shell.
