CN2127662Y - New-type pen - Google Patents

Abstract

The utility model belongs to the technical field of stationery. The utility model is a pen whose use is more convenient and cleaner than the use of an existing pen. The middle part of the pen core of the pen is provided with a conduit pipe which opens onto a cavity. The back part of the conduit pipe is provided with a piston group. Ink is sucked in the cavity and is ejected into an external cavity with the drive of a pressing head at the tail part of the pen and the assistance of a spring. The inconvenience that when an existing pen sucks ink, the back sleeve of the pen and an ink bottle cover need to be screwed off is overcome by the technique. The problem that the existing ink absorption is insufficient is solved. The disadvantage that after the ink is sucked, the residual ink needs to be wiped by a soft cloth is avoided. Therefore, the utility model is an innovation body for an existing pen.

Description

New-type pen

It is a kind of a kind of pen than existing pen more convenient (only needing the compression suction), clean (need not to try erasable ink with cloth) that the utility model belongs to the cultural goods technical field.

At present, popular pen in the inside of the cap of a pen mainly by fountain pen nib, not only played support but also plastics chock plug, flexible conduit and the leather hose of evacuating ink of holding concurrently formed.After ink uses up in the pen, need outward winding and overlap and the ink bottle cover of outwarding winding behind the pen, compress spring leaf then, then nib is stretched in the bottle, make ink submergence fountain pen nib, compress spring leaf repeatedly, by atmospheric effect, ink is sucked in the leather hose, during suction, in fact fully suction can only be for the first time, later each all more or less with former hydraulic pressure in ink bottle, some idle works have been done, waste the time, after suction is good, taken out pen, wipe with soft cloth and to dip in dirty fountain pen nib, again cover behind the pen is screwed at last.

The purpose of this utility model provides a kind of pen, and it is not only easy to use, need not open pen back cover, and ink bottle cover only needs compression plastic sheath 9, just can be sprayed onto ink fully in the exocoel of storage ink, and after the suction, not need to wipe nib with soft cloth.

The purpose of this utility model is achieved in that

1, will have the flexible plastic tube that pen holds the storage ink now changes into plastic wrapper 11 storage inks.

2, with the duroplasts goods of trough of belt around the pen core 1(in the fountain pen nib) in the middle of drive a conduit, this pipe extends always, it is gradually big to have arrived the rear section diameter, and have one can seal continuous with it by the plastic piston group (12,13,14,15) that spring freely drives flexible (stroke is between 10mm--20mm), at spring and piston connecting place, designed a check valve (by up and down control of bead 13,14), ink can only be to a direction stream like this, and can not flow backwards, make each suction all fully effectively.

3, opened two all apertures all around the back a fraction of of piston, made the ink that comes from inner chamber be ejected into exocoel.

4, at compressible hip of the end of pen design, its active length has safeties (realizing insuring with bayonet socket) time spent not between plastics head 8 and the back cover 10 between 10mm--20mm, screw on dop, prevent that unexpected power from making ink excessive from fountain pen nib, time spent, the dop of outwarding winding.

When the utility model uses, earlier the flexible conduit on the ink bottle cover 16 is inserted in the conduit of pen pen core, after being seated, the insurance of pen back is opened, unclamp then by 9, because atmospheric effect, ink enters inner chamber, presses 9 again, and ink will spray into exocoel, connect by several times, after exocoel is full of ink, extract conduit 16, insure in the pass, ink when writing just derives from (amount of holding the storage ink in the exocoel is limited, prevents that ink is too much because the effect of deadweight makes ink overflow nib) in the exocoel.

The utility model is owing to adopt above-mentioned technical scheme, therefore have multiple functional, easy to use, cleaning, suction fully, the compression number of times is few, does not take the advantage of pen back cover, ink bottle cover apart.

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 2 is the composition detail drawing of plastic piston group

Fig. 3 is supporting with it ink bottle figure

Fig. 4 is insurance dop figure

Fig. 5 is I-I cutaway view of Fig. 1

Fig. 6 is II-II cutaway view of Fig. 1

Among Fig. 11, overlap 11 behind the head 9 of plastics pen core 2, pen nib 3, ferrule 4, spring 5, inner chamber 6, exocoel 7, plastics leather hose 8, band insurance, plastic sheath 10, plastics, the plastics protheca

Among Fig. 2 12, middle plastic products 13, plastic beads 14, plastic products 15, the plastic piston that connects

Among Fig. 3 16, flexible plastic tube 17, bottle cap 18, ink

In the embodiment shown in fig. 1, in overcoat 11 and 10, the perforate at pen core 1 middle part extends in postmedian to inner chamber has a spring 4 to be attached thereto, and the other end of spring 4 is tied mutually with a piston group.Piston 15 and pen core 1 sealing, drive at head 8, under the assistance of spring 4, piston 15 retractables (stroke is at 10mm--20mm), so whole system (piston group, 7,8,9) will move up and down, and under atmospheric effect, ink is sucked inner chamber, again at bullet spirt exocoel under the control of valve, thereby reach the effect of convenient absorbent.

As shown in Figure 2, be to draw on the existing scent sprayer of using commonplacely for the structural principle that this figure adopted.

As shown in Figure 3, flexible pipe 16 has an end to insert ink, and the other end is left the pen core conduit for and used.

Claims (5)

1, a kind of pen, in the cap of a pen, by nib inwardly be successively: fountain pen nib, pen core chock plug, flexible conduit and leather hose are formed, it is characterized in that: open a ductule at the middle part of pen core, the posterior part diameter is gradually big, and have one by spring drive the plastic piston group freely stretch seal with it continuous, thereby form inside and outside two chambeies, inner chamber is surrounded by pen core and piston, and exocoel surrounds after by pen core, piston, leather hose and pen.

2, pen according to claim 1 is characterized in that: in the piston group, establish a check valve, opened two all apertures around the piston rear portion.
