Abstract

The utility model relates to a double-ended valve pen, wherein, a penholder (6) is filled with ink (13), both ends inside the penholder (6) are provided with a stop valve, a valve cover (10) is plugged and fixed on the head part of a valve body (5), the end of a center hole has a taper and takes the shape of a cone, a valve core (11) is positioned inside the valve body (5) and supported by a spring (12), a corresponding conical surface is arranged corresponding to the end of the center hole of the valve cover (10), the end of the pen point (8) is inserted into the center hole of the valve cover (10) and balanced out with the head of the valve core (11). When using the utility model, the pen point (8) is pressed gently and then the valve core (11) is pushed back at once, the ink (13) flows smoothly from the center hole of the valve cover (10) into the pen point (8), and the flow rate increases with the strength of pressing the pen point (8).

Description

A kind of double end valve pen

The utility model relates to a kind of valve-type lettering pen.

Existing fluorescence, mark, blank pen etc. adopt the lettering pen of fiber nib, the structure of its providing ink adopts rolled core more, the supply of its ink is to realize by being arranged on the liquid reservoir internal cavities and being full of the hygroscopicity filler that contains ink, such structure will certainly make the supply of ink very slow, and is smooth and easy inadequately and can not control flow; Because its ink is to ooze in the rolled core of being made by the hygroscopicity filler, so the ink reserves are few and easy evaporation, the storage and the service life of pen are all shorter.

The purpose of this utility model provides the valve-type that a kind of providing ink is smooth and easy and flow is adjustable lettering pen with regard to being at above-mentioned prior art present situation, and storage China ink amount is big, and the storage and the service life of pen improve greatly.

The purpose of this utility model is achieved in that the valve-type lettering pen comprises the penholder and the two ends nib of sealing, be filled with ink in the penholder, it is characterized in that the big or small end positions in the penholder is equipped with the stop valve of being made up of spool, valve body, valve gap, the afterbody of solid its medium pore of port part at valve body of valve gap plug has tapering and is truncated cone-shaped, spool is positioned at valve body and is supported by spring, and have in its corresponding conical surface corresponding to valve gap medium pore port position, described written afterbody inserts described valve gap medium pore and offsets with described spool bore bottom.

In order to protect written head, prevent the evaporation of ink in the penholder, also can respectively be with a pen cap at the two ends of penholder simultaneously for the ease of carrying and using.

Compared with prior art, the utility model in use, as long as depress written head gently, spool promptly is pushed rearward, ink will be swimmingly flow to nib from the medium pore of valve gap; Flow is along with the strength that presses down nib increases and increases, and after unclamping, nib is protracted under the effect of its returning spring and blocked the medium pore of valve gap.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 5, double end valve-type lettering pen comprises Packed penholder 6 and big end nib 8, is provided with in the upper half of the big end of penholder 6 and connector 7 close-fitting sealed attachment parts by valve body 5, big valve core 11, the big stop valve that constitutes of valve gap 10 greatly.Valve body 5 and the sealing of connector close-fitting, the upper end of valve body is the hollow out body, the solid lower end of big valve gap 10 plugs at valve body, the afterbody of its medium pore has tapering and is truncated cone-shaped, and big valve core 11 is positioned at valve body 5, has a step in the middle of it, one spring, 12 covers therein, one end withstands on this step, and the other end withstands on the afterbody of valve body 5, and has the conical surface corresponding with it corresponding with the position of valve gap 10 medium pores.Described big written 8 heads are exposed to outside the connector 7, and its afterbody inserts described big valve gap 10 medium pores and offsets with described big valve core 11 heads through connector 7, and described big written 8 have a flat head 81 that is duck tongue shaped.

The other end of penholder is provided with the little stop valve that is made of same valve body 5, small valve core 4, little valve gap 3.Valve body 5 and the sealing of penholder 6 small end close-fittings; The solid other end of same little valve gap 3 plugs at valve body 5, its tail end central authorities have tapering and are truncated cone-shaped, small valve core 4 is positioned at valve body 5, has a step in the middle of it, same spring 12 covers therein, one end withstands on this step, and the other end withstands on the afterbody of valve body 5, and has the conical surface corresponding with it in the position corresponding to little valve gap 3 medium pore ports.Described little written 2 heads are exposed to outside the small end of penholder 6, and its afterbody inserts described little valve gap 3 medium pores and offsets with described small valve core 4 heads through the small end of penholder 6.The interlude of penholder promptly comprises that the hollow out body portion of two valve bodies 5 is full of ink 13 between two valves.The material friendship of size nib adopts hygroscopic materials, is good with high-density polyethylene.

9 is the big pen cap among the figure, and 1 is the little pen cap.The purpose of its setting all is to use and storage in order to protect big or small nib 8 and 2 to prevent the evaporation of ink in the penholder, also to be easy to carry simultaneously.
