Abstract

The utility model discloses a white board pen comprising a pen head, a pen cap, a pen mouth, a pen canister, and a back cover; the utility model adopts a valve rod device for ink providing, and a anticlockwise screw thread connection is adopted between the pen mouth and the pen canister, thus opening the pen mouth by accident due to a habit action which causes outward flow of the ink can be prevented. An ink storing bin is arranged at the pen mouth; a cross protruding rib is arranged on the top of the pen cap and inserted into the back cover as a screwdriver; the utility model solves the problem of easy volatilization when the white board pen is not in use, and has the advantages of good seal, easy assembly and disassembly, large writing amount, free from fatigue, application for repeated use, and saving the raw material.

Description

The blank pen

Technical field

The utility model relates to a kind of writing implement, specifically a kind of blank pen.

Background technology

The blank pen of people's use at present is to adopt the storage device of disposable cotton core as ink basically, and memory space is little, and sealing is poor, and ink is volatile when not writing, and the mounting or dismounting difficulty can not be reused, and causes raw material to waste in a large number.Also have and adopt the valve mechanism ink supply, but need constantly press nib, to guarantee ink without interruption, easily produce wrist fatigue.

Summary of the invention

The purpose of this utility model just provides a kind of blank pen, and is poor to solve original blank sealing, mounting or dismounting difficulties, problem such as wrist fatiguability in the time of can not reusing and write for a long time.

The purpose of this utility model is achieved in that a kind of blank pen, by nib, the cap for brush of sealing nib, a mouth of fixing nib, the pen container that is connected with a mouth, the bonnet of sealing pen container end is formed, it is characterized in that: the taper type valve bonnet of the promising one of pen container front end, have into black window on the valve bonnet, valve rod one end is inserted in spring and inserts the valve bonnet top, valve seat is inserted in from the valve rod other end that inserts nib, and the tight fit device is at the valve bonnet end; Mouth front end is placed sponge, and nib is passed from the hole in the middle of the sponge, exposes outside the mouth, and a mouth is threaded on the pen container counterclockwise, valve seat outer surface and sponge between leave ink storing chamber.

There is link to each other with the pen container inwall hollow cylinder of the outstanding pen container rear end face of the other end of an end rear end of described pen container.

There is the cross garden muscle of evagination symmetrical mounting described cap for brush end, has a convex tendon parallel with cap for brush axis and one to be positioned at the convex tendon that cap for brush reducing position and this convex tendon intersect vertically at afterbody.

There is circular groove on described bonnet top, has the cross garden groove that is complementary with cross garden muscle in the groove, and the corresponding bonnet of groove inside is plug in the sphere identical with the hollow cylinder internal diameter.

Good effect of the present utility model is: owing to taked said structure, open ink channel when writing under pressure, ink flows out automatically, be temporarily stored in the ink storing chamber, do not need to push for a long time nib, the amount of writing is big, no wrist sense of fatigue, ink channel is closed automatically when not writing, and good airproof performance, ink are not volatile, and it is for convenience detach, repeatedly the can ink is reused, and saves raw material.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is that the utility model is write longitudinal sectional drawing under the state,

Fig. 2 is a cap for brush front view of the present utility model,

Fig. 4 is the vertical view of Fig. 1

Among the figure, 1, bonnet, 2, groove, 3, interior plug, 4, hollow cylinder, 5, pen container, 6, valve rod, 7, valve bonnet, 8, advance black window, 9, spring, 10, valve seat, 11, a mouth, 12, sponge, 13, nib, 14, cross garden muscle, 15, the cap for brush, 16, convex tendon, 17, convex tendon, 18, the garden groove.

The specific embodiment

As Fig. 1, Fig. 2, shown in a kind of blank pen described in the utility model, by the nib 13, the cap for brush 15 of sealing nib, a mouth 11 of fixing nib, the pen container 5 that is connected with a mouth, the bonnet 1 of sealing pen container end is formed, the taper type valve bonnet 7 of the promising one of pen container 5 front ends, have four on the valve bonnet 7 and advance black window 8, the interior ink of pen container can be entered, valve rod 6 one ends are inserted in spring 9 and insert valve bonnets 7 tops, valve seat 10 is inserted in from valve rod 6 other ends that insert nib 13, and the tight fit device is at valve bonnet 7 ends; Mouth 11 front ends are placed sponge 12, and nib 13 is passed from the holes in the middle of the sponge 12, expose outside the mouth, the outer surface of valve seat 10 and sponge 12 between leave ink storing chamber.When writing, nib pressure makes the spring compression, ink flows out from the gap between valve rod 6 and the valve seat 10, the ink storing chamber of flowing through is penetrated into nib 13 to sponge 12, ink can temporarily be filled in ink storing chamber, do not need to press for a long time nib 13, the amount of writing is big, alleviate the sense of fatigue when writing, mouth 11 is threaded on the pen container 5 counterclockwise, prevent from habitually to move and open by mistake a mouth, link to each other with the pen container inwall hollow cylinder 4 of the outstanding pen container rear end face of the other end of an end is arranged in the rear end of pen container 5, to strengthen the sealing with bonnet 1.

As Fig. 2, shown in Figure 3: there is the cross garden muscle 14 of evagination symmetrical mounting the cap for brush 15 ends, there are a convex tendon parallel 17 and one to be positioned at the convex tendon 16 that cap for brush reducing position and this convex tendon intersect vertically at afterbody,, are convenient to hold the cap for brush to increase frictional force with cap for brush axis.

As Fig. 2, Fig. 4, shown in: there is circular groove 2 on bonnet 1 top, have the cross garden groove 18 that is complementary with cross garden muscle 14 in the groove, so that the cross garden muscle 14 on the cap for brush 15 inserts, as the smooth bonnet 1 of turning on of screwdriver, groove 2 corresponding bonnet inside are plugs 3 in the sphere identical with hollow cylinder 4 internal diameters, have improved the sealing with pen container 5, prevent that ink from oozing out from bonnet 1.
