Abstract

The utility model provides a pen for writing on boards, which is a writing tool for substituting for a chalk. Various coloured ink can be poured in the pen for writing on plates and the ink supply a fibre nib for writing on the boards through a special designed overflow valve. The utility model has fluent writing and clear handwriting. Thin-line patterns can be obtained by writing lightly and thick-line patterns can be obtained by writing heavily. The utility model overcomes the defects of inhomogeneous ink supply and easy block of the ink of the existing writing pen and achieves really practicality. The handwriting written by the pen for writing on boards is easy for wiping and no pollution of powder dust. Paint ink can be loaded for writing painting words.

Description

Pen writing on plate

The utility model relates to a kind of writing implement, particularly a kind of writing on the blackboard pen.

(flow out by aperture 2～4.5mm) through a precursor aperture for the ink of utility model patent " dustless liquid chalk " (patent No. 93221803.2), pen is horizontal when writing blackboard, ink can not get the gravity effect and can not flow, and the particle deposition that ink has stops up and is difficult to overcome.Utility model patent " blackboard lettering pen " (patent No. 93204451.4), its nib is bearing on a free spring and sponge ring and the nib, free spring is subjected to the slight power of nib and moves, and nib can't be located when writing, and ink also can be deposited on the sponge and easily stop up.

The purpose of this utility model provide a kind of simple in structure, write conveniently, the Pen writing on plate of economy and durability, it can replace chalk Free Writing onboard, no dust pollution is convenient and practical.

The technical solution of the utility model is: agitator 5 in pen container 4, pen container 4 opening termination valve seats 6, spring 7 is enclosed within the spool 8, spool 8 is enclosed within again in the valve body 9, valve body 9 is connected with valve seat 6, fiber nib 2 is enclosed within valve body 9 and the spool 8.In the pen container 4 the can water-base inks Pen writing on plate, substitute chalk, no dust pollution; The charge of oil ink becomes painting pen again.Fiber nib 2 is to be formed by bondings such as staple fibres.The pen container 4 and the pen cap 1 are oblate.Spool 8 has outer side slot, and the center is porose.

Advantage of the present utility model is to use fiber nib 2, overflow valve 3 and agitator 5 to form ink supply system.Ink is under the stirring of the overflow effect of fiber nib 2 capillarities, overflow valve 3 and agitator 5, avoided the inhibition of power and vacuum and fluent writing, and can prevent the deposition and the obstruction of ink, and overcome the deficiency of other plate lettering pen, really reached simple in structure and convenient and practical.The oblate pen cap 1 and pen container 4 make Pen writing on plate be difficult for rolling.

Describe in further detail below in conjunction with accompanying drawing.

Figure is a structural representation of the present utility model.

On overflow valve valve body 9, valve body 9 is threaded with valve seat 6 pen cap 1 by friction sleeve, and valve seat 6 is bonded in pen container 4 openends, dress ink and agitator 5 in the pen container 4.Spring 7 is enclosed within the spool 8, and spool 8 is enclosed within again in the valve body 9, and spool 8 has outer side slot, and the center is porose.Fiber nib 2 light skewers are gone in valve body 9 and the spool 8.Taking off the pen cap 1 during use can write by plate.Generally speaking, by entering in the pen container 4 in the valve seat 6, a route spool 8 centre bores enter in the fiber nib 2 ink by the hole on the valve seat 6, another road through the overflow of spool outer side slot to nib 2 outsides.If write thick stroke, or press fiber nib 2 during ink cartridge low, make it withstand spool 8 compression springs 7, Open valve, ink just can flow to fiber nib 2 outsides from the outer side slot of spool 8.When body is hanged down, can shake pen container 4, after agitator 5 work, ink is just even.When changing fiber nib 2, as long as extract oldly, skewer is gone into new getting final product.

Fiber nib 2 can form with bondings such as staple fibres, and agitator 5 can be used Q235, and other part material can be used ABS, and the pen cap 1 and pen container 4 can be made with stainless steel.
