CN2400284Y - Ink-feeding controller for pollutionless teaching writing pen - Google Patents

Abstract

The utility model relates to an ink-feeding controller for a novel non-pollution teaching writing pen. The utility model replaces the prior art of adopting a spring and a thimble mechanism, and is characterized in that the ink-feeding controller is divided into two sheets; one sheet near a pen head forms a bow shape, and the other sheet forms a flat sheet; the two sheets are respectively provided with three or four miniature holes. When writing is carried out, the pen head props and presses the bow-shaped ink-feeding sheets, making the two sheets tightly against each other, and ink flows to the pen head through the miniature holes. When the writing is stopped, the pen head does not prop and press the bow-shaped ink-feeding sheets, the miniature holes are separated from each other, and capillary action is stopped. The utility model has the advantages of simplicity, easy fabrication and assembly, low cost and flexible rotation.

Description

Novel environment friendly teaching writing pen control liquid cuts down the sheet device

Environmental protection teaching writing pen control liquid cuts down the sheet device and belongs to printing, articles for writing class.

Existing didactic works is write pen, adopt chalks more or compress written white or pastel with spring, because it is very complicated to control the spring pen header structure of liquid, movable part requires tightly accurate, make the loaded down with trivial details and production cost of assembling thereby increased, make also that simultaneously the useful space of pen diminishes.

The utility model adopts a kind of volume very little in order to overcome above-mentioned deficiency, and two sheets that cut down that micro-hole is arranged simple in structure have replaced parts such as spring, thimble, the mechanism that has realized simple and easy control ink.

The utility model is finished like this: between pen point casing (2) and pen container (6), what be provided with 3 horizontally-arranged micropores (9) cuts down sheet (5), ink and nib (1) are separated (seeing accompanying drawing 3), simultaneously, cut down sheet (4) what cut down sheet (5) by written side stack a slice 4 symmetrical micropores of band (8), sheet cut down (4) at ordinary times section be arc state, and its external diameter is 9/10 in cutting down sheet (5), cutting down sheet (4) is elastomeric material, when being subjected to nib (1) roof pressure, can flatten and with to cut down sheet (5) close, be adjacent to, at this moment, ink (7) will flow to nib (1) by micropore (8) (seeing accompanying drawing 2) capillarity, and be stored in the sponge volume (2), can write.At ordinary times, cut down sheet (4) and be in arc state, two micropores that cut down sheet do not keep clear of and can produce capillarity, and ink keeps not flow regime, also just can not flow on the nib.

Now be illustrated in conjunction with Figure of description: accompanying drawing 1 is the installation diagram of novel environment friendly teaching writing pen.

Accompanying drawing 2 is arc top view and vertical cross sections that cut down sheet (4).

Accompanying drawing 3 is flat top view and vertical cross sections that cut down sheet (5).Center bore is 2-3 times of other two apertures.

Embodiment: flat shape is cut down sheet (5) and is adopted 1 millimeter plastic sheet to make, and center bore is 1.5 millimeters, and in the centre bore both sides, parallel to process two apertures be 0.5 millimeter symmetrical aperture.The arc sheet (4) that cuts down also adopts the stainless steel substrates of 0.05-0.07 millimeter or copper sheet to make, and with the center symmetry, arranges little shape hole of 4 0.5 millimeter.The arc Wai Yuan that cuts down sheet (4) cuts down sheet (5) and is close to flat, and the arc center of cutting down sheet is with flat to cut down the sheet distance be 2 millimeters.

Environmental protection teaching writing pen control liquid of the present utility model cuts down the sheet device, owing to replaced labyrinths such as existing spring, thimble with two very thin sheets that cut down for a short time, therefore, make finished parts simply easy, assemble up also very conveniently, require so strictly unlike spring, thereby manufacturing cost descends, when reducing the assembler and workload, make that also the ink capacity of pen is some more relatively.

Claims (4)

1, novel environment friendly teaching writing pen control liquid cuts down the sheet device, by nib, pen point casing, pen container and be arranged on pen point casing and pen container between two cut down sheet and form, it is characterized in that: the sheet that cuts down near nib is arc to written direction, and the flat sheet that cuts down of another stack is cut down sheet and nib separates by arc.

2, the novel environment friendly teaching writing pen control liquid according to claim 1 cuts down the sheet device, it is characterized in that: the arc sheet that cuts down is provided with four symmetrical micropores, and the arc sheet that cuts down can be flattened by written roof pressure.

3, the novel environment friendly teaching writing pen control liquid according to claim 1 cuts down the sheet device, it is characterized in that: flat cutting down is disposed radially three little shape holes on the sheet, wherein the aperture of centre bore be the aperture, both sides 2-3 doubly, the aperture of centre bore is the 0.5-3.0 millimeter, and the aperture of two side holes is the 0.2-1.2 millimeter.

4, the novel environment friendly teaching writing pen control liquid according to claim 1 cuts down the sheet device, it is characterized in that: arc the arching of centre-to-centre spacing plain film of cutting down sheet highly is the 1.0-3.0 millimeter.
