Description

Meet the blackboard of the apparent letter stencil of water, cardboard combination

One, technical field

The utility model relates to a kind of stationery, especially relates to a kind of blackboard that water shows letter stencil, cardboard combination of meeting.

Two, background technology

The blackboard that uses in the school writes thereon with chalk now, produces the dust that flies upward in a large number during the wiping letter written with chalk, and contaminated environment is serious.

Three, Fa Ming content

In order to overcome the write with chalk serious environmental pollution of word of blackboard, the purpose of this utility model provides a kind of easy to use, and is cheap, writes not produce the combined blackboard of dust.

The technical scheme that the utility model technical solution problem adopts has following 4 points: the first, make a flat board (1) with the transparent material that does not absorb water, slab-thickness 0.1-2 centimetre, long is 0.5-3.2 rice, and wide is 0.2-1 rice.The second, many apertures (2) of take-through plate face are set on plate (1), the distance between aperture and the aperture is the 1-0.5 millimeter, the diameter of aperture is the 1-0.5 millimeter.Three, fill up with running into the material that water can show ink marks in the aperture (2), make the plate face smooth, the material water imbibition in this aperture is medium, can not go mouldy because of high humidity.The 4th, drawing on the flat board has horizontal line (3), ordinate (4), and rule, rotating shaft (5), magnetic (6) is hung bar (7).The flat board that has (1), a single face uses, the two-sided use of the energy that has.

Papery is drawn and to be write plate (8), and scribbling glue on the cardboard, color is a black, deep blue, dark green etc., and drawing it on has horizontal line (3), ordinate (4), stroke have on its four peripheries with centimetre as, the rule of subsection.Papery is drawn the length of writing plate: 0.5-3.2 rice, wide 0.3-1 rice; Thickness is 0.1-1 centimetre, writes 1 limit fit on rotating shaft (5) of plate (8) at picture, in addition 1 limit assembling magnetic (6).

The form of combination has following four kinds: the 1st kind, to show letter stencil (1) be base plate to meet water, is bonded on other plate or on the wall, length is 3.2 meters, wide 1 meter, 0.1 centimetre of thickness; Getting picture, to write plate (8) be 1.5 meters long, wide 1 meter, thick 0.4-2 centimetre, and the rotating shaft of this plate (8) (5) is installed in meets the central part that water shows letter stencil (1), the another side end is write plate (8) to picture with magnetic (6) and is adsorbed in and meets water and show on the letter stencil (1).The 2nd kind of combination, writing plate (8) with picture is base plate, is pasted on other plate or on the wall, length is 3.2 meters, wide 1 meter, thickness 0.1-0.4 centimetre; Getting and meeting the apparent letter stencil of water is 1.5 meters long, wide 1 meter, thick 0.4-2 centimetre, the rotating shaft of this plate (1) (5) is installed in the central part that picture is write plate (8), and the another side end is adsorbed in picture with magnetic (6) with flat board (1) and writes on the plate (8).The 3rd kind of combination is to get picture to write plate (8), and meeting the apparent letter stencil (1) of water all is long 1.6 meters, and wide 1 meter, thick 0.2 centimetre, amalgamation is grown into 3.2 meters, and wide 1 meter rectangle is bonded on other plate face or on the wall.The 4th kind of combination is that picture is write plate (8), meets water and shows letter stencil, is bonded into same plate, and then this plate face is that picture is write plate (8), and another face is to meet water to show letter stencil (1).

Four, description of drawings

Fig. 1 is that to show letter stencil be this novel product schematic diagram that base plate makes up to meet water.

Fig. 2 is that to write plate with picture be this novel product schematic diagram that base plate makes up.

Fig. 3, the 4th is with this novel product schematic diagram of two plate amalgamations.

Among the figure, the 1st, dull and stereotyped, the 2nd, can show the aperture that the material of ink marks fills up to meet water, the 3rd, horizontal line, the 4th, ordinate, the 5th, rotating shaft, the 6th, magnetic, the 7th, hang bar, the 8th, picture is write plate.

Five, the specific embodiment

First such as shown in Figure 1, 2, that the utility model adopts embodiment: dull and stereotyped (1), picture is write on the plate (8) and all is provided with rule, horizontal line, ordinate, rotating shaft, magnetic etc.On dull and stereotyped (1), write picture with clear water pen (or with writing brush libation at an ancient wedding ceremony water).If will make writing keep the longer time, then be written on picture and write on the plate (8) with the oilstone stroke, treat that the writing that time spent not writes picture on the plate again wipes, to wait to reuse, this plate also can reuse for ten million time.In case of necessity, magnetic (6) can be drawn back, make plate (8) (or plate (1)), enable another side along rotating shaft (5) upset.

As shown in Figure 3, second embodiment adopting of the utility model is: write on the plate (8) at dull and stereotyped (1) and picture rule, horizontal line, ordinate are set.Write on dull and stereotyped (1) with the clear water pen, the clear water place of arrival promptly shows ink marks, and the dried word of water disappears, and can be repeatedly used; If it is long-time that writing is kept, then be written on picture and write on the plate (8) with the oilstone stroke, again writing is wiped later by the time, also can be repeatedly used it.

The 3rd embodiment that the utility model adopts is: the bonding this flat board of plate (8) is write in dull and stereotyped (1) and picture, both sides or the right and left are provided with the extension bar up and down, this plate can move separately and take away, hang up and carry out picture in necessity place and write, writing will keep the longer time, writes on picture and writes on the plate (8), and writing need not keep for a long time, be written on the flat board (1), the dried word of water disappears.This plate that is bonded, its two sides all can repeatedly be used repeatedly.

Owing to adopted above technology, the utlity model has simple in structure cheaply, easy to use, there is not environmental pollution, will be one of ideal object of replacing by school's blackboard.
