Description

Combined blackboard

One, technical field

The utility model relates to a kind of stationery, especially relates to a kind of blackboard that water shows letter stencil and cardboard combination of meeting, and is that chance water shows letter stencil, the papery picture is write plate and formed.

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, a kind of plate of the replacement blackboard that do not produce dust of writing.

The technical scheme that the utility model technical solution problem is adopted: make a flat board (1) with running into the material that clear water promptly shows ink marks, these dull and stereotyped long 3.2 meters, wide 1 meter, thickness 0.1-2 centimetre, drawing on the periphery of dull and stereotyped (1) has centimetre to be the rule (2) of unit, and going up to draw in dull and stereotyped (1) has horizontal line, ordinate bar (4) (or having only ledgement (3)). and the appropriate location in dull and stereotyped (1) is provided with magnetic (6), bar (7) is hung in rotating shaft (5).The flat board that has (1), a single face uses, the two-sided use of the energy that has, the flat board that has sticks on the plate face of other material.

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), and ordinate (4) stroke has with centimetre rule as least unit on its four peripheries.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, and 1 limit dress is with magnetic (6) in addition.

The form of combination has following four kinds: the 1st kind is that base plate is bonded on other plate or on the wall, length is 3.2 meters to meet the apparent letter stencil (1) of water, 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, the rotating shaft of this plate (8) (5) is installed in meets water and show letter stencil) central part, the another side end with magnetic (6) picture write plate (8) be adsorbed in meet water and show letter stencil) on.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 to dull and stereotyped (1) with magnetic (6) and writes on the plate (8).The 3rd kind of combination is to get that picture is write plate (8), meeting water, to show letter stencil all be 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 (1), 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 the apparent letter stencil of chance water is this novel product schematic diagram that base plate makes up.

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.

1 is dull and stereotyped among the figure, the 2nd, and rule, the 3rd, horizontal line, the 4th, ordinate, the 5th, rotating shaft, the 6th, magnetic, the 7th, hang bar, the 8th, papery is drawn and 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 structurely, cheap, easy to use, there is not environmental pollution, will be one of ideal object of replacing by school's blackboard.
