Abstract

The utility model discloses a blackboard composed of word appearing board when meeting water and paper board. The assemble blackboard is composed of a laundry paper board and a word appearing board when meeting water. The laundry paper board has high density because it is formed with high pressing on the wood pulp served as the principal raw material matching with the glue, and the suboptical lacquer is overlaid on the surface of the laundry paper board without strong reflected light. After writing with a carbon rod pencil on the utility model, the writing can be erased with an eraser, and thus the utility model can be repeatedly used. The word appearing board when meeting water is a flat plate made of apparent material, and one hundred of left and right small holes is arranged in per square centimeter area of the flat plate, and the small holes are full filled with material that can display the ink when encountering the clear water. When written and drawn with water on the word appearing board when meeting water, a character and a picture can be seen, and the character and the picture can disappear when water is dry. The blackboard has assemble features that firstly, 1/2 area of the paper board is arranged on center of the word appearing board when meeting water via an axle; secondly, 1/2 area of the word appearing board when meeting water is arranged on the center of the paper board; thirdly, the blackboard is composed of 1/2 word appearing board when meeting water and 1/2 paper board; fourthly, the back face of the word appearing board when meeting water and the back face of the paper board are adhered into a blackboard.

Description

Meet the blackboard of existing letter stencil of water and cardboard combination

One, technical field

The utility model relates to a kind of stationery, especially relates to the blackboard of existing letter stencil of a kind of chance water and cardboard combination

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 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, on the plate face of dull and stereotyped (1), be provided with rotating shaft (5) in case of necessity, magnetic (6) is hung bar (7).(more than be to meet the existing letter stencil of water)

With the wood pulp is that primary raw material is equipped with glue, high pressure in addition, make highdensity white board (8), coat the inferior light varnish that can not produce strong reflection light on the surface of white board, the thickness of white board (8) is 0.1-2 centimetre, length is 1.5-3.2 rice, wide 1 meter, drawing on the plate face of dull and stereotyped (8) has horizontal line (3), ordinate (4), drawing on the four edges has centimetre to be the rule (2) of unit, is provided with rotating shaft (5), magnetic (6) or hangs bar (7) at 1 suitable limit end.

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

Four, description of drawings

Fig. 1 is that the existing letter stencil of chance water is this novel product schematic diagram that base plate makes up.

Fig. 2 is to be this novel product schematic diagram that base plate makes up with the white board.

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, white board.

Five, the specific embodiment

First such as shown in Figure 1, 2, that the utility model adopts embodiment: dull and stereotyped (1), white board all is provided with rule on (8), 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 the white board (8) with the carbon-point stroke, treat that not the time spent wipes the writing on the white board again, 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 of the utility model employing is: on dull and stereotyped (1) and white board (8) 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 the white board (8) with the carbon-point stroke, again writing is wiped later by the time, also can be repeatedly used it.
