In the blackboard eraser, a magnetic block 10 is arranged, and a bolt 9 is rotatablely connected with the internal thread of the magnetic block through the outer shell. A contact block 11 is arranged at the lower end of the magnetic block 10, and the contact block is made of flexible material. The pen point of the pen 13 is a small magnetic block 14 and the middle part of a pen holder 12 is hollow. The groove is arranged on the front end of the pen holder 12, and the pen 13 is inserted into the groove. The utility model has the advantages of writing clearly, cleaning with no dust and cleaning with little labor, the pen point of the blackboard pen is provided with the small magnetic block which can not be wasted when the blackboard is cleaned, and thus the expense can be saved.

Description

Ashless magnet board and matching used blackboard eraser and blackboard pen

Affiliated technical field

The utility model relates to a kind of writing on the blackboard blackboard, especially ashless magnet board and matching used blackboard eraser and blackboard pen.

Background technology

The blackboard that uses is to use chalk when writing at present, and dust just flies upward everywhere during with the blackboard eraser wiping, pollutes.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of ashless magnet board and matching used blackboard eraser and blackboard pen.The technical scheme that its technical problem that solves the utility model adopts is: the bottom of described ashless magnet board is conventional blackboard 1, at least three magnet boards 2 arranged in a crossed manner above, magnet board 2 lower ends place in the groove 3, the upper end is provided with roller 4, is provided with a bar magnet 15 between conventional blackboard 1 and magnet board 2.Magnet board 2 is made of side by side six posts 6, and its backboard 8 is stained with hard laminate, and header board 7 is stained with transparent panel, is marked with magnetic material in six posts 6.Described blackboard eraser is to be provided with magnetic patch 10 in blackboard eraser, and bolt 9 sees through the internal thread that shell is screwed in magnetic patch, and the lower end of magnetic patch 10 is a contact block 11, and contact block 11 is a flexible material.The blackboard pen is made up of penholder 12 and nib 13, and the nib portion of nib 13 is little magnetic patch 14, and the centre of penholder 12 is hollow, and the front end of penholder 12 is provided with groove, and nib 13 is inserted in the groove.

The beneficial effects of the utility model are, it is clear to write, and wiping does not have dust, and wiping is more laborsaving, and the nib of blackboard pen is that little magnetic patch does not have loss, have saved the expense of buying pen.The utility model is simple in structure, and is easy to operate, non-environmental-pollution.

1. conventional blackboards among the figure, 2. magnet board, 3. groove, 4. roller, 5. housing, 6. six posts, 7. header board, 8. backboard, 9. bolt, 10. magnetic patch, 11. contact blocks, 12. penholders, 13. nibs, 14. little magnetic patch, 15. bar magnets.

The specific embodiment

As Fig. 1,2, three magnet board 2 movable push-and-pulls, in the time will using conventional blackboard 1, three magnet boards 2 can be shifted onto on one side.As Fig. 2,3,4,5,6, in the time will writing on magnet board 2, the blackboard pen is picked up near the magnetic material in 2, six posts of magnet board 6, presents the calligraphy and painting that will write.When the calligraphy and painting of having write with blackboard eraser wiping part, the magnetic patch 10 in the blackboard eraser can push back the magnetic material in six posts 6 bottom, has write calligraphy and painting and has disappeared.When the calligraphy and painting of wanting wiping all to write, pulling bar magnet 15, bar magnet 15 all pushes back the bottom with the magnetic material in six posts 6, has write calligraphy and painting and has disappeared.When 10 magnetic force of the magnetic patch in the blackboard eraser are too sufficient or not enough, can be screwed to the position that bolt 9 is regulated magnetic patch, reach the magnetic force of regulating blackboard eraser.In the penholder 12 of blackboard pen is hollow, can place the nib 13 of the little magnetic patch 14 of band different-diameter, by changing the nib 13 of blackboard pen, regulates the thickness of writing.
