Abstract

The utility model discloses a blackboard which is convenient for hanging charts and makes writing orderly and goodly. The inside or the back side of various blackboards of which bottom boards made of non-steel materials is provided with iron sheets or magnetic blocks, and the iron sheets or the magnetic blocks are fixed by the methods of mosaic, adhesive joint or riveting, etc. The surface of a blackboard is marked with the positions of the iron sheets or the magnetic blocks by a hanging chart mark, the marking color is different but similar to that of the surface of the blackboard, and the marking lines can be broken lines, or real lines or dot lines. The surface of the blackboard of which the bottom board made of various metal and non-metal materials is provided with transverse line lattices or square lattices or other various lattices. The line color of the lattices is different but similar to that of the surface of the blackboard, the lattice lines can be broken lines, or real lines or dot lines, and the lattices are hidden lattices.

Description

Blackboard

The more convenient practicality of various blackboards that the utility model uses than tradition.

At present, domestic and international all various metal blackboards and nonmetal blackboards that use, comprise wooden blackboard, Blackboard made of bamboo, Glass blackboard, plastic blackboard or the like, especially the classroom blackboard of fabric width more than 3 meters, writing draws is difficult to reach the effect of neat appearance, and except that the steel blackboard, wall chart is also very inconvenient.

The purpose of this utility model provides a kind ofly to be convenient to wall chart, to make the blackboard of writing neat appearance, and blackboard panel has horizontal line lattice, grid or other various grid, and lines are hidden line, are called for short latent lattice.

Technical solution of the present utility model is:

For solving the problem of being convenient to wall chart of making the blackboard of base plate with various non-steel materials such as wood based panel (comprising fiberboard, glued board, particieboard etc.), bamboo scutum, glass, plastics, iron plate or magnetic patch are set at the inside or the back side of blackboard.Iron plate or magnetic patch can with inlay, way such as bonding, rivet clasp fixes.Mark iron plate or the corresponding position of magnetic patch at blackboard panel with mark.The color of this wall chart mark is different with the blackboard panel color and close.Mark can be dotted line, solid line or some note.Just very convenient at blackboard surface use Magnetic drawing pin wall chart and magnetic teaching aid like this.

Write the purpose that reaches neat appearance when drawing for making on various blackboards (blackboard that comprises all various metals and nonmetallic materials making base plate) plate face, at blackboard panel, use the color different and close to mark horizontal line lattice, grid or other various grid with the blackboard panel color.The grid lines can be used dotted line, solid line or some note.These latent lattice can make that writing draws reaches the effect of neat appearance, and don't influence vision.Should note concealing lattice should distinguish to some extent with the wall chart mark.These latent lattice are applicable to that all metals and nonmetallic materials make the blackboard of base plate.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a blackboard base plate front schematic view.Blackboard surface does not claim the blackboard base plate before being coated with blackboard coating.

Fig. 2 is the left pseudosection of Fig. 1.

Fig. 3 is the blackboard panel front schematic view.The blackboard coating layer that is coated on the blackboard base plate face claims blackboard panel.

The 1. blackboard base plates of doing with fiberboard or particieboard 2. are embedded in the parallel iron plate of two row of blackboard the inside or magnetic patch 3. blackboard panels 4. wall chart marks (marking the iron plate that is embedded in the blackboard the inside or the relevant position of magnetic patch) 5. hidden line are lined among the figure

The quantity and the position of inlaying iron plate or magnetic patch in the blackboard the inside can be provided with as required.The color of wall chart mark and latent lattice should be different with the blackboard panel color and close.Wall chart mark and latent lattice also should be differentiated.

Claims

1, a kind of Blackboard with vanished checks of being convenient to wall chart is characterized in that: the inside or the back side at blackboard base plate 1 are provided with iron plate or magnetic patch 2, mark wall chart mark 4 in the relevant position of blackboard panel 3, also have latent lattice 5 on the blackboard panel.

2, the Blackboard with vanished checks of being convenient to wall chart according to claim 1, it is characterized in that iron plate or magnetic patch can with inlay, way such as bonding or rivet clasp is fixed on the blackboard the inside.

3, the Blackboard with vanished checks of being convenient to wall chart according to claim 1 is characterized in that the color of described wall chart mark is different with the blackboard panel color and close, can be dotted line, solid line or some note.

4, the Blackboard with vanished checks of being convenient to wall chart according to claim 1 is characterized in that described latent lattice can be lined, grid or other various grid.
