Description

Magnetic force recording board

A kind of magnetic force data board belongs to cultural goods instrument class, is widely used in teaching, office field.

The blackboard of present teaching usefulness or the data board of office; be traditional chalk Writing plate mostly; chalk dust had not only hindered health but also contaminated environment; the disclosed CN2077377U of Chinese patent arbitrarily wiped word magnetic force board in the past; form by the natural magnetic patch that disappear word magnetic patch and the plate core upper surface at plate core, the plate core back side drives in the magnetic force containment vessel that the word magnetic patch that disappears moves; the complex structure though energy is arbitrarily erasable, function singleness.

It is a kind of simple in structure that the purpose of this utility model is to provide, and light practicality had both solved the dust pollution that traditional chalk is write, and can free stickyly paste again, shows literary composition table announcement etc. onboard.

The utility model is to realize like this, it is made up of magnetic force data board, Magnetic eraser and A.O., the magnetic force data board has four-layer structure, the top layer is the pure white thick china of hard, and the second layer is the metal clip laminate, and the 3rd layer is the filling plate, the back side is liner plate, four layers are bonded as one, are surrounded by aluminum alloy frame all around, enclose solid with rivet and plastics angle; Magnetic eraser is bonded by plastic foamboard shell and polypropylene fibre felt, the sticking magnetic spare that studs with of recess on the plastic foamboard shell; A.O. is with the plastic casing that is processed into different shape, and interior sticking edge magnetic spare is formed.

The utility model is simple in structure, easy to use, can be arbitrarily erasable, can announce with A.O. fixing literary composition table on the magnetic force data board again etc., can make all size, for teaching and different occasions provide cleaning, convenience, practical office accommodation, such as: blackboard, note board, work attendance plate, price plate, children to learn to read plate, calculation demonstrator etc.

Be described in detail embodiment of the present utility model in conjunction with the accompanying drawings.

Magnetic force data board (Fig. 1), by thick china 1, metal clip laminate 2, filling plate 3, liner plate 4, be bonded into one, inlay with aluminum alloy frame 5 all around, four jiaos are enclosed solid with rivet and plastics angle 6, thick china 1 can adopt the pure white thick china of hard, sandwich plate 2 can also can be used non-metal board coated magnetic with metallic plate, and filling plate 3 adopts cardboard, and liner plate 4 can adopt glued board or other fiberboard; Magnetic eraser (Fig. 3) is bonding by plastic foamboard shell 7 and polypropylene fibre felt 8, the sticking magnetic spare 9 that studs with of recess on the plastic foamboard shell 7; A.O. (Fig. 4), can be processed into the plastic casing 10 of different shape, sticking edge magnetic spare 11 in it, the hard thick china 1 of magnetic force data board Fig. 1 can be write repeatedly thereon with marking pen, Magnetic eraser (Fig. 3), can clean the various writings of writing at any time, can reach its service life more than 15 years, A.O. (Fig. 4) can be with various paper proclamations, chart, the isobaric suction of notice on magnetic force data board face.

Claims (3)

1, a kind of magnetic force data board, comprise Magnetic eraser and A.O., it is characterized in that the magnetic force data board is that non-metal board 2, filling plate 3, liner plate 4 by the pure white thick china 1 of hard, metal clip laminate or coated magnetic is bonded into one, be surrounded by aluminum alloy frame 5 all around, enclose with rivet and plastics angle 6 solid.
