Abstract

The utility model relates to a writing board cleaning device improving technical field, providing a dust-free large-scale teaching board and a teaching pen, which is composed of a teaching board and a teaching pen. The teaching board comprises a magnetic mainboard, plate and frame, a blackboard eraser and a drawing groove. A magnetic pen point on the teaching pen is utilized for writing or drawing on the magnetic mainboard, and a magnetic stripe on the blackboard eraser is draught to erase characters and patterns on the mainboard, thereby achieving convenient writing or erasing, time saving, labor saving, non-dust, non-pollution, healthy utilization, economy, lower cost and convenient spread.

Description

Large-scale board of education of no dust and teaching pen

Technical field

The utility model belongs to printing articles for writing class, relates to clipboard cleaning device technological improvement technical field.

Background technology

Existing blackboard for education and chalk use inconvenient, unhygienic.Its reason is that existing blackboard for education constitutes by coat atrament on certain plane (as cement or wood-block plane).When on blackboard, writing, unavoidably can produce dust with the teaching chalk; When wiping written contents with blackboard eraser, dust fills the air especially.This health to the instructor directly causes damage.In addition, it is also inconvenient to erase the board with existing blackboard eraser, wastes time and energy.

Existing toy book drawing board and writing-painting provide the bench model that replaces existing blackboard for education and chalk.This painting and calligraphy board is made up of mainboard, blackboard eraser and sheet frame three parts.Mainboard is the double-decker of being made by a kind of magnetisable material, be a kind of mixture that injects magnetic and corrosion-resistant liquid material in the middle of it, and this mixture is cut apart by the alveolate texture thing.Blackboard eraser mainly is a magnetic stripe, and it is embedded in the blackboard eraser groove, is limited to the mainboard reverse side by sheet frame pulling groove and blackboard eraser button, can about pulling.Behind the written contents of front, can wipe positive content by the pulling blackboard eraser.Sheet frame works to limit blackboard eraser and fixed head face and attractive in appearance.Attached writing-painting is made up of a body and nib.Body is made of plastics, and nib is made by magnet.

Summary of the invention

The utility model technical issues that need to address are for overcoming the big defective of above-mentioned conventional blackboard dust and by the successful technology of toy book drawing board, providing large-scale board of education of a kind of no dust and teaching pen.It is made up of board of education and teaching pen two parts.Its board of education is made up of magnetic mainboard, sheet frame, blackboard eraser and pulling groove, and the magnetic mainboard is fixed in the middle of the sheet frame, and the pulling groove places the sheet frame bottom, and blackboard eraser places magnetic mainboard reverse side, and its underpart is embedded in the pulling groove.Teaching pen is made up of with two magnetic writerheads that are contained in the penholder two ends penholder.The magnetic mainboard is made by a kind of magnetisable material and is with cellular inside and outside clamping plate, inject the mixture that contains magnetic and anticorrosion liquid material between the clamping plate, and this mixture quilt is cut apart with the alveolate texture on the inside and outside clamping plate.Blackboard eraser has more than two, the rarest two, and all place the back side of magnetic mainboard, lower end to be embedded in the pulling groove, blackboard eraser can about pulling, and each blackboard eraser by a magnetic stripe and fixedly the bar of magnetic stripe formed, the bar of blackboard eraser lower end is embedded in the groove that spurs groove.When writing with the two ends random magnetism nib of teaching pen or painting on the outside plate of magnetic mainboard; magnetisable material such as magnetic that magnetic on the magnetic writerhead will be clipped between the magnetic mainboard attract to invest on the outside plate of magnetic mainboard; because the clamping plate of magnetic mainboard are magnetisable material; so on the outside plate of magnetic mainboard, the magnetic of absorption forms certain writing or pattern.If will eliminate writing or pattern on (wiping) magnetic mainboard outside plate; with pulling about the bar of blackboard eraser bottom is in the pulling groove; magnetic stripe on the blackboard eraser is move left and right also; because magnetic lineation magnetic is adsorbed onto the magnetic that forms writing or pattern on the magnetic mainboard on the inner panel of magnetic mainboard, writing on the magnetic mainboard outside plate or pattern are eliminated.Because blackboard eraser is by forming more than two, so writing on the magnetic mainboard of erasing or pattern can carry out step by step.If only spur left side blackboard eraser, writing on the outside plate of the left side magnetic mainboard of can erasing or pattern and writing or pattern on the right magnetic mainboard outside plate of not erasing; If pulling the right blackboard eraser only, writing on the right magnetic mainboard outside plate of can erasing or pattern and writing or pattern on the left side magnetic mainboard outside plate of not erasing.If adopt a plurality of blackboard erasers, corresponding writing or pattern on the magnetic mainboard outside plate of then can repeatedly erasing step by step can be used the written handwriting or the pattern of teaching pen then more again on the magnetic mainboard outside plate of part of erasing.The utility model does not have the magnetic of large-scale board of education of dust and teaching pen can dye shades of colour, thus the various respective color of writing and pattern displaying, appearance looks elegant.

The advantage that the utility model does not have large-scale board of education of dust and teaching pen is: 1, use magnetic teaching pen without chalk, no dust pollution uses health, and can use repeatedly, has saved resource.2, erasing writing or pattern only need the bar in the pulling blackboard eraser lower end pulling groove without the brush plate, can erase rapidly and wait to smear the writing and the pattern of part.Easy to use, time saving and energy saving.3, potential market is big, and units such as family and kindergarten, primary school, middle school, university can use.If 4 install and use on family's metope, can convenient for children at the random painting and calligraphy in bigger space, avoid destroying metope; In addition, adult's account is also very convenient.5, the utility model cost of manufacture is not high, can not make a difference to purchasing power, is worth of widely use.
