Abstract

An environment-friendly blackboard is disclosed, which belongs to a teaching aid and mainly solving the problems of low efficiency and less dust flying during erasing for traditional blackboard. The structure thereof comprises a blackboard body, wherein a slide rail used for installing an eraser and moving the eraser is disposed at the upper side of the blackboard body; the bristles of the eraser are vertical to the writing surface of the blackboard body and contacted with the writing surface; and the upper end of the eraser is slidably disposed in the slide rail via a connecting rod. The blackboard can erase the whole blackboard body once; and not only is erasing for the blackboard time-saving and labour-saving, but also harm on human body and influence on environment by the dust flying caused by erasing for the blackboard with traditional method can be avoided, and the normal use of the blackboard can be recovered in short time.

Description

A kind of environment friendly blackboard

Technical field

The utility model relates to a kind of teaching aid, specifically is a kind of environment friendly blackboard.

Background technology

Class hour on to the student is for ease of understanding and memory, for key content; Teacher can write on blackboard with chalk every now and then, and in order to prevent dust from flying, the mode that adopts wet cloth or blackboard eraser to add water is mostly wiped when erasing the board; But because the blackboard eraser volume is little; Often need wiping endlessly for a long time, could guarantee the continuation use of blackboard, so can waste time and bring very big inconvenience to student on duty or teacher.

The utility model content

The purpose of the utility model is to provide a kind of environment friendly blackboard, and what this blackboard can be time saving and energy saving fast is clean with whole blackboard disposable erasing.

The technical scheme that its technical problem of the utility model solution is taked is: a kind of environment friendly blackboard; Its structure comprises the blackboard body; Be provided with at the upside of blackboard body and be used to the slide rail blackboard eraser being installed and blackboard eraser is moved; The bristle of described blackboard eraser is perpendicular to the writing surface of blackboard body, and contacts with writing surface, and the upper end of blackboard eraser is slidingly arranged in the slide rail through connecting rod.

The beneficial effect of the utility model is: before the use; Blackboard eraser moved to does not influence the position of on the blackboard body, normally writing; When needs erase the board, hold blackboard eraser, along the direction of slide rail from blackboard one side shifting to opposite side; Because the blackboard eraser bristle directly contacts with the writing surface of blackboard body, just can be disposable that whole blackboard eraser is intact; Time saving and energy saving when not only erasing the board, and the dust from flying that can avoid conventional method to erase the board causing is to the harm of human body with to the influence of environment, and the short time is recovered the normal use of blackboard.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: 1 blackboard body, 2 blackboard erasers, 3 slide rails, 4 connecting rods.

The specific embodiment

As shown in Figure 1.A kind of environment friendly blackboard; Its structure comprises blackboard body 1, is provided with at the upside of blackboard body 1 to be used to the slide rail 3 blackboard eraser 2 being installed and blackboard eraser 2 is moved, and the bristle of described blackboard eraser 2 is perpendicular to the writing surface of blackboard body 1; And contact with writing surface, the width one of the length of blackboard eraser 2 and blackboard body 1 to; The upper end of blackboard eraser 2 is slidingly arranged in the slide rail 3 through connecting rod 4.

Before the use; Blackboard eraser 2 moved to does not influence the position of on blackboard body 1, normally writing; When needs erase the board, hold blackboard eraser 2, along the direction of slide rail 3 from blackboard body 1 one side shiftings to opposite side; Because blackboard eraser 2 bristles directly contact with the writing surface of blackboard body 1, just can be disposable that whole blackboard eraser is intact; The utility model is time saving and energy saving when not only erasing the board, and the dust from flying that can avoid conventional method to erase the board causing is to the harm of human body with to the influence of environment, and the short time is recovered the normal use of blackboard.
