Abstract

The utility model discloses a teaching chalk box which comprises a box body. A box cavity of the box body is used for containing chalk. A discharging opening where the chalk inside the box cavity is taken out is formed in the upper surface of the box body. A magnet for being attracted with an iron supporting plate to fix the teaching chalk box is arranged at the bottom of the chalk box, wherein the iron supporting plate is arranged on the lower side of a blackboard and used for receiving chalk dust. Eraser bristles for wiping chalk characters on the blackboard top are arranged on one lateral side of the chalk box. An operating handle is arranged on the side wall of the other side, opposite to the eraser bristles, of the box body. By means of the scheme, the chalk box can be fixed below the blackboard, a teacher can conveniently take the chalk, then the eraser bristles are arranged on the side wall of the chalk box so that the chalk box can have the function of a blackboard eraser, and the multi-functionalization of the chalk box is achieved.

Description

A kind of chalk box for teaching

Technical field

The utility model relates to the teaching aid field, is specifically related to a kind of chalk box for teaching.

Background technology

Teaching for politics, historical these science, it contains much information, therefore, for the student, to mastery of knowledge, teacher often first submits a written statement to a higher authority knowledge to write at blackboard and is prepared lessons, because knowledge quantity is large, often whole blackboard surface need to be write full, and the length of chalk is certain, so teacher also needs to turn around on lectern and takes other complete chalks and prepared lessons after piece of chalk uses, and causes all inconvenience and time waste.

The utility model content

The purpose of this utility model is to provide a kind of chalk box for teaching, and it can effectively address the above problem, and chalk holder can effectively be fixed on supporting plate, taking chalk while being convenient to prepare lesson.

For achieving the above object, the utility model has adopted following technical scheme: a kind of chalk box for teaching, it is characterized in that: comprise a box body, the box chamber of box body is for holding the placement chalk, on the upper surface of box body, offer for taking out the discharging opening of chalk in the box chamber, the bottom of described chalk holder is provided with for the irony supporting plate for accepting chalk dust with the setting of blackboard downside adsorbs the magnet that chalk holder is fixed mutually, one side of chalk holder is provided for the snag of the letter written with chalk on blackboard wiping plate face, the opposite side sidewall setting operation handle of the box body relative with snag.

Further scheme is: the height of described box body is 8～10cm, and the length of box body is 18～20cm, and width is 12～15cm.

Described box body comprises outside framework and forms with outside framework the grooved part that drawer-like coordinates, also be provided with draw-in groove on the trench bottom of grooved part, draw-in groove forms slide-and-guide with the raised line arranged on chassis base and coordinates, the grooved part is positioned on the cell wall outer surface of framework outside and is provided with little handle, is provided with the retaining mechanism that the residing state of grooved part is carried out to temporary card tightening position on framework.

The length of described chalk is 10～12cm, and chalk is placed along the width of box body, and the outer surface of chalk is that the waterproof colloid layer forms.

In such scheme, be provided with for the irony supporting plate for accepting chalk dust with the setting of blackboard downside and adsorb mutually the magnet that chalk holder is fixed by the bottom forming chalk holder, one side of chalk holder is provided for the snag of the letter written with chalk on blackboard wiping plate face, so just chalk holder can be fixed on to the below of blackboard, be convenient to teacher's taking chalk, secondly on the sidewall of chalk holder, snag is set, can makes chalk holder there is the function of blackboard eraser, realize the multifunction of chalk holder.
