The multifunctional plastic chalk box can be used for placing chalks and chalk heads, can also be used for placing stationeries such as erasers and pens, and has the advantages of reasonable design and simple structure; the multifunctional plastic chalk box can be formed easily by a mold; the multifunctional plastic chalk box is energy-saving, environmentally friendly, economical and applicable; and placement and searching of training aids for teachers are facilitated.
Description
Technical field
The present invention relates to a kind of teaching aid---chalk holder, specifically a kind of have deposit chalk, pen and blackboard eraser function in one multifunctional plastic chalk holder.
Background technology
Chalk, blackboard eraser and pen are the requisite realias of school.The chalk holder that school uses, be generally the disposable paper-made packing box of chalk manufacturer packaging chalk, in use, paper package cracky, causes chalk to tumble everywhere to teachers and students.Teacher does not have fixture to deposit with surplus chalk end, and on the lower edge being placed on blackboard or dais, chalk end also can tumble on the ground.Like this, not only uneconomical but also contaminated environment.The blackboard eraser being stained with chalk powder is at will deposited, not only unhygienic but also be inconvenient to find.The stationery such as pen, the pencil bulk storage that teacher uses is on dais, not only messy but also be inconvenient to use.At present, market there is no economy, be suitable for, be easy to the device of production, hold the stationery such as chalk, chalk end, blackboard eraser and pen.
Summary of the invention
The object of the invention is: provide a kind of structure simple multifunctional plastic chalk holder, it can deposit chalk, chalk end, can deposit the stationery such as blackboard eraser and pen again, be convenient to teacher and place and find teaching aid.
The technical solution adopted in the present invention is: chalk holder is a kind of box of integral type, chalk holder profile is bottom surface is that rectangle is with the stereochemical structure of round-corner transition, three parts after in before being divided into, center is higher than peripheral portion, and the height of surrounding is equivalent to the length of chalk.Rear side is the blackboard eraser groove of approximate cuboid; The center pen container that to be cross section be " heart " at middle part is higher than remainder; The both sides of pen container are cross section is respectively the white chalk groove of a sideband arc approximate trapezoid and color ledge for chalk on blackboard; The chalk end groove of a sideband arc approximate trapezoid that to be cross section be in chalk holder front portion.
The invention has the beneficial effects as follows: diverse in function that there is the function of placing the stationery such as white chalk, color chalk, chalk end, blackboard eraser and pen; Reasonable in design, structure is simple, is easy to mould molding; Economical environment-protective, economic and practical, convenient teaching.
