Abstract
The utility model relates to a chalk box, a box body is of a hollow right-angled trapezoidal structure, the top surface of the box body is provided with a strip-shaped throwing opening, and the direction of the throwing opening is parallel to the inclined plane of the trapezoid; a slant slideway is arranged in the box body, the bottom of the inclined plane of the box body is provided with a strip-shaped opening, and both ends of the slideway are respectively communicated with the throwing opening and the strip-shaped opening; the throwing opening is parallel to the strip-shaped opening; the bottom edge of the strip-shaped opening is provided with a slant baffle plate; the width of the slideway is twice smaller than the diameter of a chalk. When the chalk box is used, a user takes a chalk from the strip-shaped opening at the bottom of the box body, after the chalk is taken out, the chalks of the upper lays naturally falls under the action of the gravity to fill the gap of the strip-shaped opening again for being taken out next time. The chalk box has the advantages of reasonable structure, wide application, beautiful appearance, simple process, etc.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of chalk holder.
Background technology
As everyone knows, chalk holder is a most important chalk storage tool in the teaching at present.But present chalk holder all adopts the cube box body structure, and chalk is vertically settled side by side, when teachers and students use, must vertically extract chalk in box body, and very inconvenience is lost time.For this reason, we provide a kind of new-type chalk holder, for teachers and students provide a kind of condition that picks and places easily.
Summary of the invention
The purpose of this utility model provides a kind of chalk holder, is used to solve the take problem of chalk of common flour pencil box inconvenience.
For achieving the above object, the utility model chalk holder comprises box body, and described box body is the right-angled trapezium hollow-core construction, and end face is offered the bar shaped dispensing port, and the dispensing port direction is parallel with trapezoidal inclined-plane; Be provided with oblique slideway in box body, the box body surface bottom is offered strip gab, and the slideway two ends communicate with dispensing port, strip gab respectively; Dispensing port is parallel with strip gab; At the oblique baffle plate of place, strip gab base processing; Chute width is less than 2 times of chalk diameters.
After adopting said structure, the user puts into box body to chalk from dispensing port one by one, and chalk slides to strip gab from slideway, blocked by oblique baffle plate and stops, because chute width is less than 2 times of chalk diameters, so chalk keeps arranging in order; During use, the user takes out chalk from the bottom strip gab and uses, and after taking out chalk, the upper strata chalk is fallen by gravity effect naturally, fills up the breach of strip gab again, is convenient to take next time.
The utility model has the advantages that: rational in infrastructure, be widely used, good looking appearance, technology be simple, can take out chalk, convenient and efficient fast.
