Description

The chalk carrying case is used in teaching

Technical field

The utility model relates to teaching appurtenance technical field, and the chalk carrying case is used in specifically a kind of teaching.

Background technology

Chalk be in the teaching through article commonly used, at present, the used chalk of imparting knowledge to students mostly is placed in the chalk holder or wooden etui that paper does; Need in its box, extract during use; Because a large amount of chalks is crowded together, extract very inconvenience, this has brought a lot of troubles for the teacher of teaching.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, and the chalk carrying case is used in the teaching of being convenient to the chalk extraction.

The purpose of the utility model is achieved in that this teaching is made up of box body, lid, dividing plate, push pedal, pumping rod, sleeve pipe, support bar, limiting plate with the chalk carrying case; The bottom surface outer wall is provided with in the slot on the cuboid box body upper end front and rear panel face inwall of sucker the slip suit and lid; The dividing plate of box body inside is identical with chalk length apart from the distance of slot; The pumping rod that the outer end is provided with finger ring links to each other with the movable push of dividing plate top after passing the through hole on the box portion right lateral plates, is with support spring I on the pumping rod between push pedal and the box portion right lateral plates; The interior slip suit of square casing fixing above the outer wall of box body left side the support bar that the upper end that adapts with it is provided with stripper plate; Be with support spring II on the support bar of sleeve pipe top; The limiting plate of support bar lower end vertical fixing gets into box body after passing the rectangular through holes on the box portion left lateral plates below the dividing plate, and vertical fixing the push rod that adapts with circular hole above the dividing plate left end on the limiting plate in the box body.

Behind the pulling pumping rod chalk laterally vertically is placed on the dividing plate in the box body successively; It is stable with the chalk clamping under the effect of support spring I, to promote push pedal; Through sucker this device is absorbed and fixed on the lectern then; Push the stripper plate of post upper and make push rod break away from above the dividing plate left end loosening again support bar behind the circular hole, the push rod above the limiting plate can will eject near the chalk of the box body leftmost side, takes out that the chalk in the box body moves to left under the effect of push pedal and support spring I successively behind the chalk.

The advantage of the utility model: simple in structure, easy and simple to handle, can very easily the chalk in the box body be taken out, time saving and energy saving, improve efficiency of teaching.
