Abstract

The utility model discloses a close type multi-purpose automatic chalk box which belongs to the teaching stationery field and is composed of a chalk box body (1), a blackboard eraser box. The utility model is characterized in that both the chalk box body and the blackboard eraser box are fixed on the top of a chalk powder storage box (4). A teaching stick laying groove (6) is arranged in the front side of the chalk powder storage box (4). The front side of the chalk box body (1) is provided with an automatic rolling exit (7), and the chalk box body (1) is internally provided with a chalk propelling device (8). The close type multi-purpose automatic chalk box of the utility model is integrated together with chalks, a blackboard eraser and a teaching stick, thus the structure is compact, and the usage is convenient. Moreover, the chalks can automatically roll out when being used by the user, and the chalk powder can automatically drop into the chalk powder storage box in a state of sealing; thereby reducing the pollution caused by the chalk powder.

Description

The closed automatic chalk holder of using more

Technical field

The utility model relates to a kind of teaching aid, particularly a kind of closed automatic chalk holders of using more.

Background technology

Chalk holder is the common tool in the teaching, and employed chalk holder in teaching generally is to adopt square carton, chalk vertically is contained in the chalk holder, open the lid from the top when taking chalk, arrest the chalk end, extract chalk out, this chalk holder extracts very inconvenient, in chalk holder chalk not for a long time, chalk often tiltedly is placed in the chalk holder, also fractures easily, and the chalk dust in the chalk holder spills outside the box contaminated environment easily.Blackboard eraser, religion bar that teaching at present is used after using up, often are placed directly on the dais, and chalk dust pollutes dais and textbook easily, and the chalk dust that flies upward is scattered, and is also unhygienic.

Summary of the invention

The purpose of this utility model is to provide a kind of above the deficiencies in the prior art that overcome, and makes chalk take conveniently, can reduce the pollution of chalk dust and can put into blackboard eraser in an orderly manner and teach a kind of closed automatic chalk holders of using of bar more.

For reaching above purpose, the technical scheme that the utility model adopted is: these closed automatic chalk holders of using more, by the chalk holder box body, blackboard eraser is put into box and is constituted, on the chalk holder box body, be provided with loam cake, it is characterized in that chalk holder box body and blackboard eraser put into box be fixed on jointly a dust Storage Box above, on the base plate of chalk holder box body and blackboard eraser put on the base plate of box and be equipped with netted open-end hole, the chalk dust that chalk dust in the chalk holder box body and blackboard eraser are put into box can fall into the dust Storage Box by the netted open-end hole on its base plate, establish the religion bar in the front side of dust Storage Box and put into groove, establish chalk in the front side of chalk holder box body and roll out mouth automatically, in the chalk holder box body, establish the chalk ejecting device.The utility model is also implemented by following measure: establish drawer in the dust Storage Box, so that pourable at any time its dust; Described chalk holder box body is established two, laterally puts into white chalk and pastel respectively; Described chalk ejecting device, by preceding push pedal, promote spring, the derivation plate constitutes, preceding push pedal is a rectangular slab, its length is consistent with the length of chalk, its height is consistent with the degree of depth of chalk holder box body inner chamber, an end that promotes spring is fixed on the plate face of preceding push pedal, the other end is fixed on the rear wall inboard of chalk holder box body, effect by preceding push pedal, make the chalk in the chalk holder box body concentrate on the side that chalk rolls out mouth automatically, establish the derivation plate in the front side of chalk holder box plate, the derivation plate stretches out chalk and rolls out mouth automatically, deriving the inside edge of plate fixes by the edge of the base plate of flexure strip and chalk holder box body, when pressing the derivation plate, chalk can roll out in the mouth automatically from chalk along the derivation plate and roll out, when not pressing the derivation plate, derive plate and be stuck on the upper edge that chalk rolls out mouthful automatically upwards lifting under the effect of flexure strip, prevent that chalk from continuing to roll out.When using the utility model, as long as press the derivation plate, chalk can roll out automatically, and the blackboard eraser of the usefulness that erases the board can directly be put into the blackboard eraser holder, and the religion bar is flexible religion bar, puts into religion bar standing groove after the religion bar can being shortened.

The beneficial effects of the utility model are: compare with the chalk holder of present use, can collect chalk holder, pastel box, blackboard eraser placement, religion bar be positioned over one, compact conformation, easy to use, and when getting chalk, chalk can roll out automatically, chalk dust can fall in the dust Storage Box under sealing state automatically, so can reduce the pollution of chalk dust.
