Abstract
The invention relates to a teaching article, in particular to a blackboard dust collection box which is used for a blackboard in a classroom of a school. A hole, namely a bottom layer hole, is formed in the bottom at one end of a blackboard groove, namely a bottom layer of the blackboard groove; a plastic box, the dust collection box, with a top opening is placed just below the bottom layer hole for collecting chalk dust. A magnet is arranged on the two sides of the upper surface of the dust storage box respectively; iron blocks are arranged on the two sides of the bottom layer hole of the blackboard groove bottom layer respectively; because of the attraction effect of the magnets and the iron blocks, the dust collection box can be close to the bottom layer hole of the blackboard groove. At ordinary times, the chalk dust in the blackboard groove is cleaned into the dust collection box by using a blackboard brush or a towel; if the dust in the dust collection box is required to be cleaned, the dust collection box can be held by a hand and can be removed with proper force to clean the chalk dust in the dust collection box.
Description
Technical field
The present invention relates to a kind of realia, the blackboard chalk dust receiver used in especially a kind of classroom blackboard.
Background technology
The blackboard that present school generally uses, be the outwardly formation blackboard slot of blackboard lower edge, the effect of blackboard slot, one is when erasing the board with blackboard brush, and chalk dust drops in blackboard slot, thus avoids chalk dust to be scattered everywhere.Two is place blackboard newspaper brush and chalk.But when collecting chalk dust from blackboard slot, due to the projection of blackboard slot surrounding edge, and there is no special collection kit, be all generally the finger by people, make to collect chalk dust very inconvenient.
Summary of the invention
In order to overcome the problem using traditional blackboard to be inconvenient to collect chalk dust, the invention provides a kind of chalk dust receiver used in blackboard slot, just can solve the problem preferably.
The technical solution adopted for the present invention to solve the technical problems is; At bottom and the blackboard slot bottom of an end slot of blackboard slot, opening a hole and bottom mouth, immediately below bottom mouth, placing plastics box and the dust receiver of a upper opening, for collecting chalk dust.In upper surface two side of dust receiver, place a magnet respectively, be placed with iron block respectively in bottom mouth two side of blackboard slot bottom, due to the suction of magnet and iron block, make dust receiver can abut against the bottom mouth place of blackboard slot.At ordinary times, with blackboard brush or towel, the chalk dust in blackboard slot is cleared up in dust receiver, if by the dust cleaning in dust receiver, dust receiver need can be grasped, suitably firmly can remove dust receiver and remove inner chalk dust.
The invention has the beneficial effects as follows, below the blackboard slot of blackboard, lay a dust receiver, can collect easily and clear up chalk dust.
