Description

Multifunctional blackboard eraser

Technical field

the utility model relates to the blackboard eraser technical field, is a kind of multifunctional blackboard eraser.

Background technology

in teaching process, existing blackboard eraser produces chalk dust in the process erased the board, chalk dust is after being adsorbed by human body, can cause inflammation to respiratory system, skin, ear, nose, the throat of human body, thereby the healthy of human body worked the mischief, in addition, existing blackboard eraser is placed on lectern after wiping blackboard, increases the workload of teacher in teaching process.

Summary of the invention

the utility model provides a kind of multifunctional blackboard eraser, has overcome the deficiency of above-mentioned prior art, and its chalk dust that can effectively solve the generation that existing blackboard eraser exists in actual use is detrimental to health and increases the problem of teacher workload.

the technical solution of the utility model realizes by following measures: a kind of multifunctional blackboard eraser, comprise box body, bottom outside at box body is fixed with rub body, be installed with magnetic patch on the box body of at least one side of rub body, be distributed with the apopore corresponding with rub body in the bottom of box body, be installed with the first riser that spacing is arranged with the box body bottom at the middle part of box body, be fixed with level board between the first riser and box body right-hand member, form reservoir chamber in the box body of the first riser left and level board below, form the chalk chamber in the box body of level board top, upper end in reservoir chamber and chalk chamber all is installed with lid.

below the further optimization and/or improvements to above-mentioned utility model technical scheme:

be fixed with the second riser on the right-hand level board of above-mentioned the first riser, form holding chamber between the first riser and the second riser, upper end at holding chamber is fixed with lid, be provided with the putting hole that is no less than on lid, be placed with the picture round belting in putting hole, draw round belting and comprise work circle chalk and flexible strand, in the upper end of putting hole, be fixed with retainer ring, one end of flexible strand is fixed together with making the circle chalk, and the other end of flexible strand is fixed on retainer ring.

can be provided with the water filling port that is no less than on lid on above-mentioned reservoir chamber.

above-mentioned rub body can be sponge rub body or cloth rub body.

the utility model reasonable and compact in structure, easy to use, the setting of reservoir chamber can soak rub body, and wetting rub body, in the process erased the board, reduces the generation of chalk dust, thereby has reduced the harm of chalk dust to health; The setting of magnetic patch, make blackboard eraser can be adsorbed on the optional position of blackboard, reduced teacher's workload.

The accompanying drawing explanation

the main TV structure schematic diagram that accompanying drawing 1 is the utility model most preferred embodiment.

the plan structure schematic diagram that accompanying drawing 2 is the utility model most preferred embodiment.

coding in accompanying drawing is respectively: 1 is box body, and 2 is the chalk chamber, and 3 is holding chamber, and 4 is reservoir chamber, and 5 is the first riser, 6 is the second riser, and 7 is magnetic patch, and 8 is rub body, and 9 for making the circle chalk, and 10 is flexible strand, 11 is retainer ring, and 12 is lid, and 13 is water filling port, and 14 is apopore, and 15 is level board.

The specific embodiment

the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

in the utility model, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.

below in conjunction with embodiment and accompanying drawing, the utility model is further described:

as accompanying drawing 1, shown in 2, this multifunctional blackboard eraser comprises box body 1, bottom outside at box body 1 is fixed with rub body 8, be installed with magnetic patch 7 on the box body 1 of at least one side of rub body 8, be distributed with the apopore corresponding with rub body 8 14 in the bottom of box body 1, be installed with the first riser 5 that spacing is arranged with box body 1 bottom at the middle part of box body 1, be fixed with level board 15 between the first riser 5 and box body 1 right-hand member, the interior formation reservoir chamber 4 of box body 1 in the first riser 5 lefts and level board 15 lower ends, the interior formation chalk of box body 1 chamber 2 at level board 15 upper ends and the first riser, the interior formation reservoir chamber 4 of box body 1 of the first riser 5 lefts and level board 15 belows, the interior formation chalk of box body 1 chamber 2 of level board 15 tops, upper end in reservoir chamber 4 and chalk chamber 2 all is installed with lid 12.The setting of chalk chamber 2 can be held chalk; Thereby the setting of magnetic patch 7 can make the utility model be close on blackboard prevents that the utility model from coming off from blackboard, and the teacher, without blackboard eraser is placed on dais, has reduced teacher's workload; Water is injected to reservoir chamber 4, and the water in reservoir chamber 4, by the wetting rub body 8 of apopore 14, makes rub body 8 in the process erased the board, and reduces the healthy harm of chalk dust to teacher or student.
