Abstract
The utility model discloses a dustproof blackboard eraser with a dust board. The dustproof blackboard eraser comprises a blackboard and a movable blackboard eraser body, wherein symmetrical frames are arranged at the left end and the right end of the blackboard, two ends of the movable blackboard eraser body are respectively located in corresponding frames, the dust board is arranged on the upper side wall of the movable blackboard eraser, and a dustproof cover is connected to the lower side wall of the movable blackboard eraser body. The dustproof blackboard eraser with the dust board is reasonable in structure and simple in manufacturing, chalk powder can be prevented from scattering when the blackboard eraser is used, the blackboard can be cleaned completely and quickly, and the dustproof blackboard eraser is convenient to use.
Description
Technical field
The utility model relates to a kind of assistant product of writing or draw, and is specifically related to a kind of dust-proof blackboard eraser with dust board.
Background technology
At present, most of school, blackboard and chalk still are main realia, however in teaching process, the letter written with chalk on the blackboard need be wiped through blackboard eraser commonly used.General blackboard eraser, its structure generally include wiping board and are fixed on the body of wiping of wiping board one side.This kind blackboard eraser can satisfy the demand of wiping letter written with chalk, but, it can produce a lot of chalk powders in use, part chalk powder can directly be sucked body interior by the student, some also can enter eyes, grown that to influence the student healthy the time, and the cleaning that this kind blackboard eraser can only small pieces one small pieces, cleaning efficiency is lower.
The shortcoming of prior art is: do not have dust board retaining chalk powder, the chalk powder of generation disperses everywhere, influences teacher and student's breathing environment, and cleaning that can only small pieces one small pieces, and cleaning efficiency is lower.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of and prevents that chalk powder from dispersing and the dust-proof blackboard eraser of the band dust board that can clean off a blackboard fast everywhere.
The technical solution of the utility model is as follows: a kind of dust-proof blackboard eraser with dust board, include blackboard and Active blackboard eraser, be provided with the frame of one group of symmetry at the two ends, the left and right sides of described blackboard, described Active blackboard eraser two ends lay respectively in the corresponding described frame, its key is: the upper side wall at described Active blackboard eraser is provided with dust board, lower wall at described Active blackboard eraser is connected with dust cover, like this blackboard eraser when up erasing the board because the effect of dust board, block the chalk powder that disperses, chalk powder is blocked in effect because of dust cover when down erasing the board, make chalk powder can not disperse everywhere, effectively overcome many deficiencies that traditional chalkboard eraser occurs.
The width of described dust board and dust cover is all consistent with the width of described Active blackboard eraser, so just can block the chalk powder that disperses out completely, makes that the practicality of blackboard eraser is stronger.
Be equipped with in described frame lower end and receive the dirt box, the described width of receiving the dirt box is consistent with the blackboard width, and chalk powder just directly drops to and receives dirt groove the inside and gone like this, and it is just passable only to need a periodic cleaning to receive the dirt groove.
Described dust cover is that elastic is made, and this dust cover one end connects described Active blackboard eraser lower wall, and the other end connects the described dirt box upper end of receiving, and can further block the chalk powder that falls down like this, thereby prevent that further chalk powder from dispersing everywhere.
Middle part at described Active blackboard eraser is provided with handle, can hold handle like this when mobile blackboard is wiped, and it is more convenient to use.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, makes simply, can avoid dispersing of chalk powder everywhere when in use, and can fast blackboard be cleaned out, and is very easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of as depicted in figs. 1 and 2 dust-proof blackboard eraser with dust board, include blackboard 1 and Active blackboard eraser 2, be provided with the frame 3 of one group of symmetry at the two ends, the left and right sides of described blackboard 1, described Active blackboard eraser 2 two ends lay respectively in the corresponding described frame 3, upper side wall at described Active blackboard eraser 2 is provided with dust board 4, lower wall at described Active blackboard eraser 2 is connected with dust cover 5, the width of described dust board 4 and dust cover 5 is all consistent with the width of described Active blackboard eraser 2, be equipped with in described blackboard lower end and receive dirt box 6, the described width of receiving dirt box 6 is consistent with the blackboard width, described dust cover 5 is made for elastic, these dust cover 5 one ends connect described Active blackboard eraser 2 lower wall, the other end connects described dirt box 6 upper ends of receiving, and is provided with handle 7 at the middle part of described Active blackboard eraser 2.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as: such conversion such as conversion that the conversion of baffle position, handle are provided with the position all fall within the protection domain of the present utility model.
