Abstract
The utility model relates to the field of teaching tools, in particular to an environment-friendly magnetic blackboard which is excellent in cleaning effects and dust-free. The environment-friendly magnetic blackboard comprises a blackboard body, the lower end of the blackboard body extends crosswise and outward to form a boss, magnetic blackboard brushes are arranged on the boss, drawing mechanisms drawing the magnetic blackboard brushes to move up and down are arranged at the upper end of the blackboard body, and the lower ends of the drawing mechanisms are connected with the magnetic blackboard brushes. According to the technical scheme, the drawing mechanisms drive the magnetic blackboard brushes to move up and down so as to clean writing board faces of the blackboard, so that the cleaning effects are improved, and air is prevented from being polluted by produced dust.
Description
Technical field
The utility model relates to the teaching aid field, is specifically related to a kind of environmental protection magnet board
Background technology
At present, the most of schools of China popularize to use electronic projection apparatus yet, the blackboard educational aid that still is absolutely necessary.During the teaching, always unavoidably wipe blackboard several times, the blackboard that has is difficult to wipe clean, and influences the writing effect of blackboard, and chalk dust aloft flies upward everywhere, and teacher and classmate's health is brought injury.
The utility model content
The purpose that the utility model solves provides that a kind of wiping effect is good, a kind of environmental protection magnet board of dustless environmental protection.
The technical scheme that the utility model adopts; A kind of environmental protection magnet board comprises plate body, and the lower end of plate body laterally is outward extended with boss, and the magnetic scrubbing brush is set on the boss; The upper end of plate body is provided with and pulls the haulage gear that magnetic sheet brushes down motion, and the lower end of haulage gear is connected with the magnetic scrubbing brush.
Through above technical scheme, drive magnetic sheet through haulage gear and brush down motion, the clipboard face of blackboard is carried out wiping, not only improved the effect of wiping, and avoided of the pollution of the dust of generation air.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the side view of the utility model;
Fig. 3 is the structural representation of haulage gear.
The specific embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1,2,3.
A kind of environmental protection magnet board comprises plate body 10, can be used for teaching writing on the plate body 10; The lower end of said plate body 10 laterally is outward extended with boss 11; Magnetic scrubbing brush 20 is set on the boss 11, and the effect of boss 11 is magnetic scrubbing brush 20 to be held in the palm effectively hold up, and it can not fallen from plate body 10.The upper end of plate body 10 is provided with and pulls the haulage gear 30 that magnetic scrubbing brush 20 moves up and down; The lower end of haulage gear 30 is connected with magnetic scrubbing brush 20; Magnetic scrubbing brush 20 is under the effect of haulage gear 30; Motion from the bottom up, thus the writing on the plate body 10 is wiped totally, and wiping returns the home position after accomplishing.
Specifically, described haulage gear 30 comprises fixed pulley 31, and fixed pulley 31 is located at the upper end sidepiece of plate body 10, and fixed pulley 31 is provided with stay cord 32, and an end of stay cord 32 is located on the magnetic scrubbing brush 20, and the other end is the sidepiece that the shape that suspends is revealed in plate body 10.During use, only need pulling stay cord 32 just can spur magnetic scrubbing brush 20 and on plate body 10, do elevating movement, reach the purpose of wiping plate body 10.
In order to strengthen the wiping effect of 20 pairs of plate bodys 10 of magnetic scrubbing brush, described magnetic scrubbing brush 20 is a strip, and magnetic scrubbing brush 20 fits tightly along the length direction setting of plate body 10 and with the clipboard face of plate body 10.
Further, prevent in the process of pulling stay cord 32 that in order to make because stay cord 32 rocks the swing that causes magnetic scrubbing brush 20, thereby influence wiping effect, the lower end of described stay cord 32 is provided with slide block 33, slide block 33 is connected with magnetic scrubbing brush 20.
Further, the installation of slide block 33 and motion for ease, described plate body 10 is hollow shape, slide block 33 is located in the gap between the upper and lower plate face of plate body 10.Like this, good spacing guide effect had just both been played to slide block 33 in the gap between the upper and lower plate face of plate body 10, had also prevented rocking of slide block 33 effectively, makes it remain straight line, thereby magnetic scrubbing brush 20 can not swung on the plate face of plate body 10.
Write to satisfy the needs of teaching for the ease of piecemeal, the plate face middle part of described plate body 10 is provided with along its width cuts apart plate 12.Cut apart plate 12 the plate face of plate body 10 is divided into left and right sides two parts, can select the branch column to write so as required.
Further, corresponding with it, described magnetic scrubbing brush 20 is two, is located at the both sides of demarcation strip 12 respectively, respectively demarcation strip 12 twice plate faces is carried out wiping.
Further, described haulage gear 30 is symmetrically set in the upper end of the both sides of plate body 10, and haulage gear 30 is respectively to 20 draws of magnetic scrubbing brush.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
