Description
Technical field
The utility model relates to a kind of teaching and uses incorporate device for blackboard eraser.
Background technology
Erase the board in traditional teaching process all is to be accomplished by common hand held blackboard eraser; It is clean with blackboard eraser with holding the blackboard eraser piecemeal that its whole process all needs teacher or student to wave arm; The major defect one of this hand held blackboard eraser is an effort: for blackboard is cleaned; Whole erase process must be exerted oneself by arm, wipes whole blackboard like this and can make that the whole piece arm is aching and tired, and the probability that everyday so makes the teacher suffer from scapulohumeral periarthritis increases greatly; The 2nd, contaminated environment, to influence teachers and students healthy: a large amount of dust descend slowly and lightly when erasing the board, and are sucked respiratory tract by teachers and students and get into lung, if things go on like this influence healthy.
Summary of the invention
The utility model technical problem to be solved provides a kind of simple in structure, economical and practical incorporate device for blackboard eraser that has.
For solving this technical problem, the utility model adopts following technical scheme:
The utility model comprises blackboard eraser and blackboard; Said blackboard eraser and blackboard are connected to the integrative-structure of fricting movement relatively through pulley structure; Said blackboard eraser is a strip, and its height is with identical with blackboard, and it is provided with pulley in two ends up and down; The last lower edge of said blackboard is provided with slide rail, and the blackboard eraser that has pulley can horizontally slip on blackboard along this slide rail.
Be provided with connecting plate, connecting axle, pulley and alignment pin in the said pulley structure, said connecting axle one end is provided with limiting stand, and the other end radially is provided with dowel hole, and said pulley, connecting plate, pulley are installed on the connecting axle successively, inserts alignment pin; The other end of said connecting plate is provided with bolt hole, is connected through bolt with blackboard eraser.
The both sides of said blackboard eraser are provided with in order to stop chalk dust ash baffle plate, and said baffle plate is consistent with the blackboard eraser height.
The bottom of said blackboard eraser is provided with the kerve that is used to receive the chalk dust ash, and this kerve is circular-arc and is upturned, and its width is greater than the width of blackboard eraser two side shields.
Said blackboard eraser width is 60 ~ 100mm, hairbrush apart from border, the left and right sides 8 ~ 10 mm side by side three row evenly be arranged on the blackboard eraser; Said blackboard eraser back is provided with handle, and this handle height is 2/3 of the whole length of blackboard eraser.
The beneficial effect of the utility model is: adopt pulley to connect and the ingenious combination of baffle arrangement, the feasible process that erases the board is time saving and energy saving and avoid effectively that the powder ash flies upward, unhealthful situation.

Among the figure: 1 blackboard eraser, 2 pulleys, 3 kerves, 4 baffle plates, 5 slide rails, 6 blackboards, 7 connecting plates, 8 connecting axles, 9 alignment pins, 10 handles, 11 hairbrush.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Figure 1 is the structural representation of the utility model.
The utility model comprises blackboard eraser 1 and blackboard 6; Also comprise pulley structure, said blackboard eraser 1 is the strip identical with the height of blackboard 6, and it is provided with pulley 2 in two ends up and down; The last lower edge of said blackboard 6 is provided with slide rail 5; Blackboard eraser 1 can horizontally slip along slide rail 5, and this structure can guarantee blackboard eraser 1 along the guide rail activity freely, erase the board 6 o'clock time saving and energy saving.
The both sides of said blackboard eraser 1 are provided with in order to stop chalk dust ash baffle plate 4, and said baffle plate 4 is consistent with the height of blackboard eraser 1.
The bottom of said blackboard eraser 1 is provided with the kerve 3 that is used to receive the chalk dust ash; This kerve 3 is circular-arc and is upturned; Its width is greater than the distance of 1 liang of side shield 4 of blackboard eraser, kerve 3 be contained in blackboard eraser 1 and baffle plate 4 bottoms can be undertaken on directly drop in the process of erasing the board from the bristle slit or rely on baffle plate 4 to stop the chalk dust ash of landing.
Be provided with connecting plate 7, connecting axle 8, pulley 2 in the said pulley structure; Said pulley 2 is arranged on the connecting axle 8; One end of this connecting axle 8 is designed with the position that a boss is used for limiting pulley 2; The other end is provided with dowel hole, and pulley 2 and connecting plate 7 are assembled to back installing and locating pin 9 on the connecting axle 8, and anti-limited slip wheel 2 drops from connecting axle 8.
The width of said blackboard eraser 1 is 60 ~ 100mm, hairbrush 11 apart from border, the left and right sides 8 ~ 10mm side by side three row evenly be arranged on the blackboard eraser 1, blackboard eraser 1 back is provided with handle 10, makes things convenient for people's hand control to erase the board, this handle length is 2/3 of blackboard eraser 1 a whole height.
During installation: pulley 2 is sleeved on the connecting axle 8 position that is used for limiting pulley 2 near boss, is assembled on the connecting axle 8 back to pulley 2 and connecting plate 7 alignment pin 9 is installed; Blackboard eraser 1 is placed on blackboard 6 left sides, connects blackboard eraser 1 and connecting plate 7 with bolt, again through pulley 2 is placed in the slide rail 5 at blackboard 6 two ends, thereby blackboard eraser 1 and blackboard 6 is linked up; Load onto end cap at the two ends of slide rail 5 to prevent blackboard eraser 1 landing in drawing process; Kerve 3 this moment, also card was placed on blackboard eraser 1 bottom.
When erasing the board: the handle 10 that only needs grasping to live blackboard eraser 1 back just can rely on the sheave of 6 on blackboard eraser 1 and blackboard to realize simple reciprocal the pulling; Overcome original hard and aching and tired phenomenon of arm; And pulling once just can be wiped the font vestige of whole blackboard 6; Two side shields 4 can effectively suppress the chalk dust ash that erase process is kicked up; In the kerve 2 that two side shields, 4 smooth surfaces can be impelled the chalk dust ash to take advantage of a situation to be slipped to the bottom, avoid the dirt ash to disperse at the secondary from the process that falls earthward in midair.Not only effectively saved manpower but also controlled the dust pollution air, can take off kerve 3 after use a period of time, directly poured the dust of the inside into dustbin, the whole process that erases the board is simple at this point easily to be accomplished.
