Abstract
The utility model discloses a convenient blackboard eraser system, which comprises a sliding component and an erasing component mounted on the sliding component. The erasing component comprises a blackboard eraser with the length slightly smaller than the width of a blackboard surface, and a handle is arranged on the blackboard eraser. The blackboard eraser is moved onto an area of the blackboard surface requiring erasure of writing along sliding rails and then moves along the sliding rails by pressing the handle, so that the writing can be erased conveniently. The whole process is simple, quick and convenient, and flying around of dust can be effectively avoided.
Description
Technical field:
The utility model relates to a kind of blackboard erasing system, relates in particular to a kind of portable blackboard erasing system that can remove the writing on the blackboard easily and quickly.
Background technology:
Blackboard is widely used a kind of instrument in teaching.At present, the method for deleting of blackboard is more single, only is to utilize a blackboard eraser to wipe.When the large tracts of land writing was arranged on the blackboard, this method for deleting was slower to the removing speed of blackboard.Particularly in science teaching, teacher's removing blackboard that often will stop had so both been wasted time in classroom, and also the thinking of awarding, listen to the teacher to the academics and students has caused influence.And, this erase mode need the eraser significantly vertical and horizontal saw the air, comparatively require great effort and the dust wiped is easy to directly get into eraser's respiratory system, cause the discomfort of respiratory system.For the higher writing in position, some eraser need could successfully wipe by foreign object pad pin, comparatively trouble and dangerous.
The utility model content:
In order to address the above problem, the utility model provides a kind of simple to operate, portable blackboard erasing system fast and effectively.
The technical scheme of the utility model is: portable blackboard erasing system, comprise that the slide assemblies machine is installed in the assembly of wiping on the slide assemblies, and the said assembly of wiping comprises a blackboard eraser, the length of said blackboard eraser is slightly less than the width of blackboard surface.
Said blackboard eraser is provided with handle.
Said slide assemblies comprises up and down two slide rails and is installed in the slide block on the slide rail, and last slide rail is installed on the metope above the blackboard, and glidepath is installed in the bottom of blackboard surface.
Said going up on slide rail and the glidepath respectively comprises two slide blocks, uses thin bar to connect between the slide block on the same slide rail.
Said glidepath adopts magnetic means to be pull-in on the bottom of blackboard surface.
Said glidepath adopts the viscosity mode to be bonded in the bottom of blackboard surface.
The said assembly of wiping also comprises two Metallic rod, and said Metallic rod is installed in parallel on the slide block of upper and lower slide rail.
Be connected fixing between said Metallic rod and the blackboard eraser through spring.
Said spring has four, is separately positioned on the blackboard eraser top and the bottom and leans on corner, and an end of spring is fixed on the blackboard eraser, and the other end is fixed on the Metallic rod.
The beneficial effect of the utility model is: portable blackboard eraser system in sum, to use simply, and erase process is convenient and swift.Blackboard eraser is moved to the zone that need wipe writing on the blackboard surface along slide rail, press handle, move, just can writing be wiped along slide rail, whole process, simple, fast and easy, and can effectively avoid dust to fly upward everywhere.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; Portable blackboard erasing system comprises that the slide assemblies machine is installed in the assembly of wiping on the slide assemblies, and the said assembly of wiping comprises a blackboard eraser 400; The length of blackboard eraser 400 is slightly less than the width of blackboard surface, and blackboard eraser 400 is provided with handle 410.Slide assemblies comprises up and down two slide rails 100 and is installed in the slide block 200 on the slide rail 100, and last slide rail 110 is installed on the metope above the blackboard, and glidepath 120 is installed in the bottom of blackboard surface.Respectively comprise two slide blocks 200 on last slide rail 110 and the glidepath 120, use thin bar 500 to connect between the slide block 200 on the same slide rail.Glidepath 120 can adopt magnetic means to be pull-in on the bottom of blackboard surface, also can adopt the viscosity mode to be bonded in the bottom of blackboard surface.Wipe assembly and also comprise two Metallic rod 300, Metallic rod 300 is installed in parallel on the slide block 200 of upper and lower slide rail 100.Be connected fixing through spring 600 between Metallic rod 300 and the blackboard eraser 400.Spring 600 has four, is separately positioned on blackboard eraser 400 top and the bottom and leans on corner, and an end of spring 600 is fixed on the blackboard eraser 400, and the other end is fixed on the Metallic rod 300.
During use, blackboard eraser is moved to the zone that need wipe writing on the blackboard surface along slide rail, press handle, move, just can writing be wiped along slide rail, whole process, simple, fast and easy, and can effectively avoid dust to fly upward everywhere.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
