Description
Technical field
The utility model relates to a kind of blackboard eraser, relates in particular to a kind of roller dust-proof blackboard eraser.
Background technology
At present, generally the blackboard eraser of Shi Yonging is to be close to blackboard surface to move back and forth the purpose that realizes wiping the blackboard panel chalk trace under manually-operated, waste time and energy, the chalk dust contaminated environment of kicking up in the classroom simultaneously, it is healthy to influence teachers and students, and a large amount of chalk dusts are bonded at that to cause wiping grey effect on the blackboard eraser very undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of roller dust-proof blackboard eraser, to overcome above-mentioned shortcoming.
Technical solution of the present utility model is the method that adopts dust cover, wiping roller and ash collecting box to combine, and the chalk dust under wiping is collected in the ash collecting box, accomplishes that neither dust again can be clean with blackboard eraser.
The utility model comprises support, wipes roller and dust cover, it is characterized in that:
On A, the described support 1, dust cover 2 arranged, wipe roller 3 and rail wheel 4, wipe roller 3 and place in the dust cover 2, rail wheel 4 is the clamping shape with the track 6 of blackboard 5 both sides;
B, described wiping roller 3 are made up of rotating shaft and wiper, and an end of rotating shaft 7 is connected with driver 8, and the coated outside of rotating shaft 7 has wiper 9;
There is ash collecting box 10 lower end of C, described dust cover 2.
Described driver 8 is bunchers.
Described driver 8 is pinion and racks.
The utility model has the advantages that wipe roller under the drive of driver (electronic or manual) along the reciprocal erasing of blackboard surface; chalk dust under wiping is collected in the ash collecting box of dust cover lower end; accomplish that neither dust again can be clean with blackboard eraser, protected that environment in the classroom and teachers and students' is healthy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is embodiment of the utility model (buncher is connected with the wiping roller) schematic diagram.
Fig. 3 is another embodiment of the utility model (pinion and rack is connected with the wiping roller) schematic diagram.
Among the figure: the 1-support, the 2-dust cover, 3-wipes roller, 4-rail wheel, 5-blackboard, 6-track, 7-rotating shaft, 8-driver, 9-wiper, 10-ash collecting box, 11-press button, 12-buncher, 13-shaft coupling, 14-gear, 15-tooth bar.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-3, dust cover 2 is arranged on the support 1, wipe roller 3 and rail wheel 4, to wipe roller 3 and place in the dust cover 2, rail wheel 4 is the clamping shape with the track 6 of blackboard 5 both sides; Described wiping roller 3 is made up of rotating shaft and wiper, and an end of rotating shaft 7 is connected with driver 8, and the coated outside of rotating shaft 7 has wiper 9; There is ash collecting box 10 lower end of described dust cover 2.When employing is electronic; driver 8 is bunchers; when employing is manual; driver 8 is pinion and racks; no matter be electronic and manual; wipe roller 3 under the drive of driver 8; fast rotational is also wiped clean the chalk trace on the blackboard 5 in the mode of rolling erasing by the wiper 9 of rotating shaft 7 outsides; wiping chalk dust down falls in the following ash collecting box 10 of dust cover 2; regularly topple over; thereby the environment to the classroom does not constitute pollution; protected that teachers and students' is healthy; support 1 is by rail wheel 4; track 6 can be along the track side-to-side movement of blackboard 5 both sides, and this motion is because the reaction force that wiping roller 3 produces when the erasing blackboard is realized, does not need other power.
