Description

A kind of blackboard eraser takes off the dirt device
Technical field
The utility model is a kind of dirt device that takes off, and relates in particular to a kind of blackboard eraser and takes off the dirt device.
Background technology
Blackboard eraser can accumulate a large amount of chalk dusts in using for a long time, contain a variety of harmful materials in the chalk dust, and artificial beating is taken off dirt and can be caused second environmental pollution, and is totally unfavorable to teachers and students' health.This paper has introduced a kind of novel blackboard eraser and has taken off the dirt device, and the principle of utilization mechanical oscillation reaches the purpose of quick sealing dedusting.As everyone knows, chalk is made by land plaster and talcum powder, and the lacquer on blackboard surface is to contain a large amount of chemical substances: benzene and phenol.Therefore, chalk and the blackboard friction chalk dust that produces that writes is not single composition, but contains the benzene of trace and the mixing dust of phenol.Benzene and phenol are strong carcinogenic substances, and the lung and the liver of human body had very big harm, a few peoples even can get cancer, as seen its seriousness.In teaching process, owing to use blackboard eraser can accumulate a large amount of chalk dusts for a long time, the effect that letter written with chalk is wiped in influence normally will be carried out dedusting to it.Instructors adopted usually and patted the effect that blackboard eraser reaches dedusting in the past, but do like this chalk dust is spread in the air in a large number, cause the secondary pollution of classroom air, had a strong impact on teachers and students' health, and dedusting also can not reach good effect like this.
Set foot at present about the existing people of the problem of blackboard eraser dedusting, but product that all is that all right is ripe, that has developed mainly contains electric dust collector, two kinds of dust-removing blackboard erasers.These products are not the price height, are exactly that dust removing effects is poor, thereby all do not arrive general application.。
The utility model content
The utility model for solve the problems of the technologies described above provide a kind of simple in structure, volume is little, cost is low, environmental protection, a kind of blackboard eraser of good dedusting effect takes off the dirt device.
In order to overcome the defective of above-mentioned prior art, a kind of blackboard eraser of the utility model takes off the dirt device and comprises casing, clamping plate, fixed frame, wipe frame, tumbler, described clamping plate are connected with described box house one sidewall by two springs, described fixed frame is located at inherent described clamping plate bottom of described casing and both sides frame and described clamping plate two ends and is slidingly connected, described fixed frame and described bottom half are connected and fixed with spring, and described wiping frame is located at described fixed frame bottom and described fixed frame is slidingly connected, and described wiping circle body is provided with the identical rotating shaft of several sizes, one slip limit of described wiping frame connects described tumbler
Described tumbler comprises rocking bar, gear wheel, pinion, cam, described rocking bar is located in the described casing and is rotationally connected with described casing both sides, one end passes affixed one and shakes handle, described gear wheel is installed on the described rocking bar, described bottom half is established a support bar, and rolling on described support bar wears a rotating shaft, is installed with pinion on an end of described rotating shaft and gear wheel homonymy, cam, described pinion and described gear wheel are meshing with each other, and another termination of described rotating shaft sets firmly a guide rod, and a slip limit of described guide rod and described wiping frame homonymy is affixed.
Described fixed frame sets firmly a jacking block and corresponding with described cam in the bottom on one side.
Described bottom half is provided with a dust collecting box can extract casing out.
The utility model is to promote fixture block blackboard eraser is placed between clamping plate and the fixed frame clamps, manpower shakes handle moves around the wiping frame of gear wheel rotation driving pinion rotation drive guide rod connection, wipe rotating shaft and blackboard eraser on the frame and need take off the dirt face and rub back and forth and take off dirt, cam also rotates jack-up fixed frame generation vertical tremor and makes dust drop to dust collecting box under shock effect simultaneously.
In sum, the utlity model has following beneficial effect:
1, simple in structure, easy to use;
2, volume is little, cost is low, environmental protection;
3, good dedusting effect.
Description of drawings
Fig. 1 takes off the structural representation of dirt device for a kind of blackboard eraser of the utility model;
Fig. 2 takes off the back pseudosection of dirt device for a kind of blackboard eraser of the utility model.
Wherein: 1, casing; 2, clamping plate; 3, fixed frame; 4, wipe frame; 5, rocking bar; 6, gear wheel; 7, pinion; 8, cam; 9, shake handle; 10, support bar; 11, guide rod; 12, dust collecting box; 13, jacking block.
The specific embodiment
As Fig. 1, one one kinds of blackboard erasers shown in Figure 2 take off the dirt device and comprise casing 1, clamping plate 2, fixed frame 3, wipe frame 4, tumbler, described clamping plate 2 are connected with described casing 1 an inner sidewall by two springs, described fixed frame 3 is located at described casing 1 inherent described clamping plate 2 bottoms and both sides frame and described clamping plate 2 two ends and is slidingly connected, described fixed frame 3 is connected and fixed with spring with described casing 1 bottom, described wiping frame 4 is located at described fixed frame 3 bottoms and described fixed frame 3 is slidingly connected, described wiping frame 2 frameworks are provided with the identical rotating shaft of several sizes, and a slip limit of described wiping frame 2 connects described tumbler
Described tumbler comprises rocking bar 5, gear wheel 6, pinion 7, cam 8, described rocking bar 5 is located in the described casing 1 and is rotationally connected with described casing 1 both sides, one end passes affixed one and shakes handle 9, described gear wheel 6 is installed on the described rocking bar 5, a support bar 10 is established in described casing 1 bottom, and rolling on described support bar 10 wears a rotating shaft, is installed with pinion 7 on an end of described rotating shaft and gear wheel 6 homonymies, cam 8, described pinion 7 is meshing with each other with described gear wheel 6, and another termination of described rotating shaft sets firmly a guide rod 11, and described guide rod 11 is affixed with a slip limit of described wiping frame 4 homonymies.
