Brief description of the drawings
The application schematic diagram of the dust-free black board eraser that Fig. 1 provides for the utility model embodiment.
Fig. 2 is the part-structure schematic diagram of dust-free black board eraser in Fig. 1.
Main symbol description: guide rail 1, crossbeam 2, slide block 3, cover box 4, dress dirt case 5, hairbrush 6, lever 7, blackboard 8, bolt 9.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the utility model discloses a kind of dust-free black board eraser, it is for clean blackboard 8.This dust-free black board eraser comprises two guide rails 1, crossbeam 2, two slide blocks 3, cover box 4, dress dirt case 5.In the present embodiment, definition perpendicular to the direction of gravity be upper and lower to, the direction that is parallel to gravity is left and right direction, therefore, upper and lower, left and right direction ratio is hereinafter clearer and more definite.
Article two, guide rail 1 is set in parallel on the upper and lower relative dual-side of blackboard, and two slide blocks 3 are arranged on respectively on two guide rails 1 and can slide by relatively corresponding guide rail 1, and therefore, two slide blocks 3 can freely left and right slip on corresponding guide rail 1.
The two ends of crossbeam 2 are separately fixed on two slide blocks 3 and move by being guided on two guide rails 1 of two slide blocks 3, therefore, two slide blocks 3 link together by crossbeam 2, slide to the left or to the right, and drive crossbeam 2 to move together when mobile along two guide rails 1 simultaneously.
Incorporated by reference to Fig. 2, crossbeam 2 is provided with the hairbrush 6 for clean this blackboard towards a side of this blackboard 8, cover box 4 is fixed on crossbeam 2, one end of hairbrush 6 is housed in cover box 4 and the other end extends cover box 4, hairbrush 6 is when clean like this, dust can not drop out, and can relatively concentrate in cover box 4, reaches the object of concentrating dust.The bottom of cover box 4 is provided with dress dirt case 5, and dress dirt case 5 communicates with cover box 4, and like this, the dust energy freely falling body concentrating in cover box 4 falls in dress dirt case 5, completes automatic collection.Therefore, realized dust and focused on and reach dustless effect, thereby the dust producing in 8 the process of avoiding erasing the board brings the harm of self to teacher classmate, have the effect of environmental protection; Simple in structure being easy to installed, easy to operate.Since one end of hairbrush 6 is housed in cover box 4, the width that covers so box 4 is certainly large than the width of hairbrush 6, to how wide degree, sees the intensity of dust in cover box 4 as for large.
Cover box 4 can be plastic casing, and cover box 4 can be fixed on crossbeam 2 by bolt 9, certain, and in other embodiments, cover box 4 also can be fixed on crossbeam 2 by screw or viscose, as long as cover box 4 can be secured on crossbeam 2.
For the ease of cleaning dress dirt case 5, dress dirt case 5 can be designed to detachable, as, dress dirt case 5 is sticked on crossbeam 2, while cleaning like this, only dress dirt case 5 need to be separated to crossbeam 2, when use, be fastened on crossbeam 2; Can also be designed to drawable, as, dress dirt case 5 comprise be fixed on cover box 4 bottoms housing, be housed in the drawer in this housing, this drawer relatively this housing detachably for collecting dust.
In addition, for user-friendly dust-free black board eraser, a crossbeam 2 dorsad side of hairbrush 6 can be provided with lever 7, uses so more laborsaving.
Dust-free black board eraser of the present utility model in use, user can make crossbeam 2 be with the clean blackboard 8 of electric brush 6 by promoting lever 7, dust on blackboard 8 is wiped out, because the left and right relative both sides quilt cover box 4 of hairbrush 6 seals, therefore, dust can not splash everywhere, only can automatically concentrate in cover box 4, fall in the dress dirt case 5 of cover box 4 bottoms from the interior freely falling body of cover box 4, realize the automatic collection of dust.In addition, dress dirt case 5 can be detachable can be also drawable, therefore, can after wiping, extract out and outwell dust, very convenient.
In sum, crossbeam 2 with hairbrush 6 is connected through bolt 9 with cover box 4, thereby reach the situation of acting in agreement, the hairbrush 6 of dust-free black board eraser reaches the effect of wiping meal dirt through the movement of guide rail 1, and the plastic jacket box 4 of sealing do not coming off outside dust, a dress dirt case 5 is set below and plays the effect of accepting dust and twitch dress dirt case 5 to reach cleaning dust.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
