Abstract
A blackboard eraser with a dust collection function for English teaching mainly solves the problem that an existing teaching blackboard eraser is of a simple structure with a banister brush and a bottom plate and does not have a dust collection function. The blackboard eraser is characterized in that an upper sliding way and a lower sliding way are fixed at the upper end and the lower end of a blackboard respectively, an upper pulley and a lower pulley are embedded into the upper sliding way and the lower sliding way respectively, a connecting frame is elongated, the upper end and the lower end of the connecting frame are fixed to the upper pulley and the lower pulley respectively through a connecting shaft, a hollow box is fixed on the inner side of the connecting frame, the upper end and the lower end of the box are connected with an upper dust collection box and a lower dust collection box through pins, a soft cloth brush is fixed on the inner side of the box, and a dust receiving groove is formed in the upper end of the lower sliding way. The blackboard eraser is novel in structure, simple to operate and high in practicability, chalk dust is collected by the dust receiving groove, the collected chalk dust can be recycled and manufactured into chalks again, energy is saved, and environments are protected.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of aided education office device be applied in English teaching use.
Background technology
Blackboard is very important instrument in teaching process, blackboard totally whether can affect quality of instruction.Using at present in the English teaching field is only the structure that banister brush simple in structure adds base plate for the blackboard eraser that teacher's writing on the blackboard is used is provided, and does not possess dust-absorbing function.Because process of English teaching needs a large amount of writings on the blackboard, the teacher at school during, can take up a large amount of dust when erasing the board, affected to a great extent the healthy of teacher.
Summary of the invention
In order to solve the technical problem of mentioning in background technology, the utility model provides a kind of blackboard eraser with dust-absorbing function for English teaching, this kind of blackboard eraser aims at the English teacher and imparts knowledge to students with design, can be when the teacher erases the board, dust is sucked to dust-absorbing box, guaranteed that preferably the English teacher's is healthy.
The technical solution of the utility model is: this kind, for the blackboard eraser with dust-absorbing function of English teaching, comprises blackboard, link and upper and lower dust collecting box; Its unique distinction is: the upper/lower terminal of described blackboard is fixed with respectively sliding way and glide path, is embedded with respectively top sheave and lower sheave in described sliding way and glide path; Described link is strip, upper and lower end is fixed by connecting axle and top sheave and lower sheave respectively, the inboard of link is fixed with the box body of hollow, and the two ends up and down of described box body are connected with upper dust collecting box and lower dust collecting box by bearing pin, and the inboard of box body is fixed with soft cloth brush; The upper end of described glide path is provided with the dust receiving slit; Described upper dust collecting box be equipped with respectively hollow shaft micro machine and the hollow dust absorption fan be connected by shaft coupling in lower dust collecting box, the sidewall of dust suction box body has the dust inlet hole, and the sweep-up pipe linked with the hollow shaft of described micro machine is drawn and put in box body by dust suction box body end.
In addition, a small blackboard is set on described blackboard and wipes, described small blackboard is wiped inboard sponge and is provided with grey hole, while for teacher, attending class the local wiping of process, uses; Be fixed with the handle of two differing heights on described link, the teacher can select suitable handle to horizontally slip according to height, can facilitate blackboard wiping.
The utlity model has following beneficial effect: this kind consists of blackboard, slideway, pulley and dust collecting box for the blackboard eraser with dust-absorbing function of English teaching, and upper lower sheave all can move on slideway, facilitates teacher's use; The teacher is when erasing the board, and hollow shaft micro machine and the hollow dust absorption fan of dust collecting box inside are worked simultaneously, will automatically siphon away the dust filled the air, and have guaranteed the health of teacher's health; Collect the pen ash by the dust receiving slit, the chalk dust recoverable of collection is made chalk again and is used, energy-conservation environmental protection again.The apparatus structure novelty, easy to use, there is stronger practicality.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
1-blackboard in figure, the 2-sliding way, the 3-glide path, the 4-top sheave, the 5-lower sheave, the 6-link, the 7-box body, the upper dust collecting box of 8-, dust collecting box under 9-, the 10-handle, 11-dust receiving slit, the 12-small blackboard is wiped, the 13-soft cloth brush.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1, in conjunction with shown in Fig. 2, this kind, for the blackboard eraser with dust-absorbing function of English teaching, comprises blackboard 1, link 6 and upper and lower dust collecting box 8,9; Its unique distinction is: the upper/lower terminal of described blackboard 1 is fixed with respectively sliding way 2 and glide path 3, interior top sheave 4 and the lower sheave 5 of being embedded with respectively of described sliding way 2 and glide path 3; Described link 6 is strip, upper and lower end is fixing by connecting axle and top sheave 4 and lower sheave 5 respectively, the inboard of link 6 is fixed with the box body 7 of hollow, the two ends up and down of described box body 7 are connected with upper dust collecting box 8 and lower dust collecting box 9 by bearing pin, and the inboard of box body 7 is fixed with soft cloth brush 13; The upper end of described glide path 3 is provided with dust receiving slit 11; Described upper dust collecting box 8 and interior hollow shaft micro machine and the hollow dust absorption fan be connected by shaft coupling of being equipped with respectively of lower dust collecting box 9, the sidewall of dust suction box body has the dust inlet hole, and the sweep-up pipe linked with the hollow shaft of described micro machine is drawn and put in box body 7 by dust suction box body end.
In addition, small blackboard is set on described blackboard 1 and wipes 9, described small blackboard is wiped 9 sponge and is provided with grey hole, for teacher's local wiping of process of attending class, only uses; Be fixed with the handle 10 of two differing heights on described link 6, the teacher can select suitable handle to horizontally slip according to height, can facilitate blackboard wiping, has avoided, because existing chalkboard eraser is too small, need to constantly brandishes arm and also being difficult to the phenomenon of wiping clean.
During application, on blackboard by this kind of device in classroom, fix, serve as a teacher when erasing the board, switch on power and control circuit, hollow shaft micro machine and hollow dust absorption fan are worked simultaneously, can automatically the dust filled the air be sucked to dust collecting box, afterwards can be by being connected in box body 7 tops and deriving with the sweep-up pipe that the micro machine hollow shaft links.Can clear up dust after finally box body 7 being taken out.
