The technical scheme of the utility model is: this kind English teaching is used the dust suction chalkboard eraser; Constitute by guide rail that is fixed in the blackboard upper/lower terminal and dust-absorbing box; Its unique distinction is: said guide rail is divided into upper rail and lower guideway two parts, and said dust-absorbing box also is divided into dust-absorbing box and following dust-absorbing box two parts, and last dust-absorbing box is connected with the box body of following dust-absorbing box through hollow; Be fixed with connecting plate on the box body, the upper and lower end of said connecting plate passes through connecting axle fixedly upper block and lower tumbler respectively; Said upper block and lower tumbler match with upper rail and lower guideway respectively and horizontally slip along guide rail with realization; The inboard of said box body is fixed with the soft cloth brush; Be equipped with hollow shaft micro machine and the hollow dust absorption fan that is connected through shaft coupling respectively in last dust-absorbing box and the following dust-absorbing box; The sidewall of dust suction box body has the dust inlet hole, and the sweep-up pipe that links with the hollow shaft of said micro machine is drawn by dust suction box body end to be put in the box body.
In addition, teacher's use for ease for bearing pin is connected, can be dismantled between dust-absorbing box and the box body, convenient dust of deriving in the dust-absorbing box.And, being connected with handle at upper junction plate, the teacher can hand and horizontally slip, and can make things convenient for blackboard wiping.
The utlity model has following beneficial effect: this kind English teaching is made up of guide rail and dust-absorbing box with the dust suction chalkboard eraser, and two parts about the dust-absorbing box branch, all can on guide rail, move, and makes things convenient for teacher's use.And the teacher is when erasing the board, and inner hollow shaft micro machine and the hollow dust absorption fan of dust-absorbing box worked simultaneously, with siphoning away the dust that fills the air automatically, guaranteed the health of teacher's health.Apparatus structure is novel, and is easy to use, has stronger practicality.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
1-blackboard among the figure, 2-upper rail, the last dust-absorbing box of 3-, 4-upper block, 5-connecting plate, 6-handle, 7-box body, dust-absorbing box under the 8-, 9-lower tumbler, 10-lower guideway.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; This kind English teaching is used the dust suction chalkboard eraser, is made up of the guide rail and the dust-absorbing box that are fixed in blackboard 1 upper/lower terminal, and its unique distinction is: said guide rail is divided into upper rail 2 and lower guideway 10 2 parts; Said dust-absorbing box also is divided into dust-absorbing box 3 and following dust-absorbing box 8 two parts; Last dust-absorbing box 3 is connected with the box body 7 of following dust-absorbing box 8 through hollow, is fixed with connecting plate 5 on the box body 7, and the upper and lower end of said connecting plate 5 passes through connecting axle fixedly upper block 4 and lower tumbler 9 respectively; Said upper block 4 matches with upper rail 2 and lower guideway 10 respectively with lower tumbler 9 and horizontally slips along guide rail with realization.The inboard of said box body 7 is fixed with the soft cloth brush; Be equipped with hollow shaft micro machine and the hollow dust absorption fan that is connected through shaft coupling respectively in last dust-absorbing box 3 and the following dust-absorbing box 8; The sidewall of dust suction box body has the dust inlet hole, and the sweep-up pipe that links with the hollow shaft of said micro machine is drawn by dust suction box body end to be put in the box body 7.
During application; With fixing on the blackboard of this kind device in the classroom; Serve as a teacher when erasing the board, energized and control circuit, hollow shaft micro machine and hollow dust absorption fan are worked simultaneously; Can automatically the dust that fills the air be sucked dust-absorbing box, afterwards can be through being connected in the box body top and deriving with the sweep-up pipe that the micro machine hollow shaft links.Can clear up dust after at last box body being taken out.
In addition; Teacher's use for ease; For bearing pin is connected, can dismantle between dust-absorbing box and the box body, the teacher not only derives the dust in the dust-absorbing box like this; And can carry out irregular maintenance and maintenance to the micro machine and the dust absorption fan of dust-absorbing box inside, exempted because long-term work micro machine and the not good situation of dust absorption fan work.
In addition, can on connecting plate, be connected with handle, the teacher can hand handle and horizontally slip, and can make things convenient for blackboard wiping.Avoided constantly to brandish arm and also being difficult to the phenomenon wiped clean because existing chalkboard eraser is too small.
