Description
Technical field
The utility model blackboard eraser belongs to instructional device technical field, and in particular to blackboard eraser.
Background technology
When erasing the board, using traditional blackboard eraser, with when the dust on blackboard brush excessively causes to erase the board
Not clean enough, and dust can float in atmosphere, chalk dust is full of in whole classroom, for the health of Faculty and Students
It will have a certain impact.
Utility model content
The purpose of the utility model blackboard eraser is：Blackboard eraser is aimed to provide, for solving existing blackboard eraser in the process used
In, the problem of dust influences Faculty and Students' health can be produced.
To realize above-mentioned technical purpose, the utility model uses the technical scheme of blackboard eraser as follows：
Blackboard eraser, including shell, the shell is interior to be provided with upper division board and lower division board, the upper division board and lower isolation
The inside of shell is divided into upper isolated area, middle isolated area and lower isolated area by plate, if the both sides up and down of the upper isolated area are equipped with
Dry projection, the both sides up and down it is raised corresponding, the projection is spherical structure, and the left and right sides in the shell is equipped with
Three chutes, the longitudinal section of the chute is semicircular structure, and the side of the close enclosure of the chute is provided with opening, institute
The front end for stating opening is provided with locking member, and the chute of the left and right sides is corresponding in same level, the upper isolated area, in
Isolated area and lower isolated area are equipped with two-sided wiping board, and the both sides of the two-sided wiping board are provided with the draw runner to match with chute, described
Two surfaces up and down of two-sided wiping board are provided with wiper, and the outside of the two-sided wiping board is provided with otic placode.
Using the utility model of above-mentioned technical proposal, using the wiper to be washed and brush before blackboard eraser on two-sided wiping board, wash
Every piece of two-sided wiping board slides up and down several times in upper division board during brush, raised one side cleaning and wiping on this when of isolated area mouth both sides
Cloth, while extruding wiper excludes water, keep the dampness of wiper appropriateness.During using blackboard eraser to erase the board, three pieces two-sided
Wiping board is filled in three chutes in isolated area, middle isolated area and lower isolated area respectively, is then locked with locking member, wipes
During blackboard, the wiper after three pieces of two-sided wiping board installations simply on the lower surface of nethermost one piece of two-sided wiping board can be contacted black
Plate, during this face wiper of Reusability, the chalk of mud can adhere to wiper, will result in blackboard eraser obtain it is unclean, at this time I
Can extract the two-sided wiping board of this part it is turned over and be again introduced into lower isolated area, that wiper being dirty translates into back,
Clean another side wiper translates into bottommost, and after the clean wiper in this face is also dirty, we can make interval from area
Two-sided wiping board transposition on two-sided wiping board and lower isolated area, the two-sided wiping board of this block is also by two-sided with the 3rd piece again after use
Wiping board transposition.The clean state of blackboard can thus be kept and avoid producing dust.If once teaching erasing blackboard number
It is more, all wiper faces of all two-sided wiping boards are finished, we can clean blackboard eraser again and carry out Reusability.So, blacking
During plate, there will be no dust appearance, reduces influence of the dust to Faculty and Students' health.
Further limit, the two-sided wiping board is slab construction, and the thickness of the two-sided wiping board is 3mm~8mm, such
Design, can more neatly erasing blackboard surface.
Further limit, the otic placode is provided with through hole, and the diameter dimension of the through hole is 15mm~25mm, such to set
Meter, more convenient when in use it can take out two-sided wiping board.
Further limit, the distance between two adjacent projections of the homonymy is equal sized and is 10mm~20mm, so
Design, cleaning when, wiper is more prone to be extracted.
Further limit, the rear end of the draw runner is provided with guide head, such design, can put preferably two-sided wiping board
In in upper isolated area, middle isolated area or lower isolated area.
Further limit, the length dimension * width dimensions * height dimensions of the blackboard eraser are 120mm~200mm*40mm
~120mm*20mm~80mm, such design, during use more smoothly, more comfortably.
Brief description of the drawings
The utility model can be further illustrated by the nonlimiting examples that accompanying drawing provides；
Fig. 1 is the structural representation of the utility model blackboard eraser embodiment；
Main element symbol description is as follows：Shell 1, upper isolated area 11, middle isolated area 12, lower isolated area 13, upper division board
14th, lower division board 15, projection 16, chute 2, two-sided wiping board 3, draw runner 31, wiper 32, otic placode 33, through hole 34.
Embodiment
In order that the utility model may be better understood in those skilled in the art, it is right with reference to the accompanying drawings and examples
Technical solutions of the utility model further illustrate.
As shown in figure 1, blackboard eraser of the present utility model, including shell 1, shell 1 is interior to be provided with upper division board 14 and lower isolation
The inside of shell 1 is divided into upper isolated area 11, middle isolated area 12 and lower isolated area by plate 15, upper division board 14 and lower division board 15
13, the both sides up and down of upper isolated area 11 are equipped with some raised 16, and the projection 16 of upper and lower both sides is corresponding, and projection 16 is spherical junctions
Structure, the left and right sides in shell 1 are equipped with three chutes 2, and the longitudinal section of chute 2 is semicircular structure, the close shell of chute 2
Side inside 1 is provided with opening, and the front end of opening is provided with locking member, and the chute 2 of the left and right sides is corresponding in same level,
Upper isolated area 11, middle isolated area 12 and lower isolated area 13 are equipped with two-sided wiping board 3, and the both sides of two-sided wiping board 3 are provided with and the phase of chute 2
The draw runner 31 of matching, two surfaces up and down of two-sided wiping board 3 are provided with wiper 32, and the outside of two-sided wiping board 3 is provided with otic placode 33.
In the present embodiment, using the wiper 32 to be washed and brush before blackboard eraser on two-sided wiping board 3, every piece of two-side eraser when scrubbing
Plate 3 slides up and down several times in upper division board 14, and the projection 16 on this when of isolated area mouth both sides is while cleaning wiper 32, one side
Extrude wiper 32 and exclude water, keep the dampness of the appropriateness of wiper 32.During using blackboard eraser to erase the board, three pieces of two-sided wiping boards
3 fill in three chutes 2 in isolated area 11, middle isolated area 12 and lower isolated area 13 respectively, are then locked with locking member solid
It is fixed, it is the wiper on the lower surface of nethermost one piece two-sided wiping board 3 when erasing the board, after three pieces of two-sided wiping boards 3 are installed
32 can contact blackboard, and during this face wiper 32 of Reusability, the chalk of mud can adhere to wiper 32, will result in blackboard eraser and obtain not
Totally, at this time we can extract the two-sided wiping board 3 of this part it is turned over and are again introduced into lower isolated area 13, be dirty that
Individual wiper 32 translates into back, and clean another side wiper 32 translates into bottommost, after the clean wiper 32 in this face is also dirty, I
