Abstract
A kind of dustproof blackboard eraser suitable for ideology and politics teaching.In the teaching process of ideology and politics, since theoretical property is stronger, teacher often writes a large amount of word to impart knowledge to students, when blackboard writes language of the Manchus word on blackboard, it is necessary to which blackboard eraser is wiped, and is then being write.A kind of dustproof blackboard eraser suitable for ideology and politics teaching, composition include：Left side clamping plate（1）With right side clamping plate（2）, otic placode is provided with above left side clamping plate and right side clamping plate（3）, otic placode by shaft respectively with down-pressed pole one（4）With down-pressed pole two（5）Connection, the end projective structure of down-pressed pole one pass through fixed rotating shaft（6）It is inserted in the concave structure of down-pressed pole two, the projective structure of left side clamping plate is inserted in by fixed rotating shaft in the concave structure of right side clamping plate, and the high-tension sponge of rectangular configuration is placed with below left side clamping plate and right side clamping plate（7）.The utility model is applied to the dustproof blackboard eraser of ideology and politics teaching.
Description
Technical field：
The utility model is related to a kind of dustproof blackboard erasers suitable for ideology and politics teaching.
Background technology：
In the teaching process of ideology and politics, since theoretical property is stronger, teacher often writes on blackboard a large amount of
Word is imparted knowledge to students, when blackboard writes language of the Manchus word, it is necessary to which blackboard eraser is wiped, and is then being write.Traditional religion
Tool（Blackboard, chalk）Cheaply and conveniently, so there is many school classrooms still using blackboard and chalk now,
In order to avoid chalk ash pollution teaching environment and prevent chalk dust from endangering the health of teachers and students in wiping process, to powder
In the grey wiping process of pen, the towel for often using adhesional wetting is wiped, and can prevent chalk dust from being flown upward in classroom in this way, when
Often towel is rinsed when blackboard wiping in this way, can also continue to make by towel twisting after flushing
With, not only waste time, it is also not high to the service efficiency of wet towel, simultaneously because skin contacts for a long time with wet towel, to skin
Skin will also result in certain influence.
Invention content：
The purpose of this utility model is to provide a kind of dustproof blackboard eraser suitable for ideology and politics teaching.
Above-mentioned purpose is realized by following technical scheme：
A kind of dustproof blackboard eraser suitable for ideology and politics teaching, composition include：Left side clamping plate and right side clamping plate, it is described
Left side clamping plate and the right side clamping plate above be provided with otic placode, the otic placode by shaft respectively with down-pressed pole one and
Down-pressed pole two connects, and the end projective structure of the down-pressed pole one is inserted in the recessed of the down-pressed pole two by fixed rotating shaft
In type structure, the projective structure of the left side clamping plate is inserted in the concave structure of the right side clamping plate by fixed rotating shaft
It is interior, the high-tension sponge of rectangular configuration is placed with below the left side clamping plate and the right side clamping plate.
The dustproof blackboard eraser suitable for ideology and politics teaching, the down-pressed pole one and the down-pressed pole two
Arcwall face is machined on pole face.
The dustproof blackboard eraser suitable for ideology and politics teaching, the left side clamping plate and the right side clamping plate
Side uniformly offers one group of threaded hole, the threaded hole interior column type part or bolt inserted with threaded structure.
The beneficial effects of the utility model：
1. when the utility model is used, the high-tension sponge that size in advance has been trimmed is placed into left side clamping plate and right side
In the slot of the lower section of clamping plate, high-tension sponge slides out of slot in order to prevent, can be arranged on left side clamping plate and right side clamping plate
Threaded hole insert in be inserted into screw element, so that high-tension sponge is preferably fixed in slot, when need to high-tension sponge clean
When, two hold the arcwall face stayed on compression bar, and then inside firmly pushes, and down-pressed pole one and down-pressed pole two are turned by fixed rotating shaft
It is dynamic, by otic placode and left side clamping plate and right side clamping plate is driven equally firmly to push inwardly, is squeezed during pushing and be placed on folder
High-tension sponge in board slot squeezes out the moisture after being cleaned in sponge.
The utility model is simple in structure, easy to operate, after complete to blackboard-cleaning, need not take out high-tension sponge,
It can be used continuously as long as high-tension sponge is washed with water, when squeezing the moisture in high-tension sponge, under
Compression bar drives clamping plate can be completed and squeezes out the moisture in sponge, has saved the time, has improved work efficiency, while can also prevent
Only skin is directly contacted with the dirty water after cleaning.
Description of the drawings：
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the vertical view of attached drawing 1.
In figure：1, left side clamping plate, 2, right side clamping plate, 3, otic placode, 4, down-pressed pole one, 5, down-pressed pole two, 6, fixed rotating shaft, 7,
High-tension sponge, 8, threaded hole.
Specific implementation mode：
Embodiment 1：
A kind of dustproof blackboard eraser suitable for ideology and politics teaching, composition include：Left side clamping plate 1 and right side clamping plate 2, institute
Be provided with otic placode 3 above the left side clamping plate and the right side clamping plate stated, the otic placode by shaft respectively with down-pressed pole
1 and down-pressed pole 25 connect, the end projective structure of the down-pressed pole one is inserted in the pushing by fixed rotating shaft 6
In the concave structure of bar two, the projective structure of the left side clamping plate is inserted in the recessed of the right side clamping plate by fixed rotating shaft
In type structure, the high-tension sponge 7 of rectangular configuration is placed with below the left side clamping plate and the right side clamping plate.
Embodiment 2：
According to the dustproof blackboard eraser described in embodiment 1 suitable for ideology and politics teaching, the down-pressed pole one and described
Down-pressed pole two pole face on be machined with arcwall face.
Embodiment 3：
