Abstract
The utility model relates to a teaching aid, in particular to novel belt type blackboard that prevents dust. Mainly constitute characterized by by gear reducer motor, belt pulley, belt, drive belt blackboard face, control circuit, brush, axis of rotation, backup pad, blackboard backplate: both ends about the blackboard are settled to the axis of rotation, and the backup pad is fixed in between two axis of rotation, blackboard face is endless conveyor formula face, and blackboard face is supported by axis of rotation and backup pad jointly, in the time of need cleaning blackboard face, through the rotation of control circuit control motor, can drive blackboard face indirectly and rotate, makes blackboard face cleaned by the brush of blackboard backplate. Therefore, the beneficial effects of the utility model are that: this novel belt type blackboard that prevents dust, simple structure, convenient and practical while can use and clean, has enlarged the usable floor area of blackboard, and the dust who has avoided artifical and clean the blackboard to cause flies upward, and the influence is healthy, improves the teaching efficiency and quality.
Description
Technical field
This utility model relates to a kind of Novel conveyor-band formula dustproof blackboard, say accurately be one can with auto-erasing and can in case
Only the blackboard of chalk ash pollution indoor environment, belongs to realia field.
Background technology
Blackboard is the most common, and traditional blackboard needs manual wipping after writing full word, powder ash can be caused to fly upward, and waste lecture time,
Have a strong impact on teachers ' health and efficiency of attending class.
Utility model content
In order to overcome existing blackboard eraser to fly upward except rear dust, and affect the deficiency of efficiency of attending class, here can be certainly by open one
Dynamic erasing and centralized collection chalk dust, time-consuming, prevent the Novel conveyor-band formula dustproof blackboard that dust pollutes, solve biography
System blackboard is wasted the class period and affects the shortcoming that teacher is healthy.
This utility model solves the technical scheme that its technical problem uses: a kind of Novel conveyor-band formula dustproof blackboard, mainly by gear
Reducing motor (1), belt pulley (2), belt (3), conveyer belt blackboard surface (4), control circuit (5), hairbrush (6), turn
Moving axis (7), controls switch (8), gripper shoe (9), and blackboard backboard (10) forms, it is characterised in that: rotary shaft (7)
Being placed in the upper and lower two ends of blackboard, gripper shoe (9) is fixed between two rotary shafts (7), and conveyer belt blackboard surface (4) is rotated axle
(7) jointly support with gripper shoe (9)；Toothed gearing electric motor (1) is placed in gripper shoe (9) right side central；Belt pulley (2)
One is arranged on toothed gearing electric motor (1) outfan, and it is outside that another is mounted on the rotary shaft (7) above blackboard, and two
Individual belt pulley (2) is connected by belt (3)；Control circuit (5) is placed in blackboard lower right-hand side, toothed gearing electric motor (1)
Control circuit (5) it is connected into respectively with controlling switch (8)；Hairbrush (6) is placed in blackboard backboard (10) above.
Described conveyer belt blackboard surface (4) is the soft material plate face that can write.
The beneficial effects of the utility model are: this utility model is easy to use, can save the class period, improve teaching efficiency,
And the pollution of indoor environment can be avoided, there is preferable actually used value.
This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings.

Detailed description of the invention
In the first embodiment shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4, a kind of Novel conveyor-band formula dustproof blackboard, mainly subtracted by gear
Speed motor (1), belt pulley (2), belt (3), conveyer belt blackboard surface (4), control circuit (5), hairbrush (6), rotate
Axle (7), controls switch (8), gripper shoe (9), and blackboard backboard (10) forms, it is characterised in that: rotary shaft (7) is pacified
Putting at the upper and lower two ends of blackboard, gripper shoe (9) is fixed between two rotary shafts (7), and conveyer belt blackboard surface (4) is rotated axle (7)
Jointly support with gripper shoe (9)；Toothed gearing electric motor (1) is placed in gripper shoe (9) right side central；Belt pulley (2) one
Individual being arranged on toothed gearing electric motor (1) outfan, it is outside that another is mounted on the rotary shaft (7) above blackboard, two
Belt pulley (2) is connected by belt (3)；Control circuit (5) is placed in blackboard lower right-hand side, toothed gearing electric motor (1)
Control circuit (5) it is connected into respectively with controlling switch (8)；Hairbrush (6) is placed in blackboard backboard (10) above.
Described conveyer belt blackboard surface (4) is the soft material plate face that can write.
In the second embodiment shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4, when writing needs erasing on blackboard, open control switch (8),
Control circuit (5) can control toothed gearing electric motor (1) and rotate, and drives belt pulley (2) and rotary shaft (7) to rotate accordingly,
And then conveyer belt blackboard surface (4) can be made to rotate, when the writing in front, plate face turns to the blackboard back side with conveyer belt blackboard surface (4)
Time, can be wiped by multiple hairbrush (6), effect is obvious.
In the 3rd embodiment shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4, a kind of Novel conveyor-band formula dustproof blackboard, can be according to difference
The demand of school, can produce different size, class, has preferable actually used value and promotional value.
Claims (2)
