Abstract

The utility model discloses an electric dust-free teaching blackboard, which comprises a body framework, a magnetic writing board, a magnetic writing pen and an erasing device. The body framework comprises an outer frame and sliding grooves, a pen holder is arranged on the outer frame of the body framework, and the magnetic writing pen is inserted in the pen holder; the magnetic writing board is mounted on the outer frame of the body framework and comprises a writing layer, a magnetic layer and a packaging layer which are sequentially mounted; and the erasing device comprises a slide mechanism, a magnetic erasing layer and an electric transmission mechanism, wherein sliding wheels of the slide mechanism are mounted in the sliding grooves of the body framework, the upper end and the lower end of the magnetic erasing layer are connected with the slide mechanism, the magnetic erasing layer is enabled to be adhered to the back of the packaging layer, and the electric transmission mechanism is connected with the slide mechanism. The electric dust-free teaching blackboard is convenient in mounting and use and low in cost and does not affect the physical health of teachers and students.

Description

Electrodynamic type does not have the dust blackboard for education

Technical field

The utility model relates to a kind of electrodynamic type does not have the dust blackboard for education, and Writing-painting is with the teaching plate when being mainly used in teaching.

Background technology

Blackboard for education is one of the most basic educational aid of teacher's daily teaching, because it is with low cost, uses simple; So in teaching, be in use to now always; But there are a lot of drawbacks in this teaching method, like the dust pollution that chalk brings, badly influences the healthy of teachers and students; The long-term blackboard eraser that uses removes the writing difficulty, makes teacher's writing on the blackboard unintelligible, influences quality of instruction.Along with the progress of modern science and technology, multiple modes such as projection teaching, television teaching, online class are introduced in the teaching, but because the aforesaid way use cost is high; Additional conditions are many; Only be used in the aided education facility, this traditional writing on the blackboard pattern of blackboard for education is not eliminated in the aspectant teaching of teacher; Particularly in small and medium-sized cities, the classroom, rural area remains main teaching equipment; It is thus clear that blackboard for education need have is cheap, easy to use, do not influence functions such as teachers and students' health, but does not appear in the newspapers in the current techniques.

Summary of the invention

The utility model is for addressing the above problem, provide a kind of easy to install, cheap, do not influence the healthy electrodynamic type of teachers and students and do not have the dust blackboard for education.

The utility model is for achieving the above object; The technical scheme of being taked is: electrodynamic type does not have the dust blackboard for education; Comprise body frame, magnetic wordpad, magnetic writing pen, erasing apparatus; Said body frame comprises outer rim and sliding tray, and the outer rim of body frame is provided with the pen holder, and the magnetic writing pen assigns in the pen holder; Said magnetic wordpad is installed on the outer rim of body frame, comprises writing layer, magnetosphere, the encapsulated layer installed successively; Described erasing apparatus comprise slide mechanism, magnetic wipe the layer and electric transmission; The pulley of slide mechanism is installed in the sliding tray of body frame; The two ends up and down that magnetic is wiped layer are connected with slide mechanism, make its back that is attached to encapsulated layer, and electric transmission connects slide mechanism.

The beneficial effect of the utility model is: the magnetic writing pen cooperates with magnetic wordpad; Utilize magnetic that word or pattern are become on the present magnetic wordpad; Pulling erasing apparatus utilizes magnetic with the magnetisable material playback that appears on the magnetic wordpad; Whole device is easy to install, cheap, owing to can not produce the dust pollution that traditional chalk brings, so can not have influence on the healthy of teachers and students, safety and environmental protection.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the front view (partial sectional view) of the utility model;

Fig. 2 is the left view of the utility model.

Among the figure: 1, body frame, 2, magnetic wordpad, 3, the magnetic writing pen, 4, erasing apparatus, 11, outer rim; 12, sliding tray, 13, pen holder, 21, writing layer, 22, magnetosphere, 23, encapsulated layer; 41, slide mechanism, 42, magnetic wipes layer, 43, electric transmission, 44, motor; 45, commutator, 46, travelling gear, 47, stop, 48, start button.

The specific embodiment

There is not the dust blackboard for education like Fig. 1, the electrodynamic type shown in 2; Comprise body frame 1, magnetic wordpad 2, magnetic writing pen 3, erasing apparatus 4; Said body frame 1 comprises outer rim 11 and sliding tray 12; The outer rim 11 of body frame 1 is provided with pen holder 13, and magnetic writing pen 3 assigns in the pen holder 13; Said magnetic wordpad 2 is installed on the outer rim 11 of body frame 1, comprises writing layer 21, magnetosphere 22, the encapsulated layer 23 installed successively; Described erasing apparatus 4 comprises that slide mechanism 41, magnetic wipes layer 42 and electric transmission 43; The pulley of slide mechanism 41 is installed in the sliding tray 12 of body frame 1; The two ends up and down that magnetic is wiped layer 42 are connected with slide mechanism 41; Make its back that is attached to encapsulated layer 23, electric transmission 43 connects slide mechanism 41.

Further, said magnetosphere 22 is a honeycomb structure, and six limit length of sides of the hexahedron of honeycomb structure are 2 millimeters, in honeycomb structure, fills the magnetic that is mixed by kerosene, iron powder, talcum powder.

Further, said electric transmission 43 comprise motor 44, be installed in commutator 45 on the motor 44, be installed in travelling gear 46 on 44 in the motor, be installed in sliding tray 12 two ends stop 47, be installed in the start button 48 of outer rim 11 bottoms.

Drive 41 operations of travelling gear 46 driving slide mechanisms when pressing start button 48 by motor 44; From a lateral movement to opposite side, after slide mechanism 41 touches the stop 47 that sliding tray 12 1 sides install, stop motion; Commutator 45 actions; Next time, motor 44 reverse rotations realized the purpose of wiping automatically when pressing start button 48.
