Abstract

The invention discloses a hand-pull-type dust-free teaching blackboard which comprises a body frame, a magnetic writing board, a magnetic writing pen and an erasing device, wherein the body frame comprises an outer frame and a sliding chute, a pen holder is arranged on the outer frame of the body frame, and the magnetic writing pen is inserted in the pen holder; the magnetic writing board is mounted on the outer frame of the body frame and comprises a writing layer, a magnetic layer and a packaging layer, which are arranged in sequence; the erasing device comprises a sliding mechanism, a magnetic erasing layer and pull ropes; the pulley of the sliding mechanism is arranged in the sliding chute of the body frame; and the upper and the lower ends of the magnetic erasing layer are connected with the sliding mechanism such that the magnetic erasing layer is attached behind the packaging layer, and the left and the right sides of the magnetic erasing layer are connected with the pull ropes. The hand-pull-type dust-free teaching blackboard is convenient for installation and use, has a low price and does not affect physical health of teachers and students.

Description

Hand pulling type does not have the dust blackboard for education
Technical field
The present invention relates to a kind of hand pulling 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 present invention is for addressing the above problem, provide a kind of easy to install, cheap, do not influence the healthy hand pulling type of teachers and students and do not have the dust blackboard for education.
The present invention is for achieving the above object; The technical scheme of being taked is: hand pulling 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 stay cord; 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 the right and left is connected with stay cord.
The invention has the beneficial effects as follows: 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 present invention is further specified.
Fig. 1 is front view of the present invention (partial sectional view);
Fig. 2 is a left view of the present invention.
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, stay cord.
The specific embodiment
There is not the dust blackboard for education like Fig. 1, a kind of hand pulling 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 stay cord 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, the right and left is connected with stay cord 43.
Further; Said magnetosphere 22 is a honeycomb structure; Six limit length of sides of the hexahedron of honeycomb structure are 2 millimeters, in honeycomb structure, fill the magnetic that is mixed by kerosene, iron powder, talcum powder, and kerosene, iron powder, talcous mixed proportion are 6: 3: 1 in the said magnetic.
Only need take magnetic writing pen 3 on writing layer 21, directly to write during use; Magnetic receives 3 attractions of magnetic writing pen and is presented on the writing layer 21; Write end, in the time of need wiping, only need pulling stay cord 43; Move to the other end from an end, magnetic is attracted back honeycomb and wipes handwriting and make magnetic wipe layer 42.
