Description

A kind of blackboard

Technical field

The utility model relates to a kind of teaching aid, is specifically related to a kind of blackboard.

Background technology

As everyone knows, blackboard is used in school with aid widely as a kind of teaching, and teacher writes on blackboard by using chalk, carries out various education activities.

At present, the blackboard that generally uses in school generally all is a plate that ganoid stiff materials is made, its surperficial painted black, and be fixed on the wall in the classroom.Teacher utilizes chalk to write on the blackboard surface at school the time, carries out education activities.Yet there is a bigger deficiency in use in this class blackboard, blackboard is to be fixed on the indoor wall, not removable, be a teacher and bookish data need be copied when writing on the blackboard, generally all be to adopt a hand-held book, the mode that proficiency holds a pen, move by side to opposite side from one of blackboard and write, still, such mode of operation needs teacher's two hands to hold book simultaneously respectively to hold a pen, inconvenience has in the extreme greatly increased the labour intensity that teacher imparts knowledge to students.

Summary of the invention

The utility model purpose provides a kind of blackboard, by the improvement to structure, has reduced the labour intensity of teacher's teaching.

For achieving the above object, the technical solution adopted in the utility model is: a kind of blackboard, comprise a blackboard body, and the vertical bookshelf that is provided with described blackboard body, described bookshelf is connected with described blackboard body downside through slide construction.

Further technical scheme, described blackboard body downside offers chute, is engaged in described bookshelf with described chute and is provided with slide block, constitutes described being slidingly connected.

Above, teacher in class, in the time of need copying bookish data to blackboard, earlier books are positioned on the bookshelf that is connected with the blackboard downside, teacher just can bow and see books this moment, and then data copied write on the blackboard, needing to have avoided a hand-held book in the past, copied on the other hand, reduced the labour intensity of teaching, and because being slidingly connected between bookshelf and the blackboard, teacher when one of blackboard moves by side to opposite side, can move bookshelf when copying simultaneously thereupon, conveniently proceeds to copy.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, because the utility model by the vertical bookshelf that is provided with the blackboard body, connects through slide construction, makes books can be positioned on the bookshelf between the two, make things convenient for teacher to teach, reduced the labour intensity of teacher's teaching;

2, be connected through slide construction between bookshelf of the present utility model and the blackboard body, thereby make bookshelf to move relative to blackboard, made things convenient for teaching along with moving of teacher position;

3, because bookshelf of the present utility model is sliding, can move when erasing the board, thereby chalk dust lodges in problem on the bookshelf when avoiding adopting the bookshelf of stationary structure;

4, the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is an A-A place cutaway view among Fig. 1.

Wherein: 1, blackboard body; 2, bookshelf; 3, slide block.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: shown in Fig. 1,2, a kind of blackboard, comprise a blackboard body 1, with the described blackboard body 1 vertical bookshelf 2 that is provided with, described blackboard body 1 downside offers chute, be engaged in described bookshelf 2 with described chute and be provided with slide block 3, be slidingly connected between described bookshelf 2 and the blackboard body 1.

Teacher is in teaching, teacher in the time of need copying bookish data to blackboard, can earlier books be positioned on the bookshelf 2, on one side can read a book then, on one side data is copied to blackboard, impart knowledge to students, need not to hold a pen as a hand-held book in the past, on the other hand and copy, thereby reduced the labour intensity of teaching, simultaneously owing to be slidingly connected between bookshelf 2 and the blackboard, be a teacher when blackboard one moves by side to opposite side, bookshelf 2 also can be thereupon from blackboard one opposite side that breaks away, made things convenient for teaching.

Claims (2)

1. a blackboard comprises a blackboard body (1), it is characterized in that: the vertical bookshelf (2) that is provided with described blackboard body (2), described bookshelf (2) is connected with described blackboard body (1) downside through slide construction.

2. a kind of blackboard according to claim 1 is characterized in that: described blackboard body (1) downside offers chute, is engaged in described bookshelf (2) with described chute and is provided with slide block (3), constitutes described slide construction.
