Abstract
The utility model discloses a special blackboard for handwriting exercise, comprising a blackboard frame and a blackboard board, wherein the blackboard board is installed in the blackboard frame, used for writing and formed by splicing a plurality of rotatable triangular prisms, and a speed reducing motor for driving the triangular prisms to rotate is fixed on the blackboard frame. For the blackboard, the blackboard board does not adopt the original fixed mode, and is formed by splicing the plurality of triangular prisms, so that when the blackboard board is full of characters by writing, the triangular prisms are rotated to form a new blackboard board so as to be written continuously, and repeatedly, three blackboard boards can be formed, so that a user can write on the boards.
Description
Technical field:
The utility model relates to a kind of teaching aid, relates to a kind of special blackboard of practising handwriting in particular.
Background technology:
Blackboard is a kind of realia indispensable in the classroom, it generally is made of frame and plate face, the plate face is used for writing, existing blackboard panel is fixed, can write again after after it writes full word, needing to wipe clean with blackboard eraser, but so just relatively lose time, especially exercise writes with chalk word on blackboard when, all the more so.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of special blackboard of practising handwriting is provided, and the plate face of its blackboard can temporarily not need to wipe after having write word, is directly changed into new plate face and continues to write.
Technology solution of the present utility model is as follows:
The special blackboard of practising handwriting, comprise blackboard framework, be installed in blackboard panel in the blackboard framework, that be used for writing, described blackboard panel is spliced by a plurality of rotating regular triangular prisms, is fixed with one on the described blackboard framework and drives the decelerator that described regular triangular prism rotates.
The described special blackboard of practising handwriting, the two ends up and down of described each regular triangular prism have the upper and lower side axle, described upper and lower side axle is hingedly mounted in the upper and lower side frame of described blackboard framework, on each upper shaft or lower end axle, be fixed with a driven gear, be fixed with a driving gear on the described decelerator, described driving gear is connected with described driven gear by chain.
The described special blackboard of practising handwriting, described decelerator is made of motor and reductor, and described driving gear is fixed on the output shaft of described reductor.
The described special blackboard of practising handwriting, described motor is connected with the single-chip microcomputer of its rotation of control, also is connected with a gauge tap on this single-chip microcomputer.
The described special blackboard of practising handwriting, described gauge tap is installed on the described blackboard framework.The utility model beneficial effect is:
The blackboard that this is novel, the plate face of its blackboard are not fixing in the past forms, but are spliced by a plurality of regular triangular prisms, after the plate face is write full word, make regular triangular prism rotate like this, form a new plate face and can continue to write, so repeatedly, can form 3 plate faces writes for the user.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this novel structural representation.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment, see accompanying drawing 1, the special blackboard of practising handwriting, comprise blackboard framework 1, be installed in the blackboard framework, the blackboard panel 2 that is used for writing, blackboard framework is by four rectangular box that frame is linked in sequence and fixedly forms up and down, it has constituted the main supporting body of blackboard, this frame also is to be used for fixing on the wall, generally be to have a groove on the wall, square frame is embedded in this groove, described blackboard panel is spliced by a plurality of rotating regular triangular prisms 201, is fixed with one on the described blackboard framework and drives the decelerator 3 that described regular triangular prism rotates.
The two ends up and down of described each regular triangular prism have upper and lower side axle 201a, 201b, described upper and lower side axle is hingedly mounted in the upper and lower side frame 101,102 of described blackboard framework, on each upper shaft or lower end axle, be fixed with a driven gear 4, be fixed with a driving gear 5 on the described decelerator, described driving gear is connected with described driven gear by chain 6.Like this, just can under the drive of driving gear, realize the rotation of regular triangular prism, after having write word, 60 ° of regular triangular prism rotations just can form a new blackboard panel, convenience very makes the plate face of whole blackboard temporarily not need cleaning, and helps improving the efficient of teaching, handwriting practicing.
Described decelerator 3 is made of motor 301 and reductor 301, and described driving gear is fixed on the output shaft of described reductor.Motor is used to provide the power of rotation, because the rotating ratio of motor is higher, high like this rotating speed is not that we are desired and use, so be reduced in the scope that needs by the rotating speed of reductor with motor, make it can drive regular triangular prism and rotates stably.
Described motor is connected with the single-chip microcomputer 7 of its rotation of control, also is connected with a gauge tap 8 on this single-chip microcomputer.
Described gauge tap is installed on the described blackboard framework.
