Sound draws the problem of line lattice cause intricate operation and low efficiency of teaching.
Technical solution is as follows used by the utility model：
A kind of blackboard for language teaching, its surrounding edge are equipped with the frame forward extended out, above and below left border
Upper left bearing and lower-left bearing are fixed with respectively on the inside of two corners, and in downside, scuncheon is fixed with close to the position at middle part
Middle undersetting；A longitudinal lamp stand is rotatably connected between upper left bearing and lower-left bearing, equi-spaced apart is arranged on longitudinal lamp stand
Multiple a wordline laser heads being transversely mounted are shown, are also equipped with longitudinal lamp stand for each a wordline laser head thereon
One single switch button；A horizontal lamp stand is rotatably connected between lower-left bearing and middle undersetting, on horizontal lamp stand
Equi-spaced apart is arranged with multiple longitudinally mounted a wordline laser heads, is also each a wordline laser thereon on horizontal lamp stand
Head is equipped with a single switch button；A rotatable partition rod is also hinged with the inner side of middle undersetting, is separated
The left end of bar is hinged on middle undersetting, and right end is open end；For partition rod using double-deck bonding structure, outer layer is irony
Layer, internal layer is cotton layer, and internal layer fits with blackboard panel；Scuncheon and middle undersetting position opposing upper and lower in upside
Equipped with a magnetic block, the length of partition rod and the height of blackboard match, when partition rod is rotated counterclockwise to vertical state,
The right end of partition rod is formed with magnetic block and is fixed.
The a wordline laser head uses rated voltage as 3V, and power is the feux rouges a wordline laser head of 5mW, and each word
Individually it is powered inside line laser head equipped with battery.
In order to realize more preferable rotational positioning, the longitudinal direction lamp stand both ends are connected to upper left bearing and a left side by damp hinge
Between undersetting, the transverse direction lamp stand both ends are connected between lower-left bearing and middle undersetting also by damp hinge.
In order to realize more preferable support, the right end progress to partition rod is also fixed with the downside frame right corner
The supporting block of rest.
The blackboard of the utility model, can be on blackboard with ray in use, by opening part a wordline laser head
Form draws four line lattice of matts and phonetic, therefore is highly suitable for the Chinese character and phonetic teaching of Chinese language, and teachers need not
Effectively improved time-consuming and laboriously with ruler and chalk come setting-out repeatedly, work efficiency.Additionally by partition rod is manipulated, may be used also
Blackboard is separated into two regions in left and right, the left side is electronics setting-out area, and the right is conventional writing on the blackboard area, and the left side is used to demonstrate Chinese character
And phonetic, the right are used for grapho-analysis comment, teaching board distribution is more reasonable, and teaching efficiency is also more preferably.
