Description
Technical field
The utility model relates to teaching aid field, particularly relates to a kind of blackboard.
Background technology
The blackboard used in usual teaching, generally only comprises plate body, but in English, music and phonetic teaching, teacher often will draw parallel ruling, and as four line three rulings, freehand drawing can be lost time, and sometimes also draws not straight.Also there are some auxiliary line-plotting devices, the inconvenience of installing or using can be there is.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of blackboard, can mark four line lattice or parallel lines as required easily.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of blackboard, comprise blackboard body, it is characterized in that, also comprise and be vertically fixed on the described slideway base on the blackboard body left side and the lath on the right respectively, described slideway base and lath are ferromagnetic, described slideway base comprises base plate, described base plate is provided with slideway, described slideway is provided with tape measure seat, the bottom of described tape measure seat is provided with the chute suitable with described slideway, equidistantly on described tape measure seat be fixed with four tape measures, each described tape measure draw chi head parallel be fixed on a magnetic plate, described magnetic plate is adsorbed on described base plate, described magnetic plate is also provided with handle.
The beneficial effects of the utility model are, when needing setting-out, as long as utilize handle to pull magnetic plate four tape measures to extend to the right simultaneously, are then adsorbed on by described magnetic plate on the described lath in right side, above tape measure, just can carry out setting-out quickly and easily.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described slideway is swallow-tail form slideway, and described tape measure seat is also provided with lock(ing) bolt.
Adopt the beneficial effect of above-mentioned further scheme to be that dovetail type slideway moves unobstructed, lock(ing) bolt can play fixation.
Further, on board and batten of the described end, also correspondence is provided with rule.
The beneficial effect of above-mentioned further scheme is adopted to be, by rule, can ensure that shift position is more accurate in the horizontal direction.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1 to Figure 3, a kind of blackboard, comprise blackboard body 10, also comprise and be vertically fixed on the slideway base on the described blackboard body left side and the lath 7 on the right respectively, described slideway base and lath are ferromagnetic, described slideway base comprises base plate 1, described base plate is provided with slideway 2, described slideway is provided with tape measure seat 4, the bottom of described tape measure seat is provided with the chute suitable with described slideway, equidistantly on described tape measure seat be fixed with four tape measures 5, each described tape measure draw chi head parallel be fixed on a magnetic plate 3, described magnetic plate is adsorbed on described base plate, described magnetic plate is also provided with handle 6.
Described slideway 2 is swallow-tail form slideway, and described tape measure seat 4 is also provided with lock(ing) bolt 8.
On board and batten of the described end, also correspondence is provided with rule 9.
The utility model uses like this, when ruling, catch hold of handle 6 with hand to move right, article four, tape measure 5 just can be hauled out to the right of blackboard simultaneously, being inhaled by described magnetic plate 3 is attached on described lath 7, just can setting-out above each tape measure, by moving up and down described tape measure seat, more four line lattice can also be drawn.After tape measure seat 4 moves into place, be also fixed by lock(ing) bolt.Due to magnetic effect, what magnetic plate can be very stable is adsorbed on lath 7, and at the end of line, then regained by tape measure by handle, tape measure spring force close to the inner portion can indentation easily.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
