Abstract
The utility model relates to a kind of blackboard with dark ruling, comprise blackboard body, it is characterized in that, in described blackboard body, along continuous straight runs is evenly equipped with light hole, described light hole is forming optically focused seam near blackboard surface, also comprise the illumination box that is arranged on described blackboard body one side, in described illumination box, be provided with LED installing plate, on described LED installing plate, be evenly equipped with LED spotlight, the front end of described LED spotlight puts in described light hole, described light hole is in the opposite side sealing of blackboard body, described LED installing plate connects power control box, the beneficial effects of the utility model are, while needs, can on blackboard, demonstrate fast parallel lines, save teacher's setting-out time, alleviate teacher's working strength.
Description
Technical field
The utility model relates to teaching field, relates in particular to a kind of blackboard with dark ruling.
Background technology
Although adopted in a large number the multimedia facility that can fast show, contain much information in modern teaching, can traditional blackboard is still requisite instrument in daily teaching.But the deficiency of traditional blackboard is, when need writing on the blackboard parallel lines or English teaching to use four rulings time, write picture by hand and relatively lose time, if can fast processing, effect can be better.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provides a kind of blackboard that can demonstrate when needed the dark ruling of band of parallel lines on blackboard.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of blackboard with dark ruling, comprise blackboard body, it is characterized in that, in described blackboard body, along continuous straight runs is evenly equipped with light hole, described light hole is forming optically focused seam near blackboard surface, also comprise the illumination box that is arranged on described blackboard body one side, in described illumination box, be provided with LED installing plate, on described LED installing plate, be evenly equipped with LED spotlight, the front end of described LED spotlight puts in described light hole, described light hole is in the opposite side sealing of blackboard body, described LED installing plate connects power control box, described power control box is provided with switch.
The beneficial effects of the utility model are that the light by LED spotlight in light hole shows, has replaced teacher's setting-out operation.In the time not needing lines to show, closing switch, use the same with normal blackboard.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described blackboard body comprises base plate and is located at the panel on described base plate, and described panel is glass epoxy, and described optically focused seams the inboard at described glass epoxy.
Adopt the beneficial effect of above-mentioned further scheme to be, optically focused seam can make lights crowds demonstrate lines.
Further, described power control box is provided with two switches, and the first switch or second switch are closed respectively, and adjacent described LED spotlight is bright, and the first switch and second switch are simultaneously closed, and whole described LED spotlights are bright.
The beneficial effects of the utility model are can selectively show lines as required like this.
The beneficial effects of the utility model are that, in the time that the content of courses need to draw parallel lines or four lattice three lines, by the cooperation of LED spotlight and light hole, energy show required parallel lines fast on blackboard, has alleviated teacher's working strength.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Figure 1A-A is to cutaway view;
Fig. 3 is circuit diagram of the present utility model.
At Fig. 1 in Fig. 3,1, black body; 1-1, panel; 1-2, base plate; 2, light hole; 3, LED spotlight; 4, LED installing plate; 5, optically focused seam; 6, power control box; K1, the first switch; K2, second switch.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, 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 with dark ruling, comprise blackboard body 1, in described blackboard body, along continuous straight runs is evenly equipped with light hole 2, described light hole 2 is forming optically focused seam 5 near blackboard surface, also comprise the illumination box that is arranged on described blackboard body 1 one sides, in described illumination box, be provided with LED installing plate 4, on described LED installing plate 4, be evenly equipped with LED spotlight 3, the front end of described LED spotlight puts in described light hole 2, described light hole 2 is in the opposite side sealing of blackboard body, described LED installing plate 4 connects power control box 6, described power control box 6 is provided with switch.
Described blackboard body 1 comprises base plate 1-2 and is located at the panel 1-1 on described base plate, and described panel 1-1 is glass epoxy, and described optically focused seam 5 is located at the inboard of described glass epoxy.Described optically focused seam 5 also can run through glass epoxy, stitches 5 places be provided with filler at described optically focused, and described filler is semi-transparent resin material, and in the time that LED spotlight is bright, what see is bright parallel lines like this.After writing, can turn off power switch, parallel lines disappear, and can not affect and watch blackboard.
Described power control box 6 is provided with two switches, and the first K switch 1 or second switch K2 are closed respectively, and bright 3, the first K switch 1 of adjacent LED spotlight are simultaneously closed with second switch K2, and whole described LED spotlights 3 are bright.
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 of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
