Abstract
The utility model relates to a teaching board for an English open class, and mainly solves the problems that the traditional teaching board has a small board surface space and no auxiliary light source. The teaching board is characterized in that a weight-bearing rack (4) is of a telescopic structure and is positioned by a tightening bolt (5), and the lower parts of the two sides of the weight-bearing rack (4) are connected with circular bottom discs (6); the centers of an upper single-body plate (1) and a lower single-body plate (2) are provided with through holes through which a mandrel (3) penetrates, and bearings matched with the mandrel (3) are fixedly arranged in the through holes; the two ends of the mandrel are connected with telescopic rods of the weight-bearing rack (4), and ribs (7) are respectively arranged at the upper and lower ends of surfaces of the upper single-body body (1); and grooves (8) are respectively arranged at the upper and lower ends of the two surface of the lower single-body plate (2), and the ribs (7) are matched with the grooves (8). The teaching board for the English open class is matched with an auxiliary light source of LED (Light Emitting Diode) lighting lamps, the height of the weight-bearing rack is adjusted, the board surface space is large, and the teaching board has practicality.
Description
Technical field
The utility model relates to a kind of teaching appurtenance, specifically, relates to the teaching board that a kind of open class of speaking English is used.
Background technology
In process of English teaching, the knowledge point that the teacher generally wants writing on the blackboard much will say, when particularly saying open class, the English Instructor will be in advance with the new term that will say, new word and grammer writing on the blackboard on blackboard, if limit teaching side plate book, tend to omit a lot of knowledge points and can waste a lot of teaching times in the process of giving lessons, but traditional blackboard panel limited space, constantly wipe writing on the blackboard again and tend to cause dust from flying, the unfavorable health of contaminated environment.
Summary of the invention
The prior art problem that proposes in order to solve background technology, the utility model provides a kind of English open class teaching board, this mount board space of planes is large, the teacher can be in advance with the key content writing on the blackboard that will say on blackboard, blackboard is turning, when evening, use or light were dark, can open the LED illuminating lamp that arranges on the lamp bracket of top, have practicality.
The technical solution of the utility model is: this kind English open class teaching board, comprise monomer plate and lower monomer plate and bearing frame, its unique distinction is: described bearing frame is telescopic structure, locates by fastening bolt, and the bearing frame down either side is connected with circular chassis; The center of described upper monomer plate and lower monomer plate all has the through hole that passes for axle, is fixed with the bearing that is complementary with axle in through hole; The two ends of described axle are connected on the expansion link of bearing frame; The panel upper/lower terminal of described upper monomer plate is respectively equipped with fin, and two panel upper/lower terminals of described lower monomer plate are respectively equipped with groove, and described fin matches with groove.
In addition, at night or light when dark, make a lot of students not see word on blackboard for fear of the light of indoor illumination is reflective, the lamp frame of described bearing frame top connecting band LED illuminating lamp, be the astigmatism plate that has N circular loophole in the lower end of described lamp frame, described LED illuminating lamp is arranged in circular loophole.
The utlity model has following beneficial effect: this kind English open class teaching board, can regulate as required bearing frame and adjust the blackboard height, be provided with the LED illuminating lamp, can avoid at night or light when dark the reflective student of making of indoor light do not see word on blackboard, two blackboards all can facilitate teachers' instruction along the axle upset, the plate space of planes is enough, the teacher can shift to an earlier date writing on the blackboard, can save the teaching time, simultaneously, also having avoided repeatedly, the wiping board book causes dust from flying and unfavorable health.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The upper monomer plate of 1-in figure, monomer plate under 2-, 3-axle, 4-bearing frame, 5-fastening bolt, 6-chassis, 7-fin, 8-groove, 9-LED illuminating lamp, 10-lamp frame, the circular loophole of 11-, 12-astigmatism plate.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind English open class teaching board comprises monomer plate 1 and lower monomer plate 2 and bearing frame 4, and described bearing frame 4 is telescopic structure, and by fastening bolt 5 location, bearing frame 4 down either side are connected with circular chassis 6; The center of described upper monomer plate 1 and lower monomer plate 2 all has the through hole that passes for axle 3, is fixed with the bearing that is complementary with axle 3 in through hole; The two ends of described axle are connected on the expansion link of bearing frame 4; The panel upper/lower terminal of described upper monomer plate 1 is respectively equipped with fin 7, and two panel upper/lower terminals of described lower monomer plate 2 are respectively equipped with groove 8, and described fin 7 matches with groove 8.
In addition, can also further improve on above scheme basis, the lamp frame 10 of described bearing frame 4 top connecting band LED illuminating lamps 9 is the astigmatism plate 12 that has N circular loophole 11 in the lower end of described lamp frame 10, and described LED illuminating lamp 9 is arranged in circular loophole 11.
During use, can regulate as required the bearing frame height, locate by screwing in fastening bolt after mixing up, two panels that consist of blackboard can slide up and down in chute, blackboard can overturn by 360 degree along axle, the fin of top blackboard matches with groove on the blackboard of bottom, prevents that blackboard from rotating on axle.The teacher can use flexibly, this mount board space of planes is large, the teacher before the class with writings on the blackboard such as the knowledge point that will say or exercises on blackboard, at night or light when dark, can open radiationless and LED illuminating lamp stroboscopic action, light is vertically impinging upon on the plate face under the effect of circular loophole.
This kind of English open class teaching board through after experimental application, is proved to be this device and has good practicality, and simple in structure, easy to use, the plate space of planes is large, has been equipped with secondary light source, has saved the middle writing on the blackboard time of giving lessons, and has improved efficiency of teaching.
