Described sponge is two, and it is symmetricly set on the left and right sides of blackboard eraser, and the back side of described blackboard eraser is symmetrical to be provided with for the fixing groove of sponge.
The front end of described base plate and top board stretches out plate body certain distance, and correspondence is provided with chute on base plate and top board, and the two ends up and down of blackboard eraser are respectively equipped with pulley.
Between described pulley and blackboard eraser body, by dwang, be connected, the two ends of described dwang are rotationally connected with both respectively.
Described blackboard eraser top and bottom are respectively equipped with two pulleys, and two pulleys of upper end or lower end link into an integrated entity by connecting rod respectively, on described connecting rod, are rotatably connected to dwang.
The outer surface of described blackboard eraser is also provided with plate body.
Described right plate is provided with the gauge tap being electrically connected to lighting apparatus.
Adopt after said structure, the plate body of blackboard is used blank, there is not mirror-reflection in blank, substantially there is not irreflexive situation in the word of writing on plate body, effectively solve the problem not seeing, improve learning efficiency, by lighting apparatus is installed at plate body rear portion, improve brightness, external high light major part is absorbed, and effectively reduces mirror-reflection.In plate body front side, be provided with the blackboard eraser that plate body slides relatively simultaneously, raising wiping efficiency, and produce the problem of powder while having solved blackboard wiping, be conducive to the healthy of teacher.
Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Fig. 1 is along the cutaway view of A-A line.
The specific embodiment
As shown in figure and Fig. 2, blackboard comprises plate body 1, the rear portion of plate body 1 is provided with by base plate 2, top board 3, left plate 5, the closed box that right plate 4 and backboard 6 form, base plate 2, left plate 5, right plate 4 and backboard 6 are made by opaque material, opaque material can be selected plank or metal material, also the prefabricated closed box in blackboard place can be directly installed in classroom, lighting apparatus 7 is installed in closed box, in the present embodiment, lighting apparatus 7 is three incandescent lamp tubes, three incandescent lamp tubes are between the upper and lower every setting, on left side plate inwall, be respectively equipped with for the tube face 8 of incandescent lamp tube is installed, right plate 4 is provided with the gauge tap 17 being electrically connected to incandescent lamp tube, each root incandescent lamp tube is controlled by a gauge tap 17, can better regulate the brightness of closed box like this.For better improving brightness, can on the inwall of backboard 6, reflective membrane be set.
The translucent plate body that in the utility model, plate body 1 is smooth outer surface, plate body 1 is selected blank, and blank can be selected blank on sale on the market, also can make blank by the inner surface plating white coating at glass.
The front side of plate body 1 is provided with the blackboard eraser 9 that plate body 1 slides relatively, the back side of blackboard eraser 9 is provided with the sponge 10 that can contact with plate body 1 outer surface, sponge 10 is along blackboard eraser 9 short transverse settings, sponge 10 is two, it is symmetricly set on the left and right sides of blackboard eraser 9, and the back side of blackboard eraser 9 is symmetrical to be provided with for the fixing groove of sponge 10, and sponge 10 is arranged in groove, in the time of can preventing from erasing the board, sponge 10 stress deformations affect wiping effect.
The relative sliding of blackboard eraser 9 can be realized by following structure: the front end of base plate 2 and top board 3 stretches out plate body 1 certain distance, and on base plate 2 and top board 3 along its length upper and lower correspondence be provided with chute 11, blackboard eraser 9 top and bottom are respectively equipped with two pulleys 12, for the uniformity that guarantees that upper end or two of lower ends pulley 12 move, two pulleys 12 of upper end or lower end link into an integrated entity by connecting rod 13 respectively, connecting rod 13 is provided with overhanging upper joint pin 15, on upper joint pin 15, be rotatably connected to horizontally disposed dwang 14, by being set in upper joint pin 15 ends, bolt 16 realizes itself and being connected of dwang 14, the other end of dwang 14 is rotatably connected on the lower joint pin 18 of blackboard eraser 9 ends settings, thereby realize being connected of pulley 12 and blackboard eraser 9, shown in Fig. 2, dwang 14 is perpendicular to the surface of plate body 1, now sponge 10 keeps at a certain distance away with the outer surface of plate body 1, thereby guarantee that blackboard eraser 9 moves left and right Shi Buhui the word of writing on plate body 1 is wiped.While needing blackboard wiping, promote blackboard eraser 9 dwang 14 is rotated, make sponge 10 be close to plate body 1 surface, realize the wiping of blackboard.In the utility model, chute 11 also can design separately, after designing, it is directly bound on top board 3 and base plate 2, and this kind of structure can reduce the manufacturing cost of base plate 2 and top board 3, reduces the cost of manufacture of blackboard.For better utilizing blackboard eraser 9, at the outer surface of blackboard eraser 9, be also provided with plate body 1, the utility model just has small one and large one two boards body 1 to write like this, is more conducive to teacher's teaching.
