Abstract
The utility model relates to a rotating blackboard for a multimedia classroom. The rotating blackboard comprises two slide rails (1) which are horizontally arranged on the wall in parallel, wherein an inner shaft (2) is vertically connected between the two slide rails (1), and a rotating shaft (3) sleeves the inner shaft (2) through a bearing; the back of the middle of a backboard body (5) is fixedly arranged on the rotating shaft (3), and two retaining rods (4) travel between the slide rails (1) and are respectively positioned at the left and right sides of the rotating shaft (3). The rotating blackboard for the multimedia classroom provided by the utility model can effectively reduce the reflection phenomenon of the blackboard.
Description
Technical field
The utility model relates to a kind of Revolving blackboard for multi-media classroom.
Background technology
At present, in large-scale indoor class hours of saying such as multimedias, because student is far away apart from blackboard, in the situation that having light reflection, tend to cause the classmate on left side or right side cannot see the writing on the blackboard on blackboard clearly, thereby affect teacher's the effect of giving lessons.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of multi-media classroom Revolving blackboard that can effectively reduce blackboard reflective light phenomenon is provided.
The purpose of this utility model is achieved in that a kind of multi-media classroom Revolving blackboard, described Revolving blackboard includes two horizontal parallel and is installed on the slide rail on metope, between two one slide rails, connect and be vertically connected with an interior axle, on this interior axle, by bearing holder (housing, cover), one rotating shaft is housed, the back side, middle part of blackboard body is fixed in this rotating shaft.
The utility model multi-media classroom Revolving blackboard, between described slide rail, walking has two levers, and two levers lay respectively at the both sides, left and right of rotating shaft.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can carry out Sloped rotating to blackboard, thereby in the time that generation is reflective, can avoid reflective generation by rotation, makes the student in the large-scale teachers such as multimedia all can see the writing on the blackboard on blackboard clearly, has improved teacher's teaching effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model multi-media classroom Revolving blackboard.
Wherein:
Slide rail 1, interior axle 2, rotating shaft 3, lever 4, blackboard body 5.
Detailed description of the invention
Referring to Fig. 1, a kind of multi-media classroom Revolving blackboard that the utility model relates to, described Revolving blackboard includes two horizontal parallel and is installed on the slide rail 1 on metope, between two one slide rails 1, connect and be vertically connected with an interior axle 2, on this interior axle 2, by bearing holder (housing, cover), one rotating shaft 3 is housed, the back side, middle part of blackboard body 5 is fixed in this rotating shaft 3; Thereby make in use, can make blackboard body 5 rotate to the left or to the right inclination, effectively avoided the generation of reflective phenomenon;
Simultaneously, in order to make to increase the stability of blackboard body 5 in the time writing, between above-mentioned slide rail 1, walking has two levers 4, be that lever 4 upper end ends are slidably connected on superposed slide rail 1, lower end is slidably connected on the slide rail 1 that is positioned at bottom, and two levers 4 lay respectively at the both sides, left and right of rotating shaft 3, thereby make in the time writing, lever 4 can provide support power, prevent that teacher from sliding in the time writing, in the time that needs tilt backboard body 5, only need by lever 4 to the left or to the right slippage go out high order end or the low order end of blackboard body 5, then can be rotated by Revolving blackboard body 5.
