Abstract
A multifunctional layering blackboard is formed by combining ordinary blackboards and a liquid crystal display screen in a layering way, wherein a motor is arranged above each blackboard, and the liquid crystal display screen can automatically ascend and descend through multiple guide rails on the edges of the blackboards, so that the layering variation of multiple blackboards can be realized. By adopting the scheme, defects that the traditional blackboard is only used for writing characters and cannot realize the video playing and cannot show sound, pictures and the like can be overcome, the conversion of the blackboards and the electronic display screen is conveniently realized through a simple button, so that display of characters, images and sound on the blackboard can be realized.
Description
Technical field
The utility model relates to a kind of blackboard, specifically has the blackboard of Multifunctional layered structure.
Background technology
At present, science and technology is maked rapid progress, but the major way that transmits wisdom and imparts knowledge to the student on school classroom remains blackboard.The shortcoming of traditional blackboard is: can only realize single character calligraph, can not realize sound, picture, video teaching content.LCDs has also been installed by many schools, but because blackboard has accounted for the centre position in classroom, and display screen must be installed in a jiao of classroom, student viewing gets up very inconvenient.
The utility model content
Single character calligraph can only be carried out in order to overcome traditional blackboard, the shortcoming of sound, picture, video teaching content can not be realized.The utility model proposes a kind of Multifunctional layered blackboard and solve this problem, its beneficial effect is, makes the blackboard can writing words, can use simultaneously sound, picture, video again.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Multifunctional layered blackboard of the present utility model, formed by LCDs, normal blackboard, the motor of blackboard top, guide rail and the control button at blackboard edge, described LCDs and normal blackboard layering, rotation by the motor above the described blackboard makes LCDs along the guide rail automatic lifting.
Description of drawings
Below in conjunction with accompanying drawing the utility model is briefly explained.
Fig. 1 is the utility model structural representation.
1. LCDs among the figure, 2. blackboard, 3. LCDs storeroom, the 4. motor of blackboard top, the 5. guide rail at edge, 6. control button.
The specific embodiment
In the embodiment in figure 1, we further specify the utility model as example to implement a kind of Multifunctional layered blackboard:
In Fig. 1, the layering blackboard is respectively by normal blackboard, and two parts of LCDs form.Generally this device is exactly a common blackboard, and LCDs leaves a placement LCDs storeroom 3 of the top of blackboard in.When needs use LCDs, press control button 6, motor 4 rotates and allows the LCDs of top lower along the guide rail 5 at blackboard edge, the contents of courses such as the video plug wire that then accesses the external power supply of display screen just can play sound by computer or other sound, video playback apparatus, image, picture, video.
This programme is by arranging a motor, makes the LCDs can lifting in conjunction with several guide rails at blackboard edge, thereby realizes that the layering between several blackboards changes.
Adopted scheme of the present utility model, having broken away from traditional blackboard can only writing words, can not realize video playback, etc. shortcoming, can pass through a simple button, change easily between several blackboards and the electronic display realizing, to realize the displaying at the enterprising style of writing word of blackboard, image, sound.Then avoided the traditional blackboard dust more by a kind of lifting design, the problem that LCDs is polluted.
Claims (1)
1. Multifunctional layered blackboard, formed by LCDs (1), normal blackboard (2), the motor (4) of blackboard top, guide rail (5) and the control button (6) at blackboard edge, described LCDs (1) and normal blackboard (2) layering, it is characterized in that, rotation by the motor (4) above the described blackboard makes LCDs (1) along guide rail (5) automatic lifting.
