Abstract
The utility model discloses a blackboard with the light reflection degree capable of being adjusted. The technical scheme is that the blackboard comprises a blackboard body, one face of the board face of the blackboard body is provided with a sleeve which is connected with a support rod in a sleeved mode, and a forward-backward rotating motor is connected below the support rod. The forward-backward rotating motor drives the blackboard body to rotate, so that angles can be adjusted, angle adjusting can be achieved easily through a button, and the problem that teaching is affected by light reflection is avoided. The blackboard has the advantages that the light reflection angles of the blackboard body can be adjusted conveniently, teaching is not affected, moving is convenient, manpower is of no need, and class time can not be occupied.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of blackboard that can adjust the reflective number of degrees.
Background technology
It is often reflective that traditional blackboard is placed on the front, classroom, always there is visual dead angle in part student, more student do not have at present a kind of device that can automatically adjust blackboard angle, in the situation that does not take time in classroom, can adjust as early as possible its angle, so that can see literal.
The utility model content
The purpose of utility model is for a kind of blackboard that can automatically adjust angle is provided.
In order to reach as above purpose, the utility model is taked following technical scheme: comprise blackboard, on the one side of its non-blackboard panel cover is arranged, described cover is socketed on pole, and described pole below connects clockwise and anticlockwise motor.
Adopt as above the utility model of technical scheme, soluble at least problem is: clockwise and anticlockwise motor drives blackboard and can rotate, thereby adjusts angle, can easily realize angle adjustment by button, prevents reflective impact teaching.
The further technical scheme of the utility model is that described clockwise and anticlockwise motor is positioned at movable case.
The further technical scheme of the utility model is that there is movable pulley described movable case below.
The further technical scheme of the utility model is that described clockwise and anticlockwise motor connects pole after connecting deceleration device.
The further technical scheme of the utility model is that described movable pulley is universal wheel.
Adopt as above the utility model of technical scheme, have following beneficial effect: can conveniently adjust the reflecting angle of blackboard, not affect teaching, conveniently moving without manpower, can not take time in classroom.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1. overlap; 2. blackboard; 3. pole; 4. clockwise and anticlockwise motor; 5. movable case; 6. movable pulley.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described;
Comprise blackboard 2, cover 1 is arranged on the one side of its non-blackboard panel, described cover 1 is socketed on pole 3, and described pole 3 belows connect clockwise and anticlockwise motor 4.
Adopt as above the utility model of technical scheme, soluble at least problem is: clockwise and anticlockwise motor drives blackboard and can rotate, thereby adjusts angle, can easily realize angle adjustment by button, prevents reflective impact teaching.
Described clockwise and anticlockwise motor 4 is positioned at movable case 5.
Can guarantee the classroom image, can not make motor exposed.
There is movable pulley 6 described movable case 5 belows.
Because conveniently moving is adjusted fast position.
After connecting deceleration device, described clockwise and anticlockwise motor 4 connects pole 3.
The further technical scheme of the utility model is that described movable pulley 6 is universal wheel.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
