Abstract

The utility model relates to a movable type multifunctional blackboard, which is composed of a multifunctional movable frame, a blackboard surface, a plurality of hanging hooks and clamps, and a dust box, etc. The blackboard can be moved vertically or horizontally in a certain range through a moving device. The hanging hooks and the clamps can expediently display the correlative hanging and clamping teaching objects, and the dust box under a sliding groove can effectively collect chalk dust and crumb.

Description

Portable multi-function blackboard
Affiliated technical field:
The utility model relates to a kind of basic facilities of teaching demonstration content, especially have multi-function blackboard mobile, overlapping combination.
Background technology:
In present teaching, blackboard remains teachers and students and shows knowledge, carries out the important platform of exchange and interdynamic, almost is requisite main teaching facilities in all classroom.But because traditional normal blackboard fixed-site is motionless, plate face fixed single, increase at current classroom knowledge capacity, student's quantity increases, student's health increases under the bigger situation of variation, the drawback of blackboard also comes out thereupon, the blackboard position is too high, and sawed-off teacher, student can't write, and blackboard is too low, the number of student that does not see blackboard is too many again, high and low position is moderate, writes in the content on the blackboard left side, and the classmate that the right is forward is not easy to see clearly, write in the content on blackboard the right, the classmate that the left side is forward is not easy again to see clearly.Simultaneously, the position is moderate also to be the thing in a period of time, because student's height, seat, and student's (height, brachium vary with each individual) of teacher, demonstration on class is not a constant number, earthquakes at any time.Therefore, current position is fixed, and the fixing blackboard of plate face has directly influenced the progress and the teaching effect of teaching.In addition, because the fixed-site of blackboard, literal on the blackboard, diagram are also fixed, the student stares at blackboard with what a fixing posture and fixing eye were concentrated one's energy for a long time, health is had very serious potential hazard, and the student who adverse consequences such as the different spinal curvature of degree, eyesight decline, stravismus occur is not within minority.Because the plate face is limited, writing font can not be too big, and too big blackboard capacity is little, need erase the board repeatedly, loses time dust from flying, contaminated air, harmful teachers and students' health.But even to this day, can replace the blackboard function, avoid the substitution goods of above drawback, even the similar facility of obvious results, in open publication and open teaching place, still do not occur.
Summary of the invention:
Task of the present utility model provides a kind of basic facilities with teaching demonstration content of mobile, overlapping combination function, it can arbitrarily move (vertical, level) position within the specific limits, increase the blackboard panel load number, cheap teachers and students write, help student's demonstration teaching content, for the teacher provides the necessary apparatus of preparing lessons in advance, write capacity thereby increase classroom instruction, promote the raising of quality of instruction.
In order to solve above-mentioned task, the solution that the utility model adopts is: can do vertical (up and down), level (about) a fixing blackboard is installed on the roll-out tray housing that slides, be referred to as the blackboard base plate, the suitable sliding tray (2--3 road) of quantity is installed in the lower edge on the housing that this bottom blackboard is installed, (the plate face is 1/3 of a base plate to the contour standby small blackboard that can write in the two sides of installation respective numbers on sliding tray, 1/2 two kinds of specifications), the blackboard of each aspect is made of with the small blackboard of homalographic side by side the 2--3 piece, and they can do free horizontal movement in sliding tray.Therefore the quantity of blackboard can be increased to the fixedly several times of blackboard of single face, because small blackboard is easy to loading and unloading, lecturing content can be written on the small blackboard in advance, and small blackboard can load and unload voluntarily, needs in the control that fixes of sliding tray two ends installation side bumper for preventing landing.Blackboard is moving to the suitable location need by the locator fixed position, and the blackboard upper ledge is along installing hanging hook, Articles-hanging clip, and lower frame contains and wipes the chalk dust and the chip of falling on the blackboard along the dust box is set under the sliding tray, avoids the ground of being scattered, contaminated air.
According to the architectural feature of blackboard, need in conjunction with objective reality, the motion of blackboard can be slided underframe, sliding tray (vertical, level) device is made into hand, perhaps electrodynamic type.According to the teaching practice needs, the quantity of the sliding tray on the Sliding blackboard underframe and blackboard quantity can increase and decrease when mounted.
Owing to adopt the level of to do, vertical mobile in the above-mentioned solution, the blackboard that polylith plate face combines.During teaching demonstration, can adjust as required blackboard vertical (just), level (about) position, satisfy the demand of viewing and emulating of diverse location student in the classroom as far as possible.Increasing of blackboard quantity, the capacity of writing increases thereupon, can expand and enrich the knowledge quantity of giving lessons, thereby improve the ageing of teaching.Can reduce last class hour to the wiping number of times or exempt of blackboard to the wiping of blackboard, unified finishing in the time of can focusing on rest after class to wiping of blackboard, blackboard underframe below is provided with the dust box in addition, and the pollution that can alleviate air is reclaimed and is write the dust chip.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is portable multi-function blackboard structure principle perspective view.
Fig. 2 is portable multi-function blackboard base plate plan view.
Fig. 3 is that sliding tray is installed three (1/3 style) small blackboard plan views.
Fig. 4 is that sliding tray is installed two (1/2 style) small blackboard plan views.
