Abstract
The utility model relates to a blackboard which can rotate. The utility model is composed of a plurality of dovetail plates. Literals and pictures written on the blackboard can be erased automatically, which can avoid the indoor dust flying to pollute the air and affect the health of the teaching personnel, and can also avoid the teaching personnel wiping the blackboard to reduce the labor intensity. The face of the blackboard can be rotated to rise optionally, which can solve the conflict of the dysgraphia because of the height of the teacher, and can not hinder the line of sight of students on the left and right sides of the front row. The utility model has the advantages of simple fabrication and convenient use.
Description
The utility model relates to a kind of blackboard of the usefulness of imparting knowledge to students.
The blackboard that uses is because of being subjected to the restriction of condition at present, often last class needs to wipe several times repeatedly, to cause the place to operate schools dust from flying, pollute room air, influence the healthy of faculty, last class hour of teacher should writing on the blackboard, erase the board again, labour intensity is big, causes dysgraphia and Chang Yin teacher's height is different, and usually causes contradictions such as the student who is sitting in front-seat the right and left does not see.
The purpose of this utility model is the weak point of avoiding above-mentioned in the prior art, can arbitrarily rotate and provide a kind of, literal, figure that book is write on the blackboard are random with being raised to ideal height on hand, to guarantee that each student can both see clearly Chu, do not need last class hour to erase the board, only need clean after school every day just, both avoided indoor dust from flying, influenced faculty's the healthy teacher's labour intensity of last class hour that alleviates again, and solve the teacher because of the different contradictions such as writing on the blackboard difficulty that cause of height, make to write comfortable belt Rotary Blackboard.
The purpose of this utility model realizes by following approach: be fixed with fixed head brush holder and bearings mounted support plate on the main frame, being fixed on flexibility also can be with the coattail board composing plate face of flexibility band rotation with going up.Runner supporting and the drive of flexible band by being connected with bolster.Bolster and bearing suit, the scrubbing brush of being close to coattail board are installed in the scrubbing brush resistance on the scrubbing brush frame, between scrubbing brush and the scrubbing brush frame spring are installed, and make scrubbing brush can be close to coattail board, and blackboard eraser is clean.
Belt Rotary Blackboard of the present utility model, scrubbing brush is made up of the scrubbing brush folder that connects by securing member and scrubbing brush support and fibre object.
The embodiment of concrete structure of the present utility model in conjunction with the accompanying drawings is described in further detail.

Fig. 3 belt Rotary Blackboard is just cuing open two views
As Fig. 1, shown in Figure 3, the plate face of belt Rotary Blackboard can constitute with the coattail board (1) that flexibility is rotated with (10) by being fixed on the flexible band (10).Runner (2) supporting and the drive of flexible band (10) by being connected with bolster (4), bolster (4) and bearing (3) suit, bearing (3) is installed, the support plate (5) that supports two bolsters (4) is fixed on the main frame (11), be fixed on the scrubbing brush resistance (8) that has prevention scrubbing brush (7) to fall on the scrubbing brush frame (6) on the support plate (5) and can guarantee to slide before and after the scrubbing brush (7), scrubbing brush (7) places in the scrubbing brush resistance (8), between scrubbing brush (7) and the scrubbing brush frame (6) spring (9) is housed, make scrubbing brush (7) close adhesion plate face, the plate face is wiped clean.
As shown in Figure 2, the scrubbing brush of belt Rotary Blackboard (7) is by the scrubbing brush folder (13) of gripping fibers thing (14), and the scrubbing brush support (12) of fixed head brush clamp (13) and connecting plate brush clamp (13) are formed with the securing member (15) of scrubbing brush support (12).
The utility model has the following advantages compared to existing technology: the plate face can arbitrarily rotate, and the energy automatic wiping is clean, can avoid indoor dust from flying, contaminated air, affect the healthy of faculty, can exempt the work that erases the board in the teachers ' teaching process, to reduce labor intensity, blackboard can arbitrarily rise, and has solved the teacher and has caused the contradictions such as dysgraphia because height is different, does not affect again front-seat the right and left student's vision, guarantee that each student can both see clearly Chu, writing on the blackboard is comfortable, makes simple, easy to use.
