Abstract
The invention discloses a turnover blackboard which comprises a plurality of strip-shaped blackboard units. Rotating shafts are arranged at the two ends of each strip-shaped blackboard unit and penetrate through supporting frames, worm wheels are arranged on the rotating shafts and engaged with worms in F-shaped beams, and an output shaft of a motor is connected with the worms through a transmission mechanism. The blackboard structure similar to a blind window is adopted, and thus available resources of the blackboard are increased.
Description
Technical field
The invention belongs to teaching aid technical field is and in particular to a kind of turnover blackboard.
Background technology
Blackboard common on the market at present includes traditional one side blackboard or rises pull-type Dual-side blackboard, one side blackboard book
Write after plate face expired, need manual erasing out handwriting, add substantial amounts of work to teacher, Dual-side blackboard has the superior of a bit
Property, however it is necessary that two boards face, need the sheet material resource doubling.
Content of the invention
According to above the deficiencies in the prior art, the technical problem to be solved is to propose a kind of turnover blackboard, real
Existing two-sided write, expand and write plate face, and economize on resources.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of turnover blackboard, including multiple strips
Blackboard unit, the two ends of described strip blackboard unit are provided with rotating shaft, and described rotating shaft passes through bracing frame, and rotating shaft is provided with worm gear, snail
Wheel is ratcheting with the worm screw in " F " type beam, and motor output shaft couples worm screw by drive mechanism, and support frame as described above is multiple for being provided with
The bar shaped support of waist-shaped hole, described strip blackboard unit passes through described waist-shaped hole, and the worm screw in described " F " type beam is located at " F " type
The side wall of beam inner chamber, the described the tip of the axis that turns is provided with cylinder right angle gear, and cylinder right angle gear is resisted against the side of " F " type beam inner chamber
On wall.
Present invention has the advantages that:The present invention, using the blackboard structure of similar shutter, increased the available resources of blackboard.
Brief description
Below the labelling of the content expressed by this specification accompanying drawing and in figure is briefly described：
Fig. 1 is the blackboard structure figure of the specific embodiment of the present invention.
Fig. 2 is top view in the specific embodiment of the invention " F " type beam.
Wherein, 1 strip blackboard unit, 2 rotating shafts, 3 bracing frames, 4 " F " type beam, 5 worm screws, 6 worm gears, 7 bearings.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, for example involved each component of the specific embodiment of the present invention
Shape, construction, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to the inventive concept of the present invention, technology
Scheme has more complete, accurate and deep understanding.
The turnover blackboard that the present invention provides, includes multiple strip blackboard units, and one piece of multiple strip blackboard units composition is black
Plate, similar to the structure of shutter, the two ends of strip blackboard unit are provided with rotating shaft, and rotating shaft passes through bracing frame, and bracing frame is to strip
Blackboard unit plays a supportive role, and rotating shaft is provided with worm gear, and worm gear is ratcheting with the worm screw in " F " type beam, and motor output shaft passes through to pass
Coupling worm screw, in actual use, motor drives worm movement to motivation structure, and worm screw drives the gear synchronous in rotating shaft
Motion.Bracing frame is the bar shaped support being provided with multiple waist-shaped holes, and strip blackboard unit passes through waist-shaped hole, the worm screw in " F " type beam
It is located at the side wall of " F " type beam inner chamber, " F " type limits worm screw so as to move along the direction of beam, turning the tip of the axis, to be provided with cylinder straight
Angle gear, cylinder right angle gear is resisted against on the side wall of " F " type beam inner chamber, to increase the stability of rotating shaft.
Above in conjunction with accompanying drawing, the present invention is exemplarily described it is clear that the present invention implements is not subject to aforesaid way
Restriction, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and the design of the present invention and technical scheme are directly applied to other occasions, all within protection scope of the present invention.This
Bright protection domain should be defined by the protection domain that claims are limited.
