Operation principle: this device is provided with pen container, bookshelf and small blackboard, pen can be placed in pen container, by books by teacher
Place on the shelf, it is also possible to utilize small blackboard to calculate exercise question to students.During Accounting Course, exercise question is written on by teacher
On small blackboard, after exercise question is finished writing, starting motor, driven by motor small blackboard rotates 180 °, and on small blackboard, the one side with exercise question turns
To student, motor quits work, and when teacher needs to use pen and books, starts cylinder, and cylinder extends, and first piston promotes
Liquid in cylinder body moves up, and the 4th piston moves upward to left movement, elevating lever, the second slide block on the second slide rail upwards
Mobile, to place plate and move upward, the second pushing block rises and promotes the second lid to move upward, the second spring elongation, and pen container rises,
Second piston and the 3rd piston move right, and start electric pushrod simultaneously, and electric pushrod extends, and the first pushing block is transported the most to the right
Dynamic, the first lid is opened by the first pushing block, and electric pushrod stops elongation, and the 3rd spring elongation, bookshelf moves right, and stay cord pulls
Movable block moves right, and the first slide block moves right on the first slide rail, and the first spring is stretched, and small blackboard moves right, and makes
The student being positioned at right, classroom also is able to see the exercise question write on small blackboard clearly, when the second lid is opened completely, and pen container rises to
Suitable height, when bookshelf moves right to suitable position, cylinder stops elongation, and teacher can take pen and book very easily
This.After teacher takes pen and books, starting cylinder and shorten, the 4th piston moves right, and elevating lever moves downward, the second slide block
Moving down on the second slide rail, place plate and move downward, the second spring pulls the second lid to move downward, until the second lid
Son resets, and pen container declines, and the second piston and the 3rd piston are retracted to left movement, electric pushrod, and the 3rd spring pulls first to cover
Son is to left movement, until the first lid resets, bookshelf is moved to the left, and the first spring pulls movable block to be moved to the left, small blackboard
It is moved to the left, makes the exercise question that the student being positioned at left, classroom can also be seen that on small blackboard, when small blackboard is moved to the left to suitably
Position time, cylinder stop shorten.Starting cylinder elongation, cylinder resets, and cylinder stops elongation, pen container and bookshelf and resets, and starts
Motor, driven by motor small blackboard rotates 180 °, and small blackboard resets.
Because desktop right-hand member is provided with placing trough, in placing trough, can temporarily deposit some small articles.
Because being provided with ledge for chalk on blackboard bottom small blackboard, ledge for chalk on blackboard can place chalk, when teacher needs to use chalk little black
When writing on plate, chalk can be taken very easily, shorten the time by chalk, improve classroom efficiency.
Because also including storage tank, being provided with storage tank on the right side of right support, temporary transient no article can be put by teachers
Being placed in storage tank, the laying for goods on the desktop of dais is neat, it is possible to makes teacher student's body and mind happier, builds good
Learning atmosphere.
Because motor is servomotor, servomotor can precise rotation, the preferably speed of control pen container rising, bookshelf
The speed of movement and the speed of small blackboard motion.
Because the first pushing block and the second pushing block are block rubber, block rubber is soft, sends when reducing pushing block and cap contacts
Sound.
