Belt wheel 15, the second belt pulley 16 and flat belt 17,1 top left of the first installing plate are equipped with decelerating motor 10,2 right wall of the first pillar
The second rolling bearing 11 is arranged on the downside of downside and 3 left wall of the second pillar, 4 bottom left end of the second installing plate and right end are symmetrically set
There is thrust bearing 12, screw 13, left silk are equipped in 12 and second rolling bearing 11 of thrust bearing of same vertical position
13 lower end of bar exports axis connection with decelerating motor 10, and 13 middle part of screw is equipped with nut 14, and nut 14 coordinates with screw 13, left and right two
It is connect between side nut 14 with big blackboard 7, screw 13 upper end in left is equipped with the first belt pulley 15, and screw 13 upper end in right is equipped with the
Two belt pulleys 16, the first belt pulley 15 are located at the spaced winding of 16 left of the second belt pulley, the first belt pulley 15 and the second belt pulley 16
There is flat belt 17, so when teacher needs writing on the blackboard, the higher place of big blackboard 7, which is write, will be relatively elaborate or to be write
Less than at this moment teacher positive can start decelerating motor 10, and the rotating forward of decelerating motor 10 can drive screw 13 to rotate, 13 turns of screw
Dynamic that the first belt pulley 15 can be driven to rotate, the rotation of the first belt pulley 15 can drive flat belt 17 to move, and flat belt 17 moves
The second belt pulley 16 is driven to rotate, the rotation of the second belt pulley 16 drives right side screw 13 to rotate, at this moment the screw 13 of the left and right sides
Rotation can cause big blackboard 7 to decline together, and reduction of speed motor is closed in the certain position dropped to, will subtract after having used big blackboard 7
Big blackboard 7 is resetted, is then shut off decelerating motor 10 by 10 reverse starting of speed motor.
Because the second sliding rail 18, the second mounting blocks 19, the second sliding block 20, spring 21, drawstring 22,23 and of curtain are further included
Transparent bag 24,4 forepart of the second installing plate left and right sides are arranged with the second sliding rail 18, and 18 lower part of the second sliding rail is located at big blackboard 7
Forepart, 18 right wall upper end of the second sliding rail of left are arranged with the second mounting blocks 19, left with 18 left wall upper end of the second sliding rail of right
With being arranged with the second sliding block 20 in the middle part of 18 left wall of the second sliding rail of right in the middle part of second sliding rail, 18 right wall, 20 top of the second sliding block with
Spring 21 is equipped between second mounting blocks, 19 bottom, 20 bottom of the second sliding block is equipped with drawstring 22,22 lower end of drawstring with it is big black
7 top of plate connects, and is equipped with curtain 23 between the second mounting blocks 19 and the second sliding block 20 of two sides of left and right, 23 forepart of curtain is uniformly set
There is transparent bag 24, so when teacher needs to show teaching card, decelerating motor 10 is so that big blackboard 7 moves down, at this moment greatly
Blackboard 7 can be by drawstring 22 toward drop-down, and drawstring 22, which moves down, drives the second sliding block 20 to move down, and spring 21 is stretched, and is rolled over
Folded curtain 23 will spread apart, transparent bag 24 open and flat will also come, and teacher can be placed in card in transparent bag 24 at this time,
When learning convenient for classmates, then big blackboard 7 is moved up, spring 21 resets, and curtain 23 can be folded again, will not
Hinder the writing on the blackboard of teacher.
Because having further included chalk holder 25, cover board 26 and partition board 27, chalk is equipped in the middle part of 2 left wall of the first pillar
Box 25, chalk holder 25 is interior to be equipped with partition board 27, and 25 top rotary type of chalk holder is equipped with cover board 26, so when teacher needs writing on the blackboard,
Teacher can turn on cover board 26, take out chalk out of chalk holder 25, and partition board 27 can be taken chalk with more convenient teacher.
Because having further included hook 28, brush 29 and lanyard 30,95 bottom right end of collection box is equipped with hook 28, links up on 28
Brush 29 is hung with, brush 29 is hung over by lanyard 30 on hook 28, so when the chalk dust in processing collection box 95 there are remnants now
As when, people can pick up brush 29 and dispose remaining chalk dust, hang back the extension of brush 29 on hook 28 i.e. after being finished
It can.
In order to clearly demonstrate the operation principle of the present apparatus, there is no draw leading for 13 nut 14 of screw in Figure of description
To device（The guider of 13 nut 14 of screw is generally sliding-rail sliding either linear guides）, in the real work of the present apparatus
In, the guider of 13 nut 14 of screw is to must have, and otherwise screw 13 rotates, and nut 14 also can be rotated and then, screw
The guider of 13 nuts 14 follows screw 13 to rotate for limiting nut 14, forces axial direction of the nut 14 along screw 13
Movement because the technical staff of machinery field is seen when having 13 14 device of nut of screw, is just necessarily known in this dress of actual fabrication
When putting, the guider of 13 nut 14 of upper screw rod is added, the guider of addition 13 nut 14 of screw does not need to machinery field people
Member pays performing creative labour and can be realized, and illustrates hereby.
