The connection of one driven sheave 31, the rotation of driving sheave 30 drive the rotation of the first driven sheave 31, and the first driven sheave 31 passes through rope
It is connect with the second driven sheave 32, the rotation of the first driven sheave 31 drives the rotation of the second driven sheave 32, the second driven sheave 32
It is connect by rope with double track sheave 10, the rotation of the second driven sheave 32 drives double track sheave 10 to rotate;
8 side wall of cabinet is fixedly installed with fixing axle 9, and movable sleeve is equipped with double track sheave 10 in fixing axle 9, goes back in fixing axle 9
Movable sleeve is equipped with locked runner 11, has buckle outstanding on locked runner 11, cooperates the buckle slot on telescopic rod 20 to use, when not
It needs to make to be stuck in buckle slot in use, need to only rotate locked runner 11, even if student sits down, hoisting frame 19, limit
Frame 14 and hang plate 26 will not be opened, and traction rope 12 is fixedly connected in double track sheave 10, and the rotation of double track sheave 10 is led
The other end of messenger 12, traction rope 12 is fixedly connected with connecting rod 13, and connecting rod 13 moves out under the action of squeezing spring 21, even
Bar 13 is fixedly connected with position-limited rack 14, and the movement of connecting rod 13 drives position-limited rack 14 to move, and the effect of position-limited rack 14 is the body for making student
Body and desktop 7 keep certain distance, and the bottom of position-limited rack 14 is fixedly installed with rack gear 15, and the movement band carry-over bar 15 of position-limited rack 14 is transported
Dynamic, rack gear 15 is engaged with gear 16, and the movement band moving gear 16 of rack gear 15 rotates, and fixing sleeve is gone back on the axis of gear 16 equipped with upgrading slot
Wheel 17, the rotation of gear 16, which drives, promotes the rotation of sheave 17, is promoted and is fixedly connected with hoisting rope 18 in sheave 17, promotes 17 turns of sheave
Dynamic that hoisting rope 18 is driven to be pulled up, the other end of hoisting rope 18 is fixedly connected with hoisting frame 19, and hoisting rope 18, which is pulled up, to be made
Hoisting frame 19 moves upwards, and the effect of hoisting frame 19 is that student head and desktop 7 is made to keep certain distance, fixed company on connecting rod 13
It is connected to telescopic rod 20, is arranged in telescopic rod 20 and squeezes spring 21, squeezes spring 21 for telescopic rod 20 outwardly against telescopic rod 20
It is fixedly installed with limited block 22 far from the one end for squeezing spring 21, limited block 22 does not depart from telescopic rod 20 on fixed block 201.
Connecting rod 23 is preferably fixedly installed on telescopic rod 20 as one, movable sleeve, which is equipped with, in connecting rod 23 sticks up bar 24,
Being moved by telescopic rod 20 drives connecting rod 23 to move, and the movement of connecting rod 23, which drives, sticks up the movement of bar 24, sticks up in bar 24 and is flexibly connected
There is fixing axle 25, fixing axle 25 can be moved sticking up in bar 24, stick up side of the bar 24 far from connecting rod 23 and hang plate 26 is fixed
Connection is promoted hang plate 26 by sticking up the movement of bar 24, and the effect of hang plate 26 is to form the books of student and desktop 7 centainly
Angle, facilitate students ' reading, hang plate 26 is movably arranged in rotary axis groove 28 by shaft 27, and hang plate 26 surrounds shaft 27
Movement, is allowed to not depart from desktop 7, rotary axis groove 28 is provided in desktop 7.
Working principle:When student, which stirs seat 6, to be sat on, the rotation of seat 6 drives seat shaft 5 to rotate, and seat turns
The rotation of axis 5 drives driving sheave 30 to rotate, and the rotation of driving sheave 30 drives the rotation of the first driven sheave 31, the first driven sheave 31
Rotation drives the rotation of the second driven sheave 32, and the rotation of the second driven sheave 32 drives double track sheave 10 to rotate, and 10 turns of double track sheave
Dynamic drawing traction rope 12, connecting rod 13 move out under the action of squeezing spring 21, and the movement of connecting rod 13 drives position-limited rack 14 to move,
Position-limited rack 14 is opened at this time, so that the body of student and desktop 7 be allowed to keep certain distance, is synchronized, and the movement of position-limited rack 14 drives
Rack gear 15 moves, and the movement of rack gear 15 is rotated with moving gear 16, and the rotation of gear 16, which drives, promotes the rotation of sheave 17, promotes 17 turns of sheave
Dynamic that hoisting rope 18 is driven to be pulled up, hoisting rope 18, which is pulled up, opens up hoisting frame 19, to make student head and table
Face 7 keeps certain distance, synchronizes, and is moved by telescopic rod 20 and connecting rod 23 is driven to move, and bar is stuck up in the movement drive of connecting rod 23
24 movements are promoted hang plate 26 by sticking up the movement of bar 24, thus keep the books of student and 7 shape of desktop at a certain angle, side
Just students ' reading, when student stands up, driving sheave 30 drives traction rope 12 to move, and each component is extensive under the traction of traction rope 12
Shape is restored, if not needing to open above-mentioned component, only need to rotate locked runner 11, the buckle on locked runner 11 is made to be stuck in buckle slot
Interior, even if student sits down, hoisting frame 19, position-limited rack 14 and hang plate 26 will not be opened, and student is facilitated according to circumstances to use.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
