One concrete application of the present embodiment are as follows: the present invention out of extension rail 3 by pulling out chair 2, the cunning of 4 end of side plate
The hanging plate of dynamic cooperation is greater than the outlet for hanging 17 end of T shape sliding rail of rail 3, will not be de- from rail 3 is hung when side plate 4 is slided along extension rail 3
Out, it is then driven by hand joystick 33 and adjusts the rotation of cone pulley 10 drive gear ring 8 and the rotation of adjustment barrel 6, the rotation of adjustment barrel forward direction
Turn to move down the foundation being threadedly coupled with adjustment barrel 67, move down while inside 20 mating sleeve 5 of limiting slot of foundation 7
Limit plate move down and not can rotate, since the turntable 11 and ground face contact, the adjustment barrel 6 of the connection of 7 lower rotation of foundation rotate
When turntable 11 not can rotate, will not make a sound, adjustment barrel 6, which moves down, increases chair 2 at a distance from ground, chair 2 is increased,
When chair 2 increases, the upward sliding in interior sliding rail 18 of side wall volume slide plate 19 increases steady, rotates backward joystick 33, can be with
It is retracted in foundation 7 in adjustment barrel 6, chair 2 can reduce height since self weight is along interior 18 slide downward of sliding rail, continue reversed
It shakes, chair 2 can be made to hang in interior sliding rail 18 by slide plate 18, so that foundation 7 continues to withdraw, so that foundation 7 be made to leave ground
Then chair 2 is pushed back and is hung in rail 3 by face, facilitate arrangement and sweep library, chair 2 is in good order, and library is clean and tidy, can be with
Low, raising comfort level and practicability is turned up.
By upward cocked eccentric compressive bar 25, makes the narrow wheel of eccentric compressive bar 25 against the side of chair 2, unclamps shaft 21,
To mitigate the extruding of 24 pairs of friction spring friction bottom sheet 23, reduces frictional force, at this moment can press against backrest 12, backrest 12 backward
21 rotations tilt backwards around the shaft, after mixing up angle, press down on eccentric compressive bar 25, make its chimb against the side of chair 2, will
Shaft 21 pulls out, and is pressed further by friction spring 24, increases the frictional force between friction upper piece 22 and friction bottom sheet 23, from
And the angle of backrest 12 is fixed, and when adjusting upward backrest 12, cocked eccentric compressive bar 25, due to the effect of tension spring 13, automatic pull-up
Backrest 12, then compresses eccentric compressive bar 25 again, and 12 adjustable angle of backrest improves comfort level, meets different needs.
When reading, plug in button can be held by hand and is slided backward along folding slot 28, is retracted in plate 27 in set frame 26, so
Contact the bottom bracing plate 32 of its bottom with desktop from Unscrew in window 15 is closed placement plate 16 afterwards, book-blocking bar 31 is upward at this time
It erects, books can be placed in placement plate 16, books tilts naturally, when reading, can not have to bow, mitigation shoulder neck is born
Load, do not have to it is hand steered, avoid hand from aching, promoted reading experience, using finishing, directly rotate placement plate 16, be received in conjunction window
It in 15, presses directly down, placement plate 16 opens plate 27 and enters conjunction window 15, and 27 automatic spring of plate blocks to which fixation is put
Set plate 16.
Then the present invention is driven by hand joystick 33 by pulling out chair 2 out of extension rail 3 and adjusts the rotation of cone pulley 10
Move down the foundation being threadedly coupled with adjustment barrel 67, adjustment barrel 6, which moves down, increases chair 2 at a distance from ground, by chair 2
It increases, rotates backward joystick 33, foundation 7 can be made to be retracted in adjustment barrel 6, chair 2 is downward along interior sliding rail 18 due to self weight
Sliding can reduce height, continue reversed shake, so that foundation 7 continues to withdraw, so that foundation 7 be made to leave ground, chair 2 is logical
It crosses slide plate 18 to hang in interior sliding rail 18, then chair 2 is pushed back and is hung in rail 3, facilitate arrangement and sweep library, chair 2 is in good order
Orderly, library is clean and tidy, and low, raising comfort level and practicability can be turned up.
By upward cocked eccentric compressive bar 25, makes the narrow wheel of eccentric compressive bar 25 against the side of chair 2, unclamps shaft 21,
At this moment backrest 12 can be being pressed against backward to tilt backwards, and after mixing up angle, press down on eccentric compressive bar 25, the angle of fixed backrest 12
Degree, when adjusting upward backrest 12, cocked eccentric compressive bar 25, due to the effect of tension spring 13, then automatic pull-up backrest 12 is pressed again
Tight eccentric compressive bar 25,12 adjustable angle of backrest improve comfort level, meet different needs.
Plug in button is held by hand to slide backward along folding slot 28, is retracted in plate 27 in set frame 26, then by placement plate
16, from Unscrew in window 15 is closed, contact the bottom bracing plate 32 of its bottom with desktop, and book-blocking bar 31 erects upwards at this time, can incite somebody to action
Books are placed in placement plate 16, and books tilt naturally, when reading, can not had to bow, be mitigated shoulder neck burden, do not have to it is hand steered,
It avoids hand from aching, promotes reading experience.
