Left push rod spring 509a, 509b be set in left push rod 507a, 507b it is upper and positioned at left back-up ring 5072a, 5072b with it is left
Upper vertical sleeve pipe 210a or lower-left are stood between sleeve pipe 220a.Right push rod spring 510a, 510b be set in right push rod 508a, 508b it is upper and
Stood positioned at right back-up ring 5082a, 5082b and upper right between sleeve pipe 210b or the vertical sleeve pipe 220b in bottom right.
Left spring column 511a, 511b is arranged on left push rod 507a, 507b left bullet by left spring column spring 5111a, a 5111b
In post installation groove 5071a, 5071b.Right spring column 512a, 512b is pushed away by right spring column spring 5121a, a 5121b installed in the right side
In bar 508a, 508b right spring column installation groove 5081a, 5081b.On upper left vertical rod 300a or lower-left vertical rod 400a surface
It is axially spaced to be provided with some left positioning through hole (not shown)s to be cooperated with left spring column 511a, 511b, in upper right
It is axially spaced on vertical rod 300b or bottom right vertical rod 400b surface to be provided with what some and right spring column 512a, 512b cooperated
Right positioning through hole (not shown).
Upper and lower latch assembly 500a, 500b need to left and right upper pright stanchion 300a, 300b or left and right lower vertical rod 400a,
When 400b is locked, first left and right upper pright stanchion 300a, 300b or left and right lower vertical rod 400a, 400b extension elongation are adjusted
To correct position, spanner 502a, 502b are then moved, drives left-hand rotation motion block 503a, 503a and right-hand rotation motion block 504a, 504b to turn
It is dynamic, in rotation process, left projection left raised 5031a, 5031a and right-hand rotation motion block 504a on left-hand rotation motion block 503a, 503a,
Right raised 5041a, 5041b on 504b touch left push rod 507a, 507b inclined-plane and right push rod 508a, 508b inclined-plane simultaneously
Left push rod 507a, 507b and right push rod 508a, 508b are pushed outwardly, left push rod 507a, 507b and right push rod 508a, 508b band
The left positioning that dynamic left spring column 511a, 511b and right spring column 512a, 512b are caught on upper left vertical rod 300a or lower-left vertical rod 400a is led to
In right positioning through hole on hole and upper right vertical rod 300b or bottom right vertical rod 400b, so as to left and right upper pright stanchion 300a, 300b or
Left and right lower vertical rod 400a, 400b are locked.When releasing locking, spanner 502a, 502b are moved in opposite direction, in left push rod
Under the effect of spring 509a, 509b and right push rod spring 510a, 510b elastic force, left push rod 507a, 507b and right push rod 508a,
508b is inwardly packed up so that left spring column 511a, 511b and right spring column 512a, 512b depart from upper left vertical rod 300a or lower-left vertical rod
The right positioning through hole on left positioning through hole and upper right vertical rod 300b or bottom right vertical rod 400b on 400a.
In addition, the lower backside in blank 200 is located at the underface point that sleeve pipe 210a is found in upper left and upper right founds sleeve pipe 210b
Rebounding device 600a, a 600b is not provided with, and when upper left vertical rod 300a and upper right vertical rod 300b is packed up, its end acts against bounce-back
On device 600a, 600b, certain cushioning effect is played, so as to effectively be protected to upper left vertical rod 300a and upper right vertical rod 300b.
When in use, upper left vertical rod 300a and upper right vertical rod 300b cover the lift whiteboard structure of the present invention along upper left is vertical
Pipe 210a and upper right found sleeve pipe 210b and slide out to correct position upwards and using upper latch assembly locking 500a, then stand upper left
The right pulley 310b of left chain wheel 310a and upper right vertical rod the 300b upper end of bar 300a upper ends is suspended on track 100, lower-left vertical rod
400a and bottom right vertical rod 400b founds sleeve pipe 220a along lower-left and bottom right is found sleeve pipe 220b and skidded off downwards so that lower-left vertical rod 400a
The driving wheel 420b that moves to right for moving to left driving wheel 420a and bottom right vertical rod 400b lower ends of lower end is contacted to ground and is used lower latch assembly
500b is locked.So, blank 200 can along transverse shifting, meanwhile, can be to blank by upper and lower latch assembly 500a, 500b
200 height is adjusted.
