Application method after on furniture specifically on vertical computer desk, to be illustrated exemplified by being used as computer desktop, this
When, computer desktop is work top, in use, computer desktop under the drive of upper foldable assembly and lower foldable assembly together from upper
Under, extension expansion from inside to outside, when not in use, outer support part is promoted inwards, computer desktop i.e. can be in upper foldable assembly
Under drive with lower foldable assembly from bottom to top, receive and fold from outside to inside, collapsed completely when being in vertical state to computer desktop, its
It is easy to use, and the space-consuming of furniture is effectively reduced, and also it is received and folded quickly, conveniently, stably.
Further, the left folding component includes lower-left folding arm and folds the workbench above arm, institute positioned at lower-left
State workbench and lower-left folds upper and lower part of the left end of arm respectively with external fixing rack and is hinged, the lower-left folds the right-hand member of arm
By lower universal driving shaft and linkage rack lower hinge, the central bottom of the workbench is cut with scissors by the top of upper universal driving shaft and linkage rack
Connect, the right-hand member of the workbench stretches out linkage rack to the top of right folding component.
Further, the right folding component includes upper right folding arm and bottom right folds arm, and the upper right folds arm and the right side
The lower left end for folding arm is hinged by upper universal driving shaft and the upper and lower part of lower universal driving shaft and linkage rack respectively, and the upper right folds
Arm and bottom right fold upper and lower part of the right-hand member of arm respectively with inner fixed stand and are hinged.
Further, the reinforcement assembly includes two reinforcing arms being hinged, the outer end difference of two reinforcing arms
Fold arm and bottom right with lower-left and fold arm and be hinged, the reinforcement assembly after the completion of being hinged folds arm with lower-left, bottom right folds arm and under
The diamond structure of universal driving shaft formation activity together.The setting of reinforcement assembly, diamond structure is combined together to form with lower folding arm,
Effectively avoid work top deploy or receive it is folded during occur rocking or offset the problem of, further ensure that work top exists
Expansion or the stability for receiving folded process.
Further, the external fixing rack, inner fixed stand and linkage rack are to be stamped to form using metal plate bending.Sheet metal component
