The present invention uses as follows:Chest is folded into by the drawing bench deployed.The drawing not painted is placed in paper web first, the drawing painted is placed in drawing storage drawer;By full dimension folding reading rack folds flat in bookshelf drawer;Dismountable floating type folding T-square is unloaded down, cabinet interior is finally placed on;Pencil and drawing instrument are stored in drawing instrument storage drawer;Unclamp internal and external threads bindiny mechanism, separate the left and right sides, turn knobs make tooth bar to minimum state, lift V-type leg connecting rod, draw close V-type leg, Fast detachable unit is taken down in release, rotatable bindiny mechanism and its underpart are pivoted, the bar in folding fastener-horizontal component and folding fastener-vertical portion is stirred, made from the limiting condition to another limiting condition, the folding of folding fastener is completed, it is to realize from deployed condition to folded state to complete above procedure;The switch of controllable gas spring is disconnected, support bar is shunk into the medial surface in sheet frame, closure switch.Left panel is overturn, is allowed to close with folding draughting board right panel, then hasp and staple are fastened, can be by user according to using deciding suitcase or knapsack in its sole discretion.
The height-adjustable collapsible table leg of the present invention uses as follows:The first step, by deployed condition to folded state.Unclamp internal and external threads bindiny mechanism, separate the left and right sides, turn knobs make tooth bar to minimum state, lift V-type leg connecting rod, draw close V-type leg, Fast detachable unit is taken down in release, rotatable bindiny mechanism and its underpart are pivoted, the bar in folding fastener-horizontal component and folding fastener-vertical portion is stirred, made from the limiting condition to another limiting condition, the folding of folding fastener is completed, it is to realize from deployed condition to folded state to complete above procedure.
Second step, by folded state to deployed condition, stirs the bar in folding fastener, makes from the state to another limiting condition, rotates V-type leg, fixes V-type leg and rotatable connection with Fast detachable unit, push V-type leg aside to limiting condition.Then universal joint, universal joint connecting rod, internal and external threads bindiny mechanism are connected, turn knobs, the power of rotation makes the right and left rise simultaneously by universal joint, universal joint connecting rod.It is to realize from folded state to deployed condition to complete above procedure.
The folding draughting board of the adjustable-angle of the present invention uses as follows:Drawing bench is launched into by the draughting board folded.Hasp and staple are unclamped first;Left panel is overturn, the left/right panel after expansion is in same level highly, the loop hook on horizontal fastening mechanism is clasped shackle, rotating spanner is simultaneously fastened.The switch of controllable gas spring is disconnected, support bar is gone into suitable angle, closure switch.
Second step, clamping process.Under original state, elastic deformation does not occur for the spring in slider bar;By rotating clamping knob, by the rotation of the first cam and the second cam, so that top board frame moves right under the action of the spring, also right direction is moved U-shaped grapple therewith, so that the L-shaped base being fixed on left panel is also moved, so that left panel moves close to right panel in folding draughting board left plate frame, thin seam is reduced, left panel and right side board clamping are made under the action of the spring.
3rd step, discharges process.When continuing to rotate the first cam and the second cam, the first cam and the second cam top open top board frame and move to left top board frame, and U-shaped grapple also moves to left promotion L-shaped base therewith, left panel is moved to left progress reset release.
4th step, handbag is folded into by the draughting board deployed.The switch of controllable gas spring is disconnected, support bar is shunk into the medial surface in sheet frame, closure switch.Left panel is overturn, is allowed to close with folding draughting board right panel, then hasp and staple are fastened.
Dismountable floating type folding T-square of the present invention uses as follows:The first step, installs horizon rule and vertical multifunctional ruler.The short chi knob of hinged cantilever, makes its outline identical with the hole exterior feature of horizon rule both sides, then horizon rule is pressed into the short chi knob of cantilever.The short chi knob of cantilever is improved, pressing spring is compressed, then rotates the short chi knob of cantilever of both sides, the short chi knob outline of cantilever and the hole exterior feature of horizon rule both sides is overlapped.Then by the outline of the embedded knob that hovers of the hole exterior feature of vertical multifunctional ruler, hovering knob is improved, while rotating hovering knob again, makes hovering knob wide in vertical state with the hole of vertical multifunctional ruler.
Second step, the mobile vertical multifunctional ruler that hovers.Hovering baffle ring is pressed, vertical multifunctional ruler can be moved freely in the hole slot of horizon rule, when being moved to desired position, unclamp hovering shelves ring, vertical multifunctional ruler is fixed on the position.
3rd step, dismantles vertical multifunctional ruler, draws the circle of arbitrary size.Rotation hovering knob, makes hovering knob outline identical with the hole exterior feature of vertical multifunctional ruler, takes out vertical multifunctional ruler.Home position in drawing is determined, center of circle button is pinned and is overlapped with home position, is equidistant hole or strip hole then according to round size selection.If drawing the circle of integer size, nib is inserted in correspondingly sized hole, pen is enclosed around center of circle button rotation one, draw out the circle of integer size;If drawing the circle of non-integer size, nib is abutted circle adjusting knob by regulation circle adjusting knob to required size, and pen is enclosed around center of circle button rotation one, draws out the circle of non-integer size.
The full dimension folding reading rack of the drawer type of the present invention uses as follows:The first step, by deployed condition to folded state.First, pin folding fastener locking press button full dimension vertical rod rotation is put into inside bookshelf drawer.Secondly, full dimension swingle is rotated, its whole is put into inside bookshelf drawer.Then with the hands hold reading frame plate the full dimension support such as full dimension revolving part, full dimension pole is put into inside bookshelf drawer, and reading frame plate is completely embedded into bookshelf drawer.Finally the support block insertion of reading frame plate is read in frame plate.It is to realize from deployed condition to folded state to complete above procedure.
Second step, by folded state to deployed condition.First, reading frame plate is extracted out out of bookshelf drawer.Secondly, full dimension vertical rod is rotated to folding fastener self-locking is made, and holding position is constant.Then, by reading frame plate support block expansion.Finally, it just can obtain any position for wanting to put reading frame plate by adjusting full dimension support.It is to realize from folded state to deployed condition to complete above procedure.
