The present invention uses as follows: be folded into chest by the drawing bench launched.First the drawing do not painted is placed in paper web, the drawing painted is placed on drawing and deposits in drawer; By full dimension folding reading rack folds flat in bookshelf drawer; Dismountable floating type folding T-square is unloaded down, is finally placed on cabinet interior; Pencil and drawing instrument all leave drawing instrument in deposits drawer; Unclamp internal and external threads bindiny mechanism, make the left and right sides separately, turn knobs makes tooth bar to minimum state, and lift V-type leg connecting rod, makes V-type leg draw close, unclamp and take down Fast detachable unit, rotatable bindiny mechanism and its underpart are pivoted, stirs the bar in folding fastener-horizontal component and folding fastener-vertical portion, make from this limiting condition to another limiting condition, namely complete the folding of folding fastener, complete above process and namely realize from deployed condition to folded state; Disconnect the switch of controllable gas spring, support bar is shunk the medial surface in sheet frame, close switch.Upset left panel, makes it to close with folding draughting board right panel, then by hasp and staple fastening, can decide suitcase or knapsack in its sole discretion by user according to use.
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, make the left and right sides separately, turn knobs makes tooth bar to minimum state, and lift V-type leg connecting rod, makes V-type leg draw close, unclamp and take down Fast detachable unit, rotatable bindiny mechanism and its underpart are pivoted, stirs the bar in folding fastener-horizontal component and folding fastener-vertical portion, make from this limiting condition to another limiting condition, namely complete the folding of folding fastener, complete above process and namely realize from deployed condition to folded state.
Second step, by folded state to deployed condition, stirs the bar in folding fastener, makes from this state to another limiting condition, rotates V-type leg, with Fast detachable unit, V-type leg and rotatable connection is fixed, push V-type leg aside to limiting condition.Then universal joint, universal joint connecting rod, internal and external threads bindiny mechanism are coupled together, turn knobs, the power of rotation makes the right and left rise by universal joint, universal joint connecting rod simultaneously.Complete above process namely to realize from folded state to deployed condition.
The folding draughting board of adjustable-angle of the present invention uses as follows: be launched into drawing bench by the draughting board folded.First hasp and staple are unclamped; Upset left panel, makes the left/right panel after expansion be in same level height, makes the loop hook on horizontal fastening mechanism fasten shackle, rotating spanner fastening.Disconnect the switch of controllable gas spring, forward support bar to suitable angle, close switch.
Second step, clamping process.Under original state, there is not elastic deformation in the spring in slider bar; By rotating clamping knob, by the rotation of the first cam and the second cam, top board frame is moved right under the action of the spring, U-shaped grapple also thereupon right direction move, thus the L shape base be fixed on left panel is also moved thereupon, thus left panel is moved near right panel at the left sheet frame of folding draughting board, reduce finedraw, make left panel and right panel clamp under the action of the spring.
3rd step, dispose procedure.When the first cam and the second cam rotate by continuation, the first cam and the second cam back down top board frame makes top board frame move to left, and U-shaped grapple also moves to left thereupon and promotes L shape base, then makes left panel move to left and carries out reset release.
4th step, is folded into handbag by the draughting board launched.Disconnect the switch of controllable gas spring, support bar is shunk the medial surface in sheet frame, close switch.Upset left panel, makes it to close with folding draughting board right panel, then by hasp and staple fastening.
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 is pressed into by horizon rule in the short chi knob of cantilever.Improve the short chi knob of cantilever, pressing spring compresses, the shorter chi knob of the cantilever rotating both sides, and the hole exterior feature of cantilever short chi knob outline and horizon rule both sides is overlapped.Then the hole of vertical multifunctional ruler exterior feature is embedded in the outline of hovering knob, improve hovering knob, simultaneously rotate hovering knob again, make the hole exterior feature of hovering knob and vertical multifunctional ruler in vertical state.
Second step, the vertical multifunctional ruler of mobile hovering.Press hovering baffle ring, vertical multifunctional ruler can move freely in the hole slot of horizon rule, and when moving to desired position, unclamp hovering shelves ring, vertical multifunctional ruler is fixed on this position.
3rd step, dismantles vertical multifunctional ruler, draws the circle of arbitrary size.Rotate hovering knob, make hovering knob outline identical with the hole exterior feature of vertical multifunctional ruler, take out vertical multifunctional ruler.Determine home position in drawing, pin center of circle button and overlap with home position, then according to circle size Selection be equidistant hole or strip hole.If draw the circle of integer size, inserted by nib in the hole of corresponding size, pen encloses around center of circle button rotation one, draws out the circle of integer size; If draw the circle of non-integer size, regulate circle adjusting knob to required size, by nib near circle adjusting knob, pen encloses around center of circle button rotation one, draws out the circle of non-integer size.
The full dimension folding reading rack of 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 and bookshelf drawer inside is put in full dimension vertical rod rotation.Secondly, rotate full dimension swingle, it is all put into bookshelf drawer inside.Then with the hands arrest reading frame plate and complete to full dimension revolving part, full dimension pole etc. dimension support is put into bookshelf drawer inside, and reading frame plate is embedded in bookshelf drawer completely.Frame plate back-up block of finally reading embeds in reading frame plate.Complete above process namely to realize from deployed condition to folded state.
Second step, by folded state to deployed condition.First, reading frame plate is extracted out in bookshelf drawer.Secondly, rotate full dimension vertical rod to making folding fastener self-locking, holding position is constant.Then, frame plate back-up block of reading launches.Finally, the position of reading frame plate is put by regulating full dimension support just can be wanted arbitrarily.Complete above process namely to realize from folded state to deployed condition.
