The use method of the lifting multifunctional deformable intelligent table provided by the invention is described as follows:
when a user wants to adjust the height of the lifting multifunctional deformable intelligent table, the second motor 5 is started first, the position of the lower clutch 14 is raised through the lower transmission screw 17 and the lower clutch shift fork 14-2, at this time, the upper end of the lower clutch short shaft 14-4 on the lower clutch 14 is inserted into the insertion hole on the lower bull gear power selector 11, and the lower end of the lower clutch short shaft 14-4 is pulled out from the insertion hole on the lower spindle driven sleeve power selector 15, so that the large motor 5 is disconnected from the transmission spindle 40. The large motor 5 is started, thereby driving the bottom large gear 19 to rotate through the large motor gear 16, and transmitting power to the lower clutch 14 through the lower clutch long shaft 14-2 except for the lower clutch shift fork 14-3. Then the power is transmitted to the lower gearwheel 10; the lower gearwheel 10 then drives the gears 12 on both sides of the lower gearwheel to rotate, thereby driving the screw nuts 23 fixed to the gears 12 on both sides of the lower gearwheel to rotate. The screw nut 23 rotates relative to the ball screw 21 sleeved with it, thereby driving the ball screw 21 to ascend or descend, and further driving the second layer table top 20 and all the components thereon to ascend or descend together until the top layer table top 24 reaches a proper height, and stopping the operation of the large motor 5.
When the user wants to unfold or retract the upper fan-shaped tabletop 26, the second motor 5 is started, the position of the lower clutch 14 is lowered through the lower driving screw 17 and the lower clutch fork 14-2, the upper end of the lower clutch stub 14-4 on the lower clutch 14 is disengaged from the insertion hole on the lower bull gear power selector 11, and the lower end of the lower clutch stub 14-4 is inserted into the insertion hole on the lower spindle driven sleeve power selector 15, so that the big motor 5 is disconnected from the lower bull gear 10. Starting the second motor 52, and raising the position of the upper clutch 41 by the upper clutch fork 41-2, wherein the upper clutch projections 14-4 on the upper clutch plate 41-1 are inserted into the plurality of insertion holes on the upper rotating plate power receiver 32, and the upper clutch projections 14-4 on the upper clutch lower plate 41-3 are disengaged from the plurality of insertion holes on the geneva sleeve power receiver plate 51; starting the large motor 5, thereby driving the bottom large gear 19 to rotate through the large motor gear 16, transmitting power to the transmission main shaft 40 through the lower clutch 14 and the lower main shaft driven sleeve 13 in sequence, driving the transmission main shaft 40 and the parts on the upper clutch 41 except for the shifting fork to rotate together, and then transmitting the power to the rotating plate 28 through the upper rotating plate power receiver 32; the rotation of the one-layer rotating plate 28 drives the upper-layer L-shaped bending plate 31 to rotate, and the upper-layer sector table top 26 is stretched by means of the distance difference formed by the rotation of the upper-layer L-shaped bending plate 31. Because the bearing roller 24-1 on the bottom surface of the top layer upper table surface 24 can slide on the curved surface of the top of the space cam 29, the top layer upper table surface 24 can ascend and descend according to the height difference of the circumferential wall of the space cam 29; when the upper segment table top 24 is moved outwardly along the upper segment table top slide rails 27 until it is unfolded by moving from below the upper segment table top 24 to the outside, the bearing rollers 24-1 will be located at the concave part of the top curved surface of the space cam 29, so that the upper segment table top 24 and the upper segment table top 26 are at the same height. When the upper layer of fan-shaped table top 26 is contracted, the bearing roller 24-1 is positioned at the inclined plane of the top curved surface of the space cam 29, thereby driving the upper table top 24 to be lifted integrally and leaving a space for the contracted upper layer of fan-shaped table top 26. And finally, the operation of the large motor 5 is stopped.
When a user wants to unfold or retract the lower fan-shaped tabletop 34, the second motor 52 is started on the premise that the large motor 5 is disconnected with the lower large gear 10, and the upper clutch 41 is lowered by the upper clutch fork 41-2, at this time, the upper clutch projection 14-4 on the upper clutch plate 41-1 is disengaged from the plurality of insertion holes on the upper rotating plate power receiver 32, and the upper clutch projection 14-4 on the upper clutch lower plate 41-3 is inserted into the plurality of insertion holes on the sheave sleeve power receiving plate 51; the large motor 5 is started, so that the large motor gear 16 drives the large bottom gear 19 to rotate, power is transmitted to the transmission main shaft 40 sequentially through the lower clutch 14 and the lower main shaft driven sleeve 13, the transmission main shaft 40 and parts except a shifting fork on the upper clutch 41 are driven to rotate together, and then the power is transmitted to the cylindrical cam 47 through the grooved pulley sleeve power receiving plate 51; the cylindrical cam 47 drives the sheave drive plate 43 connected with the cylindrical cam to rotate; when the dial needle 43-3 on the grooved wheel dial 43 enters the strip-shaped groove 42-2 on the grooved wheel 42, the grooved wheel 42 drives the grooved wheel upper gear 45 to rotate together; the sheave upper gear 45 drives the cam sleeve 50 and the lower-layer sector-shaped unfolding rotating component 48 to rotate through the sheave sleeve gear 44, so that power is transmitted to the lower-layer desktop unfolding rotating component 37; the lower L-shaped bending plate 36 starts to rotate under the driving of the lower tabletop unfolding rotating component 37, thereby driving the lower fan-shaped tabletop 34 to move outwards along the lower tabletop slide rails 35 until the upper tabletop 24 moves outwards from the lower part of the upper tabletop on the top layer to unfold. In the process, the inner end of the metal rod 49 of the lower fan-shaped unfolding rotating component moves the lower horizontal section in the groove 47-1 of the cylindrical cam 47 to the junction of the horizontal section and the thread section, and the poking needle 43-3 drives the grooved wheel 42 to rotate for 1/4 circles at the moment and just leaves the strip-shaped groove 42-2; the plate 43-2 is just clamped at the 1/4 arc 42-1 outside the sheave 42, so that the sheave 42 and the sheave upper gear 45 are locked and do not move, and the cam sleeve 50 is also locked and do not rotate, but the cylindrical cam 47 is still rotated under the driving of the transmission main shaft 40, so that the cylindrical cam 47 and the cam sleeve 50 generate relative motion, and further the metal rod 49 of the lower layer sector unfolding rotating component slides along the spiral section of the groove 47-1 on the cylindrical cam 47, and the lower layer table top 33 and the lower layer sector table top 34 and other structures are integrally lifted through the lower layer table top unfolding rotating component 37 until the lower layer sector table top 34 is lifted to be flush with the top upper table top 24, so that the integral unfolding of the table top is realized, and finally the operation of the large motor 5 is stopped. The retraction process is the reverse of the deployment process described above.
Through the mutual combination of the processes, the lifting, descending, contraction and expansion of the lifting multifunctional deformable intelligent table can be realized.
