Described desk side is provided with rotating shaft, this rotating shaft is connected with wiring dish 28, the lateral wall of the outside spoke of this wiring dish 28 is provided with ratchet 32, ratchet 29 is provided with above this ratchet 32, this ratchet 29 is flexibly connected with the minor axis be arranged on desk side, this minor axis is in the top of wiring dish 28, and described ratchet 29 is flexibly connected with ratchet 32, described rotating shaft outer end is connected with folding wind 33 after protruding ratchet 32, described desk side is provided with the tenth pulley 30, tenth pulley 30 be in ratchet 29 front and higher than ratchet 29 top, desk side below described tenth pulley 30 is provided with the 11 pulley 31, and the 11 pulley 31 flushes with the top of wiring dish 28 and front portion respectively, described desk side is provided with a cover 34, leaves gap between this cover 34 tops and desktop 20 bottom surface, and described ratchet 32, ratchet 29, minor axis, wiring dish 28, wind 33, the tenth pulley the 30, the 11 pulley 31 are in a cover 34, the 5th pulley 5 is provided with bottom described left side slideway 3, the bottom at described desk back is provided with the 6th pulley 13, 6th pulley 13 is close to left side slideway 3, the bottom at described desk back is provided with the 7th pulley 14, the left side edge of 7th pulley 14 near desk back, the top at described desk back is provided with the 8th pulley 18, the left side edge of 8th pulley 18 near desk back and desktop 20, the rear portion of described desk side is provided with the 9th horizontal pulley 19, 9th pulley 19 is near desktop 20, 9th pulley 19 is on same horizontal plane with the 8th pulley 18 and the tenth pulley 30 respectively, described 5th, six, seven, eight, nine, ten, 11 pulleys are semi-enclosed pulley, be provided with the second steel wire rope 4 bottom described left-side slide bar 22, the other end of this second steel wire rope 4 successively through bottom the first spring 2, left side slideway 3, the 5th, six, seven, eight, nine pulleys, door cover 34, the tenth, be connected with described wiring dish 28 after 11 pulleys.
When people will make lifter plate 1 rise for throw light on etc., 11 can be pushed down on the pedal, pedal 11 drives the first steel wire rope 6 to move down when moving down, first 6, steel wire rope drives pivot pin 21 to be moved to the left, namely pivot pin 21 is separated with the hole on left-side slide bar 22, left-side slide bar 22, right-side slide bar 26 quick and stable under the effect of the first spring 2 rises, and left and right side slide bar 26 drives lifter plate 1 to rise simultaneously.After when the first spring 2, upwards full extension is opened, left and right side slide bar also rises and puts in place, little groove on left-side slide bar 22 just in time with the circular hole on left side slideway 3 tube wall about vis-a-vis, little ball 23 is under the effect of the 3rd spring, its sub-fraction is protruded after circular hole and is embedded little groove, and the left-side slide bar 22 that risen and right-side slide bar 26 and lifter plate 1 are not easily rocked.After unclamping pedal 11, the first steel wire rope 6 can be loose, but can not depart from first, second, third and fourth pulley semienclosed.
After lifter plate 1 rises, illumination is used in this way at night, then can open the switch on controller, illuminating lamp 25 is that is shinny, because there being blocking of photo-shield strip, the light of illuminating lamp 25 is downward direct projections, can not be dazzling, the translucent front plate arranged makes light softer, can reach illuminating effect well again simultaneously.
People will practise handwriting drawing when waiting, and painting and calligraphy calligraphy or painting model directly can be swung to or be clipped on lifter plate 1, not only convenient but also save the space of desk.Drawing of practising handwriting night is also passable, and because lifter plate 1 is larger, the painting and calligraphy calligraphy or painting model swinging to or be clipped on lifter plate 1 can only block a part of light, can not affect people and to practise handwriting drawing.
In addition, during as the present invention is used as desk, the front plate on lifter plate 1 is translucent white board, and classmates can come suddenly to remember that teacher teaches main points etc. with the marking pen got ready etc., can improve the listening to the teacher of classmates, results of learning etc.
As the closedown that the lifter plate 1 of rise will be declined, a cover 34 can be opened, folding wind 33 is put down, and rotate wiring dish 28(ratchet 32 also synchronous rotary by wind 33), second steel wire rope 4 is constantly involved in by wiring dish 28, left-side slide bar 22 etc. is left behind by the second 4, steel wire rope, when left-side slide bar 22 decline puts in place, pivot pin 21 moves right under the effect of the second spring, the right head of pivot pin 21 can enter hole (hole mouth can be opened greatly) smoothly through after the tube wall of left side slideway 3, thus left-side slide bar 22 is located, simultaneously, also right-side slide bar 26 and lifter plate 1 are located.
Because the little groove on left-side slide bar 22 is shallow arcuation, can be separated with little ball 23 with comparalive ease, so moving up and down of left-side slide bar 22 can not be affected.After left and right side slide bar and lifter plate 1 decline, desktop 20 just seems larger, so that people are engaged in relevant matters.
If when pupils etc. rotate wiring dish 28 by wind 33, may require great effort, can stop in midway, but there is the setting of ratchet 32, ratchet 29,28 meetings of wiring dish rotate namely clockwise towards a direction, and can not reverse, and ensure the energy safety such as pupil, successfully the second steel wire rope 4 be involved in wiring dish 28, finally, left and right side slide bar 26, lifter plate 1 are all left behind; After this, then ratchet 29 is moved outward, ratchet 29 is separated with ratchet 32, like this, when lifter plate 1 need rise again, wiring dish 28 can not be affected and reverse, the second steel wire rope 4 in wiring dish 28 is rolled out smoothly.
Door cover 34 switches are very convenient, and can not tentacle.The universal wheel arranged, makes foot pedal apparatus 12 can follow desk movement flexibly together.Because foot pedal apparatus 12 is earlier, the pin of people is easy to step on.In concrete enforcement, by pipe very little on first and second steel wire loop, each pulley can be mixed capsule cover etc., not only safe but also attractive in appearance.5th pulley 5 than other pulley more greatly, ensures that the second steel wire rope 4 can not meet other parts after the 5th pulley 5, the 6th pulley 13.
As long as allow lifter plate 1 rise a part time, right-side slide bar 26 fixed by the screw on available right side slideway 27.In addition, by the elasticity of set screw, the rising or falling speed of right-side slide bar 26 and left-side slide bar 22 and lifter plate 1 is able to moderate.
When the present invention is used as desk, visual feelings storage battery is powered.During as other desk, directly can get final product (controller separately can establish a power line) by power line plug-in.
The various simple change made by those of ordinary skill in the art, remodeling all would not depart from the scope of the present invention.
