Table body base 1 plays the effect of supporting whole desk, and guide rail, synchronous pulley and motor are all connected on a body base. WholeThe power of elevating mechanism is provided by Worm reduction motor, and this motor is driven and speed governing in conjunction with H bridge circuit by single-chip microcomputer, realizesThe lifting of whole mechanism and electrodeless adjusting, and the electric self-locking of setting up on mechanical self-latching by motor and circuit realizes a body jointlyThe self-locking of adjustable height. The main shaft of Worm reduction motor is connected with synchronous pulley, and synchronous pulley drives Timing Belt vertical sideTo motion. Timing Belt and lifting platform and slide block are fixed together, and lifting platform is fixedly connected with support bar. Slide block is connected with guide railCan only move up and down along vertical direction by restrict lifting platform, support bar also can play restriction with being connected of linear bearing,Like this, the rotation of Worm reduction motor just can convert lifting platform to along the moving of guide rail, thereby makes support bar energy linear axisHold in the vertical direction motion. Support bar top is connected with table body, thereby realizes the height electrodeless adjusting of table body. Be provided with chain of commandPlate conveniently carries out control operation. Be provided with mechanical stroke switch adjustable range is limited, whole elevating mechanism can be realized desk700～1050mm step-less adjustment, to be applicable to the user of the different stature ratios of different height, makes drawing course more comfortable.
Support bar is connected with the elevating mechanism of table body bottom. Whole mechanism provides power by Worm reduction motor, through reducing gearWheel transmission, is sent to synchronous pulley by the power of Worm reduction motor, and changes into the motion of Timing Belt horizontal direction. ConnectConnect piece and be connected on Timing Belt, and along with its motion.

The first photoelectric encoder is connected with shaft coupling, and short chi is fixed on shaft coupling. When rotating, short chi drives the first photoelectric encoderWhen rotation, produce pulse signal, output to charactron by the subsequent treatment of single chip circuit, convert angle-data to and show.Suppose to do the straight line of 45 °, only need to observe on charactron, in the time that charactron shows 45, the angle of short chi is just 45 °. WithTime, the first photoelectric encoder is also because being fixed on the slide block with two linear bearings, and this slide block can form at two optical axisesOn guide rail, move left and right, long chi, except for long straight horizontal drafting, is used as the slide block being made up of two linear bearings in additionSign chi. Suppose to do the parallel lines of 45 ° of two distance to a declared goal, only short chi need be forwarded to 45 ° of positions, do straight line,Move left and right again slide block specific range, then do straight line. Use this mechanism can easily make the line of various diverse location relationsBar. Article two, optical axis is connected with the slide block of the table body left and right sides by axle bed, and slide block can be vertical on the line slideway of the left and right sidesMobile, just can realize the location of desktop drawing mechanism in whole plane in conjunction with moving horizontally of slide block. Slide block is also by connecting simultaneouslyPiece is connected with Timing Belt. Like this, on desktop, the vertical movement of mechanism just can drive Timing Belt motion, just can make and Timing Belt with thisThe second photoelectric encoder of wheel concentric rotates, and produces pulse signal, outputs to charactron aobvious after the processing of single chip circuitDisplacement data is shown. Suppose to draw the horizontal line of two specific ranges, first do a horizontal line by the short chi of long chi or 0 °,Vertical mobile whole mechanism again, moves to distance to a declared goal by observing charactron displacement data, then does a horizontal line, just obtainsArticle two, the horizontal line of distance to a declared goal. By the mechanical mechanism of whole assisted mapping, user can be drawn easily long straightLine, straight line and hatching etc. with angle, reduce time of drawing and the error of drawing, improves drawing efficiency. By what assistMeasuring mechanism is realized and being drawn without calibration, positions simply and easily and draws, and more can demonstrate intuitively some length dataAnd angle-data, thereby reduce artificial the reading error of bringing and the reading fatigue that reduces illustrator, improve the comfortableness of drawing.
