Description

The adjustable computer desk of full-automatic three-dimensional

(1), technical field

The utility model relates to the adjustable computer desk of a kind of full-automatic three-dimensional.

(2), background technology

At present, the people who is engaged in computer work is more and more, and the working time before computer is also more and more longer, neck ache harden, eyes are fuzzy dry and astringent, and the computer operater is suffered untold misery.Especially the teenager causes harmful effect to its growth, especially eyes is damaged.

(3), summary of the invention

In order to overcome the deficiency of existing computer desk, the utility model provides a kind of full-automatic three-dimensional adjustable computer desk, and it can alleviate the fatigue of neck and eyes effectively.

The technical scheme in the invention for solving the technical problem is: vertically the lower end of fixed axis is fixed on the carriage, the two ends of carriage are embedded in the vertical track, vertically track is fixed on the body, fixing fixed pulley on the carriage, on, following hollow shaft sleeve is outside fixed axis, by bearing fixing at the table body, on fixed mount and the carriage, the upper end cantilever mounted of last hollow shaft, sprocket wheel is decided in the fixed axis upper end, with the movable sprocket of deciding the identical parameters that sprocket wheel is connected by chain by bearing fixing on cantilever, fixing computer monitor on the movable sprocket, the lower end of last hollow shaft is connected with following hollow shaft by shaft coupling, fixedly strand cable wheel and belt pulley on the following hollow shaft, one end of strand cable is on the strand cable wheel, fixed pulley and the fixed pulley on the carriage that the other end is walked around on the desktop back side are fixed on the desktop back side, and the small belt pulley that links to each other with described belt pulley is fixed on the motor shaft, and motor is fixed on the carriage.

By adjust the position of display three-dimensionally, people's neck is being rotated unconsciously, alter one's posture, the focal length of eyes is also in automatic adjustment, thereby plays the effect of alleviating neck and eye fatigue.

(5), the specific embodiment

Shown in Fig. 1,4, vertically the lower end of fixed axis 36 is fixed on the carriage 29, and the two ends of carriage 29 are embedded in the vertical track 4, and vertically track 4 is fixed on the body 1.Fixing fixed pulley 27 on the carriage 29.As shown in Figure 3, upper and lower hollow shaft 16,33 is enclosed within outside the fixed axis 36, on table body 1, fixed mount 5 and carriage 29, upper and lower hollow shaft 16,33 can be rotated and move axially by composite bearing 17 and bearing 19,21, bearing 28 respective fixation.Rigid bearing 35 between the upper end of last hollow shaft 16 and the fixed axis 36, the upper end cantilever mounted 10 of last hollow shaft 16, sprocket wheel 15 is decided on fixed axis 36 tops, with the movable sprocket 12 of deciding the identical parameters that sprocket wheel 15 is connected by chain 13 by bearing fixing on cantilever 10.For movable sprocket 12 can be regulated along cantilever 10 directions,, cantilever groove 25 is arranged, as shown in Figure 2 on the cantilever 10 to regulate the display radius of turn where necessary.Fixing computer monitor 14 on the movable sprocket 12, cantilever have the support 11 that improves bearing capacity for 10 times.The lower end of last hollow shaft 16 is connected with following hollow shaft 33 by

shaft coupling

20, and 20 fens two sections of shaft coupling are fixing with bolt 18.Fixedly ear muscle 37 and belt pulley 31 on the following hollow shaft 33 take turns 32 by the detachable fixedly strand cable of fixing card on the ear muscle 37, as shown in Figure 3.One end of strand cable 6 is on strand cable wheel 32, and fixed pulley, the fixed pulley 8 on desktop 9 back sides and the fixed pulley 27 on the carriage 29 that the other end is walked around on the pulley yoke 30 are fixed on desktop 9 back sides.Be fixed on the axle of motor 26, as shown in Figure 5 with the small belt pulley 40 that described belt pulley 31 links to each other by belt 34.Motor 26 is fixed on the carriage 29.Table body 1 has drawer 22, keyboard 7, cabinet 23.For make about display 14 energy, up and down, the three-dimensional motion automatically in front and back, at track 4 appropriate locations difference fixed journey system switch S A1, SA2, so that the slide block 39 that carriage 29 two ends are embedded in the track 4 can make travel switch SA1, SA2 action, the contact of travel switch SA1, SA2 is connected on respectively in motor 26 positive and reverse rotation control circuits, as shown in Figure 6.

Need display 14 three-dimensional when mobile, press SB1 actuating motor 26, motor 26 drives carriages 29 and moves up or down by belt 34, strand cable 6, and promptly display 14 moves up or down.Meanwhile, following hollow shaft 33 drives by shaft coupling 20 and goes up hollow shaft 16 rotations, and last hollow shaft 16 rotates by the moving display 14 of cantilever 10 holders.Owing to decide the effect of sprocket wheel 15, chain 13 and movable sprocket 12, make display 14 identical with last hollow shaft 16, but direction is opposite from the angle that turns over, like this display 14 when rotation all the time over against the operator.Disconnect shaft coupling 20 or pull down fixing card and make strand cable wheel 32 break away from ear muscle 37, can make display 14 realize corresponding one-way movement or all around bidirectional-movement up and down.
