Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that in the feelings not conflicted
Under condition, the embodiment in the present invention and the feature in embodiment can be mutually combined.For sake of convenience, hereinafter as occurred
" on ", " under ", "left", "right" printed words, only represent that the upper and lower, left and right direction with accompanying drawing in itself is consistent, does not limit structure
It is set for using.
A kind of mechanical three legs automatic lifting table, as shown in figure 1, including 3 desktop 1,3 of Convenient table 4,1 liftings
3,1 table case 2 of leg.Wherein table case 2 and lifting leg 3 is connected by screw fixation, it is also possible to weld.Lifting leg 3 is enclosed on Convenient table 4
The inside.
As shown in Fig. 2 equipped with three rope-winding wheels 5, two bearing blocks 6, two torsion springs 7, four adjusting nuts inside table case
8, the first power transmission shaft 9, two bevel gears 10, locking device 11, second driving shaft 21 and locking switch 12.The fixing end of torsion spring 7
On bearing block 6, fixing end is arranged on adjusting nut 8, is connected through a screw thread between adjusting nut 8 and power transmission shaft, is
Prevent adjusting nut 8 from moving back under the active force of torsion spring 7 in a phenomenon, the present invention to be mounted side by side two adjusting nuts 8, one
Prevent torsion spring from rotating for installing torsion spring, another is responsible for stop.When torsion spring 7 is reversed, drive adjusting nut 8 to rotate, enter
And realize accumulation of energy.Bearing is installed so that the first power transmission shaft 9 is rotated on bearing block.The one end of first power transmission shaft 9 is provided with rope-winding wheel
5, the other end is provided with bevel gear 10；The one end of second driving shaft 21 is equipped with rope-winding wheel 5, and the other end is equipped with rope-winding wheel 5 and bevel gear
10.The present invention has filled identical bevel gear 10 at two two ends of power transmission shaft 9,21 and protected to ensure the synchronism of three table legs
Card coordinates intact, just can ensure the synchronization of two power transmission shafts in practical work process.
As shown in figure 3, rope-winding wheel 5 is separately mounted on the first power transmission shaft 9 and/or second driving shaft 21；Steel can be wound
Cord 13, the movable pulley 15 that steel wire rope 13 is bypassed on lifting leg, which is fixed on, to be buckled on 14.When desktop 1 declines, lifting
Leg 3 declines with desktop 1, and at this moment the movable pulley 15 installed in lifting leg lower end is forced to decline, and steel wire rope is wound with movable pulley 15
13, buckle on 14 because the one end of steel wire rope 13 is fixed on and buckle 14 and be fixed on Convenient table 4, will not move, at this time only
The other end of steel wire rope 13 can be driven to move, the other end of steel wire rope 13 is wound on rope-winding wheel 5, now rope-winding wheel 5 will be forced to rotate,
Discharge the steel wire rope 13 being wound on rope-winding wheel 5 and drive power transmission shaft 9,21 to rotate, and then make torsion spring 7 carry out reversing storage energy
Amount, while ensureing that two power transmission shafts 9,21 rotate synchronous by lazy-tongs, is ensured in three lifting synchronizations of leg 3 with this
Rise.
As shown in the mechanical three legs same table lazy-tongs schematic diagrames of Fig. 4, lazy-tongs are by two identical cone teeth
Wheel 10 is constituted, and the synchronization that two power transmission shafts 9,21 are driven is ensured by the engagement of bevel gear.
As shown in the mechanical three legs same table locking device schematic diagrames of Fig. 5, locking device includes locking switch 12, steel wire rope
13, horizontal arm-tie 16, upper cover plate 17, compression spring 18, portable plate 19 and lower shoe 20.Portable plate 19 can in the locking device
Moved up and down between upper cover plate 17 and horizontal arm-tie 16, compression spring 18 is housed between portable plate 19 and upper cover plate 17.Level
Arm-tie 16 and portable plate 19 are limited because four columns being fixed on lower shoe 20 are illustrated, and horizontal arm-tie 16 can be in level
Moved on direction, and be provided with inclined-plane above, portable plate 19 there are four extensions just to be moved on inclined-plane.Normal condition
Under, under compression spring effect, portable plate 19 is in the bottom of movable position all the time, when rotation lock switchs the rotation of 12 one end
During button, locking switch drives steel wire rope 13 above to move, and steel wire rope 13 drives horizontal arm-tie 16 to move, so as to drive portable plate
19 are movable in a vertical direction.Because portable plate 19 below be provided with semi-circular groove, press against second driving shaft 21, thus when portable plate to
During upper motion, power transmission shaft 21 can be released, just rotatably, while can also drive another power transmission shaft 9, be rotated, so that
Realize energy storage and exoergic.
The adjusting method of above-mentioned three legs automatic lifting table is as follows：
When desktop is in the top, it is necessary to open locking device, rotational lock switchs 12, at this moment power transmission shaft 9, and 21 will be rotatable,
Rely on external force simultaneously（Artificial pressing）, force desktop 1 to decline, steel can be forced by now lifting the movable pulley 15 installed the lower end of leg 3
Downwards, steel wire rope 13 will drive the rotation of rope-winding wheel 5 to discharge the steel wire rope 13 being wound on rope-winding wheel 5 to cord 13, rope-winding wheel 15
Rotation will drive power transmission shaft 9,21 to rotate, and now, power transmission shaft 9,21 can drive the torsion spring 7 on power transmission shaft 9,21 to carry out
Reverse energy storage.When dropping to suitable position, unclamping locking switch 12 can allow desk to be parked in desired position.
When desktop is in bottom, locking device is unclamped, rotational lock switchs 12, at this moment power transmission shaft 9,21 will be rotatable,
Now in the presence of torsion spring 7, power transmission shaft 9,21 will be rotated, and drive the rope-winding wheel 5 of transmission shaft end to rotate, so that by steel wire rope 13
It is wound on rope-winding wheel 5, with shortening for steel wire rope 13, it will drive lifting leg 3 to rise, this process is the inverse process declined.
When rising to suitable position, unclamping locking switch 12 can allow desk to be parked in desired position.
Can provide enough moments of torsion at the beginning in order to ensure torsion spring 7 at the beginning, the present invention specially set one can
The adjusting nut 8 of pretightning force is adjusted, a mouth has been opened so as to adjustment in good time in relevant position below table case, while in order to ensure
Adjusting nut will not be slided in desk lifting process, and the present invention is devised while installing two nuts, and previous nut is responsible for peace
One end of torsion spring 7 is filled, another is responsible for stop.
The content that above-described embodiment is illustrated should be understood to that these embodiments are only used for being illustrated more clearly that the present invention, without
For limiting the scope of the present invention, after the present invention has been read, the various equivalent form of values of the those skilled in the art to the present invention
Modification each fall within the application appended claims limited range.
